Cloud Application Manager

Service Guide

Updated: December 3, 2019

Product Description — Overview

Cloud Application Manager is a software-defined managed services orchestration platform that enables the configuration, deployment and management of applications within public, private and hybrid IT environments.

CenturyLink Managed Services Anywhere provides agile application configuration, deployment, patching, monitoring, troubleshooting, and optimization across a variety of private and public cloud platforms. These services are provided for a growing list of fully managed technologies in a highly orchestrated manner by a team of CenturyLink Cloud Application Manager power users leveraging automation. Advisory support is provided for other technologies. Services are accessible through the Century Global Operations Center.

Platform Advisory Support is only available outside of Managed Services Anywhere as a stand-alone option for customers who want to self-service manage some of their applications on certain cloud provider accounts via the Cloud Application Manager platform.

Not all Cloud Application Manager services and features are available in certain countries or regions. A CenturyLink representative should be contacted for a detailed list of geographic, sector, and feature availability.

Product Editions

Cloud Application Manager currently has the following two commercial versions available. Cloud Application Manager is not available for any public sector (e.g. federal, state, local or education) customer who requires FISMA or any other higher level security or regulatory requirements.

  • Cloud Edition — a SaaS experience that is accessed at
  • Datacenter Edition — a virtual appliance that runs on-premises in a Customer's datacenter or any other location including a Customer’s separately contracted public cloud environments. The Managed Services Anywhere support tier and the Cloud Optimization & Analytics feature (as more fully described in the features section below) is not available within the Datacenter Edition.

A. Cloud Application Manager Features

The Cloud Application Manager base features are described in the section below.

User Access

Users can integrate with their existing Authentication systems with the following authentication protocols:

  • Google Authentication
  • GitHub Authentication
  • SAML
  • LDAP
  • User ID and Password

Once logged into Cloud Application Manager, users can seamlessly navigate between Application Lifecycle Management, Cloud Optimization and Analytics, Monitoring and Ticketing portal sites using single sign-on. Cloud Application Manager users can access the entire functionality via API as well as User Interface at Users can create a permanent or a short- term authentication token that can be used to perform API calls.

Application Lifecycle Management

Application Lifecycle Management provides an orchestration environment for users to deploy and manage multiple environments across public and private cloud environments. This module allows for the modeling of infrastructure and applications in Cloud Application Manager once and deployment to any of the Compatible Cloud Provider environments. Users can choose to model applications in a cloud agnostic fashion or use one of the Compatible Cloud Provider’s native modeling templates like AWS Cloud Formation Template or Azure Resource Manager template. Once applications are deployed using the templates, users can manage the lifecycle of the application, auto-scale the infrastructure, update/patch applications without down-time and replicate them across environments.

Application Lifecycle Management also has a Continuous Integration and Continuous Deployment (CI/CD) plugin that can be configured to invoke policies in Cloud Application Manager and update applications and infrastructure residing in the underlying Compatible Cloud Provider platforms, on every code release. Customers can choose to use this functionality even without having to run the bill through Cloud Application Manager.

Application Lifecycle Management Compatible Providers

A current list of Compatible Cloud Providers is available in the KB article “Providers”.


The Auto-Discovery feature for instances running on AWS, Azure and CenturyLink Cloud infrastructure enables visibility of resources that have been previously running. Once a provider is configured, Cloud Application Manager discovers all of the virtual machine instances in that environment and lists them for the user. At that time, a virtual machine instance can be selected and imported. Users register an existing instance so the lifecycle can be managed within the Cloud Application Manager environment.

Additional features include:

  • Allows users to use single sign-on to access public cloud provider’s management console
  • Create a hierarchy of organization, cost centers and workspaces to organize resources to represent various internal environments, teams and departments
  • Allows users to model applications using the ALM framework for configuration management and reusability and build cloud agnostic applications
  • Allows users to leverage the cloud provider orchestration templates to deploy provider native services
  • Identity and access management allows the sharing of workspaces, applications and cloud infrastructure across your organization
  • Flexibility to deploy applications on all major cloud infrastructures to meet business demands and organizational preferences
Value Added Reseller Program (AWS and Azure)

Users can setup new AWS and Azure accounts or shift existing AWS and Azure accounts to CenturyLink Cloud Application Manager. There are three distinct options:

  1. Buy an AWS or Azure account directly from the provider or another 3rd party (not CenturyLink) to be used with Platform Advisory Support and Managed Services Anywhere (“BYOC”)
  2. Migrate account to CenturyLink for consolidated billing and support (designating Platform Advisory Support or Managed Services Anywhere) (“Brownfield”)
  3. Create a new account for consolidated billing (“Greenfield”)

Authorized Brownfield or Greenfield resale requires additional terms and conditions as a condition precedent to the Managed Cloud Provider setup process.

All AWS and Azure accounts are required to be fully hardened per the CenturyLink guidelines (see Permissions and Hardening Policy section)

Cloud Optimization & Analytics

Best Practices checks include more than 350 automated checks evaluated against Supported Cloud Service Providers (AWS and Azure):

  • Cost Savings
  • Security Utilization
  • Potential Monthly Savings, Idle Resources and Unused Resources
  • Change Monitoring Reports that list all changes performed by Managed Cloud Provider account
  • IAM Admin User Reports

CenturyLink provides cost optimization, spend analytics, chargeback and best practice recommendations for BYOC and approved public cloud providers. CenturyLink also provides consolidated billing for customers purchasing via CenturyLink’s Value Added Reseller program. Certain restrictions and limitations apply. Available for Platform Advisory Support and Managed Services Anywhere.

Technical Account Management (“TAM”)

Both support tiers provide customers with a technical expert and program governance agent(s) available on a next available basis. Technical Account Managers by way of example, support inquiries regarding Application Lifecycle Management, Cloud Optimization & Analytics, AWS and Azure services. The Technical Account Management responsibilities also consist of providing proactive service delivery plans based on the customer strategies, management of support escalations, answering advisory questions related to any of the three core Cloud Application Manager capabilities, addresses billing inquiries and coordinates more extensive architectural and design services from CenturyLink managed services experts.

TAM tasks provided under Platform Advisory Support

  • Provides Getting-Started activities
  • Provides support escalation, best practice and recommendations for additional hands-on services
  • Supports advisory-only level of guidance
  • Share and explain optimization reporting

B. Platform Advisory Support

Guidance in an advisory capacity is the baseline support tier of Cloud Application Manager and is automatically applied unless Customer designates Managed Services Anywhere against each Supported Cloud Provider account. Supported Cloud Providers for Platform Advisory Support are AWS and Microsoft Azure. This advisory tier includes all the Global Operations Support activities (see section D below) in addition to enabling CenturyLink to lead support responsibilities for Azure and AWS (when procured in a Brownfield or Greenfield scenario). For avoidance of doubt, all technology within the environment is treated as advisory only; CenturyLink does not perform or execute any tasks on behalf of the Customer.

Standard Cloud Application Manager Features Included with Platform Advisory Support

The base Cloud Application Manager features identified in Section A above are further described below as it relates to Platform Advisory support:

  • Application Lifecycle Management — All services and functionality of the Cloud Application Manager orchestration environment are subject to support. This includes modeling applications in boxes (templates), deployment policies, scripting and integration with development processes and tools. This functionality exists in both the Cloud Edition and Datacenter Edition versions and is covered in the Platform Advisory support tier.
  • AWS — Excluding BYOC, all native features and services are available for advisory support only and is not subject to any hands-on configuration or customization. Customers may contact the Global Operations Center for break-fix support and similar services comparable to that of AWS Enterprise Support. CloudWatch and other native AWS monitoring services may be consumed, supported and viewed via Watcher within Cloud Application Manager. However, the Platform Advisory Support does not include hands-on change, incident management and proactive remediation based on alerting. If escalations are needed, CenturyLink has the ability to engage directly with AWS for more support guidance.
  • Microsoft Azure — Excluding BYOC, all native provider features and services are available for advisory support only and is not subject to any hands-on configuration or customization. Customers may contact the Global Operations Center for break-fix support and similar services comparable to that of Microsoft Premier Support. Azure Operational Insights and other native Azure monitoring services may be consumed, supported and viewed via Watcher. However, the Platform Advisory Support does not include hands-on change, incident management and proactive remediation based on alerting. If escalations are needed, CenturyLink has the ability to engage directly with Microsoft for more support guidance.
  • Cloud Optimization & Analytics — Customers can use the CenturyLink Optimization & Analytics module.

Activities for AWS and Azure Advisory Technologies

  • Access to Global Operations Support
  • Monitoring alerts and notifications through Watcher
  • Investigate alerts for incident notification
  • General troubleshooting
  • Notification of upcoming service update windows (pushed by AWS or Azure)
  • Proactively notify incidents
  • Provide customer resources via knowledge base articles and vendor resources

C. Managed Services Anywhere

The Managed Services Anywhere support tier provides a complete management experience for hybrid IT environments. Managed Services Anywhere is designated at the Managed Cloud Provider account layer.

Customers must have or obtain and maintain all appropriate permissions to enable the installation by CenturyLink of a proprietary management appliance on each Managed Cloud Provider environment for which Managed Services Anywhere is selected in order to enable CenturyLink to perform it obligations. CenturyLink will also deploy a remote gateway on the appliance to establish a secure connection between the applicable customer environment (e.g. a Managed Cloud Provider environment) and CenturyLink to remotely monitor and access the managed applications within the Customer’s environment. The connection is monitored and maintained by CenturyLink.

Any changes to the customer network or environment by Customer that results in degradation or disconnection of the connection will result in CenturyLink’s inability to provide the Managed Services Anywhere service. CenturyLink’s management fees related to Managed Services Anywhere do not apply to the appliance itself. Instead Customer will be charged for the applicable Virtual Machine (VM) instance that the appliance runs on. See Remote Administration in the table below for further detail. Managed Cloud Provider charges for the VM usage related to the remote appliance will be reflected on the Customer’s cloud provider bill (e.g. either on the bill with the Managed Cloud Provider directly or via CenturyLink for Greenfield or Brownfield).

In addition to all of the base features of Cloud Application Manager listed in Section A above, the table below describes the standard operational functions of Managed Services Anywhere. CenturyLink reserves the right to require Advanced Managed Services or other upgrades (subject to additional terms and pricing) for any customer request that is not described in the tables below or otherwise deemed out of scope. Certain support services may be automated or provided by CenturyLink designated personnel as designated by Customer.

Activities Performed by CenturyLink within Managed Services Anywhere

Configuration Management
  • Confirm the initial install and basic functionality of the OS, application components and native cloud service based on Managed Cloud Provider recommended best practices.
  • Perform configuration management on the managed device via Cloud Application Manager’s remote administration functionality.
  • Maintain version control of deployed VMs, application and services.
Remote Administration
  • CenturyLink will perform systems administration tasks on the Customer’s behalf.
  • CenturyLink will maintain administrator-level access to all instances within the Managed Services Anywhere enabled Provider account; subject at all times to Customer ensuring that CenturyLink has the appropriate permissions.
  • Administrator level access permits CenturyLink to view instances, VMs, the databases, etc but does not allow or permit access to any customer data or information within the instances or VMs
  • Remotely access managed devices on the customer’s environment via the remote gateway.
  • In order to provide effective remote administration service for Windows Operating Systems, CenturyLink will establish a trust between customer’s managed workload and CenturyLink’s Active Directory domain hosted on the CenturyLink management appliance.
Patching and Maintenance
AWS and Azure Resale via CenturyLink only

Support and install available critical and vendor-recommended patches. Customers have full control to define when and if CenturyLink should schedule their patching cycles. CenturyLink’s automated system tracks the change request, performs the patch management and provides reports. This includes:

  • Approving and delivering service packs, cumulative updates and hotfixes for services running in the Managed Cloud Providers’ environments
  • Automated system tracking of change requests and performing the patch management
  • Providing status reports
  • Implementing specific AWS and Azure patch releases

Change Management activities through risk assessments, testing procedures, tracking metrics throughout progress, roll-back processes and post-deployment validation. Such changes are performed on behalf of the Customer and are available for auditing purposes. Customers are responsible for requesting the implementation of patch releases.

Maintenance Windows: All times listed under Schedule Maintenance Windows are local times and subject to change.

Access Management

CenturyLink manages user policies, administration and password management enforcement of Managed Cloud Provider accounts configured within Cloud Application Manager.


CenturyLink offers access to industry-recognized anti-virus protection intended to secure the OS, taking into account the guidelines of the Managed Cloud Providers, regular virus and malware signature updates, and offers OS-level hardening recommendations to mitigate risk on the Managed Cloud Provider environment. (See Permissions and Hardening section.) CenturyLink-licensed OS, CenturyLink Cloud, and Private Cloud on VMware Cloud Foundation OS builds are provided with the latest CenturyLink certified patches applied. Implementation of other recommended or client-required hardening steps is accomplished via the normal support ticketing process with Managed Services Anywhere.


CenturyLink will provide support for the following license types for the customer environments that are designated for Managed Services Anywhere, subject to the Permissions and Hardening section below:

  • Customer-provided licenses used and modeled within Cloud Application Manager.
  • Licenses provided by the native Managed Cloud Provider environments.
Watcher Monitoring and Alerting (limited to AWS and Azure)

The CenturyLink developed and proprietary monitoring service (Watcher), automatically integrated directly with AWS and Azure monitoring technologies, enables host, service, and application monitoring of Customer’s AWS or Azure cloud environments. The Watcher utilizes an intelligent agent deployed to all managed VMs. Monitoring policies are centrally configured and maintained by CenturyLink certified cloud engineers.

CenturyLink’s Watcher uses both agent based and cloud service provider integrations to collect metrics and generate alerts on the performance of the applicable record or log flagged for monitoring. Metrics are the result of standard checks that are performed and reported back to the customer and CenturyLink’s support organization.

  • Comprehensive monitoring policy is applied to all managed instances (e.g. VMs, database instances, storage instances, etc.).
  • Configurable monitoring policies for defining alerts and trigger based notifications via service request.
  • Change Management integration for automated suppression of alerts during maintenance activities.
  • Watcher dashboard to view policies and alerts on all managed devices, applications and services.
  • Graphing of performance metrics for managed workloads, applications and services enables historical trending and analysis.
  • Historical retention of the performance logs or records is currently on a rolling 14 calendar days basis. This can be adjusted via an Advanced Managed Services Upgrade package.
  • Graph overlays to compose and compare disparate metrics sets in a single view.
Disaster Recovery (DR) Readiness

Utilizing SafeHaven, a CenturyLink-developed disaster recovery tool (see Section G, SafeHaven below for further detail), CenturyLink enables Disaster Recovery (DR) Readiness on Customer’s Managed Cloud Provider infrastructure. Customers may optionally choose to have DR Readiness enabled for VMs that are under the management scope for Managed Services Anywhere at the Managed Cloud Providers account layer. The SafeHaven technology employed for DR Readiness utilizes HTTPS over the Internet for certain functions and requires an account and cloud infrastructure consumption with one of the available Managed Cloud Providers. Additional fees will apply for both the Managed Cloud Provider Services consumption and for CenturyLink’s Managed Services Anywhere management fees. Customers are responsible for performing Testing, Failover and Failback operations. Guidance in an advisory capacity for performing these operations is available by contacting Customer’s Technical Account Manager. If Customer requires hands-on assistance with Testing, Failover and Failback operations, Customer may elect to purchase the Disaster Recovery Add On available with Advanced Managed Services for additional fees.

CenturyLink certified cloud engineers provision, configure and administer DR Readiness in the Customer’s Managed Cloud Provider accounts for the source (production) and recovery platforms. DR Readiness is not currently available in CenturyLink’s LATAM region.

D. Managed Cloud Providers

Managed Services Anywhere is currently available for the following cloud service provider accounts, which may be modified or changed from time to time. The below listed cloud service providers are collectively referred to as “Managed Cloud Provider(s)”. This support tier must be selected for each individual subscription account:

  • CenturyLink Cloud — Supported for BYOC. CenturyLink Cloud must be procured separately (not able to be purchased within Cloud Application Manager)
  • CenturyLink Private Cloud on VMware Cloud Foundation — Supported for BYOC. CenturyLink Private Cloud on VMware Cloud Foundation must be procured separately (not able to be purchased within Cloud Application Manager)
  • Microsoft Azure — Supported for BYOC, new Greenfield resale accounts or pre-existing Brownfield accounts that shift over to CenturyLink for billing ownership
  • Amazon Web Services (AWS) — Supported for BYOC, new Greenfield resale accounts or pre-existing Brownfield accounts that shift over to CenturyLink for billing ownership

A more detailed list of Managed Cloud Provider Managed Technologies can be found in Appendix B.

E. Billing

Each of the support tiers (Platform Advisory Support and Managed Services Anywhere) is billed monthly based on the spend of the Managed Cloud Provider and consumed CenturyLink services. All Cloud Application Manager services are billed two months in arrears.

F. Permissions and Hardening

All Managed Cloud Provider accounts that are identified for Managed Services Anywhere or procured via CenturyLink’s Value Added Reseller program (AWS and Azure — in a Greenfield or Brownfield scenario) are required to be configured with the security and permissions identified below in order to accurately process billing as a percentage of Managed Cloud Provider spend for CenturyLink support services. Below are the required levels of access:

  • Root account access is required for all accounts within the CenturyLink Value Added Reseller program within Cloud Application Manager (includes both Brownfield and Greenfield accounts.
  • For BYOC accounts and access to billing, Customers retain their own root account access and CenturyLink is setup with an IAM admin-only policy.

Operational Access for Brownfield scenarios only

In order to complete migration of existing accounts to CenturyLink, Customer must give access to CenturyLink’s Global Operations Support personnel on their existing subscription(s) and designate CenturyLink the “owner role” so that resources can be transferred. This is a meta-data change and causes no downtime and does not affect connectivity. This meta-data change allows the Global Operations Support staff to review configurations within the account but does not permit adding, changing, or deleting resources. All support inquiries or tickets for accounts with Managed Services Anywhere must be opened via CenturyLink Global Operations Support and not directly with the underlying provider if the underlying provider is not CenturyLink. CenturyLink will take action designed to ensure permission and all policies and roles (collectively, “IAM Policies”) are enabled continuously or until the end of the applicable service term. Upon expiration or termination of the underlying agreement for services and migration to a successor account, Customer will continue to retain access to IAM Policies. Customer is responsible for ensuring that CenturyLink is removed as an administrator of the account(s) and that all root access rights have been disabled when the account is migrated.

AWS Account Security Configurations

Fully hardened, Customer AWS accounts created within or migrated into CenturyLink’s Value Added Reseller program must comply with the security best practices and operational access designated by AWS. When accounts are created or on-boarded, CenturyLink must initially be given programmatic access to accounts to enable the AWS designated security-related configuration and to permit appropriately permissioned CenturyLink employee access to the activities described in the operational access section above. All credentials provided by the Customer (if part of the Value Added Reseller program) will be encrypted by CenturyLink. The following steps will be taken during the set up or technical enablement of an account:

  • Confirm or set up events and logs storage for security event monitoring
  • Create IAM policies and roles for CenturyLink Global Operations Support
  • Create IAM policies and roles for Application Lifecycle Management, Watcher monitoring and Optimization & Analytics
  • Confirm or set up password policy
  • Confirm or enable root-account Multi-Factor Authentication access
  • Set up Account Controls
  • Enable audits of these configurations

Metrics and account information related to security events will be stored within the customer account and will be retained for the duration of the applicable service term.

For all Brownfield and Greenfield accounts, CenturyLink complies with the Managed Cloud Providers’ requirements to restrict the cost and spend information and other accounting/billing information in the Managed Cloud Provider portal account. Instead, this account and billing information is available within Cloud Application Manager and is provided at no additional cost through Cloud Application Manager’s Cloud Optimization and Analytics module.

G. SafeHaven

CenturyLink’s SafeHaven software (“SafeHaven”) is a distributed software architecture that delivers group consistency and run book automation for multi-tiered applications, automates data center disaster recovery orchestration, enables continuous recovery with group consistency and checkpoints, and provides recovery/redundancy for virtualized IT servers. SafeHaven also includes a graphical user interface and is compatible with multiple server operating systems.

As used herein, “data centers” refers to the infrastructure on which SafeHaven Replication Node (“SRN”) and Central Management Server (“CMS”) are deployed and configured. Customer may designate any supported data center as the production data center, and the remaining supported data centers would thereby be the recovery data center.

The SafeHaven software is comprised of certain open source software. Customers must install the relevant software on all desktop or laptop computers that Customer will use for SafeHaven administration. Please see the Knowledge Base article SafeHaven 5: Open Source Components for additional details.

SafeHaven includes the system components listed below and follows a structural hierarchy in the following order:

  • Cluster
  • Data Center
  • SafeHaven Replication Node (SRN)
  • Protection Group
  • Protected VM/Disk


A SafeHaven Cluster means the group of data centers and each SafeHaven cluster can service up to 64 virtualized data centers. A Customer may utilize any combination of virtual data centers and dedicated data centers.

A Central Management Server is an Ubuntu 16 based lightweight virtual appliance (virtual machine) in a recovery data center that connects all the data centers/appliances together and provides access to the DR environment via a SafeHaven console (GUI), which is a standalone java client (provided by CenturyLink) utilized to access the SafeHaven cluster.

Each SafeHaven cluster includes a single active Central Management Server (CMS). The CMS utilizes the SafeHaven virtual appliance installed at the recovery site and is part of the SafeHaven architecture that:

  • Receives commands from the SafeHaven console and relays them to the appropriate SRN in the appropriate data center.
  • Monitors heartbeats from the SRNs.
  • Receives state information from SRNs and relays it to the SafeHaven console.

Data Center

The data center layer is the set of data centers Customer chooses to provision as the recovery site(s) within a cluster via the SafeHaven console.

SafeHaven classifies data centers based on the API used for orchestration of recovery operations and recognizes the Managed Cloud Providers as DR target infrastructure. In the case of CenturyLink Private Cloud on VMware Cloud Foundation, virtual machine power on and power off operations are manual, meaning these operations are not automated through SafeHaven.

In cases where the data center is a third party Managed Cloud Provider, Customer may be responsible for configuring their account(s), using the third party services in a manner that provides security and redundancy, including enhanced access controls, encryption and backup, and ensuring CenturyLink has all appropriate permissions, credentials and access in order for CenturyLink to perform installation and configuration of SafeHaven. CenturyLink is not responsible or liable for any losses or damages related to the third party services, (direct or via any indemnity) including any liability, losses or damages related to unauthorized access or content or data loss and any losses or damages arising from or related to the installation and operation of SafeHaven on third party systems.

Any required network or internet connectivity between any of the data center types listed above is solely the responsibility of the Customer. Customer acknowledges that CenturyLink’s responsibility herein is related to enabling production and recovery environments and storage as detailed herein and such responsibility does not extend to any information, data or content that the Customer may send and/or store within such production or recovery sites. Customer is solely responsible for all data or content, in transit and at rest, whether in the DR or Production environment or in the storage space on disc as detailed in the SRN section below. CenturyLink is not liable for any losses or damages direct or via indemnity related to such data or information including any liability, losses or damages related to unauthorized access or content or data loss.


The SRN is an Ubuntu 16 based lightweight virtual appliance (virtual machine) which transfers and retains production data. This includes all SRNs provisioned within the SafeHaven cluster. Each SRN is associated with a data center as shown in the SafeHaven hierarchy. A given data center may include multiple SRNs. SRNs replicate at the LUN level transmitting updated blocks for each Protection Group to a peered SRN in a remote data center. Although each active Protection Group has a replica in only one other site, an SRN may support a set of Protection Groups that each have replica instances in distinct remote data centers.

Customer is responsible for purchasing and providing the following additional storage requirements or CenturyLink may not be able to provide the Service:

  • Customer must provide the required amount of disk space (i.e. “storage pool”) so the SRNs can perform their operations. The SRN will utilize the disk space made available by the Customer. Customer’s failure to maintain adequate disk space will cause the SRN operations to fail and will affect CenturyLink’s ability to provide the Service.
  • The production SRN must be provided with a storage pool of sufficient size to mirror the protected VMs.
  • The recovery SRN must be provided with a storage pool of sufficient size to host the protected VM disks inside the recovery site.
  • SRNs must also have enough storage for Protection Group checkpoints. The amount of storage allocated determines how many checkpoints will be retained in the checkpoint history.

Protection Groups

A Protection Group is a set of servers and hard disks grouped by SafeHaven that failover and failback together to the same instant in time and are shutdown and brought-up according to a prescribed recovery plan. Each Protection Group corresponds to a distinct set of servers and hard disks replicated to a remote site by SRNs. SafeHaven is set up to allow the applicable systems to recover via a remote data center with mutually consistent data images as they were at specific instances in time.

Each data center within a cluster can include both active Protection Groups and replica instances of remote Protection Groups. Protection Groups are logical mappings between the production and recovery servers. Protection Groups are created from within the SafeHaven console and users have the choice to either include one or multiple servers inside a single protection group. All the recovery operations are initiated from a Protection Group level.

Protected VM/Disk

Write traffic for each protected VM and hard disk is locally and synchronously mirrored within the production data center so that it is written both to the primary data store and also to a local SRN. For Windows Server Operating Systems 2008R2 and later, the SafeHaven local replication agent is employed and in Linux Operating Systems, Rsync is employed.


SafeHaven checkpoints correspond to LUN-level Copy on Write snapshots and are block-consistent representations of a Protection Group at an instant in time.
