Businesses large and small are leveraging the cloud to run a variety of applications that are critical to their success. Tools for sales and customer management, inventory management, expense tracking, file storage and sharing, websites, and custom applications are just a few of the many cloud-hosted services that keep businesses running. The scalable and global nature of the cloud helps to create affordable and flexible applications in a web hosting solution for most businesses today. Since servers host these applications in the cloud, it only makes sense to load balance the servers in the cloud as well.
Real-world application performance can be unpredictable. To ensure maximum uptime and reliability, the CenturyLink Platform offers a portfolio of cloud load balancers to meet the unique requirements of your apps. Less complex applications can deploy shared load balancers, while more involved apps can use dedicated load balancers that support advanced OSI Model Layer 4 - Transport and Layer 7 - Application rules. SSL offloading is also available, from 100 Mbps to 500 Mbps.
Cloud Load Balancing from CenturyLink uses a multi-tenant, scalable, and programmable infrastructure presented to the customer as a service. The Dedicated Load Balancer uses Citrix® NetScaler®, the industry’s leading web application delivery solution.
Self-Service Cloud Load Balancers Create, configure, and manage pools of virtual servers using our intuitive user interface. Supports “round robin” and “least connections“ routing methods and multiple persistence options.
View Real-Time Status & Recent Activity Get complete access to the details of your cloud load balancing service at your fingertips — billing, bandwidth, and details on each pool of servers.
Setup in Minutes Point-and-click to configure your load balancer and assign up to 10 virtual servers per virtual IP address. Choose either “standard” or “sticky” persistence.
Benefits of Cloud Load Balancing
The benefits of cloud load balancing arise from the scalable and global character of the cloud itself.
Scalability Through simple-to-use self-management interfaces, cloud resources can scale to meet the demands of traffic spikes (like those on Cyber Monday) without degrading performance. By placing a cloud load balancer in front of a group of application instances nodes can be added and unhealthy nodes can be removed, allowing a web service to quickly grow and shrink in reaction to the level of demand.
Reliability The ability to host an application on multiple nodes within your cloud environment while representing that application to the web via a load-balanced Internet address can boost reliability. If a cloud resource should crash, the cloud load balancer can direct traffic away from the resource to resources hosted elsewhere in a business’ cloud environment.
Cost Effectiveness Ten years ago load balancer solutions were hardware appliances installed in a customer’s data center. These devices required care and feeding just as any hardware appliance. They also required expertise to fine tune and maintain them. The total cost of ownership for these devices limited their viability to large companies with large OPEX budgets, and lots of very bright people to keep the system running.
Small- and medium-sized business, while no less in need of a solution, typically can not justify the expense involved in buying, installing, and maintaining such a system. Today however, due to cloud load balancers, the cost equation is entirely different. There is no capital purchase, no direct cost for maintenance or support, and the service is billed based on usage.
Ease of Use Cloud load balancers are platform and protocol independent and do not require additional software on the load balanced nodes, i.e., agents. There is no special configuration. Since these are cloud load balancers, they are not tied to a particular server or cluster. They are independent cloud resources that can load balance across multiple cloud resources.
Cloud load balancers can deliver the performance and reliability benefits of hardware-based solutions at a much lower total cost of ownership. Because they run on the cloud, they are affordable even for smaller companies, and they are ideal for load balancing all the applications and web servers already in the cloud.
