August 25, 2014
By Jared Ruckle, Senior Product Manager. Find Jared on Twitter

A new vulnerability was recently identified in the “bash” shell that a default component of most Linux operating systems deployed globally today. This vulnerability – dubbed “Shellshock” - is being compared to what was experienced earlier this year with the Heartbleed bug because of the widespread use of the impacted Linux operating systems.

Shellshock has been assigned the highest risk rating of “10” according to the Common Vulnerability Scoring System (CVSS). Why? The vulnerability can be exploited across the network, it does not require any authentication to exploit, and exploiting this vulnerability is simple.

Private Cloud: Tradeoffs and Transformation

August 15, 2014
By Jared Ruckle, Senior Product Manager. Find Jared on Twitter

A few weeks ago, we announced CenturyLink Private Cloud – a new approach to the private cloud segment that offers breakthrough simplicity for large enterprises.  CenturyLink Private Cloud is designed for those looking to deploy a transformational private cloud, instead of eking out incremental gains.

Entering a new market segment is a significant undertaking for any product organization.  Every solution requires a series of trade-offs —just ask any product manager - and development of the CenturyLink Private Cloud is no exception.  So what were the trade-offs that we made, and how do they compare to other private cloud alternatives?  For a little insight into how we evaluated the private cloud market landscape and our decision making process, read on.

Homegrown solutions

Successful private cloud deployments – though more common these days – remain elusive. The brave souls that pursue a “do-it-yourself” approach often discover that:

  • Building a cloud is hard (especially the self-service and automation)
  • Running a cloud to 99.99% SLAs is hard
  • Just because you call it cloud doesn’t mean it is one
  • Users do not automatically gravitate to what you build
  • Lots of time and money are wasted when these lessons are learned the hard way. Forrester Research posted this great analysis of DIY private clouds:

Recognizing the Challenges of Hybrid Cloud – Part IV

August 9, 2014
By Richard Seroter, Director of Product Management. Find Richard on Twitter

Hybrid cloud is becoming a standard operating model for many organizations. But how can you realize the expected agility when there are so many challenges ahead of you? In this series of articles, we’ve dissected each challenge and proposed some corresponding solutions. Whether you’re facing security and network concerns, or integration and system management issues, it’s critical to have a proactive plan in place. This final article rounds out the discussion by looking at ways to address the issues around portability, compatibility, and your existing toolset.

Solutions to Hybrid Cloud Challenges

In many cases, a hybrid cloud is the combination of complimentary – but not identical – computing environments. This means that processes, techniques, and tools that work in one place may not work in another.

Compatibility. Gluing together two distinct environments does not come without challenges. Now, it’s possible that you have the same technology stack in both the public and private cloud environment, but the users, technology, and processes may be dissimilar!

  *Move above the hypervisor. Even if your public cloud provider supports the import and export of virtual machines in a standard format, no legitimate public cloud exposes hypervisor configurations to the user. If you want...

Recognizing the Challenges of Hybrid Cloud – Part III

August 8, 2014
By Richard Seroter, Director of Product Management. Find Richard on Twitter

As hybrid cloud adoption grows, proper architecture and design of these solutions becomes critical. In the first part of this article series, we discussed the challenges any organization faces when linking public and private cloud environments. The second article outlined strategies for mitigating the network and security challenges of hybrid cloud. In this third of four articles, we will assess success strategies for application integration and system management in hybrid clouds.

Solutions to Hybrid Cloud Challenges

Data and Application Integration. Nearly every useful system is made up of data and business logic from multiple applications. Siloed, monolithic systems are fading in popularity as more dynamic systems take their place. But as you look to work with data and applications in a hybrid cloud, you need to keep a few things in mind.

  *Recognize the presence of data gravity. The concept of data gravity—a principle identified by Dave McCrory that claims that applications and services are drawn closer to large collections of data—comes to play in a hybrid cloud. Do you find yourself shuttling data back and forth over long distances? Would it make sense to move some of your large data repositories to whichever cloud most of the consuming applications...

Recognizing the Challenges of Hybrid Cloud – Part II

August 4, 2014
By Richard Seroter, Director of Product Management. Find Richard on Twitter

Many organizations are adopting hybrid clouds – a bridge of public and private cloud environments – but there are many pitfalls along the way. In the first part of this article series, we looked at the challenges that any organization faces in their hybrid cloud journey. Now it’s time to see how to overcome these challenges. In this second of four articles, we will revisit the first set of hybrid cloud challenges and discuss strategies for success.

Solutions to Hybrid Cloud Challenges

Lasting success with a hybrid cloud requires strategic planning, investment, and yes, some compromise. By definition, you are using services that are outside of your control. Hence, existing processes and technologies may need to be revisited if you want meaningful integration and the flood of efficiencies that follow.

Keep in mind that every part of your organization cannot accommodate the same level of change associated with a hyper-efficient hybrid cloud. Lydia Leong of Gartner points out that organizations with “bimodal IT” – where pockets of traditional IT and agile IT co-exist – are most successful when they do NOT have a universal set of processes, tools, and skills. If your IT organization is bimodal, consider which parts of the organization...

Explaining the Managed Cloud with Three Key Equations

July 26, 2014
By David Shacochis, VP Cloud Platform. Find David On Twitter

Having been in the cloud infrastructure business since it came into existence, I’ve seen a number of different market forces shape and disrupt the industry.  The business side of my brain tends to focus on everything that’s changing.  But the engineering side of my brain tends to look for sustained constants in all the volatility. Sounds like a big data problem! Our data science team has crunched the numbers, and here are the key equations that help shape the managed cloud.

Ownership != Control

IT leaders often mistake having a tight grip on asset ownership with a tight grip on the steering wheel. With good but slightly misguided intentions, they want to own everything they use. This can lead to over-expenditure on common, undifferentiated hardware as well as under-utilized, over-engineered software products.  The own-it-all approach also builds a strong correlation between new IT projects and business growth initiatives, a situation that leaves IT permanently behind in delivering value to the business.

The critical challenge for any IT department is to provide an agility platform that addresses the digital needs of the business under competitive pressure.  The goal is to have true command and control over all IT resources, even if you don’t actually...

CenturyLink Makes Massive Private Cloud Massively Easy - Deploy in Over 55 Locations in 7 Countries

July 20, 2014
By Jared Ruckle, Product Management

Public cloud is an important part of enterprise IT.  Why?  Self-service.  APIs.  Automation.  Access to new features regularly.  Global reach. Outsourcing of infrastructure management.  OpEx consumption.

But it’s not the be-all, end-all.

Enterprise apps will always require a range of infrastructure options – Hybrid IT – including bare metal, traditional hosting…and private cloud.

The private cloud market is relatively immature (more on this in a forthcoming blog post).  The more we looked at this segment, the more we saw an opportunity to offer customers a unique value proposition.

“You got chocolate in my peanut butter…”

With CenturyLink Private Cloud, we’ve combined our approach to public cloud with the most important elements of a private cloud.

Public cloud-style agility, scale, and automation – running on dedicated hardware with physical isolation.  Available in over 55 data centers worldwide.  That’s CenturyLink Private Cloud.

We spare customers from the drudgery of infrastructure management, while offering more control over what truly matters: everything that happens from the platform up.

For example, administrators dictate who has access to the pod and what they can do on it – while wielding complete authority to govern how the node is used day-to-day.  If an instance in the public cloud is an apartment in a large building,...

Recognizing the Challenges of Hybrid Cloud – Part I

July 18, 2014
By Richard Seroter, Director of Product at CenturyLink Cloud

CIOs are adopting the hybrid cloud paradigm in droves, as we recently pointed out in a Forbes.com contributing article. As public cloud adoption continues to surge, organizations are turning their attention to connecting public compute resources to infrastructure residing in on-premises data centers. Can you just set up a VPN between the sites and call it a day? Hardly. Establishing a meaningful hybrid cloud requires considerate planning across many dimensions. How will you secure it? What does it mean to maintain services across organizational boundaries? Are workloads portable between environments? In this first of four blog articles, we’ll look at some of the biggest challenges that you’ll face as you set up a hybrid cloud environment.

What Challenges Will You Face?

Any vendor or consultant who promises a “seamless and straightforward” hybrid cloud is not being realistic. There are technical, cultural, and logistical challenges that await you. Let’s discuss a few that you should prepare for.

Security. This is usually the first item in any list regarding cloud computing, so why not this one too? As you plan out or mature your hybrid cloud, issues like compliance, identity management, and data protection will be front and center. Can you ensure data sovereignty...

Deploying Docker Containers on CenturyLink Cloud

July 13, 2014
By Bryan Friedman, Senior Product Manager. Find Bryan on Twitter

If you’ve been reading cloud-related news lately or you follow any developers or system admins on Twitter, then you’ve undoubtedly seen the words “container”, “Docker”, and “CoreOS” written a few thousand times over the past year or so. Chatter has particularly picked up in the last few months with Docker 1.0 being released in June and CoreOS announcing their first stable release within the past few weeks. CoreOS also received an 8 million dollar investment just a couple of months ago, and Docker just got another $40 million in funding a few days ago. And just yesterday, CenturyLink joined the container party and announced the release of the open-source Docker management platform, Panamax. Developed by the recognized thought-leaders at CenturyLink Labs, Panamax was described by RedMonk principal analyst James Governor as “Docker management for humans. It dramatically simplifies multi-container app deployment.”

This is bleeding edge technology we’re talking about here, so if you haven’t heard about any of it yet, there’s no time like the present. Docker is one of the fastest-growing open-source projects ever, with more than 550 contributors and 7 million downloads in just over a year since its release. The power of Docker lies in its ability to...

Scale All of the Things! Go In, Out, Up, Down in the CenturyLink Cloud

June 30, 2014
By Richard Seroter, Director of Product Management. Find Richard on Twitter

Are you getting the full benefit of the cloud if you don’t take advantage of its elasticity? To be sure, there are many ways that cloud environments—running dynamic OR static workloads—can positively impact your business agility. But cloud computing fundamentally changes the relationship between infrastructure and workloads that run upon it; you can constantly right-size by adding and removing capacity on demand instead of being stuck with over-sized or under-powered environments. To do this effectively, you need flexible options for automatically and manually adjusting your infrastructure resources. In this post, I outline five different application scenarios, and which CenturyLink Cloud scaling capability delivers the optimal elasticity solution.

1. Modern web application with variable usage? Horizontal Autoscale!

Horizontal AutoscaleAre most of your internal or external facing web applications in constant, heavy use? If so, I’d be surprised! The applications that your employees rely on may be busy during predictable periods, or, experience load whenever random business conditions occur. Public web applications may spike in usage when marketing campaigns are in flight, or when an avalanche of traffic follows a social mention.

Instead of standing up gobs of (costly) infrastructure that only add value during random usage spikes, consider services like CenturyLink Cloud Horizontal Autoscale. Our...

A Watershed Event for Cloud:  Managed Services On Demand

May 18, 2014
By Jared Wray, CTO of Cloud

We are in the business of solving real problems. That’s what our customers expect.  And today, we are announcing a new managed service that does just that.  Today we are introducing a cloud-based managed services offering that will help corporate managers minimize costs, complexity and risk while increasing agility and freeing budget for capabilities that transform the business and create competitive differentiation.  At CenturyLink, we believe that one of the most significant measures of problem solving is doing what we do best – managing the infrastructure that underpins the critical business initiatives of our clients and infusing that management with the automation and economics of our cloud platform.  Combined, those two elements deliver a value that no other provider can compete with today.  Infrastructure and people to run that infrastructure on-demand, paid for by the hour. Simply put, we are making cloud easier to manage for our customers.

We all know that Cloud is crossing a threshold into a new level of enterprise adoption possibilities. Enterprises now consider the cloud to be a basic necessity; a core element of their IT portfolios.  The challenge, however, is that most cloud platforms still operate on the do-it-yourself basis as cloud providers have...
