Hyperscale operators are ‘aggressively’ growing their share of cloud service markets, according to the latest note from Synergy Research.

The analyst firm identifies 24 companies in all which meet its definition of ‘hyperscale’ – not surprisingly including the four main infrastructure players, Amazon Web Services (AWS), Microsoft, IBM, and Google – and argues these companies accounted for more than two thirds (68%) of the overall cloud infrastructure services market.

Back in December, Synergy noted that hyperscale providers operated more than 300 global data centres between them, expecting this number to surpass 400 by 2018. Of that figure, almost half (45%) of data centres were in the US, with China (8%), Japan (7%) and UK (5%) trailing far behind. The company says the current figure is now approaching 320.

This time around, the focus is on the growing dominance of the biggest players in cloud infrastructure markets, including infrastructure as a service (IaaS), platform as a service (PaaS), and private hosted cloud services. By comparison, in 2012 hyperscale operators accounted for 47% of each of those markets.

As Synergy puts it, the ‘scale of infrastructure investment required to be a leading player in cloud services or cloud-enabled services means that few companies are able to keep pace with the hyperscale operators…and they continue to both increase their share of service markets and account for an ever-larger portion of spend on data centre infrastructure equipment.’

“Hyperscale operators are now dominating the IT landscape in so many different ways. They are reshaping the services market, radically changing IT spending patterns within enterprises, and causing major disruptions among infrastructure technology vendors,” said John Dinsdale, research director and a chief analyst at Synergy. “Our latest forecasts show these factors being accentuated over the next five years.”

The term “hybrid cloud” has grown in popularity among established technology vendors, but one could be forgiven for thinking it’s a convenient “cloudwash” for companies to showcase progress while delaying an inevitable shift to public cloud. I say that because to focus exclusively on cloud overlooks the reality that almost every CIO in an established enterprise today is contending with legacy as much as the need to embrace new technologies. Some critical data centre hosted systems just don’t move to cloud so easily.

It’s all simply IT, which is why I call the effective combination of public cloud, managed service provider cloud, and dedicated infrastructure “hybrid IT”. It is by no means intended as a “catch-all”, so I feel I owe it to the reader to explain precisely what I mean and how established companies are successfully exploiting the benefits of such choice on their terms.

Hybrid is about choice

At its core, hybrid is about choice: Choice to work with the appropriate combination of an organisation’s on-premises infrastructure, managed services, private cloud and public cloud infrastructure and services. With the right knowledge and information, companies can optimise IT to balance cost, risk and agility.

The first question to ask concerns value. Hybrid IT allows companies to choose the infrastructure or service that delivers the best value for them at that time. Over time, the value delivered could change and an application that is hosted on-premises could be migrated to a cloud IaaS or SaaS. Changes in cloud services (functionality and price), availability of skills, geographic requirements or software / hardware maintenance needs can all trigger the push-pull of value delivered.

Global presence is a big pull factor for cloud. Throughout the past two years the hyperscale cloud providers have battled for global coverage supremacy, opening data centres in important legal jurisdictions and population centres.  Here cloud offers low-latency local infrastructure that is becoming vital to companies to improve the experience of their global customers. It also presents options for data sovereignty and regulatory compliance.

Don’t forget the workload: It is common for business critical applications to have resource, locality, dependencies, or indeed hardware requirements that mean they are both complex and costly to migrate to cloud. Some companies will choose to outsource to a specialist to reduce their support costs, and may consider a cloud migration as factors change over time.

Hybrid IT allows enterprises to exploit legacy investment

Most clients we work with have legacy systems that are core to their business and have run for 10 years or more. These legacy systems often run on platforms such as mainframes, IBM i and previous-generation enterprise servers that cannot be transferred to a public cloud or a commodity Windows/Linux environment.

Hybrid IT has allowed them to continue maximising their return on investment in functional legacy systems, while migrating applications to the public cloud that are easily refactored for that environment. This prevents enterprises being hindered in their ability to adapt and innovate, while also freeing up capacity in legacy infrastructure to absorb increased demands.

Hybrid IT mandates integration

No-one can deny the benefits of cloud when it comes to flexibility and future capital savings, but the cost associated with a wholesale cloud migration can vastly outweigh the benefits. It is also important to note the complexities associated with transferring applications and data to the cloud. Some systems simply aren’t suited for cloud environments and others require significant re-engineering.

Here’s the rub: New systems of differentiation and innovation are usually best placed in public cloud environments, and built cloud-native, but these can rely on transactions and datasets residing in legacy systems, for example a retail website that relies on back-office inventory management. The successful hybrid IT solution must cater for this integration, and in doing so an enterprise with legacy technology gains the agility to transform without going all-in to public cloud.

Success in hybrid also mandates integration of IT real estate. I have spent more than 15 years helping companies make sense of each wave of cloud, and there are many common mistakes that result from a simple truth: It’s all IT and it all needs managing wherever it runs. If an established IT department doesn’t pay the same attention to developing its toolset, skills and processes for cloud management as it does on-premises management, then things will go wrong. Furthermore, those tools and processes must be integrated. Only then, can you benefit from the choice and flexibility of hybrid IT.

Keeping pace with new technology deployment and management is unsustainable for all but the largest IT departments. As cloud service choices continue to expand an increasing number of businesses are seeking specialist help from managed service providers who are able to provide the integration, specialist tooling and skills needed to address the complexity and breadth of hybrid IT and make it work for businesses.

Journey’s end?

Hybrid is about the long-term evolution of IT estates. Almost every company has IT distributed across multiple infrastructures and service providers, and companies that embrace the Hybrid IT management challenge are empowered to move forward.

As technology becomes ever more critical to business, the world is not going to get simpler. The ultimate goal must be to deliver a single, consistent service experience across the combination of hybrid IT environments you choose, enabling an organisation to adapt and change with business and technology needs.

Automation, a key pillar of the DevOps movement, frees IT operations to focus on higher-levl work and collaborate with cross-functional teams. But what if your automation is so good that developers don’t need you anymore? Mike Gualtieri of Forrester Research coined the term NoOps in his controversial blog post “I don’t want DevOps. I want NoOps.” In the post, Gualtieri says, “NoOps means that application developers will never have to speak with an operations professional again.”

The visual model to declarative metadata representation to immutable deployment vision is in essence what SD is all about.
The secret to making this approach practical, and thus the key to understanding why SD approaches have become so prevalent, is the word immutable.

Once we get an SD approach right, we no longer have to touch the deployed technology whatsoever. Instead, to make a change, update the model and redeploy.

The purpose of event management and monitoring is to make sense of events, and while this may require some analytics and intelligence, the goal is an actionable alert — a meaningful notification that enables the right person to take the right control action. So, we may leverage predictive analytics as a form of artificial intelligence to achieve this goal, and we might even need to perform further analytics in order to get the information required to make a good decision.

This right-to-left flow provides us with the knowledge and wisdom to make effective decisions, which is the basis for effective automation.

In DevOps, those who can’t keep pace are often left behind. For many people leading DevOps initiatives over the past few years, this led to a painful choice of leaving security by the wayside. Many Waterfall-native approaches to security could not keep pace with their new DevOps-native requirements and they were shunned. Gene Kim and Josh Corman first sounded the death knell for security as we knew it during their 2012 RSA presentation, Security Is Dead. Long Live DevOps: IT at Ludicrous Speed. However, as with so many things in our world, necessity is the mother of invention. Leaving security out of the DevOps toolchain was not an option for some and unimaginable for others.
Fast forward four years and things have changed dramatically. We are on the cusp of a new era of security that lives at ludicrous speed. Software-defined security is crossing the chasm into the mainstream.

Poorly managed development projects are bound to crash eventually. It’s likely happened to you a dozen of times already. While writing code can be a lot of fun, managing code and dependencies can quickly become a maze of its own when you’re dealing with the continuous growth of your codebase and feature branches. At Stackify, we aim to make the lives of developers easier (and less frazzling). One way to de-stress your work is with the aid of continuous integration tools.

We talked a bit about the Software Development Life Cycle (SDLC) in a recent post, but today, we’re going to dig a little deeper into one specific and crucial element in the testing phase, particularly for Agile development: regression testing. Regression testing refers to the process of testing a changed or updated computer program to make sure the older software features – which were previously developed and tested – still performs exactly as they did before. One way to think about software regression is to think about somebody who implements a new air conditioning system in their home only to find that while their new air conditioning system works as expected, the lights no longer work.

In his keynote at 19th Cloud Expo, Sheng Liang, co-founder and CEO of Rancher Labs, discussed the technological advances and new business opportunities created by the rapid adoption of containers. With the success of Amazon Web Services (AWS) and various open source technologies used to build private clouds, cloud computing has become an essential component of IT strategy. However, users continue to face challenges in implementing clouds, as older technologies evolve and newer ones like Docker containers gain prominence. He explored these challenges and how to address them, while considering how containers will influence the direction of cloud computing.
