With the increasing prevalence and acceptance of the cloud as a viable alternative to on-premise IT, today’s IT organizations are faced with a wide range of options. In fact, had you just woken from a five-year slumber, you might find the available array of cloud service options quite daunting.
At just a moment’s notice, you can spin up pretty much anything, with Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) offerings all readily available. Services can reside on public clouds in multi-tenant environments, private clouds within the four walls of an organization, community clouds shared between a limited set of tenants, or even a hybrid arrangement.
For the many IT organizations mired in maintaining server and storage infrastructure, IaaS appears a very attractive alternative to managing hardware in-house. While it’s still a rare organization who seeks to move all their IT infrastructure to the cloud, there is a long list of benefits to strategically and selectively partitioning infrastructure using a hybrid strategy. Take a look at just a few benefits: reduction of capital expenses, maintenance expenses and avoidance of the often dreaded refresh cycles required on a 3-5 year basis.
But if you currently have all your infrastructure in-house, the dizzying array of options can obscure your view into where to even begin the incorporation of cloud into your environment.
For those organizations, it can be helpful – if not critical – to build a roadmap to cloud infrastructure services that provides simple entry points and can grow incrementally to encompass a broad set of high-value services.
While there is no “one-size fits all” path to cloud infrastructure adoption, a roadmap can ease and simplify the transition while minimizing disruption.
Below is a practical roadmap for rolling our cloud infrastructure in a phased approach:
Over the course of the next few blogs, I’ll be tackling each of these phases in greater detail. By taking a phased approach, you can much more easily transition from existing in-house IT to a hybrid cloud environment that minimizes the disruption to existing applications while still providing a clear path toward the increased use of the high-value services offered by cloud providers.
The first step? Data storage expansion. Stay tuned for my next post that will elaborate on this further.
Containers have changed the mind of IT in DevOps. They enable developers to work with dev, test, stage and production environments identically. Containers provide the right abstraction for microservices and many cloud platforms have integrated them into deployment pipelines. DevOps and containers together help companies achieve their business goals faster and more effectively. In his session at DevOps Summit, Ruslan Synytsky, CEO and Co-founder of Jelastic, reviewed the current landscape of Dev...

DevOps and microservices are permeating software engineering teams broadly, whether these teams are in pure software shops but happen to run a business, such Uber and Airbnb, or in companies that rely heavily on software to run more traditional business, such as financial firms or high-end manufacturers. Microservices and DevOps have created software development and therefore business speed and agility benefits, but they have also created problems; specifically, they have created software securi...

Software development is a moving target. You have to keep your eye on trends in the tech space that haven’t even happened yet just to stay current. Consider what’s happened with augmented reality (AR) in this year alone. If you said you were working on an AR app in 2015, you might have gotten a lot of blank stares or jokes about Google Glass. Then Pokémon GO happened. Like AR, the trends listed below have been building steam for some time, but they’ll be taking off in surprising new directions b...

DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, explored HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.

DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

Both SaaS vendors and SaaS buyers are going “all-in” to hyperscale IaaS platforms such as AWS, which is disrupting the SaaS value proposition. Why should the enterprise SaaS consumer pay for the SaaS service if their data is resident in adjacent AWS S3 buckets? If both SaaS sellers and buyers are using the same cloud tools, automation and pay-per-transaction model offered by IaaS platforms, then why not host the “shrink-wrapped” software in the customers’ cloud? Further, serverless computing, cl...
