A shift is finally occurring in the Cloud Computing discourse. Topics like "what is it" have been supplanted by more useful questions such as "should I do it?", "how should I do it?", and "when should I do it?" In appreciation of this new phase of Cloud Computing adoption, we'd like to offer some thoughts on some of the common pitfalls of both public and private Clouds so that you might avoid them as you evaluate and implement cloud solutions.
1. Not understanding the business value
It's important to weigh a Cloud solution versus the traditional approach through the lens of business value. If this is an existing service, can the Cloud truly provide a better solution than what you're currently doing? If new, what are the important business requirements that may drive you to select a Cloud deployment model? In the event of a service outage or a security breech, what's going to happen: is your plane going to drop out of the sky or just experience some minor turbulence?
2. Assuming server virtualization is enough
Running applications on virtualized servers increases performance metrics such as utilization and application portability, but server virtualization is just one component of a truly dynamic IT environment, one that can flex with changing application loads and business requirements. Holistic virtualization requires virtualization at all layers: network, server, storage, memory, data, middleware, and application. A narrow deployment of virtualization capabilities will reduce both the economic and performance advantages of a Cloud deployment, as well as limit your flexibility when dealing with external providers (think vendor lock-in).
3. Not understanding service dependencies
Given the challenges most enterprises have with executing server consolidation and/or data center optimization activities, there's no reason to believe that this will be done properly as companies migrate applications to private or public clouds. Put simply, most enterprises don't understand the multitude of interactions between services, data sources, and other applications that support their business functions over a daily/weekly/monthly cycle. Any attempt to port applications to the Cloud without this knowledge will likely result in broken applications, or worse...difficult to diagnose suboptimal performance.
4. Leveraging traditional monitoring
Even today, many enterprises rely on their end users to notify them of service outages or slowdowns (sometimes referred to as brownouts). When they finally become aware of a critical issue, the individuals responsible for each technology silo circle up on a conference bridge until the problem is isolated and resolved. The Cloud makes this remediation process difficult to execute: good luck trying to get your Cloud provider on that conference bridge! Cloud makes the underlying infrastructure supporting an application/service fluid, rendering traditional resource-based monitoring tools useless as in a diagnostic process.
5. Not understanding internal/external costs
It's a common misconception that moving an application to the Cloud relieves the enterprise of the burden of the people, process, and technology previously supporting that application. However, unless you can answer questions like "which operations person is going to be let go now that we've moved this application to the cloud?" or "what server/rack/row/datacenter can we shut down now that this application is in the Cloud?" you haven't reduced your costs - you've actually increased them. The harsh reality is unless you have the luxury of zero legacy IT, adopting a public Cloud service just increases the internal allocation of costs to the applications that remain in-house. Moving to a private Cloud has a different economic model, but still necessitates substantially different methods for cost tracking and allocation.
Our intent in sharing this was not to dissuade anyone from moving forward in the Cloud - quite the contrary. There are extraordinary business and IT benefits that can be reaped from effective leverage of a Cloud paradigm. The key word is effective - hopefully this post will help you more thoroughly consider the less-obvious elements necessary for successful Cloud adoption.
In the coming weeks we'll explore each one of these topics in more detail, providing specific insights on the challenges and offering potential solutions.

If you are new to Python, you might be confused about the different versions that are available. Although Python 3 is the latest generation of the language, many programmers still use Python 2.7, the final update to Python 2, which was released in 2010. There is currently no clear-cut answer to the question of which version of Python you should use; the decision depends on what you want to achieve. While Python 3 is clearly the future of the language, some programmers choose to remain with Py...

Opinions on how best to package and deliver applications are legion and, like many other aspects of the software world, are subject to recurring trend cycles. On the server-side, the current favorite is container delivery: a “full stack” approach in which your application and everything it needs to run are specified in a container definition. That definition is then “compiled” down to a container image and deployed by retrieving the image and passing it to a container runtime to create a running...

Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...

As the world moves towards more DevOps and microservices, application deployment to the cloud ought to become a lot simpler. The microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. In his session at 17th Cloud Expo, Raghavan "Rags" Srinivas, an Architect/Developer Evangeli...

Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...

Application availability is not just the measure of “being up”. Many apps can claim that status. Technically they are running and responding to requests, but at a rate which users would certainly interpret as being down. That’s because excessive load times can (and will be) interpreted as “not available.” That’s why it’s important to view ensuring application availability as requiring attention to all its composite parts: scalability, performance, and security.

There once was a time when testers operated on their own, in isolation. They’d huddle as a group around the harsh glow of dozens of CRT monitors, clicking through GUIs and recording results. Anxiously, they’d wait for the developers in the other room to fix the bugs they found, yet they’d frequently leave the office disappointed as issues were filed away as non-critical. These teams would rarely interact, save for those scarce moments when a coder would wander in needing to reproduce a particula...

What Is Emergent About Emergent Architecture? By @TheEbizWizard | @DevOpsSummit #DevOps #BigData #API
All we need to do is have our teams self-organize, and behold! Emergent design and/or architecture springs up out of the nothingness! If only it were that easy, right? I follow in the footsteps of so many people who have long wondered at the meanings of such simple words, as though they were dogma from on high. Emerge? Self-organizing? Profound, to be sure. But what do we really make of this sentence?

As we increasingly rely on technology to improve the quality and efficiency of our personal and professional lives, software has become the key business differentiator. Organizations must release software faster, as well as ensure the safety, security, and reliability of their applications. The option to make trade-offs between time and quality no longer exists—software teams must deliver quality and speed. To meet these expectations, businesses have shifted from more traditional approaches of d...

Information overload has infiltrated our lives. From the amount of news available and at our fingertips 24/7, to the endless choices we have when making a simple purchase, to the quantity of emails we receive on a given day, it’s increasingly difficult to sift out the details that really matter. When you envision your cloud monitoring system, the same thinking applies. We receive a lot of useless data that gets fed into the system, and the reality is no one in IT or DevOps has the time to manu...

Last month, my partners in crime – Carmen DeArdo from Nationwide, Lee Reid, my colleague from IBM and I wrote a 3-part series of blog posts on DevOps.com. We titled our posts the Simple Math, Calculus and Art of DevOps. I would venture to say these are must-reads for any organization adopting DevOps. We examined all three ascpects – the Cultural, Automation and Process improvement side of DevOps. One of the key underlying themes of the three posts was the need for Cultural change – things like t...

I’ve been thinking a bit about microservices (μServices) recently. My immediate reaction is to think: “Isn’t this just yet another new term for the same stuff, Web Services->SOA->APIs->Microservices?” Followed shortly by the thought, “well yes it is, but there are some important differences/distinguishing factors.” Microservices is an evolutionary paradigm born out of the need for simplicity (i.e., get away from the ESB) and alignment with agile (think DevOps) and scalable (think Containerizati...
