Cloud Computing: What NOT to Do

It's important to weigh a Cloud solution versus the traditional approach through the lens of business value

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.

Thomas Bitman of Gartner wrote a blog post last year about why OpenStack projects fail. In that article, he outlined three particular metrics which together cause 60% of OpenStack projects to fall short of expectations: Wrong people (31% of failures): a successful cloud needs commitment both from the operations team as well as from "anchor" tenants. Wrong processes (19% of failures): a successful cloud automates across silos in the software development lifecycle, not just within silos.

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...
Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resource...
With so much going on in this space you could be forgiven for thinking you were always working with yesterday’s technologies. So much change, so quickly.

This is the challenge we faced when we looked to refresh our existing 10-year-old custom hardware stack to measure the fullness of trash cans and compactors.

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.
Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...
Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Let's just nip the conflation of these terms in the bud, shall we?

"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.

They are not.

One is about the application. The other, the network. T...
