PaaS and #Microservices: Part 6 By @bcferrycoder | @DevOpsSummit #DevOps #PaaS

We have a long way to go before many/most medium & large enterprises are able to achieve the benefits promised by microservices

This is the final installment of the six-part series Microservices and PaaS.

It seems like forever since I attended Adrian Cockroft's meetup focusing on microservices. It's actually only been a couple of months, but much has happened since then: countless articles, meetups, and conference sessions focusing on microservices have been delivered, many meetings and design efforts at companies moving towards a microservices-based approach have been endured, and five installments of this blog series have been written.

There's no doubt that microservices, like containerization and DevOps, is a trending topic these days. But this raises the question: How many enterprise organizations are actually using microservices architectures in production?

In spite of all the trending interest, the buzz, the hype, the articles, the sessions, the meetings, I submit that the answer is effectively...none are.

I say this, not based on costly analyst research, but from talking to literally hundreds of enterprise IT folks including developers, managers, ops people, sysadmins, architects, marketeers, and PR people, across a wide swath of industries. Based on this informal sampling, I conclude that the percentage of enterprises that have made any significant headway with microservices can reasonably be rounded down to 0%.

Heck, I recently talked to a couple of major enterprises who still have Windows XP servers sitting under their POS system in their retail outlets. Every evening, after the store closes, these servers dial home - yes, using a modem - and batch-transfer the day's transactions. I'm talking about well-known international brands here, companies that you and I and your friends and my friends have probably patronized in the last few weeks.

And at VMworld two months ago, a conference that's smack-dab in the middle of enterprise cloud technology, there wasn't a single session abstract (among hundreds) that even mentioned microservices.

While I agree with Adrian, who said at the microservices meetup that "2014 is the year that the enterprise finally gets the cloud," I would argue that 2014 is not that year that the enterprise finally gets microservices. That's still a ways off.

Don't get me wrong: microservices is certainly a significant trend these days, and many forward-thinking organizations are looking at adopting a microservices architecture, but we have a long way to go before many/most medium and large enterprises are able to achieve the benefits promised by microservices.

Action Plan
Get Started Now
I've rambled enough. It's time to see all this in practice. A natural first step in building microservices is to get the toolset in place. Stackato is a natural: it provides most of the features and capabilities discussed in this series, and is incredibly easy to set up and use. In fact you can get Stackato running in less time that it took you to read this article.

Check it out: download Stackato now, and see for yourself how simple it is to get a scalable, microservices platform in place, with powerful features such as scaling, load balancing, monitoring, logging, rollback, single signon, and more, instantly available.

What's Better than Best Practices?
I want to close by saying that the patterns and advice presented in this series are not meant to be construed as "best practices" by any stretch. Frankly, I don't particularly like the phrase "Best Practices" for a number of reasons. The term "Best" implies there are no better practices. But practices and technologies are always evolving. Adopting "Best Practices" can actually stifle progress and encourage complacency. Furthermore, there are oftentimes when "Best Practices" aren't really best for the situation at hand. Consider the well-known "DRY" (Don't Repeat Yourself) principle, a best practice that at times isn't really always best practice (for example: it's occasionally better to repeat code across multiple microservices instead of creating the additional complexity to abstract it). Finally, Best Practices might work for a particular team and a particular project, but adapting these practices to another team/project might be like fitting a round peg in a square hole, and be more costly than coming up with new, customized practices.

What's better than Best Practices? Why, No Practices of course! By definition, Best Practices require work: to learn, evangelize, educate, and adopt. But there's a better approach: No Practices. That's where PaaS comes in. Instead of investing in "Best Practices" to scale, or monitor, or rollback, or secure your applications, save the investment and use the tooling instead, which has many of these practices built-in.

That is, let Stackato do your practicing for you. This allows you, your developers and ops teams, and your organization to perform!

The now mainstream platform changes stemming from the first Internet boom brought many changes but didn’t really change the basic relationship between servers and the applications running on them. In fact, that was sort of the point. In his session at 18th Cloud Expo, Gordon Haff, senior cloud strategy marketing and evangelism manager at Red Hat, will discuss how today’s workloads require a new model and a new platform for development and execution. The platform must handle a wide range of rec...
When building large, cloud-based applications that operate at a high scale, it’s important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. “Fly two mistakes high” is an old adage in the radio control airplane hobby. It means, fly high enough so that if you make a mistake, you can continue flying with room to still make mistakes. In his session at 18th Cloud Expo, Lee A...

Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure ...
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
