SOA World Editorial — Ready, Fire, Aim

We all do it from time to time - forget something or do something incredibly stupid

We all do it from time to time - forget something, get it out of sequence - and experience that annoying feeling that we've just done something incredibly stupid. I usually arrive at the dry cleaners to pick up my clothes, only to realize I'd left the next batch behind. Fortunately, it's not a long drive. But it's usually because I'm in a rush, trying to accomplish multiple things. If I slowed down just a second, I might accomplish more.

Service-oriented architecture faces similar challenges. In particular, the concept of architecture seems to be the one that gets left behind, or thrown out with the bathwater. Yet it's really the architecture part of SOA that enables it to provide the highest return on investment from an implementation.

I've gone on and on about architecture - what it is, why it's important, how to do it - in numerous issues of SOAWorld Magazine. Yet in many cases I still see organizations with the same old problem: "Ready, Fire, Aim!"

This is partially due to the challenges of providing an ROI on technology that is in many cases considered pure infrastructure. It's an old problem. Remember when you didn't have Internet access on the job, or it was a slow dial-up? Making the case that Internet access was important to the employee base was difficult - especially if you had to justify a move from limited dial-up to universal broadband. Sure, we all thought it was a good idea, but what was the monetary value to the organization? It was much easier to quantize the costs than to enumerate the benefits and place a value on them. And yet, eventually, the overwhelming majority of organizations have moved to broadband.

SOA is very similar. It's nearly impossible to quantify the business benefit of an SOA migration. The benefits are clear in an environment with multiple applications and strong integration needs, but at the same time, it's still a challenge to pin a number to them. Will an SOA increase productivity? Will it reduce maintenance costs? How much? How long will it take to reduce those costs? Yes, the questions sound like you're being pecked to death by the accounting duck, but they are also real issues. Bottom line in today's economy is that an SOA migration needs clear ROI justification.

Which is a challenge. Instead, organizations are using the grassroots approach to SOA. New projects have to include SOA. Old applications that are being renovated are encouraged to adopt SOA aspects. And slowly, through the process of accretion, an SOA arises from the muck.

The challenge is that by building SOA a system at a time, we're concentrating on the wrong end of the process and ignoring the role of architecture. We're building the same old silo - perhaps a little more open, but not a whole lot better than the system as it existed before the introduction of an SOA element.

This is why architecture is important. Without it, services arise at all levels of granularity. Processes have to be cobbled together haphazardly. Service rationalization and consolidation does not take place, so duplicate or nearly duplicate services exist long after they should have been rationalized to a single service. The retirement of redundant systems is delayed long after it could be accomplished.

Although it's rare to be able to fund a complete SOA overhaul, a best practice that should be followed is to set up an SOA Governance and Architecture group. The group doesn't need to boil the ocean in order to solve every problem, but as systems are reworked or introduced they can be the coordination point for rationalizing the enterprise to a set of identified services. They can also serve as the mediator in various negotiations around design and guide the IT organization as to how best to achieve an SOA given multiple options.

In the same way that I need someone to remind me to take my dry cleaning with me, we all need to have Architecture as part of SOA. Now where did I put that cleaning ticket?

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...

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...
Node.js and io.js are increasingly being used to run JavaScript on the server side for many types of applications, such as websites, real-time messaging and controllers for small devices with limited resources. For DevOps it is crucial to monitor the whole application stack and Node.js is rapidly becoming an important part of the stack in many organizations. Sematext has historically had a strong support for monitoring big data applications such as Elastic (aka Elasticsearch), Cassandra, Solr, S...

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor – all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organization...
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.
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...

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...
