One of the most interesting aspects of being a consultant is that I get exposed to any number of different facets of system design in the course of an assignment. While I tend to focus more on application and integration work, I find it fascinating to deal with the concepts of services in the context of infrastructure.
In the past, I've been called upon to design Service-Oriented Infrastructures (SOI) - the hardware and platform software, along with customizations for the needs of the actual deployment environment - instead of creating an application architecture. SOI is really a different way of looking at the concept of services - from the viewpoint of the operational staff.
Most of the time, we tend to view services from a line of business or at the very least an application development perspective. There's nothing wrong with viewing SOA this way - it's very important to break down the artificial walls created by applications into discrete services, and it provides great flexibility to the line of business, allowing for swift creation of composite applications. In SOA World Magazine, we give a great deal of attention to these questions.
We also look at the concept of "support services" on a fairly regular basis. Even when a business doesn't have a great deal of redundant applications, you can be fairly certain that the set of "support services" available will still be significant. These can be things such as security, auditing, logging as well as business intelligence and business activity monitoring that transcend a single application and become common services in support of line of business operations.
These support services quickly become ubiquitous, and we find that in reality, although they do not support direct business activity (i.e., they are not front-of-the-house operational services that directly produce revenue), they are in many ways just as important, if only from a risk avoidance and mitigation standpoint. Fail to have this house in order and you can be in a world of pain during an audit.
Infrastructure is what's on my mind this month, as far as services go. We're looking at SOA testing and the concepts of grid computing as they relate to SOA in this issue. And that got me thinking. Testing itself can be considered a service, at least for organizations that treat it with respect and rigor. The wealth of information that testing provides can be set up as a service to corporate dashboards and reporting systems that monitor the efficiency and effectiveness of a large IT organization. Obviously, this is mainly for large IT shops, but we can see that the principles of service orientation can be applied even to areas that are seen as supporting processes, not just to main-line business processes.
Grid computing, with the ability to bring capacity on line and to bear on a problem as needed provides another stunning opportunity to move from traditional means of operation to a service platform. Bringing CPUs to bear on a problem in a dynamic fashion, assigning additional network capacity to deal with peak loads, and allocating private connections on the fly in response to security needs are just a few of the capabilities that infrastructure vendors are building into their hardware and operating software.
Even more interesting is the concept of virtualization applied to a farm of CPUs and storage devices. Imagine a world where there are no discrete servers at all - instead, you ask for and receive a server image, complete with virtualized storage. Environments can be switched on the fly, so you no longer need three or more testing environments in order to do all your development and testing. Or even a world where you can lease out your excess capacity dynamically and recover it according to a set of SLAs that are also managed and monitored by the same management software that watches your SOA line of business services. It's here already, waiting for you to use it. Welcome to SOI..
This week, I joined SOASTA as Senior Vice President of Performance Analytics. Given my background in cloud computing and distributed systems operations — you may have read my blogs on CNET or GigaOm — this may surprise you, but I want to explain why this is the perfect time to take on this opportunity with this team. In fact, that’s probably the best way to break this down. To explain why I’d leave the world of infrastructure and code for the world of data and analytics, let’s explore the timing...

The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016. Security is a key component and benefit of the SDDC, and offers an opportunity to build security 'from the ground up' and weave it into the environment from day one. In his session at 16th Cloud Expo, Reuven Harrison, CTO and Co-Founder of Tufin,...

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.

Microservices Total Cost of Ownership: Too Soon? By @Aruna13 | @DevOpsSummit #DevOps #Docker #Containers #Microservices
Microservices are hot. And for good reason. To compete in today’s fast-moving application economy, it makes sense to break large, monolithic applications down into discrete functional units. Such an approach makes it easier to update and add functionalities (text-messaging a customer, calculating sales tax for a specific geography, etc.) and get those updates / adds into production fast. In fact, some would argue that microservices are a prerequisite for true continuous delivery. But is it too...

What we really mean to ask is whether microservices architecture is SOA done right. But then, of course, we’d have to figure out what microservices architecture was. And if you think defining SOA is difficult, pinning down microservices architecture is unquestionably frying pan into fire time. Given my years at ZapThink, fighting to help architects understand what Service-Oriented Architecture really was and how to get it right, it’s no surprise that many people ask me this question.

One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...

Approved this February by the Internet Engineering Task Force (IETF), HTTP/2 is the first major update to HTTP since 1999, when HTTP/1.1 was standardized. Designed with performance in mind, one of the biggest goals of HTTP/2 implementation is to decrease latency while maintaining a high-level compatibility with HTTP/1.1. Though not all testing activities will be impacted by the new protocol, it's important for testers to be aware of any changes moving forward.

The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
