If you're old enough, you probably remember the whole episode with Al Haig in the White House, saying "I'm in charge here" during the period when Reagan was shot. He wasn't really, but it's a good illustration of the concept of confusion, and how different people react to situations. How is this relevant to SOA and Web services? That's an excellent question.
As in a country, an organization implementing SOA needs governance and direction. A simple example may help shine a light on this subject. Let's suppose a division of a large company implements a new security service. Since it's only one division (let's suppose the company has some 50 divisions), they size the service to suit their needs only, and use a small server (maybe two for redundancy). Now, the service is successful, and other divisions start to use it, and so on. Pretty soon the service is up and down like an elevator, and when it is up, the response time is slow.
This illustrates why SOA and Web services need a governance model. Our hypothetical division implements the service for its needs, without considering the bigger picture. However, one of the goals of any SOA is reuse of services and reduction of redundancy, so any service that is successful needs to be designed for reuse. One of the key issues, of course is who pays for it. Why should that single division shoulder the burden of maintenance and equipment for the other 49 divisional needs?
Key concepts in the governance of SOA are cost and control. These two concepts go hand in hand - you can't expect control without expecting to bear the cost of the service. As services become more widespread and usage increases, organizations have to deal with scalability challenges, increased maintenance, and eventually with version-control issues.
Another key challenge is managing the reduction of complexity. Everyone is in favor of reducing the number of different ways to do the same task, as long as you don't touch MY way of doing things. One division of a large corporation surveyed its various applications and identified about 1,000 services. Then they did some comparisons and realized that because of redundancy, they could reduce the service count to fewer than 200. Over 80 percent of their software portfolio was redundant.
When things are that way, they are that way for reasons. Some have to do with specialized systems for special purposes - silos of useful functionality, but limited scope. It's not uncommon for organizations to have three or four or more systems for every real service - in telecommunications for example, it's often the case that they add a new billing system to account for new ways of doing business, rather than wait for changes to the old billing system. These are the problems SOA is designed to solve, but the key issue is governance. You may have heard the expression "You can have it fast, you can have it cheap, or you can have it quickly, but you can't have all three." Somewhere along the line the decision of whether we need it right now, or whether we will stick to a service interface and make changes has to be made. Fortunately, SOA allows us to put a façade in front of any new system to make it conform to the needs of the organization. In this fashion, it allows an organization to add new capabilities quickly, without compromising the overall integrity of the architecture. It also enables reduction of redundancy, without the pain of intermediate states of a system.
In order to achieve this nirvana - this heaven of software and services, there has to be order, and management and governance. The corporate equivalent of Al Haig must stand up, and say "I'm in charge here." However, in order for it to work, he must REALLY be in charge - and stick to his guns long enough to effect change.

Cloud computing is unquestionably one of the driving forces of DevOps, as the automation of operations transforms enterprise software development. DevOps, however, is more than a technology trend, as it represents a move toward silo-busting, self-organizing horizontal teams that drive business velocity. At the same time, enterprise Digital Transformation represents an upheaval across the enterprise, as customer preferences and behavior drive enterprise technology decisions. This transformation ...

The annual holiday shopping season, which started on Thanksgiving weekend and runs through the end of December, is undoubtedly the most crucial time of the year for many eCommerce websites, with sales from this period having a dramatic effect on the year-end bottom line. Web performance – or, the overall speed and availability of a website or mobile site – is an issue year-round, but it takes on increased importance during the holidays. Ironically, it is at this time of year that networks and i...

Most of the IoT Gateway scenarios involve collecting data from machines/processing and pushing data upstream to cloud for further analytics. The gateway hardware varies from Raspberry Pi to Industrial PCs. The document states the process of allowing deploying polyglot data pipelining software with the clear notion of supporting immutability. In his session at @ThingsExpo, Shashank Jain, a development architect for SAP Labs, discussed the objective, which is to automate the IoT deployment proces...

DevOps is an organizational and cultural rethink of how software-driven organizations can become organizations at velocity – agile enough to innovate and fast enough to deal with any change that comes their way. Information technology is a central enabler of DevOps, but today’s better-faster-cheaper technology is not the whole story, as tools are only as good as the people wielding them. The more fundamental story here is the organizational and cultural transformation necessary to take full adv...

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...

In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace. Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facin...

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.

You may have heard about the pets vs. cattle discussion – a reference to the way application servers are deployed in the cloud native world. If an application server goes down it can simply be dropped from the mix and a new server added in its place. The practice so far has mostly been applied to application deployments. Management software on the other hand is treated in a very special manner. Dedicated resources are set aside to run the management software components and several alerting syst...

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...
