One of my friends has a child who used to bring a blanket with her wherever she went. It didn't matter that it was a hundred degrees outside; she carried it more for comfort than to keep herself warm and safe. Not that it protected her in reality, but it provided the illusion of safety, which is often as important.
When Web services first burst onto the scene, which in my mind was the beginning of the SOA movement, one of the biggest challenges faced by early implementers was the perceived lack of security. Fear and uncertainty abounded, and it was years before the majority of IT organizations became comfortable with the level of security that could be provided.
What I find interesting at this juncture, when SOA is now a fairly well-established architectural paradigm, is that in many ways Security is the security blanket (you had to know this was coming) of SOA.
In looking at implementations of SOA and working with various organizations that are doing the implementations, I've begun to question exactly how vital security is in the overall scheme of things.
Don't get me wrong, I'm a proponent of security and I take it seriously - I'm not suggesting that security is unnecessary, or even that it's just a "nice to have." Far from it. At the same time, I think there's a difference between applying every security concept on the planet in the paranoid hope of keeping data "safe" and the intelligent application of concepts at the appropriate levels.
I've seen systems in the past that were brought to their knees by the improper application of security concepts. SOA implementations are equally vulnerable to poor implementations or improper use of techniques. Indeed, the nature of SOA makes it even easier for a mistake to cripple a service or even the entire architecture. All it takes is a service whose usage grows faster than expected to outstrip the capacity of a poorly planned security scheme and bring an organization to a crashing (and I do mean crashing) halt.
Sense, common or otherwise, must be applied to the design of a service-oriented architecture, especially with respect to security. If you've already authenticated a user, do you need to reauthenticate for every call? Does every field have to have security, especially if the service is for internal use only (or some other use with similarly limited vulnerability)? These and a host of other similar questions must be asked, and re-asked periodically, in order to ensure that the proper application of security will occur.
It's also useful to analyze the composition of a business process for just where security needs to be enforced. A common tendency is to consider every service as the proper level of granularity for enforcement. At the surface, approaching each service as the place to implement security seems reasonable, and many times it is. But some services are never called directly, or some convey information that has no value outside the context of the larger process. It may be sufficient to enforce security while entering the business process, rather than enforce it repeatedly at each step of the process by checking each and every service. A blind adherence to guidelines is very similar to carrying that blanket - it provides the illusion of security, without any real protection.
Security is a vital component of SOA; there should be no question about that. The ability to protect data, transactions, information and even networks from malicious attacks from without or from within is critical to many SOA implementations. But it must be applied intelligently, not blindly, for it to be an effective component and not simply a performance detriment.
Much of the value of DevOps comes from a (renewed) focus on measurement, sharing, and continuous feedback loops. In increasingly complex DevOps workflows and environments, and especially in larger, regulated, or more crystallized organizations, these core concepts become even more critical. In his session at @DevOpsSummit at 18th Cloud Expo, Andi Mann, Chief Technology Advocate at Splunk, will show how, by focusing on 'metrics that matter,' you can provide objective, transparent, and meaningfu...

The notion of customer journeys, of course, are central to the digital marketer’s playbook. Clearly, enterprises should focus their digital efforts on such journeys, as they represent customer interactions over time. But making customer journeys the centerpiece of the enterprise architecture, however, leaves more questions than answers. The challenge arises when EAs consider the context of the customer journey in the overall architecture as well as the architectural elements that make up each...

From the conception of Docker containers to the unfolding microservices revolution we see today, here is a brief history of what I like to call 'containerology'. In 2013, we were solidly in the monolithic application era. I had noticed that a growing amount of effort was going into deploying and configuring applications. As applications had grown in complexity and interdependency over the years, the effort to install and configure them was becoming significant. But the road did not end with a ...

In 2006, Martin Fowler posted his now famous essay on Continuous Integration. Looking back, what seemed revolutionary, radical or just plain crazy is now common, pedestrian and "just what you do." I love it. Back then, building and releasing software was a real pain. Integration was something you did at the end, after code complete, and we didn't know how long it would take. Some people may recall how we, as an industry, spent a massive amount of time integrating code from one team with another...

Admittedly, two years ago I was a bulk contributor to the DevOps noise with conversations rooted in the movement around culture, principles, and goals. And while all of these elements of DevOps environments are important, I’ve found that the biggest challenge now is a lack of understanding as to why DevOps is beneficial. It’s getting the wheels going, or just taking the next step. The best way to start on the road to change is to take a look at the companies that have already made great headway ...

In the world of DevOps there are ‘known good practices’ – aka ‘patterns’ – and ‘known bad practices’ – aka ‘anti-patterns.' Many of these patterns and anti-patterns have been developed from real world experience, especially by the early adopters of DevOps theory; but many are more feasible in theory than in practice, especially for more recent entrants to the DevOps scene. In this power panel at @DevOpsSummit at 18th Cloud Expo, moderated by DevOps Conference Chair Andi Mann, panelists will dis...

The goal of any tech business worth its salt is to provide the best product or service to its clients in the most efficient and cost-effective way possible. This is just as true in the development of software products as it is in other product design services. Microservices, an app architecture style that leans mostly on independent, self-contained programs, are quickly becoming the new norm, so to speak. With this change comes a declining reliance on older SOAs like COBRA, a push toward more s...

Digital means customer preferences and behavior are driving enterprise technology decisions to be sure, but let’s not forget our employees. After all, when we say customer, we mean customer writ large, including partners, supply chain participants, and yes, those salaried denizens whose daily labor forms the cornerstone of the enterprise. While your customers bask in the warm rays of your digital efforts, are your employees toiling away in the dark recesses of your enterprise, pecking data into...

Small teams are more effective. The general agreement is that anything from 5 to 12 is the 'right' small. But of course small teams will also have 'small' throughput - relatively speaking. So if your demand is X and the throughput of a small team is X/10, you probably need 10 teams to meet that demand. But more teams also mean more effort to coordinate and align their efforts in the same direction. So, the challenge is how to harness the power of small teams and yet orchestrate multiples of them...
