Given my (well-known and enduring) interest in all aspects of services, I have followed Martin Fowler's writing on microservices. But I will admit I always found the original paper more confusing than insightful. And in my client work I have resisted the temptation to use a microservices pattern, for precisely the reason that it would more than likely confuse. So I was interested to see the book Building Microservices by Sam Newman published last month, particularly as Newman is part of the Thoughtworks stable, which presumably means it is authoritative. 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 micr... (more)

Agile Governance | @DevOpsSummit #Agile #DevOps #APM #Microservices

“Last year the decision was finally made to mandate Agile across our enterprise. The decision was taken, even though there were many unanswered questions. The assumption was that forcing the migration, along with adoption of popular “enterprise Agile methods” would ensure resolution of the outstanding questions. In practice, Agile methods have been very effective in delivering specific digital business initiatives. But almost inevitably the distribution and delegation of architecture has resulted in duplication, inconsistency and increased complexity, across all project types inc... (more)

Using Cobit 5 Part 3 – The Policy Hierarchy

Many companies do not do governance well. A primary reason for this is a focus on governance “process” at the expense of policies. And, where policies are established, it is common to observe a surfeit of bad, inconsistent policies that are overlapping and generally ignored. As a result much governance is carried out by opinion; and governance decisions are not easily repeatable. The Cobit 5 framework provides reference models for process and goals but, other than providing very general guidance, stops short of any detail at all relating to principles and policy. However in fairn... (more)

Agile Architecture

The English language is well known for its subtlety. Sometimes it’s a delight, but on other occasions it can be very frustrating. If I use the term Gothic Architecture you will immediately understand I am describing a style of architecture that flourished in medieval times. And if like me you are interested in ecclesiastical architecture you will know that this style was used in many of the great cathedrals and churches across Europe, which were distinctive because of key architectural patterns that enabled great increases in height and internal light of the buildings without inc...

Understanding Business Services 2

In December 2006 I blogged on the topic of Explaining SOA to the Business Audience. It started out "I note resurgent interest in LegoTM blocks as a metaphor for explaining to the business audience the value of SOA. My advice is don't treat the business audience as dummies!" The blog goes on to explain business services using the Laundry metaphor, and how business people get the concept because they understand "services". However, while my explanation was and remains perfectly okay, I will be the first to admit that I have moved on. The basic service model works perfectly, but in... (more)
