You’re rarely given the opportunity to focus on transitioning an architecture to the exclusion of everything else. You may have to get used to the idea that decomposing a monolith is a direction of travel rather than a clear destination.

One of the main benefits of microservices is that they reduce the cost of change. The problem is that you need to make a significant up-front investment to realise this saving. Your first few microservices are more likely to be an expensive and potentially painful undertaking.

Agile teams still need to make architecture decisions, but in supporting them architects should seek “just enough” architecture over “big design up front” and practical solutions over large-scale abstract thinking.

On the face of it, TOGAF describes a very different world to the agile preference for working software over documentation. That doesn’t mean that TOGAF is incompatible with agile, so long as you’re prepared to adapt its numerous building blocks.

Finely-grained, entity-based services seem to be advocated by some pretty authoritative sources. This is unfortunate as they are something of an anti-pattern that can undermine many of the benefits of decomposing an monolith into micoservices.

An event-driven architecture can give rise to complex chains of events that are difficult to manage. These problems can be mitigated through careful design rather than resorting to shared state databases or workflow engines.

The Scaled Agile Framework talks about an “architectural runway” as the main deliverable for agile architecture, yet it’s vague on the detail of what this looks like.

Agile teams spend time modelling software whether they are prepared to admit it or not. Adopting a technique like Domain Driven Design can help to make this more efficient, particularly at scale.

One of the more enduring problems with service integration is managing change in service interfaces. Consumer-driven contracts can help to detect breaking changes, but this visibility comes at a price.

No self-respecting integration platform is complete without an API management story these days. Is this just a RESTful return of the enterprise service bus?

Governance doesn’t have to be all about byzantine process and suffocating approval boards. It can be used to provide clear permission for teams to innovate.

No architect will ever admit to being out of touch with software development. However, unless you are writing code then it’s difficult to avoid becoming an ivory tower or PowerPoint architect that can only discuss systems in the abstract.

Event stores and event sourcing are a powerful idea, but they can be vulnerable to a number of technical and operational challenges when faced with real world complexity.
29 July 2016
Event sourcing can scale very nicely, though this does depend on a number of key design decisions for the underlying event store.

Should agile teams be encouraged to share capabilities or be given total autonomy over their technology choices? For larger organisations this can become a trade-off between economies of scale and speed of delivery.
