Twelve factor apps provide a methodology for building apps that are optimised for modern cloud environments. It’s only been achievable in the Microsoft world since the advent of .Net Core.

It’s easy to get caught up in unrealistic notions that you can re-write a legacy system or gradually decompose it. There are other, more pragmatic approaches that can help to modernise architectures and enable new development.

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.

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.

Event sourcing can scale very nicely, though this does depend on a number of key design decisions for the underlying event store.

We know that micro services are small and focused by design – just how small is this in practice?

REST is sometimes described as the next “evolutionary step” in service integration. The problem is that REST provides too much of a “dumb pipe” to support genuinely decoupled, fault-tolerant service integration.

Debates on the finer points of REST can bring out the worst in people as they seek to define what is and is not “RESTful”. In most cases the debate is unlikely to make the difference between success and failure for an API.

When developers first start using messaging they can be tempted to use it as a brand new hammer for every nail. Messaging brings a lot to the party, but it isn’t necessarily a suitable transport for fast, synchronous query processing.

An architecture based on tiers or layers is too inflexible to deal with the more flexible demands of modern systems, particularly when you working with high-volume systems that require distributed processing.

There’s nothing really new about many of the ideas that underpin microservices. Are they just an agile re-branding of SOA?

Developers who have been brought up on the certainties of ACID transactions often have a problem trusting eventual consistency. Once you start exploring the requirements in more depth this really so much of a handicap.

Structured and “Hackable” URIs are a staple part of SEO-friendly websites. Although developers generically expect to see them in HTTP-based APIs, they should be irrelevant to consumers of a fully RESTful API that leverages HATEOAS.

Agile principals encourage self-organising teams to take ownership of solutions. This doesn’t leave architects out in the cold, but it does require a more engaged role based on influence rather than governance.
