Don’t get me wrong - I am an advocate of decomposing functionality into autonomous services. My reservation is that you need to have a lot of prerequisites in place before you can start leveraging microservices.

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

Serverless computing makes bold promises of development without having to worry about environments, scaling or deployment. Haven’t we been here before?

In most cases “business logic” just refers to the poorly-defined “gloop” that sits between user interfaces and databases in layered architectures.

An API gateway can solve many generic problems in an API infrastructure, but you do need to define a clear remit and protect against creeping scope.

You might be able to identify cross-cutting concerns in a monolith, but in a service-orientated world they should melt away into specific implementations.

Large scale rewrites of systems are loaded with risk. You can address this by preparing the ground in advance and adopting an incremental approach, but a willingness to be pragmatic is essential.

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

Google’s open source serialization format is an efficient way of passing platform-independent and version-tolerant data between end-points. Two very different implementations have emerged for .Net.

Many developers confuse asynchronous operations with parallel execution. The essential difference is that an asynchronous operation is concerned with which resources you consume while parallel execution is more concerned with how many.

CQRS is based on the simple notion that you use a different model to update information than the one to read it. This does not necessarily have to give rise to the same solution every time.

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.

Given how important APIs have become in driving the reach of applications and services, it’s surprising how little investment is made in the usability of APIs as opposed to UIs. Perhaps the principals and techniques used by UX should be applied to developing more effective APIs…
