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.

Fitness functions can be a useful metaphor for guiding an emerging architecture, but you do have to invest in making sure they describe the right outcome.

Not only are layered applications difficult to maintain, but the common abstractions they are built on tend to give rise to inflexible implementations that have serious scalability challenges.

Azure Table Storage can be tuned for high throughput workloads, but you’ll probably be faced with some difficult trade-offs.

Learning React.js always starts so well, but adding Redux into the mix can make things unnecessarily complex. The lack of accessible examples doesn’t help – this is an attempt at writing a stripped down, bare bones introduction that focuses on the main ideas behind Redux.

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.

Maturity models are a management tool. When applied to technology solutions they often provide a weak analysis that describes a false progression.

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?
