Architecture without documentation is incomplete

17 October 2020

Designing good architecture is only half the battle. You also need to be able to communicate your architecture to anybody who is likely to use it.

“Goldilocks” governance and agile architecture: balancing team autonomy and alignment

24 August 2020

There can be a tension between the lean, experimental nature of agile development and the more deliberate, planned demands of a large organisation. It does not have to be like this.

What we talk about when we talk about “legacy” systems

22 July 2020

“Legacy” is often used a pejorative term to describe any long-lived code base that a development team finds distasteful to work with. What do we really mean by “legacy” and how should we be dealing with it?

Naming things is easy. Abstraction is much harder.

13 June 2020

One of the more pervasive myths in software development is that naming things is hard.

Do you really need Kubernetes?

22 April 2020

If you are working with a lot of twelve-factor services then probably, yes. That said, you may get a creeping feeling that Kubernetes was designed to solve problems at a scale that most people never reach…?

If “Enterprise Architecture” is failing, what should architects be doing instead?

11 March 2020

The discipline of architecture is an important part of any efficient engineering organisation. It just needs to adapt its game from the process-orientated “Enterprise Architecture” of old to something more collaborative and relevant.

Don't use test coverage as a target

19 February 2020

Code coverage can be a useful technique for discovering untested parts of your code base, but it makes for a useless target.

When is an event not an event?

8 February 2020

Message design in an event-driven architecture can be quite nuanced, especially if you want to achieve any of the benefits of loose coupling that they can be associated with.

Running serverless containers in AWS Fargate, Google Cloud Run and Azure

26 January 2020

“Serverless” containers could help you to avoid the complexity of Kubernetes, but you may struggle to leverage them for anything beyond small, predictable workloads or batch jobs.

When should you write your own message endpoint library?

14 December 2019

Enterprise messaging patterns are complex beasts that often warrant a common implementation across your endpoints. Should you ever be tempted to roll your own?

There's more to publishing external APIs than choosing an API management vendor

17 November 2019

Publishing a public API involves many considerations, from billing and metering through to documentation and on-boarding. These are likely to be addressed through a collection of solutions rather than a single all-singing, all-dancing API management platform.

Using Azure Data Factory with the Application Insights REST API

28 October 2019

Persisting aggregates of AppInsights data in a warehouse can be a useful means of distributing summary information or retaining monitoring data over the long term. You can automate the harvesting of these aggregates using Azure Data Factory.

Splitting up shared databases

6 October 2019

The problem of shared databases is not confined to monolithic systems. A big store of shared state is the guilty secret lurking in many a microservice architecture.

Why trunk-based development isn't for everybody

9 September 2019

There’s more to adopting trunk-based development than deciding to shun long-lived branches. You need a confident development team, a loosely coupled code base and efficient build automation to make it stick.

Agile metrics. You get what you measure. In a bad way.

12 August 2019

Agile process tends not to generate the kind of metrics that management teams feed on. Should this be a problem?
