Events, sagas and workflows: managing long-running processes between services

4 November 2017

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.

Can consumer-driven contracts manage breaking change in microservice integrations?

4 June 2017

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.

Comparing serverless C# and .Net development using Azure Functions and AWS Lambda

26 May 2017

Recently released toolsets for AWS Lambda and Azure Functions are finally making serverless application development available to C# developers.

API management and the return of the enterprise service bus

16 May 2017

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?

Handling Protocol Buffers backwards compatibility between versions 2 and 3 using C#

13 November 2016

You will inevitably be pushed towards upgrading your protocol buffer messages to Proto3, particularly if you want a client that supports .Net Standard that .Net Core. This can be done, but there are a couple of speed bumps along the way.

What’s so bad about monoliths anyway…?!

3 October 2016

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.

Should microservices share technologies and platform capabilities?

28 June 2016

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.

Managing services that don’t have clear code ownership

5 May 2016

How do you organise code ownership for services that do not align conveniently with team or organisational boundaries?

Data design for event-driven architecture: autonomy, encapsulation and ordering

1 February 2016

When you’re implementing an event-driven architecture, the design of your events is absolutely critical to realize the benefits of loose coupling.

Pragmatic REST: APIs without hypermedia and HATEOAS

12 December 2015

If you’re not using HATEAOS then you’re not using REST. That’s true enough, but in many cases adopting HATEOAS doesn’t deliver much value beyond architectural purity.

Comparing nServiceBus and MassTransit: Do we still need .Net integration frameworks?

26 November 2015

Both nServiceBus and Mass Transit plugged an important gap in Microsoft’s integration landscape, but do they have a role in a future that is likely to be dominated by diverse technologies and autonomous agile teams?

Can cross-cutting concerns really exist between services?

25 July 2015

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.
