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

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.

API management and the return of the enterprise service bus

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#

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…?!

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?

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

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

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

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?

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?

Using the REST API connector as a data source in Informatica Cloud

It can be pretty straightforward to read REST API resources using Informatica Cloud – so long as you know which levers to pull and your data is in a sympathetic format.

Can cross-cutting concerns really exist between services?

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.

Refactoring large monoliths to microservices: strategies, risks and pragmatic reality

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.

Microservices, REST and the distributed big ball of mud

The “big ball of mud” describes a system architecture that is sprawling, sloppy and haphazard. That’s precisely how you’d describe some emerging microservice architectures.

How big is a microservice?

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

Protocol buffers for .Net: protobuf-net vs protobuf-csharp-port

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.
