Why duplication isn’t always a bad thing in micro-services

From an early development age, I was taught, that duplication is a bad thing. Especially when it comes to storing data. Relational databases were invented to show data that relates to each other and be able to store them efficiently. There are even a few normalization rules, to be able to avoid data redundancy. We… Continue reading Why duplication isn’t always a bad thing in micro-services

Receive Service Bus messages in Service Fabric

This is one of the proof of concent that I did at work. The idea was to add another Service Bus application to an existing solution, instead of starting a whole new micro-service. It was a lot faster just to add another .net core console application, but setting up Service Fabric cluster always brings some unexpected… Continue reading Receive Service Bus messages in Service Fabric

Microsoft Orleans – is it fast?

Microsoft Orleans is a developer-friendly framework for building distributed, high-scale computing applications. It does not require from developer to implement concurrency and data storage model. It requires developer to use predefined code blocks and enforces application to be build in a certain way. As a result Microsoft Orleans empowers developer with a framework with an… Continue reading Microsoft Orleans – is it fast?

Managing ServiceBus queues, topics and subscriptions in .Net Core

From version 3.1 of Microsoft.Azure.ServiceBus it is finally possible to manage queues, topics and subscriptions in .Net Core. Let’s have a look at how we can use it in real life scenarios. Previously we would use sample code for getting a queue:

Using ManagementClient we can write much better code.

Now before getting a… Continue reading Managing ServiceBus queues, topics and subscriptions in .Net Core

Implementing deferral mechanism in ServiceBus

Deferral is a method to leave a message in a queue or subscription when you cannot process it at the moment. When using PeekLock read mode you read a message but leave it in a queue. When processing of a message is done, you call Complete and message is removed from queue, but when something… Continue reading Implementing deferral mechanism in ServiceBus

Receive message from queue in push model

Push and pull models are in general approaches of distributing the data between services. In the context of messaging it mean how messages are received by the client. In the previous post I showed how to receive messages by waiting for them to come – this is pull model. Receive method will wait some amount of time… Continue reading Receive message from queue in push model

Azure Service Bus – introduction

Azure Service Bus is a Microsoft implementation of a messaging system, that works seamlessly in the cloud and does not require to set up a server of any kind. Messaging is a good alternative for communication between micro-services. Let’s compare the two. REST communication contract constrains may be a risk synchronous model be default load… Continue reading Azure Service Bus – introduction
