Auditing with Azure Functions
In the previous two posts about recoverability, I focused on the rainy day scenarios where intermittent failures require retries and backoffs. This post will focus on the happy day scenario, where everything works as expected. So what's the issue then?

Recoverability with Azure Functions - Delayed Retries
In the previous post, I showed how to implement basic recoverability with Azure Functions and Service Bus. In this post, I'm going to expand on the idea and demonstrate how to implement a back-off strategy.

Recoverability with Azure Functions
When working with Azure Service Bus triggers and Functions, the recoverability story is not the best with the out-of-box implementation. To understand the challenges with the built-in recoverability and how to overcome those, this post will dive into the built-in recoverability with Azure Functions for Service Bus queues and subscriptions, offering an alternative. But first, what is recoverability?

Azure Blob Storage Cold Tier
Azure Storage service is the foundational building block in cloud architecture. Cheap, reliable, resilient, and powerful. From small solutions to monster systems, Blob service, in particular, is convenient. Any system that involves any type of document slowly but steadily has the number of blobs/files growing over time. Be it specific business requirements or legal aspects, blobs must be kept around for some time. But not all blobs are equal.

Manually Completing Service Bus Messages with Functions
Message settlement with Azure Service Bus has undergone some changes over the past few iterations of the Service Bus SDK for .NET. In the latest SDK (Azure.Messaging.ServiceBus), the settlement is performed via the
ServiceBusReceivedMessage. In the previous SDK, this was accomplished with the help of theMessageReceiverobject. -
Updating Azure Functions Tools
Azure Functions Tools is at the heart of providing local development for Azure Function. Whenever you use Visual Studio, Rider, VS Code, or anything else, you need it to be able to run your bits. For command line folks, the installation process is outlined in the tools repository. For Visual Studio (2022) and Rider, it is less evident as it depends on the tool. So, where am I heading with this? Right, the need to update the Azure Functions Tools.

Sagas with Azure Service Bus
Handling messages out of order is always tricky. The asynchronous nature of messaging makes it challenging. On top of that, systems in the real world are messy and unpredictable. That's why handling workflows always brings more complexity than just handling messages. To illustrate the challenge, I'll use a scenario where my workflow depends on two different services.
