Key Takeaways:

  • Distributed tracing is critical for understanding the interactions between microservices in complex systems.
  • Azure Monitor and .NET Core provide powerful tools to implement distributed tracing in C# microservices.
  • Efficient debugging and system latency reduction can be achieved through distributed tracing in microservices architecture.

Getting Started with Microservices using Azure

Microservices are an increasingly popular architecture pattern for building complex and scalable applications. At its core, this pattern involves breaking down an application into smaller, self-contained services that can be developed, deployed, and scaled independently, each handling a specific business function. Microsoft Azure is a cloud computing platform that provides a wide range of services and tools for building and deploying microservices.

There are many benefits to using Azure for microservices development. Azure enables rapid development and iteration, allowing developers to focus on building business value rather than managing infrastructure. Additionally, Azure provides a range of services for building, deploying, and monitoring microservices, including Azure Kubernetes Service (AKS), Azure Container Instances, Azure Service Fabric, and Azure Functions.

One of the key advantages of using Azure for microservices development is the ability to scale services quickly and efficiently. Azure offers a range of scaling options, from manual scaling to automatic scaling based on demand or custom metrics. This makes it easy to handle fluctuations in traffic and ensure that each service has the necessary resources to handle its workload.
