In the last post, we talked about Monolith architecture (Part 2). Now we want to talk about technologies that enable microservice briefly.

In adopting microservices, a cautious and gradual approach to incorporating new technologies is advised. The initial focus should be on identifying issues stemming from the evolving distributed system and then exploring technologies that can effectively address those challenges. This process demands a comprehensive understanding of the supporting technologies, eroding traditional distinctions between logical and physical architecture.

Key technologies that play a crucial role in successful microservices implementation include log aggregation and distributed tracing. Log aggregation systems, such as Humio or services offered by public cloud vendors, facilitate centralized log analysis, enhancing troubleshooting and monitoring capabilities. Distributed tracing tools like Jaeger are instrumental in navigating the complexities of a growing system, allowing for efficient exploration and problem-solving across multiple services.

Containers, particularly managed by orchestration platforms like Kubernetes, provide essential benefits in terms of isolated execution environments. They ensure that issues in one microservice instance do not impact others, allowing for faster spin-up times and cost-effective resource utilization. Apache Kafka emerges as a pivotal choice for streaming data in microservices, offering features like message permanence, compaction, and scalability to handle large volumes of messages.

Public cloud providers, including Google Cloud, Microsoft Azure, and Amazon Web Services (AWS), offer an extensive array of managed services and deployment options. Leveraging these services becomes increasingly beneficial as the complexity of the microservices architecture grows. Notably, serverless offerings, falling under the umbrella of public cloud services, present an attractive proposition. These products abstract the underlying infrastructure, allowing developers to work at a higher level of abstraction. Function as a Service (FaaS) platforms, a subset of serverless, simplify deployment by handling code instances on demand, eliminating the need to worry about server provisioning.

This comprehensive suite of technologies forms the backbone of a successful microservices architecture. Carefully integrating these technologies ensures a robust and scalable microservices ecosystem, enabling organizations to navigate the intricacies of distributed systems effectively. We will talk more about these topics in subsequent posts.
