This is another way prescribed to understand and articulate application behavior. All along, we have been bombarded with a number of software design and evaluation metrics. Finalizing all the right and relevant metrics for microservices is a good starting point in order to reach the goal of getting to know application behavior. The recommended solution is to have a centralized metrics service that gathers and stocks the decision-enabling statistics of each of the service operations. Microservices can push their metrics information to the metrics service. On the other side, the metrics service can pull metrics from the microservice. Metrics services are emerging as an important ingredient in the MSA world.

Overview of this book
Enterprise Architecture (EA) is typically an aggregate of the business, application, data, and infrastructure architectures of any forward-looking enterprise. Due to constant changes and rising complexities in the business and technology landscapes, producing sophisticated architectures is on the rise. Architectural patterns are gaining a lot of attention these days.
The book is divided in three modules. You'll learn about the patterns associated with object-oriented, component-based, client-server, and cloud architectures. The second module covers Enterprise Application Integration (EAI) patterns and how they are architected using various tools and patterns. You will come across patterns for Service-Oriented Architecture (SOA), Event-Driven Architecture (EDA), Resource-Oriented Architecture (ROA), big data analytics architecture, and Microservices Architecture (MSA). The final module talks about advanced topics such as Docker containers, high performance, and reliable application architectures. The key takeaways include understanding what architectures are, why they're used, and how and where architecture, design, and integration patterns are being leveraged to build better and bigger systems.
