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.

Remote procedure invocation (RPI) pattern

Microservices have to interoperate with multiple microservices in order to complete any complex functionality. For this purpose, services use an inter-process communication protocol. The solution approach is to leverage the RPI for any inter-service communication and collaboration. The client uses a request/reply-based protocol to make requests to a service. The well-known RPI technologies include REST, gRPC, and Apache Thrift. This pattern is easy to implement and there is no need for any intermediate broker for facilitating the intended communication. However, there are a few critical drawbacks being associated with this pattern. That is, services are tightly coupled and have to be online to find, bind, and interact. Other prominent interaction types such as notifications, request/asynchronous response, publish/subscribe, and publish...
