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.

The distributed client-server architecture

The n-tier client-server architecture used for the shopping cart web application, which is discussed in the earlier section, is an ideal example of a distributed client-server architecture. Distributed architectures typically have some kind of backend host components (such as Mainframe, Database server, and so on), an intelligent client in the frontend, and multiple agents in the middle, which takes care of all activities pertaining to transactions like transaction processing, security, handling messages, and so on, and a network for communication.

Some of the key concepts associated with distributed architectures are as follows:

  • Transaction processing: Transaction processing is the automated processing of transactions in order to update a shared database. A transaction processing application in general will have many users who are...
