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.

Design considerations for event-driven patterns

In this section, we will explain the various design considerations that need to be kept in mind before choosing EDA patterns for architecture implementation. The main considerations are the following:

  • Agility: Agility refers to the ability to cope with the rapid changes that happen in the environment. In the EDA pattern, components are loosely coupled. This ensures that changes that happen to one component do not affect the other components in the system. Hence, the degree of agility offered by the EDA pattern is high, making it an ideal choice for the design of systems that require continuous changes without any downtime.
  • Ease of deployment: The EDA pattern components are loosely coupled in nature, which makes their deployment very easy. For solutions that require maximum ease of deployment, event broker topology is a better option...
