Overview of this book

Well-written software architecture is the core of an efficient and scalable enterprise application. Java, the most widespread technology in current enterprises, provides complete toolkits to support the implementation of a well-designed architecture. This book starts with the fundamentals of architecture and takes you through the basic components of application architecture. You'll cover the different types of software architectural patterns and application integration patterns and learn about their most widespread implementation in Java. You'll then explore cloud-native architectures and best practices for enhancing existing applications to better suit a cloud-enabled world. Later, the book highlights some cross-cutting concerns and the importance of monitoring and tracing for planning the evolution of the software, foreseeing predictable maintenance, and troubleshooting. The book concludes with an analysis of the current status of software architectures in Java programming and offers insights into transforming your architecture to reduce technical debt. By the end of this software architecture book, you'll have acquired some of the most valuable and in-demand software architect skills to progress in your career.

Maintenance

Software maintenance is usually a great part of software life. In my professional experience, it's not uncommon for a project to be fully active (with a lot of new features and developments happening) for a couple of years, followed by many years of maintenance, which is focused on fixing bugs and keeping the product alive (without releasing any new features).

It goes without saying that the maintenance period can become more expensive than the building of the project. Moreover, but this is a consideration purely from an economic perspective, enterprises often find it easier to access the budget for building new applications (which is seen as money generating, or at least associated with business initiatives) than for maintaining and modernizing older ones (which is seen as IT for IT, which means that this is a project with no business impact, hence, purely a cost).

With that said, maintenance activities on existing applications can be roughly categorized into...
