Software Architect's Handbook

By: Joseph Ingeno

Overview of this book

The Software Architect’s Handbook is a comprehensive guide to help developers, architects, and senior programmers advance their career in the software architecture domain. This book takes you through all the important concepts, right from design principles to different considerations at various stages of your career in software architecture. The book begins by covering the fundamentals, benefits, and purpose of software architecture. You will discover how software architecture relates to an organization, followed by identifying its significant quality attributes. Once you have covered the basics, you will explore design patterns, best practices, and paradigms for efficient software development. The book discusses which factors you need to consider for performance and security enhancements. You will learn to write documentation for your architectures and make appropriate decisions when considering DevOps. In addition to this, you will explore how to design legacy applications before understanding how to create software architectures that evolve as the market, business requirements, frameworks, tools, and best practices change over time. By the end of this book, you will not only have studied software architecture concepts but also built the soft skills necessary to grow in this field.

Migrating to the cloud

Migrating a legacy application to the cloud is another way that it can be modernized. Although not every legacy application will be compatible with every cloud service, there are migration paths that will allow you to take most legacy applications to the cloud. Certain cloud services will be more suited to a particular application.

There are a number of reasons why a legacy application will benefit from a move to the cloud. It can reduce costs while at the same time providing greater levels of availability and scalability. A cloud provider will be responsible for the hardware and infrastructure. Depending on the cloud model (for example, IaaS, PaaS, or FaaS), it may also be responsible for the operating system and other services.

Some legacy applications have security vulnerabilities because they rely on older hardware and software. If they are migrated...
