Overview of this book

Becoming a solutions architect requires a hands-on approach, and this edition of the Solutions Architect's Handbook brings exactly that. This handbook will teach you how to create robust, scalable, and fault-tolerant solutions and next-generation architecture designs in a cloud environment. It will also help you build effective product strategies for your business and implement them from start to finish. This new edition features additional chapters on disruptive technologies, such as Internet of Things (IoT), quantum computing, data engineering, and machine learning. It also includes updated discussions on cloud-native architecture, blockchain data storage, and mainframe modernization with public cloud. The Solutions Architect's Handbook provides an understanding of solution architecture and how it fits into an agile enterprise environment. It will take you through the journey of solution architecture design by providing detailed knowledge of design pillars, advanced design patterns, anti-patterns, and the cloud-native aspects of modern software design.

A traditional application builds a tightly integrated server where each server has a specific responsibility. Often, applications depend upon other servers for completeness of functionality.

As shown in the following diagram, in a tightly coupled application, the web server fleet has a direct dependency on all application servers and vice versa:

Figure 4.5: Tightly coupled architecture

In the preceding architecture diagram, if one application server goes down, then all web servers will start receiving errors, as the request will route to an unhealthy application server, which may cause a complete system failure. In this case, if you want to scale by adding and removing servers, it requires lots of work, as all connections need to be set up appropriately.

With loose coupling, you can add an intermediate layer such as a load balancer or a queue, which automatically handles failures or scaling for you.

In the following architecture diagram...
