There are multiple ways to design a solution. A solution architect needs to take the right approach based on user requirements along with the architecture constraint of cost, performance, scalability, and availability. In this chapter, you will learn about various solution architecture patterns along with reference architectures and how to apply them in real-world scenarios.

In the previous chapters, you learned about the attributes and principles of solution architecture design. This chapter is both exciting and essential as you will be able to apply your learning to various architecture design patterns. In this chapter, you will gain an understanding of some of the significant solution architecture patterns, such as layered, event-driven, microservice, loosely coupled, service-oriented, and RESTful architectures.

You will learn the advantages of various architectural designs and examples that demonstrate when to utilize them. You will also gain an understanding of architecture design anti-patterns in addition to the following architecture design patterns:

• Building an n-tier layered architecture
• Creating multi-tenant SaaS-based architecture
• Building stateless and stateful architecture designs
• Understanding service-oriented architecture (SOA)
• Building serverless architecture
• Creating microservice architecture
• Building queue-based architecture
• Creating event-driven architecture

• Building cache-based architecture
• Understanding the circuit breaker pattern
• Implementing the bulkheads pattern
• Creating a floating IP pattern
• Deploying an application with a container
• Database handling in application architecture
• Avoiding anti-patterns in solution architecture

By the end of the chapter, you will know how to optimize your solution architecture design and apply best practices, making this chapter the center point and core of your learning.
