Design patterns

Design patterns are proven solutions to known design problems. They are reusable solutions that can be applied to problems. They are not reusable codes or designs that can be incorporated as is within a solution. They are documented descriptions and guidance to solve a problem. The problem might manifest itself in a different context and design patterns can help solve them. Azure provides numerous services with each service providing a specific feature and capability. Using these services is straightforward, but creating solutions weaving multiple services can be a challenge. Moreover, achieving high availability, super-scalability, reliability, performance, and security for a solution is not a menial task. Azure design patterns provide ready solutions to these problems and provide solutions that can be tailor-made to individual solutions. They help in making highly available, scalable, reliable, secure, and performance-centric solutions on Azure. Although there are many patterns and some of the patterns are dealt in detail in the subsequent chapters, some of the messaging, performance, and scalability patterns are mentioned in this chapter. Also, links are provided for the detailed description of these patterns. These design patterns deserve a complete book by themselves. They have been mentioned here to make the readers aware of their existence and provide links for deeper information.
