Summary

High availability and scalability are crucially important architectural concerns. Almost every application and every architect try to implement high availability. Azure is a mature platform that understands the need for these architectural concerns in applications and provides resources to implement them at multiple levels. These architectural concerns are not an afterthought, and they should be part of the application development life cycle, starting from the planning phase itself.

Monitoring is an important architectural aspect of any solution. It is also the first step toward being able to audit an application properly. It enables operations to manage a solution, both reactively and proactively. It provides the necessary records for troubleshooting and fixing the issues that might arise from platforms and applications. There are many resources in Azure that are specific to implementing monitoring for Azure, other clouds, and on-premises datacenters. Application Insights and Log Analytics are two of the most important resources in this regard. Needless to say, monitoring is a must for making your solutions and products better by innovating based on insights derived from monitoring data.

This chapter was purely about the availability, scalability, and monitoring of solutions; the next chapter is about design patterns related to virtual networks, storage accounts, regions, availability zones, and availability sets. While designing solutions in the cloud, these principles are very important in building cost-effective solutions with increased productivity and availability.
