Cloud Architecture refers to the various components in terms of databases, software capabilities, applications, etc. engineered to leverage the power of cloud resources to solve business problems. Cloud architecture defines the components as well as the relationships between them.

Design patterns are useful for building reliable, scalable, secure applications in the cloud.

Each pattern describes the problem that the pattern addresses, considerations for applying the pattern, and an example based on Microsoft Azure. Most of the patterns include code samples or snippets that show how to implement the pattern on Azure. However, most of the patterns are relevant to any distributed system, whether hosted on Azure or on other cloud platforms.

Optimizing networking for IT workloads hosted in Azure IaaS requires an understanding of Azure virtual networks (VNets), address spaces, routing, DNS and load balancing.

Integrating your storage by using Microsoft cloud services gives you access to a broad range of services and cloud platform options

Hybrid cloud uses compute or storage resources on your on-premises network and in the cloud. You can use hybrid cloud as a path to migrate your business and its IT needs to the cloud or integrate cloud platforms and services with your existing on-premises infrastructure as part of your overall IT strategy.

Building a reliable application in the cloud is different than building a reliable application in an enterprise setting. While historically you may have purchased higher-end hardware to scale up, in a cloud environment you must scale out instead of scaling up. Costs for cloud environments are kept low through the use of commodity hardware. Instead of focusing on preventing failures and optimizing "mean time between failures," in this new environment the focus shifts to "mean time to restore." The goal is to minimize the effect of a failure.
