Implementing Azure Cloud Design Patterns

By: Oliver Michalski, Stefano Demiliani

Overview of this book

A well designed cloud infrastructure covers factors such as consistency, maintenance, simplified administration and development, and reusability. Hence it is important to choose the right architectural pattern as it has a huge impact on the quality of cloud-hosted services. This book covers all Azure design patterns and functionalities to help you build your cloud infrastructure so it fits your system requirements. This book initially covers design patterns that are focused on factors such as availability and data management/monitoring. Then the focus shifts to complex design patterns such as multitasking, improving scalability, valet keys, and so on, with practical use cases. The book also supplies best practices to improve the security and performance of your cloud. By the end of this book, you will thoroughly be familiar with the different design and architectural patterns available with Windows Azure and capable of choosing the best pattern for your system.

Connectivity is used to describe all processes for establishing communication channels, to or within the VNet. At present, we know three types of connectivity:

  • Internet connectivity
  • Connectivity between Azure resources (internal connectivity)
  • On-premises connectivity

Internet connectivity

All Azure resources that are connected to a VNet, have an internet connectivity in the outgoing direction by default. The private IP address used by the resource is translated into a public IP address by the Azure infrastructure via a Source Network Address Translation (SNAT) operation.

In order to be able to communicate with Azure resources over the internet in the incoming direction, you must assign a public IP address for the resource to your VNet.

Connectivity between Azure resources (internal connectivity)

Internal connectivity is the main area in the connectivity sector, because, without communication between Azure resources, no solution would work and ultimately, there would be no Azure network...
