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.

Scaling


Scaling is a complex topic because it can occur in two ways. With vertical scaling, I do not increase the number of instances of a service but migrate the service to the next higher-performance level. With horizontal scaling instead, I increase the number of instances.

The area scaling is covered on the Azure platform by the so-called Azure Autoscaling. Azure Autoscaling is one of the capabilities of the Azure Monitor service and works on a rule-based basis.

Let's take a closer look. I have already written that scaling is rule-based. But to be honest, that's just part of the reality. Before the autoscale engine can work, you need a complete configuration called Autoscale Settings, which consists of more than just rules.

Take a look at the following diagram:

What can you see?

The highest element of the configuration is the so-called Autoscale Settings. An Autoscale Setting is read by the autoscale engine to determine how to scale.

The Autoscale Settings contain one or more profiles. An...
