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.

Azure autoscaling

Once again, remember that availability can also be defined as the proportion of available objects (services) in the total number of objects (services). 

Immediately the question arises, does the availability rate increase as the number of available objects increases and if so, how do I achieve this? To answer the question, yes.

It increases the level of availability, and with the Azure autoscaling feature, there is also a platform-based way to do it.

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 rule-based number of instances.

In summary, while vertical scaling only influences the performance of your application, horizontal scaling can also affect the availability of the application.

Let's take a closer look at horizontal scaling. As I've already written, horizontal scaling is...
