A Developer's Guide to Building Resilient Cloud Applications with Azure

By: Hamida Rebai Trabelsi

Overview of this book

To deliver software at a faster rate and reduced costs, companies with stable legacy systems and growing data volumes are trying to modernize their applications and accelerate innovation, but this is no easy matter. A Developer’s Guide to Building Resilient Cloud Applications with Azure helps you overcome these application modernization challenges to build secure and reliable cloud-based applications on Azure and connect them to databases with the help of easy-to-follow examples. The book begins with a basic definition of serverless and event-driven architecture and Database-as-a-Service, before moving on to an exploration of the different services in Azure, namely Azure API Management using the gateway pattern, event-driven architecture, Event Grid, Azure Event Hubs, Azure message queues, FaaS using Azure Functions, and the database-oriented cloud. Throughout the chapters, you’ll learn about creating, importing, and managing APIs and Service Fabric in Azure, and discover how to ensure continuous integration and deployment in Azure to fully automate the software delivery process, that is, the build and release process. By the end of this book, you’ll be able to build and deploy cloud-oriented applications using APIs, serverless, Service Fabric, Azure Functions, and Event Grid technologies.

Exercise 3 – scaling an Azure Service Fabric cluster

There are three mechanisms to scale a Service Fabric cluster.

Manual scaling

The first one is to manually specify the number of node instances that you want. So, let’s navigate to the VM scale set resource. We need to select the resource group that includes the Service Fabric instance. Then, select Virtual machine scale set as the type, as presented in the following screenshot.

We will click to open it. In the Settings section, you will find the Scaling option.

As shown in the preceding screenshot, the default option is Manual scale but you can specify the number of node instances. In the figure, we have 5 node instances, but we can set it to 20, for example. After saving this option, the VM scale set will increase from 5 to 20 instances.
