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.
Figure 5.14 – Virtual machine scale set resource type
We will click to open it. In the Settings section, you will find the Scaling option.
Figure 5.15 – The Scaling settings
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.
