Azure VMSS Creation steps
- Rest of the steps remain as it is view our previous creation
- The difference will be in Upgrage Policy in Management Tab
- Watch classroom recording
Load Balancers
- When we scale number of vms we need to give an consistent ip address/name to the user, We will create Load Balancers as a consistent ip/name
- We have two types of load balancers
- Layer 4 load balancer
- At this layer it has knowledge of ip, protocol and port
- Layer 7 load Balancer
- At this layer it has all the knowledge of layer 4 and also url
- Suitable for multiple vmss where the routing decision is based on
- paths in url
- HTTP headers
- Hostname
Azure Lab setup
- Lets create a vmss with foundry and one more vmss with carpenter
- Now lets create a layer 7 lb in Azure (Azure Application Gateway) which does path based routing
- Generally load balancers will have health checks
- Azure calls a VMSS as a backend pool
- Watch classroom recording for steps
Exercise
- Try doing the same with AWS Application load balancer
