Application Services Extension (AS3)¶

Deploy a Simple HTTP Based Service¶

After this exercise, your simple HTTP based service should look like the below.

Tenant Name: MyWebService
Service Name: ServiceName
Application Name: AppName
Pool: HTTP based monitor
Pool members:
1. 10.1.20.11:80
2. 10.1.20.12:80

Building the AS3 Service Definition¶

Use the below example AS3 declaration as a template for configuring a generic HTTP service.
Replace the REST {{variables}} with an appropriate value.
Validate the JSON payload
- JSON linter such as JSONLint
- Native VS Code fuctionality
Save the configuration as it will be used later to reconfigure the service.
