Decrease the number of stages by making them into jobs - azure-devops

Question

I tried to create the below yaml pipeline config file. Can I get some help on reducing the number of stages in YAML pipeline. This is to reduce number of stages per domain.
name: '$(Date:yyyy.MM.dd)$(Rev:.rr)'
trigger:
branches:
include:
- master
- features/*
pool:
name: CustomPool
stages:
- template: templates\build.yaml
- template: templates\deploy.yaml
parameters:
Environment: 'dev'
IsEnabled: true
Domain: 'domainX'
ServerList:
- name: ServerX
restartIIS: true
- template: templates\deploy.yaml
parameters:
Environment: 'test'
IsEnabled: true
Domain: 'domainY'
ServerList:
- name: ServerY
restartIIS: false

Scenario 1: If you don't want to use stages, you can only use jobs in the main YAML and your template. There is a demo you can refer to.
azure-pipelines.yml
trigger:
- none
pool:
vmImage: ubuntu-latest
jobs:
- template: JobTemplate1.yml
- template: JobTemplate2.yml
- template: JobTemplate3.yml
JobTemplate1.yml
jobs:
- job: job1_1
steps:
- script: echo This is job1_1
- job: job1_2
steps:
- script: echo This is job1_2
In this example, each template has 2 jobs. Eventually you can see a total of 6 jobs running.
Scenario 2: If you want to use stages in your main YAML but just want to decrease the stages in your template, you can use only one stage and several jobs in your template.
azure-pipelines.yml
trigger:
- none
pool:
vmImage: ubuntu-latest
stages:
- template: template1.yml
- template: template2.yml
- template: template3.yml
template1.yml
stages:
- stage: Template1_Stage
jobs:
- job: Template1_Stage_job1
steps:
- script: echo This is Template1_Stage_job1
- job: Template1_Stage_job2
steps:
- script: echo This is Template1_Stage_job2
In this example, template1 has one stage and two jobs. Template2 has two stages, and each stage has one job. Template3 has one stage and one job. For your case, you can refer to template1.
