- Authentication (Easy Auth)

Scaling to Zero

ACA Limitations

Only Linux hosts 

Obviously no root access (shared environment)

Max 30 replicas

Pricing

10 million request / month => 3,2 USD
1 month ~ 2.6 mill seconds
5 requests per second (200 ms)

 

 

Active Usage (400.000 seconds)

​1 vCPU => 5,28 USD

1 GiB => 0.12 USD

Idle Usage (2.2 mill seconds)

​1 vCPU => 8,8 USD

1 GiB => 8,8 USD

TOTAL

26 USD

Pricing Comparison

Real world experience

• CPU + RAM limits hurts
• Pricing is not attractive for 24x7 containers
• Remember to implement probes (health, readiness, startup)
• In single revision mode, when redeploying you can experiencing cold starts
• Idle mode and scale to zero needs attention to work

Demo #3

Deploy with Azure CLI
