Azure VMs Flashcards
What are machine scale sets?
Automatically manage and scale identical VMs according to demand.
What are machine availability sets?
VMs are grouped sets which have fault and update domains. Fault domains include all the machines that share physical infrastructure (power supply and network switch), while update domains contain all the VMs that share resources such that they can be rebooted at the same time. During maintenance, update domains are updated sequentially where each domain is given 30 minutes to reboot, before the next is updated.
What is serverless computing?
Server and infrastructure management is abstracted away. This means code can be run without thinking about infrastructure it is running on. The application is scaled automatically, and resources are allocated on demand meaning you only pay for CPU time.
What is Azure App Service?
Environment for hosting web application backend. Scale automatically, and require no infrastructure management or maintenance.
