Azure

Question 1

What is ACI?
Why Contenarized Application is better than standard?

Answer 1

[1] ACI - Azure Container Instance
Service that allows to run and orchestration containerized applications

[2] They are better than the standard because:
a) portability
b) consistency
c) Efficiency
d) scaling
e) costs

Question 2

What is AKS?

Answer 2

AKS - Azure Kubernetes Service
an open-source container orchestration system for orchestrating containerized applications. it used for deployment, scaling and managing applications

Question 3

[1] What are Azure Functions?
[2] What are benefits?

Answer 3

[1]
- Smallest compute service on Azure
- a single function to compute
- called or invoked via standard web address (URL)
- Runs once and stop
- Still it runs on some VM but it’s hidden from developer (No mainanence, No process, Nothing VM related)

[2] Benefits
- only runs when needed
- save money (you do not pay for functions if it is not used)
- Resilience (if your functions fails it does not affect functions)

Question 4

[1] What are the App Services?

Answer 4

App Services - fully managed Platform
It means that Storage, Network, Storage are handled or Managed by Azure. So you can focus on Business value and logic

WE have 3 categories:
- WebApps
-Web Apps for Containers
-API Apps

Question 5

What are Virtual Machines in Azure?

Answer 5

It is virtual hardware that you control. Spin up and down when needed.
Take advantage of the Azure tools.
Priced per hour with many configuration available

Question 6

What are Scale Sets?

Answer 6

Set’s of identical VM’s.
Scale sets automatically create and delete VM’s for your application.
Provides HA (high availability) and protects against server failures.

Azure virtual machine scale sets let you create and manage a group of load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide high availability to your applications and allow you to centrally manage, configure, and update a large number of VMs. With virtual machine scale sets, you can build large-scale services for areas such as compute, big data, and container workloads.

Question 7

Can Scale sets consists of virtual machines with different parameters and types?

Answer 7

NO!
When using scale sets for virtual machines, they need to be all machines of the same size and type. A common way you might hear this being referred to is as a “homogeneous” set, meaning “all the same type.” This is in comparison to “heterogeneous”, meaning “diverse types.”
