5. What is Azure Kubernetes Service?

6. What is Azure Kubernetes service
AKS is an open-source fully managed container orchestration service that became
available in June 2018 and is available on the Microsoft Azure public cloud that
can be used to deploy, scale and manage Docker containers and container-based
applications in a cluster environment.
This offers Serverless Continuous and Continuous Deployment Experience.

7. What it offers is?
● End to End Deployment
● Scalability
● Availability

8. Evolution of the Software Development
Some right questions and some Changes in the Infrastructure used.

9. On premises had some of the problems
1. Which OS works better?
2. What is the size of server should i buy?
3. Are my server in secure location?
4. How often should I patch my server?
5. How can I increase Server utilization?
6. How do I architect my application?
7. How do I deploy the new code on my server?
8. What is plan be for the disaster and the Fault tolerance?
9. When should I take the Backup?
10. How can I increase server utilization?
11. What storage is needed?
12. How often should I patch my servers?
13. How can I dynamically configure my app?
14. Which packages should be on my server?
15. servers for my business needs? And many more

10. IaaS had some problems
1. What is the right size of servers for my business needs? How can I increase
server utilization? How many servers do I need? How can I scale my app?
2. How often should I patch my servers? How often should I backup my server?
Which packages should be on my server?
3. How do I architect my application?
4. How do I deploy new code to my server? Which OS should I use? Who
monitors my App?

11. PaaS
1. What is the right size of "servers" for my business needs?
2. How can I increase "server" utilization?
3. How many "servers" do I need?
4. How can I scale my app?
5. How do I architect my application?

13. Serverless is always about
How do I architect my application?

14. The cloud simplified
1. Computer
2. Storage
3. Network

15. There were different models to it
Application
Architecture
Application
Infrastructure
Deployment
Or
Packaging
Waterfall
Agile
DevOps
Scrum

16. Monolithic v/s SOA v/s Microservice

• Containers are isolated but share OS
• Increase the compute density and
memory utilization

18. What is Kubernetes?

19. Need for Kubernetes?
1. Container Communication
2. Appropriate Container Deployment
3. Careful Container Management
4. Enable Autoscaling
Just Refer : https://kubernetes.io/

22. UI
CLI
API Kubernetes Master
NODE 1
NODE 2
NODE - N (any number of
nodes can be created)
Everything that we
can think about the
container will also be
done from the
kubernetes here.

23. Kubernetes Master
Everything that we
can think about the
container will also be
done from the
kubernetes here.we
also can talk about
replication controller
and service

24. Some Terms for the Defintion
1. Master
2. PODS
3. Nodes
4. Replication Controller
5. Service

25. Working of the Azure Kubernetes Service?
So they are the service that you use for managing the compute resources for the
application that has been deployed.
Every time an API calls there is a different service that requires compute service
thus scaling and load shifting is also taken care from the AKS clusters.

28. So basically lift and shift operation is also taken care

29. Uses of AKS
● Existing apps can be easily migrated to Kubernetes.
● Microservices-based application deployment and administration made easier
● DevSecOps is simple to incorporate.
● On-demand deployment and control of IoT devices
● AKS is used to train machine learning models.

30. Use cases of the AKS

31. So let's build some Clusters for any application
