Ans:- A CDN is a network of distributed servers that work together to deliver web content to users based on their geographic location, improving performance and reliability.

23. What is autoscaling in cloud computing?

Ans:- Autoscaling automatically adjusts the number of computing resources (such as virtual machines) based on demand, ensuring optimal performance and cost efficiency.

24. What is serverless architecture?

Ans:- Serverless architecture allows developers to build and run applications without managing servers. It relies on managed services and functions.

25. What is the difference between a cloud and a data center?

Ans:- A data center is a facility for housing computing equipment, while the cloud refers to the delivery of computing services over the internet.

26. What is cloud orchestration?

Ans:- Cloud orchestration is the automation of processes involved in provisioning, managing, and scaling cloud resources.

27. What is a cloud API (Application Programming Interface)?

Ans:- A cloud API is a set of rules that allows different software applications to communicate with each other in a cloud environment.

28. What is cloud security?

Ans:- Cloud security refers to the practices and technologies implemented to protect data, applications, and infrastructure in the cloud.

29. What is IAM (Identity and Access Management) in the cloud?

Ans:- IAM is a framework for managing and controlling access to cloud resources, defining who can do what in a cloud environment.

30. What is data sovereignty in the context of cloud computing?

Ans:- Data sovereignty refers to the legal and regulatory requirements that dictate where data can be stored and processed.

31. What is a cloud marketplace?

Ans:- A cloud marketplace is an online platform where users can discover, purchase, and manage cloud services and applications from various vendors.

32. What is the role of DevOps in cloud computing?
