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.

Ans:- A cloud-native application is designed and built specifically to operate in the cloud, leveraging cloud services and taking advantage of cloud principles like scalability and resilience.
34. What is serverless computing cost model?
Ans:- In serverless computing, users are billed based on the actual usage of resources, rather than pre-allocated resources, resulting in a pay-as-you-go cost model.
35. What is a VPC (Virtual Private Cloud)?
Ans:- A VPC is a virtual network dedicated to a specific cloud account, providing isolated and secure networking within a cloud environment.
