Answer:
A VPC is a logically isolated section of a public cloud where you can launch resources in a virtual network that you define. It’s crucial for security and control, allowing you to define your own IP address ranges, subnets, route tables, and network gateways. This isolation ensures your resources are separate from other cloud users.

Question 8

How do you troubleshoot a performance issue with a cloud application?
Answer:
I would start by checking cloud monitoring tools like AWS CloudWatch or Azure Monitor for CPU utilization, memory usage, network latency, and disk I/O. Then, I would review application logs for errors or unusual patterns and inspect database performance. Gradually, I would narrow down the potential bottleneck, perhaps even scaling resources if necessary.

Question 9

What is serverless computing, and have you worked with it?
Answer:
Serverless computing allows you to run code without provisioning or managing servers; the cloud provider dynamically manages server allocation. Yes, I have experience with AWS Lambda and Azure Functions, using them for event-driven processing, backend APIs, and automating operational tasks. It’s great for reducing operational overhead and scaling on demand.

Question 10

Explain the concept of high availability in the cloud.
Answer:
High availability in the cloud ensures that your applications and services remain operational even if a component fails. This involves distributing resources across multiple availability zones or regions, using load balancers, auto-scaling groups, and implementing robust disaster recovery plans. The goal is to minimize downtime and provide continuous service.

Question 11
