Questions & Answers

Q: How to create a VPC in AWS for production use?

To create a VPC for production, navigate to the VPC service in AWS, select 'Create VPC and more,' and configure it with public and private subnets across two availability zones. Attach route tables to the subnets, ensuring the public subnets have internet gateway access. This setup enhances security and availability for deployed applications.

Q: What is the purpose of using an Auto Scaling group?

An Auto Scaling group automatically adjusts the number of EC2 instances based on traffic demand, ensuring that applications have sufficient resources during peak times while minimizing costs during low demand. It enhances application availability and resilience by distributing instances across multiple availability zones.

Q: How does an Application Load Balancer work in AWS?

An Application Load Balancer distributes incoming application traffic across multiple targets, such as EC2 instances, in different availability zones. It operates at the request level (Layer 7), allowing it to route traffic based on specific request parameters, ensuring efficient load distribution and high availability of applications.

Q: Why are private subnets used in AWS architectures?

Private subnets are used to enhance security by isolating resources from direct internet access. Instances in private subnets can still access the internet via a NAT gateway, but external entities cannot initiate connections to them, reducing the risk of unauthorized access and protecting sensitive data.

Q: What is the role of a NAT gateway in AWS?

A NAT gateway enables instances in a private subnet to access the internet while preventing unsolicited inbound traffic from reaching them. It translates private IP addresses to a public IP address, allowing secure internet connectivity for updates or external API requests without exposing the instances directly.

Q: How does a Bastion host enhance security in AWS?

A Bastion host acts as a secure gateway for SSH access to instances in private subnets. By limiting SSH access to the Bastion host, organizations can enforce strict access controls, logging, and auditing, reducing the attack surface and enhancing the overall security of the AWS environment.

Q: What are Elastic IP addresses used for in AWS?

Elastic IP addresses are static IP addresses associated with your AWS account, which can be assigned to instances. They remain constant even if the instance is stopped or restarted, making them ideal for applications that require a fixed IP address for consistent communication or DNS configurations.

Q: How can load balancing improve application performance?

Load balancing improves application performance by distributing incoming traffic evenly across multiple instances, preventing any single instance from becoming overloaded. This ensures optimal resource utilization, reduces latency, and enhances the user experience by providing high availability and fault tolerance for applications.
