FAQ About AWS VPC Services.

Amazon EC2 (Elastic Compute Cloud) is a web service that provides resizable compute capacity in the cloud. It allows you to run virtual servers, called instances, on-demand.

EC2 instances are virtual servers that run applications on the AWS cloud. They can be provisioned with various configurations of CPU, memory, storage, and networking capacity.

EC2 pricing is based on several factors including instance type, region, and usage time. You can choose between On-Demand Instances, Reserved Instances, and Spot Instances to optimize costs.

EC2 instance types are categorized by their use cases and include families such as General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, and GPU Instances. Each type offers different performance characteristics.

Choosing the right instance type depends on your workload requirements, such as CPU, memory, storage, and network performance. AWS provides instance type recommendations based on use cases.

An Elastic IP address is a static IPv4 address designed for dynamic cloud computing. It allows you to associate a fixed IP address with your EC2 instances and manage IP address changes.

EC2 Auto Scaling automatically adjusts the number of EC2 instances based on your specified criteria, such as demand or performance metrics, to ensure optimal application performance and cost efficiency.

EC2 provides security features such as Security Groups for network access control, IAM roles for permissions, and Key Pairs for secure access to instances. Additionally, you can use AWS Shield and AWS WAF for advanced security.

An Amazon Machine Image (AMI) is a pre-configured template that includes the operating system, application server, and applications. It is used to create and launch EC2 instances with a specific configuration.

EC2 integrates with various AWS services such as Amazon S3 for storage, Amazon RDS for databases, and AWS Lambda for serverless computing. Integration enhances functionality and allows for comprehensive solutions.
