A Deep Dive into Amazon EC2

Amazon Elastic Compute Cloud (Amazon EC2) provides on-demand, scalable computing capacity in the Amazon Web Services (AWS) Cloud. Using Amazon EC2 reduces hardware costs, so you can develop and deploy applications faster.

Features of Amazon EC2

Amazon EC2 provides the following high-level features:

🌟 Amazon Machine Images (AMIs)

Preconfigured templates for your instances that package the components you need for your server, including the operating system and additional software.

🔑 Key Pairs

Secure login information for your instances. AWS stores the public key, and you store the private key in a secure place.

🌍 Regions and Zones

Multiple physical locations for your resources, such as instances and Amazon EBS volumes.

🔒 Security Groups

A virtual firewall that allows you to specify the protocols, ports, and source IP ranges that can reach your instances, and the destination IP ranges to which your instances can connect.

🛡️ Virtual Private Clouds (VPCs)

Virtual networks you can create that are logically isolated from the rest of the AWS Cloud. You can optionally connect these virtual networks to your own network.
