AWS EC2
Explore the fundamentals of AWS EC2 including instance types, networking options, purchasing methods, and enhanced networking devices. Understand how to configure security groups, use Elastic IPs, and automate instance setup with user data to effectively manage and scale cloud applications.
Introduction to EC2
Elastic Compute Cloud (EC2) is one of the most popular AWS services. Introduced in 2006, it was one of the first services offered by AWS. EC2 is the most basic and essential service for all the AWS certification exams.
EC2 is an IaaS. We primarily use it to provision virtual servers for our applications on AWS. EC2 also has services like Elastic Block Store (EBS), Elastic Load Balancing (ELB), and Auto Scaling groups (ASGs), which are used in various combinations with the EC2 instances to form different types of architectures. One of the most important benefits of cloud computing is the on-demand availability of services, which EC2 provides.
EC2 features
Let’s look at some important features of the AWS EC2 service.
- EC2 instances can operate Linux, Mac OS, and Windows operating systems (OS).
- EC2 supports on-demand provisioning of servers. We can provision and terminate EC2 instances at any time. AWS will only charge us for the type of instance we use and the exact time we use it.
- Users can reserve EC2 instances for long
