- Learn the Terminology: Familiarize yourself with common AWS terminology, such as instances (virtual servers), S3 buckets (data storage containers), and security groups (virtual firewalls).
- Launch Your First Service: Use the console to launch an EC2 instance or create an S3 bucket. These are great starting points for deploying applications or storing data.
4. AWS Compute Services
AWS offers several compute options, allowing users to run their applications in the cloud without worrying about managing physical servers.
Here are some of the key compute services you should know about:
Amazon EC2 (Elastic Compute Cloud)
Amazon EC2 is one of AWS’s foundational services. It allows users to create and configure virtual machines, known as instances and is great for running web applications, databases, and other workloads.
- On-Demand Instances: Pay for compute capacity by the hour without long-term commitments.
- Reserved Instances: Get significant discounts in exchange for committing to a one-year or three-year term.
- Spot Instances: Use instances to save up to 90% of unused EC2 capacity. However, note that these can be interrupted if AWS needs the capacity back.
AWS Lambda
AWS Lambda is a serverless computing service that allows users to run code without provisioning or managing servers. You only pay for the compute time used, and it’s ideal for tasks that don’t need a dedicated server running all the time.
