Ec2 — AWS Solutions Architect Associate Practice Questions
Amazon EC2 (Elastic Compute Cloud) is the foundational AWS compute service that provides resizable virtual machines, called instances, running in the cloud. The exam covers instance lifecycle management, pricing models (On-Demand, Reserved, Savings Plans, Spot), placement groups, and how EC2 integrates with storage (EBS, instance store), networking (VPC, security groups), and IAM. You need to understand when to choose EC2 versus managed services like Lambda or ECS based on workload characteristics. EC2 concepts appear across nearly every domain of the exam because most architectures include or compare against it.
