aws ec2 hosting essentials for scalable, secure applications

What it offers

AWS EC2 provides elastic compute capacity so you can launch, resize, and retire servers on demand. Choose instance families, attach EBS volumes, and pick AMIs that match your stack. With security groups, key pairs, and IAM roles, access stays controlled without sacrificing developer velocity.

Getting started and right-sizing

Begin small, benchmark, then adjust instance type and storage. Use Auto Scaling with an Application Load Balancer to handle traffic spikes gracefully. Monitor CPU, memory, and disk with CloudWatch, and set alarms to act before customers notice. Mix On-Demand, Reserved, and Spot to balance cost and flexibility.

• Harden SSH, rotate keys, and restrict ports.
• Encrypt EBS and snapshots for backups.
• Use launch templates for repeatable builds.
• Store app configs in SSM Parameter Store.
• Enable detailed monitoring and logs.

For reliability, deploy across multiple AZs, keep images up to date, and test recovery often. EC2 remains a pragmatic core for cloud workloads when paired with thoughtful architecture and continuous observability.
