Choosing the correct instance size for your workload is crucial for cost optimization. Avoid over-provisioning by selecting an instance size that meets your performance requirements without unnecessary overhead.

6.2. Using Reserved Instances

Reserved Instances (RIs) offer significant cost savings compared to on-demand instances. With RIs, you pay a one-time fee and receive a discounted hourly rate for a specified term (one or three years).

6.3. Savings Plans

Savings Plans provide even more flexibility and cost savings compared to Reserved Instances. With Savings Plans, you commit to a consistent amount of compute usage per hour for a one- or three-year term.

6.4. Spot Instances

EC2 Spot Instances allow you to bid on spare EC2 capacity, offering significant cost savings compared to on-demand instances. Spot Instances are ideal for workloads that are fault-tolerant and can be interrupted.

6.5. Stopping Unused Instances

Stopping unused EC2 instances can help you save money by avoiding charges for compute time. You can stop instances when they are not in use and restart them when needed.

6.6. Automating Start and Stop Times

You can automate the start and stop times of your EC2 instances using AWS Lambda and CloudWatch Events. This allows you to automatically start instances during business hours and stop them during off-hours, reducing your EC2 costs.

7. EC2 Use Cases and Examples

EC2 is versatile and can be used for a wide range of applications and industries. Here are some common use cases:

7.1. Web Hosting

EC2 is an excellent choice for hosting websites and web applications. You can easily deploy web servers like Apache or Nginx on EC2 instances and scale your infrastructure as needed.
