Businesses can leverage EC2 for big data processing using frameworks like Apache Hadoop and Spark. The ability to spin up clusters quickly allows organizations to analyze large datasets efficiently.

6. Backup and Disaster Recovery

EC2 can be used as part of a backup and disaster recovery solution. Organizations can create snapshots of their instances and store them in Amazon S3, ensuring data safety and quick recovery in case of failures.

7. Gaming

Game developers can utilize EC2 for hosting multiplayer game servers, providing a flexible and scalable infrastructure that can adjust to varying player loads.

Pricing

Amazon EC2 offers various pricing models that cater to different usage patterns and budgets:

1. On-Demand Pricing

• Pay-as-you-go: Users pay for compute capacity by the hour or second, depending on the instance type.
• No long-term commitment: This model is ideal for applications with unpredictable workloads.

2. Reserved Instances

• Cost Savings: Users can save up to 75% compared to on-demand pricing by committing to use EC2 for a one- or three-year term.
• Flexible Payment Options: Reserved Instances come with various payment options, including all upfront, partial upfront, and no upfront.

3. Spot Instances

• Discounted Rates: Spot Instances allow users to bid on unused EC2 capacity, often at significantly lower prices than on-demand instances.
• Ideal for Flexible Workloads: This model is suitable for applications that can tolerate interruptions.

4. Savings Plans

• Flexible Pricing: Users can commit to a consistent amount of usage (measured in $/hour) for a one- or three-year term in exchange for lower prices on EC2 usage.
• Broader Coverage: Savings Plans apply to any EC2 instance regardless of region, instance family, operating system, or tenancy.

Comparison with Other Tools

When comparing Amazon EC2 with other cloud computing services, several unique selling points and advantages stand out:
