Aws EC2 launch types

AWS EC2 provides a range of launch types to suit diverse workload needs:

1. On-Demand Instances: This option lets you pay for computing capacity by the hour or second, with no long-term commitments or upfront costs. It is ideal for workloads that require flexibility and do not have predictable usage patterns.

2. Reserved Instances: By reserving capacity for 1 to 3 years, you can enjoy significant cost savings compared to On-Demand Instances. This option is suitable for workloads with steady usage or long-term commitments.

3. Spot Instances: Spot Instances allow you to bid on unused compute capacity, enabling you to run instances at a much lower cost. However, the instances may be interrupted if the Spot price exceeds your bid. Spot Instances are beneficial for workloads that can tolerate interruptions or have flexible start and end times.

4. Dedicated Instances: With Dedicated Instances, your instances run on dedicated hardware, providing isolation and compliance advantages. It is particularly suitable for workloads with strict compliance requirements or sensitive data.

5. Dedicated Hosts: This option enables you to book an entire physical server, offering full control over the underlying infrastructure. Dedicated Hosts maximize visibility and control over instance placement, making it ideal for licensing or regulatory requirements.

6. Scheduled Instances: If you have workloads with predictable schedules, Scheduled Instances allow you to reserve capacity for specific time windows. This option helps ensure availability for workloads that have fixed start and end times.

Each launch type comes with different pricing models and flexibility, empowering you to optimize costs and performance based on the specific characteristics and demands of your workloads.
