To use Amazon EC2, you simply:
Amazon EC2 bare metal instances provide your applications with direct access to the processor and memory of the underlying server. These instances are ideal for workloads that require access to hardware feature sets (such as Intel® VT-x), or for applications that need to run in non-virtualized environments for licensing or support requirements. Bare metal instances are built on the Nitro system, a collection of AWS-built hardware offload and hardware protection components that come together to securely provide high performance networking and storage resources to EC2 instances. Bare metal instances are EC2 instances and thus offer the same robust security, reliability, capacity elasticity, and support for different operating systems and software packages as other virtual EC2 instances. You can also use bare metal instances with AWS services such as Amazon Virtual Private Cloud (VPC), Elastic Block Store (EBS), Elastic Load Balancing (ELB) and more.
With a single API call, Amazon EC2 Fleet lets you provision compute capacity across EC2 instance types, Availability Zones, and purchase models to help optimize scale, performance and cost. You can specify how much On-Demand and Spot capacity to launch via EC2 Fleet. You can also define which instance types you prefer and whether to scale capacity based on cores, instances or memory. Read FAQs and AWS blog to learn more. Now you can access EC2 Fleet capabilities via Amazon EC2 Auto Scaling to provision and automatically scale compute capacity across EC2 instance types, Availability Zones, and purchase options in a single Auto Scaling Group.

Reserved Instances provide you with a significant discount (up to 75%) compared to On-Demand instance pricing. In addition, when Reserved Instances are assigned to a specific Availability Zone, they provide a capacity reservation, giving you additional confidence in your ability to launch instances when you need them.
For applications that have steady state or predictable usage, Reserved Instances can provide significant savings compared to using On-Demand instances. See How to Purchase Reserved Instances for more information.
