To use Amazon EC2, you simply:

Select a pre-configured, templated Amazon Machine Image (AMI) to get up and running immediately. Or create an AMI containing your applications, libraries, data, and associated configuration settings.

Configure security and network access on your Amazon EC2 instance.

Choose which instance type(s) you want, then start, terminate, and monitor as many instances of your AMI as needed, using the web service APIs or the variety of management tools provided. Determine whether you want to run in multiple

locations, utilize static IP endpoints, or attach persistent block storage to your instances.

Pay only for the resources that you actually consume, like instance-hours or data transfer.

AWS Storage Gateway is a set of hybrid cloud services that gives you on-premises access to virtually unlimited cloud storage. Customers use Storage Gateway to integrate AWS Cloud storage with existing on-site workloads so they can simplify storage management and reduce costs for key hybrid cloud storage use cases. These include moving backups to the cloud, using on-premises file shares backed by cloud storage, and providing low latency access to data in AWS for on-premises applications. To support these use cases, Storage Gateway offers four different types of gateways ?Amazon S3 File Gateway, Amazon FSx File Gateway, Tape Gateway, and Volume Gateway ?that seamlessly connect on-premises applications with cloud storage. Moving data to the cloud for advanced AWS Cloud storage capabilities and caching data locally for low-latency access gives you the best of cloud and on-premises. Applications connect to the service through a virtual machine or gateway hardware appliance using standard storage protocols, such as NFS, SMB, and iSCSI. The gateway connects to AWS storage services, such as Amazon S3, Amazon S3 Glacier, Amazon S3 Glacier Deep Archive, Amazon FSx for Windows File Server, Amazon EBS, and AWS Backup, providing storage and data management for files, volumes, snapshots, and virtual tapes in AWS. The service includes an optimized and efficient data transfer mechanism, with bandwidth management and automated network resilience, and provides a consistent management experience using the AWS Console on-premises and in the AWS Cloud.
