What is AWS Outposts?

AWS Outposts is a fully managed service that extends AWS infrastructure, services, APIs, and tools to customer premises. By providing local access to AWS managed infrastructure, AWS Outposts enables customers to build and run applications on premises using the same programming interfaces as in AWS Regions, while using local compute and storage resources for lower latency and local data processing needs.

An Outpost is a pool of AWS compute and storage capacity deployed at a customer site. AWS operates, monitors, and manages this capacity as part of an AWS Region. You can create subnets on your Outpost and specify them when you create AWS resources such as EC2 instances, EBS volumes, ECS clusters, and RDS instances. Instances in Outpost subnets communicate with other instances in the AWS Region using private IP addresses, all within the same VPC.


You cannot connect an Outpost to another Outpost or Local Zone that is within the same VPC.

For more information, see the AWS Outposts product page.

Key concepts

These are the key concepts for AWS Outposts.

  • Outpost site – The customer-managed physical buildings where AWS will install your Outpost. A site must meet the facility, networking, and power requirements for your Outpost.

  • Outpost capacity – Compute and storage resources available on the Outpost. You can view and manage the capacity for your Outpost from the AWS Outposts console.

  • Outpost equipment – Physical hardware that provides access to the AWS Outposts service. The hardware includes racks, servers, switches, and cabling owned and managed by AWS.

  • Outposts racks – An Outpost form factor that is an industry-standard 42U rack. Outpost racks include rack-mountable servers, switches, a network patch panel, a power shelf and blank panels.

  • Outposts ACE racks – The Aggregation, Core, Edge (ACE) rack acts as a network aggregation point for multi-rack Outpost deployments. The ACE rack reduces the number of physical networking port and logical interface requirements by providing connectivity between multiple Outpost compute racks in your logical Outposts and your on-premise network.

    You must install an ACE rack if you have five or more compute racks. If you have less than five compute racks but plan to expand to five or more racks in the future, we recommend that you install an ACE rack at the earliest.

    For additional information on ACE racks, see Scaling AWS Outposts rack deployments with ACE racks.

  • Outposts servers – An Outpost form factor that is an industry-standard 1U or 2U server, which can be installed in a standard EIA-310D 19 compliant 4 post rack. Outpost servers provide local compute and networking services to sites that have limited space or smaller capacity requirements.

  • Service link – Network route that enables communication between your Outpost and its associated AWS Region. Each Outpost is an extension of an Availability Zone and its associated Region.

  • Local gateway (LGW) – A logical interconnect virtual router that enables communication between an Outpost rack and your on-premises network.

  • Local network interface – A network interface that enables communication from an Outpost server and your on-premises network.

AWS resources on Outposts

You can create the following resources on your Outpost to support low-latency workloads that must run in close proximity to on-premises data and applications:

Resource type Racks Servers

Amazon EC2 instances

Yes Yes

Amazon ECS clusters

Yes Yes

Amazon EKS nodes

Yes No
Database and analytics
Resource type Racks Servers

Amazon ElastiCache nodes (Redis cluster, Memcached cluster)

AWS IoT Greengrass Yes Yes
Amazon SageMaker Edge Manager Yes Yes


You can choose from a variety of Outpost configurations, each providing a combination of EC2 instance types and storage options. The price for rack configurations includes installation, removal, and maintenance. For servers, you must install and maintain the equipment.

You purchase a configuration for either a 1-year or 3-year term and can choose from three payment options: All upfront, Partial upfront, and No upfront. If you choose the Partial upfront or the No upfront option, monthly charges will apply. Any upfront charge will apply 24 hours after your Outposts rack is activated, that is, when your Outposts rack capacity becomes available for launching instances. For more information, see:
