AWS VPN

Securely and privately access your cloud resources with either an AWS Site-to-Site VPN, Accelerated Site-to-Site VPN, or Client VPN connection.

AWS Site-to-Site VPN features

Accelerated Site-to-Site VPN

When you connect an on-premises location to the AWS cloud, Accelerated Site-to-Site VPN will route your VPN traffic to the closest AWS edge location. Accelerated VPN improves the performance of your Site-to-Site VPN connections by reducing the distance over which data is being shared on the internet and leveraging instead the reliability and performance of the AWS global fiber network. Accelerated Site-to-Site VPN is ideal to connect business-critical locations with your global network, both on premises and in AWS. VPN acceleration will incur additional charges from utilizing both AWS Site-to-Site VPN and AWS Global Accelerator.

Secure connectivity

AWS Client VPN uses OpenVPN, which utilizes a TLS encrypted control channel to negotiate the data channel parameters. The data channel is SSL based, but adds additional safeguards (such as HMAC, hashing, and x.509 certificates).

High availability

With AWS Site-to-Site VPN you can create failover and CloudHub solutions with AWS Direct Connect. CloudHub enables your remote sites to communicate with each other, and not just with the VPC. It operates on a simple hub-and-spoke model that you can use with or without a VPC. This design is suitable for customers with multiple branch offices and existing internet connections who would like to implement a convenient, potentially low-cost hub-and-spoke model for primary or backup connectivity between these remote offices.

Customization

AWS Site-to-Site VPN offers customizable tunnel options including inside tunnel IP address, pre-shared key, and Border Gateway Protocol Autonomous System Number (BGP ASN). In this way, you can set up multiple secure VPN tunnels to increase the bandwidth for your applications or for resiliency in case of a down time. In addition, equal-cost multi-path routing (ECMP) is available with AWS Site-to-Site VPN on AWS Transit Gateway to help increase the traffic bandwidth over multiple paths.

Network Address Translation (NAT) Traversal

AWS Site-to-Site VPN supports NAT Traversal applications so that you can use private IP addresses on private networks behind routers with a single public IP address facing the internet.

Monitoring

AWS Site-to-Site VPN can send metrics to CloudWatch to provide you with greater visibility and monitoring. CloudWatch also allows you to send your own custom metrics and add data points in any order, and at any rate you choose. You can retrieve statistics about those data points as an ordered set of time-series data.

AWS Client VPN features

AWS Client VPN provides a fully-managed VPN solution that can be accessed from anywhere with an Internet connection and an OpenVPN-compatible client. It is elastic, and automatically scales to meet your demand. Your users can connect to both AWS and on-premises networks. AWS Client VPN seamlessly integrates with your existing AWS infrastructure, including Amazon VPC and AWS Directory Services, so you don’t have to change your network topology.

Authentication

AWS Client VPN will authenticate using either Active Directory or certificates. Client VPN integrates with AWS Directory Services, which connects to your existing on-premises Active Directory, so it does not require you to replicate data from your existing Active Directory to the cloud. Certificate-based authentication with Client VPN integrates with AWS Certificate Manager to easily provision, manage, and deploy certificates.

Authorization

AWS Client VPN provides network-based authorization so you can define access control rules that limit access to specific networks, based on Active Directory groups. 

Secure connectivity

AWS Client VPN uses the secure TLS VPN tunnel protocol to encrypt the traffic. A single VPN tunnel terminates at each Client VPN endpoint and provides users access to all AWS and on-premises resources.

Connection management

You can use Amazon CloudWatch Logs to monitor, store, and access your log files from AWS Client VPN connection logs. You can then retrieve the associated log data from CloudWatch Logs. You can easily monitor, conduct forensics analysis, and terminate specific connections, while staying in control of who has access to your network.

Compatibility with your employees' devices

AWS Client VPN is designed to connect devices to your network. It allows you to choose from OpenVPN-based client, giving employees the option to use the device of their choice, including Windows, Mac, iOS, Android, and Linux-based devices.
