So after leaking (or not really leaking) from some of the sessions from re:Invent it seems that AWS have finally released the Client VPN
AWS Client VPN is a managed client-based VPN service that enables you to securely access your AWS resources and resources in your on-premises network. With Client VPN, you can access your resources from any location using an OpenVPN-based VPN client.
So instead of you having to provision a EC2 instance on your own and configure your own OpenVPN server - you can use this service
But pricing is outrageous…
$0.05 per AWS Client VPN connection hour
$0.10 per AWS Client VPN endpoint association hour
Assuming I would like to bring up a EC2 instance that would handle a 5 VPN connections and I leave the server running 24/7 for a month users connect for approximately 8 hours a day - 5 days a week
LEaving this service provisioned for the entire month would cost
0.10 * 750(hours in a month) = $75
0.05 * 5(people) * 8(hours) * 5 (days) * 4 (weeks) = $40
Total cost for one month - $115
If I were to roll my own on EC2
Using a t3.small instance (2vCPU/2GB ram) should be more than sufficient.
0.02 * 750 (hours in a month) = $15
OK - it is not comparing apples to apples - not by a long shot
Client VPN offers the following features:
Secure — It provides a secure TLS connection from any location using the OpenVPN client.
Managed service — It is an AWS managed service, so it removes the operational burden of deploying and managing a third-party remote access VPN solution.
Highly available and elastic — It automatically scales to the number of users connecting to your AWS resources and on-premises resources.
Authentication — It supports client authentication using Active Directory and certificate-based authentication.
Granular control — It enables you to implement custom security controls by deﬁning network-based access rules. These rules can be configured at the granularity of Active Directory groups. You can also implement access control using security groups.
Ease of use — It enables you to access your AWS resources and on-premises resources using a single VPN tunnel.
Manageability — It enables you to view connection logs, which provide details on client connection attempts. You can also manage active client connections, with the ability to terminate active client connections.
Deep integration — It integrates with existing AWS services, including AWS Directory Service and Amazon VPC.
Are all these extra features worth paying so much more for this managed service?
You are the only one that can answer this.
I am throwing the gauntlet out there - for someone to write the code that will enable the provisioning of a VPN Endpoint on demand - based on usage - which will make this service more cost effective.
