With those three steps you’ve got all you need to be able to setup an autoscaling group in AWS that can register new nodes as you need to scale up and scale down! In the near future, we’re also hoping to open source the Terraform module that we use for this at Mixmax so others can use it as well!Įnjoy working on problems that you can't copy-paste a solution for? Drop us a line.I am using VPN (Endpoint Security, Check Point) to establish connection to the Firebird 2.1 database from IBExpert on my computer.

# Unzip the downloaded zip file to access the `vault` binary. # Retrieve the Vault binary for our platform. As such, we were able to use Vault in order to retrieve three sensitive credentials that each node needs during its initial boot sequence (which we run as the instance’s user-data). Here at Mixmax, we use Vault for storing secrets and auditing access to them. Bootstrapping the necessary dataīootstrapping data is a difficult problem, or rather, it’s a difficult problem if you don’t use a secret management system. Let’s walk through how we solved the previous problems in the user data template file that every new Pritunl node starts with.

In addition to that, due to the manual nature of adding new nodes to the cluster, Pritunl can’t easily autoscale out of the box. While deploying an HA Pritunl configuration is much easier than other systems, it’s still a manual process. Pritunl also has built in auditing of user activity as well as visualization of the load on your deployment.Īll of this sounds great, so what’s the problem? The problem

It’s also more secure than OpenVPN’s alternative, because Pritunl will create temporary, authorized download links for users to retrieve their personal credentials, whereas in normal OpenVPN deployments credentials have to be shared in some manner (via USB, email, etc). It also has single sign on, which makes getting users set up with their credentials much easier than with OpenVPN. We love Pritunl at Mixmax - it’s relatively simple to setup and it’s built to be highly available. Today we’re going to talk about autoscaling Pritunl - our preferred VPN solution at Mixmax. To ensure these issues never arise, VPNs either need to be oversized or they need to be able to autoscale - they must be highly available (HA). When there is even the slightest issue though, everyone notices - accessing internal portals takes an appreciable amount of time due to large latency spikes, teams have difficulty interacting on private resources due to flakey connections. When they work well, no one knows that they’re there. Every security minded organization knows the need for a secure manner to access their private networks, but even in this modern “Infrastructure as a Service” world, VPNs often have to be built manually.
