If your goal is an architecture that scales endlessly without software-imposed connection ceilings, you have two primary paths: clustering OpenVPN Access Server or transitioning to OpenVPN Community Edition. Strategy 1: Clustering OpenVPN Access Server

If the standard subscription model doesn't fit your needs, here are the three most common paths forward: 1. OpenVPN Community Edition (The True Unlimited Option)

Ideal for rapid deployment, allowing you to pay for the license directly through your cloud provider, often with hourly or annual pricing options.

You can purchase multiple software license keys and activate them on one server. The system adds the capacities together to increase your total allowed concurrent connections. Risks of "Cracked" Unlimited Licenses

Scaling to an "unlimited" number of users is only half the equation. The solution must also be performant and secure at that scale. OpenVPN Access Server is equipped with features that ensure it excels in both areas.

Do not trust any "lifetime unlimited" reseller or cracked installer. When it comes to your network’s security gateway, legitimate licensing is not an expense – it is insurance.
