Plesk is shipped with either monthly or yearly subscription. The lifetime perpetual license which offered back then has been retired. You can’t find this license anymore.
Supported Platform Environment
Starting from Plesk version 12 onwards, Plesk is shipped that support on 2 different platforms with 3 different editions – Plesk Web Admin, Plesk Web Pro, and Plesk Web Host.
You can install Plesk on 2 platform environments :
VPS / Cloud VM – Any of the virtualization platforms including VPS (KVM/Xen/OpenVZ), Parallels Virtuozzo Containers (4.6 above), VMWare, Hyper-V, Virtuozzo 6 & 7 for Linux and LXC (Docker).
Example providers – Amazon AWS, Digital Ocean, Alibaba Cloud, Vultr, Linode and any VPS plans offered by your hosting providers.
Dedicated Server – any bare metal physical dedicated server.
Example providers – any hosting providers you have leased a single dedicated server. If you run your own physical server on-premise, this is supported as well. Usually, this is the environment that you fully own all the resources on the server without sharing it with other users. The cost of running on this environment is also higher vs running on VPS/VM Cloud environment.
Plesk Operating System and Hardware Requirements
Plesk Hardware requirements
Aside from the platforms supported, Plesk best runs on the following software and hardware requirements for the best optimum performance.
Minimum Hardware Requirement.
- The minimum amount of RAM required for installing and running Plesk on Linux is 512 MB + 1 GB swap. On Windows – 2 GB of RAM.
- The minimum amount of free disk space required for installing and running Plesk is 10 GB on Linux and 30 GB on Windows
Recommended Hardware Requirement.
For an ordinary shared hosting environment, Plesk recommends that you have at least 1GB of RAM per 40 – 50 websites. So, 200 websites would imply Plesk hardware requirements of a minimum of 4GB. The recommendation is based on the following assumptions:
- On average, shared hosting servers see that about 10% of websites are active, in other words 10% of websites have a persistent level of traffic week in, week out
- 128MB of RAM will handle most websites. For example:
- 64MB for WordPress
- 64MB for Joomla
- 128MB for Drupal
- 128MB for Symfony
- A maximum of 1 to 3 simultaneous visitors for each website, with no more than 500 unique visitors per website on any given day
Websites with higher traffic (for example, 5 to 10 concurrent visitors and a total of 1,000 to 30,000 visitors per day) will require more RAM, in the range of 500MB to 1GB for each website. Also, note that Plesk hardware requirements mean that you need enough disk space for memory swapping.
The above are just assumption of requirements. Each implementation is different as the environment are different as the usages are different. It is always recommended for you to look into the growth of your websites traffic and customers in 6-12 months time so you can plan ahead for best optimization of your cost and ensure a smooth experience for your websites.

Which Plesk Edition Should I Use
Here are some few guidelines to ask yourself when evaluating which Plesk edition should you choose.
- How many domains will you be managing? For your own or for your customers?
- If you are offering web design and hosting services, will you be providing each of your customers their individual access to manage their website in Plesk?
- Do you need to create different kind of services and subscription plan with different features for your clients?
- Are you managing websites that runs on WordPress?
Answering these questions is useful for you to understand which edition to go with. If you are in doubt, you can always start with Plesk Web Admin Edition and upgrade to Web Pro or Web Host along the way. Upgrading does not need any reinstallation of your Plesk server or involve any migration. Same goes if you are downgrading to lower edition – example from Plesk Web Host to Web Pro.
Our client portal allows you to easily upgrade or downgrade your Plesk edition with the pro-rate on your bill. If you are migrating to the new server, you can also move the same license key to the new server by changing to the new IP address.
