System requirements for remote development
Remote Development is still in development. The system requirements might change over time, we will work to support more types of systems in the future. Systems that don’t meet the requirements may work with Remote Development, yet we will not be able to support issues that might arise along the way.
Depending on the size of your project, ensure that the system to which you are connecting meets the following requirements:
Minimal requirements
For a complete list of system requirements, refer to Install IntelliJ IDEA.
Recommendations
For larger projects, add more CPUs and RAM. The load average indication in the IDE will tell you if an upgrade would be advisable.
Enabling Swap is recommended. Even on cloud instances.
Local SSD storage.
Not supported
Single-board computers such as Raspberry Pi. To run your code on a Raspberry Pi, check out remote interpreters or remote debugging, and similar features.
Shared web hosting services. In such hosting environment, there might be numerous websites that coexist on a single server owned and operated by the hosting provider. All the websites hosted on this server are required to share its resources, such as bandwidth, memory, and computing power. These resources are distributed evenly among all the accounts on the server, which become quite limited.
The remote development support is not possible in such cases due to the following reasons:
In addition to the SSH port, there must be a free port on the server for the IDE backend to reside. Shared web hosting typically does not permit the occupation of additional ports.
There might be restrictions on running third-party software.
Shared web hosting imposes limitations on user CPU usage.
