immers.cloud overview

Link

immers.cloud is a cloud GPU platform that lets you host virtual servers equipped with powerful NVIDIA GPUs: ideal for everything from cloud gaming and 3D rendering to machine learning and running large language and generative AI models.

We offer pay-as-you-go-billing, meaning you pay only for the exact time your server is running.

The Sign-up process takes seconds: no long forms, no approvals, no waiting. Create your first GPU instance and start working within minutes of registration.

Our GPU servers are used for:

  • AI and neural network training;
  • Machine learning research and scientific computing;
  • 3D animation and visual effects rendering;
  • High-end cloud gaming;
  • Large-scale data and video processing.

When you host a GPU server, you get full, dedicated access to the hardware. Everything is managed through an intuitive web dashboard or via OpenStack API.

The immers.cloud platform enforces quotas and limits:

  • Quotas — predefined restrictions applied to new users.
  • Limits — technical constraints determined by the platform’s architectural design.

Your current quotas are displayed when you click on your username in the top menu.

Default quotas for all new users:

  • vCPU — 16 cores;
  • RAM — 128 GB;
  • Number of volumes — 10;
  • Number of snapshots — 20;
  • Total storage quota — 1,600 GB;
  • Number of Virtual Machines — 4.

Current quotas can be increased upon request — simply contact technical support.

Platform limits on immers.cloud:

  • Maximum number of GPUs per single Virtual Machine — 8
     

Registration

Link

An individual need to finish registration, confirm the email address and recharge the personal account. Money is most often credited without a delay.

Organization representative needs to finish registration, confirm the corporate email address, add the organization and pay the first invoice. A copy of the payment can be sent to payments@immers.cloud for an accelerated transfer of funds.

VM

Link

Use PuTTY for Windows or ssh for Linux. Use IP аddress of the VM as host address. For modern cloud images there are typical logins: ubuntu, debian, fedora, opensuse, cloud-user. Use pem or ppk file downloaded after creation of specified Key Pair.

Link

To shut down the Virtual Machine, use the Stop option of the Actions drop-down menu on the Virtual Machines list page or on the page of a individual Virtual Machine.

Billing of CPU and RAM of a virtual machine stops only when using mentioned method of shutting down the virtual machine.

Link

It is possible Choose RESIZE action on the VM list page.

Link

It is possilbe. Use RESIZE option in action menu of the VM list page.

Link

Yes, you can. When VM setup and software installation will be finished stop the VM and create snapshot. When snapshot creation will be completed you can create multiple Virtual Machines from that Snapshot.

Link

Ordered Virtual Machines are created automatically at any time of the day. Typically, the process planing and hosting a virtual machine, deploying an image and the cloud-init stage are completed in a few minutes.

Link

We don't have mininal rental period. Use VM as long as you need it.

Link

Currently one Availability Zone is available located in data center in Moscow, Russia.

Link

Use run command with keys: Windows + R, then type and run gpedit.msc

Find Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment and Enable option “Use the hardware default graphics adapter for all Remote Desktop Services sessions”.

Configurations

Link

Our servers are equipped with Intel® Xeon® Gold 2nd, 3rd, and 5th Generation processors:

  • Cascade Lake 6240R and 6248R are used on servers with GPUs: V100, RTX 2080 Ti, RTX 3080, RTX 3090, A10, and T4;
  • Ice Lake 6336Y are used on servers with GPUs: A2, A5000, RTX 4090, A100, and H100;
  • Sapphire Rapids 6448Y are used on servers with GPUs: RTX 5090;
  • Emerald Rapids 6548Y+ are used on servers with GPUs: H200.
Link

At immers.cloud, you get access to 13 powerful NVIDIA GPUs. From flagship AI accelerators to high-performance graphic cards for rendering and gaming, we cover it all.

No need to buy or maintain expensive hardware. Run your projects in the cloud with full performance on demand.

For large-scale neural network training and inference, choose our latest models: Tesla A100, H100, and the new H200. These are the foundation of major generative AI, scientific research, and data science projects.

With massive memory capacity, high bandwidth, and next-gen tensor cores, they deliver record-breaking performance. They also handle long-context workloads with ease.

Need rendering, 3D visualization, or gaming? Go with RTX series GPUs: from the proven RTX 2080 Ti to the top-tier RTX 5090.

They excel in Blender, Cinema 4D, Unreal Engine, Redshift, Octane, and other render engines. All support NVENC hardware encoding: perfect for streaming and 4K+ video processing.

For lighter tasks like voice, image, and video processing, Tesla T4, A10, A2, and L4 are ideal.

These are efficient, cost-effective, and perfect for low-latency GPU virtual desktops and services. Stable, reliable, and affordable.

All powered by the cloud. No baremetal. Just results.

Link

For rendering and machine learning tasks, it is important that the amount of RAM is greater than the total amount of VRAM, so for a configuration with four A10s (each have 24GB of video memory), we recommend configurations with at least 96 GB of RAM.

For gaming, we recommend configurations with GPU, 8 CPU cores, 16 GB of RAM and a 160 GB disk.

Streaming configurations are usually less memory or disk intensive. For disk-intensive tasks, we recommend SSD drives (Volume + Volume SSD-based instance type) or Local, otherwise use the cheapest HDD-based Volume + Volume instance type.

Images

Link

More than 100 images with pre-installed operating system are available:

  • Ubuntu 16.04, 18.04, 20.04, 22.04 and 24.04

or use images with the drivers installed: Ubuntu 16.04.6 or Ubuntu 18.04.4 with CUDA.

Networks

Link

Currently each server has two 10GbE network interfaces.

Link

Internet is connected to the VMs using up to 20Gb/s uplink. You can order extended or guaranteed bandwidth if needed via technical support.

Link

Technically number of networks and adressess are not limited. On practice personal quotes will apply. To increase personal Quotes contact technical support.

Payments and Charges

Link

There are 2 prepaid tariffs available for long-term rental of VMs:

  • prepayment for 30 days with a 25% discount
  • prepayment for 60 days with a 50% discount%

This means that you can rent a VM with a 25% or 50% discount by prepaying the full rental period at once. The full rental cost will be immediately chardged from the balance, so the required amount of funds must be on the balance before creating a VM.

Prepaid tariffs are available only for VMs with GPU. Prepaid tariffs may not be available for all GPUs at different times. The relevance of the currently available prepaid tariffs is reflected on the page: https://en.immers.cloud/prices/.

For a VM running according to the prepaid tariff, expenses in the "Purchases" section will be added once per day. On the VM page you can see the number of remaining prepaid days.

Important: You cannot change flavor for a VM created according to the prepaed tariff

Prices

Link

For SHUTOFF Virtual Machines, spendings are made for the actually reserved resources - SSD space and HDD volumes, in accordance with their volume, external IP addresses and personal VLANs, reserved PCI-Express devices (only for servers with GPUs). vCPU and RAM are not charged.

We provide GRID vWS/vApps licenses for Tesla cards.

Tesla A10, T4 and V100 support work in TCC and WDDM modes. By default GRID driver use WDDM mode. To change mode execute command with administrator privileges:

nvidia-smi -g {GPU_ID} -dm {0|1}
-dm 0 - WDDM Mode
-dm 1 - TCC Mode

RTX and GeForce cards works only in WDDM mode.

In case of manual installation of GRID drivers you must set License Server parameters:

Immersion

Link

Immersion cooling is currently the most cost-effective way to cool high‑density IT equipment. Unlike a traditional air‑cooled data center, our system uses only 5% of the total energy for cooling.

Our IT hardware operates without fans, reducing power consumption by up to 30% right out of the box. Each of our 42U racks can accommodate up to 160 GPUs with a power load of up to 80 kW per rack.

Immersion cooling keeps components at optimal temperatures, ensuring stability and enabling higher clock speeds for every CPU and GPU.
