FAQ

immers.cloud is a cloud platform through which the user can quickly and safely rent computing power in the required volumes. The allocated capacities are provided in the form of a Virtual machine (virtual server). The user gets isolated resources without overselling. The user gets access to the leased facilities via the Internet.

The immers.cloud team ensures the health and performance of the hardware and software of the cloud platform itself.

immers.cloud offers various tools for organizing a full-fledged infrastructure in the cloud: for example, self-creation of Virtual machines, automatic deployment of operating systems, creation of snapshots of virtual machines, scheduled backups, creation of virtual private networks. Management of all platform features is available through the web interface of the personal account or through the OpenStack API.

There are quotas and limits on the immers.cloud cloud platform:

Quotas — set amount of resources for new users.
Limits — are technical limitations that are set by the features of the platform architecture.
The quotas currently valid for your user are displayed by clicking on the user's name in the top menu.

Default quotas for all new users:

• vCPU — 16 cores,
• RAM — 128 GB,
• Number of volumes — 10 pcs,
• Number of pictures — 20 pcs,
• The total storage quota — 1600 GB,
• The number of VMs — 4 pcs.

The current quotas can be increased by making a request to support.

Limits applicable on the ims.cloud platform:

• The maximum number of GPUs for one VM is 4 pcs.

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.

You can change password on profile page: https://immers.cloud/user/profile/

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.

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.

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

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

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.

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.

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

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

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

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.

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

• CentOS 6, 7 and 8,
• Debian 8, 9 and 10,
• openSUSE 15 and 42,
• Ubuntu версий 16.04, 18.04 and 20.04,
• Windows Server 2019 Standard and Datacenter.

You can also choose a pre-configured image in the Marketplace.

It is possible. Own images are created through web-interface via uploading a file (glance-direct ) or specifying image URL (web-download).

Install NVIDIA drivers from the official archive:

wget http://us.download.nvidia.com/XFree86/Linux-x86_64/440.64/NVIDIA-Linux-x86_64-440.64.run
chmod +x NVIDIA-Linux-x86_64-440.64.run
sudo ./NVIDIA-Linux-x86_64-440.64.run

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

Currently each server has two 10GbE network interfaces.

Internet is connected to the VMs using 1Gb/s uplink. You can order extended or guaranteed bandwidth if needed via technical support.

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

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

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.

You can store files in the en.immers.cloud and perform operations with them. This requires separate software, the so-called S3 client.

To get started, you need to create an S3 user or connection details

Creating an S3 user and connection details
