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

Key Pairs

Link

You need to create your first key pair on the page /keypair/. Using this cryptographic pair, you can connect to Linux virtual machines or decrypt passwords for Windows machines. After that you can create a VM instantly.

Images

Link

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.
Link

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

Link

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.

Volumes

Link

After creating the Attachment of Volume to the Virtual Machine, make sure that the status of Volume has changed to in-use. After that, use the built-in Computer Management application, Storage devices / Disk Management section to activate and assign letter to the Drive.

Link

To expand a Volume, click the + icon on the right side of Volumes page.

Snapshots

Link

Shut down the virtual machine using the Stop option in the action drop-down menu. Use the Create Snapshot option and wait for the preparation of the Snapshot, making sure it receives the ACTIVE status.

Networks

Link

Currently each server has two 10GbE network interfaces.

Link

Internet is connected to the VMs using 1Gb/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.

Windows

Link

Go to Server Manager > Add Roles and Features Wizard then select "Features" on the left hand side, then finally check "Wireless LAN Service" and click next/install. Finally, restart.

Payments and Charges

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.

Linux

API

Link

Yes, we do provide API for Cloud Management. Connection and documentation on actual version available here: /api/.
