Each user of the service "virtual private cloud" gets at the disposal of the domain - their own virtual space to create projects and users. A project in this case refers to a collection of objects and resources that can be accessed by a user: the virtual machines, disks, networks, and others.
Resources and Quotas
At the beginning of the cloud becomes the owner of the resources (memory, core CPU, disk space), and distributes them among its projects, thereby setting limits to create a variety of objects. At any time you can reallocate resources between projects, or to give up some of the resources.
Access Management
The owner of the virtual private cloud can create users and set permissions for them to projects. This feature is intended for corporate clients, as well as resellers, create a project and provide access to external users on a commercial basis.
For each project, a direct link through which you can gain access to its resources, without registering in our panel. In the near future we plan to implement the ability to customize and design changes to the external user panel.
Flexible Creation of Virtual Machines
Our service allows the user to create just such a machine, what he needs, not forced to choose from several pre-defined configurations (flavor), as is often done in the clouds, implemented on the basis of Openstack. At any time, you can increase each parameter of the virtual machine (for example, the amount of RAM), the whole thing with the other.
Network Connections
Virtual machines can be connected to the network in various ways. The owner can either rent the clouds, we selected a public subnet (the same way as it is done for dedicated physical servers), or use the mechanism of "floating» IP-addresses (floating IP).
In the latter case the machine receives an address from the private network, which may be assigned a public address from the common pool. At any time, you can decouple the IP-address from one machine and attach it to another. Converting external addresses to internal and vice versa by means of a virtual router.
Machine can also be connected to an isolated local area network (for example, if it is used as a backend and immediate access to the Internet it is not necessary). If necessary, such a network can connect to the router and assign some machines external IP-addresses - for example, for ease of maintenance.
Download Images
The new cloud is supported by a set of images for the most common distributions of Linux (such as Ubuntu, Debian, CentOS, OpenSUSE), as well as Windows Server 2012. In addition to the standard agent cloud-init, is present in the images we have created an agent that implements a number of useful features: reset password on request from the control panel, the static network configuration (if there is no DHCP), and SSH-control keys. In addition, customers can upload their own images to the project of virtual machines. Supported image formats are used in systems virtualization Virtualbox, KVM, VMware, and the format of Amazon EC2.
Hard Disks
The machine can be connected to any number of hard drives. Wheels can be created as a blank, and on the basis of images. Supported by technology snapshots. If you allow the possibility of the operating system in a virtual machine disks can be connected and disconnected "on the fly".
Other Possibilities
Among other things, it supports the ability to add SSH-key, the graphical console generation RC-file to work with customers and other console. In the near future the emergence of many new features - stay tuned!
