24/7 technical support

When using cloud infrastructure, several key advantages can be noted:

• Scalability — by this we mean the ability to adjust capacity in response to changing needs.
• The automation and self‑service system allows the client’s IT specialist to independently manage the volume of the service provided at any time, without having to contact technical support.
• Flexibility — the ability to quickly deploy new infrastructure or stop using it. In other words, it is the ability to use only the resources that are actually required to solve the problem. You can create two or more cloud infrastructures for yourself and stop using them independently.
• Economic benefit. You don’t buy the infrastructure, you rent it. This reduces the cost of purchasing, operating, and maintaining server equipment. You can read more about the economics of cloud infrastructure in the article “The Economics of the Cloud”.

VDS (Virtual Dedicated Server) is, in general, a standalone virtual machine. The Cloupard “Virtual Infrastructure” service provides significantly more capabilities than VDS and includes a variety of cloud services similar to traditional IT infrastructure in an office:

• Cloupard allows you to redistribute resources between virtual machines within the Cloud;
• Cloupard allows you to combine computers within a single cloud into one or more virtual private networks;
• Cloupard allows you to “transparently” combine private virtual and local networks via the VPN mechanism;
• Cloupard includes several additional important services, such as backup, monitoring, etc.

Cloupard operates two cloud platforms: one based on Hyper-V and the System Center product stack (VMM, DPM, OM, etc.); the other based on KVM/Proxmox and an OpenStack-related product stack. The service-management and billing control panel is developed in-house

We assume that your IT specialist or system administrator is familiar with the OSI model, the TCP/IP protocol stack, and the types of existing VLANs. If not, we recommend reviewing the relevant training materials. There is a good article about building networks in six parts: Networks for the very young http://habrahabr.ru/post/134892/
And the most convenient and fastest way to start working with us is to contact our Partners.

The definition from the Wikipedia well reflects Cloupard’s view on this issue: Infrastructure as a Service (IaaS, from the English “IaaS” or “Infrastructure-as-a-Service”) is provided as the ability to use cloud infrastructure to independently manage processing, storage, networks, and other fundamental computing resources. For example, the consumer can install and run arbitrary software, which may include operating systems, platform software, and application software. The consumer can control operating systems, virtual data storage systems, and installed applications, as well as have limited control over the set of available services (for example, firewall, DNS).
