Choosing cloud hosting: where to start?
Dear Gabriele, after experimenting with Samara coworking and other projects, we finally decided to start writing something for Habra in the core of our business, that is hosting, servers and related technologies. To start I would like to write about popular among developers of cloud resources and to compare the major players in this market.

The word “cloud” is well known by all site owners. Cloud technologists are provided as a service has access to resources (memory, CPU, storage devices, etc.), without specifying where exactly at what point resources are resources.
"Cloud" suggests the possibility of providing resources with high guarantee of their availability. In other words, if the hardware resources of physical computers in the cloud go down or are disabled, cloud as a whole can continue to function (in some cases without significant loss of efficiency), or even to restore the healthy state automatically ("self-healing" self-healing).
In the case that you need to select the cloud provider, the following is a list from which to start. All of them are suitable for the site hosting.

The most budget of all the cloud providers for the masses, Digital Ocean (hereafter DO) provides a minimum but sufficient instrumentation for a fully automatic management of resources. Typical time to create and launch a new virtual machine is less than one minute.
DO provides the ability to create "snapshots" (snapshots), backup your servers (currently free service). A snapshot captures the state of a virtual machine at the time of its creation — then you can return the car in this state of recovery (unlike the launch of the new machine, the restore may take longer). The can be transferred to another user — so you can configure the virtual machine "turnkey".
Optional: customers DO a large knowledge base with standardized recipes, setting up virtual machines for specific needs, specific software.
In American data centers, you can get internal IP address for the virtual machine. The speed of the internal grid reaches 1Gbps, allowing, for example, to form a virtual machine cluster structure.
Since August 2014 DO has to support the protocols of the IPv6 family.
The API allows you to automate all the actions with virtual machines (all that is available from the browser interface, available through the API).

Introduction
The word “cloud” is well known by all site owners. Cloud technologists are provided as a service has access to resources (memory, CPU, storage devices, etc.), without specifying where exactly at what point resources are resources.
"Cloud" suggests the possibility of providing resources with high guarantee of their availability. In other words, if the hardware resources of physical computers in the cloud go down or are disabled, cloud as a whole can continue to function (in some cases without significant loss of efficiency), or even to restore the healthy state automatically ("self-healing" self-healing).
