Hi,

Uptime is obviously one of the most important thing alongside with the good network, when it comes to web hosting services. We can see that most providers "claim" "99.9999% uptime" or even "100% uptime". However, the fact is that most of them just don;t have the proper infrastructure to offer such services?

My questions is "Are you familiar with the hardware and software technologies that provide both High Availability and Fault-Tolerance both on a infrastructure (provider's side) and on the service (client side) level?".

Uptime is certainly important, but those guarantees aren't really guarantees of uptime, rather what the provider's response will be if they fall beneath those numbers - like credits for downtime. If a provider continually falls less than 99.9% uptime, a market correction normally takes place and they'll starting experiencing increased customer churn. To answer your question, yes.

Cluster technology can provide 99,9% uptime. In this technology servers are connected into computing cluster and insure each other.

Cluster is old technology now and has bee replaced by cloud. Their is really nothing clustering offers over cloud.

We use KVM on top of Openstack and never had hardware failure ... yet

Hi @HostingMachines, "Cluster is old technology now and has bee replaced by cloud" is a very bold statement and very untrue. The principles of clustering are in place with any "Cloud computing" infrastructure technology. The only difference between is that a "Cluster" refers to a physical computing, while "Cloud" is about virtualized computing infrastructures. So technically, clustered computing systems, as concept and as a technology are the in core of any Cloud Computing system.
