What is a managed cloud server? Print

  • 2

A Cloud Server instance is similar to a Virtual Private Server (VPS) however the resources of a Cloud Server are provided by many powerful computers whereas a VPS typically resides on a single Dedicated Server.

A Cloud Server floats above a farm of powerful dedicated servers so resources can be locked in and guaranteed.

To create a VPS we split up one computer (server) and make it look like, for example, 20 servers. Each of these VPS then can be accessed as a stand alone computer that have their own operating system.

To create Cloud Servers we set up many computers and use their resources to make Cloud Servers each with their own operating system.

With a traditional VPS performance can be degraded when the dedicated server it lives on becomes very busy or if there is a hardware failure.

With a Cloud Server resources are run dynamically across many servers in a network which ensures that all resources are available at all times. 

With a Cloud Server instance one can be reliably guaranteed of a specified amount of power and speed that is available at all times (even if one of the computers in the farm has a hardware error).

What do you mean by a "managed" Cloud Server?

A Cloud Server is a virtual computer. It behaves very much like a Dedicated Web Server. (A dedicated web server in this context is a big computer that is used for hosting many websites.)

With a dedicated web server a systems administrator needs to configure it so that it displays websites efficiently, fast, and to many people all over the world. 

However there is not only performance and load to consider but also security!! All dedicated web servers, VPS and instances that are connected to the internet are under constant attack, not only from "the Russians" but from "the Chinese", "the Americans" and, well, the "the whole hacker world"!

If one looks at the logs of any web server, even if it has been connected to the internet only for a few minutes, attacks begin to appear from everywhere by "bots". These bots are a little bit like those nasty flying robots in the movie "The Matrix" in that they just keep coming and coming. As a system administrator one needs to identify these bots and swat them away, all the while letting legitimate website viewers in and delivering them the goods! (The web pages, images and other media) The system administrator also needs to let "good bots" through i.e. the Google Bot that frequently comes along to appraise a website and decide where and how it will be ranked in the Google search engine. 

"Bad bots" will try and sneak though cracks in the armour of the server. If the bots get in they can cause havok, steal data, send spam, and take over the server, sometimes secretly, and nearly always for nefarious purposes! So a system administrator must manage the server, in this case a cloud server, to ensure that the bad bots and bad actors can't break in! This means keeping software and security frameworks, firewalls etc up to date!

System administrators, usually in tandem with the Network Operation Centre (NOC), must also have methods to deal with "Denial of Service (DOS) attacks". These attacks are when a bad actor decides to swarm a server with thousands of bots all at once causing a server to fall to its knees and stop working.

Another important system administrator task is to maintain rolling backups of the server. These backups are critically important! If a cloud server instance fails for any reason, be it because of some type of attack, a mistake from a website programmer, or because of a computer hardware failure it can be a miserable situation. But with a selection of backups to choose from a system administrator can bring up an entire cloud server instance (and all attached website/s) in a short time. 

With a computerjazz.net Managed Cloud Server all of these tasks are something that you don't need to think about. With two decades of server administration we will make sure that your cloud server continues to do what it is supposed to do: deliver your website pages and content reliably and quickly. If anything at all goes wrong the cloud server can be restored in a short amount of time. Backup restorations are not expected but are sometimes required. When they are needed it is usually a mission critical function: "Everything is broken. Nothing works!! Do you have a backup?"

"Yes, indeed we do!"

A well managed cloud server is a very powerful platform that can be used to reliably host enterprise websites for the long term.
