A private cloud is an infrastructure that is always designed according to your needs after a thorough analysis of your needs carried out by our cloud specialists. A private cloud is particularly suited to large companies or websites with strict requirements in terms of capacity or security.
With a private cloud, you benefit from your own dedicated cloud environment. So, you do not share the cloud's hardware infrastructure with others, as you would with a public cloud. The advantage is that you benefit from more freedom and better flexibility. You can easily add extra resources and capacity without any downtime.
This is an example of a multi-tier network:
The web servers are in an isolated network that, in technical jargon, is called a DMZ (DeMilitarized Zone). Its aim is that the servers that are in direct contact with the outside world arrive in this zone.
This network is protected by a double firewall, one between the Internet and the internal network and the other one between the internal network and the underlying database and application servers. This way, there is a protection at 2 different levels.
This is an example of a private hybrid cloud: Here, we will combine a private cloud with an SQL cluster based on dedicated hardware. This is ideal with databases with extremely heavy loads. For such heavy applications, virtualisation is not always the best solution.
Thanks to the clustering technology, both nodes are actively used and high availability is also guaranteed.
In this scenario, we will spread the platform over 2 different sites. Firewalling and load balancing are also redundantly spread over both data centres. Here, the resources from both sites can always be used.
If a disaster happens in 1 of both data centres, the other data centre will temporarily process all the traffic.
