What to know about private cloud!

Before considering cloud-based data protection, it is important to first understand the basics of cloud, which can sometimes be foggy (at best). With trade magazines and publications defining the "cloud" in a number of different ways, IT managers and executives are often confused about the true meaning of the term; however the recent maturation of cloud-based services has helped the definition become more focused.

 In a nutshell, there are two main tSTORServer Rocksypes of cloud-based data protection services: public and private. The public cloud is where data is on a shared infrastructure. In a private cloud, data is on dedicated infrastructure and the owners of that data share no part of it with others. There are variations of the public and private cloud, including combinations of the two that result in a "semi-private cloud," but for the sake of clarity, we will stay away from that topic.

In data protection, there are some popular configurations to consider. The first is disaster recovery to a private cloud, which assumes an existing solution is onsite and has a backup copy and perhaps an archive copy. Usually this involves a system with disks and/or tape that keeps the data protected for a set duration of time. It then assumes that users want to automate disaster recovery to another location. Customers who need this cloud offering typically want to move away from a tape solution or have not yet installed a disaster recovery technology.

Full data protection recommends an off-site second backup copy or a disaster recovery copy. Disaster recovery to a private cloud could be to a secondary site owned by a customer (at another site or building) or could be hosted by a managed service provider (MSP) who provides data protection as a service. If users go to a third party MSP for disaster recovery and wish to have it in a private cloud (no shared infrastructure), it can become cost prohibitive due to the MSP needing dedicated resources assigned only to that user.

What is the difference between customer’s hosted private cloud and MSP hosted Private cloud?  Lets drill into that for a moment
