Could the organization survive if part or all of its information
were lost?
Just remember, RAID is not a backup solution. RAID protects against the loss of individual drives, but if data gets corrupted or deleted, RAID will replicate that corruption across all RAID stripes. Making backups on separate media is the best way to protect yourself against both "hard" and "soft" data loss.

The different types of "cloud"
------------------------------
Unfortunately "cloud" is a term which is overloaded in the industry. This course refers to cloud in the Infrastructure as a Service (IaaS) sense, not the hosted applications sense.
Unfortunately "cloud" is a term which is overloaded in the industry.
This course refers to cloud in the Infrastructure as a Service (IaaS) sense, not
the hosted applications sense.
There are currently two types of IaaS cloud being deployed. These are "public clouds", which are services such as Amazon's AWS, Rackspace's OpenStack based cloud offering or HP's OpenStack based cloud. There are a variety of companies of various sizes offering these public cloud services. These services are run in the hosting company's datacenter, and an administrator's access to the infrastruture is limited to launching and configuring virtual machines, normally through a web-based dashboard or an API.

These services are run in the hosting company's datacenter, and an
administrator's access to the infrastruture is limited to launching and
configuring virtual machines, normally through a web-based dashboard or an API.
The second type of cloud is "private clouds". These are conceptually similar to public clouds, but run in your own datacenter. The point here is that you retain complete control over the environment -- if some of your virtual machines need access to unusual hardware, or store data which you're unwilling to move offsite, then private cloud might be a good choice. The open source OpenStack system is often used to build these private clouds, and there are various vendors offering private cloud solutions, including RackSpace, Piston, and Canonical.
