You are looking to create a fault-tolerant colocation site for your servers at a cloud provider. Which type of cloud provider would you be searching for?

If you were looking to create a fault-tolerant colocation site as a cloud provider, you would be searching for an infrastructure-as-a-service (IaaS) provider. This would allow you to install your own operation system and applications. A platform-as-a-service (PaaS) solution is similar to running applications in the cloud, where the platform supports some level of programming language, such as Python, Ruby, or Visual Basic. Software-as-a-service (SaaS) is probably the most common, since services such as email, contract management, and many others are hosted by SaaS providers. Backup-as-a-service (BaaS) is popular today because it can allow for the long-term storage of data offline after a backup has completed.
