Public, private, hybrid or community: Which cloud fits YOU?

There are several critical decisions you need to make as your organization takes its first step into cloud computing:

  1. Whether to make use of one of the public cloud services offered by vendors like Amazon, MS Azure & Google; or


  2. Build a private cloud in your own datacenter(s) or possibly in Co-Lo(s) and decide whether to operate your own or use managed services vendors; or


  3. Combine private & public cloud with a hybrid cloud: Build the cloud infrastructure on-prem then use public cloud for DR, HA & burst-out; or


  4. The fourth option is to join or even start a community cloud: A group of common-industry organizations that agree on a model to connect and share virtual resources.

You may find that one cloud model works best for one project but not another. It’s about finding the best balance of Speed, cost, utilization & compliance.
