Cloud computing has transformed from a niche solution to a standard way of operating IT in businesses. The biggest question today may be which type of Cloud do you need: public, private or hybrid.
A lot of the momentum today revolves around hybrid. To help you better understand hybrid cloud, we’ll quickly look at the differences between the three types of Cloud.
1. Public Cloud
When most people hear the term Cloud,they think of the public cloud. It originally started with applications hosted over the Internet (Software as a Service), but today's public cloud can include applications, infrastructure, or data storage that are hosted by a third-party vendor. And, it's helpful to think of all three as separate.
2. Private Cloud
To the cynics, the “private cloud” is very similar to what we used to call a data center. The difference is that it uses virtualization, software, and automation to organize an infrastructure like the public cloud. This of course offers some of the flexibility that is found in the public cloud, but the big advantage of the Private Cloud is that it gives you more control over security, and data privacy.
3. Hybrid Cloud
It started as a marketing term, and so the definition of hybrid cloud can vary. Some see it as a parallel space for applications, data, and infrastructure.
For example, you store your data in the private cloud while running your application in the public cloud.
Others see it simply as the use of multiple cloud services, orchestrated to work together. The key point in this approach is that it moves away from a monolithic policy that compares public versus private cloud.
This specific policy is based on adaptability and the best service approach and that is why it seems to be quickly becoming the most popular Cloud.
