Hybrid Cloud Approach-The days of defining cloud computing as just “the cloud” are over. The definition of “cloud” has changed and fractured. Cloud services can now be deployed as public, private or both. One of the more recent models, the hybrid cloud, mixes public and private cloud services.
Most recently, Google rolled out a beta version of its hybrid model, Google Cloud Platform. That highlights the emerging trend of trying to strike a balance between the modern public cloud and the on-premises model. At first, hybrid cloud may sound like another marketing term. Further complicating the problem is that the definition varies, making it even more hazy.
That said, we’re going to dig into it, sift through the marketing speak and, hopefully, unravel the mystery of one of the more recent shifts in cloud services. If you haven’t, you can read our other guides to catch up on big trends in the cloud, such as the one on what is edge computing, in which we talk about fog computing and the network edge.
What Is Hybrid Cloud?
Hybrid cloud is something of a catchphrase. The term is misleading because it was coined by vendors and providers. That term gets even muddier and more vague as major providers, such as Amazon, Google and Microsoft, all approach hybrid cloud differently.
To put it simply: hybrid cloud is a mash-up of public and private cloud deployments, operating as separate entities, with the ability to manage them as one. Hybrid cloud can get more complicated than that — a lot more complicated. That’s in layman’s terms, though. There are multiple ways to build a hybrid cloud, each offering its own pros and cons.
We won’t attempt to detail them here because we could go on about them forever. The good news is that major Infrastructure-as-a-Service providers are making hybrid cloud easier by extending their public infrastructure to better integrate with private, on-premises services (read our piece on the best IaaS providers).
