Multi-Cloud, the latest Buzz in Cloud Hosting

Multi-Cloud, the latest Buzz in Cloud Hosting

Cloud based platforms are continually evolving into more and more complex arrangements. This is partly due to the fact that businesses around the world now demand top-of-the-range cloud services to be combined into optimal solutions. The concept answering this demand is known as 'multi-cloud'.

But what exactly is multi-cloud? It is without a doubt far more complex than hybrid cloud, which essentially pairs public and private clouds. Multi-cloud basically adds additional clouds into this mix. This may, for instance, include two, three or more public IaaS providers and a private PaaS, as well as on demand security and/ or management systems from varying public clouds, accounting based on private use, and so on.

This is, at the end of the day, the way cloud computing has been heading for several years now. Solutions are created more and more from intricately designed sets of high-class public and private cloud services. The process is very much like the elaboration of distributed internal systems in previous years, where varying technologies were integrated into a solution to meet specific requirements. Multi-cloud is basically the same, just using cloud technologies instead.

So why should anyone care about multi-cloud? While the buzz-word itself carries little clout, the key, in essence, is the architecture of cloud computing, which now typically integrates multiple private and public cloud providers. Projects involving just one or two providers/ technologies are far and few between, with most projects now including at least six or more options.

The core concepts of multi-cloud reality to bear in mind are as follows:

Considering the complexity and distribution of multi-clouds, governance and security have to be considered more carefully and in great detail
Considering the number of potentially moving parts, multi-clouds may develop certain resiliency issues that will have to be dealt with
To meet requirements and provide value, the right providers for multi-cloud services must be selected

In essence, it is of extreme importance to take the lessons the building of complex distributed systems have taught and apply them to multi-cloud deployments. Complexity is invariably driven by integration and must be carefully planned and managed, with no substitute for well designed architecture.

Bearing the core concepts mentioned above in mind and approaching multi-cloud in a well-considered, disciplined manner will certainly serve to offer ever more useful, intricate solutions to the ever increasing needs of today's, as well as the future's, ever increasing complicated business needs.
