It is acknowledged easily that the development and production data must be kept separate. In this context, having multiple clouds of data is more significant to prioritize security and information. Besides that, you are able to assign multi-level access controls and benefit from the different clouds.
Mention not to say, you get organizational resilience and agility.
Literally, the term multi means - many; i.e. Multi-Cloud refers to use of more than a single cloud.
The enterprises are able to use varied cloud service providers for software services [SaaS] or the infrastructure services [IaaS].
This kind of usage arose as a necessity to choose specific services from the public cloud service providers to avail the best of each, gain all the benefits, avoid dependency on a private or a single cloud service provider.
Firstly, use of cloud came into the scenario.
Most of the organizations had the vision to place their workloads on the cloud [either private or the public], wherein the hybrid cloud architecture stepped into as an attractive option as the enterprises were left with choices.
The compelling cloud platforms developed by Microsoft and the Google formed the best alternative to Amazon Web Services and the Enterprises readily wanted to take the choice. The other service providers like the IBM, Oracle, or the HP Enterprise also started to have their footprints in the cloud computing.
As all these were viable public cloud options, the enterprises started benefitting from these service providers and began to mix them. They adopted them as formal architectural processes and also the “shadow IT” wherein certain groups of the company used the public cloud without the knowledge of others in the IT. The shadow IT made them pick different public clouds spontaneously.
Whatever, the may be, today, most of the enterprises are managing the multi-cloud infrastructure.
The enterprises are managing the multiple clouds as if they are a single cloud with the help of cloud management platforms [CMPs] or the cloud service brokers [CSBs] tools.
In brief, the IT organizations are able to optimize a coordinated mix of cloud-based technologies. The departments and the user communities as well are able to adapt well to the next-generation applications and workloads gaining flexibility.
For instance: the e-commerce digital business uses one cloud to tune maximum scalability and another cloud to use harness the large pools of storage.
Multi-cloud allows a business to choose the most appropriate location to deliver their apps from or consume them as a service. I see many Enterprises opt for a primary cloud provider initially but with an eye on not getting locked in, contractually, technically or via skills. Having the tools that allow you consume multi-cloud is often an afterthought once a level of cloud adoption has been reached. (Often DevOps are in the cloud already and IT playing catch up). It needs to be part of the initial planning IMHO. Then the big challenge is delivering end to end services across multiple clouds without creating silos. (Governance, Performance, Compliance, Security, Analytics.....), says
Roger Dickinson, Technical Solutions Architect at Cisco.
Another found enterprises running an average of 1.8 public clouds and 2.3 private clouds, an indicator that multi-cloud strategies are quickly gaining traction.
It goes without any doubt, that multi-cloud is nothing but the collection of best of expectations and gift for every level of the enterprise. Indeed, when you have the option to choose the best services for best performance of the organization, there is no doubt if it takes the lead in the upcoming days.
