Multi Cloud environments are associated usage of two or more cloud services to minimize the risk of widespread data loss or downtime due to a localized component failure in a cloud computing environment.
The strategy behind this implementation is simple- Let us suppose a failure has occurred in hardware, software or infrastructure of in-house data center. Then as a part of business continuity planning, let us assume that a user has opted for a cloud service, so that as soon as the in-house data center goes down, the cloud service can act as a failover.
Now, what if, the cloud service also experiences an outage during the time of failover?
This is where a multi-cloud strategy helps in acting as a failover and keeping the continuity of data/service alive. It also helps in improving overall enterprise performance by avoiding vendor lock-in and using different infrastructures to meet the needs of diverse partners and customers. Additionally, a multi cloud approach can not only offer the hardware, software and infrastructure redundancy necessary to optimize fault tolerance, but it can also steer traffic from different customer bases or partners through the fastest possible parts of the network.
In this architectural usage, some organizations use a public cloud to make resources available to consumers over the internet. But a few of them also depend on private cloud for data security and privacy concerns.
Sometimes a hybrid cloud also uses a mix of on-premises, private cloud and third party public cloud services with orchestration between the two platforms. A hybrid cloud gives businesses greater flexibility and more data deployment options.
