Multi-cloud deployment is the use of two or more cloud computing systems at the same time. This deployment might use public clouds, private clouds or hybrid clouds. Multi-cloud deployments have the goal to offer redundancy in case of hardware/software failures and avoiding the vendor lock-in. It uses the two or more cloud computing platforms at the same time. A company might want to use the private cloud for confidential information and use the public cloud for a web application. Also, the company may want to fail over to another cloud in case of problems with their primary cloud platform.
There are some third party software tools available for managing multiple cloud deployments. It usually involves a company selecting more than one cloud service provider and putting different workloads into each platform or shifting the workload and volumes to multiple cloud services.
There are major benefits to architecting multi-cloud deployments to the companies to start with multiple cloud providers instead of just one. Different cloud providers may fulfill different roles that are optimized to certain applications. An individual cloud is great for high-volume data transfer, developers or other stakeholders may request cloud operations that do different things.
The other benefits of multi-cloud include building an initial infrastructure that is easy to maintain, scale and manage. When companies go into the single-cloud platform, it can be a little difficult to build the same onto multi-cloud. With initially setting up the multi-cloud infrastructure it can be made scalable and hence can be beneficial in the future.
Multi-cloud deployment can also be very helpful from the cost perspective. It can be made available through on-demand service. When the company reaches the threshold, needs new services, a greater volume of data on demand, having more than one cloud provider option is a wise decision. This makes the multi-cloud deployment more favorable.
