Multi Cloud

What is Multi Cloud?

Multi cloud is a cloud computing model where an organization distributes assets over at least two clouds from different public cloud or private cloud providers. Multi cloud involves strategically using several cloud solutions from multiple suppliers. This method diversifies cloud infrastructure, reducing risk and vendor lock-in. It lets organizations choose the finest services and pricing models from several providers to maximize performance and efficiency. Multi cloud deployments reduce the effect of provider outages and interruptions. It also allows workload deployment across cloud environments to meet requirements and regulatory compliance.

What is the difference between multi cloud and hybrid cloud?

There are variations between multi cloud and hybrid cloud service deployment and management:

Multi cloud:  Multi cloud refers to using multiple cloud computing and storage services within a single network architecture. Workloads are distributed among public clouds, private clouds, or both under this technique. Each cloud service provider has different features, prices, and geographies. Organizations use multi cloud to prevent vendor lock-in, increase redundancy, maximize performance, and use services from different providers. 

Hybrid cloud: This computing environment allows data and programs to be exchanged between public and private clouds. A hybrid cloud system utilizes a combination of private and public cloud architectures to host resources and workloads. The hybrid cloud architecture offers flexibility, scalability, and security by keeping sensitive data and important apps on-premises and using the public cloud for other workloads.

In conclusion, hybrid cloud integrates public and private cloud environments to build a cohesive architecture, whereas multi cloud uses numerous cloud services from different providers.
