As organisations are taking a step to modernize & digitalize their traditional workloads, the cloud has played one of the crucial roles in attaining scalability and performance. ‘Cloud first’ and ‘Cloud native’ now appear more frequently in enterprise growth and digital transformation strategies. The rise of cloud adoption has also made businesses move towards leveraging multi-cloud strategy.
The Flexera 2021 State of the Cloud Report suggest that
“enterprises have almost entirely embraced multi-cloud; 92 percent of enterprises have a multi-cloud strategy; 80 percent have a hybrid cloud strategy”.
What is Multi-cloud?Multi-cloud is a strategy where an organization leverages two or more cloud computing platforms to perform various tasks. It comprises public, private, and edge clouds to achieve the enterprise’s end goals. Generally, organisations do not want to depend on a single cloud provider and may choose to use resources from several providers to get the best benefits from each unique service. Multi-cloud is about exploiting the unique capabilities of different clouds, rather than going ‘all in’ with a single cloud.
Hybrid cloud vs Multi-cloudA hybrid cloud is not a multi-cloud, though a multi-cloud may include hybrid architecture. A hybrid cloud refers to the connection between a private cloud and a public cloud. This model is essentially used for securing sensitive data within an on-site cloud solution - or within a privately hosted cloud. A hybrid solution relies on a private data centre and leverages the advanced computing resources of a public cloud solution. On the other hand, a multi-cloud strategy can include a hybrid architecture but relies on more than one public cloud. An organization can select to store user data on-site, leveraging one cloud provider for IaaS and another for SaaS. Some cloud environments have tailored usage for specific use cases, which prompts IT stakeholders, to select a particular cloud service provider for specific business functions.
Benefits of Multi-cloud architectureThere are various reasons for enterprises to choose a multi-cloud environment. Each benefit associated can prove instrumental in establishing or maintaining a competitive advantage in today’s digital economy. Some of them are:
Challenges using Multi-cloudWith all the advantages gained with a multi-cloud approach, organizations should also be aware of its downsides. Some of the considerable challenges for multi-cloud strategy include:
Final thoughtsThe recent Gartner survey of public cloud users suggests that there will be a significant rise in multi-cloud adoption, therefore the enterprises need to consider both the advantages and challenges to fully benefit from the multi-cloud strategy. Careful planning and thought are required to achieve consistent and effective security & compliance and the use of additional tools and management platforms. Hence taking a step back now and developing a multi-cloud strategy will ensure organizations deliver the promised business benefits of the cloud as quickly as possible.
