105 - Multi-cloud benefits, challenges and adoption

The journey started from the cloud to arriving on the multi-cloud. Nowadays, every IT department in an organization is heading towards the multi-cloud era. Let’s first get our heads clear,


• What is multi-cloud?

• What is a hybrid cloud?


As we are hearing, these two terms are sometimes interchangeable.


So multi-cloud is where an organization uses the cloud services from two or more cloud providers, such as the Oracle Cloud, AWS, Azure, and Google Cloud.


A hybrid cloud is where the organization uses on-premises services, or “private cloud,” and a few from any of the cloud providers – public clouds, such as the Oracle Cloud, AWS, Azure, and Google Cloud.




Now the first question that comes to mind is, why multi-cloud? A few areas to think of…


• Vendor lock-in (in other words -multiple cloud vendors lock in)

• Data center availability – this is also linked to the compliance requirement that you need to have an in-country data center

• Utilize the best services from the cloud vendor, who specializes in certain services.

• Low latency requirements for certain applications and that vendor doesn’t have a data center in that region.

• Price optimization

• By accident, they opted for multi-cloud (within organizations, the different departments opted for different cloud vendors).

• Resilience (I need to have a backup site with other cloud providers)


The multi-cloud strategy brings several benefits to organizations, however, implementing a multi-cloud also brings challenges, few to mention:


• Compatibility

• Increased complexity

• Security

• Interconnection between different cloud providers

• The learning curve for the IT teams (to learn about different cloud providers)

• Cost estimation and reporting.

• Cloud management

• Multi-cloud architecture
