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.

Distributed cloud: organizations want to have their own decision and choice for the cloud resources that they want to have. It could be multiple public clouds, or even an Oracle cloud@customer, an AWS outpost, etc. The point is that services will be like a public cloud and managed, and governed by the public cloud vendor.

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
