Multi-Cloud & Hybrid Cloud Concepts

In short

You'll hear 'we're multi-cloud' in interviews and on LinkedIn. Sometimes it's a smart strategy, often it's an accident of history. Knowing the trade-offs helps you ask the right questions.

Multi-cloud uses more than one cloud provider (for redundancy, avoiding lock-in, or best-of-breed services); hybrid cloud combines cloud infrastructure with on-premises systems — both add real complexity for real trade-offs.

The mascot carries a small bag between a wooden home almirah and two different bank lockers.

Think of it like this

Home almirah and two bank lockers

Some families keep jewellery in the home almirah and in lockers at two different banks. Safer if one bank has a problem, but now you track three keys, three sets of rules and lots of trips. Hybrid is home plus bank; multi-cloud is two banks.

Watch it happen

Two different ideas

Multi-cloud

Two or more public clouds
Avoid lock-in or use best-of-breed
Double the skills and tooling

Hybrid cloud

Own data centre plus public cloud
Keeps regulated or legacy systems on-site
Needs secure links between them

Both add real complexity. Choose them for a clear reason, like regulation or a key service, not because it sounds impressive.

The big ideas

What you need to know

Lock-in is a trade-off

Managed services save time but tie you to one provider. Avoiding them entirely means building more yourself.

Regulation drives hybrid

Banks, hospitals and government bodies often must keep some data on-premises or in-country.

Data gravity

Large datasets are slow and costly to move. Compute usually ends up where the data lives.

Common layers help

Kubernetes, Terraform and OpenTelemetry work across clouds, giving teams one set of tools.

Save yourself the pain

Common mistakes

Oops

Running every app on two clouds 'for redundancy' from day one.

Do this instead

Start with one provider and multiple zones. Add a second cloud only when a clear risk or requirement justifies it.

Oops

Assuming Kubernetes makes moving between clouds effortless.

Do this instead

Storage, load balancers, IAM and databases still differ. Portability needs planning, not just a cluster.

Your mission

A hospital keeps patient records in its own data centre but runs its website on a public cloud. What is this?
