I still remember the amazement I felt running VMware 20 years ago. Today, it runs entire private clouds. Here are some myths about the private cloud.

Yesterday I wrote about the evolving cloud landscape and how the public cloud isn't always the best fit. The rich comments caught me by surprise.

Some snippets:

- Cloud can get pricey quickly without good controls.
- The largest cloud instance is sometimes too small.
- Seek cloud fit instead of following hype cycles.

Today, l want to focus on common myths of private cloud deployments - and when it makes sense to use one.

### When to go private cloud

Private clouds have characteristics that make them ideal for multiple scenarios:

- Consistent or steady-state workloads.
- To meet compliance requirements.
- When latency is critical.

Myths abound about private clouds, unfortunately.

Here are 3 of them.

### It's stuck in the past

Private clouds have evolved; it now supports the latest technologies and use cases.

Expect capabilities like:

- Self-service cloud portals.
- Native container capabilities.
- Non-disruptive upgrades, patching.
- Advanced support for AI/ML workloads.
- Integration with automation tools for IaC\*.

*\*Infrastructure as Code*

### Too expensive

Once upon a time, not having to pay up-front for infrastructure enticed many businesses to switch to the public cloud.

These days, we have OpEx financing or even consumption-based pricing for private clouds. Moreover, private clouds also offer unique characteristics to reduce costs.

**(a) Memory tiering**

Advanced memory techniques like NVMe memory tiering can reduce DRAM utilisation by moving less-used memory pages to disk - resulting in higher consolidation ratios.

**(b) Overprovisioning**

Overprovisioning on a private cloud can save money by running more VMs per server and potentially deferring capital expenditures.

### It has limited scalability

The elasticity of public clouds means it is traditionally seen as more scalable. However, modern private clouds support many hundreds of servers - and can even provision extreme VMs with up to 1,000 vCPUs.

And with a modern solution like VMware Cloud Foundation 9, the entire private cloud is managed centrally from a single interface.

From what I've heard, enterprises in Asia have made the move to private cloud.

- A major commercial bank.
- A top 10 stock exchange.
- An online retailer.

Do you know of any other private cloud misconceptions that are no longer true?
