Private and Public cloud storage

What is Private cloud storage?

Private cloud storage is a cloud system built exclusively for one specific company.

No outsiders share the space or equipment.

What are the characteristics of Private cloud storage?

-Single-Tenancy

-High Security and Privacy

-Customisation

-Control

What is Single-Tenancy on Private cloud storage?

Unlike public clouds (multi-tenancy) where your data might sit next to Netflix's or a stranger's data on the same hard drive, private cloud hardware is used only by you.

Why is High Security and Privacy important on Private cloud storage?

Because the infrastructure is isolated, it is easier to meet strict compliance regulations (like HIPAA for healthcare or GDPR for finance).

Why is Customisation important?

The organization can configure the hardware, network, and storage performance exactly how they need it, without being limited by the standard menu options of a public cloud.

Why is Control important?

The organisation has total control over data sovereignty (knowing exactly where the data physically resides).

What are the advantages of Private cloud storage?

- Security is higher than when hardware is shared among multiple customers.

- The cloud setup can be customized to the business's requirements and can offer better performance and reliability as resources aren't shared with other businesses.

- Increased reliability.

What are the disadvantages of Private cloud storage?

- Higher cost as the hardware is dedicated to the single business.

- Scalability is not as easy as a private cloud and would require additional hardware to be installed.

What is Public cloud storage?

A shared infrastructure model where a service provider manages the storage infrastructure (servers, hard drives, and networking) and offers it to multiple unrelated customers over the internet.

What are the characteristics of Public cloud storage?

-Shared Resources (Multi-tenancy)

-Instant Growth (Scalability)

-Pay-as-you-go

-Access Anywhere

What is Multi-tenancy?

In the cloud, thousands of users share the same powerful servers, which makes the service much cheaper for everyone.

What is Instant Growth (Scalability)?

You never run out of space. If you suddenly need to store millions of files, the system handles it immediately. You don't have to go to a store, buy a new hard drive, and install it the extra space is already there.

What is Pay-as-you-go?

A billing model where you pay a monthly bill instead of buying expensive equipment upfront.

How does Pay-as-you-go billing work?

You only pay for what you actually use, similar to an electricity bill.

What happens to your Pay-as-you-go bill if you use less space?

Your bill goes down if you delete files and use less space.

What does Access Anywhere mean?

You can open, edit, and share your data from any phone, tablet, or laptop in the world, as long as you have an internet connection.

What are the advantages of Public cloud storage?

- Cost-effective as the business can easily set the amount of storage needed and increase it on demand.

- Maintenance of the required hardware and software is the responsibility of the third-party supplier.

- Smaller businesses can find public cloud storage beneficial from a technical standpoint.

What are the disadvantages of Public cloud storage?

- There are potential security concerns as the business data is stored on shared infrastructure.

- There are unlikely to be any customization options as the service is provided with the same features to all customers.
