Why is IaaS Attractive?​

Consider the following advantages:

1. Reduced IT costs：Reduces the need for in-house IT staff.
2. Lower operational expenses：Avoids the high costs of building your own data center, including rent, cooling, electricity, etc.
3. Scalable resources：Allows businesses to adjust resources quickly during peak or off-peak periods, preventing unnecessary fixed costs.

Building your own data center can be expensive for most businesses, whereas IaaS provides a more cost-effective alternative.

Features​

1. Highly flexible：Users can rent virtual machines, storage, and network resources as needed.
2. Strong control：Users manage their own OS, applications, and data configurations.
3. Cost-effective：No need to purchase hardware; billed based on usage.

Suitable for​

• Startups：Limited budgets but need to quickly build IT infrastructure.
• Variable resource needs：For businesses with fluctuating demand or short-term projects requiring flexible resources.
• Self-managed environments：Organizations with IT teams who need high control over their systems, applications, and data.

Examples​

• AWS EC2
• Digital Ocean
• Linode
