IaaS Characteristics

Scalability:

IaaS services can quickly scale up or down based on demand. IaaS services can easily scale vertically (increasing the power of a single resource) or horizontally (adding more resources). This elasticity allows users to easily adapt to changing workload requirements and avoid over-provisioning.

Measured Service (Pay-As-You-Go):

IaaS computing resources are monitored and metered, providing a pay-as-you-go model. Users are billed for the resources they consume, which can lead to cost savings.

Security:

IaaS providers invest heavily in security measures to protect their users’ data and ensure the privacy of sensitive information.

On-Demand Self-Service:

IaaS allows users to provision and manage resources as needed, without requiring any interaction with the service provider. Users can scale resources up or down based on their requirements.

Resource Pooling:

Resource pooling is one of the key characteristics of IaaS. IaaS service providers employ resource pooling to divide resources across many clients. This allows support for multiple tenants.

Virtualization:

Virtualization is a fundamental component of IaaS. It involves creating virtual instances of computing resources, such as virtual machines (VMs), storage, and networks. Virtualization abstracts the physical hardware, allowing multiple virtual machines to run on a single physical machine.

High Availability and Redundancy:

IaaS platforms often offer features for ensuring high availability and redundancy. This includes the ability to distribute workloads across multiple data centers or regions, automated failover mechanisms, and load balancing.
