1. Introduction to Infrastructure as a Service (IaaS)
What is IaaS?
Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. Unlike traditional on-premises infrastructure, IaaS delivers computing power, storage, and networking capabilities on a pay-as-you-go basis. This model allows businesses to scale their IT infrastructure dynamically and efficiently, reducing the need for significant upfront capital investments.
Primary Features of IaaS
- Scalability: Easily scale up or down based on demand.
- Cost-Efficiency: Pay only for what you use, reducing capital expenditure.
- Flexibility: Access to a broad range of computing resources and services.
- Automation: Automated deployment and management of resources.
- Security: Enhanced security features to protect data and applications.
2. Key Benefits of IaaS
