IAAS AND PAAS
Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) are commonly offered together by most carriers. IaaS enables you to pay granularly for computing capacity, RAM, data storage, and network bandwidth based upon usage. Basically, IaaS is the physical part of the Cloud. PaaS refers to the platform or Operating System, such as Windows, Linux, etc.
Outsourcing these services to a Cloud provider has many benefits, including:
- Hardware Outsourcing: You no longer need to worry about upgrading your gear or End of Life support on your hardware. IaaS also eliminates large upfront CAPEX expenditures.
- Operating System Management: With PaaS, there is no need to buy licenses or install new patches/updates.
- 24/7 Support and Availability: IaaS and PaaS come fully managed by Cloud service engineers and carrier-grade Service Level Agreements.
