What is IaaS?
IaaS, or Infrastructure-as-a-Service, provides on-demand access to IT infrastructure such as storage, network and compute resources required to run workloads. IaaS offerings allow enterprises to access a portion of a consolidated pool of resources to create and use compute infrastructure when needed. IaaS is one of several types of cloud computing models – including Software-as-a-Service (SaaS) and Platform-as-a-Service (PaaS) – that provide access to the Cloud-as-a-Service.
What are the advantages of IaaS technology?
IaaS services provide:
- Improved efficiency, with resources virtualized and pooled to ensure maximum utilization of physical infrastructure
- Increased agility, making it possible for resources to be provisioned on demand and released when no longer needed
- Greater scalability, as IT teams can instantly allocate additional resources to meet peak demand
- Reduced costs, with IaaS offerings available on a pay-as-you-go pricing structure
- Enhanced productivity, with IaaS provisioning available through self-service portals
What is Data Center-as-a-Service?
Data Center-as-a-Service is a form of IaaS offerings, delivering access to a provider’s servers, networking, storage and compute resources. Data Center-as-a-Service may be offered remotely via wide area network (WAN) connections or it may be installed on premises within an organization’s private cloud.
What is Platform-as-a-Service?
Platform-as-a-service (PaaS) is a cloud-based environment where developers can develop, test, run and manage applications. A PaaS offering provides a development environment without requiring businesses to buy, build or manage the underlying infrastructure.
What are the differences between IaaS vs PaaS?
IaaS provides access to general infrastructure resources, while PaaS offers access to resources for developing software.
