Understanding Cloud Hosting Service Terminology
SaaS or Cloud Software as a Service
SaaS provides companies with the ability to use a data center to run their applications on the data center’s cloud infrastructure. The user can access their applications from a thin client interface like a web browser. The user does not have any responsibility for the managing the network, operating systems, storage component of the core cloud infrastructure. Client uses the data centers applications running on the cloud infrastructure with the exception of some user specific application configuration settings.
IaaS or Cloud Infrastructure as a Service
IaaS allows the client to determine the processing, storage requirements and network utilization and some other basic computing resources. Like SaaS, the client does not manage the core cloud infrastructure; however, controls the operating systems, storage, deploys their own applications and software. This comes with limited control of limited components like host firewalls.
PaaS or Cloud Platform as a Service
This service offers clients the ability to operate their own applications utilizing program languages supported by the data center. The client can manage these applications deployed on the hosting environment. Like IaaS, the client does not manage or control the core cloud infrastructure like servers, operating systems or storage.
