aaS – a quick reference guide to "as a service"

You've heard them or read them all - SaaS, HaaS, IaaS, PaaS   Seems like there's a new one everyday and what do they all mean, anyway?

SaaS - Software as a Service -  or software that is available through the internet.  Simply put, instead of purchasing the software and installing it on your own hardware (computer or server) the software is available over the internet.  Also, data is typically stored by the SaaS provider instead of locally on the user's computer or server.

HaaS - Hardware as a Service -  involves providing physical hardware and switches that form the backbone of the cloud to a user. The HaaS provider operates, manages and upgrades the hardware on behalf of its customers for the lifetime of the contract.

IaaS - Infrastructure as a Service - is one type of cloud computing in which a vendor offers various infrastructure components such as hardware, storage, and other fundamental computing resources.

PaaS - Platform as a Service - facilitates the deployment of applications without the cost and complexity of buying and managing the underlying hardware and software, providing all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely available from the Internet — with no software downloads or installation.

You may notice that all of the "as a Service" models have one common theme:  a trusted, experienced provider.  Want to know more?  Call us 203.987.4566 or email sales@virtualdensity.com for more information.  We're here to help!
