What is Iaas

IaaS (Infrastructure as a Service): 

A form of cloud computing where a third-party provider hosts virtualized computing resources online. Infrastructure as a Service is also often referred to as Hardware as a Service (HaaS).

With organizations increasingly looking towards IaaS services to help in their organizational endeavors, it comes as no surprise that IaaS providers are coming out from all fronts to woo organizations. While the customer’s primary concerns relate to reliability and security, IaaS providers have a number of other challenges to deal with. IaaS providers help organizations outsource their server, storage and networking needs. All infrastructure and equipment necessary are owned by IaaS providers and help companies balance load and delivery requirements.

Cloud providers offer much more than just simply storing organizations information. A number of them offer monitoring tools and management functions to better aid organizational needs.

As an organization you need to look at the provider’s customer support, the integration of their cloud services with your existing infrastructure and their pricing as it pertains to the amount of resources your company will need.
