Infrastructure as a Service (IaaS) is a standardised offering, where compute resources, storage and
networking capabilities are supplied by IIG and offered on-demand to replace on-premises servers, for test and development or production use. Organisations are able to self-provision this infrastructure, using a portal to build flexible and scalable IT solutions.
Infrastructure as a Service (IaaS) is a cloud model which allows organizations to outsource computing equipment and resources such as servers, storage, networking as well as services, such as load balancing and content delivery networks. IIG owns and maintains the equipment while the organization rents out the specific services it needs, usually on a “pay as you go” basis.
Servers and storage are fundamental IaaS services. Servers vary in size and cost. Finding the IaaS provider with the right mix of server sizes for your needs can help control costs. Do you need the equivalent of an 8-core, large memory machine to run a relational database along with several low end servers for development and test? Do you need to create a cluster to run Big Data analytics? You may also want to consider the image library provided by cloud providers. You could, of course, start with basic operating systems and configure your own images, but more image options can translate into less image building and patching for your administrators. IIG provides all of the above
Storage is another distinguishing service. You will find basic block storage and local file systems common to IaaS providers. High performance options such as guaranteed IOPs for database applications or terabytes of local solid state disk storage can be a distinguishing factor among providers.
