Infrastructure as a Service (IaaS)

IaaS, as the name suggests, is a way of providing Cloud computing infrastructure such as virtual machines, storage drives, servers, operating systems & networks, which is also an on-demand service like that of SaaS. Rather than purchasing servers or developing software, clients buy those resources as a fully outsourced service based on their requirement. "Public cloud" is considered as an infrastructure that consists of shared resources, based on a self-service over the Internet. In one word, it is the only layer of the cloud where the customer gets the platform for their organization to outsource IT infrastructure on a pay-per-use basis.

IaaS provides users with:

  • Load balancers
  • Disk storage via virtual machines
  • Software Packages
  • IP address
  • VLANs 

Advantages of IaaS are:

  • Dynamic: Users can dynamically opt & configure devices such as CPU, storage drive, etc.
  • Easy Access: Users can easily access the vast cloud computing power.
  • Renting: Flexible and efficient while renting IT infrastructures.
  • Full control of computer resources along with portability.

Disadvantages of IaaS are as follows:

  • Internet connection is a must.
  • IaaS depends on virtualization services.
  • This service restricts the user-privacy & customization.
