Cloud computing is quickly becoming the standard way for technology companies to access IT infrastructure, software and hardware resources. The technology enables companies to be able to use applications and other resources managed by third party companies that are stored in high-end server computers and networks. Cloud computing systems are mainly set up for business or research purposes. In this article, we explore the different types of cloud computing solutions.
Cloud computing helps businesses to be more efficient and save on software and hardware that are important for different operations. The definition of cloud computing varies depending on your source but what is generally agreed is that it involves access of software or hardware that are in the “cloud” i.e. use of software or hardware remotely. If your company is using specialized applications where you did not have to set up server or buy hardware or software to run them, then you are probably using a cloud application.
Companies can use cloud computing to increase their IT functionality or capacity without having to add software, personnel, invest in additional training or set up new infrastructure. Below are the major types of cloud computing:
1. Infrastructure as a Service (IaaS)
IaaS is the lowest level of cloud solution and refers to cloud-based computing infrastructure as a fully-outsourced service. An IaaS provider will deliver pre-installed and configured hardware or software through a virtualized interface. What the customers accessing the cloud services do with the service is up to them. Examples of IaaS offerings are managed hosting and development environments.
Your web hosting company is an IaaS provider. Some of the major players offering infrastructure as a service solution include Google, IBM, Rackspace Cloud Servers, Amazon EC2 and Verizon.
Benefits of IaaS Solutions
Reduces total cost of ownership and capital expenditures
Users pay for the service that they want, on the go
Access to enterprise-grade IT resources and infrastructure
