Cloud Computing has three fundamental service models IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service). IaaS is responsible for providing access to the resources of a cloud computing system with other cloud computing resources from corner to corner on internet or a public connection. It is the computing resource that is provided to a virtualized hardware or a computing infrastructure. IaaS consists of IP addresses, bandwidth, virtual server space, load balancers and network connections. There are many data centers that contain a bundle of servers with group of hardware resources in a cloud but the client can access only the virtualized parts to make their individual Cloud IT podiums.
Enterprise customers can use IaaS to make it easier for their customers to get cost effective and easily scalable IT solutions. The resources can be purchased or installed and integrated by the business owners if they want to expand their resources.
See the following features of IaaS and how it can be used by enterprise.
1 – Virtual local area networks and private clouds with grouped server and networking resources can store the data and operate it for the everyday tasks easily. Extending organizations can balance their structure as per their development while private clouds, that are available to the business itself, can secure the capacity and exchange of the delicate information that a few organizations are required to handle.
2 – Websites are stored on the virtual servers that are grouped by the physical servers. There are many benefits of using a cloud hosting for a website such as vast network of physical servers and the ability to deal with even the unpredicted demands of a websites.
3 – The cloud hosting capabilities can be enhanced by using the virtualized network of interrelated virtual servers that are called Virtual Data Centers or VDCs.
Benefits of IaaS or benefits of Infrastructure as a Service:
1 – Users can use the resource at any time when they need without any delay and the no fear of unused capacity wastage.
2 – The clients have to make no investment in hardware as all this is done by the cloud service provider so it saves the time and money of the clients.
3 – The clients only pay for the resources they use and the service can be accessed at any time on demand.
4 – One of the best features is that the clients can access the service from anywhere if they have an internet connection available.
5 – The security is a big plus with a public cloud or a private cloud as it benefits from the physical security used by the servers which are hosted inside a data centre.
6 – In this service there is no even a single point of failure. If one of the server is affected or fail to function the group of hardware resources are there to use. Even if the whole data center is not working but still the IaaS service could run effectively.
