What is IaaS?
Infrastructure as a Service or IaaS is an instant computing infrastructure which is managed and provisioned over the Internet. It is one of the three layers in cloud computing along with PaaS and SaaS. Iaas is valued by organizations for its capabilities to providing a solution which helps companies avoid the complexity and expense of buying and managing their own physical servers. There are many different services that come under Infrastructure as a Service, but you only need to pay for the ones you need and use, without having to pay for all of them.
Here are the common things that businesses use IaaS for:
Test and Development: Tests and development environments can be quickly dismantled and set up using IaaS. Teams can also quickly set up and scale up the development testing environment up and down.
Backup, Storage and Recovery: There is no need for organizations to invest in infrastructure for the storage of information businesses using Infrastructure as a Service are able to store information and also find options for backup and recovery of this data. Planning and management is also simplified, thanks to IaaS.
Website Hosting: Compared to traditional website hosting, the websites hosted through IaaS will cost you much less.
Web Apps: You will find all the infrastructure that is needed to support web apps, including storage, application and web servers, as well as networking resources. In addition, you can quickly deploy your web apps and can scale the infrastructure up or down as and when needed.
How It Works
The Cloud: Just as all other cloud computing services, IaaS provides you an access to all the computing resources in a virtual environment where clients can build their own IT platforms as they are given an access to various virtualization components.
Virtualization Hardware: The computing resource you are provided with is specifically based on the virtualized hardware. In simple words, it is custom computing infrastructure that you get with IaaS. Although, there are other offerings as well which include, but are not limited to; virtual server space, bandwidth, network connection, load balancers and IP addresses.
Cloud Servers: The pool of hardware resources are pulled through a number of servers which distribute media over numerous data centres. However. maintaining all of these is the duty of the cloud provider. Thus, you won’t have to worry about anything at all.
Benefits of IaaS
Scalability: No delays in expansion of capacity nor any wastage of capability
Cost Effective: You are only going to be paying for the services you use. Thus, it will cost you much less than all the other options you have.
Independence of Location: You can access the service from anywhere and anytime with an active Internet connection. The security protocol of the cloud needs to allow the connection.
Safe Data: You don’t have to worry about losing your important data just because the data centre collapsed, or any physical mishap happened. All the data will be stored in the cloud and will be safe whenever you need to use it.
