IaaS is the base of the Cloud Computing paradigm, many people confuse CC with IaaS, thers just use the term Cloud Computing when they are in fact talking about IaaS. IaaS has also been referred to as "Everything as a Service" and "Hardware as a Service".
IaaS offers CPU, memory, storage, networking and security as a package. IaaS is the virtual machine in the sky.
With IaaS, you can choose from a range of predefined virtual machines and load packaged operating system images to it.
Well known and whidely trusted IaaS providers that offer services to the general public are: Amazon, Joyent, GoGrid and FlexiScale and Rackspace Cloud.
Amazon is probably the best known of the providers, Joyent is also huge and hosts some Facebook applications and the the social network LinkedIn, among others.
By moving your infrastructure to "the cloud", you have the ability to scale as if you owned your own hardware and data center (which is not realistic with a traditional hosting provider) but you keep the upfront costs to a minimum.
Benefits of IaaS:
1. Ability to scale on demand, instantly.
2. Per Hour billing, you only pay for what you use.
3. Ideal for startup business, where one of the most difficult things to do is keep capital expenditures under control.

thanks for post, infrastructure as a service is similar to saas in that a product is offered via the Internet to a client as an on-demand service; but instead of software, IaaS delivers hardware such as servers, network equipment, memory, CPUs, and disk space.
ReplyDeleteYou may be wondering how it’s possible to deliver physical hardware over the Internet. Well an easy way to understand IaaS is to think of website hosting. When you pay a company like Network Solutions or GoDaddy.com to host your website, you’re buying physical space on their servers for your web files to reside. Using the Internet you can add, remove, or modify those files just as you would if that server was in your office - except in this instance you’re working with equipment that may be thousands of miles away.
So why would you want to pay a monthly fee for hosted equipment instead of just having it in-house? Here are just a few of the reasons why companies are turning to IaaS:
Scalability:
Just as with SaaS, IaaS is a pay-as-you-go model which allows you to scale up or down depending on your needs. When it comes to pricey hardware, you can save a lot by buying only what you use.
Disaster Recovery:
Fire, theft, malfunctioning sprinklers – there are a myriad of ways to lose equipment and data. With IaaS your hardware and the data located on them are housed in secure data centers which are mirrored, backed up, and typically come with a Service Level Agreement which makes getting your services back up and running in the event of a disaster the vendor’s problem and not yours.
Time Back:
With your infrastructure being hosted offsite you free up your IT staff to focus on value-added tasks such as planning and development, instead of running around patching machines and fixing bugs.
Thanks Mike for sharing such a valuable information.
