SaaS, PaaS and IaaS! What They Mean, and Why You Should Care?

I love talking about business which is billions. that’s how the cloud impressed me. May be you have heard of it already what the cloud means. but this will explain the basics of different cloud services..

knowledge pays a big! So know whats this 🙂

What is SaaS?
Software as a service (SaaS) is aptly referred to as software “on demand.” SaaS solutions offer subscription-based access to enterprise applications that service a vast range of functions and departmental needs and are hosted securely in cloud data centers. Many, if not all, of the enterprise products offered by Google and Salesforce offer prime examples of SaaS solutions.
Organizations that operate on SaaS solutions such as Google Apps and salesforce.com are no longer burdened with the time-consuming and costly task of managing software updates, security patches and a host of other administrative duties for on-premise software solutions. SaaS ensures that these tasks are managed quickly, efficiently and affordably on the back-end so that IT teams have more time to work on projects that propel the business forward.
What is PaaS?
Platform as a service (PaaS) is defined in its name; it is the platform that hosts applications provided in software as a service. For example, Google App Engine is a PaaS that hosts Google Apps and a multitude of other softwares-as-a-service. PaaS provides all the infrastructure needed to run applications over the Internet, and is delivered in the same way as a utility like electricity or water. Users simply “tap in” and take what they need without worrying about the complexity behind the scenes. And like a utility, PaaS is based on a metering or subscription model so users only pay for what they use. Examples of PaaS are Google App EngineForce.com and Heroku.
What is IaaS?
Infrastructure as a service (IaaS) enables businesses to move information from on-site servers into the Cloud.  It provides a remote virtual hosting server for file storage, as it enables a user to save all of their file types in a virtual host and retrieve them from anywhere with an internet connection. Examples of IaaS are Google Compute EngineGoogle Cloud Storage and Google Big Query.

Unreleased New Look for Gmail

A video from Google’s YouTube channel (update: the video is now private, but there’s a mirror here) introduces a new Gmail interface. It’s based on the Preview theme that’s already available in Gmail, but there are many other changes: an action bar that uses icons instead of text labels, a completely new interface for conversations, profile pictures next to contacts, a flexible layout that adapts to any window size, display density options like in Google Docs, resizable chat/labels sections, new high-definition themes and an updated search box that includes advanced options.




I don’t see the new interface yet, but it will probably be available soon. It’s interesting that there’s an arrow next to “Mail” and the links to Google Contacts and Google Tasks are missing. Maybe you’ll be able to use the arrow to switch to other Google services.
