This document discusses the different types of cloud computing services: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS refers to companies that provide access to remote server hardware, storage, and networking resources over the internet. PaaS refers to companies that provide development platforms and tools for building applications in the cloud. SaaS refers to software applications that are hosted in the cloud and accessed via a web browser. Examples of companies providing each type of cloud service are given.

November 14, 2011 | Sean Ludwig 5 Comments Share Anyone who who follows technology trends has undoubtedly heard the term cloud service thrown around a few gazillion times over the past few months. But if you dont know the difference between terms such as PaaS, IaaS and SaaS, dont fret youre far from alone. Lets start at the beginning. Cloud is a metaphor for the Internet, and cloud computing is using the Internet to access applications, data or services that are stored or running on remote servers. When you break it down, any company offering an Internet-based approach to computing, storage and development can technically be called a cloud company. However, not all cloud companies are the same. Typically, these companies focus on offering one of three categories of cloud computing services. These different segments are called the layers of the cloud. Not everyone is a CTO or an IT manager, so sometimes following the lingo behind cloud technology can be tough. With our first-annual CloudBeat 2011 conference coming up at the end of this month, we thought this would be a good opportunity to go over the basics of what purpose each layer serves and some company examples to help give each term more meaning. Layers of the cloud A cloud computing company is any company that provides its services over the Internet. These services fall into three different categories, or layers. The layers of cloud computing, which sit on top of one another, are Infrastructure-as-a-Service (IaaS), Platform- as-a-Service (PaaS) and Software-as-a-Service (SaaS). Infrastructure sits at the bottom, Platform in the middle and Software on top. Other soft layers can be added on top of these layers as well, with elements like cost and security extending the size and flexibility of the cloud. Here is a chart showing simplified explanations for the three main layers of cloud computing: venturebeat.com/2011/11/14/cloud-iaas-paas-saas/ 1/8
W :101 d1/3C/21 1uol 2 IaaS: Infrastructure-as-a-Service The first major layer is Infrastructure-as-a-Service, or IaaS. (Sometimes its called Hardware-as-a-Service.) Several years back, if you wanted to run business applications in your office and control your company website, you would buy servers and other pricy hardware in order to control local applications and make your business run smoothly. But now, with IaaS, you can outsource your hardware needs to someone else. IaaS companies provide off-site server, storage, and networking hardware, which you rent and access over the Internet. Freed from maintenance costs and wasted office space, companies can run their applications on this hardware and access it anytime. Some of the biggest names in IaaS include Amazon, Microsoft, VMWare, Rackspace and Red Hat. While these companies have different specialties some, like Amazon and Microsoft, want to offer you more than just IaaS they are connected by a desire to sell you raw computing power and to host your website. PaaS: Platform-as-a-Service The second major layer of the cloud is known as Platform-as-a-Service, or PaaS, which is sometimes called middleware. The underlying idea of this category is that all of your companys development can happen at this layer, saving you time and resources. PaaS companies offer up a wide variety of solutions for developing and deploying applications over the Internet, such as virtualized servers and operating systems. This saves you money on hardware and also makes collaboration easier for a scattered workforce. Web application management, application design, app hosting, storage, security, and app development collaboration tools all fall into this category. Some of the biggest PaaS providers today are Google App Engine, Microsoft Azure, Saleforces Force.com, the Salesforce-owned Heroku, and Engine Yard. A few recent PaaS startups weve written about that look somewhat intriguing include AppFog, Mendix and Standing Cloud. SaaS: Software-as-a-Service moc.taeberutnev 2
101 11/3l2/21 duo C The third and final layer of the cloud is Software-as-a-Service, or SaaS. This layer is the one youre most likely to interact with in your everyday life, and it is almost always accessible through a web browser. Any application hosted on a remote server that can be accessed over the Internet is considered a SaaS. Services that you consume completely from the web like Netflix, MOG, Google Apps, Box.net, Dropbox and Apples new iCloud fall into this category. Regardless if these web services are used for business, pleasure or both, theyre all technically part of the cloud. Some common SaaS applications used for business include Citrixs GoToMeeting, Ciscos WebEx, Salesforces CRM, ADP, Workday and SuccessFactors.
