Types of cloud computing services

1. Software as a Service (SaaS)
SaaS Cloud Computing services is the most popular first. Software as a Service is a further evolution of the concept of ASP (Application Service Provider). As the name implies, SaaS makes it easy for users to take advantage of the resources of software by subscription. So do not need to spend a good investment for in-house development or licensing of purchase.

On a subscription basis via the web, users can directly use the various features provided by the service provider. Only with the concept of SaaS, customers do not have full control over the applications they rent. Only the application features that have been provided by the course providers that can be rented by the customer.

And because the architecture of SaaS applications that are multi-tenant, forcing providers to provide only the features that are general, not specific to the needs of specific users. However, customization is not necessarily prohibited, although only for a limited scale and function.

But with the development of market and technological advances of programming, the limitations it would be reduced in a time not too long. For example SaaS services, of course we have to mention online CRM service Salesforce.com Marc Benioff commanded and has become an icon of this SaaS.

In addition Zoho.com, at a very affordable price, providing SaaS services are quite diverse, ranging from services such as Google Docs word processor, project management, to invoicing online. Online accounting services are also available, as provided by Xero.com and much more. IBM with its Lotuslive.com can serve as an example for SaaS services in the area of ​​collaboration / unified communication.

2. Platform as a Service (PaaS)
As the name suggests, PaaS is a service that provides ready-made modules that can be used to develop an application, which of course can only run on that platform.

As well as service SaaS, PaaS users do not have control over the basic computing resources such as memory, storage, processing power, etc., which are controlled by the service provider.

Pioneers in this area is Google AppEngine, which provides a variety of tools to develop applications on the platform of Google, using the programming language Python and Django.

Then Salesforce also provides services through Force.com PaaS, providing modules for developing applications that use the Salesforce platform above the Apex language.

And maybe that rarely do we know that Facebook can also be considered to provide a PaaS service, which allows us to create applications on top of it. The one that managed to reap huge profits from the service PaaS Facebook is a company called Zynga, which last year alone managed to reap a net profit of more than US $ 100 million, greater than the profit made by Facebook itself.

You might be a little surprised if I tell you that Zynga could be a big profit from applications is not at all serious, but containing addictive substances outstanding namely: Farmville, which until now has managed to make 80 million more people up into a diligent farmers plowing, planting and harvesting and milking cows for their benefit.

3. Infrastructure as a Service (IaaS)
IaaS is one level lower than PaaS. This is a service that â € œmenyewakan "basic information technology resources, which include storage, processing power, memory, operating system, network capacity and others, which can be used by tenants to run its applications.

Its business model is similar to a data center provider that rents space for co-location, but this is more to the micro level. Tenants do not need to know, with what machines and how service providers provide IaaS services. Importantly, the demand for them on the basis of the information technology resources that can be met.

The fundamental difference with today's data center services is IaaS allows customers perform addition / subtraction capacity in a flexible and automated. One of the pioneers in the provision of IaaS is that Amazon.com launched Amazon EC2 (Elastic Computing Cloud).

Services Amazon EC2 provides a wide selection of rental ranging CPU, storage media, equipped with the operating system and application development platform that can be rented at an hourly calculation.
