Cloud Computing is based on 3 different services:
Infrastructure, Platform and Applications, all found on the Internet Cloud.
Infrastructure:
Infrastructure as a Service (IaaS) , is the basis of all. It is where it all begins and develops.
It is where all informatics resources are provided, such as servers, connections, storing and other necessary tools to serve the different needs of a wide range of organizations, making them easier, speedier and more economically viable.
The main benefit is the capacity it has to quickly provide required resources. You do not need to wait days, weeks or months to obtain new services. On the contrary, you can obtain them in a matter of minutes.
As fast and simple as it takes to acquire servers, it takes to discard and replace them. And we perform this exchange for you and make it transparent.
Platform:
Known in the cloud as Platform as a Service (Paas)), it gives all facilities required to support the complete cycle of building and delivering applications based on the web and on services totally available on the Internet, without the need to download software or special set ups.
PaaS includes developing applications, testing and hosting as well as equipment- supporting, web-integrated services, scalability, storing and assisting developers.
With PaaS, the ISVs and informatics departments may focus on innovating ideas instead of working on complex infrastructures. By levering PaaS, organizations can redirect attention from these complexities to concentrate on efficient budget management, creating applications that provide real solutions, and ultimately achieving successful results in your business.
Applications:
Known in the cloud as Software as a Service (SaaS), it is a software developing model in which an application lodges in a service provider on the internet cloud and is utilized by different users.
By avoiding the process of setting up and running applications for devices of each individual user, SaaS alleviates high costs of software maintenance, support and upgrading.
The difference between SaaS and initial applications available on the web is that SaaS solutions were specifically developed as leverage of web technologies, as the navigator, by being web-designed.
Design and architecture of SaaS applications are specifically created to be implemented simultaneously by different users, generating important scale economies regarding development, management and support throughout the life cycle of software development.
