IaaS (Infrastructure as a Service) |
This happens when the developer requires an infrastructure where he can do the settings for running an application. IaaS provides full control for the user to hire IT infrastructure services (storage, RAM, processor, etc.) virtually no operating system, which is of course the selection of the operating system chosen by the user desires.
If the SaaS and PaaS less very beneficial for the company, IaaS is very beneficial for smaller companies that require an IT infrastructure without having to buy the necessary tools.
So of these differences can be summarized as follows, if we need an application, then we use SaaS. When we have an application and we want to install and run it on the Internet, we use IaaS. Whereas if we do not have an application at all, but we want to run on the Internet, we can build it through PaaS. Yep, it's probably my explanation about SaaS, PaaS and IaaS, may be useful.
Cloud Computing service fall into three categories :. Infrastructure, platform or software / applications Cloud providers is identified based on the services they provide. A service provider may offer one or more or a combination of all of the above. Here is the first category of cloud computing services.
Infrastructure as a Service (IaaS): An IaaS provider offers basic computing resources. For this reason, they also call cloud resources. They provide the resources are managed and measured as a service to users. They basically provide enhanced virtualization capabilities. The resources provided include
Data and Cloud Storage concerned with reliable access to the data size of the potentially dynamic with the requirements of access and quality parameters. Examples of companies that provide this is :
Amazon S3
The Amazon Simple Storage Service (The Amazon S3), providing developers and IT teams with a safe, durable, highly-scalable object storage. The Amazon S3 is easy to use, with a simple web services interface to store and retrieve any amount of data from anywhere on the web. With The Amazon S3, you only pay to the storage you actually use. There is no minimum fee and no setup fee.The Amazon S3 can be used alone or together with other AWS services such as The Amazon Elastic Compute Cloud (The Amazon EC2), The Amazon Elastic Block Store (The Amazon EBS), and The Amazon Glacier, as well as third-party storage repository and gateway.
The Amazon S3 provides a cost-effective object storage to various use cases including cloud applications, content distribution, backup and archiving, disaster recovery, and analysis of large data.

Azure SQL Database
Microsoft SQL Azure Database is the relational database-as-a-service that provides predictable performance, scalability, of business continuity, data protection, and is close to zero administration cloud developers and solution architects.quoted from:http://msdn.microsoft.com/library/azure/ee336279.aspx
IaaS (Infrastructure as a Service) Compute Cloud
Compute clouds provide access to computing resources are CPU or processing power. The cloud-enabled application that is run by the user can access the resource. Company examples that provideAmazon EC2
The Amazon Elastic Compute Cloud (The Amazon EC2) a web service providing resizable compute capacity in the cloud. Designed to make web-scale computing easier for the cloud for developers.Amazon EC2 a web service that allows a user to get and configure capacity with minimal friction. It gives the user full control of the user computing resources and lets users run on The Amazon proven computing environment.
The Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing the user to quickly scale capacity, both up and down, as computing needs of the user.
The Amazon EC2 changes the economics of computing allows users to pay only for capacity that is really user use. The Amazon EC2 provides developers the tools to build failure resilient applications and isolate yourself from general failure scenarios.

Zimory ( Global Cloud Services )
Between the future challenge of IT industry and globalization of markets and the 4.0 value chain. The World Cloud Computing Services include a dedicated, on demand IT a Sourcing - adapted to local needs and specific data.
