\"Cloud-Computing\"<\/figure>\r\n<\/div>\r\n\r\n\r\n

These days you will find many IT technology press releases that suggest cloud solutions. Many solutions are indeed on this concept, including mobility, social networks, management of personal data, etc.\u2026 But still, its many terms are unclear. The purpose of this article is to demystify the concept of cloud computing by explaining some of these implementations: Iaas, PaaS, and SaaS.<\/p>\r\n\r\n\r\n\r\n

IaaS, PaaS, and SaaS<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

Cloud computing offers a model for on-demand access to share computing resources, configurable networks, servers, storage, applications, and services that can be rapidly provisioned. The idea is to provide a flawless data processing capacity.<\/p>\r\n\r\n\r\n\r\n

Cloud Computing comes in three distinct models:<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

IAAS (Infrastructure as a Service): This package offers a scalable computing capacity. Its interface level is about the operating system (OS). It is then possible to use its way by installing server software, database, and applications.<\/p>\r\n\r\n\r\n\r\n

PAAS (Platform as a Service): This model offers a higher degree of superiority than provides IAAS: it provides the hardware platform, Operating System (OS) software, and all associated servers: application servers, databases, etc. It is therefore a complete software platform on which it is possible to develop your applications or migrate.<\/p>\r\n\r\n\r\n\r\n

These systems are based on standard environments and multi-technologies (J2EE, NET, and PHP). These systems provide an environment of more complete exploitation by providing solutions for load balancing, monitoring, and management.<\/p>\r\n\r\n\r\n\r\n

SAAS: Software as a Service: This model allows the rental services offered by applications made by the supplier of the solution, which can be consumed by users. This offer not only offers hardware and software platforms on which we can deploy our applications but also provides ready-to-use applications, hosted by the operator of the solution. It is therefore simply use online software where everything is completely transparent to the user.<\/p>\r\n\r\n\r\n\r\n

The principle of all offers of cloud computing is to build on:<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

\u2022 The principles of pooling resources
\u2022 The scalability of resources
\u2022 Adaptation of the capacity on demand
\u2022 Billing \u2013 Pay For What You Use<\/p>\r\n\r\n\r\n\r\n

NEED FOR SPECIFIC INFRASTRUCTURE<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

Cloud computing can meet the specific needs of new infrastructure (disk, bandwidth, computing power) which is based on the pooling of resources that can adapt to its leased capacity need:<\/p>\r\n\r\n\r\n\r\n

\u2022 Better management during the peak loads
\u2022 Responsiveness of the provider to manage these changes immediately.<\/p>\r\n\r\n\r\n\r\n

Applications that have specific and timely manner needs are particular candidates for cloud computing offers. E.g. payroll applications are mostly used only at the end of the month. The rest of the time the application is used very little.<\/p>\r\n\r\n\r\n\r\n

Applications with high loads with regular chances of peak loads: e-Commerce applications during the Festival seasons, SMS servers, Weather forecasts, or any other frequently used applications that have had peak loads for the period of extraordinary events (e.g. Weather alerts on weather forecast websites, News websites during major events, etc.\u2026). The strong variations of loads can extend over several minutes, several hours, or even several days, cloud computing can meet these needs.<\/p>\r\n\r\n\r\n\r\n

Applications generally not used, but with strong peak loads periods can be identified: e.g. tax reporting applications, infrastructure management applications, election vote counting applications, etc.<\/p>\r\n\r\n\r\n\r\n

Managing these applications with traditional hosting infrastructure is very difficult. Two major risks with traditional solutions.<\/p>\r\n\r\n\r\n\r\n
