Today, when we talk about outsourcing, we quickly come to talk about Cloud Computing. But what lies behind this nebulous term appeared in the 2000s, and what are the future developments on cloud services? These questions are legitimate, since 2008-2009, this term has been widely marketed and so-called “cloud” offerings are now widespread. With the school parent app you can have the smart details.
Let’s agree on a definition of Cloud Computing
The Cloud is commonly defined as the provision of computer energy through the Internet.The National Institute of Standards and Technology (NIST) today provides a more precise definition. Indeed, this institute has tried to define for a few years what exactly Cloud Computing, and finally settled on an official definition in 2011. According to him, the Cloud Computing must have 5 essential characteristics:
This term, widely used in the marketing campaigns of publishers, hosters or outsourcers, has become a commercial argument. We note, however, that many offers saying “Cloud” do not necessarily fulfill all the criteria mentioned.
- The different deployment models
- Cloud Computing exists in different forms:
Internalized private cloud:
- “cloud” internal to the company (the company being the owner and manager of infrastructures) or Cloud entirely dedicated to the same company, accessible via secure networks, operated by internal teams.
Outsourced Private Cloud: Cloud Computing platform that aims to provide, externally, services and guarantees equivalent to those offered by an internal private cloud, while enjoying the benefits of management services by a third party. It can be accessed over the Internet or through a private network.
Public Cloud: It is external to the company, accessible via the Internet or a private network, managed by an external operator owning the infrastructures, with resources totally shared between all its customers. With the free online registration software you can find the best deals.
Hybrid cloud: it is the conjunction of two or more clouds (public + private) brought to “cooperate”, to share between them applications and data
But what deployment model to choose? First of all, the cloud (whatever the model) meets a need for flexibility. The public cloud is designed for a multiplicity of companies. It therefore offers standardized solutions whereas the private cloud is designed for a single organization and will therefore be rather specific. The use of the childcare software programs comes utmost essential there.
In general, different cloud models can be articulated around 3 levels of services
Software as a Service (SaaS), where the customer accesses services via his internet browser. This offer is generally aimed at the company’s businesses. Typical applications are CRM, BI, messaging and other collaborative tools. We will note that we are seeing more and more emerging SaaS ERP offers. The Platform as a Service (PaaS) is an external solution that offers a software suite and integration and monitoring tools; For example, a web server (Linux + Apache + MySQL + Php).
