CLOUD

FOCUS

Cloud services allow data processing and storage on a networked computer. Data is stored on multiple virtual servers, generally hosted by a third-party structure and not on local computers. This is all based on the On-Demand Formula. The company pays only for what it consumes in terms of bandwidth, resources, time of use, number of transactions, etc. and one does not have to worry about the infrastructure.
By outsourcing some of the production phases, cloud computing enables cost savings and speeds up delivery of services. The management and maintenance of facilities, both hardware and software, are a commitment that the Cloud service provider carries out directly.
Some of the main benefits:

  • Simplicity of solution
  • Implementation speed
  • Flexibility: Cloud solutions are highly adaptable and extensible
  • Open system: easily integrated with external solutions, portability of data, and use from different devices
  • Constant Upgrades: No upgrade costs, no obsolescence in the structure, less management costs.

You can distinguish between three models:

  • SaaS (Software as a Service) is the highest level of service. The business/user doesn’t have to worry about the infrastructure that supports the software specifically at a network level, type of servers, amount of storage, and operating systems. This is all fully funded by the provider. The most common example of SaaS services is that of webmail or Google Apps. In this case, invoicing is related to the number of active users.
  • PaaS (Platform as a Service) is almost identical to SaaS as an operation, but service delivery is related to a software platform which are represented by a number of programs, libraries and services developed by the provider. This allows the business/user to develop cloud applications.
  • IaaS (Infrastructure as a Service) is the virtualization of hardware resources (CPU, RAM, space, and network cards) that allow the flexibility of a physical infrastructure without costs and hardware management costs.
