Cloud Computing is a new model of consumption and delivery inspired by internet services.
The basic characteristic of this model is that computing resources and services, such as infrastructure, platform and applications, are offered and consumed as services over the Internet without users having to have any knowledge of what happens behind.
Delivers greater efficiency, massive scalability and faster and easier software development
It is a model of provisioning IT resources that enhances the provision of IT services and business services, facilitating the operation of the end user and the service provider.
Reduces the cost of technical personnel, installations, software and maintenance tasks.
All this is done reliably and safely.
Characteristics:
- Auto Repairable: In case of failure, the last "backup" of the application automatically becomes the primary copy and a new one is generated.
- Location and device independence.
- Use of Virtualization: applications are independent of hardware Multipurpose: It allows different customers to share the infrastructure in the cloud without worrying about it and without compromising their security and privacy.
- Elasticity: Resource allocation can increase or decrease without affecting performance.
- Scalability: Fair allocation of resources. Meet a very strong demand in the provision of a service, but in a very direct way, immediate in time, with an impact on management and cost that is almost flat
- Governed by a service level agreement (SLA)
Main advantages of cloud computing
1) Self-service. Demand
2) Multi-ubiquity in access
3) Speed of provision
4) Location Independent
5) Real elasticity of resources
6) Flexible pricing and billing model
7) Infrastructure not visible to the end user
8) Standardized services at a lower cost
9) Improve user experience
