Optimización de cloud computing por multi-tenant para empresas proveedoras de telecomunicaciones.

Abstract

This thesis carries out a study on how Cloud Computing has generated a great reduction for companies that delegate the provision of various computing resources, such as servers, platforms, networks, software applications and services. This model that provides services and applications is known as Software as a Service (SaaS), which together with their peers, Infrastructure as a Service (IaaS) and Platform as a Service (PaaS), form the world of opportunities offered by computing in Cloud. This paper also analyzes that as the cloud service model has grown, new types of architectures have been created to bring the business to a scale economy, making cloud computing service providers offer the same instance software to several clients, so that they share databases, operating systems and hardware in some cases. Special emphasis is placed on the multi-tenant architecture, in which the benefit offered to both providers and customers is analyzed by the great saving of resources sought with the cloud service, together with the shortcomings present in the architecture, which are related to security in the sharing of resources, service availability and scalability. The last chapter seeks to correct these problems, so as to offer a correct operation and high reliability of the service for customers of cloud computing.
