Metodología basada en un enfoque SOA de un plan de recuperación de desastres para una plataforma de interoperabilidad

Abstract

El trabajo de investigación consiste en desarrollar una Metodología basada en un enfoque SOA (arquitectura orientada a servicios) para la implementación del Plan de Recuperación de Desastres aplicada a una Plataforma de interoperabilidad en cuya configuración se encuentran dos Data Centers o Centros de Datos uno como principal y el otro de contingencia con software SOA y componentes de alta disponibilidad. Para este estudio se va a tomar como muestra un grupo empresarial donde se está aplicando esta tecnología de información, para poder desarrollar una metodología, basada en el enfoque SOA, para el Plan de Recuperación de Desastres (PRO) o Disaster Recovery Planning (DRP), la que va estar compuesta de una serie de procedimientos que van a generar productos parciales que al final servirán de fundamento para el Plan propiamente dicho. Adicionalmente, se tiene el propósito de demostrar esta investigación, manipulando la variable independiente: Metodología basada en un enfoque SOA, del Plan de Recuperación de Desastres (PRO) y verificando su incidencia en la variable dependiente: Servicio de la Plataforma de lnteroperabilidad, además mediante la formulación de indicadores e índices, dichas variables podrán ser medidas y demostrarse en el análisis de los resultados, el valor agregado que brinda esta metodología en el desarrollo del PRO para esta plataforma de interoperabilidad.

The disaster recovery plans have increased their dominance, after 11 September 2001, in which thousands of international organizations based in the Twin Towers were forced to put in test plans, most of which failed with different impacts ranging from their disappearance to the affectation in their operation, with recovery periods that took months and years, in some cases, to reach the same level of operation they had before the disaster. Large business groups in the first decade of the XXI century have been looking greater flexibility in their IT services through the called “Service Oriented Architecture“ (SOA), which has given them, in general: • Greater interoperability between existing applications, external and future applications • Agility in business processes that enable faster time implementation of required changes in the business processes of the company. • Lower maintenance costs to ensure the business capabilities (software components) are consolidated in a small amount of shared services. Service-oriented architectures (SOAs), based on Web service standards, have emerged as the leading industry wide enabler for interoperability with mechanisms to exchange processes and I or data between heterogeneous systems. In the web environment, interoperability is a necessary condition to have full access to the information available. Companies that are embracing SOAs are finding huge benefits, but could be lost if we don 't have an effective Disaster Recovery Plan, based on SOA's approach.

This research is for business groups using SOA, that have an interoperability Platform with high availability hardware and software in two data centers, (principal and contingency one) but that need a framework in order to use far developing a Disaster Recovery Plan. The methodology, as a result of this investigation has 4 proposal steps for developing the plan and includes the maintenance of this plan for any changes in the Platform. With this DRP based on SOA's approach, Business groups, after a disaster, can have their contingency's data center operative in minutes, as well as, once recovered its main data center, return its operations in less than an hour.
