Framework para a construção de “portais de negócio” para gestão de solicitações de consumidores IaaS na HP Cloud
MSc Post-Graduation

The HP CloudSystem Matrix (CSM) is a part of the HP software stack for cloud computing that covers all relevant service levels: IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service). Although it rests at the base of the stack, i.e., only offers the IaaS level, it is an extremely complex product since it interacts with all infrastructures: computing (i.e., physical and virtualized servers), storage (from individual drives to disk arrays), and networking (Ethernet and FC networks) Despite all the (real) infrastructure´s complexity that CSM deals with, the delivery (to end users – a.k.a. infrastructure consumers) of infrastructures for application support, becomes a conceptually simple task: (1) the administrator defines which infrastructure resources are available to integrate the cloud offer; (2) the architect defines templates for those architectures he deems appropriate for the end users (e.g., 3-tier architecture for an ERP - Enterprise Resource Planning - solution); (3) the end user chooses the template that better suits its needs, and then submits a request for the delivery of the infrastructure. The interaction between the different counterparts (1), (2) and (3) and the CSM is fundamentally realised over portals; however, especially in the case of the end user, the portal has been considered "complex", since it presents too much technical information, "rigid", since it is not customizable (e.g., to suppress the "too much technical information"), and "coarse", since it does not allow a finer-graned specification of the infrastructure´s attributes that are required (e.g., it allows to change the number of CPUs and the amount of memory in the server, but it does not allow one to choose the disk technologies, e.g. SSD instead of FC, or 15K instead 10K rpm). Therefore, the final goal of this dissertation is to develop a framework that allows, with a set of pre-defined settings and customizable layouts, to define portals that are integrated with HP CloudSystem Matrix and enables a simpler user interaction. In this work we studied: service and cloud implementation models; virtualization (not only server virtualization, but also storage and network virtualization), the foundation of all cloud technologies; modules and APIs that interoperate with CSM, namely API-MOE and API-VMware. Finally, we present a framework (prototype) implemented in a multi-layer architecture (N-tier) with standard technologies: TCP/IP for the communication stack, REST (Representational State Transfer) to control the interaction and the client/server information flows and XML (eXtensible Markup Language) and JSON (JavaScript Object Notation) for the data formats.
