Apoyo a la Toma de Decisiones en la Compra de IaaS

La dificultad para decidir la compra de un IaaS (Infrastructure as a Service) depende de la complejidad de las opciones de compra dadas por su proveedor y de la complejidad del plan del cliente que quiere realizarla. Es habitual que estos tipos de servicios ofrezcan muchas configuraciones de uso diferentes, y para cada una de ellas sea posible disponer de varias opciones de compra. De este modo, decidir la mejor compra se convierte en una tarea que consume mucho tiempo, tediosa y propensa a errores. En este trabajo inicial, caracterizamos el problema con un caso de estudio ilustrativo y presentamos los desafíos inmediatos para mejorar las herramientas de soporte actualmente disponibles.

Towards the user-centric analysis of the availability in IaaS

Availability is a key property in computational services and, therefore, is guaranteed by Service Level Agreements (SLAs) from the majority infrastructure services, such as virtualization (Amazon EC2, Windows Azure, Google Cloud, Joyent, Rackspace, …) and storage (Amazon S3, Google Cloud Storage, …). These SLAs describe availability in natural language and there are important differences in the scope and penalties that each service provides. Furthermore, descriptions use specific domain terms so they are difficult to understand by service customers. These circumstances make that availability analysis is a tedious, error-prone and time-consuming task. In this paper, we describe in detail this problem and provide a first approach to deal with these SLAs supported on current SLA analysis techniques.

CloudWave: Agile Service Engineering for the Future Internet

After achieving initial market penetration, Cloud Computing stakeholders now call for a next generation of Infrastructure and Software as a Service offering (IaaS and SaaS). CloudWave, an EU-funded FP7 research project, looks to dynamically adapt cloud services to their environment, resulting in improved service quality and optimized resource use. This is supported with an enhanced cloud monitoring that provides holistic analytics of IaaS and SaaS layer services running on the cloud, leading to CloudWave’s innovative, automated adaptation of the infrastructure and application, as well as enabling DevOps-like data and interfaces for the developer. DevOps-like data and interfaces for the developer.
