Automation of the Continuous Integration (CI) - Continuous Delivery/Deployment (CD) Software Development

Continuous Integration (CI) is a practice in software development where developers periodically merge code changes in a central shared repository, after which automatic versions and tests are executed. CI entails an automation component (the target of this project) and a cultural one, as developers have to learn to integrate code periodically. The main goal of CI is to reduce the time to feedback over the software integration process, allowing to locate and fix bugs more easily and quickly, thus enhancing it quality while reducing the time to validate and publish new soIn traditional software development, where teams of developers worked on the same project in isolation, often led to problems integrating the resulting code. Due to this isolation, the project was not deliverable until the integration of all its parts, which was tedious and generated errors. The Continuous Integration (CI ) emerged as a practice to solve the problems of traditional methodology, with the aim of improving the quality of the code. This thesis sets out what is it and how Continuous Integration is achieved, the principles that makes it as effective as possible and the processes that follow as a consequence, to thus introduce the context of its objective: the creation of a system that automates the start-up and set-up of an environment to be able to apply the methodology of continuous integration

Planning with Global Constraints for Computing Infrastructure Reconfiguration

This paper presents a prototype system called SFplan- ner which uses an automated planning technique to generate workflows for reconfiguring a computing infras- tructure. The system allows an administrator to specify a configuration task which consists of current state, de- sired state and global constraints. This task is compiled to a grounded finite-domain representation as the input for the standard (unmodified) Fast-Downward planner in order to automatically generate a workflow. The ex- ecution of the workflow will bring the system into the desired state, preserving the global constraints at every stage of the workflow

Automated Software Configuration for Cloud Deployment

Nowadays the Internet is being used as a platform for providing a wide variety of different services. That has created challenges related to scaling IT infrastructure management. Cloud computing is a popular solution for scaling infrastructure, either by building a self-hosted cloud or by using cloud platform provided by external organizations. This way some the challenges related to large scale can be transferred to the cloud administrators. OpenStack is a group of open-source software projects for running cloud platforms. It is currently the most commonly used software for building private clouds. Since initially published by NASA and Rackspace, it has been used by various organizations such as Walmart, China Mobile and Cern nuclear research institute. The largest production deployments of OpenStack clouds consist of thousands of physical server computers located in multiple datacenters. The OpenStack community has created many deployment methods that take advantage of automated software configuration management. The deployment methods are built with state of the art software for automating different administrative tasks. They take different approaches to automating infrastructure management for OpenStack. This thesis compares some of the automated deployment methods for OpenStack and examines the benefits of using automation for configuration management. We present comparisons based on technical documentations as well as reference literature. Additionally, we conducted a questionnaire for OpenStack administrators about the use of automation. Lastly, we tested one of the deployment methods in a virtualized environment

Viability analysis of infrastructure managers for the automated deployment of virtual HPC clusters on Cloud environments

Due to the increase of hybrid environments and the rise of Cloud resources in the IT sector, we have also seen an increase in the complexity of the administration we face today. Today, more than ever, automation tools are needed to facilitate not only the creation but also the management of these new environments. The lack of standardization, especially for HPC systems, forces us to present a proposal to evaluate the different tools that claim to facilitate the automation of this type of systems in Cloud environments and a subsequent analysis of them. In this Master's Thesis we will discover the importance of Cloud environments in HPC systems, the challenges that this presents and an analysis methodology that will serve as a reference for administrators and IT professionals who need to manage such complex and dynamic environments as HPC clusters in Cloud environments.Debido al aumento de entornos híbridos y al auge de los recursos Cloud en el sector IT, se ha podido observar también un incremento en la complejidad de administración de los mismos. Hoy más que nunca son necesarias las herramientas de automatización que faciliten no sólo la creación sino también la gestión de estos nuevos entornos. La falta de estandarización especialmente para los sistemas HPC fuerza a presentar una propuesta de evaluación de las distintas herramientas que presumen de facilitar la automatización de este tipo de sistemas en entornos Cloud y un posterior análisis sobre las mismas. En este Trabajo Final de Master descubriremos la importancia de los entornos Cloud en los sistemas HPC, los retos que ello presenta y una metodología de análisis que sirva de referencia para administradores y profesionales del sector TI que se vean en la necesidad de gestionar entornos tan complejos y dinámicos como los clústeres HPC en entornos Cloud

CloudMPL:a domain specific language for describing management policies for an autonomic cloud infrastructure

To benefit from the advantages that Cloud Computing brings to the IT industry, management policies must be implemented as a part of the operation of the Cloud. Among others, for example, the specification of policies can be used for the management of energy to reduce the cost of running the IT system or also for security policies while handling privacy issues of users. As cloud platforms are large, manual enforcement of policies is not scalable. Hence, autonomic approaches for management policies have recently received a considerable attention. These approaches allow specification of rules that are executed via rule-engines. The process of rules creation starts by the interpretation of the policies drafted by high-rank managers. Then, technical IT staff translate such policies to operational activities to implement them. Such process can start from a textual declarative description and after numerous steps terminates in a set of rules to be executed on a rule engine. To simplify the steps and to bridge the considerable gap between the declarative policies and executable rules, we propose a domain-specific language called CloudMPL. We also design a method of automated transformation of the rules captured in CloudMPL to the popular rule-engine Drools. As the policies are changed over time, code generation will reduce the time required for the implementation of the policies. In addition, using a declarative language for writing the specifications is expected to make the authoring of rules easier. We demonstrate the use of the CloudMPL language into a running example extracted from a management energy consumption case study

CodeCloud: A platform to enable execution of programming models on the Clouds

This paper presents a platform that supports the execution of scientific applications covering different programming models (such as Master/Slave, Parallel/MPI, MapReduce and Workflows) on Cloud infrastructures. The platform includes (i) a high-level declarative language to express the requirements of the applications featuring software customization at runtime, (ii) an approach based on virtual containers to encapsulate the logic of the different programming models, (iii) an infrastructure manager to interact with different IaaS backends, (iv) a configuration software to dynamically configure the provisioned resources and (v) a catalog and repository of virtual machine images. By using this platform, an application developer can adapt, deploy and execute parallel applications agnostic to the Cloud backend.The authors wish to thank the financial support received from both the Spanish Ministry of Economy and Competitiveness to develop the project "Servicios avanzados para el despliegue y contextualizacion de aplicaciones virtualizadas para dar soporte a modelos de programacion en entornos cloud", with reference TIN2010-17804.Caballer Fernández, M.; Alfonso Laguna, CD.; Moltó, G.; Romero Alcalde, E.; Blanquer Espert, I.; García García, A.
