OSBConf 2015 | Vm backup beyond bacula by christian theune

Top-of-rack switches managed with the same tools as servers With Cumulus Linux, top-of-rack switches can be managed with the same Linux tools as the servers. But until now, the out-of-band management switch was still separate, limited to traditional network switches and their unique tools. With the new Cumulus RMP (Rack Management Platform) operating system for out-of-band switches, Linux can now be used to manage the entire rack. That means the tools you use for servers and for switches running Cumulus Linux can also be used for the out-of-band switch starting with the Penguin Computing Arctica 4804ip. This presentation helps you to learn more about using Linux to manage the whole rack, including details on: Open development Consistent interface Access to local network data for operations Integrated tools Ease of automation

Apache Mesos Distributed Computing Talk

brandongulla

This document provides an agenda for a talk on Apache Mesos, a distributed systems kernel that provides resource management and helps to abstract cluster resources. The talk discusses why distributed computing is hard, how Mesos helps by turning servers into a single large computer and improving multi-tenancy. It also covers Mesos history, how it works, examples of Mesos in production use, and alternatives to writing custom frameworks like Marathon.

Making Clouds: Turning OpenNebula into a Product

What does it takes to bring innovations like private clouds to small and medium enterprises? In the course of this talk we will present our experience in creating a self-service toolkit for creating a complete virtualization and cloud platform based on OpenNebula, as well as our experience gathered in tens of installations of all sizes. From scalable storage (with benchmarks!) to autonomic optimization, we will present what in our view is needed to bring private clouds to everyone, what components and additions we created to better solve our customers’ problems (from replacing industrial control systems to medium scale virtual desktop infrastructures), and why OpenNebula has been chosen over other competing cloud toolkits.

Elastic virtualization using the popular OpenStack platform is for real. While Sysadmins and DevOps professionals fully embrace these new developments, managing them is still a challenge. Adding layers of abstraction for compute, network and storage resources further increases complexity. Resource sharing, the fully dynamic creation of networks, virtual machines and recently Linux containers inside the framework also increases the challenge of managing these already complex systems. This presentation will provide insights on how to optimize the monitoring and management of OpenStack "from the bottom up", and from front to back to efficiently manage and troubleshoot OpenStack environments using API monitoring techniques and best of breed OpenSource tools such as Icinga 2.4, OpenStack API, Fuel, BoxSpy, OpenTSDB and others.

Contrail Virtual Execution Platform

The Contrail Virtual Execution Platform (VEP) allows Cloud administrators to manage data centers and monitor the usage of resources. Users can manage their distributed applications on IaaS Cloud providers under the control of Service Level Agreements (SLA). VEP applications are packaged in the standard OVF format and they are deployed inside Constrained Execution Environments (CEE) derived from the SLA, to support the specification of SLA contracts between users and providers. These CEE environments allow to define constraints concerning virtual hardware performance, localization and affinity allowing the administrator to configure the monitoring system in order to feed external SLA enforcement services. VEP integrates elasticity management capabilities which can be controlled by external SLA enforcement services. A resource allocator service is integrated to dispatch the virtual components on the physical resources of the provider in accordance with the SLA terms. The first version of VEP is currently implemented on OpenNebula. This talk presents the implementation of VEP on OpenNebula and discusses some implementation choices such as the resource allocator.

Welcome talk unleashing the future of open-source enterprise cloud computing

The OpenNebula Project has come a long way since the first “technology preview” of OpenNebula almost six years ago. During these years we’ve witnessed the rise and hype of the Cloud, the birth and decline of several virtualization technologies, but specially the encouraging and exciting growth of OpenNebula; both as a technology and as an active and engaged community. As a meeting point for OpenNebula users, developers, administrators, builders, integrators and researchers, this Conference represents an opportunity to look back at how the project has grown in the last six years, and to give a peek at what to expect from the project in the near future.

Community Clouds from Scratch

Cloud Computing represents a radical change in the way we organize and use computing resources and storage. The scientific and academic communities face the challenge of not only adapting their procedures to this new paradigm, but also contributing Cloud Computing development and leading its evolution towards open, secure and interoperable computing infrastructures, which will playing a key role in the community clouds paradigm. The Spanish MEGHA initiative promotes and coordinates contributions to cloud computing R&D, education and management made by institutions affiliated with RedIRIS [7] in Spain. In the first phase (2010–2012), MEGHA validated federated cloud platforms using Opennebula and OCCI [10] to streamline the use of cloud technologies among R&E service centers. Representative infrastructure providers (CESCA, CESGA, PIC), middleware providers (OpenNebula, RedIRIS, OSAmI-Commons) and users (UAB, UOC, UM) together with intermediate/identity/brokers resources (RedIRIS) joined efforts to demonstrate the viability of this approach. The results stimulated the development of use cases including e-learning platforms on demand (Learning Apps project), a distributed HPC platform (e-Science), and Virtual Labs (VDI) in a hybrid scenario (Academic services). Next Steps? As next goal, the Spanish research and academic community is working to assess the possibilities of creating a productive Infrastructure Cloud Computing service within member institutions. With this new approach new challenges appear: Federated user authentication and authorization mechanisms. Brokering architecture scenario. Secure VM image distribution and validation. A federated cloud accounting system integrating the accounting records of multiple cloud managers and supporting federated cloud governance. Monitoring and notification of unpredictable changes in availability and readability status. Security Policies and Service Level Agreements (SLA’s).

CentOS and OpenNebula, a Perfect Match

OpenNebula is a great cloud orchestration and management tool, characterised by its flexibility, durability and focused feature matrix. A feature matrix that is driven largely by real world problem scenarios and real world feedback : something that has been the focus of CentOS project as well. From large scale deployment automation to patch management and state control, the CentOS Project aims to solve real world problems faced by the people who run infrastructure : The Sysadmins administrators and operations teams. During this talk, I will share why OpenNebula and CentOS Linux are a perfect match and go into some user stories that demonstrate this relationships success in real world scenarios.

Razor: A fresh look at provisioning by David Lutterkort

Razor is a flexible provisioning tool that makes it easy to control how machines are built based on rules and policies. It maintains an inventory of nodes and their hardware characteristics, gathered by booting each node into a discovery image. Razor is an opinionated tool that focuses narrowly on provisioning, but makes it easy to hand off a node after installation to a configuration management system like Puppet to perform more complicated setup tasks and for ongoing maintenance.This talk will give an overview of Razor's capabilities and provide some hands-on examples about its use, including how Razor can be used to build an OpenStack cloud using Puppet Labs' OpenStack modules.

Whether you're deploying Hadoop and Big Data workloads, OpenStack at High Availability, or your application. Juju makes these tasks and more easy to manage, scale, and repeat - doesn't matter if you're on a public cloud, private cloud, or building your own cloud on metal. In this talk we'll deploy OpenStack and Hortonworks Hadoop on bare metal and in a cloud, discuss what/how Juju works, and explore other possible solution/workloads which Juju can manage. Juju is Canonical's next generation cloud orchestration tool provided as free and open source. Written in Golang, it provides fast orchestration for any workload. Juju makes use of an orchestration node in the environment which marshalls events that occur in the environment and dispatches them to the extremely lightweight agents installed on each machine. The orchestration node also acts as the entry point for communication to the environment via a websocket API. The CLI and the GUI (both open source software) use it for communication to an environment.

Live migration: pros, cons and gotchas -- Pavel Emelyanov

OpenVZ

Live migrating containers has pros like load balancing and updating hardware, but also cons. It is complex due to needing to save a container's state, transfer it, and restore it on another host while tasks are frozen. This can be done with memory pre-copy, where memory is copied iteratively while tasks run, or post-copy, where memory is transferred after tasks resume. P.Haul uses CRIU to handle the critical state save and restore functions needed for live migrating containers between hosts.

My sql with enterprise storage

Caroline_Rose

This document discusses using logical volume management (LVM) with MySQL for enterprise storage. Some key points include: - LVM allows virtualizing storage into logical volumes mapped to physical disks, enabling features like snapshots and clones for backups and replication. - Snapshots provide point-in-time copies while clones are writable copies, both using copy-on-write to avoid duplicating data. - Backing up MySQL with snapshots is fast, and recovery involves reverting the logical volumes rather than restoring files. Replication slaves can be quickly recloned from snapshots. - With shared storage, replication slaves maintain the same blocks as the master for efficient scaling and resyncing slaves by recloning

It covers topics such as the need for backups, different types of backups like full, incremental, logical and raw backups. It also discusses storing backups, testing backups, backup consistency, and good backup practices. The document emphasizes that backups are important to protect valuable data from disasters, but also stresses the importance of testing recovery procedures.

BGOUG "Agile Data: revolutionizing database cloning'

The document discusses using data virtualization to address the constraint of data in DevOps workflows. It describes how traditional database cloning methods are inefficient and consume significant resources. The solution presented uses thin cloning technology to take snapshots of production databases and provide virtual copies for development, QA, and other environments. This allows for unlimited, self-service virtual databases that reduce bottlenecks and waiting times compared to physical copies.

Denver devops : enabling DevOps with data virtualization

This document discusses how data constraints can limit DevOps efforts and proposes a solution using virtual data and thin cloning. It notes that moving and copying production data is challenging due to storage, personnel and time requirements. This typically results in bottlenecks, long wait times for environments, code check-ins and production bugs. The solution presented is to use a data virtualization platform that can take thin clones of production data using file system snapshots, compress the data and share it across environments through a centralized cache. This allows self-service provisioning of database environments and accelerates DevOps processes.

郁萍王

MySQL Enterprise Backup provides fast, consistent, online backups of MySQL databases. It allows for backing up InnoDB and MyISAM tables while the database is running, minimizing downtime. The tool takes physical backups of the data files rather than logical backups, allowing for very fast restore times compared to alternatives like mysqldump. It supports features like compressed backups, incremental backups, and point-in-time recovery.

MySQL Infrastructure Testing Automation at GitHub

Ike Walker

The database team at GitHub is tasked with keeping the data available and with maintaining its integrity. Our infrastructure automates away much of our operation, but automation requires trust, and trust is gained by testing. This session highlights three examples of infrastructure testing automation that helps us sleep better at night: - Backups: scheduling backups; making backup data accessible to our engineers; auto-restores and backup validation. What metrics and alerts we have in place. - Failovers: how we continuously test our failover mechanism, orchestrator. How we setup a failover scenario, what defines a successful failover, how we automate away the cleanup. What we do in production. - Schema migrations: how we ensure that gh-ost, our schema migration tool, which keeps rewriting our (and your!) data, does the right thing. How we test new branches in production without putting production data at risk.

Open west 2015 talk ben coverston

bcoverston

Ben Coverston gave a presentation on full stack high availability in an eventually consistent world. He discussed how traditional databases don't scale well and are not built for failure. Eventual consistency means queries may return different results and consistency is not guaranteed. The CAP theorem states you can only achieve two of consistency, availability, and partition tolerance. Spark provides a faster alternative to Hadoop MapReduce for real-time analytics. Cassandra allows for distributed counting through its use of counters to provide near real-time counts while compromising consistency during network partitions. The lambda architecture separates real-time and batch processing to provide both low latency queries and accurate historical data.
