OSDC 2018 | Scaling & High Availability MySQL learnings from the past decade+ by Colin Charles

VMWare is a common hypervisor choice in large organizations, and it comes with a zoo of additional tools, options and licenses. But once you add a little bit of OpenSource to the mix, things start to get interesting. There are open APIs which integrate well with Tools like Ansible and InSpec. So it is easy to write your own scripts to verify a configuration or harden a ESX host. We will show you, how we automated our deployment, what problems we encountered and how we added some nice features.

Deploying stateful applications such a Wordpress and Jenkins on top of Kubernetes or any other container orchestrator can be a challenging task. In this context, Rook will be used to showcase how to automatically manage the volume's lifecycle through the its Kubernetes operators (operator pattern approach) by leveraging the recently added CSI GA support.

Opcito Technologies is a proud partner with Kubernetes, an open-source system for container orchestration. We will be talking about: • Features of Kubernetes 1.6 • RBAC Configurations • RBAC Use Cases • Running Prometheus in Kubernetes • Prometheus Operator - Deployment, Cluster & Service Monitoring

The document provides information and tips for preparing for the CKA (Certified Kubernetes Administrator) exam. It outlines what to know prior to taking the exam such as it being offered by CNCF, the exam format, curriculum covered, and required equipment. It recommends practicing Linux CLI, kubectl commands, getting familiar with Kubernetes documentation, examples and APIs. Suggested study methods include using Minikube, Kube-Ansible, online courses, and YouTube videos. Registering for the exam and free learning materials are also mentioned.

Fabric8 is a tool that aims to reduce the gap between development and operations by allowing developers to deploy and manage applications from development through production. It uses profiles and containers to deploy applications in a unified way across environments. Fabric8 supports various containers like Tomcat, Docker, and OpenShift. It includes integrated monitoring via Hawt.io and a shell to help with scripting and diagnostics. The goal is to make developers more self-sufficient by enabling them to take on more operations tasks in their own sandboxes.

Kubernetes currently has two load balancing mode: userspace and IPTables. They both have limitation on scalability and performance. We introduced IPVS as third kube-proxy mode which scales kubernetes load balancer to support 50,000 services. Beyond that, control plane needs to be optimized in order to deploy 50,000 services. We will introduce alternative solutions and our prototypes with detailed performance data.

Project Harbor provides an enterprise-grade private registry with features for user management, image replication, security, and integration with systems like LDAP. It aims to help organizations securely manage the distribution and storage of container images.

The document provides best practices for deploying SUSE CaaS Platform. It discusses requirements like hardware needs, software subscriptions required, and support options. It covers planning and sizing considerations like cluster topology and disk space needs. Deployment best practices include steps like preparing the infrastructure, installing base software, verifying the infrastructure, installing CaaS Platform, and deploying Kubernetes addons. Testing and operations topics like monitoring, logging, backups are also covered.

The document provides an overview of Red Hat OpenShift Enterprise, which is Red Hat's container application platform. It discusses key OpenShift concepts like Docker containers, Kubernetes cluster management, projects for sandboxing environments, image builds, deployments, services and routes. It also summarizes added value of OpenShift over plain Docker and Kubernetes through features like templates, web console, multi-language support, automated builds and deployments, and enterprise capabilities.

Service Discovery in kubernetes is all about how services of kubernetes get discovered internally and externally. How does a single POD communicate to another POD the within the cluster and how does a user request reach to a specific POD in the cluster? These are some questions that are answered by this TOPIC.

In this video from the Docker Workshop at ISC 2015, Christian Kniep from QNIB Solutions shows how he uses Docker in his efforts to provide a HPC software stack in a box, encapsulating each layer in the HPC stack within a Linux Container.

Presentation delivered at LinuxCon China 2017. Rethinking the Operating System. A new wave of Operating Systems optimized for containers appeared on the horizon making us excited and puzzeled at the same time. "Why do we need anything different for containers when traditional OSs served us well in the last 25+ years?" "Isn't Kubernetes just another package to install on top of my favorite distro?"" Will this obsolete my whole infrastructure?" are some of the questions this talk will shed some light on. Explore the journey SUSE made in rethinking the OS: From a conservative linux distribution to a platform that goes hand in hand with the needs of Microservices. You will get an insight at what lessons were learned during the intense development effort that lead to SUSE Containers as a Service Platform, how the obstacles along the way were lifted and why "Upstream first" is - and should always be - the rule.

In this deck from the Docker Workshop at ISC 2015, Andreas Schmidt from Cassini Consulting describes Docker in a Nutshell "As the newest flavor of Linux Containers, Docker gained a lot of momentum in the last 12 months. With a very convenient and open API-driven architecture Docker is able to help decrease the complexity of operations and increase the productivity of computation. During the last two years Andreas, Christian, and Wolfgang gained a lot of experience with Docker and were thrilled by its possible impact early on. Andreas started working with Docker in mid-2013 and is interested in developing tools for solving Enterprise IT requirements on networking and security. In 2014 he held talks and workshops about these topics. Christian started using Docker in 2013 to virtualize a complete HPC cluster stack and since then held multiple talks about how Docker might impact HPC. Wolfgang and his partner Burak Yenier introduced Docker as a corner-stone of the UberCloud Marketplace to drastically improve and simplify access to HPC cloud resources. UberCloud just announced their new containers for computational fluid dynamics software like Fluent, STAR-CCM+ and OpenFOAM."

Presentation delivered at LinuxCon China 2017. Operating systems need to move faster without sacrificing stability. New hardware, new software features, and bugfixes are making it into distribution components every day. To maintain stability, packagers and distribution developers are looking toward lessons learned in the DevOps movement to implement Continuous Integration/Continuous Delivery (CI/CD) workflows that provide quicker test feedback to developers. This talk highlights some of the coming trends in Fedora such as: streamlined base package sets, userspace applications delivered as containers, continuous validation of individual distro components and the distro as a whole, and collaboration with the CentOS Project.

Have you ever tried Java on AWS Lambda but found that the cold-start latency and memory usage were far too high? In this session, we will show how we optimized Java for serverless applications by leveraging GraalVM with Quarkus to provide both supersonic startup speed and a subatomic memory footprint.

This document discusses potential use cases for Kubernetes and provides examples of deploying serverless/Function as a Service (FaaS) workloads and blockchain databases on Kubernetes. It introduces OpenFaaS as an easy way to deploy FaaS on Kubernetes and deploy a demo Ethereum blockchain on Kubernetes to illustrate how blockchain concepts map to Kubernetes components. The document encourages finding a new use case in your organization to start using Kubernetes and provides resources for learning more about deploying Kubernetes.

Given at O'Reilly Velocity London in October 2017, this tutorial focuses on the current best practices for MySQL High Availability.

Best practices for MySQL/MariaDB Server/Percona Server High Availability - presented at Percona Live Amsterdam 2016. The focus is on picking the right High Availability solution, discussing replication, handling failure (yes, you can achieve a quick automatic failover), proxies (there are plenty), HA in the cloud/geographical redundancy, sharding solutions, how newer versions of MySQL help you, and what to watch for next.

The MariaDB/MySQL world is full of tradeoffs, and choosing a high availability (HA) solution is no exception. This session aims to look at all the alternatives in an unbiased way. Preference is of course only given to open source solutions. How do you choose between: asynchronous/semi-synchronous/synchronous replication, MHA (MySQL high availability tools), DRBD, Tungsten Replicator, or Galera Cluster? Do you integrate Pacemaker and Heartbeat like Percona Replication Manager? The cloud brings even more fun, especially if you are dealing with a hybrid cloud and must think about geographical redundancy. What about newer solutions like using Consul for MySQL HA? When you’ve decided on your solution, how do you provision and monitor these solutions? This and more will be covered in a walkthrough of MySQL HA options and when to apply them.

MariaDB is like the "new" MySQL, and its available everywhere. This talk was given at LinuxCon Europe in Dublin in October 2015. Learn about all the new features, considering the release was just around the corner. Changes in replication are also very interesting

Presented at the Tokyo MariaDB Server meetup in July 2016, this is an overview of what you can see and use in MariaDB Server 10.1, but more importantly what is planned to arrive in 10.2

Scalability with MariaDB and MaxScale talks about MariaDB 10, and MaxScale, a pluggable router for your queries. These are technologies developed at MariaDB Corporation, made opensource, and will help scale your MariaDB and MySQL workloads

Meet MariaDB 10.1 at the Bulgaria Web Summit, held in Sofia in February 2016. Learn all about MariaDB Server, and the new features like encryption, audit plugins, and more.

MariaDB 10: A MySQL Replacement. Current up to 10.0.9, right before the 10.0.10 GA release presented the weekend before the release in Hong Kong, at the Hong Kong Open Source Conference.

The myriad reasons why you want to use MariaDB over stock MySQL. Current up to MariaDB 5.3, and presented at Percona Live London 2011.

This document provides an overview of MariaDB 10 and the MariaDB Foundation. It discusses the history and development of MariaDB, including key features added in versions 5.1 through 10.0 such as new storage engines, performance improvements, and features backported from MySQL. It outlines the goals of MariaDB to be compatible with MySQL while adding new features, and describes the community-led development model. The roadmap aims to have MariaDB be a drop-in replacement for MySQL 5.6 by releasing version 10.1.

There are many Galera Cluster distributions and sometimes differences are well worth noting. We get a lot of queries about which Galera Cluster to use, or why one should use one distribution over the other. Learn about Galera Cluster with MySQL 5.7 from Codership, and we’ll compare it with Galera Cluster 4 with MariaDB 10.4, and Percona XtraDB Cluster 5.7 with Galera 3. This is also the webinar where we preview Galera Cluster 4 with MySQL 8.0 as well as compare it with the preview release of Percona XtraDB Cluster 8.0. Overall, learn why distributions exists, and how you can get the most out of your Galera Cluster experience.

This is my third iteration of the talk presented in Tokyo, Japan - first was at a keynote at rootconf.in in April 2016, then at the MySQL meetup in New York, and now for dbtechshowcase. The focus is on database failures of the past, and how modern MySQL / MariaDB Server technologies could have helped them avoid such failure. The focus is on backups and verification, replication and failover, and security and encryption.

The document summarizes the history and current state of the MySQL database server ecosystem. It discusses the origins and development of MySQL, MariaDB, Percona Server, and other related projects. It also describes some of the key features and innovations in recent versions of these database servers. The ecosystem is very active with contributions from many organizations and the future remains promising with ongoing work.

MySQL is a unique adult (now 21 years old) in many ways. It supports plugins. It supports storage engines. It is also owned by Oracle, thus birthing two branches of the popular opensource database: Percona Server and MariaDB Server. It also once spawned a fork: Drizzle. Lately a consortium of web scale users (think a chunk of the top 10 sites out there) have spawned WebScaleSQL. You're a busy DBA having to maintain a mix of this. Or you're a CIO planning to choose one branch. How do you go about picking? Supporting multiple databases? Find out more in this talk. Also covered is a deep-dive into what feature differences exist between MySQL/Percona Server/MariaDB/WebScaleSQL, how distributions package the various databases differently. Within the hour, you'll be informed about the past, the present, and hopefully be knowledgeable enough to know what to pick in the future. Note, there will also be coverage of the various trees around WebScaleSQL, like the Facebook tree, the Alibaba tree as well as the Twitter tree.

Lets learn from MySQL failures at scale, because we tie in the topic of High Availability, in where people are thinking about geographical redundancy, and even things like automatic failover. In the talk there will be case study material, e.g. where automatic failure caused a site to go offline, where a social network started of with not using fully automated failovers but evolved, etc. How is the MySQL world making things better, for example by allowing you to use semi-synchronous replication to run fully scalable services. The talk starts off with an even almost stupid example of how a business died due to incorrect MySQL backup procedures. It will go on to talk about security and encryption at rest as well. So a mix of problems from the field, big “fail whales”, and how you should avoid them by properly architecting solutions.

MariaDB started life as a database to host the Maria storage engine in 2009. Not long after its inception, the MySQL community went through yet another change in ownership, and it was deemed that MariaDB will be a complete database branch developed to extend MySQL, but with constant merging of upstream changes. The goal of the MariaDB project is to ensure that everyone is part of the community, including employees of the major steering companies. MariaDB also features enhanced features, some of which are common with the Percona Performance Server. Most importantly, MariaDB is a drop-in replacement and is completely backward compatible with MySQL. In 2010, MariaDB released 5.1 in February, and 5.2 in November – two major releases in a span of one calendar year is a feat that was achieved! DBAs and developers alike will gain an introduction to MariaDB, what is different with MySQL, how to make use of the feature enhancements, and more.

You're a busy DBA thinking about having to maintain a mix of this. Or you're a CIO planning to choose one branch over another. How do you go about picking? Supporting multiple databases? Find out more in this talk. Also covered is a deep-dive into what feature differences exist between MySQL/Percona Server/MariaDB Server. Within 20 minutes, you'll leave informed and knowledgable on what to pick. A base blog post to get started: https://www.percona.com/blog/2017/11/02/mysql-vs-mariadb-reality-check/

This was a short 25 minute talk, but we go into a bit of a history of MySQL, how the branches and forks appeared, what's sticking around today (branch? Percona Server. Fork? MariaDB Server). What should you use? Think about what you need today and what the roadmap holds.

MariaDB is a community developed branch of MySQL that is feature enhanced and backward compatible. It aims to be a 100% drop-in replacement for MySQL that is stable, bug-free, and released under the GPLv2 license. Major releases of MariaDB include new storage engines like XtraDB and Aria, as well as new features for performance, scalability, and compatibility. MariaDB is developed as an open source project and supported by Monty Program and other community contributors and service providers.

MySQL is still hot, with Percona XtraDB Cluster (PXC) and MariaDB Server. Welcome back post-pandemic to see what is on offer in the current ecosystem. Did you know that Amazon RDS now uses semi-sync replication rather than DRBD for multi-AZ deployments? Did you know that Galera Cluster for MySQL 8 is much more efficient with CLONE SST rather than using the xtrabackup method for SST? Did you know that Percona Server continues to extend MyRocks? Did you know that MariaDB Server has more Oracle syntax compatibility? This and more will be covered in the session, while short and quick, should leave you wandering to discover new features for production.
