Backroll is not only a production-grade KVM backup solution. It is also being integrated inside Apache Cloudstack using the Backup and restore framework. Pierre and Quentin will show how it works, the feature list, and how the integration has been made. Quentin is in charge of DIMSI custom developments on Apache Cloudstack deployment : customer portal, backup solution. On a daily basis, he helps our customers and our developers to use and embrace Devops methodology, by building CI/CD pipelines (GitLab, Azure Devops), dockerizing apps and automate things as much as possible... When not DevOps'ing, Quentin loves to binge watch series and movies, play with his cat "Boogie" and is a crazy fan of street food. Grégoire is a software architect who spends most of his time designing infrastructure applications and CRM systems, on-premise or multi-cloud based. He’s been using Apache Cloudstack for many years, and likes to keep knowledge and data outside black-boxes Father of 4 children, you can meet him in Southern Brittany, sailing Hobbie Cat or supporting Lorient football club at Moustoir stadium. Pierre is in charge of Backroll integration inside Cloudstack. Pierre has a proven track record of successful c# and Java projects. When not playing with his keyboard, Pierre is surfing, WingFoiling or bodyboarding on Brittany coast. ----------------------------------------- CloudStack Collaboration Conference 2022 took place on 14th-16th November in Sofia, Bulgaria and virtually. The day saw a hybrid get-together of the global CloudStack community hosting 370 attendees. The event hosted 43 sessions from leading CloudStack experts, users and skilful engineers from the open-source world, which included: technical talks, user stories, new features and integrations presentations and more.

MariaDB is the new open source drop-in replacement for MySQL that has been adopted by IBM for use on Power Linux and IBM i. ZendDBi is the installer provided by Zend for installation of MariaDB on the IBM i. In this session we'll show how to use ZendDBi to install MariaDB and provide some important tips for post-installation. We'll also demonstrate troubleshooting some common installation issues. While most installations of MariaDB are trouble free, the troubleshooting procedures will give us a chance to understand a bit more about the operation of MariaDB on the IBM i. It'll also give us the opportunity to explore some concepts on IBM i that may not be familiar to some RPG programmers.

Some of the best businesses today are deploying their code dozens of times a day. How? By making heavy use of automation, smart tools, and repeatable patterns to get process out of the way and keep the workflow moving. Come to this session to learn how you can do this too, using services such as AWS OpsWorks, AWS CloudFormation, Amazon Simple Workflow Service, and other tools. We'll discuss a number of different deployment patterns, and what aspects you need to focus on when working toward deployment automation yourself.

To simplify deploying and managing modern applications, enterprises have been combining the benefits of hyperconverged infrastructure (HCI) with the performance and scale of a NoSQL database — and the results have been remarkable. With this combination, IT organizations have experienced more agility, improved reliability, and better application performance. Watch this on-demand webinar where you’ll learn specifically how VMware HCI with DataStax Enterprise (DSE) and Apache Cassandra™ are transforming the enterprise.

The first Virtual Machine should be installed and have the BIND (DNS) server installed on it. While you do not own any address space/ name space your name server should manage the following domains: The name server should answer queries for this domain. In addition to the saffioti.org.au zone, a zone should be set up for the reverse zone – the reverse zone would be whatever the address range is of your virtual machine. You should do some research on how Bind handles reverse zones.

Corporate and higher education. Two industries that, in the past, have had a clear divide with very little crossover. The difference in goals, learning styles and objectives paved the way for differing learning technologies platforms to evolve. Now, those stark lines are blurring as both sides are discovering they have content that’s relevant to the other. Join Tammy Rutherford as she walks through the pros and cons of corporate and higher ed collaborating. And the challenges of these different technology platforms working together for a brighter future.
