This document discusses dockerizing Apache CloudStack. It notes that dockerizing CloudStack provides deployment simplicity, allows faster proof-of-concept deployments, and makes CloudStack easier to distribute. Some challenges include constraints around systemvm disk mounting and testing packages. The document demonstrates deploying CloudStack components like the simulator, Marvin, and CloudMonkey using Docker containers with links and volumes. It finds that dockerizing CloudStack is faster than traditional deployment but requires bash scripts and image sizes are large. Overall dockerizing CloudStack provides benefits but could be improved by using smaller base images and deploying from a WAR file.

DevOps Hackathon - Session 1: VagrantAntons Kranga

More than Applications: (Ab)using Docker to Improve the Portability of Everyt...Dexter Horthy

Slides from Docker Los Angeles meetup on 4/18/2018. Most of us have used Docker to ship application code from a laptop or a continuous integration system to a production server. But why stop there? In this talk, we will discuss some little known and less commonly understood ways to use Docker to increase portability of everything else. For example, Docker can be used as a portable apt repository to install packages on any server, not only in a container. Another example is to use Docker (and LinuxKit) as a way to distribute Docker images when a registry isn’t available. *About the Speaker:* Dex Horthy, is a Core Engineer at Replicated. He has spent the last year designing and writing production grade enterprise software for the Replicated platform, including container orchestration runtimes and custom integrations into the Kubernetes and Docker APIs.

SDPHP - Percona Toolkit (It's Basically Magic)Robert Swisher

Vagrant to-aws-flowKimberly Macias

Vagrant can be used to create consistent development environments that match production. This allows developers to develop locally yet still have access to all production dependencies. The presenter recommends using Vagrant to provision local development environments that match the OS used in production AWS environments. Developers can then use the same configuration management tools and processes locally and in production. Code is deployed from Vagrant environments to AWS, ensuring development and production remain consistent. A demo is provided to stand up identical local and AWS environments and deploy code between them.

DevOps hackathon Session 2: Basics of ChefAntons Kranga

The document discusses infrastructure provisioning using Chef. It explains that Chef uses a declarative approach where you describe the desired state rather than how to achieve it. Cookbooks contain recipes that describe resources to bring a VM to the specified state. Cookbooks are repeatable, testable units that can install packages, configure services, create users and templates. Vagrant and Chef are often used together, with Vagrant managing VMs and triggering Chef provisioning to install software inside VMs.

Intelligently Expanding Your Cloud EnvironmentTom Cudd

Managing a single cloud account is a challenge all by itself. Only adding more instances and services to one account can lead to challenges from keeping track of what is running to quota limits set by the providers. When you hit the logical limits of that account, expanding the footprint of your cloud strategy is more than just spinning up a new account and dropping the corporate credit card on it. Both Azure and AWS have created logical ways to organize your accounts along project, product, purpose, team, or billing boundaries. In this session, you will learn the basics of using AWS or Azure structures and hierarchy to manage the growth of your cloud ecosystem. Enjoy this introduction of AWS Organizations, Control Tower, and Policies along with an overview of Azure Management, Subscriptions, and Resource Groups to effectively manage your workload.

The Seven DevOps SinsTom Cudd

The document discusses the seven DevOps sins - lust, gluttony, greed, sloth, wrath, envy, and pride. It provides examples for each sin in the context of DevOps practices, such as choosing shiny new technologies over boring reliable ones for lust, taking on too many projects at once for gluttony, prioritizing revenue over quality for greed, allowing idle time for sloth, getting interrupted by urgent tasks for wrath, comparing yourself to other more successful teams for envy, and refusing to explain DevOps practices to others for pride. The document advocates for learning from failures, experimenting, adapting, caring about others, and changing yourself rather than trying to change the world.

Destroying DevOps Culture Anti-PatternsTom Cudd

DevOps is a set of practices and culture that an organization uses to deliver operational excellence. DevOps should not just be teams, tools, or things you hire a consultant for. In a development or operations practice, an anti-pattern is a behavior that crops up, which hinders the best efforts of a project or organization. Learn to how to identify these DevOps Culture Anti-patterns, and then attack them in specific ways to resolve these issues.

How the company portal evolved the dev ops journeyTom Cudd

Often times, internal company portals and intranets are cast away to the relegated trash heaps of technical debt and enforced homepages. So how did a “hand-crafted artisanal server” with code “carefully, expertly, and manually placed atop the multi-tiered system” turn into a bastion of usability, functionality, and a crowning achievement of DevOps processes within an organization? The journey into these methods shaped the architectural decisions of our internal systems, and the portal shaped the processes we used to mature our methods. Our portal has become a Passport into the company communications, where any part of the business can learn more about any other area. In our travels, successes, and failures, we educate on the following topics: High recoverability vs. high availability Single source of authentication vs. bespoke directories Shared knowledge vs. hero culture Continuous integration vs. manual processes Collaborative architecture vs. siloed decisions Blameless response vs. finger pointing Configuration management vs. runbooks

Respond to and troubleshoot production incidents like an saTom Cudd

So it's 4 AM and you just got a call from a panicked executive that the system is down! Oh noes! What do you do? Troubleshoot LIKE AN SA. I know "Systems Administrator" is not the cool industry term anymore, but that mentality for fixing the big live problem, like RIGHT NOW can still help today. You're probably in the job you're in because you're AWESOME at figuring out what's wrong and fixing problems. But your projects have grown, your team has grown, and the expectations grow with them. How do you deal with these new found responsibilities? LIKE AN SA. There are some simple processes you can put in place to help make your life easier. We'll discuss a framework for incident response, a step-by-step guide for troubleshooting production issues, and how to then learn from these outages to prevent problems from happening again.

An extended explanation of caching version 2Tom Cudd

Caching can be like regex. If you've got a problem and not a clear understanding of what you're trying to solve, you're going to end up with two problems. Understanding the mechanisms and types of caching possible from end user browsers down to in-memory databases can help clarify just what problem each layer of caching is designed to solve. Learn about what to cache, how to cache, and when to introduce caching into the mix of what you're building out. We'll talk about how to use CDN's, in memory, on disk, and cloud solutions when having to scale your applications with a caching solution.

Webinar Recording: https://www.panagenda.com/webinars/hcl-nomad-web-best-practices-and-managing-multiuser-environments/ HCL Nomad Web is heralded as the next generation of the HCL Notes client, offering numerous advantages such as eliminating the need for packaging, distribution, and installation. Nomad Web client upgrades will be installed “automatically” in the background. This significantly reduces the administrative footprint compared to traditional HCL Notes clients. However, troubleshooting issues in Nomad Web present unique challenges compared to the Notes client. Join Christoph and Marc as they demonstrate how to simplify the troubleshooting process in HCL Nomad Web, ensuring a smoother and more efficient user experience. In this webinar, we will explore effective strategies for diagnosing and resolving common problems in HCL Nomad Web, including - Accessing the console - Locating and interpreting log files - Accessing the data folder within the browser’s cache (using OPFS) - Understand the difference between single- and multi-user scenarios - Utilizing Client Clocking
