Migrating a Large Fortune 100 Healthcare Company to Kubernetes in 7 monthsKonveyor Community

Watch the presentation: https://youtu.be/E3LeAmH6Ems At the beginning of 2019, Chris Nuland and team were tasked with migrating a large mesosphere DC/OS cluster with hundreds of running containers to Kubernetes for a large fortune 100 healthcare company. One of the key challenges with this migration was the need to finish it within a 7 month timeframe to allow the sunsetting of DC/OS before the cluster’s end of life. In conjunction with this migration, there was also the need to containerize a couple hundred applications and deploy them into the newly built cluster. These tasks were completed in the desired time frame using a variety of migration and onboarding techniques, including the use of a few migration tools, like pathfinder, that would eventually be part of the Konveyor suite of applications. This presentation will go over many of the challenges of that migration, how certain tooling aided in the process, and how the process would look differently now given many of the migration tooling advantages found in the Konveyor suite of applications. Presenter: Christopher Nuland, Architect at Red Hat

Automate Workflows With The Open-source Cloud-native Tool Boomerang FlowKonveyor Community

In the cloud-native workflow automation world, there are many great open-source projects such as Argo, Airflow, and Brigade. These tools require technical expertise to be used by business users, or they are aligned with a specific use case such as CI/CD. Boomerang Flow is an alternative tool that is usable by a business user but also provides an extensible framework developers can use for new use cases. It aims to replace Robotic Process Automation flows, which don’t necessarily need to be full-blown bots. And it doesn’t try to tackle use cases such as screen-scraping legacy green text applications. Instead, it tries to solve the problem where enterprises are using bots to perform tasks such as receiving a service now ticket and automatically moving it to a special status or workflow queue. These types of scenarios can be automated using Boomerang Flow. And the cost of running these workflows in Kubernetes is fractions of the cost of running an RPA bot for licensing.

Mass Migrate Virtual Machines to Kubevirt with Tool Forklift 2.0Konveyor Community

There are 6Rs that can help you have Cloud-native workloads running in your Kubernetes deployments: Refactor, Replatform, Rehost, Retire, Retain or Repurchase. Rehosting virtual machines provides less friction than others, while still providing some advantages. One of those advantages being that you can have workloads you don't want to or cannot containerize yet sit alongside your containers through KubeVirt. In this meetup, we'll show you how Forklift 2.0 makes it easy to move them to their new home. And explain why this is a small step for your workloads but a giant leap on your path to the cloud. Presenters: Miguel Pérez Colino, Senior Principal Product Manager & Fabien Dupont, Manager, Software Engineering & Senior Principal Engineer.

#bigwhale: An Unexpected Journey into Containerization @ Lockheed Martin - Pa...Docker, Inc.

2017 was a banner year for change and disruption at Lockheed Martin. Specifically Enterprise IT, moving to cloud and taking a chance on Containerization as a Service with Docker. As innovation accelerates and customer needs rapidly evolve, Lockheed Martin must become increasingly agile. Rapidly responding to customer requirements is key, and to facilitate overall business goals, Enterprise IT needs to be agile. We are experiencing software development lifecycles moving from waterfall to agile models of development. These changes are moving downstream toward Enterprise IT operations with the evolution of DevOps. In order to meet the demands of the customer and make significant progress on our cloud journey, we needed to look at changing how we manage infrastructure, how we change our IT culture and ultimately how we innovate at scale. That’s where the story of i2 labs begins. This presentation will focus on the creation of i2 labs at Lockheed Martin, which inspired and enabled people and processes to invest in Docker as a company, Containerization as a technology and DevOps as a methodology. How we went from labs testing to building Agile Development Teams to preparing to enter our BETA phase of our Enterprise Containerization as a Service to deploy applications in a consistent, repeatable, and reliable manner.

Migrating from oracle soa suite to microservices on kubernetesKonveyor Community

Watch presentation recording: https://youtu.be/cxH6WjDZc2c In this session, we’ll explore how Randoli helped a Postal Technology company migrate their payment gateway applications off Oracle SOA Suite to Camel/Springboot on Kubernetes. The primary drivers for the migration were: move to cloud-native technologies in keeping with the organizational digital transformation mandate; move away from an outdated centralized platform to a decentralized architecture for efficiency, scalability, and manageability; and very high licensing costs of the existing platform. We’ll discuss: - The high-level approach we took during the migration including architecture and design decisions. - How we used Camel/Springboot to implement the services. - Why and how we used Drools for implementing business rules. - The test-driven approach using Camel testing framework and how it helped reduce issues. - CI/CD and build process on Kubernetes. - How we tackled logging, monitoring, and tracing challenges. Presenter: Rajith Attapattu, Managing Partner & CTO @ Randoli Inc.

Operator development made easy with helmConSol Consulting & Solutions Software GmbH

- Operators are applications that extend Kubernetes to manage complex stateful applications. They use custom resource definitions (CRDs) to configure and automate tasks. - Helm is a good starting point for creating operators as it is widely used and easy to learn. Operators created with Helm can later be used to manage resources in other operators. - The demo showed creating a Helm operator from a Nginx chart and combining two operators with ArgoCD to deploy example apps based on custom resources.

Why You Should be Using Multi-stage Docker Builds in 2019Codefresh

This document discusses the benefits of using multi-stage Docker builds. It notes that traditional Docker builds result in large images containing build tools and files not needed for runtime. Multi-stage builds address this by allowing builders to create multiple stages, each producing a new image, to arrive at a minimal final image containing only what is needed for production. This improves build speed and produces more secure images by removing unnecessary components. Multi-stage builds can be used across many programming languages and are supported in continuous integration/deployment on platforms like Codefresh.

Back to the Future: Containerize Legacy ApplicationsDocker, Inc.

This document summarizes the modernization of a legacy .NET application at Fox MediaCloud using Docker Enterprise Edition (EE). The traditional Broadcast Affiliate Portal application was containerized and deployed to Azure in just 3 days. This reduced deployment time from 3 weeks to minutes and enabled redundancy and disaster recovery without downtime for security fixes or scaling. The migration demonstrated how Docker EE can help enterprises modernize applications at their own pace while controlling costs and driving innovation incrementally across their application portfolios.
