現在，有許多可將軟體搬上雲端的技術選項：Docker、微服務、serverless，不過，在搬家之前，為了降低風險，也為了避免 lock-in，你都應該先整頓既有的軟體架構。本講座說明如何以 12-factor app 思維來重構軟體架構，並且運用到 Docker、微服務、serverless 三種熱門的雲端技術身上。發表於 iThome 主辦之【Cloud Summit 2017】: http://cloudsummit.ithome.com.tw/

Vous avez certainement eu affaire à Apache Camel dans vos projects d'intégration et une grande partie se pose la question à savoir comment les styler en microservices & les embarquer dans des conteneurs ? Dans cette session nous allons voir comment on peut developper rapidement des Microservices d'intégration et passer à DevOps avec Apache Camel & Fabric8 en se basant sur docker, kubernetes & jenkins.

Distributed systems at scale have unpredictable and complex outcomes that are costly when security incidents occur. The speed, scale, and complex operations within microservice architectures make them tremendously difficult for humans to mentally model their behavior. If the latter is even remotely true how is it possible to adequately secure services that are not even fully comprehended by the engineering teams that built them. How do we realign the actual state of operational security measures to maintain an acceptable level of confidence that our security actually works. Security Chaos Engineering allows teams to proactively, safely discover system weakness before they disrupt business outcomes.

Do you always create a new Dockerfile for each new project? Do you implement your own SSL certificate logic in this Dockerfile? Do you forget to update your base image version? Do you wonder how to generate a Bill Of Material to comply with your organization requirements? Have you answered yes to any of those questions? Come and attend this talk to learn a new way to build your images, all use cases included - demos provided along the way!

No more Dockerfiles? Buildpacks to help you ship your image!

"All happy cloud deployments are alike; each unhappy cloud deployment is unhappy in its own way." — Leo Tolstoy, Site Reliability Engineer At Gruntwork, I've had the chance to see the cloud adoption journeys of hundreds of companies, from tiny startups to Fortune 50 giants. I've seen those journeys go well. I've seen those journeys go poorly. In this talk, I discuss a few of the ways cloud adoption can go horribly wrong (massive cost overruns, endless death marches, security disasters), and more importantly, how you can get it right. To help you get it right, we looked at the cloud journeys that were successful and extracted from them the patterns they had in common. We distilled all this experience down into something called the Gruntwork Production Framework, which defines five concrete steps you can follow to adopt the cloud at your own company—and hopefully, to end up with your very own happy cloud deployment.

We stress our developers to write tests while they write the code. We set quality gates to avoid releasing code that didn’t pass tests, or doesn’t have enough coverage. But then, when it’s about IaaC, we do exactly the opposite. The time has come for us to discuss the challenges of testing IaaC code, from the necessity of using different languages, to the problems of deploying expensive resources in real world – analyzing the current possibilities and common best practices and looking ahead at the most promising technologies and projects, to boldly go, where no man has gone before: TDD Infra as Code.

While Docker has enabled an unprecedented velocity of software production, it is all too easy to spin out of control. A promotion-based model is required to control and track the flow of Docker images as much as it is required for a traditional software development lifecycle. New tools often introduce new paradigms. We will examine the patterns and the anti-patterns for Docker image management, and what impact the new tools have on the battle-proven paradigms of the software development lifecycle. This talk takes it from the point that everybody already understand the need in the CI/CD pipeline and some of the basic techniques are taken for granted. It’s much more about tools, processes and automation.

Event: Workshop in Agile Summit 2022 (2022-08-31). https://agile.ithome.com.tw/2022/workshop-page/1090 (投影片公開版) ◉ 簡介轉型要成功，需要盡早管理期待。問題是，對敏捷轉型起心動念的人，不見得都能清楚說出對敏捷轉型的期待。事前沒對齊彼此期待，往往會種下半途而廢的惡因。這場工作坊，將以「目標管理」為基礎，帶領大家盤點對於敏捷轉型的期待，並找出敏捷轉型該看的策略性指標。希望這場工作坊，能做為大家推動敏捷轉型的助力。 ◉ 預期收穫 1. 學習以管理者能接受的管理語言，對齊對於敏捷轉型的期待。 2. 以目標管理的方式，規劃敏捷轉型的進程。 3. 根據組織現況及願景，規劃合宜的改革步驟。
