How not to start with Kubernetes – Lessons learned from DevOps Engineer Christian Heckelmann
To k8s or not – that should be the first question to answer before considering k8s. Granted – in many cases k8s is going to be the right choice but don’t just default to k8s because its hip or cool.In this episode we have Christian Heckelmann (@wurstsalat), DevOps Engineer at ERT, talking about his journey with k8s which started with installing k8s 1.9 on bare metal. He gives a lot of great advice based on his presentation “How not to start with k8s” such as Understand Networking, Don’t use :latest, Set Resource Limits, Train The People, Provide Templates and more.To get started with Kubernetes we encourage you to look at the YouTube Tutorials posted on TechWorld with Nana.https://twitter.com/wurstsalathttps://docs.google.com/presentation/d/1EL9OYe-1eOPXh6U8SMHnQxs8pcmr01d-uwoWoFnzUaY/edit#slide=id.g5420f4ebeb_0_5https://www.youtube.com/channel/UCdngmbVKX1Tgre699-XLlUA

How to protect continuous software delivery against supply chain attacks with Michael Plank
Software security is about securing websites against malicious attacks or using firewalls to prevent hackers entering your enterprise network. While this is part of software security there is much more that needs to be done – especially as more organizations are developing critical software it is important to protect the whole software delivery lifecycle from any malicious attacks along the supply chain.In this episode we have Michael Plank, Technical Product Manager at Dynatrace, talk about his latest blog post titled How Dynatrace protects its software development and delivery life cycle against supply chain attacks. We learn about attack vectors from development workstation until production deployment. He covers the strategies ranging from static to dynamic code analysis, vulnerability detection or code signatures. Tune in and learn that building secure software is more than ensuring your users have hard to crack passwords!https://www.dynatrace.com/news/blog/how-dynatrace-protects-its-software-development-and-delivery-life-cycle-against-supply-chain-attacks/

What is Data-Driven Continuous Delivery aka CDv2 with Tracy Ragan
When moving to microservice architectures its time to re-think continuous delivery. Just as many software services rely on a core data analytics engine to make better automated decisions we need to apply the same for continuous delivery. We can assess the risk of every microservice deployment based on data from production and the desired change of configuration. We can assess the potential blast radius and mitigate it through modern delivery options such as blue/green, canaries or feature flags.Tracy Ragan, Creator & CEO of DeployHub, CDF board member and DevOps Institute Ambassador shares her thoughts on why we need to move to smarter data-driven delivery pipelines. Tracy (@TracyRagan) gives us insights into why not every microservice is created equal and what approaches we can take to better control updates that contain multiple microservice updates.Also make sure to check out their latest project Ortelius and take Tracy up on a virtual coffee chat as discussed in our podcast!https://www.linkedin.com/in/tracy-ragan-oms/https://twitter.com/TracyRaganhttps://github.com/orteliushttps://go.oncehub.com/15-30MinuteVirtualCoffeeWithTracy

How to successfully run k8s software in SaaS and on-premise with Marc Campbell
K8s enables organizations to more easily deploy their containerized solutions as it takes away a lot of the operational tasks which are built-into k8s. This in theory means that you can run your software anywhere and provide it as SaaS offering or deploy it behind corporate firewalls for those customers that demand an on-premise installation.In this episode we have Marc Campbell, Founder and CTO of Replicated, where they help the k8s community to deliver and manage apps on k8s anywhere. For anyone looking into running their apps on k8s you will learn the challenges of Day 1 (delivery, install) and Day 2 (operation, monitoring, troubleshooting) operations. Marc shares common performance and scalability challenges and how to prepare for them during development.In this episode we have Marc Campbell, Founder and CTO of Replicated, where they help the k8s community to deliver and manage apps on k8s anywhere.
