Zan Markan Developer Advocate @ CircleCi What's the longest CI/CD build you worked with? Mine once took whole day. This is a tale of creating and taming that monster build. When developing software and maintaining CI/CD and testing pipelines we are often compelled to increase our test coverage by adding more tests, and therefore improve our apps’ quality. After all, more automation equals better software, right? There’s a flipside to this equation however, and a point at which we start seeing diminishing returns from each test we add. Taken to extreme, these diminishing returns begin to actively harm our ability to deliver working software. In this talk we will look at a tale of creating and taming a monster of an all day build (one that really happened to me once), and cover tips, tricks, and tools to help you avoid that scenario in the future - from obvious suggestions such a s adding resources to your build machines, to less obvious ones like removing tests altogether. This talk will cover tips, tricks, and tools that help you speed up builds - from adding resources to test splitting to bringing a hatchet to your test suite. — 00:00 Intro 00:40 Talk — 🥇 Gold Sponsors: Chaos Native Fugue Honeycomb.io StackPulse Teleport 🥈 Silver Sponsors: 7bulls.com Aerospike Alwaysdata Aspecto bxblue Capgemini CircleCi Container Solutions CloudSkiff Earthly Hazelcast Imply Lightrun Logz.io Lumigo MongoDB Nuaware Qwinix Zeti 🤝 Media Partners: Manning AWS Inside Dev — Website 🚀🪐 https://www.conf42.com​ Reach Out 📧📭 mark@conf42.com Discord Server 🧑‍🤝‍🧑💬 https://discord.com/invite/dT6ZsFJ5ZM​ LinkedIn 👨‍💼💼 https://www.linkedin.com/company/4911...​ Twitter 🎵🐦https://twitter.com/conf42com​ Conf42Cast 🎧 http://www.conf42.com/podcast

Lian Li Engineering Manager @ Container Solutions Kubernetes has become the new darling of the infrastructure world. Not only is it a great piece of technology for managing your containers, but in conjunction with the possibility to rent managed clusters from any of the big Cloud providers, Kubernetes offers organisations the possibility to get rid of the shackles of hosting and/or managing one’s infrastructure. But that does not mean that Kubernetes is a one-size-fits-all solution. Especially in big corporations, bigger, systemic and/or more pressing problems could be revealed while implementing a big shift like moving to the cloud. As consultants, we can often observe the chaos and frustration that breaks out, when the vision of management does not align with the reality of what the teams are able to deliver. More often than not, it’s not a technological problem, but a cultural one. When is an organisation ripe for cloud transformation? How can we make sure we are addressing the problems at their root? Kubernetes alone won’t save you, but with the right mindset, it might be just what you needed to save yourself. — 00:00 Intro 00:40 Lian Li 01:33 Kubernetes won't save you 02:14 The state of Kubernetes 04:42 You're holding it wrong 05:03 What is Cloud Native? 11:49 Form follows function 13:02 The Golden Circle 15:45 Continuous Learning 17:33 Psychological safety 20:58 Collaboration 21:25 3 core interaction modes 24:56 Cloud Native Transformation Kit 26:03 Thank you! — 🥇 Gold Sponsors: Chaos Native Fugue Honeycomb.io StackPulse Teleport 🥈 Silver Sponsors: 7bulls.com Aerospike Alwaysdata Aspecto bxblue Capgemini CircleCi Container Solutions CloudSkiff Earthly Hazelcast Imply Lightrun Logz.io Lumigo MongoDB Nuaware Qwinix Zeti 🤝 Media Partners: AWS Inside Dev Manning — Website 🚀🪐 https://www.conf42.com​ Reach Out 📧📭 mark@conf42.com Discord Server 🧑‍🤝‍🧑💬 https://discord.com/invite/dT6ZsFJ5ZM​ LinkedIn 👨‍💼💼 https://www.linkedin.com/company/4911...​ Twitter 🎵🐦https://twitter.com/conf42com​ Conf42Cast 🎧 http://www.conf42.com/podcast

Dhiraj Hegde Architect @ Salesforce Operating a distributed system like HBase/Hadoop FS at peta byte scale took years to master in our private data centers. This talk describes our dramatic shift towards running a mission critical stateful application on Kubernetes in Public Cloud, why we did it and the challenges we had to overcome. Salesforce runs a very large footprint of HBase and HDFS clusters in our data centers with multiple petabytes of data, billions of queries per day over thousands of machines. After more than a decade of running our own data centers, we pivoted towards public cloud for its scalability and availability. As part of this foray, we made a bold decision to move our HBase clusters from staid bare metal hosts to the dynamic and immutable world of containers and Kubernetes. This move brought with it a number of challenges which are likely to find echoes in other such mature stateful applications adapting to public cloud and Kubernetes. The challenges include 1. Limitations in Kubernetes while deploying large scale stateful applications 2. Failures in HBase/HDFS as the DNS records keep changing in Kubernetes 3. Resilience of HBase/HDFS even when a whole availability zone fails in Public Cloud 4. Introducing encryption in communication over untrusted public cloud networks without application being aware This talk will go over how we overcame these challenges and the benefits we are beginning to see from these efforts. — 00:00 Intro 00:40 Talk — 🥇 Gold Sponsors: Chaos Native Fugue Honeycomb.io StackPulse Teleport 🥈 Silver Sponsors: 7bulls.com Aerospike Alwaysdata Aspecto bxblue Capgemini CircleCi Container Solutions CloudSkiff Earthly Hazelcast Imply Lightrun Logz.io Lumigo MongoDB Nuaware Qwinix Zeti 🤝 Media Partners: Manning AWS Inside Dev — Website 🚀🪐 https://www.conf42.com​ Reach Out 📧📭 mark@conf42.com Discord Server 🧑‍🤝‍🧑💬 https://discord.com/invite/dT6ZsFJ5ZM​ LinkedIn 👨‍💼💼 https://www.linkedin.com/company/4911...​ Twitter 🎵🐦https://twitter.com/conf42com​ Conf42Cast 🎧 http://www.conf42.com/podcast

Shelby Spees Developer Advocate @ Honeycomb.io How did Honeycomb have the confidence to migrate to a more efficient processor architecture, resulting in a 40% reduction in AWS spend on their backend ingest service? In this talk, Shelby Spees explores how Honeycomb’s platform engineering measured the risk and ROI of moving their high-traffic ingest workloads to the new ARM-based Graviton2 processor architecture. Learn how high-cardinality observability data supported performing side-by-side comparisons of the same workloads on different processor architectures, and how to gain similar insights into your own infrastructure. — 00:00 Intro 00:40 Talk — 🥇 Gold Sponsors: Chaos Native Fugue Honeycomb.io StackPulse Teleport 🥈 Silver Sponsors: 7bulls.com Aerospike Alwaysdata Aspecto bxblue Capgemini CircleCi Container Solutions CloudSkiff Earthly Hazelcast Imply Lightrun Logz.io Lumigo MongoDB Nuaware Qwinix Zeti 🤝 Media Partners: Manning AWS Inside Dev — Website 🚀🪐 https://www.conf42.com​ Reach Out 📧📭 mark@conf42.com Discord Server 🧑‍🤝‍🧑💬 https://discord.com/invite/dT6ZsFJ5ZM​ LinkedIn 👨‍💼💼 https://www.linkedin.com/company/4911...​ Twitter 🎵🐦https://twitter.com/conf42com​ Conf42Cast 🎧 http://www.conf42.com/podcast

Stephane Jourdan CTO @ CloudSkiff As infrastructure as code (IaC) becomes widely adopted by users with heterogenous skillsets, and as IaC codebases become larger and larger, it becomes harder to track drift. Drift is a deviation between the actual infrastructure state and the IaC codebase. It causes issues for security posture management, collaborative work, and maintenance. It’s hard to improve what you can’t measure! Can we define good metrics for drift? Developers track unit tests coverage to track how well unit tests match application code over time. Can we use an analogy and define infrastructure code coverage to track how well IaC matches the actual infrastructure state? In this talk, we will show how minor infrastructure drift can cause issues. We will then introduce various ways to track IaC coverage, and how we can use them to bring visibility into the state of infrastructure and anticipate common drift issues. We will also show how measuring IaC codebase also benefits IaC adoption. — 00:00 Intro 00:40 Talk — 🥇 Gold Sponsors: Chaos Native Fugue Honeycomb.io StackPulse Teleport 🥈 Silver Sponsors: 7bulls.com Aerospike Alwaysdata Aspecto bxblue Capgemini CircleCi Container Solutions CloudSkiff Earthly Hazelcast Imply Lightrun Logz.io Lumigo MongoDB Nuaware Qwinix Zeti 🤝 Media Partners: Manning AWS Inside Dev — Website 🚀🪐 https://www.conf42.com​ Reach Out 📧📭 mark@conf42.com Discord Server 🧑‍🤝‍🧑💬 https://discord.com/invite/dT6ZsFJ5ZM​ LinkedIn 👨‍💼💼 https://www.linkedin.com/company/4911...​ Twitter 🎵🐦https://twitter.com/conf42com​ Conf42Cast 🎧 http://www.conf42.com/podcast
