sr.ht, the hacker’s forge, now open for public alpha

Drew Devault, announcing “sir hat” (or however you want to refer to it) For those who are new, let me explain what makes sr.ht special. It provides many of the trimmings you’re used to from sites like GitHub, Gitlab, BitBucket, and so on, including git repository hosting, bug tracking software, CI, wikis, and so on. However, the sr.ht model is different from these projects - where many forges attempt to replicate GitHub’s success with a thinly veiled clone of the GitHub UI and workflow, sr.ht is fundamentally different in its approach. This has folks pretty excited. But what’s all the hubbub about? Well, in addition to being 100% free and open source… sr.ht is special because it’s extremely modular and flexible, designed with interoperability with the rest of the ecosystem in mind. On top of that, sr.ht is one of the most lightweight websites on the internet, with the average page weighing less than 10 KiB, with no tracking and no JavaScript. The flagship product from the software suite is it’s CI platform, which: is easily the most capable continuous integration system available today. It’s so powerful that I’ve been working with multiple Linux distributions on bringing them onboard because it’s the only platform which can scale to the automation needs of an entire Linux distribution. There’s always a potential for hyperbole when the creator is describing their creation, but I’m convinced this is at the very least worth checking out. It might even make for a great episode of The Changelog…

Cloud computing without containers

(READ ALONG IN YOUR FAVORITE MOVIE TRAILER VOICE) … In a world where serverless is still being demystified, CloudFlare, a company who’s focused on pushing things to the edge, launches a game changer for not only serverless, but for cloud computing at large. Unlike every other cloud computing platforms out there, this platform called Workers, doesn’t use containers or virtual machines. This, is the future of serverless and cloud computing. Join Zach Bloom in this epic tale as he tries to convince you why. OK, seriously — this news bubbled up to me enough times that I just had to share it. Here’s the tee up of the problem they faced — how they’re going about solving it is truly a great read. Two years ago we had a problem. We were limited in how many features and options we could build in-house, we needed a way for customers to be able to build for themselves. We set out to find a way to let people write code on our servers deployed around the world (we had a little over a hundred data centers then, 155 as of this writing). Our system needed to run untrusted code securely, with low overhead. We sit in front of ten million sites and process millions and millions of requests per second, it also had to run very very quickly…

Now 2.0

My biggest take away from this epic announcement from ZEIT? The support of the majestic monorepo! …Now 2.0 enables what we will call The Majestic Monorepo, inspired by a similarly named essay by DHH, creator of Ruby on Rails (The Majestic Monolith). We don’t agree that you should be orchestrating a big server abstraction (a monolith), but we believe you should be able to collocate your APIs and your business logic in a single place, with a cohesive deployment story. It looks, feels and deploys like a monolith, with none of its downsides. …but there is SO MUCH MORE to this announcement. Also, we talked a bit about David’s idea of The Majestic Monolith on The Changelog #286.

"GitHub is where source code lives."

I agree — “GitHub is, quite simply, home for developers,” as stated by James Governor in his highlights post on GitHub Universe 2018. Out the gate, James focuses on the announcement of GitHub Actions, which “feels like a profound launch, one that could prove extremely disruptive in the long term.” An idea that seems to have started as “Probot” is now a full fledged and more approachable product offering called GitHub Actions, and looks like it will continue to drive more and developers, developers, developers to GitHub in 2019. Quite simply, Actions could be a disruption driving feature. So what about future implications of Actions for AWS, Microsoft Azure and GCP Cloud compute platforms? Actions could even pose a threat to the centrality and stickiness of the cloud console, because If developers can drive all their workflows from GitHub they have less need to use the console. It might seem absurd to position GitHub as an AWS competitor … but there is no denying the potential for GitHub to lessen the primacy of a cloud operator console in favor of Actions scripted in GitHub, triggering actions and deployments across multiple clouds. GitHub used its keynote to demonstrate the ability to deploy a workload across multiple clouds. Mark your calendars for November 28th! We’re releasing a new episode on The Changelog talking GitHub Actions with Kyle Daigle, Director of Ecosystem Engineering at GitHub, and one of the leaders to bring Actions to fruition. Stay tuned!

Multi-cloud is a trap

This is the battle cry that started the Open Container Initiative. But in reality, are/was multi-cloud and vendor lock-in true concerns for software teams? Tyler Treat writes on his personal blog: We want to be cloud-agnostic. We need to avoid vendor lock-in. We want to be able to shift workloads seamlessly between cloud providers. Let me say it again: multi-cloud is a trap. Outside of appeasing a few major retailers who might not be too keen on stuff running in Amazon data centers, I can think of few reasons why multi-cloud should be a priority for organizations of any scale.

How GitLab CI compares with the three variants of Jenkins

Sid Sijbrandij and the team at GitLab compared GitLab CI with the three Jenkins variants. Here’s what they learned… The many plugin combinations for Jenkins has made Legacy Jenkins hard to configure and brittle when updating. Cloudbees is introducing two new versions of Jenkins to remedy the problem: Cloud Native Jenkins will start from scratch, while Jenkins Evergreen will focus on a set of essential plugins. GitLab CI adds new functionality in the main code base, avoiding the need for needless configuration and ensuring everything still works when updating. Also to note — according to a recent Forrester report GitLab CI and Jenkins/Cloudbees are two of the four leading products for CI.

Cloud native buildpacks

Heroku and Pivotal are working on the next generation of buildpacks and presenting it to the Cloud Native Computing Foundation with the hopes to “greatly improve buildpack interoperability between platforms and attract a wide community of contributors, including buildpack creators and maintainers”. From buildpacks.io: Cloud Native Buildpacks are a new effort initiated by Pivotal and Heroku in January 2018. Cloud Native Buildpacks aim to unify the buildpack ecosystems with a platform-to-buildpack contract that is well-defined and that incorporates learnings from maintaining production-grade buildpacks for years at both Pivotal and Heroku, the largest contributors to the buildpack ecosystem. Buildpacks are pluggable, modular tools that translate source code into container-ready artifacts such as OCI images. They replace Dockerfiles in the app development lifecycle with a higher level of abstraction. The proposal offers buildpacks as replacement to Dockerfiles, while serving as a higher level of abstraction. The presentation is tonight (Aug 21) @ 8pm PDT and details on joining the meeting are in the CNCF TOC readme.

Kubernetes' CPU Manager

Feature highlights of the beta CPU Manager in Kubernetes from Balaji Subramaniam, Cloud Software Engineer and Connor Doyle, Cloud Software Architect at Intel AI… A single compute node in a Kubernetes cluster can run many pods and some of these pods could be running CPU-intensive workloads. In such a scenario, the pods might contend for the CPU resources available in that compute node. When this contention intensifies, the workload can move to different CPUs depending on whether the pod is throttled and the availability of CPUs at scheduling time. There might also be cases where the workload could be sensitive to context switches. In all the above scenarios, the performance of the workload might be affected. If your workload is sensitive to such scenarios, then CPU Manager can be enabled to provide better performance isolation by allocating exclusive CPUs for your workload.

Will Kubernetes collapse under the weight of its complexity?

Paul Dix, Founder and CTO of InfluxData, writes on the InfluxData blog: I attended and spoke at KubeCon EU. It was a massive event attended by around 4,700 people … However, I felt there was an underlying problem … everyone I spoke with was either an operator or an SRE. Where were all the application developers? Aren’t those the people that all this complex infrastructure is supposed to serve? Which raised questions for Paul, like… Is Kubernetes too complex? Will it end up collapsing under the weight of its own complexity? Will it fade away as OpenStack has seemed to since 2014? And Paul walked away from KubeCon EU with this perspective: Application developers would be better served by having a happy path to follow with the tools preselected … CNCF’s increasing complexity and broader reach might dilute the focus and brand of Kubernetes … I’m not sure what the answer might be to this or if I’m overblowing it, but from my perspective at the conference, it was like tool porn. Why bother with solving user problems when you can spend your entire career learning about and building new tools for infrastructure?

Open sourcing Zuul 2

Netflix open sourced their cloud gateway: The Cloud Gateway team at Netflix runs and operates more than 80 clusters of Zuul 2, sending traffic to about 100 (and growing) backend service clusters which amounts to more than 1 million requests per second. Pretty impressive. Click through to get the details of how Zuul 2 works and how they use it inside Netflix. I love when companies who are operating at webscale (😏) share their practices and code with the rest of us.

Red Hat to acquire CoreOS

This is a big deal. We’ve been tracking CoreOS since the beginning — we’re huge fans of Alex, Brandon and the team behind CoreOS. Red Hat has signed a definitive agreement to acquire CoreOS, Inc., an innovator and leader in Kubernetes and container-native solutions, for a purchase price of $250 million. Red Hat is a publicly traded company and while this announcement hasn’t really impacted shareholder value (yet), we, the open source community have been immeasurably impacted by the team behind CoreOS. Also, check out Alex Polvi’s announcement on the CoreOS blog which includes some details and backstory.
