A behind-the-scenes look at how our small systems engineering team manages our infrastructure. This is centered around MySQL and MongoDB.
We'll go through real-world implementation with code examples, showing how we:
- Built a flexible automation framework that adapts to new technologies
- Created a sustainable way for a small team to manage enterprise-scale infrastructure
- Turned "those #@$% servers" into well-behaved, predictable systems
Ceph is an open source distributed object store, network block device, and file system designed for reliability, performance, and scalability. It runs on commodity hardware, has no single point of failure, and is supported in the Linux kernel.
This tutorial will describe the Ceph architecture, share its design principles, and discuss how it can be part of a cost-effective, reliable cloud stack.
Explore the evolving integration of CephFS with OpenStack Manila in this session, where we’ll delve into the unique features CephFS brings to cloud file systems. We’ll cover the trade-offs of CephFS Native and CephFS NFS, highlighting practical reasons why each might not fit all use cases. Wrapping up, we’ll look at future innovations, like the SMB driver and VirtIOFS, that promise to expand functionality and use cases for OpenStack file sharing. Join us for a deep dive into these powerful tools and their future in cloud architecture.
In this talk, you will learn how to use Sunbeam – a cloud-native OpenStack powered by Kubernetes – and Charmed HPC to streamline the deployment and management of modern HPC clusters. You will learn how to use Sunbeam to set up OpenStack, and how to dpeloy Charmed HPC on top of OpenStack. Lastly, you will learn how to set up Kubernetes next to your HPC system to provide services such as identity management and observability metrics.
Setting up a modern HPC system does not need to be a dark and stormy process - it can be as clear as day with Sunbeam!
Pip, Conda, Poetry, and now, the Rust-based Uv. Python is a complex ecosystem fraught with pitfalls, fragmentation & historic legacy. Nix provides a unifying way to deal with complex software environments. However, language integration tooling for Python has been lacking. In this talk we'll explore pyproject.nix & uv2nix to wrangle everything from simple projects using requirements.txt & pyproject.toml to complex applications and monorepos.
The adoption of open source software is on the rise across all industries, but what 'open source' means (even if they use the right licenses) is getting muddier and muddier. It can be hard to know for sure whether your efforts will benefit a corporation, a community, or both.
In this talk you will get a crash course on open source licensing, the differences and similarities in open source projects depending on who's funding it, the different ways you can engage with the types of projects, and how to decide what type of project you want to work on.
This talk will focus on the development of an open-source Earth System Model (ESM) by the Climate Modeling Alliance (CliMA), which aims to address the limitations of existing, outdated ESMs that are computationally expensive and not readily publicly accessible. CliMA's model is being built from scratch to be less resource-intensive while maintaining scientific accuracy, making it more useful to the broader scientific community. The talk will highlight the benefits of providing such a model as open source to support climate research and collaboration.
Many organizations have adopted the cloud for software deployment but still rely on local machines for development. A Cloud Development Environment (CDE) is now essential. This talk explores deploying a secure, scalable CDE that enhances performance and developer experience. Key focus areas include automation, self-service, efficiency, and fostering collaboration. Attendees will learn how to leverage cloud-native technologies, justify costs, and ensure long-term innovation, reducing time-to-market and boosting competitiveness.
Learn how cloud-native technologies like Kubernetes are revolutionizing database software, enabling scalability, resilience, and agility. Join Divine, a Data on Kubernetes Ambassador to explore real-world examples and best practices for building the next generation of database solutions.
At Walmart, Openstack clouds host large-scale applications with varying characteristics. We developed an algorithm to efficiently distribute and place workloads, preventing hotspots and performance degradation caused by noisy neighbors. The Cloud Rebalance strategy is designed to complement Openstack’s Live Migration feature, enhancing workload placement.
