AWS is committed to supporting open source and Kubernetes, and has made significant investments in sustainability and community engagement. They have observed that choice, security, and flexibility are key factors for Kubernetes users.
  • AWS invests in open source sustainability through bug fixes, code reviews, and major financial and organizational initiatives
  • AWS has contributed $10 million to the Open Source Security Foundation, committed their entire patent portfolio to the Open Innovation Network, and pledged $3 million in Cloud credits and engineering resources to the CNCF
  • Choice is a major factor for Kubernetes users, but can also create undifferentiated heavy lifting. Users who take the time to consider their options and assume responsibility for their use cases have the most success
  • Kubernetes security is critical but not guaranteed. Best practices and controls must be configured, and there are opportunities to build and enhance security tools using emerging technologies like AI and global data sources
  • Kubernetes offers flexibility to create secure environments, but this requires knowledge, planning, and constant effort
  • Kubernetes has roots in microservices but has expanded to nearly every type of application, and users are running data processing pipelines, transaction management systems, game servers, and AI inference on the platform

The presentation discusses the functionalities and components of the Amway ecosystem and how to make it production-ready.
  • The Amway ecosystem has various components such as circuit breaker, cluster and endpoint discovery, and even streamer.
  • Capacity management, performance, scalability, security, and operational readiness are important factors to consider in making the Amway system production-ready.
  • The Apprentice public roadmap is available on GitHub for customers to provide feedback and suggestions.
  • The presentation emphasizes the importance of observability, reliability, and availability in building a solid request relative with high throughput and performance.

The presentation discusses the three-phase migration process for moving from a non-HA control plane to an HA control plane in Kubernetes, with a focus on protecting the cluster state and ensuring minimal impact on workloads.
  • The migration process is divided into three phases, with multiple steps in each phase to ensure the cluster state is protected and workloads are not impacted
  • The first phase involves getting the cluster state from the non-HA control plane and building a snapshot for use in the second phase
  • The second phase involves migrating the cluster state to the HA control plane, with traffic to the control plane shut down to prevent class data mutation
  • The third phase involves confirming that everything is working properly and reopening traffic to the control plane
  • The main focus throughout the migration process is on protecting the cluster state and ensuring minimal impact on workloads

Well-maintained applications have thorough unit tests, integration tests and performance tests. Despite this coverage, production incidents still occur due to infrastructure failures, network faults, or unexpected traffic patterns. These failures cannot be covered with traditional test suites. In this session, we will share how we adopted the open source Chaos Toolkit to test the resilience of an application on AWS.  We will discuss design decisions on entitlements, project structure, and cloud architecture that we consider when building out a chaos test suite.

kOps has been adding support for IPv6 clusters. Learn about the design of and challenges faced in providing a turnkey IPv6 Kubernetes infrastructure, including on AWS and other clouds. kOps maintainers will describe the use cases they are targeting, the network architecture they chose, and how they are managing address allocation. They will give details on the components, both internal and in upstream projects, that needed changes to support IPv6 and the bugs and limitations they had to work around. They will also reveal trivia, such as why the kOps service network is fd00:5e4f:ce::/108.Click here to view captioning/translation in the MeetingPlay platform!

The presentation discusses the use of Kubernetes to manage Mac compute shapes on AWS for iOS builds, with a focus on Flare.build's experience and lessons learned.
  • Flare.build is part of Google's Bazel Experts Program and offers value-added services for building and testing applications at scale using Bazel
  • Nodeless Kubernetes, developed by Ilota, aims to provide compute that comes up and disappears according to application lifecycle, and can be used to manage Mac compute shapes on AWS
  • The presentation discusses the challenges of unifying different compute types for distributed builds, and the benefits of using Kubernetes to manage Mac compute shapes on AWS
  • The presenters share their experience evaluating manually-managed vs Kubernetes-managed Mac compute shapes on AWS, and suggest best practices for managing Mac compute shapes on Kubernetes

Workday is shifting to a multi-cloud approach whereby its Kubernetes platform known as Scylla can be deployed to public cloud providers as well as Workday’s own data centers. To achieve this, we needed to route tenant data across existing AWS clusters in different regions, to Workday’s own data centre, and potentially in the future, to other public cloud providers. While cloud providers usually have solutions to migrate data to their own cloud, Workday aims to be cloud-agnostic, and as such needs a solution to migrate data cross-clouds. The infrastructure, platform, and application development teams cooperated to develop a solution relying on Kubernetes operators, Istio, Consul, and Helm-delivered application configuration. This talk will give an overview of the tools and technologies used to migrate tenant data to other clusters, wherever they are deployed. We will additionally review the learnings from this experience and give an overview of the future work.
