• KubeVela is an application-centric control plan that connects with traditional CI systems or modern Github and provides best practices for platform engineering.
• The Open Application Model provides a consistent model for application delivery and infrastructure-agnostic model that allows developers to focus on components trades and deploy to different runtime platforms.
• KubeVela balances extensibility and user experience by leveraging the Kubernetes API and CRD ecosystem, providing API systems, SDKs, and a UI console.
• KubeVela provides powerful orchestration by allowing data passing for application components dependency, overriding parameters for multi-environments delivery, defining rollout and traffic splitting ways, and checking metrics with quality gates to ensure safe delivery.
• KubeVela manages resource management by sharing resources in multiple applications, defining the replicas of application at initialization while working with an HPA later, and defining different garbage collection policies for data storage and workload metadata.
• KubeVela ensures large scale and stability by horizontally scaling the controller, improving performance for different scenarios, and providing a catalog of add-ons that can connect to the whole community.

• The system was designed with the goal of making it easy for developers to get started and ensuring commonly needed changes would be simple to make
• The system includes a config CLI and API, a version schema, and a customization system
• The config CLI provides a familiar interactive workflow for developers to modify production configuration
• The config API simplifies the user experience by explicitly encoding the main application properties that developers need to control
• The version schema allows for formal versioning and evolution of the system over time
• The customization system allows for advanced users to leverage the full power of Kubernetes APIs when needed
• The system strikes a balance between exposing changes and ensuring meaningful review, while also accommodating the needs of a wide range of users

• Capacity planning requires up-to-date and fresh data, and aggregation at collection time to reduce scope.
• The project provides a tool for capacity planning that does not require knowledge of prompt URL.
• The metrics framework provides stability levels to prevent breaking changes and automation to prevent users from making breaking changes.
• Structured logging in JSON format is easier to query and analyze than text-based logging.
• Contextual logging allows for attaching context and data to log lines for better analysis and correlation with tracing.
• The structured logging working group is actively working on migrating the code base to structured and contextual logging.

• The example architecture includes an external facing service using TLS, mutual TLS for service communication, and web identity federation for accessing AWS services
• Two approaches are presented: a simple web service and a service mesh approach using Istio and OPA
• Data flow diagrams are essential for threat modeling and can be used to apply STRIDE to individual communications
• Prototyping early helps to understand technology integration and potential issues
• The presentation includes a relevant anecdote about a last-minute issue with AWS policies on S3 buckets

• GraphQL is a query language and server-side runtime that provides a monolithic facade on top of complex microservice architecture
• Using GraphQL introduces new challenges when isolating failures and troubleshooting performance issues
• OpenTelemetry can help monitor and improve troubleshooting for GraphQL queries in production
• The RED method can be used to monitor the health and performance of distributed systems
• Instrumenting GraphQL services with OpenTelemetry can provide distributed traces for monitoring

• UDP proxies can make game servers harder to take down and provide more redundancy
• Open source standard tooling can be established for this kind of work
• The iguana's XDS provider can manipulate all the rest of the proxies
• Active communities exist for game servers, game server orchestration, and extending Kubernetes in weird and wonderful ways
