• 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 speaker addresses a question from an audience member regarding the storage of multiple integrated applications in a busy environment
• The speaker explains that open telemetry and Pixie solutions can be used to capture and store data locally, and then filter and batch the data as needed
• The speaker emphasizes the importance of considering sample strategies, filtering, and batching when designing an architecture for managing storage in a busy environment

• GitOps is a set of principles and practices that decouples CI and CD, allowing for a more asynchronous task coordination.
• GitOps tools, such as Flux, Argo, and Carvel, have emerged to support the GitOps workflow.
• Stateful infrastructure is a reality in larger teams and systems, but GitOps can help by providing a desired state for complex computers like Kubernetes.
• The principles of GitOps have driven the development of the tools, resulting in similar workflows across different tool sets.
• The panel emphasizes the importance of understanding what is GitOps material and what is not when setting up infrastructure with tools like Terraform.

• Observability is about understanding applications by looking at metrics, logs, and traces
• OpenTelemetry is a neutral approach to ship telemetry data
• The OpenTelemetry project includes a specification, API, SDK, data model, tools for generating traces, and a collector
• The OpenTelemetry collector can be run on Kubernetes or locally
• The tutorial covers manual and automatic instrumentation
• The OpenTelemetry operator can be used to integrate with Prometheus and get logs from nodes
