Meeting Notes​

IMPROMPTU DEMO: Leveraging the JS ecosystem in Wasm components​

  • Milan Raj from National Instruments gave a demo of example applications using the Hono web framework in Wasm, demonstrating how Wasm components can smoothly utilize JS libraries
  • You can see Milan's examples on GitHub at https://github.com/rajsite/wasm-component-examples
  • You can run the examples in Node or as components
  • Advanced Hono functionality is available
  • Milan also showed off usage of a plugin for bare-bones OIDC management
  • Make sure to check out these excellent examples for yourself!

DEMO: Component instance saturation metrics​

  • There are a number of important questions you'll want to be able to answer when running components in production: How do I know how many instances of a component are running at a given time? How do I know what my max is? How do I know if I need to increase the number?
  • Brooks wanted to use our observability implementation to be able to give definitive answers to these sorts of questions.
  • Brooks demonstrated using Prometheus to query metrics such as active instances.
  • You can also run queries like active instances and max instances as a ratio to represent saturation.
  • This can be used in conjunction with alerting, so if (for example) you meet 80-90% saturation, something is triggered.
  • Brooks recently made a PR to add component_active_instances and component_max_instances metrics. You can find the PR here: https://github.com/wasmCloud/wasmCloud/pull/4398

DISCUSSION: Traits for extending host functionality in embedded cases​

DISCUSSION: Statement on proposed changes to CNCF NATS.io licensing and ownership​

  • The community discussed recent stories on the licensing and ownership of NATS.

  • The wasmCloud project released a statement last week affirming our commitment to open source and the CNCF

  • Brooks shared an architecture diagram outlining the direction for a more fully pluggable wasmCloud

  • We plan to include this diagram in documentation soon

  • Note: On May 1, CNCF and Synadia issued a joint announcement affirming that NATS trademarks will reside with the CNCF and the project licensing will not change. You can see the joint statement here.
