Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Data Streaming Architecture
The structure of this example message is using CloudEvents specification:

Show HN: Automatisch – open-source workflow automation, an alternative to Zapier
CloudEvents is trying to standardize on the messaging

A message queue focus on serverless program
Hello guys, actually, vanus can directly deliver messages to OpenFaaS without this kind of connector. Because vanus can deliver messages that follow the CloudEvents standard, OpenFaaS can also receive such messages. More details https://docs.linkall.com/how-to/use-gcloud-functions

An alternative look at workflows in cloud era
Lastly, workflow as a function flow in Automatiko is also based on Funqy, but this time it leverages Knative project to build function chaining based on events (Cloud Events). Knative is a kubernetes based platform to deploy and manage modern serverless workloads. In particular, Knative eventing comes with universal subscription, delivery and management of events that allows to build modern applications by attaching business logic on top of the data stream - the events.

Google Cloud Functions 2nd gen
One of the most exciting 2nd gen functionality is the ability to create functions of Cloud Events type. These are event functions that, instead of receiving an event in a proprietary Google Cloud format, will receive one in a standard format as described in the Cloud Events specification.

GraphQL for Event Driven Architecture
Curious why you decided to go for GraphQL instead of something like Cloud Events spec (https://cloudevents.io)
-
What's your experience with event driven?
There is also https://cloudevents.io but I have never used it.

Getting Started with CloudEvents and AsyncAPI
There are a few extensions worth mentioning, one of them is for distributed tracing. However, it seems there is some discussion around removing this extension from the spec (check this PR on GitHub). There are open issues on some SDKs to support it, and others have already made changes to remove it. The future isn't clear, but I'd argue it's interesting to follow this closely for any updates, since tracing events is very important in an event-driven architecture.

KubeCon North America 2022: A Retrospective
One of the other places I spent a lot of time at at KubeCon NA was the CNCF Project Pavillion. I was very happy to see that it was a bit larger than the area we had during KubeCon EU, but I still wish that it was bigger and wasn’t so tucked away in the corner. A number of booths were showcasing their projects with demos through the week, hosted Q&A time, and gave away swag. If you are still trying to understand the Cloud Native Ecosystem, you can look at this very extensive map of the landscape and projects under the CNCF, some of which are more advanced than others. Of course I’m biased, but I’m really excited for the work that Keptn is doing in helping developers have more control over their application lifecycle. I’m also very excited to see where Backstage goes and how other CNCF projects can integrate with their service catalog.

Part-2: Evaluating Application Resiliency with Keptn and LitmusChaos (use-case and demo)
Go try this out and share your feedback on what you like about this integration and what you’d like improved. Feel free to create issues, engage in discussions on the Keptn Slack and Litmus Github repository. Stay tuned for more updates on how you can leverage Keptn & LitmusChaos CNCF projects to build and ship resilient cloud-native applications!
Jmeter: Jmeter is used to generate load on the helloservice app based on a predefined config (in this case, a performance profile), to simulate real-world traffic. As mentioned earlier, Keptn allows for the execution of parallel tasks by triggering multiple tools simultaneously via its event-driven approach and dedicated control plane services. The tool is invoked via the Jmeter Service. The intent here is to simulate real-world traffic to set the app under stress and simulate standard conditions for SLO evaluation and relative benchmarking.
