OpenWhisk VS hub-feedback

Serverless functions are now offered by many cloud providers, as well as having options like OpenFaaS, Knative, Apache's Openwhisk and more from the open source community that run in environments ranging from one server all the way up to globally replicated private clusters.

OpenWhisk - https://openwhisk.apache.org

The serverless functions with Digital Ocean are based on Apache Open Whisk, so the service has additional name space, which need to go into the URL.

The two biggest options are OpenWhisk and OpenFaas. Check out /r/serverless for more options. I'm experimenting currently with OpenFaas as it's the lighter weigh to of the two.

If you meant lambda for cloud functions provided by Amazon then this is open source and free, as long as you host it yourself: https://openwhisk.apache.org/

There are so many of them in big data, e.g. Kafka, Spark, Flink, Delta, Snowplow, Finagle, Deequ, CMAK, OpenWhisk, Snowflake, TheHive, TVM-VTA, etc.

The foundation is Apache OpenWhisk https://github.com/apache/openwhisk with DO specific customization to work with managed databased, log shipping, and other DO specific capabilities. The closest programming model is AWS Lambda in terms of the semantics and execution model.

image: this key specifies the image this container is based on to be created. It can be a local image or an image from the Docker hub.

Finally, we can upload our application to Docker Hub so that other people can use the image we created. To do this, follow the steps below:

Pull the official Docker distribution of pgAdmin 4 from the Docker Hub repository with the following command:

To use Docker Scout, you'll first have to have a Docker Hub account. Follow the installation instructions for Docker Scout on GitHub. Once Docker Scout is installed, you can sign in to Docker Hub on the command line with the docker login command.

Go to Docker Hub, sign up, and log in to your account's overview page.

There are a lot of docker-compatible registries almost every cloud provider has its registry but for this article, we will use the docker registry called docker hub. Go to the website create a new account and sign in then you can push or pull images.
