Hello Adam,

Thank you for running these informative sessions every month!

In the last airhacks session there were valid questions by @hrstoyanov on authentication and you mentioned about Keycloak. He has some valid concerns and I just wanted to share https://gluu.org/ suites better. Have you had a look at it? I know you would rather implement your own server but it gets a bit complicated with FIDO and stuff and becomes time consuming especially on short projects.

Thanks,
Vaibhav

Thanks for pointing me to gluu.org. it sounds as ambitious as www ory.sh, but it is not free.

I ended up using AWS cognito for my project

Hi Adam,

We are in a situation where we plan to develop multiple Jakarta EE 8 monoliths communicating with JAX-RS call to retrieve data from each other. We are thinking of using Payara Server with the integrated Hazelcast DataGrid to cluster each moniolith and to benefit from the cache,

1. What is your experience with such technologies ?
2. Is it reliable in a situation with this kind of architecture knowing that we dont have enough resources to do microservices ?

Thanks

Hi Adam,

• is there a way to create new managed executor services programmatically in Glassfish/Payara? or is domain.xml the only place where it is possible?
• Is it a good practice to have several managed executor services or should the default one be enough for all the application purposes?

Hi Adam,
In today's software development process, how much GOF design pattern play a role?

Hi Adam,

How should we think in cloud native environments compared to native local development where we code our monolith on local environment against a local application server and when we finish the feature / product push the code to production app servers like tomcat.

Can you present some developer workflow for cloud native environments for example with AWS Services ?

• Lambda
• API Gateway
• Local / Remote Debugging which makes sense, whats changes compared to without a cloud native env?
• CI/CD
• Fargate

Thank your very much

I have two payara servers but not running in an payara cluster. A loadbalancer distributes load over the two servers. I'm using eclipselink and I want to use eclipselink cache coordination and preferably hazelcast to handle the cache invalidation on the other server(s). Is this possible without using a payara cluster (with DAS) ? I tried but no success.

Second question: Can I use hazelcast for eclipselink cache coordination when running microprofile instead of a full payara server?
