Don't forget to uv self update before trying those

Hola,
Recently, I have made several changes to the AsBuiltReport.Veeam.VBR script, so I will summarize here all the new capabilities added.
Here is the link to the most recent report in HTML format: Report The first change I will discuss is the support for Microsoft Entra ID. In this case the Veeam Backup & Replication (VBR) Powershell module allows extracting the information of the Tenants that are configured in the VBR infrastructure.

Deploying modern web apps – with all the provisions needed to be fast and secure while easily updateable – has become so hard that many developers don’t dare do it without a PaaS (platform-as-a-service). But that’s ridiculous. Nobody should have to pay orders of magnitude more for basic computing just to make deployment friendly and usable. That’s a job for open source, and Rails 8 is ready to solve it. So it’s with great pleasure that we are now ready with the final version of Rails 8.0, after a successful beta release and several release candidates!

Let's walk through a common scenario.

Kubernetes doesn't load balance long-lived connections, and some Pods might receive more requests than others. If you're using HTTP/2, gRPC, RSockets, AMQP or any other long-lived connection such as a database connection, you might want to consider client-side load balancing.

Automation is an increasingly interesting topic in pretty much every technology discipline these days. There’s lots of talk about tooling, practices, skill set evolution, and more - but little conversation about fundamentals. What little is published by those actually practicing automation, usually takes the form of source code or technical whitepapers. While these are obviously valuable, they don’t usually cover some of the fundamental basics that could prove useful to the reader who wishes to perform similar things in their own organization, but may have different technical requirements.

A short while back I participated in an internal event. A number of priority customers of our internal cloud service were invited for a feedback session, to voice their thoughts, listen to roadmap sessions and just to get to know each other.
