> Oracle, SUSE, and Rocky Linux are all taking aggressive stances against Red Hat's new rules for using Red Hat Enterprise Linux open-source code. AlmaLinux, however, is taking a more amicable approach.
> I imagine I am not the only systems administrator who struggled with driving security compliance across a disparate fleet of Linux systems. It took up hours of administrative time and often required interaction with a third-party auditor to validate the results. Let’s talk about the multiplication here: You may have a batch of systems that handle payment processing, so they are required to comply with the rules for PCI-DSS. You may have another set of systems that handle your patient’s medical records, which would fall under the purview of HIPAA.
> At Red Hat Summit 2023, the engineering team announced two projects that will change the way developers and ops develop and deploy their applications to Red Hat OpenShift. These projects are the Red Hat Trusted Application Pipeline and the Red Hat Developer Hub. They are a little different from the usual Red Hat products in that they directly address critical composite problems in the DevSecOps space that customers are starting to experience issues.
> Red Hat has long been acknowledged as the provider of enterprise strength frameworks and platforms, notably Red Hat Enterprise Linux and OpenShift, the enterprise distribution of Kubernetes. Both are incredibly powerful product sets, but to get the most out of them, we have to understand and use them as experts would. Most developers and ops personnel don’t have the time, on top of their day-to-day jobs, to learn every aspect of the underlying technology. The likely result of this missing knowledge is the eventuality of various security issues.
> Custom server tasks can be deployed to the Red Hat Data Grid server for remote execution from the command line interface (CLI) and Hot Rod or REST clients. Tasks can be implemented as custom Java classes or as scripts in languages such as JavaScript.
> In this article, we will deploy a Java class that will evict and reload the cache in order to pick up modified entries in the original database table from which we loaded the cache. Data Grid will automatically load new entries added to the database table, however modified rows will require reloading using a server task, as shown in the following example.
