Red Hat Enterprise Linux for SAP with HA and Update Services 9.0

I use Red Hat Enterprise Linux (RHEL) for servers as well as workstations.

We have around 3,000 workstations that our developers are working on using Citrix remote access. For servers, we are using it for typical web server, database hosting, as well as containerized workloads.

The challenge with our use cases in Red Hat Enterprise Linux (RHEL) is that we're completely disconnected from the internet. We have a satellite server which is also connected to the internet, which syncs to a disconnected satellite as well.

We use Red Hat Satellite for provisioning machines and we use Ansible for configuration management.

We've actually used both Red Hat Enterprise Linux (RHEL) Image Builder and system roles. We currently use Red Hat Enterprise Linux (RHEL) Image Builder to create a standard operating environment for provisioning virtual machines, and we use system roles for configuring the machines at scale.

Red Hat Enterprise Linux (RHEL) offers enterprise security and really well-formed documentation.

Red Hat Enterprise Linux (RHEL) has positively impacted our organization by allowing us to standardize a lot, and the enterprise-level support that we get from Red Hat is really helpful. It really helps with the ability to standardize on the specific solution that we use to deliver Red Hat Enterprise Linux (RHEL) access to our customers.

The most important security feature in Red Hat Enterprise Linux (RHEL) is the errata data, which is really the most important part of security in Red Hat Enterprise Linux (RHEL) because it tells you exactly which component is vulnerable, which versions of Red Hat Enterprise Linux (RHEL) are affected, and overall, it's really well documented as a whole.

Red Hat Enterprise Linux (RHEL) has helped to mitigate downtime and lower risk by providing kpatch, kernel patches, which allow us to patch the kernel while it's running, without us having to do a full system reboot.

The knowledge base offered by Red Hat Enterprise Linux (RHEL) is really helpful and I'm really happy with the fact that it's also possible to download an offline version of it. I do wish that it would be updated more often.

Sometimes the support for Red Hat Enterprise Linux (RHEL) could be better. Since we're in a disconnected environment, it's really hard to share explicit details about the support case. For example, we keep getting asked for an SOS report, which we cannot supply. There's a real barrier between the problem and the help desk.

I do wish that the knowledge base would be updated more often.

I've been working there for seven years.
