Why Do Businesses Pick SUSE Linux Enterprise Server (SLES)?
A lot of companies stick with SLES for some solid reasons. First, you get long-term support—up to 10 years of updates and security fixes with each version. That’s peace of mind you don’t find everywhere.
- Then there’s high availability. SLES comes with clustering tools built in, so your critical apps keep running and handle failovers automatically. No one likes downtime.
- Managing everything is easier, too. With SUSE Manager, you control updates, settings, and compliance from one place. It saves time and cuts down on headaches.
- SLES is also built for compatibility. It’s certified to work with heavy hitters like SAP, Oracle, and Microsoft, so you don’t have to stress about integration.
- And it’s flexible. Whether you’re on x86, ARM, POWER, or IBM Z, SLES runs smoothly across all of them.
It’s more than just a server OS. SLES gives you a solid base for cloud services, virtual machines, containers, and even edge devices. It’s the backbone a lot of businesses count on.
