Let's face it, folks. Upgrading your operating system can feel like wrangling a particularly stubborn llama across a cactus patch.

| Advantages Of Rhel 8 Over Rhel 7 |
Say "Adios" to Yesterday's Kernel, Howdy to Modern Marvels!
RHEL 8 boasts a much newer kernel (version 4.18 compared to 3.10 in RHEL 7). That means better support for all your shiny new hardware, along with some serious performance improvements. Think of it as the difference between a sluggish donkey and a sleek racehorse. You'll be running circles around your old system, leaving competitors in the dust (or shall we say, llama dung?).
Security So Tight, Even Paranoid Penguins Would Be Proud
RHEL 8 takes security to a whole new level. We're talking system-wide crypto policies, improved encryption algorithms, and the removal of some, well, let's just say "questionable" security practices from the past. It's like your server finally hired a team of cyber ninjas to guard its virtual gates. Sleep soundly knowing your data is safe from even the most determined digital bad guys (unless they're particularly good at llama wrangling, that is).
Multiple Application Versions? RHEL 8 Says "Bring It On!"
Running multiple versions of the same application used to be a recipe for server headaches. But RHEL 8 throws a fiesta for flexibility with its Application Streams. Now you can keep your core system stable while deploying the latest and greatest applications without breaking anything. It's like having a buffet of software options, all waiting to be devoured by your server's insatiable appetite for efficiency.
Tip: Reread the opening if you feel lost.
But wait, there's more! RHEL 8 also offers a plethora of other benefits, including:
- Stratis Storage: This nifty tool simplifies storage management, making you look like a storage sensei in no time.
- Wayland Display Server: Enjoy smoother graphics and better multi-monitor support. Because who wants a desktop experience that feels like watching a slideshow?
- Control Group v2: Improved resource management keeps your system running like a well-oiled machine.
Basically, RHEL 8 is like that cool upgrade you didn't know you needed. It's faster, more secure, and packed with features that make your server life easier. So, ditch the drama and embrace the upgrade llama. Your servers will thank you (probably with a grateful whirring of fans).
