🔍 AIOps vs. DevOps
Can AIOps Replace the Whole DevOps? 🔄

A thread🧵👇 Image
1/ 💡 Culture Matters:

DevOps isn't just about tools; it's about teamwork and making things better together. AIOps helps with some tasks, but it can't fix team dynamics.

Example: In DevOps, developers and IT folks work closely to solve problems faster.
2/ 💻 From Idea to Reality:

DevOps handles everything from planning to getting the software out there. AIOps helps with some steps, but it doesn't cover everything DevOps does.

Example: In DevOps, everyone works together to build and release software smoothly.
