new to server management, how do you handle website maintenance?

hey everyone, i just launched my first saas application and honestly, i'm realizing the whole world of ongoing website maintenance and cpanel management is a bit daunting. it's my first time really managing live sites and i'm feeling pretty overwhelmed by all the backend tasks needed to keep things running smoothly. i'm particularly unsure about what are the essential cpanel and general website upkeep routines i should be doing. i'm really concerned about overlooking critical tasks or making silly errors just because i'm so new to all this.

so, for those of you with more experience, how do you guys handle your website maintenance and server upkeep effectively, especially when you're starting out as a beginner? are there any specific tools or strategies you'd recommend to make this whole process less scary? any advice would be super helpful
