Welcome back to the "50 Days Software Architecture Class" on YouTube! This is Day 1, moderated by Anastasia and Irene. To make the session more engaging and collaborative, we've updated the scripted texts to include dialogue and contributions from both moderators on most slides. This adds interaction while keeping the total length within 15-20 minutes (approximately 60 words per minute, total word count ~1200 when delivered with natural pauses and transitions). Anastasia still leads slides 1-7 (intro and definitions), Irene leads slides 8-18 (importance, scalability, tools, and practices), and slides 19-20 are fully shared for recap and closing. Now, each slide includes interjections or follow-ups from the non-leading moderator to create a conversational flow. Pauses, transitions, and visuals will fill the timing.Support us with https://buymeacoffee.com/dailyaiwizard
