Whiteboards are imperfect for complex distributed system design due to static diagrams, lack of version control, and limited space/time. They can lead to information gaps, misunderstandings, and inefficient collaboration.

Technical debt accumulates when dev teams prioritize quick fixes over sustainable code practices, slowing coding cycles, increasing maintenance costs and deteriorating software quality.

Communication is key in software development, but verbal explanations can lead to misunderstandings. Visual collaboration tools like Miro, Figma & Lucidchart help align teams on complex distributed systems, reducing errors and improving productivity.

Minimize dependencies, monitor perf & use std comm protos for backend design in distributed systems. Define structured design process & submit review before coding. Simplify communication between components.

Multi-cloud architecture ensures high availability & resilience by distributing workloads across multiple cloud providers. It optimizes performance, avoids vendor lock-in, and helps with compliance & cost management.
