WhatsApp has to be one of those most easily scalable projects to work on. You have the freedom to divide chatrooms across different databases/shards. Same goes for notifications, where users can be divided since they're all isolated. The hardest part is just coordinating all the moving pieces in a way that can grow well, and that mostly just involves avoiding pitfalls in your design that might bottleneck. |
