System Design For Starting Up In One Shot 🔥
🎥 In this video, I will go in-depth on how to design a growable, scalable and robust system.
✴️ Instead of creating a distributed system from starting, we will start from a Monolith service and design it in such a way that it is highly growable and can be easily broken into microservices.
✴️ We will explore various ways to design the system and try to find the best way for a particular use case.
✴️ We will start by designing the monolith service with a very naive approach with minimal resources and will try to enhance the system progressively.
✴️ In this video in order to cover as many topics/concepts, I have taken an example of designing a Social App(like Instagram and Linkedin).
✴️ Initially, one monolith service will be responsible for all functionalities - Authentication, Posts, Likes, Notifications, User feed and Payments. Slowly we will try to make the system fast and scalable using vertical/horizontal scaling which will be accompanied by adding more components in the system including Message Brokers, Webservers, Reverse Proxy, Load Balancers, Background workers, Cache etc.
✴️ Also, we will try to cover each and every edge case while designing any service.
✴️ Will try to make a robust payment system by keeping every edge case possible in mind.
✴️ We will see when and how to use Database Transactions and Database Locks.
