A transformative journey into the realm of system design with our tutorial, tailored for software engineers aspiring to architect solutions that seamlessly scale to serve millions of users. In this exploration, we use the fictitious MarsExpress, a local delivery startup in Albuquerque, as a model to illustrate the evolution from a community service to a global force.
MarsExpress, our focal point, currently operates on an aging monolithic system — a legacy structure that once served its purpose locally but now yearns for a comprehensive overhaul. Join us as we unravel the intricacies of system design, not merely for theoretical understanding but as a hands-on approach to rejuvenating a legacy system into a globally scalable software solution.
