@thisisgraceshin: A 30-minute crash, 10 minutes before a crucial deadline. South Korea’s university application outage left some students unable to submit their applications and sparked a wider debate over how such a high-stakes digital system should be built and managed. Korea University Professor Heonchang Yu, who specialises in cloud computing and fault-tolerant systems, explained that predictable surges in traffic can be distributed across multiple servers through load balancing. And when failures do happen, critical services should be designed with redundancy so one problem doesn’t bring the entire system down. His other key point: moving the system from private to public hands doesn’t automatically make it more reliable. What matters is how well it is designed, tested, deployed and maintained. A useful look at the less visible infrastructure behind the digital services we depend on. #CNA #SouthKorea #Technnews #uway #CloudComputing

Great reporting Grace. A 30-minute crash 10 minutes before the deadline is every applicant's nightmare. That debate on how high-stakes systems should be built is so important. Thanks for explaining the fault-tolerant angle.
