One significant challenge is operational issues. When such issues arise, sometimes they can be attributed to bugs in the platform itself or in OpenShift. In a context where thousands and millions of customers rely on this platform daily, downtime is not an option. Upgrades are particularly challenging as they often involve major OpenShift upgrades to address specific product bugs. This can lead to delays and a complex upgrade process, requiring meticulous attention to operational configurations. Also, scaling can be problematic in high-traffic environments. Auto-scaling and managing pod scaling in the microservices architecture, a core feature of IBM Cloud Private, can pose challenges, especially when dealing with larger volumes of traffic.
