Online retail and e-commerce IT performance have significantly matured, transforming the once intense consumer traffic during Black Friday and Cyber Monday into a smoother, weeklong event with fewer technical issues reported. Retailers have improved digital performance by focusing on server-side response times and reducing reliance on third-party components, which has enhanced customer experiences. Dynatrace has been instrumental in this process by providing tools like Real User Monitoring (RUM) for session replay and Business Events for capturing real-time business data, helping retailers to better manage distributed applications and ensure seamless end-to-end user experiences. The use of session replay helps identify user experience issues, such as page rendering problems, while Business Events allow for more comprehensive business process analysis and automation. As the retail market evolves, retailers are expected to further enhance their application management across multiple technology providers, leveraging solutions like those offered by Dynatrace to maintain optimal performance and customer satisfaction.
