Online shopping is becoming the prominent sales channel in the retail industry, even for the ones who are traditional with a brick-and-mortar history. This necessitates that the website provides the best in class user experience to the customers. User experience is not only about the layout and eye-catchiness of the website, but the responsiveness, optimally with sub-millisecond responses. Recent surveys indicate that 9 out of 10 users have responded that they will abandon a website if it is not responsive.
One of the major challenges for achieving great responsiveness is the bottleneck introduced by the data layer. It becomes very challenging to design the persistence storage layer to provide the required response performance. A proven way to enhance the data layer responsiveness is to introduce a caching layer on top of the persistence storage. Redis is the industry-leading enterprise-grade caching provider with great performance and scalability.
