Chapter 3 Design Middleware represents a collection of interconnected components that are distributed across different locations and provides features like reliability, scalability, and maintainability. Therefore, middleware makes application access easier. It provides load balancing servers, web servers, and application servers. CMS facilitates middleware infrastructure and supports application development and delivery. Figure 3-20. Middleware layer You should look into the various components of the middleware layer carefully while developing and deploying your DXP’s application, such as application monitoring, server monitoring, application logging, server logging, and auditing. As shown in Figure 3-20, the UI (front-end) applications will be deployed on a web server and the backend applications will be deployed on the application server. Backend applications have different layers and components, such as authentication and authorization, logging, and auditing. • Application monitoring ensures that application processes perform in an appropriate manner. • Server monitoring ensures health and availability of the server and OS; that includes bandwidth, CPU utilization, memory utilization, and disk utilization. 88
