Deploy a simple Java web app on Tomcat 10 using Java 11 and Jakarta Servlet API 6.0, deploy via the deployment directory, and test the login form in a browser.

Understand how Tomcat defines and uses context paths to access apps like /myapp and /myapp/v1 through host configurations, var files, and deployment options.

Manage deployed web applications with the Tomcat Manager's web and text interfaces, including starting, stopping, and reloading apps. Learn to deploy new war files and configure users for access.

Monitor Tomcat health and performance by tracking resource usage, response time, and error rate. Install VisualVM, enable Visual GC and MBeans, connect to Tomcat, analyze CPU, threads, and garbage collection.

Explore how context paths organize Tomcat deployments, how to deploy a web app via the var file or Tomcat manager, and how to monitor health with logs and key metrics.

Configure Tomcat connectors in server.xml, including an HTTP connector on port 8080 and an AGP connector on port 8009, with timeouts and redirect to HTTPS.

Configure Apache as a reverse proxy and load balancer for tomcat by setting up a virtual host, enabling modules, and balancing requests across back-end servers on ports 8080 and 8081.

Learn to harden Tomcat servers by enforcing non-root operation, strict permissions and umask, removing unused web apps, securing management interfaces, and evaluating the security manager during deployment.

Configure Tomcat authentication and authorization by defining users, roles, and a realm, using a file-based user database and memory realm, and securing resources via web.xml.

Configure ssl tls for secure communication in apache tomcat by obtaining or generating a certificate and setting a pem keystore. Update server.xml with ssl connector, then restart and test https.

Identify Tomcat performance bottlenecks by monitoring cpu, memory, disk I/O, network throughput, and thread pools, then optimize database queries, logging, and static content delivery.

Configure VisualVM and JMX remote monitoring to optimize Tomcat performance. Tune heap size and permanent generation space via setenv and env.sh, and monitor threads and memory with VisualVM.

Optimize Tomcat performance with connection pooling and thread management, choosing libraries, configuring pool properties, monitoring usage, and leveraging synchronous and asynchronous servlets for scalability.

Identify and optimize Tomcat performance bottlenecks, from inefficient queries to memory and thread contention, by tuning configuration, thread pools, caching, GC, and memory sizing, and using VisualVM, JMeter, and Prometheus.

Explore tomcat logging mechanisms and log files, including java util logging configured via conf/logging.properties and key logs like catalina.out and localhost access logs.

Diagnose and fix common Tomcat issues, including installation, configuration, deployment, memory, and connectivity, using logs, environment checks, and startup diagnostics.

Explore Tomcat logging with Apache Common Logging, logs directory, and Catalina dot out. Learn to integrate with external monitoring via JMX or management API, and optimize and secure log files.
