I own a small business that runs a website that services 401k plans. I have been in business for 30 years. 10 years ago I had a Java program developed that runs the web services. It is a Java J2EE web application running on Glassfish server with PostgreSQL database. I have an excellent developer who does enhancements to the program from time to time, but I want some backup in case this person is not available in the future. I am looking to establish a ongoing maintenance arrangement that would involve ongoing monitoring of the the program and fixing any problems. Can you help me with this.
