Cloud computing is currently everywhere and lots of companies are trying to move their Java EE applications to a cloud infrastructure to get agility with scalability, availability and security of their applications. Lightweight application servers are a perfect fit for running these type of Java EE applications. Apache Tomcat and Apache TomEE are popular cloud-friendly application servers for deploying Java EE applications. Nevertheless, there is a gap in providing a cloud-based operational SaaS platform to manage, monitor and troubleshoot these type of servers.

A lot of enterprise companies use Apache Tomcat and Apache TomEE to run their critical applications such as e-commerce, insurance or banking applications. They are very happy to use these servers (easy to use, install and configure) but when it comes to management and monitoring, they are faced with some complexity. ManageCat is launched to solve this problem. It provides a single complete SaaS platform to manage, monitor and troubleshoot these application servers from the cloud. ManageCat is an industry first Apache Tomcat and TomEE Operational SaaS platform, to take control of these application servers in just 5 minutes.
