Implementação de um ambiente clusterizado com alta disponibilidade para sistemas java web utilizando docker

Abstract

Implementing a clustered environment for systems developed in Java has a certain difficulty, in addition to the various configuration files needed, perhaps the main problem is due to the need of more than one machine for this, even with virtualization, administering these machines is quite tiring , mainly due to the need to maintain multiple active operating systems. The proposed environment seeks to reduce these difficulties using Docker, which will act as a facilitator for its creation, without the need for several virtual machines, where they were replaced by containers. Will be presented an environment , such as application server Wildfly, Web server Apache HTTP and PostgreSQL DBMS, where after the implementation, the security problem of the previous scenario has been solved and proves the increased availability of the application through the load tests performed in both environments
