GOTA SERVER ARCHITECTURE
1. Introduction:GOTA is designed in distributed architectural
manner. Each server configured and tested for scalability
requirements. For example if web server receives too many
requests from users and becomes
exhausted, technical team could able to add another horizontal
node behind the network load balancer
without any scalability problem.
2. Server List: GOTA currently contains four main server types
like web, gate, accreditation,database and two optional
server/service types like is messenger, LB. There will be some
server types will be develop in future like UIMA server and gate
cloud server. Each server couldbe configured from web server.
