Java Reference
In-Depth Information
• The architecture does not use any entity beans (EJB 2.1).
This increases the amount of objects created in memory and
would enhance scalability.
Availability
The following mechanisms were recommended for Zamco
Application architecture to achieve high availability:
• Application is designed with a hot stand-by configuration
for high availability.
• Incase the primary servers goes down the load balancer will
be able to route the request to secondary / hot standby nodes.
• The load balancer can be configured to route traffic to hot
standby in case the primary reaches is capacity threshold.
• Stateless design - When a particular stateless server fails, its
work can be re-directed to a different server instance without
implications for state management.
Security
The following mechanisms were recommended for Zamco
Application architecture to achieve required security:
• The security will be provided through DMZ using inner and
outer firewall. Application and Database servers will be
behind the inner firewall and the web server will be behind
outer firewall in the DMZ.
