Topologies
In today's globalized world, modern organizations face a lot of opportunities and challenges every day. Many of these challenges can put an onus on the organization's IT infrastructure therefore its configuration is crucial. The Apache Geronimo application server supports small-to-medium-sized enterprise applications and provides robust, secure support for the latest J2EE specification. This section will highlight the different configuration options that can be used in your production environment.
Two-tier system
The figure below shows illustrates a client machine accessing an application hosted in the Geronimo server. Althougth the figure depicts only one client machine, several machines can be connected to the server and users on these machines can access the hosted Web applications using a standard Web browser.
The client-side application can may vary ranging from being a simple command line user interface to a full-fledged user interface such as those created using popular client-side GUI technology. These applications can access the Web tier by connecting to the server using their own HTTP connections, or they can access business and EIS tier objects through the help of the Geronimo client application container.
Features of the Geronimo application client: -
- Seperate from the Geronimo server.
- Communication with the Geronimo server is over the network.
- Provides mapping , dependency management for the client application and reference resolution.
Three-tier system
Three tier architecture system is more scalable than two tier as it supports hundreds of users and organizationorganizations. It also increases flexibility and freedom.

The Apache Web server is the best, and most preferredpopular, HTTP server software in use on the Internet today. In your production enviroment using Geronimo with the Apache Web server would give you some rigorous advantages as given below.
- Clustering & Load Balancing
Clustering allows an application server to support multiple nodes with failover, session data sharing, and load balancing across many network nodes. Load balancing of the application can be done with the help of inbuilt support of Apache server.
- SSL Encoder
The advantages of Web server proxies are that they offer a way to get server affinity for SSL-encrypted messages, without any extra hardware. But extensive SSL processing puts an extra load on the proxy. It will be handled by Apache server while Geronimo can handle business logic of the application.
- Application Load Sharing
In many serving systems, Apache web and Geronimo application servers work together to handle all HTTP requests. Apache handles the request for static pages (including HTML, JPEG, and GIF files), while Geronimo handles requests for dynamic pages (JSPs or servlets) with the help of Tomcat/Jetty. Geronimo servers can also handle static pages, but in combined systems, they 're are usually set up configured to handle dynamic requests.
Summary
Using the Geronimo application server lets you build a secure enterprise infrastructure conforming to the latest standards and requirements. This article gave you an insight into custom configuration of the standard Geronimo installation, with several installation methods.
