Run-time Architecture

Appeon for PowerBuilder deploys your 4GL Web project to the n-tier Web architecture and J2EE application server. The presentation tier, business tier, and data tier are logically separated. The three tiers can run on the same physical server or be separated onto multiple servers and clustered. You can take advantage of numerous security mechanisms, including SSL/HTTPS, VPN, Firewall and Web browser security. No matter how small or large your organization is, you will realize the benefits of greater availability, scalability, security, and reliability.

	Web Browsers
	The Web browser runs the presentation layer of the Web application. The presentation layer is comprised of a set of HTML, XML, and JavaScript files. The Client and Server exchange all data over the standard HTTP/HTTPS protocol.



	Firewall
	Port 80 is supported to comply with corporate firewall requirements.



	Web Servers
	The Web server hosts the presentation layer for the migrated Web application.



	J2EE Application Servers
	Appeon Server provides Load Balancing services. Appeon Server hosts the business and data access logic for the Web application and the Appeon Server.



	Database
	Your existing JDBC-compliant database can be used for the Web application.
