Brief

This Framework is used to integrate various enterprise systems by means of events. The benefits of such integration are the following:

• Enterprise platform components based on Enterprise Integration Patterns;
• Data driven routing mechanism based on Apache Camel;
• Security authentication for external calls;
• Different data formats can be processed using standard and custom processors and transports;
• Sender does not need to know the destination address, it sends events to the mediator component and then it is properly routed and delivered to the destination;
• Mediator component will attempt to redeliver failed events until succeeds (or exceeds limited number of attempts), if a destination is not available at the moment;
• Flexible container start up configurations: standalone, ServiceMix, external application server (JBoss, Tomcat);

Architecture

Apache ServiceMix is used as an application server to host framework components. Persistent messaging is implemented using ActiveMQ JMS queue. Events persisted in a relational database (DB2 z/OS, MSQL, Oracle) for further retrieval. Web services are used for interaction with external endpoints.

The back-end application intends to support all internal business processes of one of the biggest and fast growing European e-commerce companies that provides online shopping in 10 countries. The e-commerce system that was launched 10 years ago has required re-engineering as well as maintenance and implementation of new features. The e-commerce application and back-end, as a part of it, is migrated to a new architecture that fits customer requirements to handle grown load and expanded market.

Architecture

The e-commerce system has a requirement for high-end transaction load and easy customization. Due to the requirements, a presentation layer is migrated to PHP with Zend Framework that helps designers to change and customize front-end easily and quickly. As well it helps to make front-end appearing more attractive for the end users. XML-RPC connects PHP front-end with a powerful business layer implemented in Java, Spring. Oracle 11g database is used as a data storage and accessed from the business layer via data access layer implemented in Hibernate. Web-application is run by Resin 3 application server.

Brief

The primary purpose of this product is to facilitate E-commerce sale and distribution of multimedia products (such as music, video, ringtones etc.), as well as to provide supporting services, like customer support, product management support, financial clearing, etc.
The media distribution platform is a light and fast framework with small overhead designed for customers with high-end transaction load and high availability requirements. It facilitates support for multiple presentation and business logic channels (can run two or more sites/interfaces (HTML, WAP, SOAP, etc.) for different retailers on the same backend (datastore, business logic).
For the system engineers it provides an extensive monitoring, administration and troubleshooting facilities.

Several web and mobile applications were created on this platform and deployed for different customers in Europe, Russia, China and India.

Architecture

The media distribution platform is a multi-tier platform where:

• Data storage: Oracle 10g
• Data access layer: Hibernate
• Business: EJB, JBoss
• Application server: JBoss
• Presentation: Struts
• Web server: Apache

The media distribution platform is integrated with different external components of the following types:

• Clearing house — provides content preparation/protection and license generation features.  It is utilized during purchase, download and license acquisition process.
• Authentication service — is an external service which provides user authentication. It is usually utilized for customers who have pre-existing customer base which has to be integrated in the e-commerce platform.
• Payment gateway — is an external service to process payment and billing requests.

Auditing facilities are becoming a basic requirement for compliance in many organizations. This system allows compliance administrators to monitor a real-time activity of the various services (web, administration, and end-user) and enables user sessions in different software solutions to create audit logs at all stages of operation. Auditing System is a generic auditing solution — one that can be used by Windows and Unix versions of client products.

Architecture

The system consists of client libraries, to allow multiple client applications to communicate with a single Auditing application. Client applications are capable to extend the set of audit message types by registering new types with the Auditing System. The system has the capability to register any audit message type that conforms to a generic message schema. Client applications can use Java or C++ Audit Client API´s to compose and send audit messages. On a receipt, the Auditing System stores the message in the database repository. Reliable and secure delivery of audit messages is affected by the use of SOAP, along with WS-ReliableMessaging (WS-RM).
