Description

Designing, developing and deploying enterprise class applications involves a set of challenges that traditional non-enterprise developers seldom have to address. Enterprise-class applications typically require high-availibility, concurrent access from a large number of users, several levels of authentication and authorization enforcement, encrypted communications, remote (networked) access, database access (including multiple databases), trasactional integrity, asynchronous communications and messaging, scalability and reliability.

Modern enterprise-class applications, additionally, also have to provide access to their functionality over the web to browser-based clients, mobile devices, web services clients and to any of the myriad devices that will be introduced in our ever-changing environment.

In addition to the enterprise application services listed above, the application developer still has to design and implement her core application logic that pertains to her domain (e.g. banking, insurance, healthacare, transporation, entertainment etc.).

While all the enterprise-class features we listed above are important, it is unrealistic that a single application developer will have the mastery of all those services; in fact each of those services typically have their own experts who specialize in that one single aspect (e.g. security, etc.).

A quick survey of various enterprise-class applications also reveals, that while these applications might differ significantly in the core functionality they provide (e.g. an on-line healthcare system is going to be significantly different from an on-line shopping site), the enterpise-class services needed by them will be quite similar modulo some configurable customization. What this means is that there is a significant opportunity to expolit the common aspects of these applications by refactoring the enterprise-class services. This implies that an enterprise-class application developer does not have to implement these services over and over again.

Enterprise application frameworks such as Java Enterpise Edition and Microsoft .NET are two of the many such frameworks that provide these commonly used enterprise-class services through high-level interfaces. The application developers, deployers and administrators can now avail themseleves of these services without coding for those services. These services are typically implemented by experts in those areas (e.g. security, transactions, database, communication, etc.)

This course has been specially designed for professionals seeking to understand the architecture of enterprise application servers and frameworks. This course also covers the architecture and use of various systems used in developing and deploying enterprise-class systems such as database management systems, messaging systems, directory servers such LDAP, transaction coordinators, security frameworks and web servers.

This course also introduces various architectural patterns used in building enterprise-class systems such a client-server and n-tier.

This class includes lectures, presentations and demonstrations of the concepts introduced in the class.

Objectives

This course aims to introduce to the audience the architecture of enterprise application servers and the eco-system in which these servers reside. The course also aims to introduce design and architctural patters and best practices for the implementation of robust, scalable, secure, persistence-aware, web-enabled and transactional enterprise applications. On completion, attendees would be able to:

Understand the role enterprise application servers play Java EE 5
Understand the architecture of enterprise application servers and frameworks
Understand the architecture of web application servers and frameworks
Learn how database systems interact with the application servers
Learn how messaging systems interact with the application servers
Learn how directory servers such as LDAP servers are utilized by enterprise applications
Learn how security is enabled and enforced by enterprise applications
Learn how web services may be served and consumed by enterprise applications
Understand the client-server architecture
Understand the N-tier architecture
Learn the best practices and design patterns for building enterprise applications
