Question

For this week’s assignment, you will be providing detail on the overall system integration architecture and the implementation framework.

New ContentProposed System Integration Components Architecture

Thoroughly describe the architecture of the proposed integrated system, including all interfaces and components for the system integration and deployment.

Represent this architecture diagrammatically.

Discuss which components and interfaces could be acquired and those that need to be developed from scratch.

Implementation Framework

Select and describe in detail the framework that you used to define and implement the system integration project.

Define the project in terms of the selected framework.

Discuss advantages for using the selected framework.

Discuss integration challenges that were highlighted by defining the framework.

Explanation / Answer

Integration is a key concern for today's increasingly heterogeneous, distributed ecosystem of enterprise applications. As diversity in the enterprise application technology landscape, and points of integration increase, users' expectations of coherent, uniform accessibility to data, services and business processes—across applications and access points—are growing dramatically.
As these trends progress, traditional methods of point-to-point application integration become increasingly untenable. The brittleness, redundancy, and inefficiency inherent in these approaches represent a significant threat to the Mosaic project—from an implementation timeframe perspective, as well as the long-term robustness and manageability of the environment.
Integration Goals
The following represent the high-level objectives of UA integration efforts:
Rapidly deliver reliable, sustainable and manageable solutions for inter-application and infrastructure integration
Eliminate, or reduce as much as possible, the brittleness and redundancy inherent in "one-off" point-to-point integrations
Balance long-range architectural vision with short-term tactical needs
Facilitate integration standardization, reuse and best practices across all Mosaic project initiatives
Defining the Scope of Integration
The scope/purview of "integration," for the purposes of the Mosaic project, will be a subset of what is often associated with "EAI" (Enterprise Application Integration) and "SOA" (Service Oriented Architecture) frameworks. Some applicable areas include:
Identification of application integration points
Exposing application components as externally "consumable" services
Service interface definition
Service discovery, governance and life-cycle management
Service composition and orchestration
Integration with "infrastructural" services (identity management, directory services, etc)
Data synchronization/propagation across applications
Connectivity—protocol adapters, connectors, bridges/gateways
Data/content formats and transformations (semantic integration)
Message generation, routing and delivery patterns (synchronous, asynchronous, pub/sub, "fire-and-forget", idempotent, event-driven, transactional, etc)
Message integrity and security (transport security, encryption, digital signatures, etc)
The Role of UITS' "Systems Integration and Architecture" (SIA) Team
The following represent the primary responsibilities and objectives of the SIA team, within the scope of the Mosaic project:
Consult with the technical leads of the various project initiatives to identify integration concerns, drivers, requirements and priorities
Identify commonalities across project initiatives to assist in architecting common integration components/frameworks
Develop integration tasks and roadmap/milestones to be integrated within Mosaic project plan
Develop and maintain relevant artifacts, such as best practices, reference architecture, design patterns and service metadata
Architect and implement integration "middleware", such as a service registry, service bus, identity management, authentication/authorization frameworks, as well as common ("infrastructural") services related to integration
Liaise with technical leads to identify appropriate integration patterns, opportunities for service reuse, and best approaches to addressing integration challenges
Consult with/train project developers on technical integration tasks
