Software Architecture

Syllabus

Unit 1: Architectural Foundations and Quality Attributes

Definition and role of software architecture in system development lifecycle, Architectural structures (modules, components, connectors, deployment), Quality attributes (performance, availability, security, maintainability, scalability) and their trade-offs, Architecture Influence Cycles and decision making frameworks, Non-functional requirements elicitation and specification using scenarios and utility trees.

Unit 2: Architectural Styles and Patterns

Classification of architectural styles (layered, client-server, pipe-filter, event-driven, service-oriented), Microservices architecture principles and decomposition strategies, Model-View-Controller (MVC) and variations (MVP, MVVM), Architectural patterns (Broker, Blackboard, Peer-to-Peer), RESTful principles and API design best practices for distributed systems.

Unit 3: Component-Based and Service-Oriented Architectures

Component principles (cohesion, coupling, interfaces, contracts), CORBA/CCS component model vs. modern container-based approaches, Service-Oriented Architecture (SOA) fundamentals, ESB patterns and anti-patterns, Microservices orchestration vs. choreography, Domain-Driven Design (DDD) bounded contexts and context mapping.

Unit 4: Architectural Views and Documentation

4+1 View Model (Logical, Process, Development, Physical, Scenarios), UML 2.x structure and behavior diagrams for architecture representation, Architecture Description Languages (ADLs), Tool-supported architectural modeling (Enterprise Architect, ArchiMate), Documenting architectural decisions using ADRs (Architecture Decision Records).

Unit 5: Architecture Evaluation and Evolution

Architecture Tradeoff Analysis Method (ATAM), Software Architecture Analysis Method (SAAM), Scenario-based evaluation techniques, Risk-driven architecture evaluation, Refactoring legacy architectures, Evolutionary architecture principles (fitness functions, strangler pattern), Cloud-native architecture migration strategies.

Practicals

Lab 1: Quality Attribute Scenarios: Focuses on eliciting and documenting non-functional requirements using quality attribute scenarios for a case study system, creating utility trees and prioritizing trade-offs.
Lab 2: Architectural Style Analysis: Focuses on analyzing existing systems to identify applied architectural styles, documenting style characteristics and limitations through reverse engineering exercises.
Lab 3: Microservices Decomposition: Focuses on decomposing monolithic applications into microservices using domain-driven design techniques, identifying bounded contexts and service boundaries.
Lab 4: MVC Implementation Patterns: Focuses on implementing the same business logic using different MVC variations across web frameworks, comparing controller responsibilities and view separation.
Lab 5: REST API Design: Focuses on designing and documenting RESTful APIs following HATEOAS principles, including resource modeling, HTTP methods, status codes, and hypermedia controls.
Lab 6: Component Interface Contracts: Focuses on defining and implementing component interfaces with versioning strategies, demonstrating contract-first design and interface segregation principles.
Lab 7: SOA vs Microservices Simulation: Focuses on implementing service communication patterns (synchronous RPC vs. asynchronous messaging) and measuring performance/scalability differences.
Lab 8: 4+1 View Modeling: Focuses on creating complete 4+1 architectural views for a medium-complexity system using UML tools, ensuring view consistency and scenario coverage.
Lab 9: Architecture Decision Records: Focuses on writing ADRs for architectural decisions in an evolving project, documenting context, decision, consequences, and status changes over time.
Lab 10: ATAM Evaluation Workshop: Focuses on conducting Architecture Tradeoff Analysis Method (ATAM) workshop on peer projects, identifying risks and documenting mitigation strategies.
