Software Architecture and System Design
For senior engineers moving into design ownership, this programme connects business constraints to architecture decisions. It spans quality attributes, monolith and service boundaries, data and consistency models, caching and messaging, capacity estimation, failure analysis, and reviewable decision records.
Overview
Practical learning for workplace transfer.
Architecture fails quietly. A system meets its functional specification, then buckles at three times the expected load, or a service split that looked clean turns every feature into a four-team negotiation. This programme trains the reasoning that prevents those outcomes: deriving quality attributes from business constraints, choosing boundaries by rate of change and data ownership rather than by org chart, estimating capacity before committing to a design, and analysing failure modes while they are still cheap to fix. Participants design a full system across the week and defend it in a structured architecture review.
Prerequisites
Several years of hands-on development experience and familiarity with at least one production system involving a database and an external integration.
Objectives
- Translate business constraints into prioritized, testable quality attribute scenarios.
- Choose between modular monolith, service, and event-driven structures on evidence.
- Select data stores and consistency models that match each workload's access pattern.
- Apply caching, queuing, and asynchronous processing without hiding correctness problems.
- Estimate throughput, storage, and latency budgets before committing to a design.
- Record and defend design decisions through architecture decision records and reviews.
Target audience
- Senior software engineers taking on design responsibility
- Solution and application architects
- Technical leads owning multi-team system boundaries
- Platform and integration engineers designing shared services
- Engineering managers accountable for system scalability
- Consultants and pre-sales engineers shaping technical proposals
Program outline
A clear structure for the learning journey.
Outline points are grouped in one designed block instead of being treated as separate module cards.
01From Requirements to Quality Attributes4 topics
- Turning stakeholder concerns into measurable scenarios with thresholds
- Trade-offs between performance, availability, security, and cost
- Constraints, assumptions, and the risks each candidate design carries
- Documenting drivers so later decisions can be traced back to them
02Structuring Systems: Monoliths, Modules, and Services4 topics
- Modular monolith versus distributed services: cost and readiness criteria
- Finding boundaries through data ownership and rate of change
- Coupling, cohesion, and interfaces that outlive a single release
- Layered, hexagonal, and event-driven structures compared
03Data Architecture and Consistency4 topics
- Relational, document, key-value, and time-series stores by access pattern
- Strong, eventual, and causal consistency explained in practical terms
- Transactions across boundaries: sagas, outbox, and idempotency
- Schema evolution, migration, and multi-version compatibility
04Performance, Caching, and Asynchronous Processing4 topics
- Caching layers, invalidation strategies, and stale-data tolerance
- Message queues, streams, and backpressure between components
- Capacity estimation: request rates, payload sizes, and storage growth
- Latency budgets across network hops and third-party dependencies
05Failure Modes, Resilience, and Operability4 topics
- Identifying single points of failure and blast radius per component
- Timeouts, retries, circuit breakers, and graceful degradation
- Observability by design: logs, metrics, traces, and health signals
- Disaster recovery objectives and what they actually cost to meet
06Architecture Decisions, Review, and Evolution4 topics
- Writing architecture decision records that survive team turnover
- Structured review: scenario walkthroughs and risk identification
- Communicating design to executive, delivery, and engineering audiences
- Planning migration paths and retiring architecture that no longer fits
Materials provided
- Course workbook, annotated code samples, and reference notes
- Hands-on lab environment and starter repositories
- Exercises, checklists, and reusable code templates
- 4D Certificate of Completion
- Post-course technical guidance
Training Options
Programs can be delivered in-house, online, or in a blended format depending on your team's schedule, location, and learning objectives. When an external certificate or exam is included, certification rules and fees remain under the relevant awarding body's policies, while 4D provides the training and preparation support.
Why choose 4D
4D structures this programme around a system your organization is actually planning or struggling to scale. The week produces a documented design with quality attribute scenarios, capacity numbers, and architecture decision records, reviewed by 4D architects against the failure modes most common in Gulf-region enterprise and industrial deployments.

Python Programming Fundamentals
A hands-on introduction to Python for engineers and analysts who need working code rather than tutorial fragments. Participants build fluency with data types, collections, functions, files, and error handling, then assemble a small program that reads real data and produces a usable report.

Designed for developers whose Python works but is difficult to change. The course covers dataclasses, generators, decorators, context managers, and type hints, then applies the refactoring moves that turn a nine-hundred-line module into small tested units guarded by black, ruff, and mypy.

Aimed at teams losing hours every week to repetitive file, spreadsheet, and reporting work. Participants automate those tasks with Python: batch file handling, Excel and CSV processing, REST API calls, email alerts, and scheduled jobs that run unattended and report clearly when something fails.
