Let’s dive in and explore the blueprint of great software systems! ??
Discover the foundational principles that power scalable, resilient, and future-proof software systems.
Software Architecture Terminology: The Blueprint of Software Systems
- Architecture Patterns: Reusable solutions to common design problems (e.g., Microservices, Monolithic, Event-Driven).
- Component: A modular, reusable part of a system with a well-defined interface.
- Module: A self-contained unit of functionality within a software system.
- Layered Architecture: Divides the system into layers (e.g., Presentation, Business Logic, Data Access).
- Microservices: An architectural style where applications are built as a collection of small, independent services.
- Monolithic Architecture: A single, unified system where all components are tightly coupled.
- Event-Driven Architecture: A design pattern where system components communicate via events.
- Service-Oriented Architecture (SOA): A design approach where services are provided to other components via protocols like HTTP.
- API Gateway: A server that acts as an entry point for managing and routing API requests.
- Scalability: The ability of a system to handle increased load by adding resources.
- Resilience: The ability of a system to recover from failures and continue functioning.
- Technical Debt: The cost of rework caused by choosing quick fixes over optimal solutions.
System Design Terminology: ?Designing Scalable and Efficient Systems
- Load Balancer: Distributes incoming network traffic across multiple servers to ensure reliability and performance.
- Caching: Storing frequently accessed data in memory to reduce latency and improve performance.
- Database Sharding: Splitting a database into smaller, more manageable pieces to improve scalability.
- Replication: Copying data across multiple servers to ensure availability and fault tolerance.
- Consistency Models: Rules governing how data updates are propagated in distributed systems (e.g., Strong, Eventual Consistency).
- CAP Theorem: States that a distributed system can only guarantee two out of three: Consistency, Availability, Partition Tolerance.
- Message Queue: A system for asynchronous communication between services (e.g., Kafka, RabbitMQ).
- Distributed System: A system where components are located on different networked computers.
- Fault Tolerance: The ability of a system to continue operating despite failures in some components.
- Latency: The time taken for a request to travel from the sender to the receiver and back.
- Throughput: The number of requests a system can handle in a given time period.
Technical Architecture Terminology: The Foundation of Technical Systems
- Infrastructure as Code (IaC): Managing and provisioning infrastructure through code (e.g., Terraform, CloudFormation).
- Containerization: Packaging applications and dependencies into containers for consistency across environments (e.g., Docker).
- Orchestration: Automating deployment, scaling, and management of containerized applications (e.g., Kubernetes).
- Cloud Computing: Delivering computing services over the internet (e.g., AWS, Azure, GCP).
- Virtualization: Creating virtual versions of hardware, operating systems, or storage devices.
- DevOps: A culture and set of practices that combine software development and IT operations.
- CI/CD Pipeline: Continuous Integration and Continuous Deployment for automating software delivery.
- Edge Computing: Processing data closer to the source of data generation to reduce latency.
- Serverless Architecture: A cloud computing model where the cloud provider manages server infrastructure.
- API (Application Programming Interface):A set of rules and protocols for building and interacting with software applications.
- Middleware: Software that connects different applications or components in a distributed system.
Solution Architecture Terminology: Designing End-to-End Solutions
- Stakeholder: Individuals or groups with an interest in the success of a project (e.g., clients, users, developers).
- Business Requirements: The needs and goals of the business that a solution must address.
- Functional Requirements: Specific behaviours and functions a system must perform.
- Non-Functional Requirements (NFRs): Quality attributes like performance, scalability, security, and usability.
- Use Case: A description of how a system interacts with users or other systems to achieve a goal.
- Proof of Concept (PoC): A small project to test the feasibility of a solution before full-scale implementation.
- Minimum Viable Product (MVP): A version of a product with just enough features to satisfy early users and gather feedback.
- RoadMap: A high-level plan outlining the steps to achieve a solution’s goals.
- Gap Analysis: Identifying the difference between the current state and the desired future state.
- Trade-off Analysis: Evaluating the pros and cons of different design options to make informed decisions.
- Vendor Evaluation: Assessing third-party solutions or services to ensure they meet requirements.
- Integration Architecture: Designing how different systems and components will work together.
Commonly Used Tools and Frameworks
- UML (Unified Modeling Language): A standardized modelling language for visualizing system designs.
- TOGAF (The Open Group Architecture Framework): A framework for enterprise architecture development.
- Zachman Framework: A taxonomy for organizing architectural artifacts.
- Agile Methodology: An iterative approach to software development and project management.
- Scrum: An Agile framework for managing complex projects.
- Kanban: A visual workflow management method for optimizing processes.
