In this edition, we dive into real-world system design, safe deployment strategies, a signed book giveaway, and the latest trends in software architecture ?
? How to Deploy Services Without Downtime
Deploying services can be risky. Choosing the right deployment strategy matters:
? Multi-Service Deployment
Simple to implement, but high risk — all services are upgraded at once, and rollbacks are complex.
? Blue-Green Deployment
Two identical environments: “blue” for staging, “green” for production. After testing, traffic is routed to the new version. Easier rollback, but expensive.
? Canary Deployment
Roll out updates gradually to small user groups. Safer and cheaper than blue-green but harder to monitor.
? A/B Testing
Multiple versions run simultaneously for user segments. Great for experimentation — but needs careful handling to avoid accidental exposure.
? Over to you – Which strategy do you use in production? Any horror stories?
? Google Docs: Real-Time Collaborative Editing Architecture
Designing a real-time editor like Google Docs isn’t trivial:
Clients send edits via WebSocket.
WebSocket Server manages real-time communication.
Operations go to a Message Queue for durability.
A File Operation Server applies collaboration algorithms.
Data stored: metadata, content, and edit history.
Conflict resolution algorithms include:
? Operational Transformation (used by Google Docs)
? Differential Synchronization
? CRDT (actively researched)
? Have you ever faced issues using Google Docs? What do you think caused them?
? Software Architecture Trends – What’s Changing?
Insights from InfoQ’s Architecture & Design Trends Report:
? "Data + Architecture" – Architects now consider data pipelines, quality & traceability alongside systems.
? Architecture is becoming a shared responsibility — not just for those with “architect” in their title.
? Asynchronous collaboration (like ADRs) is a positive shift from remote work culture.
? Better distributed teams = Better distributed systems.
? What trends are you seeing in 2022 and beyond?
Let’s connect and share insights on system design, cloud architecture, and engineering leadership!
