In this deep-dive lesson we explore why edge computing is exploding in 2026 and beyond. Learn how processing data closer to the source is transforming latency, bandwidth, privacy, and scalability in everything from autonomous vehicles and smart cities to industrial IoT and real-time AI.

We cover:

• Core concepts of edge computing

• Edge vs Cloud vs Fog architectures

• Real-world use cases and success stories

• Key technologies (5G, Kubernetes at edge, AI inference)

• Challenges, trade-offs, and anti-patterns

• How edge will reshape software architecture in the next decade

Homework included + full comparison with previous case studies (Netflix, Uber, Amazon).

If you’re building modern systems, this lesson is essential.

In Day 42 of the 50 Days Software Architecture Class we analyze Netflix’s legendary microservices architecture.

Discover how Netflix evolved from a monolithic application to over 1,000 independent microservices that power one of the world’s largest streaming platforms. We break down key components including:

Eureka for service discovery

Zuul as API gateway

Hystrix for resilience and circuit breaking

Chaos Engineering with Chaos Monkey

Spinnaker for continuous delivery

Global multi-region architecture

Observability, caching, and cost optimization

Learn the real-world patterns, principles (“You build it, you run it”), and lessons that made Netflix’s system incredibly scalable and resilient.

Homework: Pick one Netflix pattern (e.g. circuit breaker or chaos testing) and sketch how you would apply it to your current project.

In today’s in-depth lesson we explore how compliance and governance have become core architectural concerns. Learn how to design systems that are compliant by design rather than trying to retrofit regulations later.

You’ll learn:

Why compliance must be embedded into architecture from the start

Deep dive into GDPR principles and how they map to architectural decisions

SOC 2, HIPAA, and other key standards

Architectural patterns for data protection, access control, auditing, and breach notification

How to document compliance decisions using ADRs

Practical governance frameworks and a 30/90-day compliance roadmap

Balancing compliance with cost, speed, and innovation

Homework:

Review one of your current systems against GDPR’s key principles (data minimization, consent, right to erasure, etc.) and identify at least two architectural improvements you can make.

In today’s lesson, we dive deep into one of the most practical and impactful topics in modern cloud architecture: how to dramatically reduce your cloud bill without sacrificing performance or reliability.

You’ll learn:

• Why cost optimization is now a core architectural concern (not just an ops task)
• How to identify and eliminate the most common cloud cost pitfalls
• Right-sizing instances with real tools and calculations
• Auto-scaling strategies (target tracking, predictive scaling, Spot Instances, Karpenter, warm pools)
• Reserved Instances vs Savings Plans – including break-even analysis and commitment strategies
• Storage optimization, data transfer cost controls, and FinOps best practices
• A practical 30/90-day roadmap you can start implementing immediately

By the end of this video, you’ll have concrete formulas, policy examples, and architectural patterns that can help you save 30–70% on your cloud costs — just like many successful companies have done.

Homework:

Pick one of your production workloads, run a cost analysis, and identify at least three optimization opportunities (auto-scaling policy, reserved instance recommendation, or storage tier change).

Welcome to Day 39 of the "50 Days Software Architecture Class"! Moderated by Anastasia and Irene, today we explore Deployment Strategies — focusing on blue-green deployments, canary releases, and other zero-downtime techniques that let you update production systems safely and confidently. This 18–22 minute lesson (~1950–2100 words at 60 words per minute) features much longer, in-depth explanations, real-world rollout examples, risk mitigation, feature flags, rollback strategies, and how these patterns integrate with your overall architecture.

We’ve structured it into 20 main slides (each with 4 bullet points + extended Anastasia & Irene dialogues for depth). Anastasia leads slides 1–5 & 11–15 (foundations, blue-green, and canary), Irene leads slides 6–10 & 16–18 (advanced patterns, tools, and governance), and slides 19–20 are shared. This builds directly on Day 38’s testing strategies (your safety net during deployments), Day 37’s legacy modernization, Day 36’s ADRs (document every deployment decision), Day 28’s resilience patterns, and Day 20’s cloud-native architecture. Expect clear diagrams of blue-green traffic switching, canary rollout curves, and practical homework.

Welcome to Day 37 of the "50 Days Software Architecture Class"! Moderated by Anastasia and Irene, today we dive deep into refactoring legacy systems and practical strategies for modernizing monolithic codebases. This 18–22 minute lesson (approx. 60 words per minute, total ~1950–2100 words with significantly expanded, detailed explanations, real-world examples, step-by-step migration patterns, risk mitigation, tools, and case studies) is designed for production-ready learning. We’ve structured it into 20 main slides (each with 4 bullet points + much longer Anastasia & Irene dialogues for richer depth) plus Slide 0 (Oliver welcome) and Slide 21 (Oliver recap/ad). Anastasia leads slides 1–5 & 11–15 (foundations, assessment, and core patterns), Irene leads slides 6–10 & 16–18 (advanced techniques, tools, and execution), and slides 19–20 are shared. This builds directly on Day 36’s Architectural Decision Records (use ADRs to document every refactoring decision), Day 35’s ML integration, Day 26’s API Gateway, Day 7’s microservices, and Day 23’s hexagonal architecture. Expect diagrams of the Strangler Fig pattern, incremental migration roadmaps, code smell examples, and practical homework. Pauses for visuals and transitions keep the video engaging and actionable.

Welcome to Day 36 of the "50 Days Software Architecture Class" on YouTube! Moderated by Anastasia and Irene, today's focus is on Architectural Decision Records (ADRs) — a lightweight yet powerful practice for documenting significant architectural decisions, capturing context, alternatives considered, trade-offs, and rationale, so teams can understand why choices were made and evolve systems responsibly over time. The session is designed to run 18-22 minutes (approximately 60 words per minute, total word count ~1950–2000 with natural delivery and significantly expanded explanations, real-world templates, best practices, tools, integration patterns, and anti-patterns). We've organized it into 20 slides, each with 4 bullet points and much longer, more detailed conversational scripts from both moderators to offer richer context, practical examples, decision frameworks, and strategic guidance. To ensure more equal time distribution, Anastasia and Irene alternate leading sections more evenly: Anastasia handles slides 1-5 and 11-15 (intro, ADR fundamentals, and templates), Irene leads slides 6-10 and 16-18 (advanced usage, tools, and best practices), and slides 19-20 are shared for recap and closing. This builds on Day 35’s Machine Learning integration (where ADRs are essential for documenting ML choices), Day 34’s Big Data architecture, Day 23’s hexagonal architecture, and aligns with Day 2’s SOLID principles for maintainable, evolvable systems. Pauses, transitions, and visuals (including ADR templates, decision trees, and evolution diagrams) will enhance the flow and aid in adopting ADRs effectively.
