Real-Time vs Near-Time: Making the Latency Tradeoff

David Abaev — Sat, 07 Jun 2025 10:06:48 +0000

🧠 Everyone wants “real-time,” but do you really need it?
In this deep dive, I explore Real-Time vs Near-Time latency choices — when to stream, queue, poll, or batch.
Includes real-world examples, C# code, decision matrix, and architecture tips.

The Return of the Modular Monolith

The Return of the Modular Monolith
Microservices aren’t always the answer.
Sometimes, the smartest architecture… is one deploy.
With strict boundaries. Clean contracts. No distributed pain.
🧱 Modular Monolith =
✅ Fast dev
✅ Clear domains
✅ No premature ops overhead
✅ Easy to test + refactor
✅ Future-ready for microservices

💡 In .NET? Use:

InternalsVisibleTo for encapsulation
DI modules per domain
Lean shared kernel (e.g. IClock, ITenantService)
Don’t break things apart yet.
Just don’t build a ball of mud. 👊 Monoliths aren’t dead — just misused.

Build .NET libraries like a pro: clean, pluggable, provider-based. The OSS way extensible by design.

Build .NET libraries like a pro: clean, pluggable, provider-based. The OSS way → extensible by design.

Chaos in Production? Bring it on.

🚀 Chaos in Production? Bring it on.
In this post, I built a resilient microservice architecture in Go to test how real systems behave under failure. 💡 Two services: transaction-service and ledger-service ⚙️ Tech stack: Go + Kafka + PostgreSQL + Kubernetes 🎯 Injected real failure using Chaos Mesh — randomly killing pods to simulate crashes.
📊 The result? Clean retry logic, no data loss, and bulletproof consistency even under stress.
🧪 Plus: a clean architecture, full Docker + K8s setup, and a step-by-step breakdown in the blog.
👉 Ideal for backend engineers, SREs, or anyone who cares about real-world reliability.

Ten Signs Your Microservice Is Too Big — And What That Says About Your Understanding of Microservices

David Abaev — Thu, 24 Apr 2025 18:41:43 +0000

If your "micro" service knows too much, does too much, and changes too often — it’s not a microservice, it’s a monolith in disguise.
This post breaks down the red flags and what they reveal about how you really think about microservices.
💥 Time to cut the fat and refactor smart.

🚫 Microservice Anti-Patterns to Avoid
Real stories. Real mistakes. Real fixes.
Learn from production chaos so you don’t repeat it.
💥 Avoid the traps. Architect smarter.

Remote Configuration and Feature Flags

David Abaev — Wed, 16 Apr 2025 04:09:37 +0000

Why redeploy when you can toggle like a boss?
Why hardcode configs when you can change them live, 🧙‍♂️
🔁 Feature Flags – flip features ON/OFF per user, per environment
📦 Remote Config – change app behavior without redeploying, powered by IOptionsMonitor

Who’s the leader? 🧑‍⚖️

Who’s the leader? 🧑‍⚖️
In a distributed system, that’s a real question.
Here’s how I implemented leader election in .NET microservices 👇
