What are the benefits of Clean architecture? - Modularity - Separation of concerns - Testability of business logic - Improved team productivity - Loose coupling of components There's no "right" way to build software. You should decide what works for you. Clean architecture works well for me. I've used it to build excellent products. If you want to get started quickly, I've created a free Clean Architecture template. You can download it here: https://lnkd.in/ekMyTe3N

Microservices architecture has changed the way we build software. (But it’s not without its challenges.) By breaking a monolithic app into smaller, independently deployable services, microservices let teams develop, deploy, and scale faster. However… Microservices also bring a new set of problems you must solve: 1. Data Consistency and Eventual Consistency Data is often distributed across nodes (sometimes even globally). Result? Temporary discrepancies in data state → a phenomenon known as eventual consistency. 2. Security A bigger architecture = a bigger attack surface. Patterns like the API Gateway pattern are critical for securing microservices at scale. 3. Scalability and Database Performance It’s easy to scale application instances. Databases? Not so much. Without patterns like Database per Service or CQRS, your database can quickly become the bottleneck. The good news? There are proven design patterns that help tackle every one of these challenges. In this post (and series), we’ll break down: → The most popular microservices design patterns → When to use them → Benefits and hidden pitfalls you need to know If you're planning a microservices journey this year, this might save you months of headaches.

🎉 Big news and a gift for you 🎁 📢 THE NEWS: the 4th edition of “Node.js Design Patterns” is out today! When the first edition came out 11 years ago, Node.js was the new kid on the block. JavaScript was evolving fast, and many patterns were still taking shape. Since then the ecosystem has grown up. We got async and await, a shift to ESM, a stronger standard library, better tooling, and a culture that values testing, performance, and reliability. This new edition is our love letter to that evolution. ❤️ After more than a year of work, we rebuilt the book from scratch to reflect how modern Node.js is used in real projects. We refined and reorganized chapters, updated explanations, and added new material so you can go from strong foundations to production grade systems. What is new: • Modern JavaScript throughout, including ESM and async and await • A full chapter on testing with the built-in Node.js test runner, plus Playwright for E2E • Clearer guidance on scalability and distributed systems • Practical patterns for resilience, performance, and security • Fresh examples and a smoother structure from start to finish We also refreshed the website so you can quickly see what is inside, who the book is for, and how to get it. 🎁 THE GIFT The community has given us so much, so we want to give something valuable back. We are sharing our favorite chapter FOR FREE: Chapter 6, Coding with Streams. Streams are powerful and often underused. This chapter is 80 pages of practical insights that help you write faster, leaner, and more scalable Node.js code. 👉 Grab the free chapter and see what is new here: https://lnkd.in/e3keqCtC If it resonates with you, please share it with a friend or teammate who wants to level up their Node.js skills. Thank you for the support, and happy coding. #Nodejs #JavaScript #DesignPatterns #SoftwareArchitecture #WebDevelopment #Backend #Streams #Testing #Programming #Developers

Our book "Strategic Monoliths and Microservices" doesn't categorically (as an absolute) recommend modular monoliths. The key is in the subtitle: "Driving Innovation Using Purposeful Architecture." We provide a slew of reasoned principles and guidance on making sound architectural decisions while focusing on the actual two most important words in the main title and subtitle: "Strategic ... Innovation." We were hoping that leading with both of these words would frame the more important point of using DDD strategic design and enabling architecture decisions to reveal themselves as purpose is understood by stepwise refinement. Unfortunately, many still make a snap judgment based on the words Monoliths and Microservices.

When monoliths scale better than microservices. From the article (by Yash Batra): "Why the Industry Missed This: Narrative Momentum — Microservices became the default “modern” answer; engineers stopped questioning it." It is true. The microservice pattern was developed as a way to scale to millions of users. But it is a horrible compromise: it adds enormous complexity, because actions that would occur in a single transaction in a monolith are now separated into myriad separate transactions - the result is myriad failure modes which can be very complex to handle. The guidance should be to only decompose what you _MUST_ into separate runtimes and separate transactions. What you _MUST_, to _scale_ - no other reason. Decomposing things is good; decomposing into separate runtimes is _NOT_ good - you should do it when you _must_. https://lnkd.in/ePZ--E3m Yash Batra

What people think tech leads do: • Architect solutions • Lead teams • Make decisions What tech leads actually do: • Attend meetings about meetings • Explain why "Kubernetes" isn't the answer • Say no to impossible deadlines • Translate dev speak to business speak • Google "how to motivate developers" • Question life choices Tech Lead Morning Routine: 1. Coffee 2. Check if prod is down 3. More coffee 4. Cancel unnecessary meetings 5. Fail to cancel meetings 6. Attend unnecessary meetings 7. Wonder why no code gets written What's your tech lead survival tip? Share your pain below 👇 *** P.S. The secret is more coffee. Always more coffee. ☕

🚀 Clean Architecture in .NET – Scalable Project Structure Over the past few months, I’ve been building enterprise-grade .NET applications using Clean Architecture principles. The results? 🔸 Better scalability 🔸 Clear separation of concerns 🔸 Easier unit testing and maintainability Here’s how I structure my project for maximum clarity and flexibility: 📂 API/Presentation Layer Entry point for all HTTP requests (Controllers) Sends commands/queries to the Application layer Registers DI services in Program.cs / Startup.cs 📂 Application Layer Pure application logic (no infrastructure or UI) Uses CQRS with MediatR Handles DTO mapping, Events, and Custom Exceptions 📂 Domain/Core Layer Contains only business rules and domain models Includes Entities, Interfaces, and Domain Services No EF Core, no HTTP, no UI 📂 Infrastructure Layer Implements persistence, file handling, email, etc. Implements repository/service interfaces from Domain Injected into the Application via Dependency Injection This structure helps me deliver clean, testable, and maintainable solutions—especially in microservices and large enterprise systems. 💬 Have you applied Clean Architecture in your projects? How did it help? #dotnetcore #cleancode #cleanarchitecture #microservices #softwareengineering #csharp #fullstackdeveloper #scalablecode #domainlayer #architecturedesign
