🚀 Why You Shouldn’t Start with Microservices: A Guide for New Projects

Starting a new project often brings exciting possibilities, and with that, the lure of trending technologies like microservices can be tempting. You may think, "My app will be big someday; I should start with microservices now!" But here’s a reality check: microservices come with complexities that can be unnecessary (and even counterproductive) when you’re just starting out.

Let’s dive into why a monolithic approach may be the smarter, simpler choice when launching a new application. 🧱

❌ Why Microservices Aren't Always the Answer

Microservices, while popular, introduce multiple layers of complexity that aren’t usually essential in the early stages of a project. Here’s what microservices often demand from you and your team:

• 🔄 Team Coordination: Managing multiple services across teams requires extra effort in communication and collaboration, especially as each service likely has its own database and dependencies.
• ⚠️ Failure Management: In microservices, a failure in one service can trigger issues in others, and identifying the source of a problem becomes a much harder task.
• 🕒 Eventual Consistency: Ensuring data consistency across services is more complex in a distributed system than in a single, monolithic database.
• 🤖 Automated Deployments: Each microservice will need its own deployment pipeline, which requires thorough automation and maintenance.
• 📦 Infrastructure Management: A microservices architecture requires additional infrastructure provisioning, which translates to more resources, time, and budget.

👥 Does This Complexity Add Value for Your Users?

In most cases, the answer is no—at least not at the beginning. Users don’t see (or care) whether your backend is a monolith or microservices. They care about features, performance, and a smooth experience. Spending time on microservice architecture before it’s necessary can delay delivering real value to your users.

🏗️ Start with a Monolith

Starting with a monolithic structure allows you to focus on core functionality and user experience rather than architectural complexities. With a monolithic app, you only need a single deployment pipeline, one database, and straightforward troubleshooting, making it easier to test, build, and release features quickly.

⏳ When to Transition to Microservices

If you’re considering moving to microservices eventually, here’s a less risky roadmap:

1. Understand Your Application's Service Boundaries 🧩: As your application grows, you’ll start to notice natural divisions within your codebase, known as bounded contexts. These are the areas where splitting into separate services could bring efficiency.

2. Evaluate Your Team’s Readiness 👥: Microservices demand technical expertise in managing distributed systems. If your team has minimal experience in microservices, sticking with a monolithic structure will help them focus on building the core application.

3. Identify Real Needs 📈: If your app begins to face challenges—such as scaling specific functions independently or handling increasingly complex workflows—then consider gradually transitioning to microservices.

🌱 Keep It Simple and Grow with Intention

Starting with a monolith doesn’t mean you’re stuck with it forever. It allows you to build a stable foundation, discover your service boundaries, and scale your architecture as real needs arise.
