When Should You Consider Microservice Architecture?

Microservices are a hot trend in modern software development — but they’re not always the right choice. If you’re building a new application or scaling an existing one, you might wonder: “Should I go with microservices or stick to monolith?”

In this short article, let’s explore when microservice architecture is a good fit, what the ideal use cases look like, and when to avoid it.

Let’s dive into the topic:

🚀 Quick Intro: What Is Microservice Architecture?

Microservices is an architectural style where an application is broken into smaller, independent services, each focused on a specific business function.

Each microservice:

• Has its own database or data source
• Runs independently
• Communicates with other services via APIs
• Can be developed, deployed, and scaled separately

Examples of microservices: authentication service, product service, payment service, etc.

✅ When Should You Consider Microservices?

Let’s look at real scenarios where microservices shine 🌟

🔹 1. When Your Application is Growing Rapidly

If your application is getting larger and harder to manage, splitting it into smaller, independent services makes it easier to:

• Develop
• Deploy
• Scale
• Maintain

✅ Example: An e-commerce platform with growing modules like product catalog, payments, orders, inventory, etc.

🔹 2. When You Have Multiple Teams Working on Different Features

Microservices allow different teams to own different services, enabling them to:

• Work independently
• Choose their tech stack
• Deploy at their own pace

Different microservices can be written in different languages and use different databases.
