Microservices: Did We Make Software More Complex Than It Needed to Be?

Syed Abdul Khader — Mon, 24 Aug 2026 12:43:48 +0000

A few years ago, microservices became the default answer to scalability and modernization.

Need to scale? → Microservices.
Need independent deployments? → Microservices.
Need better maintainability? → Microservices.

But there is a question we don't ask often enough:

Did we sometimes introduce microservices where they weren't actually needed?

A simple application that once had:

1 application → 1 database → 1 deployment

can eventually become:

10+ services → multiple databases → API gateways → service discovery → message brokers → distributed tracing → centralized logging → container orchestration → CI/CD pipelines

And suddenly, a simple business transaction becomes a distributed transaction.

The hidden complexity of microservices

Microservices can introduce challenges such as:

🔹 Network latency and failures
🔹 Distributed transactions
🔹 Data consistency issues
🔹 Service-to-service authentication
🔹 Complex debugging
🔹 Deployment and infrastructure overhead
🔹 Version compatibility between services
🔹 Monitoring and distributed tracing
🔹 Increased operational costs

None of these mean microservices are bad.

They simply mean microservices are a trade-off, not a free upgrade.

So when do microservices make sense?

They can be a great choice when you genuinely need:

✅ Independent scaling
✅ Independent deployment
✅ Clear business/domain boundaries
✅ Multiple teams working independently
✅ Different technology or runtime requirements
✅ Strong isolation between capabilities

But if the application is small, the team is small, and the domain boundaries aren't clear, a modular monolith might be a better starting point.

You can still maintain clear modules:

                    Application
                         |
        +----------------+----------------+
        |                |                |
     Orders           Payments          Users
        |                |                |
        +----------------+----------------+
                         |
                      Database

And later, when there is a real reason to split a module, it can evolve into a service:

                 API Gateway
                      |
        +-------------+-------------+
        |             |             |
     Orders       Payments        Users
     Service      Service         Service
        |             |             |
       DB            DB            DB

The real architectural question

Instead of asking:

"Should we use microservices?"

we should ask:

"What problem are we trying to solve, and is microservices the simplest solution to that problem?"

Good architecture isn't about using more technologies.

It's about choosing the right level of complexity for the problem you're solving.

Sometimes that means microservices.

Sometimes it means a modular monolith.

And sometimes, a simple monolith is exactly what you need.

What do you think?

If you were starting a new application today, would you choose:

Monolith 🏠
Modular Monolith 🧩
Microservices 🚀

And most importantly — why?

I'd love to hear what has worked (or failed) in your real-world projects.

From Developer to Architect — What Really Changes?

Syed Abdul Khader — Mon, 24 Aug 2026 12:21:06 +0000

One of the biggest transitions in a software engineer’s career is moving from “How do I implement this?” to “How should we design this?”

As developers, we naturally focus on writing clean code, implementing features, fixing bugs, and improving performance.

But as you move toward an architect role, the questions become different:

🔹 Scalability — Will this solution work when the number of users or transactions increases 10x?

🔹 Maintainability — Can another team understand and extend this solution two years from now?

🔹 Security — Are authentication, authorization, data protection, and secrets management considered from the beginning?

🔹 Performance — Where could bottlenecks occur, and how can we identify them before they become production issues?

🔹 Resilience — What happens when a dependent service goes down?

🔹 Integration — How will this solution interact with existing enterprise systems?

🔹 Technology choices — Does the technology solve the actual business problem, or are we choosing it simply because it is popular?

🔹 Trade-offs — What are we gaining, and what are we giving up with each architectural decision?

A senior developer asks:

“How can I build this feature?”

An architect asks:

“What is the right solution for the business, technical, operational, and long-term requirements?”

The most important lesson I’ve learned is that architecture is not about creating complicated diagrams or using more technologies.

Good architecture is about making the right decisions at the right level, understanding trade-offs, and creating solutions that can evolve with the business.

And you don't suddenly become an architect because of a designation.

You gradually become one by thinking beyond your code.
