Do you know is the major drawback of a monolithic codebase?
There might be multiple modules running in a single codebase. For example:
👉 One module handles your forgot password, change password, login, or registrations—all about user onboarding.
👉 Another module handles creating listings or products, including adding products in bulk/individually, updating catalogs, updating inventory, and updating images—all about managing your product catalog.
👉 Third module handles your cart or checkout process.
👉 Fifth module might handle your payment collection or reconciliation.
👉 Sixth module handles all your communications, such as emails, SMS, or push notifications.
Suppose all these modules are running from a single codebase and different teams are responsible for handling their own module. Now, the cart and checkout team sends a fix in their module with proper testing. They are confident that they haven’t touched other modules’ files, so there is no need to test other modules. They are correct on their end, but because all modules are tightly coupled, their minor changes impacted the communications module, causing all communications to stop working.
The teams were unaware of this. They found out when the customer team started escalating issues about their orders. “What’s happening with my orders?”
How could a simple minor change in the cart and checkout module impact another module, right? But imagine if this change affected the payment module—what would happen then?
This happens every day, not a single day, with organizations that are still using a monolithic system design approach. Their teams waste a lot of time fighting and arguing about whose module or mistake caused the issue. Instead of fixing the issues, they waste most of their time finding out who did it.
If you want to fix this issue permanently, team collaboration alone will not solve it. You might be surprised, but how can we solve this issue permanently?
There is only one solution that will fundamentally fix your problem: you have to migrate your system from a monolithic approach to microservices.
People who have been working on the same codebase for a long time give excuses that this is not possible, it is a major change, it will take a lot of time, etc., and are able to convince their VP or CTO.
But ultimately, you have to migrate your system—if not today, then definitely tomorrow. It will be better for you to make your decision to migrate your system from monolithic to microservices as soon as possible.
