Top 5 Challenges of Monolithic Architecture

The term "monolithic" signifies "all in one," encapsulating the essence of monolithic architecture— a single, massive, container-like structure that houses all components, intricately interconnected in one place. This architecture reigned supreme in web development, with a whopping 94 percent of developers favoring it for its straightforwardness and speed. However, a significant challenge arose: each time an update was needed, the entire application had to be redeployed. This cumbersome process spurred the shift from monolithic to more efficient, flexible architectures.

Monolithic Architecture Obstacles overcome by Microservices Architecture  

Working with monolith architecture has created numerous roadblocks in the web development process. The pressing need to overcome these challenges has led many to migrate to a more agile and efficient microservices design. Let’s delve into the specific obstacles posed by monolithic architecture and explore how transitioning to microservices can resolve these issues.


Scalability is paramount in today’s tech-driven landscape. The monolithic design, resembling a single, massive container, makes scaling the entire application a daunting task, especially when market demands evolve. Microservices architecture, on the other hand, breaks down applications into independent services. This modular approach allows each service to scale individually, making it more cost-effective and time-efficient. Giants like Netflix, eBay, Spotify, and Amazon have embraced microservices for this very reason, effortlessly scaling up their services to meet market needs.


In a monolithic setup, a server failure can lead to a complete application crash, particularly during peak periods, rendering the system unresponsive. Microservices architecture enhances availability by isolating services. If one service fails, the rest of the application continues to function seamlessly while the faulty service is repaired. This fault isolation and quicker recovery ensure higher uptime and reliability.


Monolithic architecture struggles with performance as applications grow larger. A single server error can compromise the entire system’s performance. Microservices, however, assign separate databases, servers, and resources to each service. This means that a failure in one service does not impact others, thereby maintaining the overall performance of the application. For instance, Etsy faced significant performance issues with their monolithic setup and successfully transitioned to microservices for better performance and platform extensibility.


Monolithic architecture often falls short in terms of infrastructure reliability, struggling with aspects like fault tolerance, failure recovery, and service discovery. Microservices excel in these areas, offering enhanced fault tolerance, easier recovery, and efficient service management. Uber, for example, moved from a monolithic structure to cloud-based microservices, streamlining tasks such as passenger and trip management.

Business Agility

Delivering products through a monolithic architecture can be time-consuming and inflexible, failing to keep pace with market demands. For instance, implementing a custom payment plan within a monolithic codebase is cumbersome due to its large, unified structure. Microservices architecture, however, allows for the independent development and integration of new services, offering flexibility in payment plans and customization according to client needs. This agility ensures that businesses can quickly adapt and innovate based on market and customer demands.

Final note  

In conclusion, while monolithic architecture has its merits, the transition to microservices offers clear advantages in scalability, availability, performance, infrastructure reliability, and business agility. Microservices have proved to be the next step for growing businesses. When deciding whether to use monolithic or microservices architecture, the organization should consider the type of project and the client. By embracing microservices, companies can overcome the limitations of monolithic structures and pave the way for more robust and flexible applications.
