Breaking Monolithic Architecture

Using Microservices to Enhance Performance” 

Microservices architecture is a variant of Service-Oriented Architecture (SOA) where a complex program is divided and developed into many individuals and independent modular services. Each service communicates using a lightweight mechanism. Microservice based architecture enables continuous-delivery and deployment. This type of architectural style is best suited for complex and extensive programs.
Unlike Monolithic architecture, where the application is built as a single unit, microservices provide a more flexible and scalable structure. We used the microservices architecture while building the platform Shortlist.

  Characteristics of Microservices

  • Data-Driven Interface

Each service runs a separate process, this helps in tackling complexities. It is developed using minimum inputs and outputs.
  • Load-Balancing

Microservices can be deployed in the form of various containers making it simpler to handle traffic.
  • Unconstrained Interface

Each microservice have a separate identity, having its unique pre-defined functions.
  • Zero external Dependency

Microservices have their dependencies, so they don’t have to rely on some external dependency. This ensures faster development and deployment of the application.
  • Independent Functionality

Each service in an application handles different function, working together to form a more significant focused role.

  Benefits of using Microservices

  • High Scalability

Since the application is built using multiple microservices which share no dependencies on each other, it becomes easier for the developers to scale the independent service. Each service can be scaled using X-Axis scaling or Z-Axis scaling based upon the need.
  • Simplified and Independent Upgrades

Each service is deployed independently of the other. Single service can be upgraded without affecting or interfering with other services allowing developers to update/change the application in parts.
  • Easier Maintenance and Governance

Codes in microservice architecture are based on only one function and are easy to understand. A small number of codes can be loaded quickly making developers more productive. Since each service runs its own process, it can be monitored and managed efficiently. One can analyse and calculate output from a specific service without interrupting another.
  • Uncomplicated Data Management

Compared to the classic Three-Tier architecture of monolithic software which maintains a central database, microservices are not restrained to maintain a central data repository. The developers are free to use and sustain a database in a way which they seem fit.
  • Polyglotism Development

Microservices have no external implementation dependencies; it can be developed as an individualistic product. A mixture of diverse programming language can be used to create different services. Developers need not rely on a certain one developing language.
  • Continuous Deployment

Microservices are loosely coupled set of multiple services working to form a broader application. This means continuous deployment of services is readily achievable at a faster rate.
  • Fault Isolation

Microservices aids developers to execute fault and resource isolation. For example, suppose in a particular service starts misbehaving or gets corrupted, it will only affect that service. The rest of the services remain unaffected and can function and run even in these conditions – improving the overall integrity of the application.


Microservices provides a flexible and scalable way to develop and deploy an application. Using microservices, one can maintain structural integrity and manage the project efficiently and effectively.
