Microservices vs Web Services: Which One of Them Is Better Than the Other?

Microservices and web services are two marvelous architectural styles. Both architectural styles enable a developer to easily develop robust apps in a short amount of time. But which one of them is better than the other? This is the question that we are about to answer today with the help of this post. So, today we are going to compare both the architectural styles and see which one of them is better than the other.

Basic Difference

Microservices is a great architectural structural style that encourages the development of an app as a collection of services. In this architectural style, a single service is responsible for performing only one function in an app. Furthermore, all the services are not dependent upon each other and communicate via API gateways. The architectural style has two main components:

  • Management Component: This component is responsible for managing and configuring microservices. To learn more about the management component, feel free to enroll yourself in the Microservices Course in Gurgaon.
  • API gateway: This component is responsible for controlling the communication between different services.

On the other hand, a web service is a modular application architecture in which all the services of an app are available to other apps via a web interface. The application architecture allows developers to connect monolithic apps and microservices together to form a big app. The application architecture has three main components:

  • SOAP: This component is responsible for controlling communication between apps
  • WSDL: WSDL is responsible for describing web services and the way/process of accessing them.
  • UDDI: This component is responsible for describing/discovering/integrating web services.

Service Specificity

In a microservices architecture, each service is responsible for carrying out a specific task. For example, the messenger app of Facebook has a specific service that is responsible for handling the file attachments of users. On the other hand, in web services application architecture a single web service can offer multiple services from an app. For example, one web service can help an ecommerce app provide order placement and payment services.

Pluggability

Microservices architecture enables developers to easily and quickly add, delete and upgrade services without affecting the entire app. This makes it very easy for the developers to scale up the app and introduce new functions to it. Furthermore, the APIs that link services support both HTTP and HTTPS. On the other hand, updating web services is not that easy and is a very complex task. Furthermore, web services only support HTTP and not HTTPS. Additionally, the components that communicate with web services must also use the same protocol/ message format.

Cost-Effectiveness

In the microservices architectural style, all services are deployed in containers. Since multiple containers can work on the same kernel of the OS the architectural style can help you in saving lots of money. The architectural style climates the need of purchasing multiple OS licenses for running the microservices of an app. This helps its users in saving lots of money and reducing the cost of the development of the app. Furthermore, since APIs are universally connective a developer can easily build a microservices API connection in a very short time. 

Web Services application architecture is also very cost-effective and can help its users save lots of time and money. The application architecture eliminates the need for point-to-point integrations and lots of coding. Thus, it is right to say that both architectures are very cost-effective. Plus, both architectures can help a developer in saving a lot of time too.

Resilience

In both the architectural style, the failure of one service or app doesn’t lead to cascade failure. In both architectural styles, a developer can use the circuit breaker design pattern for detecting and preventing the failure of other services/apps. To learn about the circuit breaker design pattern in more detail feel free to join the Microservices Online Course.

Conclusion

Both microservices and web services are two phenomenal application architectural styles and can provide many benefits to a developer. However, both of them have their own advantages and disadvantages. But overall microservices architecture appears to be a better option than web services architecture. So, make sure you use this architectural style for developing apps rather than using the web service’s architectural style. It is a stupendous architectural style and you won’t regret your decision of using it.
