Application and website developers are migrating from monolithic to microservices architecture, well, what can be the explanation for this? In this cloud era, the flexibility in developing applications are reaching beyond the threshold, and this privilege can be in terms of architecture, frameworks or even through hosting services.
Any application which is developed bound to get updated one day or the other. The up gradation process should have a simplified approach; where for the same, the architecture plays an important role. Currently, if we go with monolithic architecture, developers find it very onerous to depend on. Comparisons are bound to happen, so when analyse between these two architectures, the microservices architecture managed to gain more brownie points from the developers.
Monolithic Vs Microservices
Monolithic: A traditional programming model, Monolithic architecture embraces the concept of interdependency. All the elements in this programming model are interconnected, so any updates, then each and every element will have to go an under change. This concept is time-consuming and exhausting for the developers. Suppose the current code structure is revised, then every component of that architecture should be available in order to perform an execution.
Since all the modules under Monolithic architecture will be interrelated, any change to a single module will make the developer to rewrite the whole code. Monolithic is a tightly coupled architecture, where the resiliency required during the development of large-scale applications is not provided.
Microservices: Through this strategic choice developers are able to experience rapid application development process. Not only this architecture is loosely coupled but also simplifies the development process. Three main factors are collaborating in making Microservices architecture more reliable than Monolithic architecture; they are explained in detail in the following section.
- Flexibility– Loosely coupled or decoupled design is the major blinking factor in Microservices architecture. Since the components are not interrelated, the probability of complete application failure is zero in the case of a component failure.Other than this, Microservices architecture is highly stateless, so they can easily maintain the workloads through providing new runtimes.
- Agility & Productivity– Unlike Monolithic architecture, the components here are independent of one another. So any updates to the current application can be performed only to the concerned components. This advantage can reduce the magnitude of code structure, thus minimizing the overall downtime.
- Scalability– Each component of microservice architecture can be scaled independently at run-time. Robust applications require rapid scalability, so each component based on the workload are assigned with resources for rapid development process.
The Bottom Line
Unlike the traditional Monolithic architecture, microservices architecture can be developed in any of the programming language. Also, it simplifies the co-ordination between developers and DevOps team to have an error-free approach. Resiliency is the main factor that one should have while dealing with large-scale applications, which the Microservices architecture is providing unconditionally.
