Monolithic architecture is made up of a single huge system with a single code base.
As a monolithic program expands, it becomes more closely connected and entangled, making it impossible to split services for goals such as independent scalability or code maintainability.
Microservices, which were just introduced a few years ago, are now a rapidly growing trend.
The microservices method does, in fact, provide actual advantages such as increased scalability, flexibility, agility, and other key benefits.
Netflix, Google, Amazon, Uber and other software giants have successfully transitioned from monolithic to microservice design.
So is the monolithic architecture method thus obsolete and best abandoned? Is it worth it to convert the entire program to microservices from a monolithic architecture?
In this article, we will be comparing the differences between monolithic and microservices; as well as their benefits and drawbacks, in order to make the best decision for your firm.
MONOLITHIC ARCHITECTURE
The term monolith is derived from an old depiction of a massive rock. Monoliths are enormous blocks of code that include several modules when it comes to software. These modules are inextricably linked to one another.
Because everything is tightly connected and depends on each other, changing technology, language, or framework is exceedingly tough. Therefore, if you wish to alter your code, you must change the complete platform at the same time.
MONOLITHIC ARCHITECTURE PROS
Development is simple: Monolithic architecture is a tried-and-true method that doesn't need any new programming abilities.
Easy to use: Engineers don't have to worry about unloading numerous services bundled via the third-party API because the complete system is uploaded as a single file.
Higher productivity: The absence of a significant number of microservices integrated through the API is thought to make monolithic apps operate quicker. However, a variety of other factors play a role.
Simplified testing: Another benefit of a monolithic structure is that automated tests may be done without having to worry about each service requiring its own testing algorithm.
MONOLITHIC ARCHITECTURE CONS
Tight Coupling: Monolithic applications use tight coupling between service units. Because business logic is intertwined and impossible to disentangle, scalability becomes a problem since only the full program can be scaled, not individual components.
Slow Development and Release: The application's development and testing cycle is slowed since the code base is so large.
Barriers created by new technologies: Applying a new technology to a monolithic program is highly difficult since it necessitates rewriting the entire application.
Speed problems in the future: Deployment and launch times for an application increase as it rises in size.
It's more difficult to make minor modifications: Even minor fixes need redeploying the complete system, which is time consuming.
MICROSERVICES ARCHITECTURE
A monolithic application is a single, cohesive entity, whereas a microservices design divides it into smaller, autonomous components.
As a distinct service, these units handle each application procedure. One microservice may, for example, be used to manage users while another estimates the cost. Each module may be installed and scaled on its own.
Each of these services also has its own database, allowing you to assure service continuity, independence, and data integrity.
By adding a new microservice and modifying the load balancer rules, you may enhance the capabilities of the entire system. It's the equivalent of putting four wheels on a freshly built automobile instead of simply one.
MICROSERVICE PROS
Self-sufficiency: Each microservice can be designed to achieve a specific business purpose while being totally independent of the others.
Technical diversity: With the microservice design, you'll be able to use a different stack for each service which results in increasing efficiency.
Enhanced Organization: The code base is more structured since it is split down into smaller services. The microservices each provide a specific function and are not reliant on other components.
Easy to scale: An application may be expanded horizontally using microservices, which means each microservice can grow in size independently as its needs change. Horizontal scaling is often less expensive than vertical scaling, because there is no limit to how big an app may become.
Easier to understand: Because it is split down into smaller, simpler components, a microservice application may be readily understood and controlled. You can concentrate solely on a service that is relevant to your company's objectives.
Consistent supply: Customers may obtain lasting value due to the autonomy of individual services and modules, and you can always make modifications to certain services without having to shut down the entire system.
MICROSERVICE CONS
Require complicated skills: Building a microservices architecture necessitates specialized expertise that not all developers possess. Teams who create microservices without the proper training may face a variety of issues, resulting in a longer time to market and more expenses to hire outside specialists.
More resources needed: Microservices design necessitates not just more effort but also more development time and labor, which some businesses may not be able to afford.
Longer testing time: Because a microservice design is more complicated, you'll need to engage in more extensive user testing to guarantee that everything is working properly.
MONOLITHIC ARCHITECTURE VS MICROSERVICES - WHAT IS A BETTER FIT YOUR BUSINESS?
In a nutshell, you can choose a monolithic architecture if you have a limited budget and need to create an application that will remain unchanged over time.
Choose a monolith if there are developers who are only familiar with one language and its technology. The best choice in these circumstances is to create a single, integrated system.
Or in the early phases of the life cycle, a monolithic application results in cheaper starting costs and development complexity (one programming language, one repository for everything).
There is no need to use microservices when you have a small technical team working on a basic and lightweight application. Building, changing, deploying, and testing a monolithic application will be a lot easier this way.
For complicated and changing systems, the microservices design is more helpful.
It provides practical methods for managing a complex system of interconnected tasks and services in a single application.
When it comes to platforms that support many user journeys and workflows, microservices are excellent. However, adopting this paradigm would be unfeasible without adequate microservices skills.
