What are the 3 types of web architecture?
What is web architecture?
Web application architecture is a structure of web application that enables interaction between user applications, middleware systems, and databases on the internet and ensures all these elements are working together. Web applications can be simple functional websites or complex. The user’s request is made to the server through a browser. The browser then executes the request and shows the specific webpage to the user within seconds. Increased internet usage insists applications use web-based communication. So today web architecture is essential to execute the user’s request efficiently. Collaborating with a dependable web development company can optimize the process of creating and deploying resilient web application architectures customized to meet precise business requirements.
The web application has 2 codes.
- Client-side codes (front-end)
- Server-side codes(back-end)
Client-side and Server-side codes where client-side code in the browser is to respond to the user requests and server-side code on the server is to respond to HTTP requests.
3 types of web architecture
1. Monolithic architecture:
This architecture uses one code base in the application to structure a single component providing high performance. It is the best choice for simple programs expecting quick deployment and to perform multiple tasks. However, it could become hard to maintain as it becomes complex and increases in size. This architecture provides operating system services like memory management, process scheduling, and file systems, in a single space. The components within the application interconnect with each other. Thus changes made in one component impact the other areas as well.
Advantages:
- Higher performance as the components are accessed directly.
- A single code base makes development easier. It’s easy to understand as all source code is located in one place.
- Easy deployment
- Simple testing and easy debugging.
Disadvantages:
- Monolithic architecture faces scalability issues. Functionalities within a single code base result in the entire application being scaled as requirements change.
- We need to be more flexible to adapt to the latest technologies and languages.
- A single bug affects the entire system.
2. Microservices Architecture:
Microservices Architecture, also known as microservices, enables the creation of large applications by breaking them down into small, independent services that communicate via APIs. This approach, known as the use of microservices in web development, allows different parts of the application to be made, deployed, and maintained independently, and can be called by other microservices to create a unified response for a single user request.
Advantages:
- Each component can be independently scaled.
- Easy to test and maintain
- Any error that occurs affects only a single service and not the entire system. Thus it's easier to add new features.
- Highly flexible
Disadvantages:
- Independent components are tested separately.
- It is difficult to test all independent elements separately.
- Cross-cutting concerns include configuration externalization, logging, metrics, and health checks.
3. Serverless Architecture:
In this architecture, cloud service providers like Amazon Microsoft, etc. manage the code execution instead of manually deployed on the server. Here multipage applications and services are developed and run without having to manage infrastructure. It's a good option for companies focusing on front-end development tasks and want to entrust server management to any tech partners. Working on small functions in apps is allowed in this architecture.
Advantages:
- Cost is reduced in this architecture as there are no hardware expenses are included.
- In serverless architecture, applications developed can be automatically scaled.
- This is a perfect architecture to quickly deploy an application.
- Users care about the frontend interfaces the most and not the backend codes. The organizations use their time and effort to enhance user experience as the server is managed by third-party service providers.
- Web developers become more productive and efficient as they don’t have to worry about the infrastructure. They could focus on core tasks.
Disadvantages:
- It is a complex process
- Data can be exposed due to misconfiguration of that server as several customers are on the same server.
- Debugging and testing is a complex process as cloud service providers manage the backend process.
- Cold starts happen in serverless architecture as that first function request has some time delay.
