Serverless Architecture

Serverless architecture, despite its name, has revolutionized the way we Tecoreng approach web development. It offers a paradigm shift by abstracting server management and infrastructure concerns from developers, allowing them to focus solely on writing code and delivering value to end-users.

With serverless architecture, developers no longer need to worry about provisioning, scaling, or maintaining servers. Instead, they can leverage cloud-based services that automatically handle these tasks, enabling seamless scalability, cost efficiency, and simplified deployment. 

In this rapidly evolving digital landscape, serverless architecture has emerged as a game-changer, empowering developers to build highly scalable and cost-effective web applications with unparalleled ease.

Contrary to its name, serverless architecture doesn’t mean there are no servers involved; instead, it abstracts away server management and infrastructure concerns from developers. 

By Understanding the fundamentals of serverless architecture, developers can unlock the potential to create highly scalable. Also, agile, and cost-effective web applications.

So, Explore the power of serverless architecture and its impact on web development. Also, we declare the Traditional Server Architecture Process.

How to Work Serverless Architecture and Traditional Architecture?

In this blog post, Technical Core Engineers will explore the traditional server-based architecture and how it differs from the emerging serverless architecture paradigm.

Traditional Server-based Architecture

Serverless Architecture

Traditional server-based architecture has long been the foundation of web application development. In this model, developers are responsible for managing the underlying servers, configuring the infrastructure, and ensuring the availability and scalability of their applications. 

This approach involves upfront costs for hardware, software licenses, and ongoing maintenance expenses. While traditional server-based architecture provides developers with control and flexibility, it also requires substantial time and resources to manage the infrastructure.

Serverless architectures offer simplicity, scalability, and cost efficiency but may have limitations in terms of resource constraints and platform-specific dependencies. 

The serverless architecture uses cloud computing platforms to handle the underlying infrastructure and server management. 

Choosing the appropriate architecture depends on factors such as application requirements, scalability needs, cost considerations, and developer preferences.

Overall, serverless architecture simplifies the development process abstracting away server management and infrastructure concerns. Developers can focus on writing code, while the cloud provider takes care of scaling, resource allocation, and managing the underlying infrastructure, resulting in more efficient and scalable applications.

Serverless Architecture: The Future Of Web Development

The Serverless architecture, also known as Function as a Service (FaaS), is a cloud computing model where the responsibility of managing servers and infrastructure is shift from the developers to the cloud provider. 

In this model, developers write and deploy code in the form of functions, which is execute in a stateless manner in response to events or triggers.

Furthermore, In a serverless architecture, developers no longer need to provision or manage servers, operating systems, or the underlying infrastructure. Moreover allowing them to focus solely on writing application logic. 

Instead, they focus solely on writing code to perform specific tasks or functions. When an event occurs, such as an HTTP request or a database update, the cloud provider automatically scales the necessary resources to execute the function. 

Also, This auto-scaling ensures optimal performance and cost efficiency, as developers are only charged for the actual resources consumed during the execution of their code.

Moreover, This architecture is well-suite for building backend APIs, event-driven applications, and microservices. It allows developers to focus on delivering business value through code, while the cloud provider takes care of infrastructure management. 

By leveraging serverless architecture, developers can create highly scalable, efficient, and cost-effective web applications.

The name “serverless” refers to the abstraction of server management, making it easier for developers to build scalable and cost-efficient applications while reducing the operational overhead associated with traditional server-based architectures.

Benefits Of Serverless Architecture

 Serverless Architecture
-> Reduced Operational Cost

With serverless architecture, developers are relieved from the burden of managing servers, infrastructure provisioning, and maintenance tasks. This allows them to focus more on writing code and delivering business value, rather than dealing with operational complexities.

-> Increased Scalability

Also, Serverless architectures offer automatic scaling capabilities. The cloud provider manages the scaling of computing resources based on the incoming workload. This allows applications to handle spikes in traffic without manual intervention, ensuring optimal performance and improved user experience.

-> Cost Efficiency

Pay-per-use pricing in serverless architectures enables cost efficiency. Developers only pay for the actual resources consumed during function execution, rather than maintaining idle infrastructure. This makes serverless an attractive option, especially for applications with variable workloads, as costs are directly tied to usage.

-> Improved Development Speed

So, These architectures facilitate faster development cycles. Developers can focus on writing code for individual functions, which can be independently developed, tested, and deployed. This modular approach enables rapid development, easier debugging, and faster time-to-market.

-> Increased Flexibility

That provides flexibility by allowing developers to choose the most suitable programming languages, frameworks, and tools for each function. This allows teams to leverage their existing skills and technologies, making it easier to adopt and integrate serverless into existing development workflows.

-> High Scalability and Availability

Serverless platforms handle the automatic scaling and distribution of functions across multiple servers. This enhances the scalability and availability of applications, ensuring they can handle high traffic loads and maintain high levels of service availability.

-> Focus on Business Logic

Serverless architectures enable developers to focus primarily on writing application logic and implementing core business functionality. With server management abstracted away, developers can allocate more time and effort to solving business problems and delivering value to end-users.

Overall, serverless architecture offers numerous benefits including reduced operational cost, increased scalability, cost efficiency, faster development cycles, flexibility in technology choices, improved scalability and availability, and the ability to focus on core business logic. These advantages make serverless an appealing option for modern application development.

Example Of Serverless Architecture 

An example of a serverless architecture for web developers could be a dynamic image resizing service. 

1. Frontend

The front end of the application can be built using HTML, CSS, and JavaScript. It provides an interface for users to upload images and specify desired dimensions.

2. API Gateway

AWS API Gateway can serve as the entry point for the application, handling incoming image resizing requests. It validates and forwards requests to the appropriate backend Lambda function.

3. AWS Lambda Functions

The core of the serverless architecture is the Lambda function responsible for image resizing. When triggered by the API Gateway, the Lambda function retrieves the uploaded image, resizes it based on the provided dimensions, and returns the resized image to the client.

4. Storage 

The uploaded images can be stored in a cloud storage service like AWS S3. The Lambda function retrieves the original image from the storage, performs the resizing, and can store the resized image in a separate S3 bucket or a CDN (Content Delivery Network) for faster access.

5. Authentication and Authorization

To secure the application, an authentication mechanism such as AWS Cognito can be used to authenticate users and authorize their access to the image resizing service.

6. CDN

A CDN can be utilized to cache and deliver the resized images to users more efficiently, reducing latency and improving overall performance.

Monitoring and Logging: To monitor the performance and track any issues, logging and monitoring tools like AWS CloudWatch can be employed to capture and analyze logs, monitor function execution, and set up alarms for critical events.

Serverless Architecture


In conclusion, as serverless architecture becomes more prevalent, it is crucial for web developers to understand its concepts, advantages, and trade-offs. By embracing serverless architecture, developers can leverage its benefits to build modern, scalable, and responsive web applications that meet the demands of today’s dynamic digital landscape.
