Introduction to serverless computing
Serverless computing is useful for developers to build and deploy applications without having the risk of managing infrastructure. In the serverless environment, the provider takes scaling and provisioning to run the application code. In this case, developers concentrate on writing the logic without worrying about any server configuration and hardware. The system is cloud computing model where resources are allocated to various tasks (Selvarajan, Chinta, & Reddy, 2023). No need to allocate the resources, but it updates on the necessities, which allows developers to deploy the application without any server management. The serverless computing does not only mean there are no servers used instead; it means there is a server management hidden and used at the back end.

Benefits of serverless computing
Improved observability through application decomposition
The major advantage of the serverless computing model is the breaking down of the application into modular components. The approach helps in specific tasks to provide independently. In applications that are divided into micro and small-sized parts, it becomes easier to monitor and understand each performance. The system enhances the visibility of the entire system and helps the developers troubleshoot the early issues. Moreover, developers gain a deep understanding without the need to grasp the entire application. The system consequently leads to faster code maintenance and an increase in development efficiency.
Event-driven architecture
Serverless computing operates an event-driven model rather than a continuous stream of data. In the structure, it facilitates the triggering of events such as API call, action of user, and change of data. The model benefits the functions and supports the applications. This is a major difference from a traditional model, which is linked to the failure of one service to another service. The driven approach helps in improving the fault tolerance and resilience.
Rapid deployment and greater agility
One of the major aspects of serverless computing is the quick development process. Since there is no need to maintain the services, developers see the launch of the applications without taking much time. The approach automatically adjusts to handle the workload without any manual intervention. The model is especially a fast-changing environment to facilitate the business process.
Cost efficiency
Serverless computing leads to cost savings. Since the infrastructure maintenance is handled by the cloud provider, organizations no longer need to invest in database and hardware systems. These costs are aligned with data management and computing power. With this, the company’s focuses towards direct impact of innovation and growth.
Enhancing user experience
Most of the applications are for digital experience. When it comes to infrastructure maintenance, the energy is improves the overall customer experience and user interface (Belhe, Barshikar, & Kadu, 2023). The serverless computing focuses more on prioritizing the design. the features are helpful to benefit the users and improve user satisfaction.

Use cases of serverless computing
Real-time data handling
The serverless computing is especially suitable for situations for handling the immediate response and analysis. The Internet of Things is the best example of sensor-generated data and analysis of actions. The serverless architecture automates the data and handle the large volume of data. For example, a smart city utilizes serverless functions to manage the sensors in traffic and adjust the traffic lights according to the traffic to reduce congestion.
Web applications and API back ends
Serverless architecture helps the developers to dedicate their efforts towards building applications instead of managing back-end infrastructure. The system concentrates on developing the applications (Borade, 2024). For instance, an online store that has a serverless setup ensures automatic searches in promotional events. The teams don’t need to worry about the server capacity, but it depends upon improving the user experience by enhancing the new functionalities.
Media file processing
The tasks that demand heavy computing resources, such as the processing of videos and images, benefit from the elasticity of serverless solutions. For example, there is a social media platform where users upload media and content. The serverless functions trigger to automate operations like compressing the files and converting the images to upload. Helps an efficient process without the need for reserve resources and occurs instantly.
Challenges of serverless computing
Cold start delays
One of the major issues of serverless computing is the cold start problem. When the function is not used for a while, there is a delay as a cloud provider initializes it (Codingmart Technologies, 2024). The system impacts the user experience in responding to the events. Developers use methods such as various functions to streamline the code. Various helpful tools, such as Epsagon and Dashbird, to help the start events.
Troubleshooting and visibility
The serverless systems inherit distributed methods, which are less effective. These operate independently with various services. Maintaining visibility is a major task to implement monitoring the failures and tracking the performance. The various tools, such as Google Cloud Trace and Azure Application Insights, which help observe the features and improve the debugging.
Security responsibility
The infrastructure layer is managed with a cloud provider, and developers are responsible for securing the application code. The system helps in the implementation of strong authentication and data encryption (Dutta & J, 2024). There are serverless applications that use third-party packages. By following the standard measures, automates the applications and safeguards the serverless applications.
Conclusion
Serverless computing has reshaped cloud technology by offering flexible and efficient services to build and run the applications. The model has promoted developers to the easy way of delivery to the users and emphasizes the empowering of organizations. The event-driven model offers various benefits such as monitoring and updating the streamline services. In conclusion, The system adapts to various technologies in real-time processing and media handling. Despite many challenges, serverless computing has issues such as complex debugging, vendor locking, and cold start latency issues. All these have a solution and rules for observing and maintaining the services. The digital transformation enhances rapid deployment and shifts toward enhanced demands.
