Real-World Applications:

Serverless computing finds applications across various industries and uses:

  1. Web and Mobile Applications: Serverless architecture is an appropriate pick for the constructing of the web as well as mobile applications which must be built really fast, scaled up and performed at extremely low costs. Developers can use the platforms where serverless architecture is the main feature in platform API development, authentication of the users, content created by the users, as background specially processes, and they have a plenty of opportunity to focusing on working with the servers [14]
  2. IoT and Real-Time Data Processing: Serverless computing is ideal for processing real-time data streams generated by IoT devices or sensors [15]. Developers can use serverless functions to ingest, process, and analyse data in real-time, enabling applications such as real-time analytics, predictive maintenance, and monitoring solutions [16].
  3. Batch Processing and ETL: Serverless architecture is well-suited for batch processing and extract, transform, load (ETL) workflows. Developers can use serverless functions to process large volumes of data, perform data transformations, and load data into target systems, all in a cost-effective and scalable manner.
  4. Event-Driven Applications: Serverless architecture is particularly well-suited for event-driven applications, where actions are triggered by various events, such as user interactions, system events, or external triggers. Developers can use serverless functions to respond to events in real-time, enabling applications such as chatbots, notification systems, and event processing pipelines [17].

Challenges and Considerations in Serverless Computing:

While serverless computing offers numerous benefits, it also presents challenges and considerations that organizations must address:

  1. Cold Start Latency: Serverless platforms may experience cold start latency, where the platform spins up a new container to execute a function in response to an event. This initial latency can impact application performance, especially for latency-sensitive workloads or applications with unpredictable traffic patterns. Edge computing involves processing data closer to the source of generation, reducing the distance data needs to travel and thus minimizing latency. By deploying serverless functions at the edge, organizations can significantly reduce the time it takes to spin up new containers, as the computational resources are located closer to the end-users or data sources. This distributed computing paradigm not only improves application responsiveness but also enhances scalability and reliability by decentralizing processing power. With this organizations can achieve low-latency, high-performance applications that meet the demands of modern, data-driven environments [18].
  2. Vendor Lock-In: This may happen with cloud vendors, such as AWS, Azure and Google Cloud Platform. Organizations should ponder vendor lock-in effects and secure that the portability and interoperability of their applications is no different across different cloud providers. An important issue that was repeatedly raised during cloud computing and technology discussions was the risks linked to dependencies on cloud services and challenges associated with vendor lock-in. On the one side, cloud platforms have the advantage of scale and flexibility they bring, on the other hand these platforms should be used with care as they may lead to excessive dependence on one provider. This dependability of the cloud vendors is a limitation for the organisations to switch between them, which could lead to vendor lock-in. Hence, companies must weigh their cloud strategies and make sure of the portable and interoperable nature of their system across various cloud providers to maintain an agility of their services and avoid the vendor lock-in [19].
  3. Observability and Debugging: Debugging and monitoring serverless applications can be challenging due to the distributed and event-driven nature of the architecture. Organizations must invest in robust observability tools and practices to monitor application performance, diagnose issues, and ensure reliability and uptime.
  4. Security and Compliance: Serverless computing introduces new security considerations, such as securing function execution environments, managing access controls, and protecting sensitive data. Organizations must implement robust security practices and adhere to compliance requirements to mitigate risks and ensure the confidentiality, integrity, and availability of their applications and data. In addition to the points mentioned earlier, recent research has emphasized the importance of security in mobile applications, especially in banking apps. This research highlights the need for strong security measures to protect sensitive user data and transactions, which aligns with the security challenges faced in serverless computing. By learning from studies on mobile app security, organizations can better understand how to secure their serverless environments, ensuring that function execution environments are secure and access controls are tight to protect their applications and data [20].


Serverless computing represents a paradigm shift in how applications are developed, deployed, and managed, offering unparalleled scalability, cost-effectiveness, and developer productivity. By abstracting away the complexities of infrastructure management and providing on-demand scalability, serverless architecture enables organizations to build and deploy applications faster, scale effortlessly, and reduce operational costs. Despite its challenges and considerations, serverless computing presents a compelling opportunity for businesses to innovate faster, respond to changing market demands, and drive digital transformation in the modern era. As organizations continue to embrace serverless architecture, they must carefully consider its implications, adopt best practices, and leverage its transformative capabilities to unlock new opportunities and achieve success in the digital age.
