Serverless computing represents a paradigm shift in how applications are built, deployed, and managed. This model allows developers to create and run applications without managing the underlying infrastructure. By offloading server management and capacity planning to cloud providers, developers can focus on writing code that serves business needs. When an application is deployed in a serverless environment, the execution of its code is triggered by specific events, such as a user request or a new data entry.

What is serverless computing and how does it function?

At its core, serverless computing abstracts the server layer away from the application development process. Cloud providers allocate resources dynamically, executing code only when the application needs to perform a function. This event-driven approach eliminates the need for pre-provisioning or scaling servers. The cloud provider quickly spins up a micro-container with the exact resources required to execute the code upon an event trigger, and then the container is discarded once the execution is complete. This ephemeral nature of serverless computing aligns resource usage closely with actual demand.

Benefits of going serverless, including cost savings and operational efficiency

• Cost Savings: With serverless computing, organizations pay only for the compute time used during the execution of the code, rather than for idle server time. This granular billing method results in significant cost savings for applications with variable traffic patterns.
• Operational Efficiency: Serverless architectures streamline operational processes by automating infrastructure management tasks such as patching, scaling, and provisioning. This efficiency allows development teams to commit more time to creating and improving application features.
• Enhanced Scalability: Scaling becomes an inherent feature without manual intervention. As demand increases, the serverless platform automatically adjusts, handling more events in parallel.
• Quicker Time to Market: Developers can bring products and updates to market more swiftly due to the reduced complexity in infrastructure management and the ability to deploy code changes individually.

Organizations across industries can harness serverless computing to unlock new levels of agility in application deployment and management, transitioning resource allocation from a fixed cost to a variable cost directly tied to application usage.
