Serverless Computing, in the context of modern software development and cloud-based infrastructure, refers to an architectural approach that allows developers to build and run applications without the need to explicitly manage, provision, or maintain servers. This paradigm shift is made possible due to the outsourcing of server management and resource allocation tasks to backend cloud service providers, such as Amazon Web Services (AWS) Lambda, Google Cloud Functions, and Azure Functions. As a result, developers can now focus on writing code that encapsulates business logic and functionality, rather than grappling with the complexities and challenges associated with server administration.
From a cost perspective, serverless computing enables organizations to optimize resource usage and save on operational expenses, as they are billed based on the actual execution time of their application code, rather than pre-configured or fixed server capacity. This on-demand pricing model provides significant financial benefits, particularly for event-driven applications that experience sporadic or unpredictable workloads, as it pertains to both resource utilization and scalability. In fact, according to a 2019 report by Gartner, the public cloud services market had reached $282.3 billion, with serverless computing billed as one of the fastest growing segments within this market space.
Contrary to its name, serverless computing does not imply the absence of servers, but rather alludes to the abstracting away of servers from the purview of developers. The cloud service provider automatically manages the provisioning of underlying server resources, which are often run within containerized environments like Docker or Kubernetes. As a result, developers are not required to engage in tasks related to managing server configurations, patching operating systems, or monitoring, scaling, and fault-tolerant capabilities of server infrastructure.
Serverless computing functions through the use of Function as a Service (FaaS), a cloud service model that enables developers to deploy single or multiple granular pieces of code that are executed in response to events or triggers. These event-driven functions are typically small, stateless, and specialized, thereby facilitating a faster time-to-market, increased code reusability, and simplified management of distributed applications. Moreover, FaaS offerings can generally support a wide range of programming languages, such as Python, Go, Node.js, and Java, to cater to the diverse skill sets of developers and software engineering teams.
An example of a popular serverless computing use case is image processing, where an event-driven function is triggered whenever a new image is uploaded to an object storage service like Amazon S3. The function subsequently processes the image, compresses its size, and saves a thumbnail to a database. This process is highly scalable as it automatically executes upon each image upload, enabling concurrent and efficient processing of a large number of images.
