Serverless – A Developer Perspective

Serverless technologies are changing application development and deployment, making it easy for developers to take their idea to market fast and at a lower cost. This combination of agility and low costs leads to experimentation, leading to rapid innovation. With serverless technologies offering robust cloud-based IDE, SDK, and frameworks, developers have robust tools and frameworks at their disposal to address specific needs in development, testing, debugging, and deployment. Developers can gain immensely using serverless technologies for app development, greatly enhancing their productivity.

Developer Advantage with Serverless

From enhanced scalability to greater flexibility, reduced liability, innovation, and many more, serverless architectures offer the developer a wide range of benefits, all at a reduced cost and a quicker time to market. In this section, let us consider some of the benefits:

  • Fosters innovation: Applications hosted in a serverless environments are usually broken up into smaller functions and the abstraction adds many constraints. As developers are forced to face the challenges imposed by such constraints, they are expected to change their development process. With time, all these challenges foster innovation as developers adopt a wide range of strategies to deliver functional apps. When the Serverless abstractions are used along with modern technologies like machine learning service for text analysis or image recognition, innovations accelerate. The abstraction provided by Serverless along with the constraints leads to rapid innovation, meeting the business needs of today’s globalized economy
  • Advanced coding: Higher-level programming abstractions offered to developers by some serverless frameworks can advance their coding skills. From function packaging to advanced sequencing and composition, you take your coding skills to the next level by exploiting these programming abstractions to construct highly complex serverless apps easily.
  • Seamless Upgrades: Apps developed for the serverless environment are collections of functions instead of single monolithic stacks. This means that developers have the option of uploading all their code at once or a single function at a time without having to manage servers and the stacks on top of operating system. With this advantage, developers can update, patch, or add new features by changing one function at a time instead of reworking the entire app. This accelerates applications updates and upgrades and makes it easy to upgrade without any downtime.
  • Enhanced scalability: Serverless architectures are highly scalable, which means that developers can code without worrying about growth or the number of concurrent requests. During coding, developers can exploit seamless scaling features of such services by taking advantage of stateless application architectures. This allows for seamless scaling without having to wait for servers to be provisioned
  • Greater flexibility: With the tools like browser based IDEs, SDK and API access, developers get more flexibility in their application development and deployment. With Microservices architecture becoming the norm, Serverless technologies are helping developers build applications using modular architectures.
  • Event driven apps: Since Functions as a Service model uses Action and Trigger as the two major primitives, newer programming paradigms that invoke Actions asynchronously, directly via REST API, is available for developers. Developers can benefit from executing event requests using a variety of sources to trigger parallel invocations or sequential invocations. This opens up new vistas for developers, helping them innovate much rapidly than in the past.
  • Zero system administration: With zero system administration, developers using Serverless technologies are free to adopt creative and novel coding strategies to expand their apps without worrying about server capacity constraints or the operational burden that comes with managing the underlying infrastructure stack.

With the developer advantage offered by serverless technologies, it is easy to see why serverless computing is growing rapidly in popularity.


Even though Serverless technologies offers many benefits to developers, it also puts some limits on the type of applications that can be deployed using these technologies. Developers should be mindful of this limitation while planning their deployment stack,
