Serverless doesn't mean no servers — it means that developers no longer need to manage the servers themselves. Instead, cloud providers like AWS, Google Cloud, and Azure handle all the provisioning, scaling, patching, and maintenance of servers.
In a serverless model, developers write code in the form of functions or microservices which are then deployed to a platform that executes them only when needed. This is commonly referred to as Function as a Service (FaaS).
Popular serverless platforms include:
With serverless, businesses can focus entirely on the code and user experience, leaving the infrastructure to cloud providers.
One of the biggest advantages of serverless architecture is the pay-as-you-go pricing model. You are charged only for the execution time of your code, not for idle servers.
This helps:
Example: A business in Mumbai with fluctuating user traffic can benefit immensely as serverless scales up during peak hours and down to zero during off-hours.
With serverless, cloud platforms dynamically allocate resources based on incoming traffic. Whether you have 10 users or 10 lakh users, your application will respond efficiently without manual intervention.
Since there is no infrastructure setup, and deployment is as simple as pushing functions to the cloud, developers can build and release features much faster.
Serverless allows developers to:
Serverless eliminates waste by provisioning resources only when the function is called. This ensures optimal performance per rupee spent.
Indian D2C brands use serverless to handle high-traffic events like Diwali or Independence Day sales without worrying about server crashes.
Startups use serverless to build secure APIs that scale automatically — ideal for wallets, loan processing, and KYC services.
Serverless functions help process video uploads, quiz submissions, and real-time notifications on learning platforms.
The result: A significantly reduced attack surface.
A cold start happens when a function takes time to initialize after being idle.
Solutions:
Relying heavily on one provider may reduce flexibility.
Solutions: Use open-source frameworks like Serverless Framework, OpenFaaS, and design APIs to be cloud-agnostic.
FaaS platforms have execution time limits (e.g., 15 mins for AWS Lambda).
Solution: Offload long tasks to background queues like AWS SQS.
India's tech ecosystem is increasingly embracing serverless:
With local data centres and growing cloud adoption, serverless is a strategic direction for Indian businesses.
Serverless is ideal for:
For heavy processes like video rendering or ML training, traditional architecture may be more appropriate.
The serverless revolution is empowering businesses to build faster, smarter, and more efficiently. With reduced costs, simplified operations, and unmatched scalability, serverless is more than a trend — it’s a long-term strategic move.
Whether you're a startup in Chennai or an enterprise in Gurgaon, now is the time to go serverless and gain a competitive edge.
Start small — migrate event-driven functions — and scale confidently with the power of the cloud.
