Serverless computing represents a transformative change in cloud-based infrastructure, but while it is still maturing, it is not a sure fit for everyone.
Let’s take a look at what the technology is, why it’s so revolutionary and whether or not your organisation should adopt a serverless computing model.
What is serverless computing?
Serverless computing is essentially a new environment for programs and applications living in the cloud – the evolution of computing and the newest level of cloud-based deployments.
With serverless computing, you no longer pay for idle time in cloud environments.
Previously, developers needed to play an active role in managing server infrastructure, even if it lived in the cloud. This required building a desired environment within that cloud space, as well as monitoring use activity. In serverless computing, however, those responsibilities are offloaded as the server infrastructure disappears behind the scenes. This lets you focus just on your app, not the tedious upkeep.
A major innovation in serverless computing is its pricing model; in fact, this is one of its most transformative features. Older cloud-based architectures incurred a per-hour cost, requiring you to accurately project use fluctuation and scale infrastructure appropriately. On the other hand, with serverless computing, you only pay for each executed line of code – essentially paying by sub-microsecond intervals. This also eliminates the cost of idle server time.
While more potential applications of serverless computing are still emerging, it is currently being implemented for many use cases, including web-based applications, back-end functions, data processing and chatbots.
When to adopt serverless computing
While this technology is still maturing, it is not meant for every organisation. These are four scenarios where your company can benefit from serverless computing.
- You need a scalable environment.
- You are already using the AWS ecosystem and tools.
- You want to cut costs and reduce the need for server management.
- You are developing a new project or re-architecturing an old one.

In regards to scalability, serverless computing offers far greater flexibility than other cloud-based models – the environment can automatically scale up or down to accommodate surges and lulls in use.
The opportunity in serverless computing is greatest for anyone that has an opportunity to refactor an application stack, but trying to do it for an application or a stack that’s already into a lifecycle is not the way to go. Seeking expert advice can help you determine if this model is right for you.
