What is serverless computing?
Sometimes technology comes up with names that make no sense to anyone outside this highly specialised industry. Serverless computing? Does that mean you no longer need servers? Not exactly.
Serverless computing still uses servers, but in new and exciting ways. It opens doors that were previously not even considered, let alone closed.
Serverless computing is available with Microsoft Azure Functions, and adds another acronym to the already familiar ones of Iaas, Paas and Saas. We now have FaaS, standing for Function as a Service.
So while so-called serverless computing still uses cloud servers, those servers can now be called upon only when they’re needed. This means that if your demand for resources dips, so does your cloud resource usage. The cost savings can be considerable when you’re not paying for resources not in use.
How would it benefit your company?
With other cloud-based computing models, you need to decide up front the extent of service resources you’ll need. It’s easy to get this wrong so you end up under- or over-subscribed.
Serverless computing with Microsoft Azure Functions takes the guesswork out of the equation. Server resources are added, adjusted or removed by the vendor depending on demand, so you’re never paying for resources you don’t need.
This makes FaaS infinitely scalable. Regardless of whether you have 100 users one month and 100,000 the next, your resource availability automatically contracts or expands to fit.
Serverless computing allows developers to give all their attention to writing code that gets the job done. They’re freed from the need to make sure the company has the hardware resources to run their application because the vendor manages and plans the capacity behind the scenes. Not only are development costs reduced, apps are ready for market faster
What are the Practical Applications?
Serverless computing is ideally suited to event-driven applications. The most obvious advantages being those associated with Internet of Things applications. Server resources are not used until an event occurs, in which case the appropriate action is taken. This approach leads to better customer service and lower operational costs to the company. It has many practical applications across diverse industry sectors:
- Town and country planning
- Healthcare and medical provision
- Manufacturing
- Gaming and entertainment
- Media
- Transport, both public and private
- Security
- Defence
- Home and property
- Energy and fuel
The list is almost endless, and the adoption of serverless computing is growing at a phenomenal rate. It promises to revolutionise the ways applications in the cloud are developed, built and operated.
