Stuart Heriot, Executive Manager – Enterprise Architecture, demystifies serverless technology and looks at the opportunities for financial services.
Since AWS launched the first serverless capability in 2014, it has grown rapidly to form the basis of a new generation of platform services. All major cloud providers are investing in this technology, which promises lower infrastructure costs and flexible scaling through ‘pay by the second’ use.
Serverless tech is not a magic app that runs software without servers. Serverless is about how you pay for the use of the servers; you can opt to pay by the second when you’re actively using the system.
A quick analogy to explain the different options:
Fully Hosted: You buy the car. Full cost upfront. Pay maintenance and upgrade costs.
Cloud Infrastructure: You rent the car. Pay whether you use the car or not.
Cloud Serverless: You use Uber. Pay only when you’re travelling. Driver supplied.
The savings aren’t just about paying only for the time you need it, but also about needing less skills and knowledge to manage the equipment.
Serverless platforms are making it easier for startups and small teams with limited skill sets to deliver scalable applications focusing only on the business problem at hand and not the infrastructure.
Better still, you don’t need to develop your own applications in order to experience the benefits of a serverless solution. In the cloud marketplaces, there are a growing number of ‘as a service’ offerings that charge based on a serverless model.
These can provide Artificial Intelligence and Machine Learning capabilities, database servers or even full application ‘back end as a service’ platforms with integrated APIs and fully managed storage.
Part of the confusion around serverless is whether it’s a one-size-fits-all solution. It has some appealing benefits but it’s not for everyone and for those that could use it, it’s not for everything.
