Functions as a Service
Lambda is a "serverless" system, meaning organisations need not maintain dedicated, always-on infrastructure, such as EC2 instances, to handle traffic spikes.
The benefits to using this framework are in the cost, an operating cost is incurred only when work is done. A complex API structure can be built with API Gatewa, but until data comes in and is processed, there is no fee. This makes it ideal for applications which start small and grow. Costs scale with traffic.
