The term cloud computing is a technology that uses the internet and central remote server-maintained data and application. Cloud Computing includes data, application and storage and also provides these three basic services i.e. Software as a service, platform as a service and infrastructure as a service. Elasticity is the fundamental attribute of cloud computing. Which will automatically balance the load on the resources provided by the service providers and accordingly divide the cost or reduce the cost for them.Similarly Server-less computing offers powerful, event-driven integrations with numerous cloud services, simple programming, and deployment models, and fine-grained scaling, and cost management. Driven by these benefits, the growing adoption of server-less applications warrants the evaluation of server-less platform quality and the development of new techniques to maximize the technology’s potential. In here the technique of auto scaling and the cost calculation for the auto scaling is discussed in case of cloud services and server-less environments.
