Abstract:
The adoption of cloud computing for service delivery is a market trend and attracts customers seeking elastic, scalable, and cost-effective infrastructures. Instance-based models, such as Platform-as-a-Service (PaaS), are being used to support mobile applications. Despite the management facilities, the PaaS receives criticism for the inefficient use of resources. Studies point to a new model, known as Function-as-a-Service (FaaS), as an alternative that would offer a more efficient use of resources and lower costs. The present work has proposed to perform a comparative evaluation between FaaS and PaaS service delivery models regarding performance, scalability and costs issues in support of mobile applications based on microservices. The conclusions obtained showed that FaaS presented an equivalent performance, a more efficient scalability and the costs influenced by workload type.
