Which is the best; Amazon ECS or AWS Lambda ?

Amazon EC2 is a container technology as pay-as-you-go basis. Amazon Web Services Lambda is a serverless computing or function as-a-service with the ability to access specific functions such as pay-as-you-go terms. They both serve the same objective by providing a computing environment for services, micro services and applications that allow developers to focus on the application and not on the infrastructure. They provide similar service but they still differ with the services that they provide. It is better to buy the service which is best suited for your application which can provide maximum scalability and high-performance responsive website or application.
