Instead of moving the whole application to the cloud, organizations are building cloud front-end computing elements for existing applications. There are various options regarding the technology to use while executing this approach, including serverless computing and containers. 

The use of web servers that provide online access to applications isn’t a new idea. However, the front-end designed for cloud computing creates a model where the GUI features are hosted on the cloud for scalability and performance improvements, whereas the application back-end can reside anywhere. 

The pressure to modernize – A typical modern application front-end center on an API gateway. This element presents a series of APIs that are invoked from either webpages or mobile applications. Serverless is an architecture for applications that only consumes resources when it executes code, such as these microservices. A microservice and serverless approach makes the front end fully scalable and resilient to failures 

Transactions and events – Users create a transaction through a multistep process. The steps of the transaction correspond to events. The API gateway model suits the serverless implementation. The gateway can invoke the serverless code based on a call from the front-end web server. The front end can also access an online database.

Microservices, serverless, and containers – Major cloud vendors offer a way to easily shift between a serverless deployment of microservices and a container deployment. Microsoft focuses more on microservices deployments, though AWS and Google also enable it.
