This becomes particularly critical when applications require fast response times. Cold starts and the resulting latency times are challenges that need to be understood and taken into account when designing serverless systems.

We address these and other specifics of serverless computing to realize its full potential, while looking for ways to successfully overcome these challenges.

Cloud backend models: BaaS, FaaS, PaaS compared

When comparing cloud services, we come across three central Cloud backend modelsthat characterize the development and provision of applications: Backend as a Service (BaaS), Function as a Service (FaaS) and Platform as a Service (PaaS). Each of these models offers specific advantages and is suitable for different scenarios within software development.

BaaS is a model in which server-side software components are outsourced and managed by a third-party provider. This allows us to focus on front-end development, as many back-end processes such as database management, user authentication and push notifications are already standardized and operational.

FaaS allows us to execute code in the form of individual functions that only become active when needed and shut down again when they are not required. This event-driven and completely serverless model offers us dynamic scaling and billing exactly according to consumption, which ensures a high level of performance. Cost efficiency makes it possible.

PaaS provides a complete development environment in the cloud that allows us to develop, test and deploy applications over the Internet. This includes hardware, operating systems, storage and networking capabilities as well as developer tools, database management systems and more, covering the entire development lifecycle.

Model	Target group	Characteristics	Usage scenarios
BaaS	Frontend developer	Outsourced backend services	Apps with standardized backend
FaaS	Developer of dynamic solutions	Event-driven code execution	Microservices, event-based applications
PaaS	Holistic development teams	Complete development environment	End-to-end application development

By using the Comparison of cloud services we realize that these models do not compete with each other, but are designed to complement each other. For specific project requirements, several of these models can even be combined to create the optimum cloud infrastructure. This gives us enormous flexibility and allows us to deploy our resources and expertise efficiently.
