Amazon Web Services Step Function allows the developer to visualize and manage the multi-component applications and the components of distributed. The multi-component and distributed applications that consist of microservices offer many benefits such as the ability to eradicate widespread application failure when the error emerges, flexibility to make changes and update to the software component without any need to modify the entire application and improved scalability.
AWS Steps Functions simplifies the interaction between the microservices which makes easy to manage. This service consists of a graphical interface that will allow the developers to visualize and map out the application components which is also known as functions where a number of steps called a state machine. This will allow the developer to change, coordinate and add the application workflow components without the code.
AWS Step Functions cam triggers each step automatically which can be time-based, sequential, branching and parallel. A step can also represent a work, unit or task. It tracks each step in real time basis which enables retries in the case of the logs and failure executive errors and history. The service will trigger the task through the step functions application programming interface which can be carried out by resources such as Amazon CloudWatch Event, Container or Local server, AWS Lambda function and Elastic Compute Cloud Instance. AWS Step Function will be helpful for Serverless applications where it visualizes the interaction between the AWS Lambda functions to make it easier to manage.
