It means that, with the use of AWS Step Functions, you can build an application within just a few minutes. In case, you are in need of updating the applications, you can easily reorganize or swap the components without code customization.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It also intends to manage resiliency by implementing management concerns upon the state, checkpoints, &amp; restarts to ensure that your application is in the right order of execution. It has potential embedded within itself for dealing with exceptions and errors automatically. It uses the rollback potential and tries or catches retry for automating the error correction aspects.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">AWS Step Functions also takes effort in managing the application logic for the individuals. Along with that, it implements the basic primitives such as parallel execution, timeouts, and branching, that are used for removing additional or repetitive codes within the functions or micro-services.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Application development is faster with AWS Step Functions. It is because the step functions allow you to define &amp; manage the application workflow on independent aspects as compared to the business logic. It means that when you are making changes to one workflow, the other doesn\u2019t get affected.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Moreover, you can easily update or modify workflows in one place. There is no need for any struggle for managing, maintaining, and monitoring multiple integrations from point to point. Step Functions intend to free your containers and functions associated with the excess code, with an intention to speed up the applications for writing and make them resilient and easy to maintain.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Features_of_AWS_Step_Functions\"><\/span><b>Features of AWS Step Functions<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To help you get better clarity on AWS Step Functions, here are some of the features elaborated in this guide to help you understand its efficacy:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Workflow_Configuration\"><\/span><b>1.

With the use of AWS Step Functions, you will get an idea of how each of the steps executed over the workflow interacts with one another. Therefore, you can ensure that each of the steps performs its specified or intended functions.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Branching\"><\/span><b>2. Branching<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Step functions can help make a decision based upon the \u2018Choice\u2019 state input. For instance, if a customer is requesting a credit limit increase, then a \u2018Choice\u2019 state will be created, and the input will help the step functions to process the request. In case, the request is not feasible for approval on the primary end, the step functions can be used for sending the request to higher authorities. But, if the request is acceptable on the primary end, Step Functions will take automatic decisions immediately!<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Parallel_Processing\"><\/span><b>3. Parallel Processing<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The customer can convert a specific video file into several display resolutions, with the use of Step Functions. It is usually done so that the viewers can watch a single video on more than one device. For this use case, a \u2018Parallel\u2019 state is executed that helps the Step Functions input the video file, and process it to work seamlessly in five display resolutions, at a uniform time.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Error_Handling\"><\/span><b>4. Error Handling<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Catch and Retry, are the statements preferable for error handling aspects of AWS Step Functions. The \u2018Retry\u2019 statement, detects and handles errors under instances when a customer requests for a user name, and the request fails for the first time. Under this situation, the \u2018Retry\u2019 statement executes and allows the Step Functions to process the customer\u2019s request one more time. And, the request is processed to be successful during this second time.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u2018Catch\u2019 is also a statement within the same error handling use case. It is triggered when the customers are requesting an unavailable username. With the \u2018catch\u2019 statement triggered, the Step Functions suggest the user with another available username.
