AWS Step Functions' enhanced TestState API now enables local unit testing with mocking support, comprehensive state type validation, and individual state testing capabilities without requiring AWS deployment or IAM permissions.

AWS Step Functions now supports exporting workflows as AWS CloudFormation or AWS Serverless Application Model (SAM) templates directly in the AWS console. This allows for centralized and repeatable provisioning and management of your workflow configurations. AWS Step Functions is a visual workflow service capable of orchestrating virtually any AWS service to automate business processes and data processing workloads. Now, you can export and customize templates from existing workflows to easily provision them in other accounts or jump-start the creation of new workflows. When you combine the Step Functions templates you generate with those from other services, you can provision your entire application using AWS CloudFormation stacks. Additionally, you can export your workflows to the AWS Infrastructure Composer console to take advantage of the visual builder capabilities to create a new serverless application project. Using Infrastructure Composer, you can connect the workflow with other AWS resources and generate the resource configurations in an AWS SAM template. For more information about the AWS Regions where AWS Step Functions is available, see the AWS Region table. You can get started in the AWS console. To learn more, see the AWS Step Functions Developer Guide.

Three weeks ago, I published a post about the new AWS Region in New Zealand (ap-southeast-6). This led to an incredible opportunity to visit New Zealand, where I met passionate builders and presented at several events including Serverless and Platform Engineering meetup, AWS Tools and Programming meetup, AWS Cloud Clubs in Auckland, and AWS Community […]

AWS Step Functions expands its AWS SDK integrations with support for 36 additional AWS services including AWS End User Messaging and Amazon Q Apps, an Amazon Q Business capability. You can leverage our breadth and depth of services in your workflow, without writing additional integration code. AWS Step Functions is a visual workflow service capable of orchestrating over 14,000+ API actions from over 220 AWS services to help customers build distributed applications at scale. By directly invoking AWS services or their API actions from AWS Step Functions, customers can write less code, simplify their architecture, and save costs. In addition to the 36 newly added services, Step Functions also added support for over 1,000 new API actions from new and existing AWS services such as AWS Transfer Family, Amazon EC2, AWS Lambda, and AWS Glue. For the full list of added services, visit AWS SDK service integrations. These enhancements are now generally available in all regions where AWS Step Functions is available. Specific services and API actions are subject to the availability of the target services in the AWS Region. To learn more about AWS SDK integrations, visit the Developer Guide, or build a state machine using our AWS SDK integration tutorial.

AWS Step Functions now supports additional data sources and output options for Distributed Map, enabling more flexible large-scale parallel processing workflows. Distributed map can now process data from JSON Lines (JSONL) and a broader range of delimited file formats stored in Amazon S3. Additionally, distributed map offers new output transformations for greater control over result formatting. https://aws.amazon.com/step-functions/ is a visual workflow service capable of orchestrating over 14,000+ API actions from over 220 AWS services to build distributed applications and data processing workloads. With this update, you can more easily iterate over and process diverse datasets using Step Functions distributed map. In addition to existing JSON and comma separated value (CSV) file support, distributed map now supports JSONL, and new delimited file formats, such as semicolon-delimited files and tab-delimited files. This expands processing capabilities to a wider range of data formats without custom pre-processing. The new flexible output transformations give you more control over how results are formatted, enabling easier aggregation of results and simplifying integration with downstream systems. To get started, you can use the distributed map mode today in the https://console.aws.amazon.com/states/home/ or read this https://aws.amazon.com/blogs/compute/introducing-jsonl-support-with-step-functions-distributed-map/.

AWS Step Functions announces improved observability with a new metrics dashboard, giving you visibility into your workflow operations at both the account and state machine levels. https://aws.amazon.com/step-functions/ is a visual workflow service capable of orchestrating over 14,000+ API actions from over 220 AWS services to build distributed applications and data processing workloads. With this launch, you can now view usage and billing metrics in one dashboard on the AWS Step Functions console. Metrics are available at both account and state-machine level. You can now view these metrics for both standard and express workflows. In addition, existing metrics, such as ApproximateOpenMapRunCount, are available on the metrics dashboard. New dashboard and metrics are available in all AWS Regions where AWS Step Functions is available. To get started, open a dashboard today in the https://console.aws.amazon.com/states/home/.

AWS Step Functions announces support for two new capabilities: Variables and JSONata data transformations. Variables allow developers to assign data in one state and reference it in a subsequent state, simplifying state payload management, reducing the need to pass data through multiple intermediate states. With support for JSONata, an open source query and transformation language, customers can now perform advanced data manipulation and transformation such as date and time formatting, and mathematical operations. Additionally, when using JSONata, we have simplified input and output processing by reducing the number of JSON transformation fields required to call services and pass data to the next state. AWS Step Functions is a visual workflow service capable of orchestrating over 14,000 API actions from over 220 AWS services to build distributed applications and data processing workloads. With support for Variables and JSONata, developers can build distributed serverless applications faster and more efficiently with enhanced payload management capabilities. These features also reduce the need for custom code, lowering costs and reducing the number of state transitions needed to construct and pass data between states. Variables and JSONata are available at no additional cost in: US East (N. Virginia, Ohio), US West (Oregon), Canada (Central), Europe (Ireland and Frankfurt), and Asia Pacific (Tokyo, Seoul, Singapore, and Sydney) with the remaining regions to follow in the coming days. We have also partnered with https://www.localstack.cloud/ and https://www.datadoghq.com/ to ensure that their local emulation and observability experiences are updated to support Variables and JSONata.

AWS Step Functions now supports additional data sources and new observability metrics for Distributed Map. https://aws.amazon.com/step-functions/ is a visual workflow service capable of orchestrating over 14,000+ API actions from over 220 AWS services to build distributed applications and data processing workloads. Distributed Map is a task state of Step Functions that runs the same process for multiple entries in a data set. With this update, Distributed Map now supports additional data inputs, so you can orchestrate large-scale analytics and ETL workflows. You can now process AWS Athena data manifest and Parquet files directly, iterate over S3 objects under a specified prefix using S3ListObjectsV2, read from JSON objects and natively extract array data from JSON object from Amazon S3 or state input, eliminating the need for custom pre-processing. You also now get visibility into your Distributed Map usage with the following metrics, such as Approximate Open Map Runs Count, Open Map Run Limit, and Approximate Map Runs Backlog Size. New input sources and improved observability for Distributed Map are available in all commercial AWS Regions where AWS Step Functions is available. To get started, you can use the Distributed Map mode today in the https://console.aws.amazon.com/states/home/.
