Carlos Alberto Marangon - PeerSpot reviewer
Automate complex workflows with seamless AWS integration
Step Functions provide seamless integration with AWS services, which enhances the speed of application development. The JSON app launched recently allows us to define data execution more easily. The Standard Workflows feature includes error replay capabilities, which are crucial for efficient error management. The Amazon State Language (ASL) in JSON format facilitates workflow automation and accelerates the deployment of Step Functions.
Patrick Norton - PeerSpot reviewer
Support has been among the most helpful and knowledgeable we've ever worked with but performance monitoring needs improvement
The monitoring of the JAMS product and its performance is an area of concern for me. I also need better tools to adopt version seven. Another area for improvement would be the addition of source control for jobs internally, as this feature would solve several problems for me. JAMS has some quirks. It has a bit of a learning curve. Some exceptions are not intuitive, such as when a job is terminated due to exceeding its defined runaway time limit. This generates a misleading exception message that is difficult for new users to understand and requires experience to interpret correctly. Stalled jobs present a unique challenge, particularly when pushing a system like JAMS version six to its limits. While rare, these instances occur when jobs become unresponsive despite appearing in API queries but not in the monitoring console. Although workarounds exist, they highlight the need for improved native monitoring capabilities within JAMS. Currently, the system assumes flawless operation, necessitating supplemental monitoring tools to detect issues like excessive pending or stalled jobs, ensuring timely intervention by our teams.
