Centralized scheduling has improved automation and reduces manual monitoring for complex workflows
The best features JAMS Scheduler offers are centralized job scheduling, dependency management, and monitoring. I also appreciate the alerts and retry options because they help us handle failures without constantly checking jobs manually. Centralized scheduling makes it easier to manage all our jobs from one place instead of maintaining multiple schedulers or scripts. Dependency management is especially useful for chaining workflows because JAMS Scheduler can automatically trigger the next job only when the required previous step completes successfully. Another useful feature is the monitoring and alerting. If a scheduled job fails or runs longer than expected, we can quickly identify it and take action, which is particularly helpful for production support and reducing manual monitoring. JAMS Scheduler has helped quite a bit with identifying common job failures, missed schedules, dependency issues, and execution errors. The alerts and job history make it easier to identify the failure point and take corrective action without manually checking every workflow. JAMS Scheduler's code-driven automation has been useful for handling more complex scheduling logic and workflows that go beyond simple time-based triggers. It is important for us because we can combine scripts, dependencies, conditions, and parameters to support different production scenarios without creating too much manual intervention.

Central orchestration has streamlined complex data workflows and now drives timely aviation alerts
The best features AWS Step Functions offers include the ability to deploy it via code. It helps us orchestrate anything that we want. Even if we have Glue jobs for another use case or Lambda that we are currently looking forward to, we are using Lambda to take DynamoDB data for real-time sales monitoring, then it goes to our S3 bucket. We have multiple workflows that are orchestrated by AWS Step Functions, and at the core, the main functionality is based on different frameworks. We have an Athena complete workflow, Glue job-based workflow, and a separate Lambda-based workflow. All of these are separately handled in AWS Step Functions. This is a good point and again with the inbuilt facilities of it, including how we can construct those workflows and add up a catch state or roll back or do multiple iterations using the Map state, that is very helpful for us.The Map state feature has specifically helped my team create a rollback state of the data since we were dropping some of our data assets. In case we want them back, we just wanted to do this. We took a particular layer and provided the data list, including the tables list, and using the Map state, we iterated over this list and one by one we did the backups of this data at the concurrency of five tables in a single execution. The Catch state, on the other hand, allows us to identify any error immediately. If we encounter an error, the Catch state immediately picks it up and we integrated webhooks or email notifications. That is how we are able to identify immediately if we face any error. At the core of our data engineering platform, AWS Step Functions sit at the topmost core of whatever pipelines we have. It is a main orchestration tool for us and helps us save costs. It is a key component of our engineering platform.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"JAMS saves us on the order of thousands of hours per year."
"Getting JAMS in place was a game changer for us back then."
"JAMS has helped save IT staff time by automating tasks previously performed with scripts, and its scheduling feature has been particularly useful."
"By using JAMS, we have gained a lot more efficiencies in terms of all of those to streamline it, and there is no necessary need for having an overnight engineer just keeping an eye on all of this."
"The fact that we no longer need to use Excel spreadsheets is huge."
"We have over 50 jobs running daily to manage all the integration of our systems and we don’t have to monitor these jobs; they just run, JAMS centralizes the management of jobs in our environment, has streamlined our monitoring, saves us about four hours a week in troubleshooting time, and has helped free up about eight hours a week of IT staff time."
"The built-in triggers are great."
"It has definitely drastically improved our capabilities to scale our automation. Before JAMS, there were a lot of manual processes. We had a couple of operators who spent all day doing that. A lot of the time with human intervention and human processes, it is as good as the person who may be following a procedure and human error is a big problem."
"The integration capability is easy, whereas building state machines is tricky."
"What I like the most about Amazon Step Functions is how easy it is to use."
"It's Amazon, it's scalable."
"The solution is stable...The solution is easy to scale."
"The JSON app launched recently allows us to define data execution more easily."
"Overall, I would rate AWS Step Functions at least nine out of ten."
"AWS Step Functions acts as a high-level layer, allowing us to seamlessly integrate with microservices."
"AWS Step Functions was stable, and there were no problems that I can recall."
"Excellent customer support"
"Flux has made excellent design choices the benefits of which can be passed down to customers in terms of price and capability."
 

Cons

"The client is horrible. Every time JAMS puts out a survey on what they can improve, I always say, "The client: When you are setting up jobs, it is quite horrible." The response has been, "Well, we are just using the Windows foundation," and I am like, "Why isn't it only your product?" We can get around it now that we know its quirks, but it is not the most user-friendly of tools out there. The UI is completely unintuitive. We had to go and open up a support ticket with JAMS just to get something back. It is not user-friendly at all."
"JAMS could be improved with a web client that is accessible and as fast as a normal website, eliminating the need to RDP to the servers to access the JAMS client."
"The search capability needs to be improved because when we try to search for a job, it's hard to do."
"The only thing that they could improve on is the fact that they don't have a browser version of JAMS. They've got all the bits and pieces there if you want to build your own web version of it. It does come with a web client, but it's pretty clunky. They could improve on that."
"In terms of improvements, I believe JAMS can enhance its user interface for better user experiences."
"JAMS handles exceptions fairly well but there are some areas where it might improve a little bit. It has to do with being able to automatically handle exceptions, out-of-the-box, rather than having to code them."
"JAMS doesn't allow us to implement SOC controls. We are a company that trades stocks on the New York Stock Exchange, so all our transactions are audited. It has a feature that saves the file for only a month but doesn't segregate the data between finance and SOC-related compliance."
"If there were a softcover book on how to really take advantage of all of JAMS' tools, I would buy it. I do better with training books than online searching, so a book would be helpful."
"If AWS Step Functions keeps adding more integrations, it would be even better."
"It wasn't easy to understand the licensing model. It's like if you use just a little, it's cheap, but it becomes more expensive as you use more. It's like a hook that ties you inside the Amazon ecosystem. So, it creates a dependency."
"The solution's pricing could be cheaper. It is cheaper than Airflow."
"The solution's data size limit can be improved."
"The interface can sometimes feel limited, as we're unable to see what AWS is running behind the scenes."
"Setup took about one day. We had some errors to understand in the beginning, but now everything is working good."
"It is difficult to suggest improvements at the moment."
"I think AWS Step Functions is good, but the UI in the console can be much more user-friendly."
"Need a better way to track a particular work item through multiple, independent workflows."
"It would be nice to have more file transform capabilities for transforming xml and csv documents."
 

Pricing and Cost Advice

"Our licensing is pretty cheap because we have a state solution. So, we pay only $1,000 a year."
"This is a good product at a fair price."
"The licensing model for JAMS is straightforward and based on the number of agents, not the number of jobs you run. It's cheap and fairly simple."
"There are no additional costs other than the license for Fortra's JAMS which is affordable."
"The pricing of JAMS has not been an issue for us, as it has allowed us to save time."
"Definitely check how many single processes you want to run and count them as jobs. That is how you would work out your pricing on JAMS. For example, if you're running a number of commands and you can put them all into one script and run that script, you can count that as one job."
"Take advantage of its scalability. You can start small. The initial cost is very reasonable. Once you have started picking up the tool and adopting it, then you can scale up from there and buy more agents."
"The product is reasonably priced, and we don't have any add-ons."
"The solution's price is reasonable."
"The solution is expensive."
