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 has improved my organization by taking a myriad of manual processes and allowing us to automate them. It enables our folks to focus more on tasks that require their human intelligence and their creativity and less on just mundane tasks. It increases efficiency, accuracy, and consistency."
"The interface is good, and it's very easy to define and create jobs. If a job is not running or there is an error, the solution will send an email. That's all very good and very useful."
"We also use the solution’s Interactive Agents. If we need to push something to our dealer portal, we can just drop a file in a folder and it goes. Running interactive tasks helps me users focus on business processes since I don’t have to take care of running the jobs manually."
"By using JAMS, my company has seen benefits such as getting to know about Google products and the latest features that are newly launched by Google, and they help me in building my projects portfolio and engaging with knowledge."
"We can see all the batch execution status within the tool itself, which saves money, time, and cost, allowing us to handle everything in one single tool."
"It's a full-featured job scheduling tool. The part that I liked the best was the support team. This tool was new, and we were all learning it and setting up the different jobs that were complex in nature. Their support team was very responsive in helping us out through the setup and resolving the issues. They have been incredibly awesome."
"The most valuable feature of JAMS is its user-friendly interface, especially after upgrading from version six to seven."
"The alerting in it is really targeted... you can set specific alerting so that if jobs in a given folder fail, certain people are alerted. You can also set security at the folder level, so that only people in those areas can go set them. That means that the alerting and security can be set at a very granular level."
"The integration capability is easy, whereas building state machines is tricky."
"The solution is stable...The solution is easy to scale."
"What I like the most about Amazon Step Functions is how easy it is to use."
"The JSON app launched recently allows us to define data execution more easily."
"At the core of our data engineering platform, AWS Step Functions sit at the topmost core of whatever pipelines we have, is a main orchestration tool for us, helps us save costs, and is a key component of our engineering platform."
"It's Amazon, it's scalable."
"AWS Step Functions offers advanced workflows that save time and enhance efficiency by reducing delays and ensuring consistent orchestration among various services."
"AWS Step Functions was stable, and there were no problems that I can recall."
"Flux has made excellent design choices the benefits of which can be passed down to customers in terms of price and capability."
"Excellent customer support"
 

Cons

"The documentation is not super... It's not as quick and slick as I'd like it to be."
"All my machines at work are Macs. JAMS client is a Windows-based thing. It is all built on .NET, which makes perfect sense. However, that means in order for me to access it, I need to connect to a VPN, then log onto one of our Azure VMs in order to access the JAMS client. This is fine, but if for some reason I am unable to do so, it would be nice to be able to have a web-based JAMS client that has all the exact same functionality in it. There are probably a whole bunch of disadvantages that you would get with that as well, but that is definitely something that would make life easier in a few cases."
"The biggest area with room for improvement is the area that my organization benefits the most from using JAMS, and that is in custom execution methods. I happen to have a very good C# developer. Ever since we got JAMS, he has spent a lot of time talking to JAMS developers, researching the JAMS libraries, and creating custom execution methods. He's gotten very good at it. He is now able to create them and maintain them very easily, but that knowledge was hard-won knowledge. It was difficult to come by, and if I should ever lose this developer, then I would be hard-pressed to find anyone who could create JAMS custom execution methods quite as well as he can since there really isn't all that much help, such as documentation or information, available on how to create custom execution methods."
"The tabs in the JAMS file transfer could be clearer. It would help us demonstrate to our client that JAMS not only automates jobs but also does fast transfers, and it's an alternative that supports and filters different kinds of platforms. Filtering file transfers will be highly beneficial to them."
"Right now there's not much of an Azure integration with JAMS at the moment directly because we run separate pipelines."
"As an admin, I would like to have a web-based GUI instead of a client application that we have to install on our PCs."
"I take off a star because of a particular job that I have scheduled for every Monday at 6:00 AM. The setting was unintuitive when it said 'workdays' because it turns out that twice this year it didn't run because Monday was a holiday."
"There could be a better simulation for banning the termination. You have to simulate every one of the processes in order to have an idea for better planning. This kind of simulation is broken and needs improvement."
"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."
"AWS Step Functions' fault tolerance capabilities can be improved, but if managed well in orchestration, then the impact is minimal."
"Setup took about one day. We had some errors to understand in the beginning, but now everything is working good."
"The solution's data size limit can be improved."
"The pricing of the solution can be improved."
"The price and support are areas with shortcomings where the solution needs to improve."
"I think AWS Step Functions is good, but the UI in the console can be much more user-friendly."
"It is hard to coordinate the declaratory language."
"It would be nice to have more file transform capabilities for transforming xml and csv documents."
"Need a better way to track a particular work item through multiple, independent workflows."
 

Pricing and Cost Advice

"The pricing is reasonable."
"The pricing is very fair. We have seen very minimal to no price increases over the years. We are not banging down the door of support all the time either. I would imagine if we were a company that submitted a dozen support tickets a week for the last nine years, then it might be a little different because we would be eating up everybody's time. However, for what we get out of it, the pricing is extremely fair. Back when we were originally looking and brought in JAMS, we were looking at a couple of the other competitive products that were in this space, but the pricing from JAMS was far and away better than what the other competitors could offer for the same functionality."
"Our licensing is pretty cheap because we have a state solution. So, we pay only $1,000 a year."
"The product is reasonably priced, and we don't have any add-ons."
"JAMS is close to the lower end of the pricing models for enterprise scheduling solutions. They are much cheaper than Control-M, as well as some other products that I've used. I also don't know of another solution where you can actually get true, unlimited licensing, where you can have as many instances and as many agents as you want."
"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."
"The product is reasonably priced, and we don't have any add-ons."
"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."
"The solution's price is reasonable."
"The solution is expensive."
