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.

Unified orchestration has reduced costs and improves governance for complex data workflows
I would say it would be much more helpful if Astro by Astronomer can provide an MCP to use and integrate with Astro by Astronomer and their AI agent Auto, so that we can use our tools like Claude, Code, or Cursor to have a central location where we integrate that MCP in Databricks via the AI gateway, and then we can have a place where we can connect to Astro by Astronomer, Databricks, other tools such as Jira and DataDog, and then have a much more comprehensive analysis and overview and monitoring of the entire data ecosystem. Having an MCP integration would tremendously help us to have a more comprehensive data platform that is more AI-ready. That is one of the features that I can think of. Another thought would be having an integration with Kubernetes instead of just scheduling everything on Astro by Astronomer workers. That would be helpful. One thing I can think of is that the Astro by Astronomer local developer environment can be improved further, but perhaps that is a very niche use case that I have in mind, and it may not be useful for others. There is room for improvement around having an improved UI and also integration with other tools. On governance, I would say we can have a more granular level of governance even inside workspaces. Having much more granular control over people belonging to the same team in Astro by Astronomer could have different access to different DAGs, depending upon our tagging strategy. That is one of the areas I can suggest in terms of improvement. The AI capabilities can be improved further. I would compare the current AI capabilities to newer models provided by Claude such as Opus or Codex.

Quotes from Members

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

Pros

"JAMS gives operations teams a single place to manage, monitor, and track job execution, which from my perspective as a developer improves coordination between teams because everyone has visibility into the status of critical workloads and simplifies troubleshooting since job history, execution status, and other relevant information are all easily accessible, ensuring that business-critical processes are executed consistently and reliably across the organization."
"JAMS Scheduler has indeed helped centralize the management of jobs across all platforms and applications in our department."
"In summary, this product is top class."
"JAMS saves us on the order of thousands of hours per year."
"The user-friendly and adaptable scheduler allows us to manage various scheduling scenarios."
"JAMS positively impacts my organization because it helps make it easier to manage JD Edwards scheduled jobs and fills the gap that the JD Edwards application has with scheduling, resolving a lot of those issues."
"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."
"JAMS Scheduler helps centralize the management of jobs across all platforms and applications, which is very important for our organization because it has improved scalability and reduced costs."
"Astro by Astronomer has positively impacted my organization because it is open source code, so we can use it in AWS, Azure, GCP, or on servers that we have on-premise, ensuring we can use it in every situation."
"If you want a one-stop solution for your orchestration, I think Astro by Astronomer is the best place to look."
"When I say it simplified development and user experience, I mean that it definitely made onboarding easier and reduced time significantly."
"Astro by Astronomer has positively impacted my organization by making work easier; tasks are getting completed in much less time than before."
"Astro by Astronomer has many integrations out of the box, making it easy to use and to access documentation."
"The positive impact of Astro by Astronomer has mainly been on team productivity and the standardization of development."
"Using Astro by Astronomer is definitely improving our team's productivity."
"Astro by Astronomer has positively impacted my organization because it has helped me save time due to the big support and large community, allowing them to help me solve problems that I encounter while working with Astronomer."
"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 UI is completely unintuitive. We had to go and open up a support ticket with JAMS just to get something back."
"I'm not sure if they have fixed it in a newer version, but there is no global search in the version I have. If I have multiple sub-folders that are named for business units, like HR or IT, and I have to search for a job, I cannot search from the top. I have to go to the HR folder to search for a particular job, or to the IT folder."
"Another improvement I suggest for JAMS Scheduler is concerning the JAMS Scheduler desktop client. After prolonged non-use, it just freezes for me, and I cannot even close the scheduler."
"The cost has definitely gone up tremendously. That is where I do know, as much as the feature sets are there, and if the newly acquired company is going to be doing a pushback, they might just say, 'Do we still need to pay this much? Or at that point, should we look into an alternative?'"
"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."
"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."
"When looking at a folder in JAMS with many jobs, it would be good to have better information in the list display of what's inside those jobs. We get some information, but other important details are missing."
"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."
"If I had to pick one thing that could be improved, it would be the speed when working in clouds."
"Astro by Astronomer can be improved always by integrating and being in attention with the capabilities that are emerging in the technology as well."
"I believe there is a need for improvement in Astro by Astronomer, especially regarding the strict limitation of 10 DBT deployments."
"One challenge I find with Astro by Astronomer is the cost because it is relatively higher than other tools."
"One area for improvement is the recent change in the UI with task groups introduced in version two point three and above."
"I think Astro by Astronomer could improve by providing more visibility and webinars about the new features they are releasing for Airflow, as since we migrated to Astro, we have not had the opportunity to fully utilize or have considered that we are not using the latest up-to-date features."
"I think Astro by Astronomer can be improved for newcomers, especially regarding the installation, making it more friendly for Windows users, as we use WSL update."
"Astro by Astronomer is doing great, and while improvement opportunities exist, particularly around the cost model, which can occasionally feel steep, I generally find it quite favorable."
"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

"All licensing models are a little overpriced, but JAMS offers a good value, especially given their support response times and ability to handle unforeseen issues like the SFTP transfers. I hope to find more use cases to get a better bang for our buck."
"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."
"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."
"JAMS is priced competitively compared to similar solutions and offers flexible licensing options to cater to user needs."
"I haven't been involved in the financial side for several years, but we buy one host and unlimited agents, and we get a reasonable price for that. We're happy with the amount we pay and the scalability it provides."
"The pricing of JAMS has not been an issue for us, as it has allowed us to save time."
"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."
