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

"What my team needs are tools to reliably execute all the jobs, minimize the risks, and support high-availability, and JAMS does the job."
"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."
"The fact that we no longer need to use Excel spreadsheets is huge."
"I appreciate JAMS for its readily available templates that allow me to create and deliver stand-up presentations within minutes quickly."
"The key benefits about JAMS is having the ability to run long running jobs on-premise as compared to products like Azure Data Factory."
"JAMS has improved our productivity immensely because everything flows. I don't think we could operate at our current staffing levels without it."
"The built-in triggers are great."
"The feature or capability to import a job is most valuable. We can import an existing job from different platforms, and all the configurations get migrated as well without modifying the code, job schedule, etc."
"I think the possibility to save time developing DAG in a smarter way with Astro by Astronomer is a significant benefit because, as I mentioned before, it suggests the best operator for your use case."
"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."
"Astro by Astronomer has positively impacted my organization by making work easier; tasks are getting completed in much less time than before."
"With Astro by Astronomer, we are paying less than before for MWAA, we are paying for the usage, we can offer Astro by Astronomer usage for other teams which did not have access to our AWS account, and we manage access for them, so it is also a bit easier."
"From a business perspective, we have achieved faster deployments, reduced manual effort, improved reliability, and faster troubleshooting."
"In one year, we save a lot of time using Astro by Astronomer because we do not need to deploy different components of Airflow one by one."
"Astro by Astronomer has positively impacted my organization because I can create more data pipelines to integrate into my medallion architecture, making it easy to do data engineering jobs."
"Using Astro by Astronomer is definitely improving our team's productivity."
"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

"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."
"Fortra is getting much better with documentation and examples, but there is still room for improvement."
"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 UI could be better. There were some things that were not quite intuitive, such as the search tool. When we tried to search for jobs, we had to clear the entire search and then go in and enter the new search query. That's something that wasn't intuitive for a new user."
"The monitoring of the JAMS product and its performance is an area of concern for me."
"If around 5,000 or more jobs run at a time, JAMS slows down, and we have to wait around five to 10 minutes or restart JAMS scheduler services."
"All my machines at work are Macs. JAMS client is a Windows-based thing."
"In terms of improvements, I believe JAMS can enhance its user interface for better user experiences."
"If I had to pick one thing that could be improved, it would be the speed when working in clouds."
"Astro by Astronomer could improve by reducing costs or decreasing infrastructure management and having less dependency on Kubernetes so that the infrastructure is simpler."
"There is room for improvement around having an improved UI and also integration with other tools."
"<p>I think Astro by Astronomer could improve its pricing, as it is really expensive, especially if you want to have large use in a large-scale enterprise edition, which requires you to create a VPC hosted instance that significantly increases expenses.</p>"
"Astro by Astronomer can be improved by adding a full library for dates, working, and interfacing with the diagrams."
"I think that one year ago, Astro by Astronomer needed to improve in reliability because it was a bit slow to develop and sometimes it crashed."
"Astro by Astronomer's CLI might be a little challenging, and having the CLI commands along with the documentation more readily available would be great."
"The documentation part of Astro by Astronomer can be made easier and more generic, not specific to the integration with each of the services."
"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 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."
"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."
"In the end, you'll find that it's really worth the price. There is some sticker shock, but it's worth every dime."
"For what it does, the product is priced very well."
"The product is reasonably priced, and we don't have any add-ons."
"The product is reasonably priced, and we don't have any add-ons."
"It was $10,000 for the first year. Then, there is a maintenance cost for licensing every year that we get billed $5,000 for every year."
"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."
