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.

A continuously evolving, stable solution, with responsive support
The visual whiteboard for design and execution included with the solution is very crucial to those who are new to Rocket Zena, especially so that the learning curve is minimized and they can focus on accomplishing the task. We process our system's payroll through Rocket Zena. The fact that it's a multi-process, multi-layered application, means that we can rely on the solution for kicking off processes, notifying user vendors of the steps, completions, error logging, and historic events from the previous run times. Rocket Zena's ability to automate jobs on the mainframe as a distribution workload automation solution is good. The solution continuously improves over time. We're eager to start the latest upgrade this coming year that'll put us on the cloud. Hopefully, this will improve the product even more. We can run things natively without the scheduler if needed. The solution working properly and up to date without the need for a mainframe scheduler is crucial. We use the solution to manage a few complex operational workflows end-to-end across multiple technology stacks. Rocket Zena does a great job of simplifying our cross-platform processes through automation. The solution helps speed operations up and keeps them automated allowing us to focus on other priorities. The solution helps increase our completion rates by working overnight to meet our SLAs. Rocket Zena completes 30 percent of our workload outside of our standard work hours. Rocket Zena's cross-platform job scheduling helped us save around 40 percent of programming time by automating repetitive tasks. We use the solution to transfer our current files and keep up with our infrastructure on a few automated jobs, such as refreshing our database which happens overnight. The solution helped free up around 15 percent of our engineer's time to focus on more value-added work.

Quotes from Members

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

Pros

"Getting JAMS in place was a game changer for us back then."
"JAMS has been a beneficial monitoring tool for our project in terms of being able to deliver data that is essential for users."
"The most valuable feature for us is that it's DR-ready. With respect to disaster recovery, it has the built-in capability for failover to our DR site. If all of the required ports are open, it can be done seamlessly."
"The dashboard is intuitive."
"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."
"JAMS has improved our productivity immensely because everything flows. I don't think we could operate at our current staffing levels without it."
"JAMS is easier to use and cheaper than our previous solution. The installation is more straightforward, and JAMS has a graphical user interface, so it's more accessible."
"Our company is based on data. Everything we do is data-driven, so it has been very valuable having one place where we can process all of the data and do batch schedules with chunks of data."
"The return on investment has been remarkable, with savings exceeding seventy-five percent compared to previous manual cron job management."
"It is mainly an improved version of Apache Airflow, and it has improved everything from the open source Airflow."
"Astro by Astronomer has impacted my organization positively because all the automation that was done manually before is now automated and gives us more time to analyze and concentrate on important business matters."
"The best features Astro by Astronomer offers include a large operator and library that I can work with for different use cases."
"Astro by Astronomer has positively impacted my organization because it continuously follows the latest version of Airflow as an open-source project."
"The positive impact of Astro by Astronomer has mainly been on team productivity and the standardization of development."
"Astro by Astronomer has many integrations out of the box, making it easy to use and to access documentation."
"Astro by Astronomer has positively impacted my organization by automating ingestion pipelines, transformations, and error handling, and it has given us relief."
"You can click Ctrl-G and bring a diagram view. You're able to view in a diagram format. The view that it provides is easy, and you can move to the left, up, or down. You can double-click on a certain process. It'll drill into that process and all of its underlying components. You can double-click on an arrow or a component, and it'll bring up a screen that'll have all the variables that are assigned to that particular piece, as well as the values at run time. So, the diagram feature of it, at least for me, is pretty valuable."
"In the latest upgrade, Zena added a web-based client. The more I use it, the more I like it. It's an excellent interface. They do a good job of steadily improving the solution to make it more useful."
"Once you master it, it's a pretty good tool."
"Its FTP feature is very good, as is scheduling any process or task with the Zena client. I have found it to be very helpful. If a task fails, it gives you a prompt."
"We haven't had any problems since we installed it. It runs as expected, we haven't had any critical problems. It helps keeps the business running 24/7."
"I have found the scheduling feature the most valuable, as I can map dependencies by using ASG-Zena and it gives a nice, quick visualization as to where things are."
"From a Linux configuration point of view, Rocket Zena is straightforward. It's fairly easy to set up the server and agents once you know how to do it."
"I like the whole product, but specifically, I like the license part. It's very easy to acquire a license for this product."
 

Cons

"I would like a simple web interface that I could give to my team to go in and kill jobs or see why jobs died so that we don't have to drill down deeper into the application and know everything about it. It would be good to have a really clean web engine that would say here are the jobs running. We can then click to see the time running and whether any of them fails and other similar things. I know they have one, but it's not very simplistic."
"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."
"The UI is completely unintuitive. We had to go and open up a support ticket with JAMS just to get something back."
"One area for improvement would be making the user interface more intuitive, especially for new users working with complex job dependencies."
"They recently switched to subscription-based pricing, which increased."
"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."
"The monitoring of the JAMS product and its performance is an area of concern for me."
"To improve JAMS, it should resolve the issues with the JD Edwards application and the need for the SSH agent in the current version, which has been a problem for a while."
"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."
"I believe one area for improvement for Astro by Astronomer would be to further expand the documentation and examples for more advanced scenarios, especially involving integrations with AWS, Amazon ECS, AWS Fargate, and Astronomer Cosmos."
"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."
"Astro by Astronomer could improve by reducing costs or decreasing infrastructure management and having less dependency on Kubernetes so that the infrastructure is simpler."
"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."
"I would like to add that the pricing could be improved."
"Astro by Astronomer can be improved by adding a full library for dates, working, and interfacing with the diagrams."
"I believe there is a need for improvement in Astro by Astronomer, especially regarding the strict limitation of 10 DBT deployments."
"Rocket Zena is a mainframe-based job scheduler. I would like it to be more open so that we can use it on a distributed platform."
"The scheduling mapping is a little disjointed. There is no wizard-type approach. There are a lot of different things that you have to do in completely different areas. They could probably add the functionality for creating all components of a mapping or an OPA schedule. The component creation could be done collectively rather than through individual components."
"In the next release, I would like the user experience to be improved. The user interface should be more appealing to gen-z."
"The UI is not intuitive, and it would be nice if there was a web interface."
"Another one that is probably a little bit bigger for me is that when there is an issue or there's an error, it writes on a different screen. I have to find the actual process name and go to a different screen to view the alert that got generated. On that screen, everyone's processes, not just the processes of the folks in my department, are thrown. It takes me a while to find the actual error so that I could go in there and look at the alert. It could be because of the way it was set up, but at least for me, it isn't too intuitive."
"The scheduling mapping is a little disjointed. There is no wizard-type approach."
"In the web interface, it stacks the tasks across the top, and they accumulate until you close or clean those out. That seems a little cumbersome. You must right-click and close all tabs constantly to keep the console clean and manage your views."
"Another one that is probably a little bit bigger for me is that when there is an issue or there's an error, it writes on a different screen."
 

Pricing and Cost Advice

"It's certainly a lot cheaper than Tivoli and Control-M. In comparison to them, you get a lot more bang for your buck. You get pretty much the whole functionality and more, in some cases, when compared to Control-M, but at a fraction of the 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 product is reasonably priced, and we don't have any add-ons."
"JAMS is relatively inexpensive, with additional costs only incurred for tags, other services, and optional support renewals."
"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."
"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 reasonable."
