Automation has replaced nightly monitoring and delivers reliable, unified job scheduling
We have really enjoyed working with JAMS in terms of notifications, alerts, and streamlining. There used to be a process with Automate, which is another product from Fortra, but even before that, the other division of the company that we were merging with had a tool that was built in-house called a file handler or file distributor. It was an in-house developed tool, but it was not as streamlined or as efficient as JAMS is. We literally had to have a dedicated nighttime person monitoring. Although we are 24/7, the divisions of the company that we were using JAMS for have been small scale. While we have automated it, we have streamlined it in such a way that notifications go out and alerts go out, but if there is anything, then we get paged and alerted, and if anything needs to happen at midnight, we can wake up. On the other hand, with the tool I mentioned, the file handler and distributor, we used to have a dedicated nighttime person that had to be sitting and monitoring it to see when a file arrived, whether it met the conditions, and then execute the next particular job. 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.

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

"The user-friendly and adaptable scheduler allows us to manage various scheduling scenarios."
"I appreciate JAMS for its readily available templates that allow me to create and deliver stand-up presentations within minutes quickly."
"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."
"It's worth its weight in gold and we cannot get rid of it now."
"What my team needs are tools to reliably execute all the jobs, minimize the risks, and support high-availability, and JAMS does the job."
"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."
"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."
"I didn't know about JAMS because I don't have a person with any challenges with the purchase administration. The feature or the user interface is user-friendly because of the readable icons or very descriptive icons. Though I'm a beginning user of JAMS, I had no issues using it."
"Astro by Astronomer has positively impacted my organization by significantly improving developer productivity, reducing downtimes, alleviating overhead associated with upgrades, and delivering nearly a 45% reduction in cloud spending, translating to a high return on investment."
"I would definitely say the migration capabilities save huge amounts of time and effort."
"I think that Astro by Astronomer is a good example of how data orchestration is important to the company when we think about big data and ingestion from many external companies or external institutions that bring to us data that is important to provide final products that can provide to the company the best decision-making in the future for the company regarding revenue, costs, and guidelines for the company that want to grow at a very fast pace."
"Since I started using Astro by Astronomer, it has helped us to scale our data pipeline significantly, and without it, I could not have imagined achieving a flawless data pipeline."
"My experience with customer support has been quite pleasant, as we always get a response."
"Using Astro by Astronomer is definitely improving our team's productivity."
"Astro by Astronomer has many integrations out of the box, making it easy to use and to access documentation."
"Astro by Astronomer has had a positive impact on my organization mainly in terms of time savings and error reduction, since I seek to standardize all the processes within my framework."
"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

"For scalability, I would rate it as seven because when we have a huge volume, sometimes the tool is not so responsive."
"JAMS has built-in reporting. I've never really used it. I tried using it a few years ago and I couldn't figure it out. It was wonky. It could be improved upon."
"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."
"I want JAMS to implement a global search function."
"It does validations when you try to delete an object and if there are any dependencies in place, the deletion process will not proceed... there is no information provided as to what it was that caused the validation to fail... it's quite a tedious process to find which object is getting in the way."
"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."
"All my machines at work are Macs. JAMS client is a Windows-based thing."
"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."
"After using Astro by Astronomer for four years, I can say it has evolved significantly, which is positive; however, improving the debugging experience for complex workflows remains a pain point."
"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 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."
"Astro by Astronomer can be improved always by integrating and being in attention with the capabilities that are emerging in the technology as well."
"Also, if we wanted to import data from outside, the price that they shared with us was higher than the actual tool that we are using right now."
"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."
"I believe there is a need for improvement in Astro by Astronomer, especially regarding the strict limitation of 10 DBT deployments."
"I think there is an aspect of the tool that has caused me some difficulty, which is the scheduler, and I think it could be more intuitive or efficient."
"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 product is reasonably priced, and we don't have any add-ons."
"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."
"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 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."
"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."
"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."
"In the end, you'll find that it's really worth the price. There is some sticker shock, but it's worth every dime."
