Carlos Alberto Marangon - PeerSpot reviewer
Automate complex workflows with seamless AWS integration
Step Functions provide seamless integration with AWS services, which enhances the speed of application development. The JSON app launched recently allows us to define data execution more easily. The Standard Workflows feature includes error replay capabilities, which are crucial for efficient error management. The Amazon State Language (ASL) in JSON format facilitates workflow automation and accelerates the deployment of Step Functions.
JuanGonzalez6 - PeerSpot reviewer
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

"What I like the most about Amazon Step Functions is how easy it is to use."
"Overall, I would rate AWS Step Functions at least nine out of ten."
"AWS Step Functions acts as a high-level layer, allowing us to seamlessly integrate with microservices."
"If you want to create a workflow to call one Lambda function after another, and other serverless features, it could save you a ton of money. That's for sure."
"The number of historical events is great."
"It is a scalable solution."
"One can rate all the calls and that is a good feature."
"The JSON app launched recently allows us to define data execution more easily."
"I have found the scheduling feature the most valuable. I can map dependencies by using ASG-Zena. It gives a nice, quick visualization as to where things are."
"The most valuable feature is the FTP file transfer."
"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."
"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."
"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."
"I like the whole product, but specifically, I like the license part. It's very easy to acquire a license for this product."
"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."
"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."
 

Cons

"The solution's data size limit can be improved."
"Setup took about one day. We had some errors to understand in the beginning, but now everything is working good."
"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."
"I would like to see more data transformation features in Amazon Step Functions like additional operators and logic."
"The solution's pricing could be cheaper. It is cheaper than Airflow."
"If AWS Step Functions keeps adding more integrations, it would be even better."
"One area for improvement is the payload size. Currently, I sometimes have to save data as a file since I cannot pass it within Step Functions, necessitating caching in processes."
"The pricing of the solution can be improved."
"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."
"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 documentation has room for improvement."
"The UI is not intuitive, and it would be nice if there was a web interface."
"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."
"In the next release, I would like the user experience to be improved. The user interface should be more appealing to gen-z."
"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."
"One area where it could be improved is communication between the different servers. Sometimes there are processes that have already been completed but we get a status notification that they're still active."
 

Pricing and Cost Advice

"The solution's price is reasonable."
"The solution is expensive."
"The pricing and the licensing are good. It is affordable and can be used to improve and optimize productivity."
