A survey revealed that the top uses of open source within organizations are to modernize IT infrastructure and enable digital transformation. In turn, as enablers of digital transformation in IT departments, job schedulers, workload automation, and orchestration tools are among the solutions benefiting from open source implementation. Businesses leverage open source job schedulers and workload automation tools to attain the capabilities of the tools without the barriers of licensing costs and vendor lock-in.

In this article, we explore what open source job schedulers and workload automation tools are, and a list of the top tools.

Job schedulers and workload automation (WLA) tools are a type of software used by businesses to automatically schedule, execute, and monitor workloads across different business platforms. These tools have numerous use cases in IT, HR, and accounting including the automation of ETLs, FTPs, P&Ls, and data warehousing.

Open source job schedulers and WLA provide users with the source code of the tool, enabling them to:

  • modify the code and customize the tools according to business needs.
  • collaborate with community members to share codes, address bugs, and learn software hacks.
  • avoid vendor lock-in

Best practices to choose a job scheduler

Here are a few recommendations to consider while choosing an open source job scheduler and WLA solution:

  • Check the size and collaboration on the forum: The number of open source community members and the codes they share reflects the success of the tool. The most members in the community, the more assistance you can get if you encounter bugs or require help.
  • Check the features of the job scheduler: Most open source job schedulers include features to initiate and execute tasks at the designated time. However, if you will be using the job scheduler or WLA tool to automate sensitive tasks with privileged data, it is important to find a tool that includes monitoring features to generate alerts and audit trails.
  • Consider closed source options as well. In terms of functionality or other aspects, you may be able to find a closed source solution that better fits your requirements

Open-Source vs. Closed-Source

Today, there is more data and far more digital tools than ever before, causing IT workloads to surge. To meet these needs, some organizations have implemented open-source job schedulers.

When a tool, application, or solution is open-source, it means the code exists in the public domain. This allows anyone to access and edit the source code of the application. Users of open-source software can benefit from lower costs and can expect bugs to be quickly fixed because anyone can jump in to improve the code. However, this also means the code is open for hackers to practice on.

Because open-source projects often lack full-time employees, updates can be infrequent and capabilities and features can be sparse. Plus, whereas a closed-source solution is backed by a dedicated team of professionals and support personnel, finding support for open-source software is usually limited to online forums.

Closed-source software means that a person or institution owns the source code and therefore has a dedicated team to develop new features, test new releases, and provide professional support to users.

It would allow you to view your team members’ availability on a real-time basis, assign them tasks, and ensure that those tasks are being completed within a specific time-frame.

Hours Tracking

For many businesses, it is very important to track the number of hours worked by the employees.

Moreover, with the help of the right integrations in your scheduling software, you can get your jobs done from a single interface instead of using multiple software for a single task.

Automatic Notifications

The scheduling software you choose should automatically send the notifications through email or text messages about the important events like tasks/projects assigned, schedule changes, resources booked, etc. to all the team members associated with that particular assignment. This keeps everyone informed and eliminates the problems arising due to communication gaps in the organization.

Assigning a Task to Multiple Team Members

The scheduling software should allow you to assign a task to multiple team members.

This would make your job of team management easier and get the projects completed within the required time frame.
