Apache Airflow vs IBM BPM vs WorkflowGen comparison

Apache Airflow is an open-source workflow management system (WMS) that is primarily used to programmatically author, orchestrate, schedule, and monitor data pipelines as well as workflows. The solution makes it possible for you to manage your data pipelines by authoring workflows as directed acyclic graphs (DAGs) of tasks. By using Apache Airflow, you can orchestrate data pipelines over object stores and data warehouses, run workflows that are not data-related, and can also create and manage scripted data pipelines as code (Python). 

Apache Airflow Features

Apache Airflow has many valuable key features. Some of the most useful ones include:

• Smart sensor: In Apache Airflow, tasks are executed sequentially. The smart sensors are executed in bundles, and therefore consume fewer resources.

• Dockerfile: By using Apache Airflow’s dockerfile feature, you can run your business’s Airflow code without having to document and automate the process of running Airflow on a server. 

• Scalability: Because Apache Airflow has a modular architecture and uses a message queue to orchestrate an arbitrary number of workers, you can easily scale it. 

• Plug-and-play operators: With Apache Airflow, you can choose from several plug-and-play operators that are ready to execute your tasks on many third-party services.

Apache Airflow Benefits

There are many benefits to implementing Apache Airflow. Some of the biggest advantages the solution offers include:

• User friendly: Using Apache Airflow requires minimal python knowledge to get started.

• Intuitive user interface: The Apache Airflow user interface enables you to visualize pipelines running in production, monitor progress, and also troubleshoot issues when needed.

• Easy integration: Apache Airflow can easily be integrated with cloud platforms (Google, AWS, Azure, etc).

• Visual DAGs: Apache Airflow’s visual DAGs provide data lineage, which facilitates debugging of data flows and also aids in auditing and data governance. 

• Flexibility: Apache Airflow provides you with several ways to make DAG objects more flexible. At runtime, a context variable is passed to each workflow execution, which is quickly incorporated into an SQL statement that includes the run ID, execution date, and last and next run times.

• Multiple deployment options: With Apache Airflow, you have several options for deployment, including self-service, open source, or a managed service.

• Several data source connections: Apache Airflow can connect to a variety of data sources, including APIs, databases, data warehouses, and more.  

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the Apache Airflow solution.

A Senior Solutions Architect/Software Architect says, “The product integrates well with other pipelines and solutions. The ease of building different processes is very valuable to us. The difference between Kafka and Airflow, is that it's better for dealing with the specific flows that we want to do some transformation. It's very easy to create flows.”

An Assistant Manager at a comms service provider mentions, “The best part of Airflow is its direct support for Python, especially because Python is so important for data science, engineering, and design. This makes the programmatic aspect of our work easy for us, and it means we can automate a lot.”

A Senior Software Engineer at a pharma/biotech company comments that he likes Apache Airflow because it is “Feature rich, open-source, and good for building data pipelines.”

IBM BPM is a business process management tool that provides a robust set of tools to author, test, and deploy business processes, as well as full visibility and insight to managing those business processes. The solution provides tooling and run time for process design, execution, monitoring, and optimization, along with basic system integration support. To support various levels of complexity and involvement with business process management, there are two different editions of the product: IBM BPM and IBM BPM Express.

IBM BPM Features

IBM BPM has many valuable key features. Some of the most useful ones include:

• Process designer authoring tool
• Collaborative editing and immediate playback of processes
• Interactive user interfaces
• Process rules based on IBM Operational Decision Manager
• IBM Integration Designer (BPEL and SOA)
• Designing and building case management systems
• Process portal
• Real-time monitoring and reporting
• Performance analytics and optimizer
• Performance data warehouse
• IBM Process Center with a shared asset repository
• IBM Process Federation Server
• Built-in enterprise service bus (ESB)
• Transaction support
• Integration adapters
• Network deployment support
• High availability: clustering and unlimited cores

IBM BPM Benefits

There are many benefits to implementing IBM BPM. Some of the biggest advantages the solution offers include:

• Increased efficiency and cost savings: IBM BPM can help you optimize existing processes and incorporate more structure into the development of new processes by removing process redundancies and bottlenecks.

• More scalable processes: The solution enables better process execution and workflow automation, which transfers well when scaling processes.

• Greater transparency: Because IBM BPM’s process automation clearly defines owners for tasks along the process, it provides more transparency and accountability throughout a given process. In turn, this fosters more communication among teams.

• Less dependency on development teams: IBM BPM offers low-code features which remove potential dependencies on development. Business users can be onboarded onto these tools quickly and easily, thereby increasing process automation across the company.

Reviews from Real Users

IBM BPM is a solution that stands out when compared to many of its competitors. Some of its major advantages are that it’s good for developing complex apps, is robust, and has helpful team management and process performance features.

Zoran C., Owner/CEO at IT SPHERE, says, “It is perfect if you have to develop complex apps without much coding (only java script). It is also good if you don't have much IT resources in your company and would like to involve business analysts in the process of developing apps. My opinion is that it can do about 50% of all developers' work.”

Suhas V., BPM Architect at GBM, mentions, “Overall the solution is robust and has the ability to integrate with any product for complex workflows."

A BPM Consultant at a financial services firm comments, "Some of the features that I like the most are team management and process performance. They are both very useful and very powerful with regard to the workflow."

A Digital Banking & Innovation Director at a financial services firm expresses, “The processing functionality makes it easy to change processes and workflows easily.”
