About the Services
Apache Airflow
Apache Airflow is a free, open-source platform for developing batch-oriented workflows. It launched in 2014 and has big-name companies like Airbnb, Lyft, and Etsy in its portfolio. It has a growing community of over 2,000 contributors and many users worldwide.
Apache Airflow uses a workflow management system. This system handles automating and monitoring data integration processes. It can handle simple data transfers and complex machine-learning workflows. The user interface is easy to use, so you can focus on your work instead of minding a confusing interface.
But having that simple interface has a caveat. Open-source platforms need technical expertise, and Airflow is no different. You can start with several options to install. If you don’t want to hire experts to do this for you, you need to know about Python and some required libraries and even about Docker Containers for a seamless cloud deployment.
Apache Airflow also doesn’t have a record of privacy and security certifications, but it has security features like role-based access control and encryption. So, your data is safe from prying eyes. It also provides logging and auditing capabilities. So, this will help identify and investigate any security or privacy incidents. Companies with stringent security and privacy requirements trust Apache Airflow. But again, either you need some more technical expertise, or pay for someone who knows how to secure Airflow in your environment.
Pentaho Data Integration
Pentaho Data Integration (PDI) is an ETL tool with different offerings. You can choose between open-source and Enterprise Edition. Hitachi Vantara launched this in 2004. Since then, this tool has been serving a growing number of customers worldwide, and the feedback is positive.
PDI enables you to extract, transform, and load (ETL) data from a variety of sources. With PDI, you can integrate data to create meaningful insights and reports. These reports can help in business decisions.
PDI’s user interface is intuitive and easy to navigate. However, it can get slow at times, and customization of the UI is limited, according to some reviews in Gartner Peer Insights. And only 68% Would Recommend according to the same reviews.
PDI is a product you need to install and configure. That means you take care of security and privacy concerns on your own. Yet, you can deploy PDI in the cloud and use whatever certifications the cloud provider has. PDI also uses security providers like LDAP, Secure Socket Layers, and more. So, PDI is not lax on security and privacy.
Skyvia
Skyvia is a no-code cloud data integration platform for many data integration scenarios. It’s an all-rounder tool for ETL, ELT, Reverse ETL, data migration, one-way and bi-directional data sync, workflow automation, and more.

So, if your data source is so unique and recent, look for a connector in the community first. But if nobody made one for it yet, prepare to roll up your sleeves and code.
