Right now, this doesn’t do anything besides increase our AWS bill. Once it is in the ready state, we have a fancy Environment that allows us to log in.
Waiting for Environments to spin up or reconfigure is not a fun experience. You’ll want to avoid messing this up too many times.

Now you’ll need patience while the Environment is created because it can take between 25 and 30 minutes, and if you later update it, that may take around 15 minutes. It’s also good to increase the log level here to get more insights into what’s going on in the Environment.

You can optionally set paths in S3 to a requirements.txt that specifies which additional Python packages to install and a path to a Plugins.zip, also in S3 that can contain other dependencies. The role the Environment can use is another mandatory configuration. You have to specify an S3 path where your workflow definitions (DAGs, more on that later) will be stored. Once you have the VPC and the role, you can create your Environment, which is highly available by default. Strategies to improve the situation may be the topic for a future blog post - let us know if you’re interested. It’s not great from a security perspective, but there isn’t too much we can do about this for now. The role requires access to all the services you intend to use in the workflows, which means it will have fairly broad permissions. This Environment will be responsible for hosting our ETL workflows. Additionally, we need to create a role that our Environment can use to trigger other services. You need to have a VPC with at least two private subnets to start using the service. While not a memorable name, it is descriptive and a well-built service. In AWS, MWAA or Managed Workflows for Apache Airflow provides a managed Airflow Environment. Additionally, it provides a single interface to watch all your ETL processes, which people in operations roles will value.

Here is where Airflow can help.Īirflow is a popular open-source tool that allows you to describe your ETL workflows as Python code and makes it possible to schedule and visually monitor these workflows while at the same time providing broad integrations in the AWS ecosystem and with 3rd party tools. ETL processes tend to increase in complexity over time, and you’ll find that you need to schedule and orchestrate different services in conjunction with each other to process your data. Standard tools are Glue, Spark, Elastic Map Reduce (EMR), Lambda, or Athena. It refers to Extract-Transform-Load and describes preparing data for analysis by manipulating or enriching it somehow. Acronyms are annoying, but we’ll continue using ETL here. Its main task is to orchestrate ETL processes. If you’re familiar with the AWS ecosystem, you can think of Airflow as a mix of step functions and Glue workflows. We can report that the tool is pretty cool, and that’s why we want to give you some insight into it. Airflow kept showing up on our radar, and when the first projects came around, we dove deep into it. If you think similar to us, you’ll first ignore these projects until the name keeps popping up, and then you begin investigating what all the buzz is about.
Meaning you won’t have a clear idea in your head of what the service does when you first come upon the name.

The Apache ecosystem is full of projects, and often, the project’s name doesn’t indicate what the tool does (think Pig, Cassandra, Hive, etc.). In the end, we’ll bring everything together with an example use case.
This post will explain which problems the service solves, how you can get started, and the most important concepts you need to understand. Apache Airflow doesn’t only have a cool name it’s also a powerful workflow orchestration tool that you can use as Managed Workflows for Apache Airflow (MWAA) on AWS.
