But what if you want to self managed Apache Airflow? When I speak with developers, there are sometimes reasons why a managed service might not fit their needs. Some of the common things that come up include: whether you need the increase level of access, a greater level of control of the configuration of Apache Airflow have the need to have the very latest versions or features of Apache Airflow if you have the need to run workflows that use more resources that managed services provide (for example, need significant compute) Total Cost Ownership One thing to consider when assessing managed vs self managed is the cost of the managed service against the total costs of you having to do the same thing.

In this post, Part Two, we will do the same thing but automate the same example ELT workflow using Amazon EMR. Make sure you recap the setup from Part One.

  • Automating your ELT Workflows with Managed Workflows for Apache Airflow - Part One

    Calendar Apr 21, 2021 |  Stopwatch  18 minute read

    update: I have changed the post to use standard Apache Airflow variables rather than using AWS Secrets Manager. Part One - Automating Amazon Athena As part of an upcoming DevDay event, I have been working on how you can use Apache Airflow to help automate your Extract, Load and Transform (ELT) Workflows. Amazon Athena and Amazon EMR are two AWS services that help customers who have existing SQL skills/expertise and are looking at tools such as Presto or Apache Hive when undertaking those transformations.

  • TIL: Testing an Amazon Cloudwatch alarm

    Calendar Jan 7, 2021 |  Stopwatch  2 minute read

    Today I was setting up an application load balancer that sits in front of a test application I have put together. Setting this up was super easy, and very quickly I had my domain pointing to the alias and serving requests. As part of the setup, I wanted to monitor the application load balancer to let me know when requests were failing to the downstream application (anything other than an HTTP 200) and so I set this up super easily in Amazon Cloudwatch.
