It is a visitor submit coauthored with LaunchDarkly.
The LaunchDarkly function administration platform equips software program groups to proactively cut back the chance of transport unhealthy software program and AI purposes whereas accelerating their launch velocity. On this submit, we discover how LaunchDarkly scaled the interior analytics platform as much as 14,000 duties per day, with minimal enhance in prices, after migrating from one other vendor-managed Apache Airflow resolution to AWS, utilizing Amazon Managed Workflows for Apache Airflow (Amazon MWAA) and Amazon Elastic Container Service (Amazon ECS). We stroll you thru the problems we bumped into through the migration, the technical resolution we applied, the trade-offs we made, and classes we discovered alongside the best way.
The problem
LaunchDarkly has a mission to allow high-velocity groups to launch, monitor, and optimize software program in manufacturing. The centralized information staff is accountable for monitoring how LaunchDarkly is progressing towards that mission. Moreover, this staff is accountable for almost all of the corporate’s inner information wants, which embody ingesting, warehousing, and reporting on the corporate’s information. A few of the giant datasets we handle embody product utilization, buyer engagement, income, and advertising information.
As the corporate grew, our information quantity elevated, and the complexity and use instances of our workloads expanded exponentially. Whereas utilizing different vendor-managed Airflow-based options, our information analytics staff confronted new challenges on time to combine and onboard new AWS companies, information locality, and a non-centralized orchestration and monitoring resolution throughout totally different engineering groups inside the group.
Resolution overview
LaunchDarkly has an extended historical past of utilizing AWS companies to resolve enterprise use instances, similar to scaling our ingestion from 1 TB to 100 TB per day with Amazon Kinesis Information Streams. Equally, migrating to Amazon MWAA helped us scale and optimize our inner extract, remodel, and cargo (ETL) pipelines. We used current monitoring and infrastructure as code (IaC) implementations and ultimately prolonged Amazon MWAA to different groups, establishing it as a centralized batch processing resolution orchestrating a number of AWS companies.
The answer for our transformation jobs embody the next parts:
Our unique plan for the Amazon MWAA migration was:
- Create a brand new Amazon MWAA occasion utilizing Terraform following LaunchDarkly service requirements.
- Raise and shift (or rehost) our code base from Airflow 1.12 to Airflow 2.5.1 on the unique cloud supplier to the identical model on Amazon MWAA.
- Minimize over all Directed Acyclic Graph (DAG) runs to AWS.
- Improve to Airflow 2.
- With the flexibleness and ease of integration inside AWS ecosystem, iteratively make enhancements round containerization, logging, and steady deployment.
Steps 1 and a couple of have been executed rapidly—we used the Terraform AWS supplier and the present LaunchDarkly Terraform infrastructure to construct a reusable Amazon MWAA module initially at Airflow model 1.12. We had an Amazon MWAA occasion and the supporting items (CloudWatch and artifacts S3 bucket) working on AWS inside every week.
Once we began reducing over DAGs to Amazon MWAA in Step 3, we bumped into some points. On the time of migration, our Airflow code base was centered round a customized operator implementation that created a Python digital surroundings for our workload necessities on the Airflow employee disk assigned to the duty. By trial and error in our migration try, we discovered that this tradition operator was primarily depending on the conduct and isolation of Airflow’s Kubernetes executors used within the unique cloud supplier platform. Once we started to run our DAGs concurrently on Amazon MWAA (which makes use of Celery Executor staff that behave otherwise), we bumped into a couple of transient points the place the conduct of that customized operator may have an effect on different working DAGs.
Presently, we took a step again and evaluated options for selling isolation between our working duties, ultimately touchdown on Fargate for ECS duties that may very well be began from Amazon MWAA. We had initially deliberate to maneuver our duties to their very own remoted system reasonably than having them run straight in Airflow’s Python runtime surroundings. Because of the circumstances, we determined to advance this requirement, remodeling our rehosting undertaking right into a refactoring migration.
We selected Amazon ECS on Fargate for its ease of use, current Airflow integrations (ECSRunTaskOperator), low price, and decrease administration overhead in comparison with a Kubernetes-based resolution similar to Amazon Elastic Kubernetes Service (Amazon EKS). Though an answer utilizing Amazon EKS would enhance the duty provisioning time even additional, the Amazon ECS resolution met the latency necessities of the information analytics staff’s batch pipelines. This was acceptable as a result of these queries run for a number of minutes on a periodic foundation, so a pair extra minutes for spinning up every ECS job didn’t considerably influence total efficiency.
Our first Amazon ECS implementation concerned a single container that downloads our undertaking from an artifacts repository on Amazon S3, and runs the command handed to the ECS job. We set off these duties utilizing the ECSRunTaskOperator in a DAG in Amazon MWAA, and created a wrapper across the built-in Amazon ECS operator, so analysts and engineers on the information analytics staff may create new DAGs simply by specifying the instructions they have been already aware of.
The next diagram illustrates the DAG and job deployment flows.
When our preliminary Amazon ECS implementation was full, we have been in a position to minimize all of our current DAGs over to Amazon MWAA with out the prior concurrency points, as a result of every job ran in its personal remoted Amazon ECS job on Fargate.
Inside a couple of months, we proceeded to Step 4 to improve our Amazon MWAA occasion to Airflow 2. This was a serious model improve (from 1.12 to 2.5.1), which we applied by following the Amazon MWAA Migration Information and subsequently tearing down our legacy assets.
The fee enhance of including Amazon ECS to our pipelines was minimal. This was as a result of our pipelines run on batch schedules, and due to this fact aren’t energetic always, and Amazon ECS on Fargate solely prices for vCPU and reminiscence assets requested to finish the duties.
As part of Step 5 for steady evaluation and enhancements, we enhanced our Amazon ECS implementation to push logs and metrics to Datadog and CloudWatch. We may monitor for errors and mannequin efficiency, and catch information take a look at failures alongside current LaunchDarkly monitoring.
Scaling the answer past inner analytics
In the course of the preliminary implementation for the information analytics staff, we created an Amazon MWAA Terraform module, which enabled us to rapidly spin up extra Amazon MWAA environments and share our work with different engineering groups. This allowed the usage of Airflow and Amazon MWAA to energy batch pipelines inside the LaunchDarkly product itself in a few months shortly after the information analytics staff accomplished the preliminary migration.
The quite a few AWS service integrations supported by Airflow, the built-in Amazon supplier package deal, and Amazon MWAA allowed us to broaden our utilization throughout groups to make use of Amazon MWAA as a generic orchestrator for distributed pipelines throughout companies like Amazon Athena, Amazon Relational Database Service (Amazon RDS), and AWS Glue. Since adopting the service, onboarding a brand new AWS service to Amazon MWAA has been easy, usually involving the identification of the present Airflow Operator or Hook to make use of, after which connecting the 2 companies with AWS Id and Entry Administration (IAM).
Classes and outcomes
Via our journey of orchestrating information pipelines at scale with Amazon MWAA and Amazon ECS, we’ve gained useful insights and classes which have formed the success of our implementation. One of many key classes discovered was the significance of isolation. In the course of the preliminary migration to Amazon MWAA, we encountered points with our customized Airflow operator that relied on the precise conduct of the Kubernetes executors used within the unique cloud supplier platform. This highlighted the necessity for remoted job execution to keep up the reliability and scalability of our pipelines.
As we scaled our implementation, we additionally acknowledged the significance of monitoring and observability. We enhanced our monitoring and observability by integrating with instruments like Datadog and CloudWatch, so we may higher monitor errors and mannequin efficiency and catch information take a look at failures, enhancing the general reliability and transparency of our information pipelines.
With the earlier Airflow implementation, we have been working roughly 100 Airflow duties per day throughout one staff and two companies (Amazon ECS and Snowflake). As of the time of scripting this submit, we’ve scaled our implementation to a few groups, 4 companies, and execution of over 14,000 Airflow duties per day. Amazon MWAA has grow to be a vital element of our batch processing pipelines, growing the velocity of onboarding new groups, companies, and pipelines to our information platform from weeks to days.
Wanting forward, we plan to proceed iterating on this resolution to broaden our use of Amazon MWAA to extra AWS companies similar to AWS Lambda and Amazon Easy Queue Service (Amazon SQS), and additional automate our information workflows to help even larger scalability as our firm grows.
Conclusion
Efficient information orchestration is crucial for organizations to collect and unify information from numerous sources right into a centralized, usable format for evaluation. By automating this course of throughout groups and companies, companies can remodel fragmented information into useful insights to drive higher decision-making. LaunchDarkly has achieved this through the use of managed companies like Amazon MWAA and adopting greatest practices similar to job isolation and observability, enabling the corporate to speed up innovation, mitigate dangers, and shorten the time-to-value of its product choices.
