The Best AWS ETL Tools

datameer + aws

If you are looking to deploy enterprise-level analytics workloads in the cloud on AWS, one of the most important choices is your ETL, data integration, and data pipeline platform.  The ETL tools that come from your cloud vendor, such as AWS, are limited and often fall short.  Look more closely at modern, cloud-native ETL data pipeline platforms such as Datameer.

Cloud ETL Challenges

Deploying or migrating analytics in the cloud has many challenges.  Technical issues include feature differences between on-premises and cloud data platforms, security, and governance.  Non-technical issues include the learning curve for new cloud platform skills and effectively managing and controlling costs.

The majority of cloud analytics projects to date involve data already in the cloud from SaaS applications (Salesforce, Marketo, etc.), cloud services (Google Analytics and Adwords, other marketing services, etc.), or raw data already landing in a cloud data lake.  The risk of moving on-premises data into the cloud has forced enterprises to limit cloud analytics projects, especially in regulated industries where data privacy is critical.

Cloud-only ETL tools recognized this data source pattern, and the move to a new processing model, ELT, and focused exclusively on streamlining simple data integration in cloud data warehouses.

As organizations look to deploy or migrate enterprise-grade analytics workloads in the cloud, several additional challenges come into play:

  • Securely working with on-premises data sources and data that needs to be integrated into the cloud
  • Handling the scale and performance needs of integrating larger on-premises sources into the cloud
  • Implementing more sophisticated transformations to deal with the greater complexity and diversity of data
  • Effectively governing the greater volume and diversity of datasets used for different purposes in the cloud analytics
  • Supporting a greater variety of use cases requiring multiple, different forms of data transformation
  • Effectively managing the cost of both cloud infrastructure consumption and personnel

ETL Options on AWS

For ETL and data integration on AWS, there are four primary options:

  • Subscribe to EMR/Spark or Databricks and hand-code your ETL on top of Spark
  • Subscribe and use AWS’ data integration tool, AWS Glue
  • License a cloud-only data integration platform such as Fivetran or Matillion
  • Use a modern third-party data integration platform that is native on AWS, such as Datameer

GigaOm recently released a report, Analytics in the Cloud: Minimize Pain & Maximize Success, exploring many of the challenges and solutions encountered in a cloud data journey.  In this report, GigaOm discussed many of the shortcomings of the ETL tools offered by the cloud vendors and the reasons why a third-party product makes more sense.

While hand-coding data pipelines may seem like the simplest way to start, this approach does not scale, and it takes a great deal of time to code and deploy each data pipeline.  Many companies using Spark and Databricks for their data pipelines encounter data engineering costs that are spiraling out of control.

While improving ease of use and connectivity to cloud-born data, cloud-only data integration tools have very limited data transformation and platform capabilities.  To learn more about cloud-only data integration platforms, please read our write-ups on Fivetran and Matillion.

AWS Glue

AWS Glue is the ETL tool offered by Amazon Web Services.  Glue is a serverless platform and toolset that can extract data from various sources, transform it in different ways (enrich, cleanse, combine, and normalize), and load and organize data in destination databases, data warehouses, and data lakes.

Glue allows ETL developers to define data pipelines via a visual interface or coding.  Glue also contains a catalog of data flows and resulting datasets.  Glue Studio enables administrators to run and monitor ETL data flows.

Glue Studio is a more traditional ETL tool with a visual job editor and data flow style user interface.  While Glue Studio provides a high-level graphical manner to define a flow, it has an extremely limited set of transformations.  Anything beyond simple transformations such as filters, joins, and mappings require users to write code or SQL.  Glue Studio also has a minimal set of connectors, working only with data sources and destinations running on AWS.

Glue DataBrew is a separate but related product offered by AWS for data preparation.  With the DataBrew interface, you can interactively examine, profile, clean, and transform raw data.  Databrew makes up for the transformation limitations of Glue with a larger library.  As with Glue, the connectors on DataBrew are limited but do expand beyond AWS sources to traditional databases such as Oracle or MySQL running on AWS.

It is important to recognize that Glue and Glue DataBrew are entirely separate products.  Glue is for ETL data pipelines, while  DataBrew is for data preparation.  The only way to combine the two is for Glue to perform extract and load (perhaps into Redshift), then have separate DataBrews preparation jobs to transform the data inside Redshift.

AWS Glue and Glue DataBrews have several limitations:

  • A tiny set of data connectors focused on AWS-owned sources, databases running on AWS, and files from S3 buckets,
  • The inability to securely connect to and work with on-premises data sources,
  • Disjointed data integration jobs that require more sophisticated transformations with logic and job execution split between two tools,
  • The potential for inconsistent security policies and security vulnerabilities between Glue and Glue DataBrews,
  • Very limited data governance features, mostly around security (encryption) and cataloging (via Glue Catalog)

As we compare our list of data challenges for enterprise-grade analytics workloads in the cloud with AWS Glue’s limitations, it is clear Glue will not meet the enterprise-level requirements for ETL and data integration in the cloud on AWS.

Also, from our examination of cloud-only data integration solutions such as Fivetran and Matillion, these products do not meet many of our enterprise-level requirements as well.
