Simplify ETL Migration to AWS Glue Serverless Data Integration

Why Top Companies are Migrating Legacy ETL to Cloud

Traditional ETLs present limitations in meeting modern business intelligence and analytics requirements. Legacy ETL tools typically follow a batch-oriented approach for processing data that can result in hours or days-old data, thereby reducing the required effectiveness. Some other common challenges with traditional ETL include:

• High licensing cost
• Non-availability of usage-based pricing
• Lack of scalability and complex to manage
• Inability to seamlessly fit with modern data lake tools and architectures

Today’s top companies are leveraging  the cloud to simplify infrastructure and ensure data architectures support machine learning use cases. ETL is a key part of the data flow that needs to be migrated to maximize gains achieved by shifting to the cloud.

Introduction of AWS Glue Platform

AWS Glue is a serverless cloud-based ETL service that is powered by a big data engine to provide data-intensive computation. It facilitates all the data integration services to transform data for optimal use in a cost-effective pay-as-you-go manner.

AWS Glue consists of components such as a central metadata repository, an ETL engine and a flexible scheduler that provides data-intensive computation. Another key service is AWS Glue Studio, the visual drag-and-drop tool that enables ETL development without the need for hand-coding, which is ideal for ETL developers that are familiar with popular tools like Informatica or Ab Initio.

Benefits of AWS Glue

Glue is different from other ETL products in several ways. Let’s take a look at the benefits of this modern data integration tool.

• Completely serverless thereby reducing infrastructure setup and management costs
• Glue runs on a highly scalable Spark execution engine that allows users to pay only for the resources they consume while the jobs are running
• Automatic schema inference
• Seamless development and execution experience with AWS Glue Studio
• Easily synchronize Glue jobs to different environments

AWS Glue helps build data lake and data warehouse environments and fits seamlessly in the AWS Analytics stack including EMR, Redshift and SageMaker for a comprehensive data platform.

Pain of Migrating ETL

AWS Glue is a powerful serverless cloud ETL service that provides advantages for modern data integration needs, but migrating legacy ETL to AWS Glue is no easy feat. Challenges that can hold you back from successfully migrating from one ETL to another include:

• Difficult to precisely estimate time and cost of migration
• Time consuming and error-prone
• Unexpected challenges can result in significant re-work effort and increased conversion costs
• Requires rigorous testing
• Incompatibility issues due to environmental changes

The manual approach to migration is tedious and resource-intensive, delaying the migration decision for organizations.
