Now that much of the world’s data resides in cloud or hybrid data warehouses and data lakes, many organizations are turning their focus to extract, transform, and load (ETL) modernization.
That is, they are shifting from on-premises ETL solutions to serverless ETL solutions that offer lower cost and maintenance requirements, increased scalability, and easier integration with other cloud services and applications.
To illustrate this point, the market for cloud computing data integration services is expected to more than double in the coming years, growing from $445.3 billion in 2021 to $947.3 billion by 2026.
In this blog, we’ll explore the option to migrate from IBM DataStage on-prem solution to AWS Glue serverless ETL solution. We’ll cover the benefits of serverless data integration and then outline key steps for a successful migration to AWS Glue.
IBM DataStage is an ETL solution that helps businesses design, develop, and run jobs that collect and deliver data. It was originally designed as an on-premises solution, which requires license-holders to install the software locally, handle software upgrades internally, and manage/maintain the infrastructure that runs it.
Though DataStage is available on the cloud via IBM Cloud Pak for Data, many customers are still using the DataStage on-prem solution.
AWS Glue is a serverless, cloud-native data integration service that helps customers discover, prepare, and combine data for analytics, machine learning, and application development.
It is a fully managed data integration service that allows companies to categorize their data, clean it, enrich it, and move it reliably between various data stores and data streams without the responsibility for infrastructure management and maintenance.
For organizations looking to increase the performance and throughput of their data integration solutions, AWS Glue can be a good fit. It has built-in Spark and its own compute and processing capability, which supports batch and streaming data and handles concurrent jobs well.
Additionally, it integrates natively with the AWS ecosystem, which includes technology and tools for IoT, streaming, analytics, machine learning, natural language processing, and much more. It also integrates easily with third-party technologies, such as non-native connectors.
Legacy ETL solutions are being put to the test as data volumes continue to grow and more users wish to engage with the data.
With much of our data now residing on a big data landscape, older data integration solutions often struggle to keep up with modern use cases that demand concurrent workloads, large data loads, real-time and event-based jobs, and streaming data. Or they may struggle with poorly designed queries that affect performance. In any case, users become frustrated by slow data (or no data) and it loses its value.
Moving to a cloud-based, serverless data integration solution offers several benefits that help overcome these challenges:
If your organization is planning a migration from IBM DataStage to AWS Glue, there are several steps to keep in mind. Below are some helpful processes to consider when making this important transition.
When it comes to development and testing environments:
When you reach the deployment environment:
Lastly, when it comes to the deployment process, consider these steps:
ETL code conversion traditionally has been a complex and time-consuming manual effort. Today, you can leverage ETL code converters to reduce the level of effort and improve the quality of converted code. For example, Wavicle’s code converters can successfully convert 90% or more of the DataStage mappings. As a result, the overall effort of conversion is greatly reduced.
DataStage and AWS Glue are both rated among the best ETL solutions available and can both be good options for your organization, depending on your data management environment. If you are integrating data into your cloud environment with requirements for real-time data integration and concurrent workloads, you might consider the advantages of AWS Glue.
ETL modernization is an important but challenging process for many organizations. To help you identify and deploy the best tools for your organization’s use cases, Wavicle offers expert consulting services to help you assess, mobilize, migrate, and modernize your AWS environment.
