ETL in the cloud

AWS Glue

AWS Glue is a nice fit for companies that use SQL databases, AWS and Amazon S3 storage services. AWS Glue enables you to clean, validate, organize and load data from disparate static or streaming data sources into a data warehouse or a data lake. It also allows you to process semi-structured data such as clickstream (e.g., website hyperlinks) and process logs. Its strength is in its ability to work with SQL, which many companies have competence in. On the programming side, AWS Glue executes jobs using either Scala or Python code.

With AWS Glue, you can schedule ETL jobs based on a schedule or event, or you can trigger jobs as soon as data becomes available. AWS Glue is an on-demand tool that automatically scales to accommodate the processing and storage resources that you need, and that gives you visibility of runtime metrics while it processes.

AWS Glue integrates well with other AWS systems and processes, so if AWS is your primary data repository and processor, AWS Glue works well. It also has APIs for third party JDBC (JAVA)-accessible databases like DB2, MySQL, Oracle, SyBase, Apache Kafka and MongoDB.

AWS offers free online courses. It also provides certification programs. Pricing is free for the first million accesses/objects stored and is billed on a monthly basis that is based upon usage thereafter.

What is an ETL tool?

Today, data analytics plays a major role in corporate decision making. It is able to do this because data is culled from a variety of sources and then assembled in a single data repository that corporate decision makers can access. When data is combined from different areas throughout the company, corporate decision makers get a 360-degree view of what is going on. This enables them to make more informed decisions.

For example, if a vice president of sales wants to know why a certain product isn’t selling well, he/she can query a central data analytics repository which contains all of the information on that particular product from throughout the enterprise.

The sales VP can see the customer complaints about the product that customer service logged, as well as the number of product returns that the warehouse processed. He/she can also see that engineering is working on a revision of the product to cure the defects that have been reported. The VP now has a thorough understanding of why the product hasn’t been doing as well in revenues as was projected.

How do ETL tools work?

ETL software obtains data from one source, transforms the data into a form that is acceptable for another source and then moves the data to the new target source. ETL software is an automated software tool. When companies use ETL software, they no longer have to convert data from one source to another by hand. This saves time, effort and manual errors.

What do you need the ETL for?

Are you going to be pulling data from different sources that range from unstructured or semi-structured IoT data to legacy system data that resides on internal servers and mainframes? Or is your company almost wholly cloud-based, with a clear preference for an ETL solution that operates within the cloud where most of your data and applications are hosted? What if your company has data and systems that are both on premises and cloud based? What’s the best choice for that scenario?

How do you want to prepare your data?

Is the generic formatting (system to system or database to database) that your ETL tool comes pre-packaged with going to meet your data cleaning and formatting needs, or do you need to add extra edit rules to data?

How well can you support and leverage your ETL tool?

If you are a smaller company, do you have skilled personnel on board who are trained in ETL methods and tools? Even if you have this personnel on board, do you have a need to also have your non-IT end business users use the ETL software?

Wrapping Up

Data integration is one of the most persistent challenges for IT teams. What ETL tools bring to the table is a simplified way of moving data from system to system and from data repository to data repository. These ETL tools comes in a wide variety of flavors that can meet the needs of enterprises with complex data and system integration needs in hybrid environments to smaller companies that lack IT expertise and must watch their budgets. The ETL tool your business chooses will depends on its specific use cases and budget.
