Cloud-Based ETL – Tools & How it Works

Cloud-based ETL tools

Do you know that these days, organizations generate vast amounts of data from various sources in raw & unstructured form? But with this, they do place a lot of stress on how to process this data & transform it into a meaningful format for actionable insights.

Well, now they don’t have to take stress because, at this point, ETL (Extract, Transform, Load) comes into play. With the advent of cloud-based ETL, the process will become more efficient & scalable to let the tools perform their functions. 

So, after knowing this, everyone even wants to know that how the process works & which tools are necessary to be used. For that, everyone should take a look at this information blog & explore what cloud-based ETL is, how it works, and some of the most popular tools available on the market.

What is Cloud-Based ETL?

In this process, ETL stands for Extract, Transform, & Load. And this is used in data warehousing & data integration to collect data from various sources that can be transformed into a suitable format that can be used by everyone. After the transformation, the data is all set to load into the destination system, such as a data warehouse or data lake. 

From this, everyone gets to know that the main process of this is to perform different functions using cloud services & infrastructure.

Benefits of Cloud-Based ETL

Better Cost-Efficiency

Everyone gets to experience benefits from cloud-based solutions since they only have to pay for the items and procedures they really utilize. It also does away with the requirement for large upfront hardware and software expenses.

Improved Flexibility

The use of tools in the process can even integrate a wide range of data sources & destinations, through which people will be able to experience this kind of benefit.

Maintenance & Updates

Another benefit that all get is related to maintenance & updates. And when it comes to cloud service providers, they get to handle maintenance, updates, and security, allowing organizations to focus on their core business.

As, you get to know what the process is & what kind of benefits it has to offer you. Consequently, let us now see ETL and its operation. Let’s examine it and see how it operates: 

How Does Cloud-Based ETL Works?

The process for working does follow the same fundamental principle as traditional ETL but leverages the cloud for better & improved power as well as flexibility. For more understanding, let’s have a look at the step-by-step breakdown of the process:


The first step involves the extraction of data from various sources. These do involve the extraction from different sources, like databases, APIs, flat files, or even other cloud services. And when it is used with ETL tools, it often comes with pre-built connectors & integrations to simplify the process. Additionally, following this type of processing, the collected data is typically kept in a cloud staging area for a little while.


Once the extraction step is completed, there is a need to transform the data into a suitable & meaningful format. So, for that transformation, do include a variety of options, such as:

  • Cleaning: In the cleaning part, the duplicate data is removed to correct the errors, & missing values are handled.
  • Enriching: At this step, additional information or context is all set to be added to the data.
  • Aggregating: In the aggregating step, the summarizing of data is done to obtain insights.
  • Normalizing: The data after the completion of all steps is ready to be structured in a consistent format.


Now, the final step of the work is loading, where the data that is transformed into a usable form is set to be uploaded into the destination system, such as a data warehouse or data lake. Here, the usage of tols to load the data ensures that the work done on these is done efficiently & securely, often providing options for incremental loads & real-time updates.

With this, while performing the ETL process, everyone is so interested in knowing which tools are being used. For that, let’s look below & learn more:

Popular Cloud-Based ETL Tools

AWS Glue

AWS Glue is the fully managed ETL, which is provided by Amazon Web Services. In that way, the users are allowed to prepare & transform the data for analytics, machine learning, & even application development. 

Azure Data Factory

This is also a tool of ETL & data integration from Microsoft Azure. Here, the users are allowed to create, schedule, & orchestrate ETL workflows, which, as a result, provide support for a wide range of data sources & destinations.

Google Cloud Dataflow

This tool is a unified stream & batch processing service that provides a simple, flexible programming model for ETL and analytics, integrating seamlessly with other Google Cloud services.

Talend Cloud

This is a versatile cloud-based data integration platform that is prepared in such a way that it provides a range of ETL tools for data extraction, transformation, and loading.


The above helpful information gives everyone the idea that this ETL has revolutionized the way organizations handle data for integration & transformation. As data continues to grow in volume and complexity, cloud-based ETL solutions will play an increasingly critical role in helping organizations derive valuable insights from their data.
