About the Services
AWS Glue
AWS Glue is a serverless data integration tool from Amazon. It helps you extract data from other cloud services offered by Amazon Web Services (AWS). Then, incorporate it into data lakes and data warehouses. It offers a cost-efficient way to process data for good use in analytics and machine learning. AWS Glue provides a performance-optimized infrastructure for running Apache Spark for data integration. It supports batch and stream processing. And it speeds up data ingestion, processing, and integration.
AWS Glue covers various data integration scenarios. This includes ETL, ELT, reverse ETL, data ingestion, and replication.
AWS Glue encrypts all customer data at rest using industry-standard encryption algorithms. AWS Glue also provides customers with fine-grained access control over their metadata. It is compliant with various security standards such as SOC 1/2/3, PCI DSS Level 1, and HIPAA Eligible Service.
Apache Nifi
Apache Nifi is an open-source, easy-to-use system to process and distribute data. Brand new UI version 1 was released in 2016. More than 2400 companies are using Apache Nifi, according to Enlyft.
Apache Nifi works on-premise or with any cloud provider. You can download, install, and configure Apache Nifi on Linux, Mac, and Windows machines. Keep in mind that Nifi may require technical skills. You can’t install it and build ETL pipelines in minutes. But once you complete your configuration, you can prepare data pipelines in a browser.
There are no limits on the number of data sources and destinations in a pipeline. You are only limited by the processing capacity of your machine.
Data security and privacy are your responsibility. But if you deploy the system in AWS or Azure, you can leverage their security and privacy certifications.
Skyvia
Skyvia is a no-code cloud data integration platform for many data integration scenarios. It’s an all-rounder tool for ETL, ELT, Reverse ETL, data migration, one-way and bi-directional data sync, workflow automation, and more.

Connectors
AWS Glue
AWS Glue supports the following connection types:
• JDBC-compatible data sources,
• Amazon Relational Database Service (Amazon RDS),
• Amazon Redshift,
• Amazon DocumentDB,
• Kafka,
• MongoDB,
• MongoDB Atlas.
But there’s no mention of the latest number of data connectors available for AWS Glue.
AWS Glue provides an API for creating custom connectors. With this, you can connect to data sources unknown to AWS Glue.
Apache Nifi
Apache Nifi can connect to various data sources, including SQL and NoSQL databases, flat files, and others. It has a number of components for data extraction and loading called processors which you can drag in the Nifi canvas and configure.
Every Nifi processor for data access is available to you. You can check the Apache Nifi documentation for more details.
You can contribute new data sources and destinations to the сommunity. So, you need to know Java and follow the rules of the community in contributing code.
Skyvia
Skyvia offers more than 180 connectors, and more to come very soon. It supports connectors for CRMs, accounting, email marketing, e-commerce, human resources, marketing automation, payment processing, product management, all major databases and DWH, flat files, and more. It’s also not a problem whether your data is on-premise or in the cloud.
You can access your on-premise data with peace of mind using the Skyvia Agent. It allows you to connect to databases like SQL Server, MySQL, and more using an encrypted connection. You need to download the Skyvia Agent and install it. Then, download a secured key file and place it in the same folder as the Agent. The Agent is like an unbreakable metal door, and you use the key file to open that door to your on-premise data. You can also set it up so that Skyvia can access only the resources you specify and nothing else.
Customers can also leave a request for a new data connector. And Skyvia will prioritize building it without additional payment.
Transformation
AWS Glue
AWS Glue can generate ETL code to transform source data into target schemas. Its graphical user interface (GUI) supports various types of transformations. These include handling missing values, filtering, mapping, aggregating, pivoting, and more.
If you prefer to code your transformations, AWS Glue supports Python and Scala.
Apache Nifi
Apache Nifi transformation capabilities include aggregating, splitting, data encryption, and decryption to hide sensitive information. You can also do XSLT transforms for XML data and JOLT transforms for JSON data. Besides that, you can also do regular expressions and even run SQL commands in relational databases.
All transformations in Apache Nifi are part of its Processors list. So, check specific transformation processors in the Apache Nifi documentation.

AWS Glue also has Always Free AWS Glue 1 Million. It includes 1 million objects stored in the AWS Glue Data Catalog and 1 million requests/month.
Apache Nifi
The tool is free to use, from downloading to configuring. However, keep in mind that you'll have to pay for the planned infrastructure later on. There is no difference whether you'll build your own data centers or use cloud services.
There are also companies offering consulting services and even freelancers who have successful implementations experience, but they also require payment.
So, if you need to get the fast result it will be better to use alternatives that provide quick solutions. Apache Nifi, however, can offer you a flexibility for complex scenarios.
Skyvia
Skyvia Data Integration is a freemium tool with an option to request a 14-day trial. So, price is not a barrier to entry.
And when you’re ready, paid plans start from $19 per month. Pricing tiers depend on a few factors. It includes the number of loaded records, scheduling frequency, and advanced ETL features. There are no sale commitments. And customers can upgrade or downgrade at any time. Check out a detailed comparison here.
