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 Airflow
Apache Airflow is a free, open-source platform for developing batch-oriented workflows. It launched in 2014 and has big-name companies like Airbnb, Lyft, and Etsy in its portfolio. It has a growing community of over 2,000 contributors and many users worldwide.
Apache Airflow uses a workflow management system. This system handles automating and monitoring data integration processes. It can handle simple data transfers and complex machine-learning workflows. The user interface is easy to use, so you can focus on your work instead of minding a confusing interface.
But having that simple interface has a caveat. Open-source platforms need technical expertise, and Airflow is no different. You can start with several options to install. If you don’t want to hire experts to do this for you, you need to know about Python and some required libraries and even about Docker Containers for a seamless cloud deployment.
Apache Airflow also doesn’t have a record of privacy and security certifications, but it has security features like role-based access control and encryption. So, your data is safe from prying eyes. It also provides logging and auditing capabilities. So, this will help identify and investigate any security or privacy incidents. Companies with stringent security and privacy requirements trust Apache Airflow. But again, either you need some more technical expertise, or pay for someone who knows how to secure Airflow in your environment.
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 Airflow
Apache Airflow provides 80+ built-in data connectors and provider packages. These connectors will work with various types of data sources. And this includes databases, cloud platforms, and messaging systems. It can also deal with popular APIs, data warehouses, and lakes. Some of the most popular connectors include MySQL and PostgreSQL.
But, if you need one that is not available, you can create your own using Airflow’s API. Additionally, the Airflow community never stops developing and sharing new connectors. So, if your data source is so unique and recent, look for a connector in the community first. But if nobody made one for it yet, prepare to roll up your sleeves and 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 Airflow
Apache Airflow provides a flexible way to handle data transformations. Airflow supports a variety of data transformation tasks. This includes data cleansing, aggregation, filtering, and enrichment. You can perform transformations using code-based approaches. So, if you prefer to click than code to perform transformations, this is not for you.
Airflow has a web, graphical interface for data transformations, but coding is always required. So, it supports programming languages like Python and SQL.
Skyvia
Skyvia is a full-featured ETL service that allows powerful data transformations. It is a no-code solution allowing data splitting, conversion, lookups, and many more.
You can use the Skyvia Data Flow and Control Flow for advanced data pipelines. Transformations for these advanced pipelines are flexible.

Pricing
AWS Glue
AWS Glue pricing depends on the number of Data Processing Units (DPUs) used per hour. DPUs are a measure of processing power and memory capacity. AWS Glue charges $0.44 per DPU hour. This means you pay only for what you use with no upfront costs or commitments.
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 Airflow
Apache Airflow is an open-source platform, which means it’s free to use. There are no hidden charges or fees to access and use Airflow’s core features.
Moreover, Apache Airflow doesn’t need any upfront payment, subscription, or contract. Users can download, install, and run the software. They can do that on their own hardware or cloud infrastructure. They have full control over their deployment, scaling, and maintenance. This makes it an attractive option for those who want to avoid vendor lock-in.
There are also no user, workflow, or data source limitations in using Airflow. You can experiment, innovate, and collaborate on your pipelines without worries.
But this flexibility needs a lot of skilled work hours. So, if you need a data integration tool that is ready to use from day 1, this may not be an attractive option.
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.
If you doubt the price is worth it, check out review sites like G2. Aside from ease of use, reasonable pricing is one of the things Skyvia customers like. So, you can be sure the features you get are worth every penny.
