Amazon Athena vs Azure Storage: What are the differences?

Introduction

In this article, we will discuss the key differences between Amazon Athena and Azure Storage. Both Amazon Athena and Azure Storage are popular cloud-based storage and analytics services. While they offer similar features, they have some distinct differences that make them suitable for different use cases. Let's explore these differences in more detail below.

1. Data Processing Approach: One of the key differences between Amazon Athena and Azure Storage is their data processing approach. Amazon Athena follows a serverless query engine design that allows users to run interactive SQL queries directly on their data stored in Amazon S3. On the other hand, Azure Storage provides data storage and retrieval capabilities but does not offer a built-in serverless query engine like Athena. Therefore, to process and analyze data stored in Azure Storage, users need to use additional services like Azure Data Lake Analytics or Azure Databricks.

2. Integration with Ecosystem: Another significant difference is the integration of these services with their respective cloud ecosystems. Amazon Athena is tightly integrated with the Amazon Web Services (AWS) ecosystem, which means it seamlessly works with other AWS services like AWS Glue, AWS Lambda, and Amazon Redshift. This integration allows for a more seamless data pipeline and leverages the capabilities of other AWS services. In contrast, Azure Storage is part of the larger Microsoft Azure ecosystem and offers seamless integration with several Azure services such as Azure Data Factory, Azure Databricks, and Azure Analysis Services.

3. Pricing Model: Pricing is another aspect where Amazon Athena and Azure Storage differ. Amazon Athena pricing is based on the amount of data scanned by the queries and the cost per terabyte for the storage. Users only pay for the queries they run, making it a cost-effective option for ad-hoc and on-demand analysis. In contrast, Azure Storage pricing is based on the amount of stored data and transactions, such as data writes and reads. This pricing model may be more suitable for scenarios where data storage and retrieval are the primary concerns.

4. Data Source Support: When it comes to data source support, Amazon Athena has broader support compared to Azure Storage. Athena can directly query data in Amazon S3, AWS Glue Data Catalog, and external tables defined in AWS Glue. It also supports various data formats like Parquet, ORC, JSON, and CSV. Azure Storage, on the other hand, can work with various data types such as blobs, files, queues, and tables, but additional tools and services are required for complex data transformations and analysis.

5. Managed Service vs. Cloud Storage: Amazon Athena is a fully managed service provided by AWS, meaning that AWS takes care of managing the infrastructure, scalability, and performance of the service. Users can focus on executing queries and analyzing results without worrying about managing underlying servers or clusters. In contrast, Azure Storage primarily provides cloud storage capabilities, and users need to provision and manage their own infrastructure if they want to perform analytics on the data.

In summary, Amazon Athena offers a serverless query engine for data stored in Amazon S3, tightly integrates with the AWS ecosystem, follows a pay-per-query pricing model, and provides broader data source support. On the other hand, Azure Storage is a cloud storage service that requires additional services for data processing and analytics, integrates with the Azure ecosystem, follows a different pricing model based on storage and transactions, and supports various data types.
