Google Cloud Platform offers a variety of cloud database tools and services based on the needs of a company. As a result, the numerous instruments each have a distinct purpose.

In this article, we will cover the Google Cloud Database Services/Tools that provide SQL support in some fashion.

  • Cloud SQL

Cloud SQL is a fully-managed database service provided by Google Cloud Platform. It allows you to create, configure, and use relational databases hosted in the cloud. Cloud SQL supports popular database engines such as MySQL, PostgreSQL, and SQL Server.

With Cloud SQL, you do not have to worry about the underlying infrastructure, as Google Cloud Platform takes care of database provisioning, management, and maintenance tasks, including backups, updates, and security.

You can connect to Cloud SQL databases from applications running on the Google Cloud Platform and from applications running outside of the Google Cloud Platform. Cloud SQL also supports features like replication, failover, and read scaling, which can help improve your database applications’ availability, reliability, and performance.

In addition to the standard SQL features, Cloud SQL also provides some additional features such as automatic failover, point-in-time recovery, and automated backups. These features make it easier to manage and maintain your databases and ensure they are highly available and reliable.

  • All important DBMS-related activities, such as cloud backups, replication, and encryption patches, are automated by Cloud SQL.
  • Based on your needs, you may quickly link your database systems to App Engine, Google Kubernetes Engine, and the Compute Engine, and the platform also allows you to deal with on-premise systems and data.
  • Highly secure.
  • Easily scalable.
  • Hassle-free setup.


When to Use

When the storage need is less than 10TB, cloud SQL is typically used. As long as it stays within this restriction, it conducts end-to-end relational database administration for all your systems.

  • Cloud Spanner

Cloud Spanner performs all of the functions of Cloud SQL while guaranteeing 99.999% uptime. Furthermore, it increases row consistency and improves performance significantly.

  • Cloud Spanner allows availability across several regions with significantly less downtime than four nines.
  • It shares data based on load and size; performance is improved.
  • The data is consistent across regions. This means that the updates are current and consistent no matter where the users are from or how many people are working on the database simultaneously.
  • You do not need to re-architecture or scale a granular instance after you have chosen it.
  • Automated scaling without any limits.
  • Available across the world at any time.
  • Simple experience and better performance.


When to Use

Cloud Spanner outperforms Cloud SQL in terms of performance and availability. Furthermore, unlike Cloud SQL, it has no storage restriction. So, if your infrastructure demands all this and more, Cloud Spanner is the way to go.


  • AlloyDB for PostgreSQL

AlloyDB is one of Google’s most recent products, apart from Cloud SQL and Spanner. The latter two are PostgreSQL-compatible, whereas AlloyDB is fundamentally a PostgreSQL database.

  • Compared to normal PostgreSQL, AlloyDB is 4x quicker for transactional workloads and 10x faster for queries. In fact, for transactional workloads, it is twice as fast as Amazon’s Aurora PostgreSQL.
  • It has 99.999% availability across all regions, just like Cloud Spanner.
  • The program also makes it simple to migrate legacy databases to the cloud. It attempts to make its infrastructure more open-source in this manner, removing difficulties like licensing and other constraints.
  • Furthermore, BigQuery must be integrated with Cloud SQL and Spanner for improved analytics. Users of AlloyDB will not have to do the same because the functionality is built in and readily available.


  • The technology outperforms Cloud Spanner, Cloud SQL, and Amazon’s Aurora PostgreSQL in terms of performance and efficiency.
  • A good fit for AI and machine learning systems.
When to Use

If your organization and infrastructure require a more open-source method of operation with optimal performance, efficiency, and functionality, AlloyDB is the Google product to use.

  • Bare Metal Solution for Oracle

A bare metal solution is necessary for organizations with specialized workloads that require highly sophisticated services but need help to exploit the traditional cloud. Google supplies approved equipment for these workloads and install it in data centers where cloud services are hosted.

This allows organizations to migrate to the cloud and utilize these high-intensive services integrated with standard cloud services.

  • Organizations can employ cloud services with as little as 2ms latency.
  • All main Oracle features, including database clustering, replication, and more.
  • The tool serves as a link between traditional on-premises systems and the cloud.
  • It also supports integration with services such as Ansible-Based Toolkit and Oracle Kubernetes Operator.
  • Organizations can easily migrate their outdated infrastructure to the cloud.
  • When accessing numerous services, there is very little latency.
  • Access to all Oracle capabilities, including RAC and RMAN.
When to Use

This solution is primarily relevant to organizations with Oracle-based infrastructures. It allows them to modernize their entire system by transferring it to the cloud. It would also assist businesses in avoiding vendor lock-in and allowing them to leverage functionality from several providers.

  • BigQuery

BigQuery was created to conduct analytics involving millions of rows. It is primarily used with Cloud SQL and Cloud Spanner for the same purpose, as they have limited analytical capabilities on such a large scale.


  • Natural language processing is possible with the help of integrations such as Data QnA and Analyza. This enables users to work with data from chatbots, spreadsheets, and other custom-built user interfaces.
  • BigQuery, like AlloyDB, incorporates Vertex AI. It also integrates TensorFlow, allowing organizations to develop custom AI/ML models of varying complexity using only SQL.
  • BigQuery is a critical component of Business Intelligence solutions, offering activities such as transformation, analysis, visualization, and reporting.
  • The application enables real-time data capture, analytics, and replication, allowing organizations to make faster decisions and improve their performance and efficiency.
  • All data analytics operations are centralized.
  • Capability to manage large-scale database-intensive data capture and analysis.
  • Real-time operations in various sectors.
When to Use

Large organizations that require real-time operations on petabytes of data can use the technology. Its integration with other Google Cloud Database technologies, like Cloud SQL and Cloud Spanner, provides a wide range of operations, from the most basic to the most complex.
