What is Cloud SQL? Learn All The Features

Cloud SQL is a database service that is embedded with fully managed architecture. Its potential is to help set up & regulate all of the relational databases over Google Cloud. It embeds flexibility upon setting up database infrastructure after the application development aspects. In case you have databases that are being carried out within MySQL, PostgreSQL BETA, or SQL Server, you can conveniently consider shifting it onto Cloud SQL.

The businesses pay a considerable fee to Google Cloud to gain access to this database infrastructure potential. Cloud SQL takes the responsibility of managing databases with services such as migration, patching, and backup & recovery. Holding onto the database service, the business gets the ease of focusing upon collaboration and productivity while scaling the applications.

Hence, this article intends to help you learn the details associated with the functionality of Cloud SQL and its features. So, hold onto this article till the end to brush up on your knowledge about Cloud SQL’s potential.

Working Overview of Cloud SQL

A relational database within Cloud SQL has the potential of storing related data on priority. The establishment of the database represents tables and rows that consist of interrelated data items. The associated characteristics of the relational database within Cloud SQL include SQL & Data Integrity. 

Structured Query Language (SQL) is termed to be the primary interface that builds communication with all of the relational databases. Hence, it is important for use upon adding, updating, deleting, and extracting subsets of data whenever required. Data integrity, on the other hand, ensures balance upon accuracy, completeness, and consistency of data.

Google Cloud SQL supports both fully-managed as well as relational database infrastructure. The compatibility of Cloud SQL with relational database infrastructure revolves around three engines, which include MySQL by Oracle, PostgreSQL by Global Development Group, and SQL Server by Microsoft. Along with offering support and compatibility, Cloud SQL can also be a preferable alternative to all of these relational database engines. 

In case you intend to spend less time on managing the database and spend more of that time upon using it. Most of the applications that are running over App Engine, Compute Engine, and other Google Cloud services make use of Cloud SQL on priority to seek database storage.  

Cloud SQL offers quite a lot of services to ensure that you do not have to build your database infrastructure and manage it, all on your own. You can direct your attention and focus towards Cloud SQL and handle the necessary operations. Cloud SQL looks after network connectivity, high availability, backups, failovers, import & export, monitoring, logging, maintenance, and updates. 

All of these services altogether make Cloud SQL a considerable database management service of Google Cloud. But, you should keep in mind that Cloud SQL is not a database administration service or tool. It is because the administration tool for the database serves a different purpose.

The business continuity is assured with the integration of Cloud SQL, with secure and reliable services that are backed by an SRE team 24/7. The database provisioning aspects are automated to help save more time during operations. Apart from that, storage capacity management can also be automated to increase the capacity whenever there is a need. 

The developers with Cloud SQL insights are finding it easy to carry out database observability. Cloud SQL offers easy integration upon Google Cloud Services such as BigQuery or GKE and other applications for enhanced operations.

For connecting with the Google Cloud SQL sequences or instances, you can possibly make use of:

  • Google Apps Script
  • MySQL Client
  • SQL Workbench
  • Toad- For MySQL
  • App Engine- Java Apps, Python Apps
  • External Applications- The apps that make use of standard MySQL database drivers.

Google Cloud SQL Pricing

The pricing of Google Cloud SQL depends upon the instance type you choose, amongst SQL Server, MySQL and PostgreSQL. The pricing for MySQL & PostgreSQL consists of certain charges that are included within the final bill. The charges are CPU and Memory pricing, Storage & Networking Pricing, and Instance Pricing.

The CPU and memory pricing for MySQL and PostgreSQL instances are:

  • vCPUs have charges of $0.0413/vCPU/hour. For one year commitment, you will have to pay $0.03098 per vCPU per hour. And for a 3-year commitment, you will have to pay $0.01982 per vCPU per hour.
  • Memory has charges of $0.0070 per GB per hour. But with a one-year commitment, you will have to pay just $0.00525 per GB per hour. If you are taking up a 3-year commitment, then the pricing will be $0.00336 per GB per hour.
  • HA vCPUs have charges, $0.0826 per vCPU per hour in general. With a 1 year commitment, you will have to pay $0.06195 per vCPU per hour, and for a 3-year commitment, you will have to pay $0.03965 per vCPU per hour.
  • HA Memory charges are $0.0140 per GB per hour. With a 1 year commitment, you need to pay only $0.01050 per GB per hour, and with a 3-year commitment, you will have to pay $0.00672 per GB per hour.

The storage and networking pricing for MySQL and PostgreSQL instances are:

  • Storage pricing includes $0.170 per GB/month for SSD storage, $0.0.90 per GB/month for HDD storage, and $0.80 per GB/month for the backups.
  • HA Storage pricing includes $0.340 per GB/month for the SSD storage, $0.180 for the HDD storage, and $0.080 per GB/month for the backups.
  • For serverless export, you do not have to pay any charges until 1st February 2022. But after that, you will have to pay $0.01/GB upon the instance storage capacity.
  • Network ingress to cloud SQL is free.

If you intend to know more details and an in-depth breakdown of pricing for CloudSQL, then you can refer to this official pricing documentation by Google for the same.  

Functionality Features of Google Cloud SQL 

To help you better understand the potential of Cloud SQL, it is important for you to get an idea of the core features of Cloud SQL. The features as specified by Google are Cloud SQL for MySQL, Cloud SQL for PostgreSQL, and Cloud SQL for SQL Server.

   1. Cloud SQL for MySQL
