What is Google Cloud SQL?

Cloud SQL is a fully managed relational database for MySQL, PostgreSQL, and SQL Server.

It reduces maintenance cost and automates database provisioning, storage capacity management, replication, and backups. It offers quick setup, with standard connection drivers and built-in migration tools.

How Do You Set It Up?

Cloud SQL is easy to setup. You select the region and zone where you would like the instance to be, and it gets created there.

You also have a lot of configuration options, where you can select the machine type with the right number of CPU and amount of memory you need.

Choose storage each type between solid state and hard disk drives, depending on latency queries per second and cost requirements and set storage capacity.

Higher storage capacity leads to better performance.

What About Back Up?

Cloud SQL also offers automated backups and recovery options.

You can set time slots and locations for backups. For production applications, it is recommended to enable high availability, or HA.

By enabling this feature, the database instancewill automatically failover to another zone in your selected region in case of an outage.

You can also create cross-regional replicas to protect from regional failures.

In addition, you can enable automatic storage increase to add more storage when nearing capacity.

How Do You Migrate an Existing MySQL Database to Cloud SQL?

Cloud console makes it very easy by providing a migrate data button, which guides you through easy steps.

First, you provide your data source details, things like public IP address, port number,

and your replication credentials.

Second, you create a Cloud SQL read replica, just like we discussed in the creation process, using a SQL dump file.

Third, you sync the read replica with source. And, finally, you promote the read replica to primary instance with very low downtime.

Is Data Safe in Cloud SQL?

Like anything else in Google Cloud,the data in Cloud SQL is encrypted at rest and in transit.

External connections can be encrypted using SSL or Cloud SQL Proxy, which is a tool to help you connect to your Cloud SQL instance from your local machines.

You can use Cloud SQL as a relational database for your applications that are hosted within Google Cloud, like App Engine, Cloud Run, Compute Engine, Kubernetes Engine, or Cloud Functions.

You can also connect your Cloud SQL database with applications that are hosted outside of Google Cloud.

How Much Does It Cost and What Are Some Uses Cases?

Cloud SQL pricing varies depending on MySQL, PostgreSQL,or SQL Server.

Broadly speaking, though, it’s the combination of the type of instance, storage, or network you use. SQL Server also has some licensing costs.

Since Cloud SQL is a relational database, you can use it with any online transaction processing apps, such as order or payment processing apps, where you need to handle frequent queries with fast response times.
