Google Cloud Storage Options
There are several storage option available: structured, unstructured, transactional, and relational.
Cloud Storage. It is an object storage, which means the data stored as a packaged object in the form of data, its relevant metadata (date created, author, resource type), and permission. These keys will be available in the form of URL. There are four primary storage classes within cloud storage
frequently accessed which is great for data that’s stored for only brief periods of time.
nearline storage (once per month) usually used for backups
coldline storage (once 90 days) usually used as archive and disaster recovery
archive storage (once a year)
Cloud SQL. It supports relational databases, including MySQL, PostgreSQL, and SQL Server as a service.
Cloud Spanner. It is a relational database which strongly consistent and use SQL dialect. It suits the use cases of relational database management system with joins and secondary indexes with high availability and consistency when the data sizes exceeds 2 terabytes and serve high numbers of input and output operations.
Cloud Firestore. It is horizontally scalable, NoSQL cloud database. The data is stored in documents and then organized into collections.
Cloud Bigtable. It is NoSQL big data database service. It can handle high workloads at consistent low latency and high throughput, so it’s a great choice for both operational and analytical applications. It is good to be used with working with more than 1TB of semi-structured or structured data. Typically this is used to serve data to applications, dashboards, and data services.
