GCP Service - Storage

GCP Service: Storage

Google cloud provides 3 main services for different storage classes 

• Persistent discs: For block storage

A persistent disc can be considered similar to a USB drive, which can be connected and disconnected from the system as and when required. It can also be compared to HDD and SSD, depending on the use case and requirement. Block storage can also be considered, as data is saved in blocks and doesn't rely on a single path like file storage. Each block is self-contained and thus manageable but costly.

• File Storage: Network file storage

File storage provides disc storage over the network. It is similar to the storage process when papers are kept in files and then a particular leaf is plugged based on requirements. Files are organized similarly in file storage; to retrieve a file, the path must be known.

• Cloud Storage: Object Storage

Object storage is a flat storage in which the files are broken and spread across hardware, hence all objects are at the same level. Object storage does not store all data in the same file and contains metadata, information about the file that is used for processing, and usability.

 

Google Cloud Storage has different storage classes. 

• Standard: The standard storage class is used for data that is frequently used.
• Nearline storage is used when data is needed only once every 30 days.
• Coldline: The coldline storage class is used when data is needed once every 90 days.
• Archive -When data is only needed once a year, the archive class is used.This class is used for data archiving, online backup, and disaster recovery.
