| Context | |
| Google Cloud Storage (GCS) is a service for storing your objects in Google Cloud. An object is an immutable piece of data consisting of a file of any format. You store objects in containers called buckets. All buckets are associated with a project, and you can group your projects under an organization. GCS provides several storage classes that enable a consumer to choose the right balance of access frequency against cost. More frequently accessed storage has a higher storage cost but lower access charge, while less frequently accessed data has a lower storage charge and higher access charges. | |
| Decision | |
| Need for an immutable compliant storage on the cloud to store regulatory related files and encrypt using customer managed encryption key (CMEK). | |
| The storage solution must be simple, scalable and can be accessed through APIs. | |
| Usecases: - Media content storage and delivery. Geo-redundant storage with the highest level of availability. - Backups and archives. - durable storage for static websites. - Integrated repository for analytics and ML. | |
| GCS Object storage solution has a unique position with application transformation. GCS offers API level access on data storage for different storage requirements. GCS is tightly integrated with GCE, GKE, database services and git. | |
| It is recommend GCS Object storage as one of the storage solution options. | |
| Consequences | |
| Pros or Capabilities: | |
| Key Functional Capabilities for Google Cloud Storage can be found here. | |
| Cons or Service Limitations: | |
| The resource locations Organization Policy Service constraint controls the ability to create regional resources. When regional resource are created, testing should be carried out for new policy on non-production projects and folders. | |
| GCS Services explicitly to be used by Terraform Module for Prod/UAT and Development environment. | |
| Cloud Storage 5TB object size limit. Cloud Storage supports a maximum single-object size up 5 terabytes. If you have objects larger than 5TB, the object transfer fails for those objects for either Cloud Storage or Storage Transfer Service. | |

| Compliance | |
| Encryption At Rest | |
| All Cloud Storage data are automatically stored in an encrypted state, but you can also provide your own encryption keys. For more information, see Cloud Storage Encryption. | |
| Encrypt your Cloud Storage data with Cloud KMS | |
| Turn on uniform bucket-level access and its org policy. | |
| Enforce the domain-restricted sharing constraint in an organization policy to prevent accidental public data sharing, or sharing beyond your organization. | |
| Audit your Cloud Storage data with Cloud Audit Logging. | |
| Secure your data with VPC Service Controls. | |
