+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.
