Study Notes
Overview of Cloud Storage Services
- Cloud storage supports diverse use cases including website content hosting, data archiving, and distributing large files.
- Features include high scalability, low latency responses (milliseconds), and high availability across various storage classes.
- Accessing objects is done via URLs, and storage is organized in buckets rather than a traditional file system.
Cloud Storage Classes
-
Regional Storage:
- Offers cost-efficient storage yet confined to a specific region; suitable for frequently accessed data near compute instances.
-
Multi-Regional Storage:
- Geo-redundant with data stored in at least two physical locations, at least 100 miles apart; ideal for frequent access needs like website content or mobile applications.
-
Nearline Storage:
- Designed for infrequently accessed data, accessible at least once a month; low storage costs but associated retrieval fees.
-
Coldline Storage:
- Extremely low-cost and highly durable for archival and disaster recovery; accessible data is available within milliseconds, suited for access once a year.
Storage Infrastructure Characteristics
-
Buckets:
- Globally unique names required; buckets cannot be nested.
-
Objects:
- Can be of any file type; inherit the storage class of their bucket with no minimum size.
Management Commands and APIs
- Data access can utilize
gsutil
commands or JSON/XML APIs for integration with applications.
Storage Class Administration
- Default storage class assigned to new objects; classes can only be changed through object transfer between buckets.
- Object Lifecycle Management provides automation of storage class changes based on object conditions over time.
Access Control Mechanisms
-
IAM (Identity and Access Management):
- Allows granular control over bucket access for users and service accounts, inheriting roles through projects to objects.
-
ACLs (Access Control Lists):
- Offer precise permissions for buckets and objects, limited to 100 entries defining user scopes and permissions per entry.
Additional Features
-
Signed URL:
- Permits non-authenticated access to buckets within a designated time frame.
-
Object Versioning:
- Ensures object immutability; creates archived versions when objects are deleted or changed, identifiable by generation number.
-
Object Lifecycle Management:
- Manages rules for object retention and storage class downgrades, with rules evaluated asynchronously and updates reflecting within 24 hours.
-
Object Change Notification:
- Notifies applications of object updates via "watch" requests.
Data Transfer Methods
-
Data Import Services:
- Includes Transfer Appliance, Storage Transfer Service, and Offline Media Import for seamless data migration.
-
Transfer Appliance:
- A hardware tool enabling secure migration of large data volumes up to 1 petabyte to GCP without business disruption.
-
Storage Transfer Service:
- Facilitates high-performance import of online data from other sources like Amazon S3 or HTTP/HTTPS locations.
-
Offline Media Import:
- A third-party service that uploads data transferred via physical media.
True/False Statements Validation
- Successful object uploads enable immediate download availability and metadata operations (True).
- A successful deletion request will yield a 404 Not Found status for subsequent access (True).
Other GCP Data Services
-
BigQuery:
- Offers data warehousing services with an interactive SQL interface for data querying.
-
Spanner:
- A global data storage service that supports ACID transactions.
