GCP Storage 101

- Use cases: - website content - storing data for archiving and disaster recovery - distributing large data objects to users via direct download - Scalable to exabytes - Time to first byte in milliseconds - Very high availability across all storage classes - Single API across storage classes ## Signed URLs - Valet key access to buckets and objects via ticket: - crytographically signed URL - time-limited - operations specfied in ticket: HTTP, GET, PUT, DELETE (not POST) - any user with URL can invoke permitted operations - Example: - ``gsutil signurl -d 10m path/to/privatekey.p12 gs://bucket/object`` ## Strong Global Consistency - read-after-write - read-after-metadata-update - read-after-delete - bucket-listing - object-listing - granting access to resources ## Choose among Cloud Storage classes   ## Cloud Bigtable - Fully managed NoSQL, wide-column database service for terabyte applications - Accessed using HBased API - Native compatibility with big data Hadoop ecosystems - Managed, scalable storage - Data encryption in-flight and at rest - Control access with IAM - Bigtable drives major applications such as Google Analytics and Gmail ## Cloud SQL - managed RDBMS - offers MYSQL and PostgreSQLBeta databases as a service - automatic replication - managed backups - vertical scaling (read & write) - horizontal scaling (read) - google security - enable binary logging to use point-in-time recovery but it may slightly affect write performance ## Cloud Spanner - horizontally scalable RDBMS - strong global consistency - managed instances with high availablity - SQL queries - ANSI 2011 with extensions - automatic replication ## Cloud Datastore - designed for application backends - supports transactions - includes a free daily quota # Comparing Storage Options   # Decision Flowchart
