Storage
Cloud Storage
Object storage bucket. Any amount of data and retrieve any numer of time. Storing BLOB is ideal. Data stored is immutable, only new version or overwrite. Allows versioning. Access can be manged by IAM and ACL Lifecycle management policies to manage data, like removing old, controlling number of versions etc Directory sync enables VM directory sync
Types of Cloud Storage
- Standard : Frequently accessed data
- Nearline : Infrequent like once per month
- Coldline : Access once every 90 days
- Archive : Ideal for DR, accessed less than once year. Higher access cost.
Autoclass
Saves cost by moving infrequent data to lower cost storage Storage transfer service : Allow larger data transfer. Transfer Appliance : Hardware appliance to transfer data.
Filestore
NFS V3 compatible file share.
Cloud SQL
Fully managed Mysql, postgress SQL or SQL server - Automatic replication - data encrypted - Includes Network firewall
Alloy DB
A faster SQL compatible DB managed by google.
Cloud Spanner
SQL compatible Relational database. - Scales horizontally - Very consistent - SQL compatible - High IP operations
Firestore
No SQL database for mobile, web, IoT services. Data is stored in documents and organized in to collections.
Stored as key:value pair. No SQL queries to retrieve data.
Indexed by default
Data is cached and get updated when device is online.
Billing based on storage, queries, documents read
ACID transaction. Ensure entire transaction consistency
Bigtable
No SQL Bigdata DB service. Handles huge data volumes with lo latency Ideal for Operational and analytical applications Ideal if - more than 1 TB data - Data is fast throughput, or rapidly changing. - Time series or data with semantic ordering - Realtime processing of large data - Machine learning algorithm
Memory store (Redis)
- Managed redis
- In memory data service
| Option | Best for | Capacity |
|---|---|---|
| Cloud storage | Immutable blobs larger than 5mb. in buckets | Petabyts, 5TB biggest object |
| Cloud SQL | Full SQL, for webframe work or existing applications | 64TB |
| Cloud Spanner | SQL compatible, horizontal scaling. | Petabytes |
| Firestore | Massive scaling with real time query. Offline query support | Petabytes, max object size 1MB |
| Cloud Bigtable | Large amount of analytical data. No SQL | Petabytes |
