Study Notes
Google Cloud Storage Overview
- Google Cloud Storage is designed for object storage, best for unstructured data such as images, videos, and backups.
- It is not optimized for structured data, in-memory caching, or CPU-intensive workloads.
Block Storage vs. Object Storage
- Block storage, like Persistent Disk, supports operating system installations due to raw block-level access.
- Object storage cannot support OS installations, as it handles data at the object level rather than block level.
Google Cloud Storage Classes
- Archive Storage Class: Ideal for data accessed infrequently (once a year or less); suitable for long-term data storage such as compliance archives.
- Dual-Region Buckets: Provide increased durability and availability by replicating data in two geographic regions.
Access Control in Google Cloud Storage
- Fine-grained access: Enables setting different permissions for individual objects within the same bucket, accommodating varying user access needs.
- Uniform access does not allow for different permissions per object.
File Upload Commands
- Use the command
gsutil cp backup.zip gs://my-backup-bucket/to upload files into Google Cloud Storage buckets.
Bucket Locations and Latency
- Multi-region buckets: Optimal for global applications and reduce latency by storing data in multiple geographical locations.
- They ensure high availability and minimal latency for internationally distributed users.
Object Versioning
- Object versioning allows keeping multiple versions of an object for recovery purposes, crucial for restoring data after accidental deletions or overwrites.
Lifecycle Management Use Cases
- Lifecycle management can automate the deletion of old log files after a specific duration, enhancing data management and cost efficiency.
