Storage rightsizing and data lifecycle management
Key role(s)
Objectives
Make the practice of storage rightsizing continuous and implement data lifecycle management.
Benefits
Regularly resize the infrastructure and remove unnecessary data for better IT efficiency.
As far as storage is concerned, optimisation opportunities must also be analysed on an ongoing basis, always based on the performance/cost trade-off.
Choosing the right type of storage:
| Storage Type | Description |
|---|---|
| Block Storage | Storage on disk |
| File Storage | Service of "File System" accessible via API |
| Object Storage | Storage of objects for frequent use |
| Archive Storage | Storage of archived objects (occasional use) |
For example, for the static content of a website, we do not choose disk storage but we prefer object storage.
Choose the right disk size and options.
| Type | Sizes | Options |
|---|---|---|
| HDD | 1GB-1TB | IOPS Optimized |
| SSD | 1 Go-4 TB | Throughput Optimized |
| 500GB-16TB | IO max | |
| 4TB-16TB | Max flow | |
| ... | redundancy level. | |
| ... |
And then of course define the life cycle of the data, taking into account the type of data, be it content, logs, backups etc.
