Storage > Disk is a centralized location for adding and deleting storage to your cloud. Disks are organized by disk name, disk and cloud type, zone and size.
- Disk Name is a unique name given to a disk for identification.
- Disk Types are differentiated by the various features of the disk.
|Disk Type ($)||Information||Recommendation|
|Magnetic||Cost effective, light or burst I/O, Shared among cloud customers so performance varies||Use for standard storage when performance is not important|
|General Purpose (SSD)||Faster than disk storage, Can handle high burst I/O for extended period of time||Good for small – medium databases|
|Provisioned IOPS||Great for I/O intensive workloads, allows to dedicate IOPS which is guaranteed by the cloud provider to ensure a certain speed of operations||Great for large databases and I/O intensive applications|
|Standard Persistent Disk||Standard HDD persistent disks are efficient and economical for handling sequential disk access operations, but are not optimized to handle high rates of operations.||Use for standard storage when performance is not important|
|Persistent Disk SSD
|Persistent disks perform in a predictable manner and scale linearly||Use when there is high rate of read/write operations|
- $: please note that your cloud provider could have varying rates for disks
- Cloud types are Amazon and Microsoft, at present. Disks in a particular cloud type are usually connected by means of a network with Compute instances on the same cloud type.
- Zone refers to the location of the data center where the data is stored. Some factors that govern selection of zone are –
- Legal – Countries can request data to be shared for law and order purposes. They could have restrictions on where certain data could be stored for users from their country.
- Performance – Creating Disks in proximity to Compute and Network zones could be helpful for delivering better performance, in general.
- Size refers to their capacity in GB.
