What is persistent disk in Google Cloud?
Persistent disks are durable network storage devices that your instances can access like physical disks in a desktop or a server. The data on each persistent disk is distributed across several physical disks.
How do I create a persistent disk in GCP?
- Go to the VM instances page.
- Check the box and click the name of the instance where you want to add a disk.
- On the VM instance details page, click Edit.
- Under Additional disks, click Add new disk.
- Specify a name for the disk, configure the disk’s properties, and select Blank as the Source type.
What are the two types of persistent disks?
Persistent disks can either be regular persistent disks, which could be HDD, or SSD’s. Local disks, which are not persistent are always SSD’s. Like you can read in the docs using local SSD’s only allow up to 3TB to be stored on the disks while the Persistent disks allow up to 64 TB.
Is local SSD and ephemeral?
With Local SSDs, your data is always encrypted with an ephemeral encryption key.
Which statement is true of persistent disks?
Which statement is true of persistent disks? Persistent disks are always HDDs (magnetic spinning disks).
Can persistent disk be attached to multiple instances?
You can attach an SSD persistent disk in multi-writer mode to up to two N2 virtual machine (VM) instances simultaneously so that both VMs can read and write to the disk.
Does Google have its own CDN?
Cloud CDN supports modern protocols originally developed at Google, like HTTP/2 and QUIC, to improve site performance for mobile users and/or users in emerging markets.
Why do we need persistent storage?
Persistence storage is necessary to be able to keep all our files and data for later use. For instance, a hard disk drive is a perfect example of persistent storage, as it allows us to permanently store a variety of data.
How many persistent disks can you attach to Google Compute Engine?
Your VM instance and persistent disk are located independent to each other. This is why you can attach one persistent disk to a VM instance at a time and once it is detached from that VM instance, you can attach it to another VM instance.
Can you share the persistent disk with all three instances?
No, this is not possible, as the documentation that you cited at the time of writing said (since updated): However, if you attach a persistent disk to multiple instances, all instances must attach the persistent disk in read-only mode.
Is EBS persistent?
EBS volumes persist independently from the running life of an EC2 instance. You can attach multiple EBS volumes to a single instance. The volume and instance must be in the same Availability Zone.
What is difference between CDN and cloud?
Cloud computing and CDNs are similar because they each serve content from geographically distributed servers. But this is where they vary: A CDN delivers content as quickly as possible, while cloud computing is based on flexibility, scalability and on-demand delivery of applications and data.
