![]() The words acknowledge, enjoy, welcome are synonyms for "appreciate". Antonyms are used to express the opposite of a word. Antonym definitionĪn antonym is a word, adjective, verb or expression whose meaning is opposite to that of a word. This avoids repetitions in a sentence without changing its meaning. Synonyms are other words that mean the same thing.

When using Azure Disks, these are added as data disks to the node VMs. Persistent volumes on the other hand are Kubernetes objects which can be implemented in Azure using Disks or Files. The only other option available for an AKS node OS disk is Managed which is an Azure Managed Disk that is not stored on the VM host and persists local state of the VM even after it is deallocated. To summarize, in the context of AKS cluster node OS Disk, Ephemeral OS Disks which are managed by Azure and can only be populated with Azure managed OS images are operating system disks stored on the VM host and does not persist local state of the VM if the node VM is rebooted. Thus you cannot use unmanaged OS with AKS. Local state of the node is persisted even if the node Virtual Machine/ Virtual Machine Scale Set Instance is deallocated.Ĭurrently, AKS provides a security-optimized host OS by default, but no option to select an alternate operating system. ![]() These are page blobs which are managed by Azure. Currently, you cannot bring your own image and create an ephemeral OS disk from it.Īzure Managed Disk which does not depend on the node Virtual Machine's host. Ephemeral OS Disks are Azure managed and can only be populated by Azure managed OS images. Note: Local state will not be persisted with ephemeral OS Disk if the node Virtual Machine/ Virtual Machine Scale Set Instance is deallocated. When a user does not explicitly request managed disks for the OS, AKS will default to ephemeral OS if possible for a given node pool configuration. Like the temporary disk, an ephemeral OS disk is included in the price of the virtual machine, so you incur no additional storage costs. This provides lower read/write latency, along with faster node scaling and cluster upgrades. However, since containers aren't designed to have local state persisted, this behavior offers limited value while providing some drawbacks, including slower node provisioning and higher read/write latency.īy contrast, ephemeral OS disks are stored only on the host machine, just like a temporary disk. Persistent Volumes when using Azure Disk are added as DataDisk resources.īy default, Azure automatically replicates the operating system disk for an virtual machine to Azure storage to avoid data loss should the VM need to be relocated to another host. As noted in the Volumes section, the choice of Disks or Files is often determined by the need for concurrent access to the data or the performance tier. You can use Azure Disks or Files to provide the PersistentVolume. A persistent volume (PV) is a storage resource created and managed by the Kubernetes API that can exist beyond the lifetime of an individual pod. Pods often expect their storage to remain if a pod is rescheduled on a different host during a maintenance event, especially in StatefulSets. Volumes defined and created as part of the pod lifecycle only exist until you delete the pod.
