Astra is a Kubernetes application data lifecycle management service that simplifies operations for stateful applications. Easily back up Kubernetes apps, migrate data to a different cluster, and instantly create working application clones.
Astra offers critical capabilities for Kubernetes application data lifecycle management:
Create a protection policy for each of your apps
Migrate applications and data from one Kubernetes cluster to another
Easily clone an application from production to staging
Create on-demand snapshots and backups
Clone and back up across clouds
Identify the health of your apps
Supported Kubernetes deployments
Astra supports all applications running on your Kubernetes clusters. For GKE clusters, note that there is a known limitation with apps deployed from the Google Marketplace.
NetApp has validated some apps to ensure the safety and consistency of the snapshots and backups. Learn the difference between a validated app and a standard app.
No matter which type of app that you use with Astra, you should always test the backup and restore workflow yourself to ensure that you can meet your disaster recovery requirements.
How Astra works
Astra is a NetApp-managed cloud service that is always on and updated with the latest capabilities. It utilizes several components to enable application data lifecycle management.
At a high level, Astra works like this:
You get started with Astra by setting up your cloud provider and by registering for an Astra account.
You add your first Kubernetes compute to Astra. Astra then does the following:
Creates an object store in your cloud provider account, which is where backup copies are stored.
Creates a new admin role and Kubernetes service account on the cluster.
Uses that new admin role to install NetApp’s Trident on the cluster and to create one or more storage classes.
Astra uses Trident to provision persistent volumes for your apps.
At this point, you can add apps to your cluster. Persistent volumes will be provisioned on the new default storage class.
You then use Astra to manage these apps, and start creating snapshots, backups, and clones.
Note that Astra continually watches your compute for state changes, so it’s aware of any new apps that you add along the way.
There are two types of costs associated with using Astra: charges from NetApp for the Astra service and charges from your cloud provider for persistent volumes and object storage.
Astra offers three plans:
- Free Plan
Manage up to 10 apps for free.
- Premium PayGo
Manage an unlimited amount of apps at a rate of $.005 per minute, per app.
- Premium Subscription
Pre-pay at a discounted rate with an annual subscription that enables you to manage up to 10 apps per application pack. Contact NetApp Sales to purchase as many packs as needed for your organization—for example, purchase 3 packs to manage 30 apps from Astra. If you manage more apps than allowed by your annual subscription, then you’ll be charged at the overage rate of $0.005 per minute, per application (the same as Premium PayGo).
If you don’t have an Astra account yet, purchasing the Premium Subscription automatically creates an Astra account for you. If you have an existing Free Plan, then you’re automatically converted to the Premium Subscription.
When you create an Astra account, you’re automatically signed up for the Free Plan. You can upgrade to a Premium Plan at any time. After you upgrade, Astra starts charging you for all managed apps in the account. The first 10 apps don’t stay in the Free Plan.
Google Cloud billing
When you manage GKE clusters with Astra, persistent volumes are backed by NetApp Cloud Volumes Service and backups of your apps are stored in a Google Cloud Storage bucket.
Note that Astra supports all service types and service levels. The service type that you use depends on your Google Cloud region.
Microsoft Azure billing
When you manage AKS clusters with Astra, persistent volumes are backed by Azure NetApp Files and backups of your apps are stored in an Azure Blob container.
