Azure Storage Flashcards
What is Azure Storage
Azure provides many ways to store your data
What are the four Azure storage service
Azure Blobs, Azure Files, Azure Queues, and Azure Tables
What is a storage account
A storage account is a container that groups a set of Azure Storage services together
What happens when a storage account is deleted
Deleting the storage account deletes all of the data stored inside it.
Storage account settings
A storage account defines a policy that applies to all the storage services in the account
What settings are controlled by storage account
Subscription location performance replication access tier secure transfer required virtual network
Subscription
The Azure subscription that will be billed for the services in the account.
Location
The datacenter that will store the services in the account.
Performance
Determines the data services you can have in your storage account and the type of hardware disks used to store the data. Standard allows you to have any data service (Blob, File, Queue, Table) and uses magnetic disk drives. Premium introduces additional services for storing data. For example, storing unstructured object data as block blobs or append blobs, and specialized file storage used to store and create premium file shares. These storage accounts use solid-state drives (SSD) for storage.
Replication
Determines the strategy used to make copies of your data to protect against hardware failure or natural disaster. At a minimum, Azure will automatically maintain three copies of your data within the data center associated with the storage account. This is called locally-redundant storage (LRS), and guards against hardware failure but does not protect you from an event that incapacitates the entire datacenter. You can upgrade to one of the other options such as geo-redundant storage (GRS) to get replication at different datacenters across the world.
Access tier
Controls how quickly you will be able to access the blobs in this storage account. Hot gives quicker access than Cool, but at increased cost. This applies only to blobs, and serves as the default value for new blobs.
Secure transfer required
A security feature that determines the supported protocols for access. Enabled requires HTTPs, while disabled allows HTTP
Virtual networks
A security feature that allows inbound access requests only from the virtual network(s) you specify
How many storage accounts do you need?
The number of storage accounts you need is typically determined by your data diversity, cost sensitivity, and tolerance for management overhead.
Storage name
Each storage account has a name. The name must be globally unique within Azure, use only lowercase letters and digits and be between 3 and 24 characters.
