Azure Storage – Part 1

What is Azure Storage?

Azure Blob is a big scalable object of text or binary data

Azure Files are managed file shares for deployments

Azure Queues are messaging stores for secure communications between applications

Azure Table is schemaless storage of structured data (NoSQL) . Azure Tables have been replaced by CosmosDB

What is Azure Storage Account

Azure storage account is a container that groups all of the Azure services together. You manage your storage services all together as a group. If you delete a storage account you delete all of the storage services in it. Note that Azure SQL and Cosmos DB are managed separately and cannot be included into a storage account. Storage account name must be globally unique not just unique to your subscription.

What Settings to Choose?

When selecting Performance option you have a choice of Standard and Premium. This defines what disk storage will be used – a standard hard disk for Standard performance or a solid state drive for Premium. Premium is more expensive and faster but it only supports Page Blobs ( files up to 8 TB in size ). If you want any other types of storage services choose Standard

Account kind is recommended to be set to Storage V2. It is more expensive than Storage (general purpose v1) but it supports all features. Blob Storage option only support Blob Storage therefore if you want to use Azure Queues or other services inside your storage account do not choose Azure Blob.

Replication option – at a minimum Azure will always have a copy of your data within the data centre. This is called LRS (locally redundant storage). This
guards against hardware failure but it does not gurad agains an even if something happends to the datacentre. You can upgrade to
geo-redundant storage (GRS) and ger replication in other datacentres across the world.

Access tier defines how quickly you can access your storage. Cold storage is less expensive and suitable for the data that doens’t need to be retrieved very often. Choose hot storage if you need to get to your data often and fast.

For security purposes you can set the access to your storage to be provided only via HTTPs; you can also set inbound access requests only from the virtual network(s) you specify in Virtual Networks settings.
