Module 7 - Configure Storage accounts Flashcards
Explore azure storage services
A service that you can use to store files , messages , tables and other types of information.
Azure containers: A massively scalable object store for tex and binary data
Azure Tables : Ideal for storing structured , non relational data
Azure queues -
Azure files -
Determine storage accounts Kinds
All storage accounts are encrypted using storage
Storage account
Standard general purpose v2 - Most scenarios including blob file , queue , table and data lake storage
Premium block blobs - Block blob scenarios with high transactions rates , or scenarios that use smaller objects or require consistently low storage latency
Premium file shares - Enterprise or high performance file share apps
Premium page blobs - High performance page blob scenarios
Determine replication strategies
Single region
LRS -
-Three replicas , one region
- Protects against disk , node , rack failures
- Write is acknowledge when replicas are committed
- superior to dual parity RAID
ZRS
- Three replicas , three zones , one region
- Protects against disk , node , rack failure and zone failures
- Synchronous writes to all three zones
Multiple regions
GRS
- Six replicas , two regions
- Protects against major regional disasters
- Asynchronous copy to secondary.
RA-GRS
- GRS = read access to secondary
- Separate secondary endpoint
- Recovery point objective delay to secondary can be queried
GZRS
- six replicas , 3+1 zones , two regions

Access Storage
Every object has a unique URL address - based on account name and storage type.
Container service : https://mystorageaccount.blob.core.windows.net
Table service:
if you prefer you can use your custom domain name
Secure Storage endpoints
Firewalls and virtual networks restrict access to storage accoubt from specific subnets on virtual network or public ip
Subnets and virtual networks must exist in the same azure region or region pair as storage account
