Azure Storage Services Flashcards
T or F
With storage accounts in Azure a unique namespace is created
True
T or F
No two storage accounts can have the same name
True
T or F
Azure Storage always stores multiple copies of your data so that it’s protected from planned and unplanned events
True
Redundancy ensures what for your storage account
that it meets availability and durability targets even in the face of failures
Redundancy in the primary region
storage account is always replicated 3 times
What are the two options for how your data is replicated in the primary region?
LRS - locally redundant storage
ZRS - zone redundant storage
LRS - local redundant storage
replicates your data 3X within a single data center in the primary region
provides 11 nines of durability (99.999999999%) over a year
T or F
LRS is the lowest cost redundancy option and offers the least durability
True
T or F
LRS is good for drive failures but lacks when it comes to a fire or flooding event
True.
All data may not be unrecoverable in the even of a fire or flooding
T or F
Zone redundant storage replicates your Azure Storage data synchronously across three Azure availability zones in the primary region
True
What’s the durability rate for ZRS in a given year?
12 nines.
99.9999999999%
How many availability zones does ZRS replicate your data to?
three
T or F
With ZRS your data is still accessible for both read and write even if a zone becomes unavailable.
True
T or F
Microsoft recommends using ZRS for primary regions for scenarios that require high availability
True
T or F
If you chose to have your data copied to the second region, it will be durable even in the event of a catastrophic failure
True
T or F
the secondary region is based on Azure Region pairs and can’t be changed
True
What are the two storage options for secondary regions?
geo redundant storage (GRS) - similar to LRS
geo zone redundant storage (GZRS) - similar to ZRS
GRS
copies data 3X in primary region then copies data to a single physical location in secondary region
GZRS
data is copied 3X across 3 availability zones in primary region & is also replicated to secondary region, using LSR for protection
Read accesses to data in GRS and GZRS
read only
Azure Storage platforms
Azure Blobs
Azure Files
Azure Queues
Azure Disks
Azure Tables
Benefits of Azure Storage
Durable and highly available
Secure
Scalable
Managed
Accessible
Azure Blobs
object storage solution.
store massive amounts of data
no restrictions to the type of data it can hold
can be reached from anywhere with an internet connection via HTTP or HTTPS
Blob storage is ideal for
serving images or documents directly to browser
storing files for distributed access
streaming video and audio
storing data for backup and restore, disaster recovery, and archiving
storing data for analysis by an on premises or Azure hosted service
Access tiers for Blob
Hot access - regularly accessed
cool access - infrequently access and stored for at least 30 days
cold access - infrequently accessed and stored for at least 90 days
archive access - rarely accessed and stored for at least 180 days with flexible latency requirements
Azure Files key benefits
shared access
fully managed
scripting and tooling
resiliency
familiar programmability
Azure Queues
service for storing large numbers of messages.
can be accessed from anywhere in the world via authenticated calls using HTTP or HTTPS
Azure Disks
block level storage volumes managed by Azure for use with Azure VMs
Azure Tables
store large amounts of structured data
NoSQL datastore that accepts authenticated calls from inside and outside the Azure cloud
Azure Migration
helps you migrate from an on premises environment to the cloud
Azure Migrations provides the following
Unified migration platform
range of tools
assessment and migration
Integrated tools for Azure Migrate
Discovery and assessment
Server migration
Data Migration Assistant
Migration Service
Azure App Service migration assistant
Azure Data Box
Azure Data Box
physical migration service that helps transfer large amounts of data in a quick, inexpensive, and reliable way
AZCopy
command line utility that you can use to copy blobs or files to or from your storage account
Azure Storage Explorer
standalone app that provides a graphical interface to manage files and blobs
Azure File Sync
a tool that lets you centralize your file shares and keep flexibility, performance, and compatibility
Which tool automatically keeps files between an on premises Windows server and an Azure cloud enviornment?
Azure File sync
Which storage redundancy option provides the highest degree of durability, with 16 nines of durability?
Geo-zone-redundant-storage
Which Azure storage service supports big data analytics, as well as handling text and binary types?
Azure Blobs
