What two kinds of storage accounts can you name?
General purpose
Blob (hot and cold)
What is a blob storage?
Large amounts of unstructured data in form of files that typically reside in containers. Each blob can be in 100s of GBs.
What is a block blob?
Block blobs are optimized for uploads and downloads. To accomplish this optimization,
Azure divides data into smaller blocks of up to 100 megabytes (MB) in size, which subsequently
upload or download in parallel. Individual block blobs can be up to 4.75 terabytes (TB) in size.
What is a page blob?
Page blobs are optimized for random read and write operations. Blobs are accessed as
pages, each of which is up to 512 bytes in size. When you create a page blob, you specify the
maximum size to which it might grow, up to the limit of 8 TB.
What is an append blob?
Append blobs are strictly for append operations because they do not support
modifications to their existing content. Appending takes place in up to 4 MB blocks—the same size as
the individual blocks of block blobs.
What is table storage?
Store partially structured data in tables without the
constraints of traditional relational databases. Each property consists of a name and a value.
What is queue storage?
Provides temporary messaging store. Developers frequently use queues
to facilitate reliable exchange of messages between individual components of multitier or distributed
systems. Message up to 64 KB in size.
What is File Storage?
Allows you to create SMB file shares in Azure just as you would with an on premises
file server. Files up to 1 TB in size. Max size of File Shar is 5 TB.
What is egress traffic?
Out of the Azure region where the storage account resides
How are storage services partitioned?
1 blob = 1 paritition
Table storage: 1 partition = entities with same partition keys
Queue storage: 1 queue = 1 partition
Storage account encryption
Once you enable it, Azure Storage services automatically encrypt any data during storage
account write operations and decrypt it during read operations. Microsoft manages the encryption
keys
What is a shared access signature SAS?
Limit access to blob containers,tables, queues and file shares only. Or narrow down to blobs, files, table entities. Also can specify the set of operations that are permitted on these resources. Validity can be restricted by start and end date. Access only from designated IP address. Enforce HTTPS connection. It is a URI signed with the storage account key. If you want to revoke it, key must be regenerated :(.
What is shared access policy?
Define policy (similar to SAS). Generate the SAP Uri that inherits the properties. To revoke, delete the policy only.
What is storage account diagnostic info retention policy?
7 days, can be set to 1-365 days
How to get 99.95% SLA in Cloud Service
Create at least 2 instances of worker and web role. Instances in same role run in separate fault domain and in separate upgrade domain.
Cloud Service Definition .csdef
Defines the service model, including the number of roles
Cloud Service Configuration .cscfg
Provides configuration settings for the cloud service and individual roles, including the number of role instances.
Cloud Service Package .cspkg
Contains the application code and configurations and the service definition file
ARM Template Create multiple instances
Add copy element to the resource type, specify number of iterations. 1-800. Creates in paralel order is not guaranteed. Must use copyIndex() as part of the name of the resource
ARM Template conditional creation
add condition element with [equals(parameters(‘newOrExisting’),’new’)]
What is OMS
OMS operates as a webservice which interacts with a number of distinct components which provides data collection, analysis and visualization.
Monitored systems can be on premise, azure or another cloud provider
OMS pricing models
Per functionalities or per nodes.
What is the default TTL on Azure CDN?
7 days
What are the origin types for a CDN
Storage, Cloud Service, Web App, Custom origin
CDN how long it takes to propagate by provider?
90 minute with Verizon and couple of minutes with Akamai.
Create CDN profile in powershell?
New-AzureCdnProfile -ProfileName -ResourceGroupName -Sku -Location
