Azure Storage

Storage V2 (general purpose v2):
 Can contain blobs (including Azure VM disks), tables, queues, files Supports performance tiers: Standard and Premium
 Supports access tiers: hot, cool, archive

Storage Account Endpoints

Intermediary mapping with asverify:
 Step 1. Prepend asverify to your own CNAME record. This allows Azure to recognize your custom domain.

 Step 2. Modify the DNS record for the domain.

 Transaction costs: increases as the tier gets cooler.

 Geo-Replication data transfer costs (per GB): for GRS and RA-GRS storage accounts.

Standard and Premium Storage Accounts

 Blob Storage - specialized
for storing unstructured
object data
✔ You can easily upgrade a general-purpose v1 or Blob storage account to a general-purpose v2 account with no downtime and without the need to copy data


blobs.contoso.com	contosoblobs.blob.core.windows.net

 Step 2. Modify the DNS record for the domain.

 This methods eliminates downtime.

 Geo-Replication data transfer costs (per GB): for GRS and RA-GRS storage accounts.

 Outbound data transfer costs (per GB): transferred out of an Azure region
 Changing the storage tier:
 Changing the account storage tier from cool to hot incurs a charge equal to reading all the data existing in the storage account.

Demonstration – Storage Explorer

 Download and install Storage Explorer Connect to an Azure subscription
 Attach an Azure storage account

Locally Redundant Storage

Geo-Redundant Storage

Copies:
 Total of 6, with 3 per Azure region.

Zone Redundant Storage

Copies:
 3 across different Azure facilities in separate zones in the same region.

 ZRS does not support Azure VM disk files

Data Replication Overview

Locally-redundant Storage

Replication
		Data is replicated three time within a single facility in a single region.

 Maintains three copies of your data at a single facility All copies of the data exist within the same region Use if data can be easily reconstructed
 Use if there are regional governance requirements Low-cost option

	Copies	Strategy

	Maintains six copies of your data.	Data is replicated to a secondary geographic location and provides read access to your data in the secondary location.

Import and Export Service

Transfers very large amounts of data between on-premises and Azure:
 Import. Securely transfers data to Azure Blob storage (block and page blobs) and Azure Files. You ship hard drives containing your data to an Azure data center.

How CDN Works

Azure content caching service:
 Designed to expedite delivery of audio, video, images, etc. hosted by Azure services
 Utilizes the following data flow:
 1. Alice requests a file using a URL pointing to a CDN location. DNS routes the request to the optimal POP
 2. If edge servers do not have the file cached,

CDN Profile
A collection of CDN endpoints with the same:

 Pricing tier and provider:  Premium Verizon  Standard Verizon  Standard Akamai

CDN TTL can be:
 Included in cache-directive headers in the HTTP response from the content origin
 Determined by Cache Expiration Duration, configurable by using:  Global caching rules: affect all requests to the endpoint
 Custom caching rules: match paths and file extensions
 Custom caching rules override global ones

Lesson 04: Monitoring Storage

 Blob Container Count  Blob Count  Transaction metrics are available at:  account level

Alert Rules

whenever the Used Capacity is over 1000000 bytes.

 2. Define alert details, including:
 Alert rule name, description, and severity. There are five severity levels, Severity 0 to Severity 4.

 Automation Runbook

The latest metrics alerts offer: Improved latency
 Support for multi-dimensional metrics More control over metrics conditions
 Combined monitoring of multiple metrics Metrics from Logs (limited public preview)

Activity Log

 Viewed in the Azure portal.

 Forwarded to Log Analytics.

 Administrative  Security  Service Health  Alert  Recommendation Policy  Autoscale  Resource Health

 Keep activity logs for longer than the default of 90 days.

 View operational activities aggregated by status.

Collect Across Subscriptions

You can collect Azure Activity Logs into a Log
Analytics workspace using the Azure Log Analytics Data Collector connector for Logic Apps
 This facilitates using a workspace in a subscription that has a different Azure AD tenant
 It offers a number of advantages, including:
 Low latency, since the Azure Activity Log is streamed into the Event Hub
 Serverless services, with no infrastructure components to deploy
 Minimal custom code
