Azure Services Platform InfrastructureGetting StartedQuick TourQ&A

We’re running scale services now 2B Live Search queries/month 30B Live ID authentications/month 240B Messenger messages/month

We’re building to run your services $500 million per data center 10,000 servers/month

What’s in it for me?Suppose competitors A and B have similar systems to merge

flat files from their branch locations each night, and display aggregate results in web applications.

Both systems have an isolated operations cost (including administration, data management, computing, storage, security, power, and insurance) of $12,000/month.

The CIO at Company A is converting her system to cloud computing. It will take 3 months to implement, at a cost of $13,000/month.

Then her operations cost will drop to $1,000/month. Will she save money the first year?

A: 3 * $12,000 + 3 * $13,000 + 9 * $1000 = $84,000B: 12 * $12,000 = $144,000

Hypothetical savings = $60,000

StorageTables

Blobs

Queue

Windows Azure Storage

Blobs – Provide a simple interface for storing files and metadata for the file.

Tables – Provide structured storage. A

Table is a set of entities, which contain a set of properties.

Queues – Provide reliable storage and asyncdelivery of messages for an application.

Windows Azure Storage Concepts

http://<account>.table.core.windows.net/<table>

http://<account>.queue.core.windows.net/<queue>

Windows Azure BLOBs

BLOBs are for storing files

BLOBs consist of 1 or more blocks (of variable size you choose)

Blocks provide continuation (in case of network failures) for BLOB upload

Max block size <= 4 MB

Max BLOB size <= 50 GBContainers can be “Public Read” or

“Private”PutBlock… PutBlock… PutBlockListBlocks can go out of order and/or in

parallel

Windows Azure Queues

An Account can create many Queues

Queue contains unlimited number of Messages

Message is stored for at most a week

Message Size <= 8 KB (point to BLOB or Table for more)

When pulling a Message, specify InvisibilityTime

InvisibilityTime <= 2 hours

Messages should be IDEMPOTENT

Windows Azure TablesProvides Structured Storage

Massively Scalable Tables Billions of entities (rows) and TBs of data Automatically scales to thousands of servers as traffic

growsDurable

Data replicated at least 3 times (in different domains)

Familiar and Easy to use Programming InterfacesADO.NET Data Services and LINQ – .NET 3.5

SP1REST - with any platform or language

What tables can do

Table Data ModelTable

Each account can create many tablesJust insert into a master table called "Tables“ (per

account)

Data is stored in TablesA Table is a set of Entities (rows)An Entity is a set of Properties (columns)

Entity (row)Two “key” properties are together the unique ID of

the entity in the Table PartitionKey – enables scalability RowKey – uniquely identifies the entity within the partition

Partition Key And Partitions

Every Table has a Partition KeyIt is the first property (column) of your

TableUsed to group entities in the Table into

partitions—for physical storage optimization

A Table Partition All entities in a Table with the same

partition key value

Getting Started Example

Use Cases1. User: create workspace2. User: submit string3. User: get results4. User: delete record5. User: delete workspace

Requirements1. Employees at WorldWide Palindrome need to

reverse strings.2. They need a web page to submit strings to

Windows Azure and view results.

Fault domains are based on the topology of the data center

Statistical in nature

Update domains are determined by what percentage of your service you will take out at a time for an upgrade
