the associated Windows Azure account
 vm.pp – create a new virtual machine instance from a virtual machine
image
 vnet.pp – create a new virtual network

Example Modules
 Modules are just directories with files, arranged in a specific,
predictable structure
 Ala run list in Chef
 site.pp
include ntp
include apache

Storing Data
2 Examples:
 Azure Storage
 Table Storage

Windows Azure Storage
Storage in the Cloud
 Scalable, durable, and available
 Anywhere at anytime access
 Only pay for what the service uses
RESTful Web Services
 Use from Windows Azure Compute
 Use from anywhere on the internet

Azure Data Management

Storage Libraries in Many Languages

Setting up Storage
• Configure Your Application to Access Storage
• Download and use the Ruby azure package, which communicates with the storage REST
services.
• Use RubyGems to obtain the package
• Use a command-line interface such as PowerShell (Windows), Terminal (Mac), or
Bash (Unix).
• Type "gem install azure" in the command window to install the gem and
dependencies.
• Import the package
• Using your favorite text editor, add the following to the top of the Ruby file where
you intend to use storage:
• require "azure"

Storage Connection
• Setup a Windows Azure Storage Connection
• The azure module will read the environment variables
AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_ACCESS_KEY for information
required to connect to your Windows Azure storage account.
• If these environment variables are not set, you must specify the account
information before using Azure Storage Services with the following code:
Azure.config.storage_account_name = "<your azure storage
account>"
Azure.config.storage_access_key = "<your azure storage access key>"

Getting Storage Credentials
• To obtain the Account Name and Access Key values:
• Log into the Windows Azure Management Portal.
• Navigate to the storage account you want to use
• Click MANAGE KEYS at the bottom of the navigation pane.
• In the pop up dialog, you will see the storage account name, primary access key
and secondary access key. For access key, you can either the primary one or the
secondary one.

Table Storage

Azure Storage Concepts

Create a Container
azure_blob_service = Azure::BlobService.new
begin
container =
azure_blob_service.create_container("test- container")
#Optional – Set Container to public read acess
azure_blob_service.set_container_acl('test-
container', "container")
rescue
puts $!
End

Upload a Blob to a Container
content = File.open("test.png", "rb") { |file|
file.read }
blob =
azure_blob_service.create_block_blob(container.name,
"image-blob", content)
puts blob.name

List the Blobs in a Container
containers =
azure_blob_service.list_containers()
containers.each do |container|
blobs =
azure_blob_service.list_blobs(container.name
)
blobs.each do |blob|
puts blob.name
end
end

Download or Delete a Blob
#Download
blob, content =
azure_blob_service.get_blob(container.name,"
image-blob")
File.open("download.png","wb") {|f|
f.write(content)}
#Delete
azure_blob_service.delete_blob(container.nam
e, "image-blob")

Storing Data

Azure Storage
Table Storage

Table Storage Concepts

No Fixed Schema

Create a Table
azure_table_service =
Azure::TableService.new
begin
azure_table_service.create_table("testtable
")
rescue
puts $!
end

Add or Update an Entity
#Add
entity = { "content" => "test entity",
:PartitionKey => "test-partition-key",
:RowKey => "1" }
azure_table_service.insert_entity("testtabl
e", entity)

Update an Entity
#update
entity = { "content" => "test entity with
updated content",
:PartitionKey => "test-partition-key",
:RowKey => "1" }
azure_table_service.update_entity("testtabl
e", entity)

Process Groups of Entities
azure_table_service = Azure::TableService.new
batch =
Azure::Storage::Table::Batch.new("testtable",
"test-partition-key") do
insert "2", { "content" => "new content 2" }
insert "3", { "content" => "new content 3" }
end
results = azure_table_service.execute_batch(batch)

Query Entities
#Single
result =
azure_table_service.get_entity("testtable", "test-
partition-key",
"1")
#Multiple
query = { :filter => "PartitionKey eq 'test-
partition-key'" }
result, token =
azure_table_service.query_entities("testtable",
query)

Query a Subset of Entities
query = { :filter => "PartitionKey eq 'test-
partition-key'",
:select => ["content"] }
result, token =
azure_table_service.query_entities("testtable",
query)

Deleting
#Entity
azure_table_service.delete_entity("testtable",
"test-partition-key", "1")
#Table
azure_table_service.delete_table("testtable")
