(hardware and software) that are delivered as a service over
a network (typically the Internet).

7. Test patterns
• Pass/Fail Patterns

• Simulation Patterns
• Stress-Test Patterns
• ….

21. Web Sites
• Easy to deploy
• No OS management
• Scaling
• Monitoring
• Publish from different source controls
• Support different technologies (PHP, node.js,
.NET)
• Low cost support – shared mode
• Reserved mode – dedicated instance
• Each site run in an isolated environment
22. Web Roles
• Used to host application composed from multiple tiers
• Each web-role is scalable independently
• In comparison with Azure Websites, a lot of custom
configuration can be done
• Network isolation
• Any kind of framework can be used in this machines
23. Worker role
• Perfect place to run long running task
• Can be used with success with web-roles for tasks that run in
background
• Cannot be used to host a web application
• In the moment when the “WHEN(TRUE)” ends the worker role
process stop
• Can be seen as a process that can execute a specific type for
an infinite period of time
24. Virtual Machine
• Can be used to install any kind of operating system from
Windows to Linux
• Build in support and images available for different versions of
Linux and Windows.
• Custom machines can be created with our own VHD
• Build in support for MongoDB, MySQL, Cassandra, certificates
• Migration from on-premise to cloud and cloud to on-premise
can be done using VHD

27. SQL Database
• Relational database based on SQL Server
• It is almost like SQL Server from on-premises
• BUT:
• We don’t have support for distributed transactions
• Each table have to contain at least one cluster index
• We cannot attaché a database
• We don’t have support for jobs
• Double check the total cost of a having a SQL Database –
there are a lot of times when we can use Table Storage
Service
28. Table Storage Service
• Store any kind of serializable data
• You don’t need any kind of complex data structure or
SQL knowledge.
• Is not a relational database
• In the same table you can have more than one type of
entity
• Each entity from can have maximum 252 properties + 3
default
• The maximum size of total tables cannot accede 100.000
GB (100TB)
• The maximum size of an entity can be 1MB
29. Windows Azure Blob Storage
• It is used when we need to store large amount of data
(0011100110)
• We can store: images, videos, backup data… any kind of
data
• Maximum size 100TB
• ETag – unique version of each blob. Is updated when
content is written to the blob
• The maxim size of a blob in emulator is 2 GB
30. Windows Azure Blob Storage
• Block blobs
• Support multi-upload of blocks in parallel
• When updating a block, the old version is not
override until you commit it
• Can be used for large files
• Page blobs
• Collection of pages of 512b
• Can be accessed by an offset
• Can be used when the content is changing very often
• We cannot change a block blob to a page blob or a page
blob to a block blob
31. Windows Azure Queues
• It is very similar with a named queue from
Windows
• You can update the message from a queue
• Operations: peek, insert, deleting, getting
• Remark: getting a message don’t remove the
message from queue
• Message is persisted until someone will consume
it
• Queue maximum size: 100TB
34. Hadoop
• When we need to analyze big data
• Logs, payment information from banks, M2M
data, historical information
• There is no relational database
• Hadoop Distributed File System
• Apache Open Source Project
35. How does the system works
• Microsoft
• Google
• Amazon
• Hewlett-Packard
• IBM
• CenturyLink/Savvis
• Verizon/Terremark
• Joyend
• Citrix
• Bluelock
• Vmware
• Rackspace
• Salesforce
36. Why we need another messaging
system beside
Windows Azure Queues?
37. Windows Azure Service Bus
• Microsoft
• Google
• Amazon
• Hewlett-Packard
• IBM
• CenturyLink/Savvis
• Verizon/Terremark
• Joyend
• Citrix
• Bluelock
• Vmware
• Rackspace
• Salesforce
38. More than a simple Queue
• Death Letter support
• Order of messages
• Duplicate messaging detection
• Transaction, Sessions
• Multi-distribution mechanism
• Filtering support
39. How does it work
• Microsoft
• Google
• Amazon
• Hewlett-Packard
• IBM
• CenturyLink/Savvis
• Verizon/Terremark
• Joyend
• Citrix
• Bluelock
• Vmware
• Rackspace
• Salesforce
41. Shared Access Signature
• Provide a method to offer access to different resources
from storage account
• You can provide access to resources without requiring a
user to authenticate
• It is a simple way to control and manage who have
access to your storage
• The base of this mechanism is a custom token
• You can add, remove and change a SAS at runtime
• Each policy is defined by a unique id
• The validity of a SAS can be limited (time base)
42. Windows Azure Caching
• Nice feature: you pay only the machine computation
• All the content is in the machine memory
• 2 types of caching:
• Dedicated roles
• Co-located roles (shared memory between application and
cache)
• Cache cluster support (only in combination with a storage account)
• Maximum size of a cache is 14 GB (limited by the memory size of
VM role)
• Each item can have an expiration date
• Built in support for storing web session in the cache
43. Caching Service
• Offer build in caching mechanism
• Can be accessed by anybody from anywhere
based on the namespace
• Maximum size is 4 GB
• Is more expensive than Windows Azure Caching
but can be accessed from any location
• This caching mechanism is offered as a service
• It is similar with Caching Server from on-premise
servers
45. Azure Access Control Service (ACS)
• Provide us a mechanism to authenticate users from
different identify providers: FB, Google, Y!, Live … even
custom identify providers and Active Directory (2.0+)
• Is based on a claim based authentication
• You never work with user credentials
• Depending on the provider, you can access different
information about user
• You don’t need anymore to implement a user
management mechanism
• BUT, if you need, you will need to define roles and
store user id’s
49. Media Services
• The based action that can be done is: content streaming
• Ingest – first step when content is uploaded (upload and encryption)
• Encoding – Process the media content (change the encoding,
converting and transform) – we can use only supported formats
• Protect – encryption of live streaming using a built-in mechanism
• Streaming – send content to consumers (even Apple HTTP Live
Streaming is supported)
• Support for CDN (Azure and 3th party CDN’s are supported).
• Supported devices: Android, iOS, ,Mac, Windows Phone, Windows 8,
X-box, embedded devices, dedicated devices
