Windows Azure Lifecycle

Design

-it isright tool for right purpose?

-scalability, reliability, availability

-Design for SCALE

-the cloud is about scaling out

-design for multiple instance

-HybridMode

-Which part is going to cloud

-Which part is remain on premise

-Define Roles

-WorkerRole

-WebRole

-VMRole

-Communicationand protocols

-WCF

-Choosestorage technology

-Consideration

-Diagnostic& Management

-Design for price

-Design for Scale

-Migration

-Nonsupport technology

-Storagearchitecture

-Statemanagement

-Caching

-Performance

-Connectivity

-Testing

-Regulations

Development

-VisualStudio

Deployment

-Staging

-Flow

-Buildapp on premise

-Deploy Storage to Cloud & Test

-Deploy Compute to Cloud & Test

-DeploymentApproach

-Package& Deploy

-config=> Fabric

-app=> Cloud

-Publish

-Production

Testing

-Emulator vs real Cloud different

-Type of testing

-SystemIntegration Testing

-UserAcceptance Testing

-functionality

-Stress test

-Recovery test

-Security test

Managemnt

-Portal

-Automaticallyvis API Rest Based

-Tools

-CSPack.exe

-Packageapp

-CSRun.exe

-Takepackage deploy and run

-CSManage.exe

-Allmanagement task

-e.g

-suspendservice

-deleteservice

-newdeployment

-rundeployment

-Powershellcmdlets

-azurecmdlets

-Upgrade

-Web Deploy vis IIS

-WebProject

-Fault& Upgrade domain

-Faultdomain

-Whenyour app down. Fabric controler : if have more than one instance

-Upgradedomain

-Whenyou upgrading. upgrade by upgrade domain

-VIP swap

-extenalIP and virtual IP

Windows Azure Storage

No-relational Windows Azure Storage

-Don't forcedata integrity

Relational Storage - SQL Azure Storage

Affinity group

Compute

Storage

Storage Security

Windows Azure Abstractions

-Blobs

-Account/Container/Blob/Pagesor Blocks

-Block

-Streaming

-Optimistic Concurrency via ETags

-Pages

-RandomAccess

-Optimisticor Pessimistic (locking) concurrency via leases

-Shared access signature

-CDN(Content Delivery Network)

-Files and large object

-Drive

-NTFSVirtual Hard Disk

-ExistingApplication

-Tables:entity, property

-PatitionKey

-same partition same server

-Entity Group Transaction

-Massively scalable structured storage

-Queue:FIFO,Communication channel, distribution mechanise

-Loosely Coupled Workflow

-Reliable Delivery

-Order not guarantee

-Poison Message

-Item puter operation

-Addaccount $500 ->NO

-Setaccount to $500 ->YES

-Reliabledelivery of message

Azure: Operation System for the cloud

OS -provides computing power => role

-information handling => storage

-information management => diagnostic

SQL Azure

-ApplicationTopologies

-CodeNear

-CodeFar

-Hybrid

-Architecture:scalable, reliable, available

-DatabaseReplics

-*3(disaster policy)

-Workingwith primary one

-Sharding,SQL Azure Federation

-Connect toSQL Azure via TDS (Tabular Data Stream) service

-Logic vsPhysical Administration

-Logical=> SQL Azure Focus on Logical Administration

-Schemacreation

-Queryoptimization

-Securitymanagement (login, user, role)

-Physical

-LoadBalance

-Failover

-Automaticallyprovide HA

-Affinity group

-Sync

-viaMSF - microsoft sychonazation framework

-Onpremise <-> Azure

-Azure<-> Azure in different/same data center

-Script from onpremise to SQL Azure need to convert

Diagnostic(using System.Diagnostic)

-Performance

-ResourceUsage

-Troubleshootingand debugging

-Problemdetection

-Quality ofService Metrics

-CapacityPlanning

-Trafficanalysis

-Billing

-Auditing

How diagnostic work

-Role Instance start

-Diagnostic Monitor start

-Monitor configured

-Monitor buffer data locally

-User interface to storage

-schedular

-ondemand

How to implement

-Deploy Diagnostic Manager class

-Role Instance Diagnostic Manger class

-Diagnostic Monitor class

Reconfig

-Remoteconfiguration

Security (protect any attack)

-Layer of security

-Human security

-Application security

-Exception

-Auditand logging

-Authenticationand authorization

-Identity- who you are, collection of attribute of entity

-Rolebase

-Membership

-Identityonly has name, if need more information, need to go to identity provider likeActive Directory

-Claimbase

-Token,colletion of claims, the full set of information is a token, authorization is base on if a claim allowyou to do then you can do this

-SecurityToken Service issue token, I trust service. service trust me, it is the real one. I will take this token, trust these information and use it

-Identity provider tell security token service what to put into token

-Windows Identity Framework

-Build new or reference existing STS

-Easy to implement claim base Identity

-just need to Add STS reference

-Network security (microsoft better)

-OS\DB security(microsoft better)

-physical security(microsoft better

-Windows azure AppFabric: Access Control Service

-similar infrustructure : OpenID

-Shared Access Sinature

-Table& Queue need to access via storage account

-Blobcan be access from Web Browser

-SAS

Scalability, Caching & Elasticity

-Scalability

-Do more work at the same amount of time, more thoughtput

-Vertical Scale Up - simple to implement

-biggerbox, more cpu, more resource

-Horizonal Scale Out

-more boxes

-Scalability!=Performance

e.g:Session in process vs. in sql server

-How to improve?

-lessshare resource

-lesstransaction

-lesssession

-Caching

-Improve performance and scalablility

-Scenarios

-RSSFeed

-Readoften data

-Type

-ClinetCaching - ETags

-beneifts

-preventsclient downloading un-necesary data

-problems

-stillreuqire to round trip to server

-CDN,Blob Storage

-Elastic

-Add/RemoveCapacity

-viaconfig

-viaAPI

-Monitormetric

-Primary metric(actual work done)

-request per sec

-queue messages process/ interval

-Secondary metric

-CPUutilization

-Queue Length

-Response time

-Derivative metrics

-reateof change of queue length
