Cloud Characteristics

On-demand self-service. unilaterally provisioncomputing capabilities, manually or automatically

Broad network access. available over the network ,accessed through standard mechanisms,heterogeneous clients

Resource pooling. serve multiple consumers, multi-tenant model, dynamically assigned, locationindependence

Rapid elasticity. rapidly and elastically provisioned,scale in and out, illusionillusionillusionillusion of infinite resources

Measured Service. metering capability. Pay per use.

What is Windows Azure?

http://www.windowsazure.com/en-us/ Some snippets:

highly available, redundant Load balancing 99.9x% monthly SLA Global datacenters Any language, tools Open REST interfaces Only pay what you use

Easily scale

Service Model Categorization

Microsoft Azure is a public cloud platform-as-a-service (and IaaS)

Platform as a Service (PaaS): consumercreated, deployed to cloud, programminglanguages, frameworks/runtime, tools, no

infrastructure management but application != private cloud (Windows Server 2008 R2,

Hyper-V, System Center)

Application and data is your concern

Compute: virtualized environment (Windows Server2008 R2 / 2012)

Storage: redundant, scalable, available, partitioned

Network : secure connectivity for hybrid apps

Database: relational, for structured data Reporting: Reporting Services

Data Sync: synchronization between SQL Azure / on-

premise SQL server Service Bus: communication channel or queue.

Access Control: claims-based access control

Caching: distributed in-memory cache/session state

Main Components

Virtual Machine Role

To migrate legacy applications to cloud more easily

Enables you to have full control over the OS Image Create portable VHD locally and upload to cloud

storage. No lock-in.

Deploy a solution package Key considerations

You set up, patch, back up

Designed for long or non-automatedinstalls

Durable image

Windows Azure Storage

Scalable storage in the cloud (Geo-)replicated 3 times (immediately consistent) 100TB per storage account Auto-scale (for volume and throughput)

Accessible via RESTful Web Service API Accessible from Azure, on-prem or via internet Best from .NET Client Libraries (DLL) Security: shared secret keys (2 versions), HTTPS endpoint,

shared access signature Various storage types

Local instance disk space, Table, Queue, Blob, Drive, SQLAzure, custom (MongoDB, RavenDB, …)

24.01.2013 Slide 12 of 28

Windows Azure Storage - Blob

Blobs

Large binary storage (audio, video, image, documents, …). Up to 200 GB Stored in container (unlimited containers, CDN deliverable, partitioned

by blob name, meta data). Snapshots. Write leases.

24.01.2013 Slide 13 of 28

Windows Azure Table Storage

Tables (rows of entities)

Entity = set of (up to 255) properties (name/value pairs).Max. 1 MB per entity.

Partitioned by (partition) key. Indexed by row key. Timestamped for optimistic concurrency. Group transactions.

Scales for large number(billions) of entities and TBs.Log, seq. lists, posts

Structured data,no fixed schema,not an RDBMS, OData prot.

Consider the queries24.01.2013 Slide 14 of 28

Windows Azure Queue Storage

Queues (simple message queue)

Non transactional, read at least once, message invisible fortimeout, delete to remove message - otherwise is returned toqueue.

Partitioned by queue name

Any serialized object can bea message. 64kB limit.

Inter-role communication

But: Service Bus Topics/Subscriptionsand Queues (advanced messaging)

Client communication

24.01.2013 Slide 15 of 28

SQL Database

Familiar SQL Server relational database model deliveredas a service Support for existing APIs & tools Built for the cloud with high availability & fault tolerance, 3

replicas Quick and easily provision and manage databases across

multiple datacenters SQL Azure provides logical server Gateway server that understands TDS protocol Looks like SQL Server to TDS Client Actual data stored on multiple backend data nodes

Logical optimizations supported Indexes, Query plans etc..

Physical optimizations not supported File Groups, Partitions etc…

150 GB limit -> sharding

24.01.2013 Slide 16 of 28

Service Bus

24.01.2013 Slide 17 of 28

Relayed communication (NAT/Firewall traversal), WCF relaybindings, Push

Brokered communication(async, pub/sub, reliable),Pull model,

subscription filters (SQL92)

Ports 80, 443, 9350-9353

Events, one-way, rendezvous,direct connection option

Access Control Service (ACS)

24.01.2013 Slide 18 of 28

Security Token Service (STS)

Leverage claims-based (properties of a user in asigned token) identity for web apps

Supported IP like Windows Live ID, Google, Yahoo,and Facebook

Metadata exchange



© Zühlke 2012

Media Services

Create, manage and distribute media

Service platform for upload, storage, encoding, format conversion, content protection, and delivery

HTTP/UDP/REST API for Windows, XBox, iOS, andAndroid, misc. streamingstandards

DRM

Free preview service

Visual Studio Development

Cloud Project Template

For different roles For different languages

Storage Server Explorer

IntelliTrace for historicaldebugging

Package/publish: full,

differential (within seconds) Local development fabric

for debugging and testing(not for ACS, Service Bus, etc.)

Instances going up and down

Networking errors

Intermittent faults

Throttling

Error handling

Retry

Transaction, compensation for consistency

Several instances, fault domains, update domains

Architecture Consideration

Design for failure, Transient Fault

24.01.2013 Slide 25 of 28

Trust, security, legislation, compliance, policies

Commodity hardware (GPU, network topologies, storage, etc.)

Vendor lock-in. No widely seen open cloud standards yet

Latency (request to response; but throughput)

Challenges of distributed architecture (intermittent fault, data architecture,partitioning, Cost-oriented-architecture COA, caching, …)

Integration challenges (e.g. existing on-prem ERP, logistics, etc.)

PaaS development flexibility

Operations, monitoring, backups

Constantly evolving

Azure Considerations

Summary

Microsoft provides one of the richest and mostpowerful cloud services platform.

You experienced development

Cloud architecture is not much different , but thereare some considerations
