What Does the Cloud Mean for the IT Professional? Joey SnowTechnical EvanglistMicrosoft Corporation

SESSION CODE: WSV310

Steering the Cloud: IT Pros and Windows Azure

• Windows Azure is Microsoft’s cloud services platform.• Allows for hosting of Web Services and Applications on

Microsoft owned data-centers.

What you probably know:

• Is the IT Pro still needed?• Does my job change?• What am I going to do?

What you’re probably wondering:

Platform Continuum

• Bring your own machines, connectivity, software, etc.

• Complete control• Complete responsibility• Static capabilities• Upfront capital costs for

the infrastructure

• Renting machines, connectivity, software

• Less control• Fewer responsibilities• Lower capital costs • More flexible• Pay for fixed capacity,

even if idle

On-PremisesServers

Hosted Servers

• Shared, multi-tenant infrastructure

• Virtualized & dynamic• Scalable & available• Abstracted from the

infrastructure• Higher-level services• Pay as you go

Deployment: Upgrading a Service

Deployment

VIP Swap Rolling Upgrade

Upgrades the entire serviceTurns the staging environment into the production, and production into stagingAny existing state will be lost

Deployment: VIP Swap

VIP Swap

myapp.cloudapp.net <guid>.cloudapp.net

You can upgrade a single role, and not have to upgrade the whole serviceSo your service remains availableYou can have ‘stateful’ things going on in the background

How do I get to my monitoring data?On demandOn a schedule

When transferring data, you may specifyTime range for transferFilter Level (Event Logs, Trace Warning vs. Trace Error)Source (Event log, IIS, Dumps, etc…)’

The transfer is stored byDeployment IDInstance

All of this can be configured either At start time

Good: Automatically configured when you scale up.Bad: If you want to change it you have to redeploy

Remotely using the Windows Azure Diagnostics APIGood: Can change information gathered at any timeGood: You don’t have to dev anythingBad: On a per-instance basis, so when scaling, need to update monitors on the new instances.

Common Diagnostic Tasks

Standard costs apply for transactions, storage & bandwidthData Retention

Local buffers are aged out by the Diagnostic Monitor according to configurable quotasYou control data retention for data in table/blob storage

Query Performance on Tabular DataPartitioned by high-order bits of the tick countQuery by time is efficientFilter by verbosity level at transfer time
