Scalextreme – ISV building Cloud based Monitoring & ManagementInside Provisioning Virtual MachinesApplication Patterns:- SLA, Building for availability, IaaS + PaaSSummary Q & A
Getting Started with Virtual Machines1. Create new VMs from Platform supplied “stock images” from VM Image
Gallery
2. Customize a platform stock image and “capture” for future usage
3. Bring your own VMs from on-premises

Scalextreme
ScaleXtreme OverviewCloud-based Systems Management
“Instant On”Manage existing servers or create brand-new servers – no need to use our images, you can use your ownMonitoring, Patch Management, general-purpose Job Automation, Budgets & Cost Control, etc.
Complements Azure management functionality with actual server launch and management capabilities – Windows and Linux fully supported, today
Directly integrates with Windows Azure through management API’s
Worked closely with Microsoft to ensure native integration
Super Easy
1. Create free account at http://www.scalextreme.com/free
2. Link your Azure account to ScaleXtreme
3. Put agent on existing servers or start launching new ones
4. All functionality (patch, job automation) instantly available!
Demo!
Application Patterns
SLA & Building for High Availability
Highly Available Application Pattern
SQL Mirroring for Availability
SharePoint
Designing VMs with Domain Controller
Connecting Cloud Services & VMs over VIP
Connecting Cloud Services & VMs over VNet
Mixed Mode (PaaS + IaaS working together)
4.38 hours of downtime per year
Service Level Agreements
99.95% for Virtual Machines (in Availability Set)
8.75 hours of downtime per year
99.9% for single Virtual Machine
Compute Hardware failure (disk, cpu, memory)Datacenter failures - Network failure, power failureHardware upgrades, Software maintenance – Host OS Updates
What is included

Tips :-1. Add both VMs to
the same availability Set at every layer
2. Configure a load balanced endpoint on Port 80 for UI layer
