Agenda Understand elasticity Autoscaling Application Block Azure Scalability How to achieve elasticity Autoscaling Application Block Definitions Usage scenarios Handling varying load levels Implementing your AAB application

Understand elasticity Windows Azure is a scalable platform Which allows you to add and remove resources With flexible pricing Flexible

Understand elasticity Scaling is manual, based on your decisions Flexible

Understand elasticity You can automate scaling: Service Management API PowerShell Writing your own code 3rd party tools Or use Autoscaling Application Block

Autoscaling Application Block Part of Enterprise Library Integration Pack for Windows Azure Same configuration and usage with the other EL blocks A block designed for elasticity / autoscaling Azure applications From the Microsoft Patterns and Practices team

Autoscaling Application Block Business reason: Minimize operational costs: Reduce manual work Reduce the risk of introducing mistakes when scaling Pay exactly what you need

Autoscaling Application Block Usage scenarios: Predictable load patterns. E.g.: business hours, days of week, etc. React to specific resource usage variations

Autoscaling Application Block Reactions to usage variations: Instance scaling. Add or remove instances (virtual machines actually running your app) Throttling. Limit or disable application features

Autoscaling Application Block AAB collects monitored data from your Windows Azure application Based on your rules, initiates scaling actions AAB is part of a custom application (that you build), hosted on premises or in Windows Azure

Autoscaling Application Block Resources involved: 1 “monitor” application which you develop, based on AAB Hosted in Azure or on Premises Rules XML file Diagnostics enabled in the Azure application Azure Table Storage which stores logs

How about multiple applications? 1 Monitor application, with multiple Autoscaler instances The same application in 2 datacenters? Same as above

Common mistakes Autoscaling (automatically) while performing an update Lack of limits (min and max instance count) No “opposite” rule. i.e.: scale up for a certain condition -> make sure you scale down for the opposite condition Host the monitoring / autoscaling app on premises No stabilizer
