![]() The Logic App is delivered as a JSON file. The Logic App is used to orchestrate and pass information between the auto scale Azure functions.Įach step represents an auto scale Azure function or built-in standard logic. This orchestrator sequences the execution of these functions and exchanges information Azure functions are independent entitiesĪnd cannot communicate with each other. The Auto Scale Logic App is a workflow, i.e. The functions are as discrete as possible to carry out specific tasks, and can be upgraded as needed for enhancements and These functions are delivered in the form of compressed Zip package (see Build the Azure Function App Package). ![]() Monitor the ASAv load and trigger Scale In/Scale Out operations. The basic functionality includes:Ĭommunicate/Probe Azure metrics periodically. The Function App is a set of Azure functions. The following components make up the ASAv auto scale for Azure solution. See Build Azure Functions from Source Code for instructions on how to build the ASM_Function.zip package. Check GitHub regularly for updates and ReadMe instructions. Note that Cisco-provided deployment scripts and templates for auto scale are provided as open source examples, and are notĬovered within the regular Cisco TAC support scope. Deployment scripts and templates for your version are available in the GitHub repository. Infrastructure provided by Azure (Logic App, Azure Functions, Load Balancers, Virtual Machine Scale Set, and so on).ĭownload the files required to launch the ASAv auto scale for Azure solution. The ASAv auto scale for Azure solution is an Azure Resource Manager (ARM) template-based deployment which makes use of the serverless Make sure you follow the steps and order of execution as described herein. Make sure the prerequisites are met before you start deployment. Read the entire document before you begin your deployment. This document covers the detailed procedures to deploy the serverless components for the ASAv auto scale for Azure solution. The number of ASAv instances in the scale set will be scaled and configured automatically based on load conditions. The ILB distributes outbound Internet traffic from an application to ASAv instances in the scale set the firewall then forwards traffic to Internet.Ī network packet will never pass through both (internal & external) load balancers in a single connection. The ELB distributes traffic from the Internet to ASAv instances in the scale set the firewall then forwards traffic to application. The ASAv auto scale for Azure is an automated horizontal scaling solution that positions an ASAv scale set sandwiched between an Azure Internal load balancer (ILB) and an Azure External load balancer (ELB). Support for enabling and disabling the auto scale feature.Ĭisco provides an auto scale for Azure deployment package to facilitate the deployment.
