While the instances are getting deleted during Scale In, you need to deregister the license from the ASAv instance.Ĭloud functions are triggered through a Cloud Pub/Sub Topic. Serverless License Deregistering using Cloud Functions You also have a Log Sink with aįilter that is exclusive to the addition of instances while Scale Out. When a new ASAv instance comes up in the instance group during Scale Out, you need to set the SSH Password, enable Password,Īnd change the Hostname because you cannot always monitor the Scale Out process.Ĭloud functions are triggered through a Cloud Pub/Sub Topic during the Scale Out process. Instance comes up in the Instance Group Manager. You use serverless Google Cloud functions for setting the SSH Password, enable Password, and Changing the Hostname when the The utilization level for each metric is interpretedĭifferently based on the autoscaling policy. If you scale based on CPU utilization, you can set your target utilization level at 75% and the autoscaler will maintain theĬPU utilization of the specified group of instances at or close to 75%. The target utilization level is the level at which you want to maintain your virtual machine (VM) instances. To your desired target utilization, and uses this information to determine whether the group needs to remove instances (Scale
The autoscaler continuously collects usage information based on the selected utilization metric, compares actual utilization Only average CPU utilization metrics are used in making The following diagram alongside shows the target utilization metrics. See for more information.Ī Managed Instance Group (MIG) creates each of its managed instances based on the instance template and optional statefulĬonfiguration that you specify. The process of creating those resources can be repeated over and over To parameterize the configuration and allow the reuse of common deployment paradigms.Ĭreate configuration files that define the resources. You can also use Python or Jinja2 templates Google Cloud Deployment Manager allows you to specifyĪll the resources needed for your application in a declarative format using YAML.

Treat your configuration as code and perform repeatable deployments. The following components make up the ASAv Auto Scale for GCP solution. 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.
Cisco asav home firewall download#
Deployment scripts and templates for your ASA version are available at the specified download location. Provided by GCP (Cloud Functions, Load Balancers, Pub/Sub, Instance Groups, etc.).įrom the download location specified by your beta manager, download the files required to launch the ASAv Auto Scale for GCP solution. The ASAv Auto Scale for GCP solution is a GCP Deployment Manager template-based deployment that makes use of the serverless infrastructure 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 GCP 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 instance group the firewall thenĪ 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 instance group the firewall then forwards traffic The ASAv Auto Scale for GCP is an automated horizontal scaling solution that positions an ASAv instance group sandwiched betweenĪ GCP Internal load balancer (ILB) and a GCP External load balancer (ELB). Support for Load Balancers and multi-availability zones.Ĭisco provides an Auto Scale for GCP deployment package to facilitate the deployment. Support for ASAv deployment and multi-availability zones.Ĭompletely automated configuration automatically applied to scaled-out ASAv instances.
Support for scaling metrics based on CPU. GCP Deployment Manager template-based deployment. Some of the key features of the ASAv Auto Scale for GCP implementation include: The following sections describe how the components of the Auto Scale solution work for the ASAv on GCP.ĪSAv Auto Scale for GCP is a complete serverless implementation that makes use of serverless infrastructure provided by GCP (Cloudįunctions, Load Balancers, Pub/Sub, Instance Groups, etc.).
