Auto-Scaling BIG-IP VE Devices in an Azure Cloud
What does a service scaling group do?
When you create a service scaling group (SSG), you specify thresholds that
prompt new BIG-IP VE devices to be created (
scale out
) and thresholds
that prompt BIG-IP VE devices to be deleted (scale in
). This scaling
helps you better manage resources, saving you money because you are paying only
for the resources you're using.After you configure the service scaling group and deploy applications to
it, you and your application managers will have a centralized view into all of the aspects of
your traffic and device details, including analytics and health. This means that you can be
alerted to a problem as soon as it occurs, making it easy for you to troubleshoot and quickly
address issues with your applications.
Create a service scaling group to manage applications in
Azure
When you create a service scaling group, you specify the parameters
that prompt BIG-IP VE devices to be automatically created or deleted. You also define
the alerts that you want to receive when certain events happen.
When BIG-IQ deploys a BIG-IP
device to an SSG, the device is provisioned with a single network interface. Only
devices with a single network interface are supported in an SSG.
- At the top of the screen, clickApplications.
- On the left, click .
- Near the top of the screen, click theCreatebutton.
- Type aNameand an optionalDescriptionto help you identify this service scaling group.The name you specify displays in your Azure environment for each auto-scaled BIG-IP VE device. This helps you group your BIG-IP VE devices for easy identification.
- From theCloud Environmentlist, select your Azure environment.
- In theMinimum Device(s) Requiredfield, type the fewest number of BIG-IP devices you want running at any given time.
- In theMaximum Device(s) Requiredfield, type the largest number of BIG-IP devices you want running at any given time.The maximum is 4 devices.
- In theMaximum Application(s) Allowedfield, type the largest number of applications you want running simultaneously on this service scaling group.
- In theScale-Out Cooldown Periodfield, type the number of minutes you want Azure to create more BIG-IP VE devices, before scaling out again.The scale-out cooldown period is important, because it prevents the creation of additional devices before the previous scale-out has gone into effect.
- For the Scale-Out settings, specify the CPU and throughput parameters you want to prompt Azure to create new BIG-IP VE devices.
- In theScale-Out Cooldown Periodfield, type the number of minutes you want Azure to create more BIG-IP VE devices, before scaling out again.The scale-out cooldown period is important, because it prevents the creation of additional devices before the previous scale-out has gone into effect.
- For the Scale-In settings, specify the CPU and throughput parameters you want to prompt Azure to remove BIG-IP VE devices.
- In theScale-In Cooldown Periodfield, type the number of minutes you want to wait after Azure removes BIG-IP VE devices, before scaling in again.The scale-in cooldown period is important, because it prevents Azure from removing devices before a previous scale-in activity has gone into effect.
- In the Health Status Rules area, select the events and metrics that you want to trigger an alert.
- In the Notifications area, select the events you want to prompt a notification, and the options for how you want to be notified.If you select SNMP traps, be sure you have SNMP configured on BIG-IQ. If you select the option to send email, you must have SMTP configured on BIG-IQ.
