Module 4: Setup a Service scaling group (SSG) in AWS¶
In this module, we will learn about the Service Scaling Group
(SSG) feature
provided with BIG-IQ 6.0 in a the AWS
environment.
The Service Scaling Group
(SSG) gives us the capability to setup a cluster of BIG-IPs
that will scale based on criterias defined by the administrator.
Topology of AWS Service Scaling Group¶
With BIG-IQ 6.0, the Service Scaling Group
is composed of 2 tiers of ADCs.
Depending on the environment, the implementation of the Service Scaling Group
(SSG) will differ.
Environment | Tier1 (called Service Scaler ) |
Tier2 (called SSG ) |
---|---|---|
AWS | ELB | F5 VE |
AWS Tier1/Service Scaler
management - how does this work ?¶
With BIG-IQ 6.0, the provisioning and deployment of Tier1 has to be done upfront by the administrator. It means that:
- The AWS ELB will have to be provisioned
AWS Tier2/SSG
management - how does this work ?¶
With BIG-IQ 6.0, the provisioning of SSG
BIG-IPs is fully automated. You
don’t have to setup anything upfront but licenses for BIG-IQ to assign to the
dynamically provisioned BIG-IPs
To handle the provisioning and onboarding of our F5 virtual edition, we leverage different components:
- our F5 cloud deployment templates
- f5 cloud libs
Note
We will review this in more details in lab4
Application deployment in a SSG
- AWS¶
To ensure the traffic goes through the SSG
as expected, application will be
deployed in a certain manner:
- You will need dedicated
Classic Load Balancer
(AKA ELB previously) per application. The reason is that eachELB
has one public IP/DNS Name (ie you can’t have 2 app runnings on port 443/HTTPS on aELB
) - When the app is deployed from BIG-IQ, we will specify a VS IP that will be 0.0.0.0. This is because ELB can only send traffic to the first nic of an instance and therefore we will deploy 1nic VE in AWS. So traffic and everything will be sent to the nic Self IP.
- This config will be configured on all
SSG
VEs. They will have an identical Setup
In this lab, we will create a Service Scaling Group
in an AWS
environment.
