Welcome to “Let’s Troubleshoot Together” Lab#

The objective behind this section is to collaborate together on a pre-built scenario to put in practice some of the troubleshooting techniques and tools you have learned and benefit from the real power of the Aviatrix platform.

1 - Initial Scenario#

The lab topology can be found below:

1.1. - Notes#

A few notes on the scenario are here:

  • This is an ingress scenario i.e. we have a Wordpress application that we want to publish to the world.

  • The application consists of 3 components Proxy VM, Web Server VM & Database VM.

  • The ALB, the Proxy VM and the Web Server VM reside in us-east-1 region (N. Virginia).

  • The Database VM resides in us-east-2 region (Ohio).

  • The setup exists in AWS but the same logic and methodology can be followed in other CSPs.

  • Public Subnet Filtering Gateway (PSF) is used at the edge of the Ingress VPC to protect any communication from malicious IP addresses.

  • External User will communicate with the Public IP address corresponding to the ALB.

  • ALB will basically terminate the connection and create another connection. Recall that the ALB does SNAT.

  • The target of the ALB is the NLB. Thus the traffic flow will now be from the ALB’s private IP to the NLB’s private IP.

1.2. - Requirements#

  • Time to complete is 90 minutes.

  • One volunteer of the team should share the screen and navigate through the Controller and CoPilot.

  • Access to the VMs is not granted, therefore use solely the CoPilot for resolving all the challenges.

  • The Wordpress application that is very critical to your business is broken! You are going to collaborate together to identify all the issues that are causing it to break.

  • There are 5 challenges that you need to pinpoint and resolve.

  • Once the 90 minutes are done, the instructor will close the breakout rooms and each team will discuss their findings & learnings for ~ 10 minutes.

  • Once this is done, the instructor will highlight some of the key values that the Aviatrix Platform brings into troubleshooting and operating the setup.

1.3. - Wordpress is OK#

Important

If you succeed in fixing all the problems, this how the Wordpress app page would look like.
