In Part 1 of this series Federico Iezzi, EMEA Cloud Architect with Red Hat covered the architecture and planning requirements to begin the journey into achieving zero packet loss in Red Hat OpenStack Platform 10 for NFV deployments. In Part 2 he went into the details around the specific tuning and parameters required. Now, in Part 3, Federico concludes the series with an example of how all this planning and tuning comes together!

Ready for more Fast Packets?!
In Part 1 we reviewed the fundamentals of achieving zero packet loss, covering the concepts behind the process. In his next instalment Federico Iezzi, EMEA Cloud Architect with Red Hat continues his series diving deep into the details behind the tuning.
Buckle in and join the fast lane of packet processing!

For Telcos considering OpenStack, one of the major areas of focus can be around network performance. While the performance discussion may often begin with talk of throughput numbers expressed in Million-packets-per-second (Mpps) values across Gigabit-per-second (Gbps) hardware, it really is only the tip of the performance iceberg. The most common requirement is to have absolutely stable and deterministic network performance (Mpps and latency) over the absolutely fastest possible throughput. With that in mind, many applications in the Telco space require low latency that can only tolerate zero packet loss.
In this “Operationalizing OpenStack” blogpost Federico Iezzi, EMEA Cloud Architect with Red Hat, discusses some of the real-world deep tuning and process required to make zero packet loss a reality!

In the previous two blogposts (Part 1 and Part 2) we demonstrated how to create a dynamic Ansible inventory file for a running OpenStack cloud. We then used that inventory to run Ansible-based validations with the ansible-playbook command from the CLI.
In the final part of our series, we demonstrate how to run those same validations using two new methods: the OpenStack scheduling service, Mistral, and the Red Hat OpenStack director UI.

In Part 1 we demonstrated how to set up a Red Hat OpenStack Ansible environment by creating a dynamic Ansible inventory file (check it out if you’ve not read it yet!).
Next, in Part 2 we demonstrate how to use that dynamic inventory with included, pre-written Ansible validation playbooks from the command line.

Ansible is helping to change the way admins look after their infrastructure. It is flexible, simple to use, and powerful. Ansible uses a modular structure to deploy controlled pieces of code against infrastructure, utilizing thousands of available modules, providing everything from server management to network switch configuration.
With recent releases of Red Hat OpenStack Platform access to Ansible is included directly within the Red Hat OpenStack Platform subscription and installed by default with Red Hat OpenStack Platform director.
In this three-part series you’ll learn ways to use Ansible to perform powerful pre and post deployment validations against your Red Hat OpenStack environment, utilizing the special validation scripts that ship with recent Red Hat OpenStack Platform releases.
