Ceph OSD hardware - a pragmatic guide
Designing Ceph clusters is hard. Throw OpenStack into the mix, and it gets even harder. There are many different ways in which a Ceph clusters can be configured. Same for selecting right hardware. This session will give a solid start into world of Ceph-based storage (in the context of OpenStack).

Designing Ceph clusters is hard. Throw OpenStack into the mix, and it gets even harder. There are many different ways in which a Ceph clusters can be configured. Same goes for selecting the right hardware. This session will give you a solid start into the world of Ceph-based storage (in the context of OpenStack).

You will learn all the lessons learned by us the hard way when operating our two Ceph clusters over the past several years including all necessary recommendations on picking the right hardware for Ceph, as well as some tips on optimising the deployed Ceph cluster for OpenStack.

During the session will concentrate on what to consider when creating your very own Ceph cluster, what are the common problems with Ceph to be aware of, what is benchmarking and profiling Ceph, what to know about fat node vs thin node, what’s the best SSD for journal (Spoiler alert: one does not exist, here’s why) and, the last but not least, what is the sweet spot between storage density, price, and performance.

The session will be a good blend of high level information combined with various useful to know technical details which we’ve learned the hard way, so that you don’t have to.

From zero to hero: how to get your private cloud project to take off
In this talk you ‘ll learn how to get your Openstack private cloud project going from zero to a solid private cloud implementation. We’ll cover everything from hardware specs to deployment methods, operations and lessons learned.

Introduction

As any IT project clear goals are important, so we’ll start by discussing the biggest pitfalls of Private cloud projects.

Hardware specs

You private cloud will need some hardware to run on, I’ll present you a standard Openstack hardware configuration/bill of material for different capacity targets: what to buy, how many and how much it costs: servers + storage + network.

Deployment methods

The next step is to setup Openstack on your new hardware, here we’ll discuss and compare different options: vendor distributions, Kola (Openstack on Containers), Fuel, Openstack Ansible, …

Operations

Now that your Openstack deployment is up and running, let’s cover monitoring and capacity management for Openstack: What to monitor? How to update your capacity management processes for Infrastructure as a Service?

Behind the Curtains: Predictable Performance with Nova
A great introduction to Nova and Neutron to help users understand how different configuration changes impact the VM performance. The session will help to better understand how to deploy a virtual machine for predictable performance and how to troubleshoot problems when things go wrong.

A behind the scenes look at booting a virtual machine. Examine what happens when a VM is launched and booted from Cinder volumes with Neutron ports and PCI-passthrough/SRIOV. A great introduction to Nova and Neutron to help users understand what is happening and how different configuration changes impact the VM performance. Kernel tweaks, Numa placement, optimizations available but not well known. People working with OpenStack in Telecom or the Internet of Things in production or developing on top of OpenStack would benefit from this talk to better understand how all the pieces come together to successfully deploy a virtual machine for predictable performance and how to troubleshoot problems when things go wrong.

Where next for OpenStack and Containers?
Container technologies are now available on every major public and private cloud platform. So why are OpenStack users adopting containers 3x faster than the rest of the enterprise market?

The market for container software solutions will soon approach $3bn and is growing at 40% a year, largely driven by the promise of portability, micro-services based cloud-native apps and a growing focus on DevOps. Container technologies are now available on every major public and private cloud platform. So why are OpenStack users adopting containers 3x faster than the rest of the enterprise market?

In this session, we’ll explore why containers are such a hot topic and why OpenStack is the ideal platform for developing, orchestrating and running containers for CI/CD and DevOps.

A practical approach to ensuring GDPR compliance in your OpenStack cloud
If you missed GDPR you may get hurt. It's a law with hefty fines in combination with class action law suits. Luckily there is a rational and holistic approach you can take when it comes to fixing your OpenStack cloud to ensure compliance with GDPR.

Advanced Network Services in OpenStack: Real world stories
This session and stories are about elastic, multi-tenant, L4-L7 network services in OpenStack. Real world Enterprise production Load Balancing as a Service. Ddos mitigation and web application firewalls. We will demo load balancing ,real-time application monitoring services in Horizon and Heat.

This talk is about removing hurdles for deploying OpenStack in 24/7 large scale enterprise environments.

Our customers run OpenStack at very large scale and sharing their and our experiences is of course part of the story. Real life stories and examples about integration with SDN’s. Why analytics, HA and real-time monitoring is crucial for their 24/7 Network Operations centers. And if we talk the talk, we walk the walk, so we end with a demonstration of load balancing, ddos mitigation, SSL analysis and more in OpenStack.

Image Build as a Service: Why It Makes Sense to Build Your Own Cloud Images

What if the community or vendor provided cloud images do not fit your requirements?

Like when your cloud needs to offer

Ø  high performance drivers

Ø  additional security hardening

Ø  support for different hypervisors

Ø  images with latest available patches

Ø  cloud-specific pre-configuration (e.g. repositories)


For our public cloud "Open Telekom Cloud" (OTC) we decided to build our own images. Utilizing open-source tools like OpenBuildService, kiwi, DiskImageBuilder, OpenStack tools, and build public images, optimized to run on OTC. 

This includes fully automated build, testing and publishing of the images. Following this approach we are able to adapt changes fast, including security patches, hardening and customization.

The image configurations are signed and published along with the resulting images. 

This session presents how we build images and how you could build upon this work to set up your own factory, maybe extending it to build container images as well?
