What is the OpenStack Platform? By Peter Dens - Kangaroot
The document discusses OpenStack, an open source cloud computing platform. It provides an overview of OpenStack's history, core projects, and services. The core projects allow users to provision compute, storage, and networking resources. OpenStack uses a modular architecture and is designed to easily scale out workloads across multiple virtual machines. Major contributors include companies like Red Hat, HP, IBM, and Rackspace who aim to develop OpenStack as an open infrastructure for both private and public clouds.

RHEL OpenStack Platform director facilitates planning, deployment, and ongoing operations of RHEL OpenStack infrastructure. It provides a complete end-to-end solution for OpenStack business planning, system deployment, and infrastructure operations through APIs, CLI, and a dashboard. TripleO uses OpenStack components like Nova and Heat to deploy OpenStack to bare metal servers, treating hardware deployment like a special hypervisor. RHEL OpenStack Platform director manages both the production OpenStack cloud and the deployment and management "undercloud".
Red Hat Enteprise Linux Open Stack Platfrom Director
Red Hat Enterprise Linux OpenStack Platform director is a toolset for installing and managing a complete OpenStack environment. It is based primarily on the OpenStack project TripleO, which is an abbreviation for "OpenStack-On-OpenStack". This project takes advantage of OpenStack components to install a fully operational OpenStack environment. This includes new OpenStack components that provision and control bare metal systems to use as OpenStack nodes. This provides a simple method for installing a complete Red Hat Enterprise Linux OpenStack Platform environment that is both lean and robust.
Open cloud infrastructure built for the enterprise
The document discusses Red Hat Enterprise Linux OpenStack Platform. It provides an overview of OpenStack, including what it is, its core projects, architecture and how it addresses IT challenges around flexibility, management, and evolving workloads. It outlines Red Hat's leadership and contributions to OpenStack, including being the largest or top contributor to recent releases. It positions Red Hat Enterprise Linux OpenStack Platform as the enterprise-grade distribution of OpenStack, with benefits like being enterprise hardened, integrated with RHEL, and having long term support.
Red Hat OpenStack Deployment
This document discusses Red Hat OpenStack Platform deployment. It outlines Red Hat's tools for OpenStack deployment including PackStack and Foreman. It also describes common OpenStack deployment patterns such as all-in-one, proof-of-concept with three nodes, active/passive high availability, and scalable high availability. Finally, it lists common host groups for OpenStack deployments including controllers, computes, and storage/network roles.
TripleO
TripleO is an OpenStack project that aims to deploy OpenStack using OpenStack. It provides automation to deploy and test OpenStack clouds at the bare metal layer using tools like Heat, Diskimage-Builder, and Ironic. TripleO designs robust gold images to deploy consistently tested and reliable OpenStack environments, reducing costs of operations and maintenance through continuous integration and deployment techniques. By deploying OpenStack on bare metal with tools like Ironic, TripleO can reliably install and upgrade OpenStack clouds.
Extending TripleO for OpenStack Management
Operational awareness and value for cloud operators has largely been ignored by the OpenStack community. Today with the maturity of TripleO and inclusion of Tuskar, we can now begin to think about TripleO's use as a vehicle for OpenStack infrastructure management.
The question now is How do we extend TripleO with additional value?".
Within this context, there are several areas of integration which can be explored. These include an operator dashboard, infrastructure instrumentation agents, bare metal drivers and other supporting services. Hardware and software vendors can gain insight into what integration looks like from a product point of view.
In this session, we will explore:
- Why TripleO works for infrastructure management
- TripleO management integration points
- What TripleO means for hardware/software vendors
- Early work in this area
Triple o overview
TripleO is an OpenStack project that aims to provision OpenStack cloud services using OpenStack technologies. It uses Heat to orchestrate the installation and configuration of OpenStack on bare metal infrastructure to create an "undercloud". The undercloud then provisions an "overcloud" as an OpenStack tenant using the same OpenStack components and processes. This allows OpenStack to be deployed, managed and upgraded using its native APIs and processes. TripleO leverages technologies like Nova, Heat, diskimage-builder and Puppet/Chef to automate the deployment and lifecycle management of OpenStack clouds.

Speeding up Programs with OpenACC in GCC
In this deck from FOSDEM'19, Thomas Schwinge presents: Speeding up Programs with OpenACC in GCC.
"Proven in production use for decades, GCC (the GNU Compiler Collection) offers C, C++, Fortran, and other compilers for a multitude of target systems. Over the last few years, we -- formerly known as "CodeSourcery", now a group in "Mentor, a Siemens Business" -- added support for the directive-based OpenACC programming model. Requiring only few changes to your existing source code, OpenACC allows for easy parallelization and code offloading to accelerators such as GPUs. We will present a short introduction of GCC and OpenACC, implementation status, examples, and performance results.
OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model."

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
