DreamObjects: Using Ceph To Build Open Cloud Services, Ross Turk
In this talk, attendees will be introduced to the Ceph distributed storage platform and learn what makes it unique. The session will also provide insight into the design and operation of DreamObjects, the world's largest deployment of Ceph to date. Last month, US-based hosting provider DreamHost announced the public beta of DreamObjects, a inexpensive, scalable, reliable object storage service for web and application developers. DreamObjects is built upon Ceph, an open source storage platform designed for reliability, performance, and scalability.
DreamHost runs Ceph on everyday Linux servers, transforming three petabytes of commodity disks into an elastic, self-managing object store. Ceph works with applications written for S3 and Swift, allowing users to migrate applications seamlessly to DreamObjects.
In this talk, attendees will be introduced to the Ceph distributed storage platform and learn what makes it unique. The session will also provide insight into the design and operation of DreamObjects, the world's largest deployment of Ceph to date.

“En quoi l'opensource est déterminant dans l'adoption du cloud en entreprise”,
Laurent Letourmy, Ysance
"Dématérialiser son application sous forme de services Clouds sans se lier à une plate-forme ou un fournisseur. Tour d'horizon du PaaS Open Source Cloudify : productivité et contrôle", Gauvain Girault
Le Cloud Computing transforme notre vision sur la façon de fournir des services informatiques à nos utilisateurs.
Les services Cloud sont dématérialisés et faciles d'accès, disponibles à la demande, élastiques, et nous permettent de ne consommer que ce dont nous avons besoin.
Mais quid de l'existant et de sa complexité ? Cela veut-il dire que la richesse applicative dont nous disposons déjà ne peut être fournie à vos utilisateurs en mode Cloud ?
Et avons nous les outils nécessaires pour exposer nos nouveaux services dans le Cloud de manière portable, réversible et à coûts contrôlés ?
Cette session vous éclairera sur les capacités de mise en place de services applicatifs Cloud, à travers l'utilisation de la plate-forme PaaS Cloudify (http://www.cloudifysource.org/), permettant de dématérialiser le socle d'exécution de vos applications, sans changement de code, ni lock in : "Any App, Any Cloud, Your Way".
À cette occasion seront abordés les thèmes suivants :
Les bénéfices du PaaS - Platform as a Service
Automatisation et résilience pour améliorer le temps de mise à disposition des applications et les SLA applicatifs
Portabilité data-center, Cloud privé et Cloud publics
Cloudify et DevOps
Cas d'utilisation : L'intégration de Cloudify au sein d'un portail Appstore afin de délivrer des services applicatifs (Apps) à la demande, en plus de services d'infrastructure (Compute, Storage)
Cas d'utilisation : L'intégration de Cloudify au sein d'une plate-forme de livraison continue (continuous delivery) pour le développement et les tests d'une application d'analyse des réseaux sociaux
"Open Source Software Brings New Freedom to the Cloud",Cyril Reinhard, Acquia
The rise of SaaS, software delivered as a service, is having an enormously disruptive impact on the software industry. Forrester Research estimates that spending on SaaS technology will double by 2013, representing 16% of all software spend. Gartner Research estimates that SaaS software spend is growing at 18%, compounded annually, and will reach $23B by 2015.
At the same time, open source adoption in the enterprise is reaching a tipping point. According to Accenture, 77% of high performance organizations are piloting or committing to open source.
Organizations large and small are looking to SaaS applications to reduce costs and simplify software application management. SaaS provides organizations with a mechanism to reduce their spend on application management, costs that can consume the IT budget. What can open source software do for organizations looking for a cheaper and more flexible SaaS environment?
The presentation will examine:
What is driving the rapid ascent of SaaS?
How can an organization take advantage of both SaaS efficiency and open source innovation – at the same time?
Best practices and case study examples of organisations leveraging the latest developments in open source software
"Sungards aspirations, their technology choices and the problems encountered on the journey", Simon Withers, Sungard & Giles Sirett, Shapeblue
Sungard, is one of the worlds leading software and technology services companies. The objective of this project was to build a global IaaS hosting platform that would allow Sungard’s customers to benefit from the efficiencies of a automated, self service model whilst maintaining the high degree of service associated with Sungard.
The Sungard cloud has been built on Apache CloudStack technology, with Sunagrd recently deciding to become the 2nd biggest contributors to this Apache project.
This case study will talk through Sungards aspirations, their technology choices and the problems encountered on the journey.
"Creating cloud-compatible code right from the start", Fabrice Bernhard, Theodo
My goal : find a way, in a "devops" mindset, to strongly encourage Theodo developers to create cloud-compatible code right from the start for our clients, using open-source solutions
The solution : make the developers responsible for the automatic provisioning and deployment of their testing environment used by the product owner and for which they are responsible (the development method is SCRUM)
The technical details : using LXC, an open-source, highly efficient virtualisation solution for Linux environments, we created a farm of empty systems which are destroyed and recreated in a matter of seconds. This ensures that the developers really automate every detail of the system configuration they need for the effective deployment of their software using as automation tools Python's Fabric and Fabtools. These are the most developer-friendly provisioning solutions we found. The same scripts are then used for cloud provisioning in production, ensuring maximal documentation and easy redeployment
Additional gain : with another process involving backup and data-sharing, the development team is able to develop highly scalable and high-availability applications right from the start, without additional costs
"Lessons Learned - building a large scale cloud with CloudStack", Frits Vlaanderen, LeaseWeb
In this talk, I'll give a tour behind the scenes of a project to build a
CloudStack-based public cloud, that scaled up to thousands of live
customers within half a year. Focus points are lessons learned, designing
a modular platform, and practical pointers that will help you roll your
own. A few examples of challenges we faced:
- Scaling to thousands while keeping performance on par
- Designing your storage system for redundancy and speed
- Tweak
