Open Source Backup Cpnference 2014: Bareos in scientific environments, by Dr....NETWAYS
To backup 110 (partly virtualized) Linux servers the Max Planck Institute for Radio Astronomy has been using Bareos for 5 years now. The full backup volume is constantly growing and has just passed the 35 TiB mark with up to 6 million files per TiB. Naturally there were problems with scalability and flexibility which needed to be addressed.
We are using 2 Spectra Logic T950 (LTO5/LTO6) tape libraries, 40 TiB of disk backup space, and a dedicated 1GbE/10GbE backup LAN.
As it may be an inspiration to other users, we would like to share our experience utilizing virtual full backups, concurrent jobs, backup of Heartbeat/DRBD Failover Clusters and integrating Bareos with REAR for disaster recovery.
Coming from TSM, passing Bacula on the way, we finally found our destination with Bareos!
The Max Planck Institute for Neurological Research operates several brain scanners for human and animal studies. Imaging techniques used here comprise magnetic resonance imaging (MRI), positron emission tomography (PET), optical imaging and microscopy.
Research is often interdisciplinary, including contributions from the fields of biology, physics, medicine, psychology, genetics, biochemistry, radiochemistry – with very heterogeneous characteristics of data and analysis methods. Backup requirements range between file systems with literally millions of very small files (DICOM raw data or FSL intermediate results) to files of 200 GB+ size (PET listmode).
“Good Scientific Practice” mandates backup/archiving primary data and “everything else needed to reproduce published results” (tools, documentation of tool chains, intermediate results) – which is a veritable challenge in a high-end, dynamic lab environment.
Until recently, we have used a HSM system from Sun/Oracle Inc (SAM-FS) to meet our requirements of backup and archiving, in particular, using HSM-type filesystems for scientific computing in order to have a fine-grained backup.
However, a significantly larger and more powerful system was needed and we are now migrating to a Quantum i6000 (LTO-6) tape library with Grau OpenArchiver as HSM frontend. With help from our colleagues in Bonn (MPI for Radio Astronomy), we were able to use Bareos for archiving some vital filesystems (backup-to-disk using a HSM file system with WORM tapes; one job per file; file archives < 5 GB; mostly unixoid backup clients).
We are very pleased with the performance, ease of handling and flexibility this approach offers, e.g. when using incremental backups of virtual machines, listing the 5 largest files can tell a lot about a system’s “health”; pre- and posthooks allow some interesting security features in an ESX-cluster environment (taking network interfaces automatically up before saving sensitive data and shutting the interfaces down afterwards); analysing backup reports reveal longterm trends for hot spots, etc.

Nicola Iarocci - Git stories from the front line - Codemotion Milan 2017Codemotion
In the years spent on the front line managing open source projects and applications developed by distributed teams, I've managed to gather quite a few Git stories from the trenches. In this practically oriented talk, I will share some patterns and practices I have collected while on the front. We will first go through some useful git aliases, then touch on topics such as the various git branching models, long-running branches, conflict management, the rewriting of project history, etcetera. Oh and yes, the (in)famous Git rebase will be covered too.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
