Are you the only one working on your Chef configuration? I was. Then within six weeks my client quadrupled the staff working with Chef. Okay, they just hired three people but that was still disruptive. We had to learn how to work together in the same repo. While I knew all the 'best practices' around testing and deploying cookbooks it wasn't as critical when I was the only one committing changes. Suddenly I needed a better plan. Implementing the community practices would only get me so far. I needed to help this team of diverse skill levels manage their work AND their Chef repository. I needed to highlight to my customer when we were processing interrupts at the expense of scheduled work. I needed to make sure the work was small enough that no one disappeared down a rabbit hole for days on end, but still met the needs of the rest of the organization. I needed Kanban. In this talk I will walk through my experiences, painful and glorious, building a team and managing their work. I will cover the good, the bad, and the ugly of a deadline crunched, pre-launch operations team and what we did to bring sanity, from discovering the real flow of work to documenting interruptions, and how we used (and misused) Chef throughout.

SDN, Network Virtualization and the Software Defined Data Center – Brad Hedlund

Chef Software, Inc.

IT organizations around the world are transforming data center operations and economics by virtualizing their networks. Much like server virtualization decoupled VMs from the underlying X86 server hardware transforming the operational model of compute, network virtualization decouples software-based virtual networks from the underlying network hardware to enable a new operational model for networking. Deployed non-disruptively on any existing network without change, network virtualization transforms the physical network into a pool of capacity that can be consumed and repurposed on demand. You will learn how, today, companies like AT&T, NTT, eBay and Rackspace have transformed their operational model and reduced network provisioning time from days/weeks to seconds. You will learn how network virtualization, OpenStack cloud management and Chef automation can be leveraged together and examine the architectural decisions you should be considering now to prepare for this transformation

Using Chef and AppFirst to Automate Scale-out/Scale-down of Web Applications ...

Chef Software, Inc.

We will demonstrate how using Chef and AppFirst you can automate scaling out and down a multi-tiered web application. As Chef builds out the multi-tier stack, it will dynamically add the AppFirst collectors to the servers it’s executing on. Once this is running we will drive load to our web application which triggers an AppFirst alert as utilization thresholds are met. Based upon receiving the alert Chef automatically deploys another web server with an AppFirst collector and adds it to the load balancer. Using AppFirst’s UI we’ll see that our web application is now handling the load without any problems.

The unintended benefits of Chef

Chef Software, Inc.

When most people talk about automating infrastructure, they focus on things like consistency, scalability, and flexibility. While fine goals, we recently converted several projects to Chef for both systems AND application deployment, and found that, with a little work, these tools could also help you enable better software quality assurance, load modeling, and even improve resource allocation. By sharing cookbooks across projects, we were able to standardize practices and eliminate arbitrary differences, while using parameterization to perfectly isolate the special needs of each project. This allowed us to transfer knowledge among staff much more quickly. Pulling in and parameterizing application state – database contents, website assets, uploaded content – allowed us to spin up new environments with as much or as little state as needed. Integrating with Vagrant and Jenkins, we were then able to use chef to treat the entire image – system and application – as a test fixture. As each engineer (ops or dev) has visibility into the whole stack, we can more easily move people between dev and ops, or between projects.

Push jobs: an orchestration building block for private Chef

Chef Software, Inc.

Push jobs is a new feature in Opscode Private Chef that will allow a user to run commands across hundreds of chef managed servers. Push Jobs leverages Erlang/OTP and ZeroMQ to provide scalable and fault tolerant execution. In this talk I’ll cover the general motivation behind the design and an architectural overview of the system. This will include details of we used Erlang and ZeroMQ to build a robust, scalable system. I’ll also do a demo of the push job feature in action, covering the push jobs server, execution client and knife command line interface.

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...

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.
