Containers will not fix your broken culture (and other hard truths) - ApacheCon 2018

•

2 likes•88 views

The document summarizes the key points from Bridget Kromhout's presentation at ApacheCon. The presentation outlined five "tech truths": 1) Technology is not a panacea, 2) Good team interactions must be built as they cannot be bought, 3) Technology relies on people, 4) Well-defined boundaries between teams are important, and 5) Systems should avoid becoming "Sadness as a Service". The presentation emphasized that technology alone cannot fix organizational problems and that sociotechnical systems require focus on both technical and human factors.

DevOpsDays Chicago 2014 - How Much Is That DevOps In The Window? Chicago, IL 2014-10-07 to 2014-10-08 Two critiques I’ve heard from first-time DevOpsDays attendees are that they felt like they were on the outside looking in and they didn’t take away anything actionable. I posit that these are two aspects of the same problem we’ve created and can solve. What exactly do unicorns, horses, and goats have to do with corporate IT and software development, asks a newcomer? We want to reach outside the echo chamber, so we need to make the jargon and references of this community more accessible. We talk about empathy as the essence of DevOps; we need to ensure we practice inclusion. Whether it’s providing more context for common references or giving clear speaker bios and introductions, we need to ensure our community mindfully welcomes new participants. Being new to the space can mean looking for rubrics and implementable strategies. It’s not wrong to want a list of action items, but acting without reflection isn’t enough. We need to make it clear that the “how” stems directly from the “why” and the “what”. And just because DevOps is for everyone doesn’t mean that DevOps encompasses anything and everything. There’s no RFC for DevOps, but it does go beyond culture to automation, measurement, and sharing. There are many great tools in that space, and large organizations might implement them differently from small ones. Commerce in this space is welcome and expected, but the practice of DevOps itself is not a commodity. Forget hipster DevOps versus enterprise DevOps. The DevOps in the window is just DevOps, and it’s not for sale.

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.

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.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
