This document provides an introduction and overview of unikernels. It defines unikernels as specialized machine images constructed from modular operating system libraries that are compiled with an application and configuration code. This results in sealed, fixed-purpose images that can run directly on hardware without an intervening full operating system. The document contrasts the traditional application stack with layers between the application and hardware to the unikernel approach, which aims to remove these layers and provide a single address space for improved performance. It notes challenges in running multiple applications but how virtualization can provide hardware compatibility while unikernels implement drivers for virtual hardware.

Cellular neural
Mukesh Kumar submitted this document about Cellular Neural Networks (CNN). CNN is a revolutionary analog computing paradigm that allows for local communication between neighboring processing units. It has enabled three technological revolutions: personal computers in the 1980s, the internet in the 1990s, and now cheap sensor arrays and artificial sensory organs through CNN technology. CNN is implemented using the CNN Universal Machine, which can perform image processing and Boolean functions. It consists of an array of identical locally connected processing cells that can recognize patterns at high speeds.
Introduction to docker
Docker is a tool that allows users to package applications into containers to run on Linux servers. Containers provide isolation and resource sharing benefits compared to virtual machines. Docker simplifies deployment of containers by adding images, repositories and version control. Popular components include Dockerfiles to build images, Docker Hub for sharing images, and Docker Compose for defining multi-container apps. Docker has gained widespread adoption due to reducing complexity of managing containers across development and operations teams.
Docker introduction
Docker is a platform for developing and running applications within containers. Containers allow applications to be packaged with all their dependencies and run consistently across different computing environments. The Docker platform includes Docker Engine for running containers, Docker images which are templates for containers, and Docker registries for storing images. When running, a container is isolated from other containers and the host machine. Docker uses a client-server architecture with Docker Engine running as a daemon process and CLI client for interacting with it.

The patterns are presented as ways to further improve portability, scalability and operational efficiency of applications running in the cloud.
Docker and Devops
Gene Kim gave a presentation on his 15-year journey studying high performing IT organizations and their use of DevOps practices. He discussed how traditional IT operations created conflict between development and operations teams. However, companies like Google, Amazon and Netflix achieved much higher performance through practices like continuous integration, deployment of smaller changes frequently, automated testing, and monitoring production environments. These practices improved flow, feedback and continuous learning.
Docker intro
Docker allows users to package applications with all their dependencies into standardized units called containers that can run on any Linux server. Containers are more lightweight than virtual machines because they share the host operating system and only require the additional libraries and binaries needed to run the application rather than a full guest operating system. Docker uses containers and an image format to deploy applications in a consistent manner across development, testing, and production. The document provides examples of how to define a Dockerfile to build an image, run containers from images using docker-compose, and common Docker commands.

Unikernels at Polyconf!
Unikernels are specialized virtual machine images built from modular system libraries and configuration added only to the application code needed. This reduces complexity, duplication, and size compared to traditional OSes. The MirageOS unikernel project builds applications into their own specialized OS that is compiled to run directly on clouds or devices. Unikernels allow single-purpose applications to be developed and deployed easily and securely to multiple environments from a single codebase.

Unikernels and Cloud Computing
This document provides an overview of unikernels including definitions, how they work, advantages, approaches and security aspects. A unikernel is defined as a library operating system that compiles an application and required OS libraries into a single standalone executable. It provides the benefits of containers and VMs but with lower overhead through a minimized attack surface and footprint. Different approaches focus on speed, safety or compatibility. Unikernel security is enhanced through strong isolation, a small trusted computing base and limiting what executable code can do.
Docker Online Meetup #31: Unikernels
Unikernels are constructed by combining application code with only the operating system components necessary for that code to run. The result is a highly specialized, single-purpose application which can be deployed directly to the cloud or onto IoT-like devices. Unikernels reduce software complexity by only including code that is required, resulting in portable applications with much smaller footprints and fast boot times.
By combining the familiar tooling and portability of Docker with the efficiency and specialization of next-generation unikernel technology, organizations have a flexible platform to build, ship and run distributed applications without being restricted to a particular infrastructure. Because workloads that reach the data center today are on a spectrum from physical machine to container to hypervisor, only the Docker platform can further widen the scope and provide more flexibility for orchestrating hybrid applications.

Exokernel
The document discusses exokernels, which are a class of operating systems that minimize abstractions imposed on developers. Exokernels allocate basic hardware resources like memory and disk blocks to applications and allow each application to implement its own abstractions through library operating systems. This provides performance and customization benefits over traditional monolithic and microkernel operating systems but requires applications to manage lower-level hardware resources. The MIT exokernel project implemented this approach in systems like Aegis and XOK that allocated processor time, memory, disk storage, and networking to applications.

Kernel (computing)
The kernel is the central component of most computer operating systems. It acts as a bridge between applications and hardware, managing system resources and communication. Kernels can be categorized as monolithic, micro, hybrid, or exokernel based on how operating system services are implemented. A monolithic kernel executes all services together, while a microkernel runs most in user space for modularity. Hybrid kernels combine aspects of monolithic and microkernels.

Ubuntu
The document provides information about the Ubuntu operating system. It discusses Ubuntu's history as a fork of Debian Linux that was created to be more user-friendly. It was founded by Mark Shuttleworth in 2004. The document also covers Ubuntu's design principles, use of the Linux kernel for processes, memory management, file systems, security features, and graphical user interface.
Hybrid kernel
A hybrid kernel is a kernel architecture that combines aspects of microkernel and monolithic kernel architectures. It aims to have the modularity of a microkernel but is implemented similarly to a monolithic kernel, with nearly all operating system services running in kernel space rather than user space. The best known example is the Microsoft Windows NT kernel, which is classified as a hybrid kernel due to some subsystems running in user mode processes rather than purely in kernel mode. Another example is the XNU kernel used in macOS and iOS, which combines the Mach microkernel with BSD components.
Ch22
The document provides an overview of the history and design of the Linux operating system in 3 paragraphs:
Linux was first developed in 1991 by Linus Torvalds as a small kernel for compatibility with UNIX. It has since grown through collaboration over the internet to run on various hardware platforms while remaining free and open source. Early versions only supported 386 processors and basic functionality, while later versions added support for new hardware, file systems, and networking.
The core components of Linux include the kernel, system libraries, and system utilities. The kernel provides core system functions and resource management. Libraries and utilities are developed separately but work together to provide a full UNIX-compatible system. Device drivers, file systems, and network protocols can
Craft april17
This document discusses unikernels and how they aim to optimize application deployment by including only the necessary libraries and system components. It notes that traditional OSes include many more layers than an application may need. Unikernels provide isolation at the virtual hardware level and include only the runtime, dependencies, and drivers required by the application. This results in smaller, more secure deployments that have minimal surface area for attacks and are easier to reason about. The document also describes how unikernels can help address issues like compatibility and efficiency and notes several open source unikernel projects and tools like UniK that allow building and deploying unikernels on different platforms.

Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

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:

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

Unikernels Introduction
- 1. Unikernels Introduction Pradipta K. Banerjee Linux Technology Center, IBM (@pradipta_kr, www.cloudgeekz.com)
- 2. 2 What is Unikernel? From Wikipedia (https://en.wikipedia.org/wiki/Unikernel) Unikernels are specialised, single address space machine images constructed by using library operating systems. A developer selects, from a modular stack, the minimal set of libraries which correspond to the OS constructs required for their application to run. These libraries are then compiled with the application and configuration code to build sealed, fixed-purpose images (unikernels) which run directly on a hypervisor or hardware without an intervening OS such as Linux or Windows.
- 3. 3 Current Application Stack Hardware Kernel (scheduler, memory management, process management, device drivers, network stack, filesystems) For the application to run on the hardware there are many layers User space Kernel space Different Address Spaces runtime application libraries
- 4. 4 Unikernel based Application Stack Hardware Unikernel tries to remove the layers between the application and hardware Ref: http://www.fixup.fi/misc/usenix-login-2015/login_oct15_02_kantee.pdf No privilege transitions between user space and kernel space. runtime application libraries kernel Single Address Space

Example – MirageOS, Rump kernel ● Advantages – Since no privilege transitions required, a library OS provides improved performance by allowing direct access to hardware. ● Disadvantages – Runing multiple applications in a library OS, with resource isolation is complex. – Update and maintenance of the hardware specific device drivers required by the Library OS ● Solution – Leverage OS virtualization (Xen, Qemu/KVM) – Library OS just implements the drivers for stable virtual hardware whereas physical hardware compatibility provided by regular OS hypervisors
