Development with Containers Moderator: Jeffery Sica Orchestration and Management with Containers Moderator: Bob Killen The Container has revolutionized how many industries and enterprises develop and deploy software and services. While the promise of containers to improve reliability, reproducibility and sharing application is helping to drive this adoption, there are still questions and concerns that are holding back broader adoption. In this BOF we will provide an opportunity for the Michigan IT community to engage with the local leaders in this area that are developing solutions and promoting the container model in their units This BoF has been broken into two high-level topics: Development with Containers that is geared toward developers working with and implementing containerized applications, and Orchestration and Management with Containers that is geared toward sysadmins that are hosting and maintaining production-level containers. There will be an overview followed by an interactive period where the audience can ask questions of our experts and share their experiences with others. A key goal of these sessions is to understand and develop an agenda for solving questions and concerns that are holding back broader adoption.

Michigan IT Symposium 2017 - Container BOF

Jeffrey Sica

A talk given on Tuesday and Wednesday the 27th and 28th of February 2018 at the Docker Mountain View and Docker SF meetup groups. In this talk, Docker Captain Phil Estes provides a history of the Docker engine from its early days as a single statically linked binary providing all the Docker engine functions to today's Moby and Docker CE projects comprising multiple projects and layers, including the Open Container Initiative (OCI) specifications and runC implementation, and the Cloud Native Computing Foundation (CNCF) containerd project. This talk also describes how these lower layer components spun out from Docker are being used to enhance other projects and offerings in the container ecosystem.

Docker Engine Evolution: From Monolith to Discrete Components

Phil Estes

A talk given on December 6, 2017 at KubeCon/CloudNativeCon in Austin, Texas. In this talk, Phil talked briefly about containerd history and design, but the bulk of the talk was a live coding demo of creating a simple client for containerd to learn about the clean and simple API design for the client library and gRPC services. The GitHub project https://github.com/estesp/examplectr has the code and sample LinuxKit assembly used for the code and example client demo.

A talk given at DevOps Pro Vilnius on March 15, 2018 about container security. In this talk we discussed the core topics around the container ecosystem (host, runtime, image) applicable to both Docker and Kubernetes, as well as discussing usable security/secure by default, and defense in depth principles. Also discussed were security futures like Project Grafeas, libentitlement, LinuxKit concepts, and trusted/untrusted container runtimes in Kubernetes.

Apache Beam is a unified batch and streaming programming model. Apache Beam runs on various execution backends, such as Apache Flink, Apache Spark, Apache Samza, Apache Gearpump, Apache Hadoop, and Google Cloud Dataflow. Up until recently, Java was the predominant language for writing Beam Jobs. However, thanks to the Beam portability project you can now write your pipelines in other languages (Java/Scala/Python/Go/SQL). The benefit of this is simple - Not only can you use your favorite programming language to write data processing pipelines but also all of its libraries. After a brief introduction to Apache Beam, we want to explain how cross-language portability was made possible. Further, we want to showcase the portability with TFX, a Python library for machine learning with TensorFlow. This talk is for everyone who wants to learn about Apache Beam, its API, and its portability layer. No machine learning knowledge required.

Intermediate languages are used in compiler construction to simplify retargeting compilers to multiple machine architectures. In the implementation of \emph{domain-specific languages} (DSLs), compilers typically generate high-level source code, rather than low-level machine instructions. DSL compilers target a software platform, i.e. a programming language with a set of libraries, deployable on one or more operating systems. DSLs enable targeting \emph{multiple} software platforms if its abstractions are platform independent. While transformations from DSL to each targeted platform are often conceptually very similar, there is little reuse between transformations due to syntactic and API differences of the target platforms, making supporting multiple platforms expensive. In this paper, we discuss the design and implementation of PIL, a Platform Independent Language, an intermediate language providing a layer of abstraction between DSL and target platform code, abstracting from syntactic and API differences between platforms, thereby removing the need for platform-specific transformations. We discuss the use of PIL in an implemementation of WebDSL, a DSL for building web applications.

In today's digital world, trust is key to customer relationships, but keeping it is a huge challenge. Customers are well-informed and empowered, quick to change brands if their trust is broken, even if it costs them more. This puts a lot of pressure on organizations to handle trust and safety issues with great care and transparency. The challenge, however, is real. Fragmented solutions have left privacy, legal, and security teams in a perpetual cycle of catch-up, struggling to update privacy notices, manage customer data rights, and answer lengthy security questionnaires—all while trying to prove ROI to the business. It's a thankless job, filled with repetition, tedious tasks, and constant interdepartmental coordination. Combine this with fast regulatory changes and the quick evolution of AI, and it becomes overwhelming. Join this webinar to learn more about TrustArc's new innovative solution Trust Center, the only unified, no-code online hub for trust and safety information built for privacy, security, compliance, and legal teams. Trust Center streamlines your path to compliance, shortens the pre-sales cycle, and reduces both legal and regulatory risks, saving time, effort, and cost. This webinar will review: - Why companies are building unified Trust Centers for a robust privacy program. - How unified Trust Centers streamline sales cycles, ensure regulatory compliance, and reduce operational bottlenecks. - How compliance, legal, security, GRC, and privacy teams benefit from a unified Trust Center in terms of needs, pains, and outcomes. - How TrustArc Trust Center saves time and work while reducing legal, reputational, and compliance risk by effectively managing policies, notices, terms, and disclosures, and providing real-time updates on subprocessors.

At its core, the challenge of managing Human Resources data is an integration challenge: estimates range from 2-3 HR systems in use at a typical SMB, up to a few dozen systems implemented amongst enterprise HR departments, and these systems seldom integrate seamlessly between themselves. Providing a multi-tenant, cloud-native solution to integrate these hundreds of HR-related systems, normalize their disparate data models and then render that consolidated information for stakeholder decision making has been a substantial undertaking, but one significantly eased by leveraging Ballerina. In this session, we’ll cover: The overall software architecture for VHR’s Cloud Data Platform Critical decision points leading to adoption of Ballerina for the CDP Ballerina’s role in multiple evolutionary steps to the current architecture Roadmap for the CDP architecture and plans for Ballerina WSO2’s partnership in bringing continual success for the CD

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
