There are some issues for OpenStack multi-region mode, for example, lack of global view quotas control, resource utilization, metering data, replication of image / keypair / security group / volume , L2/L3 networking across OpenStack, ... etc. OpenStack cascading is the best-matched solution to solve these issues in multi-site multi-region cloud

Deep dive in container service discoveryDocker, Inc.
Service discovery and traffic load-balancing in the container ecosystem relies on different technologies, such as IPVS and iptables, and container orchestrators use different approaches. This talk will present in details how Docker Swarm and Kubernetes achieve this. The talk will continue with a demo showing how applications that are not managed by Kubernetes can take advantage of its native load-balancing. Finally, it will compare these approaches to service-mesh solutions.

Deeper Dive in Docker Overlay NetworksDocker, Inc.
The Docker network overlay driver relies on several technologies: network namespaces, VXLAN, Netlink and a distributed key-value store. This talk will present each of these mechanisms one by one along with their userland tools and show hands-on how they interact together when setting up an overlay to connect containers. The talk will continue with a demo showing how to build your own simple overlay using these technologies. Finally, it will show how we can dynamically distribute IP and MAC information to every hosts in the overlay.

OpenStack and Kubernetes - A match made for Telco HeavenTrinath Somanchi
With the advent of Containerization of Telco Clouds for NFV and SDN based deployments, OpenStack with Kubernetes is a best chosen option to solve the challenges is a better way to build a containerized Telco cloud. This involves, "Kubernetes in OpenStack", "OpenStack in Kubernetes" and "Independent OpenStack and Kubernetes". With this complementing collaboration, in the Stadium of OpenStack's Open Infrastructure, Telecom gaints are developing cloud-native solutions to best fit the next generation networking deployments. In this Presentation, we talk about Containerization and benefits, OpenStack and Kubernetes match making and we give a brief overview on Airship and Kata Container projects.
This presentation features a walk through the Linux kernel networking stack covering the essentials and recent developments a developer needs to know. Our starting point is the network card driver as it feeds a packet into the stack. We will follow the packet as it traverses through various subsystems such as packet filtering, routing, protocol stacks, and the socket layer. We will pause here and there to look into concepts such as segmentation offloading, TCP small queues, and low latency polling. We will cover APIs exposed by the kernel that go beyond use of write()/read() on sockets and will look into how they are implemented on the kernel side.
10 Excellent Ways to Secure Spring Boot Applications - Okta Webinar 2020Matt Raible
Spring Boot is an efficient way to build Java applications with the Spring Framework. If you’re developing apps that handle sensitive data, you should make sure they’re secure.
This session will cover HTTPS, dependency checking, CSRF, using a CSP to prevent XSS, OIDC, password hashing, and much more!
You’ll learn how to add these features to a real application, using the Java language you know and love.

Object Oriented Code RE with HexraysCodeXplorerAlex Matrosov
In recent time we see a large spike of complex threats with elaborate object-oriented architecture among which the most notorious examples are: Stuxnet, Flamer, Duqu.
The approaches to analysis of such malware are rather distinct compared to the malware developed using procedural programming languages.
This presentation will take an in-depth look at challenges related to reversing object-oriented code with respect to modern malware and demonstrate approaches and tools employed for reversing object-oriented code.

Developing Distributed High-performance Computing Capabilities of an Open Sci...Globus
COVID-19 had an unprecedented impact on scientific collaboration. The pandemic and its broad response from the scientific community has forged new relationships among public health practitioners, mathematical modelers, and scientific computing specialists, while revealing critical gaps in exploiting advanced computing systems to support urgent decision making. Informed by our team’s work in applying high-performance computing in support of public health decision makers during the COVID-19 pandemic, we present how Globus technologies are enabling the development of an open science platform for robust epidemic analysis, with the goal of collaborative, secure, distributed, on-demand, and fast time-to-solution analyses to support public health.
Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
