MidoNet is an open source network operating system that provides software-defined networking and network virtualization capabilities. It features distributed logical switching, routing, firewalling, load balancing and tunneling using protocols like GRE and VXLAN. MidoNet integrates with OpenStack Neutron and has a REST API for configuration and management. It uses a distributed architecture with agents on each host controlling the Open vSwitch datapath and communicating with a central database for topology and configuration information. The MidoNet community is active on Slack, mailing lists, code reviews and documentation to support the project.

VMware is a leading cloud infrastructure software provider with over $3.77 billion in revenues and over 300,000 customers including all of the Fortune 100 companies. The company's mission is to simplify and automate IT for customers by optimizing efficiency, enabling business agility, and empowering a more productive workforce. VMware is focusing on providing a more flexible, scalable infrastructure for all applications across existing datacenters and public clouds.
This document discusses code signing, which involves digitally signing executables and scripts to confirm the software author and ensure the code has not been altered. Code signing can ensure code integrity, identify the source, and determine if code is trustworthy for a purpose. The architecture involves a code signing tool, kernel module to check signatures, and user-space daemon called by the kernel module. Communication between kernel and user space uses techniques like system calls, ioctl, proc filesystem, and netlink sockets.
The ast package provides data structures for representing syntax trees of Go source files. It defines Node interfaces for nodes in the abstract syntax tree, including Expr for expressions and Stmt for statements. Common node types include Identifiers, BasicLiterals, Function literals, and various expression types. The package also includes utility functions for walking, printing and filtering syntax trees.
OpenStack is an open source cloud computing platform that provides services for managing compute, storage, and networking resources. Quantum is the networking component of OpenStack that provides APIs to virtualize networking and manage virtual networks. It abstracts the network configuration from underlying hardware and supports plugins for different vendors. Quantum provides advanced networking capabilities compared to earlier OpenStack networking through its network, subnet, and port abstractions and plugin architecture.
Cloud Foundry is an open source platform as a service (PaaS) that supports building, deploying, and running applications on the cloud. It supports multiple frameworks like Java, Ruby, Scala, and Node.js and services like SQL, NoSQL, messaging, and analytics. Cloud Foundry uses a distributed architecture with no single point of failure and provides automatic scaling and self-healing capabilities.
OpenStack is an open source cloud computing platform that provides infrastructure as a service. It abstracts compute, storage, and networking resources from physical hardware into a dashboard that manages these resources as virtual machines, object storage, and virtual networks. OpenStack uses a central dashboard and various components like Nova (compute), Glance (images), Swift (object storage), Neutron (networking), and Keystone (identity) that can work with different underlying hardware and be deployed both publicly or privately. Neutron provides network as a service and tools for building advanced virtual networks using plugins that support technologies like Open vSwitch, Linux bridges, NSX, and OpenDaylight.
The document discusses VMware Hybrid Cloud Services. It introduces two VMware executives, Rajdeep Dua and Prasenjit Sarkar, who will present on the topic. The presentation agenda includes an introduction, the role of vCloud Director, VMware's "cloud of clouds" architecture, virtual data centers, VPCs and DCs, network security, tenants, catalogs, and vCloud Connector. It describes the key components and capabilities of VMware Hybrid Cloud Services, including vCloud Director, virtual private clouds, dedicated clouds, tenants, catalogs, and how vCloud Connector can connect on-premises and hybrid clouds.
- Play 2.0 is a web framework for Java and Scala that simplifies development by embracing HTTP rather than fighting it
- It takes a new approach to building web apps in Java by not being built on top of servlet APIs and using an asynchronous programming model
- Developing, testing, and deploying a Play app locally and to CloudFoundry involves creating a project, running it locally, and pushing the compiled code to CloudFoundry which automatically detects and supports Play apps
The document discusses Docker 1.5 and its new features including IPv6 support, read-only containers, Docker stats, and the Docker image specification. IPv6 can be enabled by running Docker with the --ipv6 flag. Read-only containers restrict writes to containers. Docker stats provides live metrics for containers. The Docker image specification defines the format for layered image files and metadata.
This Presentation talks about various aspects of managing the Activity Backstack.
Please note this was prepared last year but most of the concepts are still relevant
The slides give the brief idea of the current situation of the container orchestration integration in OpenStack and how OpenStack Kuryr can improve the situation.
This document provides an overview of Cloud Foundry, including:
1. Cloud Foundry is an open source platform as a service that allows developers to build, test, deploy and scale applications.
2. Cloud Foundry uses a distributed architecture that is self-healing with no single point of failure to allow for horizontal scaling.
3. The Cloud Foundry architecture includes layers like the cloud controller, stager, DEA execution agents, services, router, and uses BOSH for automated virtual infrastructure deployment and management of Cloud Foundry clusters.
The document provides an overview of the Aura framework:
- Aura is Salesforce's framework for building UI components that are reusable, high performing, and support events. It allows for faster development through out-of-box components.
- Components are the building blocks of Aura apps and can encapsulate HTML, CSS, JavaScript and other code. They represent reusable sections of the UI.
- Aura uses an event-driven programming model where components can fire and handle events to respond to user interactions.

REALITYアバターを様々なメタバースで活躍させてみた - GREE VR Studio Laboratory インターン研究成果発表gree_tech
The document outlines the research presentations from an internship program at GREE VR Studio Laboratory. The presentations covered topics like motion capture techniques that could be used in metaverses, generating emotive expressions from sound, and representing metaverses using augmented reality. One presentation proposed a way for users to virtually travel the world together by exploring street view locations and taking photos with their avatars.
The document discusses a quality improvement project at Reality Inc. to reduce app startup time. It began with measuring startup sequences on iOS and Android to identify bottlenecks. This showed networking requests and initializing distributions were slow. Performance was then measured in user environments using Firebase and GCP tools. Startup times of over 6 seconds were found. The project aims to parallelize processes, remove unnecessary tasks, and speed up networking to reduce startup time through ongoing measurement and optimization.
This document introduces two operational support tools for making Cloud Spanner more convenient: Spanner Warming Guy and Spanner Up-Down Guy.
Spanner Warming Guy is a tool that performs warmup of Cloud Spanner before releases. It can add load to Spanner through SELECT queries alone and automatically adjusts the number of SELECT bots.
Spanner Up-Down Guy is a tool that auto-scales the number of nodes in Cloud Spanner. It periodically executes Cloud Functions to adjust the node count according to a pre-defined schedule or the load situation. It can gradually decrease nodes to reduce costs.
