Apache CloudStack's Plugin Model:Balancing the Cathedral with a Bazaar

В докладе рассматривается технология сборки C++ проектов на основе maven, применяемая в Odin Service Automation (OSA)

The document discusses Project Grizzly Comet, an open source framework for building real-time web applications using Comet techniques. It provides an overview of key Grizzly Comet components like CometContext, CometHandler, NotificationHandler, and how they enable asynchronous communication between a server and browsers. Additional related projects like Grizzly Messages Bus, Bayeux protocol, and Grizzlet interface are also summarized.

This document discusses using Maven to manage the build and deployment of Java EE applications. It covers: 1. The components of Java EE applications like EJBs, web services, WARs, and EARs and how to structure them in Maven. 2. How to configure the Maven plugins for each type of artifact like the maven-ejb-plugin, maven-war-plugin, and maven-ear-plugin. 3. Tips for testing the different types of artifacts and deploying the finished application with tools like Cargo.

Kubernetes can manage stateful applications using StatefulSets. StatefulSets ensure each Pod in the StatefulSet gets a persistent unique network identity, stable storage, and ordered deployment and scaling. When a Pod is removed from the StatefulSet through scaling in, its PersistentVolumeClaim and PersistentVolume are retained and not deleted so they can be mounted by new Pods. This allows each Pod's stateful data to persist independently of the Pod's lifetime.

This document provides an overview of vMotion capabilities in VMware vSphere, including: - Types of virtual machine migrations like vMotion, Storage vMotion, and shared-nothing vMotion. - Requirements for vMotion like compatible CPUs and network connectivity. - Enhanced features in vSphere 6 like separate vMotion networking stacks and long distance vMotion. - Best practices for vMotion planning, limitations, and troubleshooting migration errors.

WLST is a scripting tool that can be used to manage Oracle WebLogic Server domains and instances. It has two modes - offline for configuring domains without a running server, and online for managing running servers. The document discusses using WLST offline to create domains from templates, and online to perform tasks like deployment, configuration, and monitoring of running servers through JMX.

This document discusses how to integrate Grails applications with various enterprise systems and processes. It covers integrating Grails with build tools like Ant and Maven, managing dependencies, connecting to legacy databases, deploying applications, and integrating with Spring frameworks for messaging, web services, and other enterprise features. Grails can work with many external systems through plugins, custom ORM mappings, and by treating Grails as a Spring application. This allows Grails applications to fit into a variety of enterprise environments and development processes.

This document provides an overview of System Center Virtual Machine Manager (SCVMM) including its architecture, supported platforms, high availability options, networking capabilities like software defined networks, bare metal deployment, services templates, hybrid cloud integration with App Controller, and managing third party hypervisors. SCVMM provides centralized management of private clouds and hypervisors. It supports features like VM templates, self-service, and role-based access.

This document summarizes a presentation on Spring Boot revisited with KoFu and JaFu. KoFu and JaFu are new flavors of Spring Boot that use functional programming approaches. KoFu uses Kotlin and functional bean registration, while JaFu uses Java and a lambda-based infrastructure. The presentation discusses the benefits of Kotlin and Java evolutions, an overview of Spring Fu which is an incubator for KoFu and JaFu, examples of applications written in each flavor, efficiency gains from using Kotlin and KoFu, the team working on the project, and a roadmap for upcoming features including native application support and automated transformation between configurations.

This document provides troubleshooting information for issues that may occur when using vSphere features and components, including: - Troubleshooting steps for resolving common virtual machine problems like fault tolerant configuration errors and USB device connectivity issues. - Troubleshooting hosts, including vSphere HA states and Auto Deploy problems. - Troubleshooting the vCenter Server and vSphere Web Client, as well as Linked Mode, certificates, and plug-ins. - Troubleshooting availability features like vSphere HA, DRS, and fault tolerance. - Troubleshooting storage, networking, licensing, and other resource management problems.

This was a quick (15 minutes!) tour of Cloud Foundry that I gave at JFokus 2012 introducing Cloud Foundry as the answer to the question, "I've got a working web application and Spring made it easy, but where do I host it?"

This document summarizes a presentation on rearchitecting storage for server virtualization. It discusses how server virtualization impacts storage by increasing random I/O, challenges of shared storage, and various hypervisor storage approaches like shared storage on SAN/NAS, raw device mapping, and their pros and cons. It also covers storage connectivity options, features in vSphere like thin provisioning and storage I/O control, and technologies like NPIV that are important for virtualization.
