Docker is a new way to achieve a super lightweight virtual machine, in the implementation of the principle and application or VM has a huge difference, the professional name is the application container (application Container). (I personally prefer to call it a virtual machine) 1. Installation 1.1 Installing Docker on Ubuntu 14.04 Prerequisite Requirements: Kernel version must be 3.10 or above Follow t

Prerequisites Using Docker recently is a lot more personal than a virtual machine. However, installing Docker under Linux and Windows will overwhelm a group of people that we don't want to see. This article describes in detail the installation of Docker-ce and Nvidia-docker under Ubuntu, and how to use the domestic im

Turn on the CPU virtualization feature (self-Baidu) before installing the VM so this skips. Specific view can open Task Manager, performance->CPU see if there is virtualization: Enabled typeface Download Docker Toolbox http://mirrors.aliyun.com/docker-toolbox/windows/docker-toolbox/ Docker has CE and

The Java EE platform is comprised of a suite of services (service), application interfaces (APIs), and protocols that provide functional support for developing enterprise applications. 13 Core technologies are JDBC, JNDI, EJB, RMI, JSP, SERVLET, XML, JMS, Javaidl/corba, JTS, JTA, JavaMail and JAF.What is enterprise-class application?1. The amount of data is particularly large.2. The user is very much.3. High performance requirements.4. High security r

Docker Introduction Docker is an open source application container engine that allows developers to package their apps and dependencies into a portable container, and then publish it to any popular Linux machine or virtualization. Containers are completely using the sandbox mechanism, and there will be no interface between each other. Profile Docker to give a

Section 1:application Design Concepts and principles Explain the main advantages of a object-oriented approach to system design including the effect of encapsulation, inherit Ance, and use of the interfaces on architectural characteristics. Describe how the principle of "separation of concerns" have been applied to the main system tiers of a Java Platform, Enter Prise Edition application. Tiers include client (both GUI and web), Web (Web Container), Business (EJB container), integra

Profile The biggest change in the Docker 1.12 version is the integration of Docker Swarm, which provides a engine model under Docker swarm, which is mainly about Docker swarm. The Docker engine itself provides only container technology and does not solve container orchestr

Currently, there are 3 versions of the Java 2 platform, which are Java 2 platform Micro (Java 2 Platform Micro edition,j2me) for small devices and smart cards, Java 2 Platform Standard Edition for desktop systems (Java 2 Platform Standard edition,j2se), Java 2 Platform Enterprise Edition for creating server applications and Services (Java 2 Platform Enterprise edition,j2ee). Java EE is an architecture that leverages the java-based 2 platform to simpli

J2ee| Project In my experience as a developer, senior developer, architect, I have encountered good, poor, and even ugly enterprise-class Java projects. When I ask myself what makes a project successful and another failure, I find it hard to get a perfect answer, as if it's hard to define all the software projects with success. The Java EE project is no exception. Therefore, the project is divided into different levels of success or failure. In this a
