Take container cluster management to the next level; learn how to administer and configure Kubernetes on CoreOS; and apply suitable management design patterns such as Configmaps, Autoscaling, elastic resource usage, and high availability.  Some of the other features discussed are logging, scheduling, rolling updates, volumes, service types, and multiple cloud provider zones. The atomic unit of modular container service in Kubernetes is a Pod, which is a group of containers with a common filesystem and networking. The Kubernetes Pod abstraction enables design patterns for containerized applications similar to object-oriented design patterns. Containers provide some of the same benefits as software objects such as modularity or packaging, abstraction, and reuse.CoreOS Linux is used in the majority of the chapters and other platforms discussed are CentOS with OpenShift, Debian 8 (jessie) on AWS, and Debian 7 for Google Container Engine.  CoreOS is the main focus becayse Docker is pre-installed on CoreOS out-of-the-box. CoreOS: Supports most cloud providers (including Amazon AWS EC2 and Google Cloud Platform) and virtualization platforms (such as VMWare and VirtualBox)Provides Cloud-Config for declaratively configuring for OS items such as network configuration (flannel), storage (etcd), and user accounts Provides a production-level infrastructure for containerized applications including automation, security, and scalabilityLeads the drive for container industry standards and founded appc Provides the most advanced container registry, Quay  Docker was made available as open source in March 2013 and has become the most commonly used containerization platform. Kubernetes was open-sourced in June 2014 and has become the most widely used container cluster manager.  The first stable version of CoreOS Linux was made available in July 2014 and since has become one of the most commonly used operating system for containers.  What You'll LearnUse Kubernetes with DockerCreate a Kubernetes cluster on CoreOS on AWSApply cluster management design patternsUse multiple cloud provider zonesWork with Kubernetes and tools like AnsibleDiscover the Kubernetes-based PaaS platform OpenShiftCreate a high availability websiteBuild a high availability Kubernetes master clusterUse volumes, configmaps, services, autoscaling, and rolling updatesManage compute resourcesConfigure logging and schedulingWho This Book Is ForLinux admins, CoreOS admins, applicationdevelopers, and container as a service (CAAS) developers.

Ruby 3 on Rails is an open source web framework that was released in 2004. Ruby on Rails is being widely adopted because of its simplicity, 4 maintainability and development speed. Computerworld lists Ruby on Rails as the one of the top 5 technologies for 2007. Motivation for this Book Ruby is often compared with PHP, which is the most commonly used scripting language, and with Java, which is the most commonly used programming language. In the trends graph of TIOBE index you might notice that since the middle of 2006 Ruby shows an increase in usage 5 while PHP and Java show a decrease in usage. OReilly Radar has noted the trend towards an increased usage of Ruby on Rails. Statistics aside, Ruby on Rails has some advantages over PHP, which are discussed below. 1. Ruby on Rails is more object-oriented than PHP, thus providing all the inherent advantages of an object-oriented language such as simplicity, modularity, modifiability, extensibility, maintainability and re-usability. 2. Ruby on Rails is web framework whereas PHP is only a scripting language.
