JBoss EAP for IBM Power Systems
JBoss addingValue to your solution

Take advantage of the superior performance when using Java (1) on Power Systems
• JBoss® Enterprise Application Platform (JBoss EAP) is supported on a variety of market-leading operating
systems, Java™Virtual Machines (JVMs), and database combinations.

• IBM JDK is supported and ready to run on Red Hat Enterprise Linux for Power Systems and recently Red Hat
and IBM tested a series of conﬁgurations using JBoss EAP, RHEL for Power and Power Systems (2)
.

• Red Hat provides both production and development support for supported conﬁgurations and tested
integrations according to your subscription agreement in both physical and virtual environments.

New Stack for POWER Systems

Red Hat Enterprise Linux 7
• RHEL7 Basic Facts

!• What’s changed ?
Public release Jun 2014

Basic Facts
• Based on Fedora 19 and Kernel 3.10

!• Supported Architectures: x86_64, IBM Power
Systems and System z

!• 64bit! 32-bit libraries will be made available

Installer
• The RHEL 7 installation procedure presents a user friendly interface that allows RHEL to be
installed a more comprehensive installation process rather than having 13 linear screens

• Easy to go back to a main page

• Warnings and errors provided to guide the user

System Initialization and service manager
• Uses Systemd, a system and service manager

!• Allows more work to be done concurrently
(possibly in parallel) at system startup resulting
faster system boot times.

!• Integrates chkconfig + service

Filesystems - Many choices

Linux Containers
Application isolation mechanism for light-weight, multi-tenancy environments
with a single underlying OS

Resource_Management_and_Linux_Containers_Guide/sec-Creating_a_Container.html

MS Integration
• Out-of-the-box Linux support of direct interoperability with Active Directory

• Automatic detection of the domain controller to join (AD/IDM)

• Simple, integrated set-up of the authentication configuration

Linux Containers Deep Dive

Linux Containers
Application Containers

(same kernel and /usr as the host system)
Hosting Applications:Application Containers

Linux Containers
• Secure application sandboxing technology

• Promotes ultra multi-tenancy and density

• Carves up the host system and its resources into containers
What are Linux Containers?

Linux Containers
Key elements of Linux Containers

Linux Containers
Linux Containers building blocks
Linux Containers are built using the following RHEL technologies:

!
• Resource Management - Control groups

• Filesystem Separation – Device mapperThin Provisioning

• Isolation - Namespaces

• Security - SELinux

• Tooling – Libvirt-lxc and virt-sandbox-service

!
Deployment model: Plumbed into systemd which allows for launching hundreds of containers

Linux Containers
Red Hat Enterprise Linux - Container Architecture

Linux Containers
Resource Management with Cgroups

Linux Containers
Red Hat Enterprise Linux - Container Architecture
While not technically part of the cgroups work, a related feature of the Linux kernel is namespace isolation, where groups of processes are separated such that they
cannot "see" resources in other groups. For example, a PID namespace provides a separate enumeration of process identiﬁers within each namespace.Also available are
mount, UTS, network and SysV IPC namespaces.

Linux Containers
• Mount : mounting/unmounting filesystems

• UTS : hostname, domainname

!• IPC : SysV message queues, shared memory segments

!• Network: IPv4/IPv6 stacks, routing, firewall

!• PID: Private /proc, multiple pid 1's

!• User: (UID) Just showing up in the Kernel now

!• Mount, UTS, IPC, Network, PID are fully supported in RHEL 7.0
Namespaces

Sample slide
Host based Application Container
Shared RHEL host based application container

!
• Generic application containers

• Run any command / package supported on the host system

!
• Systemd application containers

• Scale – launch 100s of containers using systemd

• /usr in container same as the host OS

Linux Containers

Standalone

Systemd

Linux Containers
Linux Containers Next Generation : Image based Containers and Container Management
Application Containers

(same kernel, different /usr and package set as the host system)

Docker - Image Based Container
Image based Container
• Image based (Docker)

!
• Chroot Application Containers (devops, dev/test)

!
• RHEL/Fedora image with newer packages

!
• Container /usr differs from the host OS

Red Hat, Fedora and Docker
• Red Hat doing heavy lifting in Fedora to ensure Docker runs on a Red Hat based container stack

• Device mapper thin provisioning

• Replaces AUFS dependency in Docker

• Libvirt-lxc sandbox

• Replaces lxc-tools dependency in Docker

• SELinux

Containers versus Virtualization
Containers vs KVMVirtualization
• Startup and shutdown speed

• Ease of Maintenance

• Easy to create

• System-wide changes visible in each container

• For RHEL Shared OS Containers

• Scalability: Number of containers

• Process Memory Sharing
KVMVirtualization vs Containers
• Boot multiple Different Operating Systems

• Including Windows

• Separate kernel

• Better Security

• Kernel crash does not take down host

• Guest Isolation from host changes

• Full Separation

• Features such as live migration and live storage migration
