cloud engines

1. Hypervisor and Container

Docker. Io – an open-source engine for building, packing and running any application as a lightweight container, built upon the LXC container mechanism included in the Linux kernel. It was written by dotCloud and released in 2013.

KVM – a lightweight hypervisor that was accepted into the Linux kernel in February 2007. It was originally developed by Qumranet, a startup that was acquired by Red Hat in 2008.

Xen Project – a cross-platform software hypervisor that runs on platforms such as BSD, Linux and Solaris. Xen was originally written at the University of Cambridge by a team led by Ian Pratt and is now a Linux Foundation Collaborative Project.

CoreOS – a new Linux distribution that uses containers to help manage massive server deployments. Its beta version was released in May 2014.

2. Infrastructure as a Service

Apache CloudStack – an open source IaaS platform with Amazon Web Services (AWS) compatibility. CloudStack was originally created by (formerly known as VMOps), a startup that was purchased by Citrix in 2011. In April of 2012, CloudStack was donated by Citrix to the Apache Software Foundation.

Eucalyptus - an open-source IaaS platform for building AWS-compatible private and hybrid clouds. It began as a research project at UC Santa Barbara and was commercialized in January 2009 under the name Eucalyptus Systems.

OpenNebula – an open-source IaaS platform for building and managing virtualized enterprise data centers and private clouds. It began as a research project in 2005 authored by Ignacio M. Llorente and Rubén S. Montero. Publicly released in 2008, development today is via the open source model.

OpenStack – an open source IaaS platform, covering compute, storage and networking. In July of 2010, NASA and Rackspace joined forces to create the OpenStack project, with a goal of allowing any organization to build a public or private cloud using using the same technology as top cloud providers.

3. Platform as a Service

CloudFoundry – an open Platform-as-a-Service, providing a choice of clouds, developer frameworks and application services. VMware announced Cloud Foundry in April 2011 and built a partner ecosystem.

OpenShift - Red Hat’s Platform-as-a-Service offering. OpenShift is a cloud application platform where application developers and teams can build, test, deploy, and run their applications in a cloud environment. The OpenShift technology came from Red Hat’s 2010 acquisition of start-up Makara (founded in May 2008). OpenShift was announced in May 2011 and open-sourced in April 2012.

4. Provisioning and Management Tool

Ansible – an automation engine for deploying systems and applications.

Apache Mesos – a cluster manager that provides efficient resource isolation and sharing across distributed applications, or frameworks. It was created at the University of California at Berkeley’s AMPLab and became an Apache Foundation top level project in 2013.

Chef – a configuration-management tool, controlled using an extension of Ruby. Released by Opscode in January 2009.

Juju - a service orchestration management tool released by Canonical as Ensemble in 2011 and then renamed later that year.

Ovirt - provides a feature-rich management system for virtualized servers with advanced capabilities for hosts and guests. Red Hat first announced oVirt as part of its emerging-technology initiative in 2008, then re-launched the project in late 2011 as part of the Open Virtualization Alliance.

Puppet – IT automation software that helps system administrators manage infrastructure throughout its lifecycle. Founded by Luke Kanies in 2005.

Salt – a configuration management tool focused on speed and incorporating orchestration features. Salt was written by Thomas S Hatch and first released in 2011.

Vagrant – an open source tool for building and managing development environments, often within virtual machines. Written in 2010 by Mitchell Hashimoto and John Bender.

5. Storage

Camlistore – a set of open source formats, protocols, and software for modeling, storing, searching, sharing and synchronizing data. First released by Google developers in 2013.

Ceph – a distributed object store and file system. It was originally created by Sage Weil for a doctoral dissertation. After Weil’s graduation in 2007, he continued working on it full-time at DreamHost as the development team grew. In 2012, Weil and others formed Inktank to deliver professional services and support. It was acquired by Red Hat in 2014.

Gluster - a scale-out, distributed file system. It is developed by the Gluster community, a global community of users, developers and other contributors. GlusterFS was originally developed by Gluster Inc., then acquired by Red Hat in October 2011.

Swift – is a highly available, distributed object store system, ideal for unstructured data. Developed as part of the OpenStack project.



clustered apache with Conga

this setup architect is

1 Dedcated Server provide ISCSI storage using tgt serices

3 Kvm VM will be node1 node2 node3 for using as cluster nodes

1 kvm install admin panel ” Luci ”

hosts :

OS : CentOS 6.5 64bit

Set Repo for all servers

On All 4 Servers :

yum localinstall

let’s start with dedicated server to to perpar ISCSI storage :

On Host Server :
 pvcreate /dev/sda3 # Create Phyical Volume
 vgcreate iscsi /dev/sda3 # Create Voulme Group
 lvcreate -L 10G -n shared iscsi # Create Logical Volume
 yum -y install scsi-target-utils # install ISCSI services
# set ISCSI share
 vim /etc/tgt/targets.conf
 backing-store /dev/iscsi/shared
 incominguser admin admin
/etc/init.d/tgtd restart ; chkconfig tgtd on# start services

now we finish and start to install iscsi client on all nodes so we can discover storage.

# to be done on node1 , node2 , node3 only :
yum install iscsi-ini* -y # install iscsi packages
 iscsiadm -m discovery -t st -p # discover share
 iscsiadm -m node --target -l # login to ISCSI
 chkconfig iscsid on ; chkconfig iscsi on # auto start set
 fdisk -l # check new drive u can alose see /var/log/messages

now we have storage on all services under /dev/sda

the shared storage Disk is /dev/sda

now will start to install Ricci # cluster client on all nodes 1,2,3 and “luci” admin panel on

# this commands to be run on all nodes 1 , 2 , 3

yum install ricci ccs -y # install Ricci
 /etc/init.d/ricci restart; chkconfig ricci on # set auto start
 echo 1231234 | passwd --stdin ricci # change Ricci passwd

# now we will install “luci” admin panel on luci node only

yum install -y luci # install luci packages
 /etc/init.d/luci start ; chkconfig luci on # set auto start

congratulations now everything is installed let’s go into web panel to create cluseter

login :
username : root
password : root_passwd

Manage cluster >> Create :

Cluster Name : set your cluster name

Add 3 Nodes with same passwd : 1231234

Check all Those options :
Download Packages # the easy way to make cluster config it will download and install all cluster services
Reboot Nodes Before Joining Cluster # to confrim that eveything is ok
Enable Shared Storage Support # because we using SharedStorage /dev/sda

######### Create Cluster #########

it will show you #

Creating node "" for cluster "cluster01": installing packages
 Creating node "" for cluster "cluster01": installing packages
 Creating node "" for cluster "cluster01": installing packages

just wait…..after 1 or 2 mints all nodes 1,2,3 shoud reboot : The system is going down for reboot NOW!

then Luci will show :

Unable to retrieve the status for batch id 678872664 on The node may be temporarily unreachable
 Unable to retrieve the status for batch id 938297290 on The node may be temporarily unreachable
 Unable to retrieve the status for batch id 1889887158 on The node may be temporarily unreachable

don’t worry just more wait……….

now it show show you that eveything is Ok and Cluster is running…..

to be continued

Howto install openstack Centos



In this topic i’ll do install openstack in 2 ways

1- with packstak .it’s tool install and configure all openstack services

2- step by step this will install each openstack services from keystone to dashbored with manual configure


let’s start

Centos 6.5
OpenStack grizzly

frist we need to create repo in our system to get the packages .

create .repo file in /etc/yum.repo.d/

name=OpenStack Grizzly Repository for EPEL 6

then we need to verfiy the new packages

yum repolist
 yum makecache

then now install packstack tool

yum install openstack-packstack

create ssh key for your host .. we will it later


genrate answer file that for auto install all openstack services

packstack --gen-answer-file answers.txt
vim answers.txt

edit what you want nothing is required

now start install

packstack --answer-file = answers.txt

enter you root password…

wait for install to finish.
