OpenStack is an open-source cloud framework for building on-demand
Infrastructure as a Service.
This tutorial in essence distills from this two-page set of instructions for
setting up devstack on a single server primarily for use by developers.
I used a DELL 1950 with 8 GB of RAM, internal hard-drives and two 1000 MB
Download and Set Up Ubuntu
Download Ubuntu 11.10 from here and burn to DVD Boot the server from the DVD
and start the install. I installed the BASE SYSTEM and only one optional
package, the OpenSSH Server. I named my server "ubuntu-server" I configured
eth0 with a static ip address of 10.202.181.21. This will be important as the
HOST_IP address of devstack. Create a user named "stack". Log in as "stack"
See next page for how to Install Devstack...
stack@ubuntu-server:~$sudo passwd to set the root password
Eucalyptus is an open source Infrastructure as a Service cloud offering. What
is unique about Eucalyptus is that it is compatible with Amazon AWS APIs.
This means that you can:
Use Eucalyptus commands to manage Amazon or Eucalyptus instances. Freely move
instances between a Eucalyptus private cloud and the Amazon Public cloud to
create a hybrid cloud.
Eucalyptus leverages operating system virtualization, such as KVM or XEN, to
achieve isolation between applications and stacks. Operating system
virtualization dedicates CPU and RAM to systems and applications such that
they don't ... (more)
BigData (and Hadoop) are buzzword and growth areas of computing; this article
will distill the concepts into easy-to-understand terms.
As the name implies, BigData is literally "big data" or "lots of data" that
needs to be processed. Lets take a simple example: the city council of San
Francisco is required to take a census of its population - literally how many
people live at each address. There are city employees who are employed to
count the residents. The city of Los Angeles has a similar requirement.
Consider are two methods to accomplish this task:
1. Request all the San Fran... (more)
Following my initial introduction to Hadoop and overview of Hadoop
components, I studied the Yahoo Hadoop tutorial, and have a deeper
understanding of Hadoop. I would like to share my learning and help others
Why does Hadoop require HDFS, what's wrong with NFS?
Normal 0 false false false EN-US JA X-NONE
Nothing! NFS been around for years and is incredibly stable. A distributed
file system, such as NFS, provides the functionality required for servers to
share files. It does this by exposing a volume to the network, which users
connect to over the TCP/IP proto... (more)
Cloud computing is a general term for computing services delivered over the
Internet, as opposed to computing services hosted inside your own network; on
your own premises.
These computing services can be as simple as Internet based email or as
complex as a Customer Relationship Management (CRM) application.
Cloud computing offers cost savings, because users don't have to invest
capital budget to purchase hardware and software, nor expend the operating
costs of electric power, space and cooling for the hardware and employee
costs of maintaining the hardware and software.
The maj... (more)
