OPEN STACK - SEPTEMBER 2014 2

Abstract

To implement Infrastructure as a Service on our provided system in order to launch a particular

instance onto it. For achieving this we used Open Stack cloud software.

Purpose of the Project

The purpose of the project is to use Open Stack cloud software to deploy required instances on the

cloud. But the main aim of the project was to understand the working of the software as to how

the images are loaded into the software and how new instances or applications can be deployedinto the cloud.

What is Open Stack?

Open Stack allows users to deploy virtual machines and other instances which handle different

tasks for managing cloud environment. It makes horizontal scaling easy which means it can easilyexecute tasks that can benefit user by running concurrently. It provides Infrastructure as a Service

(IaaS) solution. Most importantly Open Stack is an open source software which means that anyone

who wishes to make changes within the code is allowed to do so.

How is Open Stack used in cloud environment?

Cloud is all about providing computing for end users in a remote environment where the actual

software runs as a service on reliable and scalable servers rather than on each end users computer.Open Stack is considered Infrastructure as a Service (IaaS). Providing infrastructure means that

Open Stack makes it easy for users to quickly add new instance upon which cloud components canrun. Typically, the infrastructure then runs a platform upon which a developer can create softwareapplications which are delivered to the end users.

Requirements

Minimum 4 GB of RAM. But above 4 GB is recommended.

A minimum of 50 GB hard disk space for installing all the components.

A proper bandwidth of internet for streaming all the updates and downloading the components.

64 bit of operating system.

How we intended to do it at start?

At first we installed Devstack in order to get a brief idea of what were the components of Open

Stack. Later on we carried out the installation of Red Stack in order to integrate Trove with

devstack. Trove will integrate the database to all the components of Open Stack.

Later on we tried to build a cluster of all the components of Open Stack. For that we

installed UBUNTU server 14.04 in one of the machine. We tried to connect the other machines bymaking those nodes of the server. For that we used MaaS (Metal as a Service). The reason that wetried to use MAAS is that it makes it easy to set up the hardware on which to deploy any service.By using a simple web interface we can add, commission, update and recycle the servers. As the

need changes we can respond rapidly by adding new nodes and dynamically re-deploying them

between services. The next step we concentrated on deploying the Open Stack by using JUJU.

JUJU basically scales the infrastructure needed to deploy Open Stack using MaaS.

What were the limitations faced with MaaS?

Lack of continuous bandwidth resulted in the network downtime which caused the failure of theoperating system images to be downloaded on the nodes that we created. As a result of this therewas the failure of PXE booting the systems.

What we intended to do on limitation to creating the

cluster of the components?

We intended to install all the Open Stack components in our machine in order to launch our desired

instances into the cloud using trove-integration using the RedStack.sh script. Trove is the database

as a service open source project for Open Stack. Trove is to provide scalable and reliable clouddatabase as a service provisioning functionality for relational and non-relational database engines

and to improve its full featured and extensible open source framework.

What are the steps of installation for Trove?

Step 1:The first thing that is prerequisite for installation of Open Stack is having a stable version of

UBUNTU which can be either 12.04 or 14.04. In our project we have used UBUNTU-14.04.

Step 2:Secondly we need to update UBUNTU for installation of the latest packages by installing usingthe following syntax $apt-get update.

Step 3:Next we have to clone in the Git repository for streaming trove-integration script from the

repository using the syntax $ apt-get install git-core y and $git clone

https://github.com/openstack/trove-integration.git

Step 4:Next we have to go into the scripts directory using the following syntax$ cd trove-i

ntegration/scripts/

Step 5:Installing all the dependencies and install trove via devstack. The syntax for installing the dev

stack is$./redstack install

Step 6: Next we have to initialize trove to add the image to trove using the following syntax

$./redstack kick-start mysql

Step 7:Starting the open stack services by using the $./redstack start

Limitations faced during and after installation

There were limitations too that we faced while installing the Trove through RedStack. The first

limitation that we faced was trying to install 64 bit MySQL plugin through Trove while the Linux

distro was 32 bit. Issue with the console on launch of an instance. SSH of Ubuntu and Fedoraimages were not possible.

Launching an instance

We were able to launch the Cirros instance which is up and running. SSH of Cirros instance wassuccessful.

Conclusion

The main concern was with the installation of Open Stack cloud components which is successfullyinstalled, up and running. At the end of the project we have been able to understand the functioning

of Open Stack properly which was the primary goal of the project.

What we achieved at the end of the project?

There were many optimistic evaluations by the cloud team at the end of the project

We were able to get the images of Fedora and Ubuntu along with Cirros up and running.

We were able to deploy the database instance on MySQL running under the Ubuntu instance. We got a vivid idea of how to create a cluster using MaaS and JUJU.

We were able to differentiate the functioning of each and every components that we have used

in our project.

We got the idea of how Infrastructure as a Service is deployed using Open Stack.
