INTRODUCTION

Cloud computing is the use of computing resources (hardware and software)that are delivered as a service over a network (typically the Internet). The namecomes from the use of a cloud-shaped symbol as an abstraction for the complexinfrastructure it contains in system diagrams. Cloud computing entrusts remoteservices with a user’s data, software and computation.

1.1 HistoryThe origin of the term cloud computing is obscure, but it appears to derive fromthe practice of using drawings of stylized clouds to denote networks in diagramsof computing and communications systems.

• In the 1990s, telecommunications companies who previously offered pri-marily dedicated point-to-point data circuits, began offering virtual privatenetwork (VPN) services with comparable quality of service but at a muchlower cost. By switching traffic to balance utilization as they saw fit, theywere able to utilize their overall network bandwidth more effectively. Thecloud symbol was used to denote the demarcation point between that whichwas the responsibility of the provider and that which was the responsibilityof the users. Cloud computing extends this boundary to cover servers aswell as the network infrastructure.

• The underlying concept of cloud computing dates back to the 1950s; whenlarge-scale mainframe became available in academia and corporations, ac-cessible via thin clients / terminal computers. Because it was costly to buya mainframe, it became important to find ways to get the greatest return onthe investment in them, allowing multiple users to share both the physicalaccess to the computer from multiple terminals as well as to share the CPU

time, eliminating periods of inactivity, which became known in the industryas time sharing.

• John McCarthy opined in the 1960s that ”computation may someday be or-ganized as a public utility.” Almost all the modern-day characteristics ofcloud computing (elastic provision, provided as a utility, online, illusion ofinfinite supply), the comparison to the electricity industry and the use ofpublic, private, government, and community forms, were thoroughly ex-plored in Douglas Parkhill’s 1966 book, The Challenge of the ComputerUtility.

• In early 2008, Eucalyptus became the first open-source, AWS API-compatibleplatform for deploying private clouds.

• In early 2008, OpenNebula, enhanced in the RESERVOIR European Commission-funded project, became the first open-source software for deploying privateand hybrid clouds, and for the federation of clouds. In the same year, ef-forts were focused on providing quality of service guarantees (as requiredby real-time interactive applications) to cloud-based infrastructures, in theframework of the IRMOS European Commission-funded project, resultingto areal-time cloud environment.

• By mid-2008, Gartner saw an opportunity for cloud computing ”to shapethe relationship among consumers of IT services, those who use IT ser-vices and those who sell them” and observed that ”organizations are switch-ing from company-owned hardware and software assets to per-use service-based models” so that the ”projected shift to computing... will result indramatic growth in IT products in some areas and significant reductions inother areas.

• On March 1, 2011, IBM announced the Smarter Computing framework tosupport Smarter Planet. Among the various components of the SmarterComputing foundation, cloud computing is a critical piece.

• In 2012, Dr. Biju John and Dr. Souheil Khaddaj describe the cloud as a vir-tualized, semantic source of information: ”Cloud computing is a universalcollection of data which extends over the Internet in the form of resources(such as information hardware, various platforms, services etc.) and formsindividual units within the virtualization environment. Held together byinfrastructure providers, service providers and the consumer, then it is se-mantically accessed by various users.”

1.2 Types of cloudsThere are three types of clouds- Public cloud, Private cloud and Hybrid cloud.

1.2.1 Private CloudPrivate Clouds refer to internal data centers of a company or other organization. APrivate Cloud is fully owned by a single company who has total control over theapplications run on the infrastructure, the place where they run, and the people ororganizations using it — simply over every aspect of the infrastructure. A PrivateCloud relies on virtualization of an organization’s existing infrastructure, leadingto benefits such as increased utilization.

The key advantage of a Private Cloud is to gain all advantages of virtualization,while retaining full control over the infrastructure.

1.2.2 Public cloudA Public Cloud is data center hardware and software run by third parties, e.g.Google and Amazon, which expose their services to companies and consumers viathe Internet. Public Cloud is not restricted to a limited user base: it is made avail-able in a pay-as-you-go manner to the general public. Thus, Clouds can addresstwo type of customers: either end consumers on the B2C market or companies onthe B2B market.

1.2.3 Hybrid CloudHybrid Clouds combine Public and Private Clouds and allow an organization toboth run some applications on an internal Cloud infrastructure and others in a Pub-lic Cloud. This way, companies can benefit from scalable IT resources offered byexternal Cloud providers while keeping specific applications or data inside thefirewall. A mixed Cloud environment adds complexity regarding the distributionof applications across different environments, monitoring of the internal and exter-nal infrastructure involved, security and privacy, and may therefore not be suitedfor applications requiring complex databases or synchronization.

Storage with a great deal of promise, aren’t designed to be high performingfile systems but rather extremely scalable, easy to manage storage systems.They use a different approach to data resiliency, Redundant array of inex-pensive nodes, coupled with object based or object-like file systems anddata replication (multiple copies of the data),to create a very scalable stor-age system.

4. Imran Khan, Habib-ur Rehman, Zahid Anwar:“ Design and Deploymentof a Trusted Eucalyptus Cloud”. In IEEE , 4th International Conferenceon Cloud Computing 2011. Eucalyptus is an open source cloud computingsoftware framework that provides cloud based services called Infrastructureas a Service (IaaS). IaaS allows users to run and control entire virtual ma-chines on cloud Infrastructure. One of the main security and privacy issuesin cloud Infrastructure such as Eucalyptus is to ensure the integrity and con-fidentiality of user data and computation. This paper presented a design andDeployment of a Trusted Eucalyptus cloud based on TPM architecture. Thedesign of Trusted Eucalyptus guarantees to the users that their virtual ma-chines are run on only high integrity cloud nodes. This paper also showsthat Trusted Eucalyptus cloud is practical in terms of performance.

5. Liutong Xu, Jie Yang: “A MANAGEMENT PLATFORM FOR EUCALYP-TUS BASED IAAS. Proceedings of IEEE CCIS 2011.

In this paper IaaS management platform based on Eucalyptus, which usesLibvirt management library, SNMP (simple network management protocol)and VMM (Virtual Machine Monitor) to get more abilities to manage andmonitor the cloud. This platform provides some new features which canmanage and monitor resources and VM status in the cloud environment andgive a good user experience. Papaya platform is proposed in this paperwhich provides a convenient way to manage the IaaS cloud and providesmany monitoring features to monitor virtual resources and the VMs statusin the cloud. Their model can manage the IaaS based on Eucalyptus, col-lect both the real-time working nodes static and dynamical information andVMs information running on the node, which can provide a better referencefor resource discovery, resource scheduling and load balancing and billingthe use of resources and can be helpful to ensure the IaaS clouds stability.On the basis of this, more works like monitoring the applications (Services)in the cloud. And then according to all these monitoring data, Designingmore efficient and more reliable management platform to manage and mon-itor the cloud can be done.

6. Adeela Waqar, Asad Raza, Haider Abbas:“ User Privacy Issues in Eucalyptus-


A Private Cloud Computing Environment”. In International Joint Confer-ence of IEEE TrustCom-11/IEEE ICESS-11/FCST-11 (2011).

In this paper, they simulated some of the potential attacks to users data andmetadata stored in Eucalyptus database files in order to provide the intendedreader with the requisite information to be able to anticipate the grave conse-quences of violation of cloud users data privacy. Security analysis of cloudpertinent data privacy of users cloud resident data and metadata. It identi-fies the potential attack sources, prospective attacks originating from thesesources and possible measures to prevent these conceivable attacks. Duringthis research, it was tried to achieve a detailed exploration of the spectrumof realizable attacks using WALRUS storage service as an example. As aresult of investigating this paradigm, it was observed that a reasonable num-ber of areas need substantial level of security, in order to ensure preservationof users data privacy and thus guarantee the sustainability of an effectivelyoperational private cloud system.

7. Christian Baun, Marcel Kunze: “Building a Private Cloud with Eucalyp-tus”.

This paper compares the performance of a cloud computing infrastructureimplemented with Eucalyptus to Amazon EC2/S3/EBS and includes thelessons learned while building up a private cloud with Eucalyptus.Eucalyptusis an interesting product to build private cloud infrastructures for R and D.The performance of such an installation with commodity hardware is satis-fying for most common scientific applications. Already now a large num-ber of open source tools exist for cloud management. As also other cloudsoftware providers start to implement Amazon AWS as a cloud computinginterface AWS has the potential to become a de facto standard for cloudcomputing infrastructure services.

8. Huioon Kim, Hyounggyu Kim, and Youngjoo Chung:“ Building a Eucalyp-tus Cloud Automatically with Fully Automatic Installation”. 978-1-4673-0089-6/12 IEEE 2012.3pt In this paper, they presented the fully automatic scheme to build a privatecloud based on Eucalyptus with FAI. Using this scheme, they could easilybuild our own private clouds that have various numbers of nodes from 1 to15. That is, with this method, one can easily build his/her own on-premisecloud and scale up and down from a small size cloud to a large-scale cloudwith minimum effort whenever he/she wants. Also, the increment of thetotal build time measured depending on the number of nodes was relativelysmall in our experiment, which means that this scheme has good scalability.The total build time for 15 nodes took only about 15 minutes, so they are


expecting that even a large-scale cloud can be built in a short time with thisfully automatic installation method.

9. Dr.G.R.Karpagam, J.Parkavi:“Setting up of an Open Source based PrivateCloud”. IJCSI International Journal of Computer Science Issues, Vol. 8,Issue 3, No. 1, May 2011.3pt This paper describes the configuration of a private cloud using Euca-lyptus. Eucalyptus an open source system has been used to implement aprivate cloud using the hardware and software without making any modi-fication to it and provide various types of services to the cloud computingenvironment. They concluded that cloud computing is an everlasting com-puting environment where data are delivered on-demand to authenticateddevices in a secured manner and users utilize a shared and elastic Infras-tructure. This paper briefly explains the set up of a private cloud in a clusterbased environment using open source technologies like Eucalyptus, KVM,and euca2ools. The virtual machine images are available in the cloud andupon user request; its instances are created and run. Services were includedsuccessfully and made available to the user. The current implementationof this paper provides Infrastructure as a service (IaaS) and Software as aService (SaaS).

Proposed Architecture

6.1 Architecture of Ubuntu Enterprise Cloud(UEC)

6.1.1 Node Controller (NC)A UEC node is a VT enabled server capable of running KVM as the hypervisor.UEC automatically installs KVM when the user chooses to install the UEC node.The VMs running on the hypervisor and controlled by UEC are called instances.Eucalyptus supports other hypervisors like Xen apart from KVM, but Canonicalhas chosen KVM as the preferred hypervisor for UEC.

Node Controller runs on each node and controls the life cycle of instancesrunning on the node. The NC interacts with the OS and the hypervisor runningon the node on one side and the Cluster Controller (CC) on the other side. NCqueries the Operating System running on the node to discover the node’s physicalresources the number of cores, the size of memory, the available disk space andalso to learn about the state of VM instances running on the node and propagatesthis data up to the CC. Functions:

• Collection of data related to the resource availability and utilization on thenode and reporting the data to CC.

• Instance life cycle management.

6.1.2 Cluster Controller (CC)CC manages one or more Node Controllers and deploys/manages instances onthem. CC also manages the networking for the instances running on the Nodesunder certain types of networking modes of Eucalyptus. CC communicates withCloud Controller (CLC) on one side and NCs on the other side. Functions:

17

• To receive requests from CLC to deploy instances

• To decide which NCs to use for deploying the instances on

• To control the virtual network available to the instances

• To collect information about the NCs registered with it and report it to theCLC.

6.1.3 Walrus Storage Controller (WS3)WS3 provides a persistent simple storage service using REST and SOAP APIscompatible with S3 APIs. Functions:

• Storing the machine images

• Storing snapshots

• Storing and serving les using S3 API

WS3 should be considered as a simple file storage system.

6.1.4 Storage Controller (SC)SC provides persistent block storage for use by the instances. This is similar tothe Elastic Block Storage (EBS) service from AWS. Functions:

• Creation of persistent EBS devices

• Providing the block storage over AoE or iSCSI protocol to the instance.

• Allowing creation of snapshots of volumes.

6.1.5 Cloud Controller (CLC)The Cloud Controller (CLC) is the front end to the entire cloud infrastructure.CLC provides an EC2/S3 compliant web services interface to the client tools onone side and interacts with the rest of the components of the Eucalyptus infrastruc-ture on the other side. CLC also provides a web interface to users for managingcertain aspects of the UEC infrastructure. Functions:

• Monitor the availability of resources on various components of the cloudinfrastructure, including hypervisor nodes that are used to actually provisionthe instances and the cluster controllers that manage the hypervisor nodes17


• Resource arbitration - Deciding which clusters will be used for provisioningthe instances Monitoring the running instances

• Monitoring the running instances

In short, CLC has a comprehensive knowledge of the availability and usage ofresources in the cloud and the state of the cloud.
