IntroductionMobile Cloud Computing (MCC) which combines mobile computing and cloud computing. It refers to an infrastructure where the data storage and data processing can happen outside of the mobile device.

MotivationMobile devices are becoming an essential part of human life. (e.g., Smartphone, tablet PCs, etc) Mobile devices still lack in resources.MCC overcome the mobile challenges (battery lifetime, processing power, availability)Integrate mobile device with cloud computingAccessing to multimedia and sensors data.MCC provide Efficient and effective application Real-time response.Minimum communication cost with mobile platform Limited computation overhead

Cloud ComputingCloud Computing provider of pooled network resources such as CPU, RAM, Storage and software over the web. These services are easily provides and released on demand.

10GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

Cloud Computing is a combination of virtualization (one computer hosting several virtual servers), automated provisioning (servers have software installed automatically) distributed computing and Internet connectivity technologies to provide the service. 10

Cloud Computing service models Infrastructure as a Service (IaaS):Platform as a Service (PaaS).Software as a Service (SaaS).


Iaas:Provides infrastructure such as computer instances, network connections, and storage so that user can run any software or operating system.Paas:Provides the ability to deploy applications through a programming language or tools supported by the cloud platform provider.Saas:Provides the ability to use the software in a cloud environment11

Cloud Computing deployment models

Private Cloud.Public Cloud. Hybrid Cloud.Community Cloud12GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

Private Cloud which the services and infrastructure are maintained on a private network.Public Cloud which the services and infrastructure are provided off-site over the Internet. Hybrid Cloud which is composition of both public and private clouds.


BUILD PRIVATE CLOUD(By open source software)

13GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

Reasons for Building a Private CloudThe better utilization of hardware The ability to quickly provision capabilitiesThe ability to easily provide continuity of application.

B. Categories of Infrastructure for a Private Cloud

Before Selection the private cloud infrastructure software we need to understand the component of private cloud infrastructure

Virtualization: technology provides the hypervisor software, which allows multiple instances of guestoperating systems to run concurrently on the same physical server. Storage technology: such as storage area networks (SANs), can provide the underlying persistent storage for the data center. Security such as identity management and virtual firewalls. Provisioning, management, and metering tools provide the ability to deploy virtual operating systems, services, and applications.13

OpenStack (IaaS)OpenStack: Open source cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter.

14GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

The reason of selection openStack:a) Provide scalable, elastic cloud computing for private cloud. b) Simple to implement and massively scalable Change. c) Managed all resources through a dashboard that gives administrators control while empowering their users to provision resources through a web interface. d) Excellent for large deployments. e) The user can have good knowledge to the used component only not all openstack components.

2) OpenStack Component And Architecture : Dashboard ("Horizon"): provides a modular web based user interface for all the OpenStack services. Identity ("Keystone"): provides authentication and authorization Image ("Glance") : provides a catalog and repository for virtual disk images. Compute ("Nova") : provides virtual servers upon demand. Networking ("Neutron"): Enables network connectivity as a service among interface devices managed by other OpenStack services, usually Compute Service. Block Storage ("Cinder "): A service that manages persistent block storage volumes for virtual machines. Object Storage ("Swift "): provides object storage. It allows you to store or retrieve files.14

OpenShift (PaaS)OpenShift:Open Source Software to PaaS that enables developers to build and deploy web applications without constraints.

15GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

The reason of selection OpenShift.

Open Source Software and run on top of Openstack private cloud infrastructureOpenshift provide programming languages and frameworks Java, Ruby, and PHP. It also provides integrated developer tools to support the application lifecycle,including Eclipse integration, JBoss Developer Studio. Easy to deploy and provide great documentation for the services.Provide standard languages , IDE Integration , Built-in Database Services and responsive Web Console and application portability.


Cloud Service models IaaS vs PaaSExperiment Goal: Evaluate application deployment in deferent cloud service models. Experiment Description: retrieve the data of ten persons from MySQL database.{"personData":[{"address":"nasrcity","age":"20","city":"Cairo","country":"Egypt","description":"Marwa has traditional and practical personality. she is hardworking and has leadership. ","email":"", "gender":"female", "image":" ","job":"Senior Software Engineer ","name":"Marwa","telephonNumber":"0245358249329 "}]}

Experiment Result:

The platform as a service module adds a little overhead on response time. The overhead is mainly caused by managing and monitoring development software.16GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

Mobile cloud Computing Architecture Mobile Network Cloud Computing

Mobile Device (with developed Application ) 18GPU_MCC Marwa Ayad, ICEAC 2015, Cairo

In this architectureThe cloud resource is placed in a remote centralized cloud infrastructure.

The mobile devices access the backbone network via WiFi access points (APs) or 3G/4G cellular networks.

The Requests and information of Mobile users are transmitted to the central processors that are connected to servers providing mobile network services.

After that, the requests are delivered to a cloud through t
