Lecture Notes #10

Security Mapping - Recap Determine which resources you are planning to

move to the cloud Determine the sensitivity of the resources to risk Determine the risk associated with the particular

cloud deployment type (public, private, or hybrid models) of a resource

Take into account the particular cloud service model that you will be using

If you have selected a particular cloud provider, you need to evaluate its system to understand how data is transferred, where it is stored, and how to move data both in and out of the cloud

Adopting Mobile Cloud Applications

One application on cloud can be accessed by multiple types of clients.

Mobile cloud computing A model where processing is done in the cloud,

data is stored in the cloud, mobiles device serves as a presentation platform or a display

Advantage of cloud apps to mobile cloud Thinner devices -> less processing, consume

less power, and have better battery life Avoidance of vendor lock-in.

8

Adopting Mobile Cloud Applications (2)

Customized clients and GUIs for each specific type of client. e.g., Featured phones with light weight

operating systems. Smart phones with sophisticated

operating systems. e.g., iOS, Android, Windows Mobile, Symbian.

Less processing power, memory and storage but needs to be aware of bandwidth and display resolutions.

Mobile Web Services

Mobile web service are those in which information is transferred between applications (browser) and services over the internet.

Can make use of specific information about the context of the device and its users. Physical context Logical context

14

SOA Approach to processing requests using contextual data from mobile users

15

Service Discovery

Web services are useful only if they can be discovered by mobile devices and accessed by mutually supported protocol.

WS-Discovery from OASIS Standard WSDL (Web Service Description

Language) UDDI (Universal Description, Discovery,

and Integration) SOAP (Simple Object Access Protocol)

16

Mobile Web Services (2)

Mobile interoperability needs to be addressed in terms of Variable screen size and resolution. Slow network transmission. Different methods of navigation through

the interface. Vendor lock-in

Exclusion of support for certain file types such as PDF, and cookies, and technologies such as Adobe Flash.

Onerous transmission costs.17
