Session Presented at 1st IndicThreads.com Conference On Mobile Application Development held on 19-20 November 2010 in Pune, India

Speaker: Romin Irani

Abstract:
Mobile applications typically present the client side of a hosted application be it an enterprise app or a web application. This session aims to bridge and cover how you can power your mobile applications from the Cloud. The presentation will demonstrate how you can power both a native mobile application (Android) and a mobile web application (HTML based) from the Cloud via REST based HTTP Services.

The session will look at:
a) Advantages of using the cloud for mobile apps, with Google App Engine as an example. We shall build and deploy a simple Google App Engine application in the Cloud live.
b) Develop a simple Android Native Application that is powered by the services developed in (a). Demonstrate the same for a Mobile Web Application
c) Cover WURFL and how the device database can help you serve different content based on the capabilities of the mobile device that accesses your application.

Everyone has an opinion on what it is In this session, you will see what my opinion is! Actually not, what you will be given is a non-opinionated journey into what Cloud Computing is today minus the hype Along the way, we will do the following: Demonstrate a real Cloud Computing environment looks at from a developer perspective Code an application from scratch and deploy it See how you can write mobile applications that are driven by the services in your cloud application
On Demand Self Service A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed without requiring human interaction with each service's provider. Ubiquitous network access Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). Location independent Resource Pooling The provider's computing resources are pooled to serve all consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. The customer generally has no control or knowledge over the exact location of the provided resources. Examples of resources include storage, processing, memory, network bandwidth, and virtual machines. Rapid Elasticity Capabilities can be rapidly and elastically provisioned to quickly scale up and rapidly released to quickly scale down. To the consumer, the capabilities available for rent often appear to be infinite and can be purchased in any quantity at any time. Pay Per Use Capabilities are charged using a metered, fee-for-service, or advertising based billing model to promote optimization of resource use. Examples are measuring the storage, bandwidth, and computing resources consumed and charging for the number of active user accounts per month. Clouds within an organization accrue cost between business units and may or may not use actual currency. Cloud Software as a Service (SaaS) The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure and accessible from various client devices through a thin client interface such as a Web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. Cloud Platform as a Service (PaaS) The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created applications using programming languages and tools supported by the provider (e.g., java, python, .Net). The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, or storage, but the consumer has control over the deployed applications and possibly application hosting environment configurations. Cloud Infrastructure as a Service (IaaS) The capability provided to the consumer is to rent processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly select networking components (e.g., firewalls, load balancers).
IaaS  PaaS  SaaS
Last Point :You have to understand that what has happened is that via a credit card, you can now purchase compute cycles, create virtual machines and so on. And you do not need a full time service contract or plan for it in advance
Disadvantages: Learning a new programming model Constant monitoring, tweaking, etc as per your usage.
Free Quota : Set by System Billing : Depends on the User Free Quota should be enough for most applications to get started Monitor the application usage to understand how much resources your application is using
Current approach is built using HTML5/JavaScript for high end mobile browsers. This approach can be extended for lower category of mobiles using XHTML-MP with multiple CSS for different mobiles. Approach plans to leave the older generation of mobiles using WML.
Single code base approach (except multiple CSS for XHTML-MP approach) For smart phones, CSS and JavaScript is used to perform Ajax like calls, thereby improving the application responsiveness.
The native application has been built on iPhone OSv3.2 and Android v1.6 for demo purposes. This would be required to be built on all target devices. In this approach we could use the different mobile related features using the same server side code.
Support is there for HTTP APIs in all Mobile OS.
