The Presenters & the Tutorials. Mobile Computing – The Future is in Your Hands. By Andrew.K Leong. General Manager, Hycare Systems, Inc. 1 Introduction. Mobile computing Tutorial pdf, Mobile computing online Tutorial with reference manuals and examples. Mobile Computing is a human-computer interaction that allows transmission of data, voice and video via a computer or any other wireless device without.

It offers computational resources on demand as a metered service. Cloud computing, grid computing, and managed IT services are based on the concept of Utility computing.

We can broadly divide the cloud architecture into two parts: Front End Back End Each of the ends are connected through a network, usually via Internet. It consists of interfaces and applications that are required to access the cloud computing platforms, e. It consists of all the resources required to provide cloud computing services.

It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc.

Important Points It is the responsibility of the back end to provide built-in security mechanism, traffic control and protocols. The server employs certain protocols, known as middleware, helps the connected devices to communicate with each other.

It allows to share the single physical instance of cloud resources between several tenants. It allows to connect cloud services over the Internet.

It is also possible to deliver network as a utility over the Internet, i. If one of the storage resource fails, then it can be extracted from another one which makes cloud computing more reliable.

But it is not possible to satisfy the demand with single resource or server. Therefore, there must be transparency in resources, load balancing and application, so that we can scale them on demand. So, application delivery solution is need to be scalable which will require the virtual infrastructure such that resource can be provisioned and de-provisioned easily. Also the control node, a entry point in mega data center also needs to be secure.

The Private Cloud is operated only within a single organization. However, It may be managed internally or by third-party.

Benefits There are many benefits of deploying cloud as private cloud model. Non-critical activities are performed using public cloud while the critical activities are performed using private cloud.

Benefits There are many benefits of deploying cloud as hybrid cloud model. It shares the infrastructure between several organizations from a specific community. It may be managed internally or by the third-party.

Sharing Between Organizations Community cloud provides an infrastructure to share cloud resources and capabilities among several organizations. ISSUES Since all data is housed at one location, one must be careful in storing data in community cloud because it might be accessible by others. It is also challenging to allocate responsibilities of governance, security and cost. Moreover, these resources are accessed by the customers as if they own them.

Flexible and Efficient renting of Computer Hardware. Portability, Interoperability with Legacy Applications.

Consumer issues administrative command to virtual machines they owned to start web server or installing new applications. The consumer has to pay based the length of time a consumer retains a resource.

Cloud Computing Tutorial

Also with administrative access to virtual machines, the consumer can also run any software, even a custom operating system. For example, network applications such as web server, server that normally runs on consumer-owned server hardware can also be run from VMs in IaaS cloud.

It also have some specific issues associated with it. However, the provider can automatically update such VMs, but this mechanism is hard and complex. Business Skills. Digital Marketing Skills.

Mobile Computing Classification. These key factors are: IT management simplification operation and maintenance cost reduction business mode innovation low cost outsourcing hosting high service quality outsourcing hosting.

In this step, a strategy document is prepared according to the conditions a customer might face when applying cloud computing mode.

Cloud Computing Tactics Planning Phase This step performs analysis of problems and risks in the cloud application to ensure the customers that the cloud computing successfully meet their business goals.

The success of applying cloud computing mode depends on these non-functional factors. Cloud Computing Deployment Phase This phase focuses on both of the above two phases.

They must have to ensure the quality of services. These technologies are listed below: Virtualization Service-Oriented Architecture SOA Grid Computing Utility Computing Virtualization Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants customers.

It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded.

Service-Oriented Architecture SOA Service-Oriented Architecture helps to use applications as a service for other applications regardless the type of vendor, product or technology.

Therefore, it is possible to exchange of data between applications of different vendors without additional programming or making changes to services. These computer resources are heterogeneous and geographically dispersed. Grid Computing breaks complex task into smaller pieces. These smaller pieces are distributed to CPUs that reside within the grid. It offers computational resources on demand as a metered service. Cloud computing, grid computing, and managed IT services are based on the concept of Utility computing.
