What is the main reason why many of the independent exchanges developed in the early days of e-commerce failed?

-

 The main reason is they failed to attract enough players to achieve liquidity. That is, the number of buyers and sellers in the market, the transaction volume, and the size of the transactions were insufficient to sustain a profit.

Short note on E-Government Architecture

-

1)  Presentation layer The presentation layer identifies and describes the system users, who require access to government information at different capacities, and the channels through which information can be accessed.  During system development, one is required to explicitly identify the government user, the system is intended to serve, and also the means through which this information is to be accessed so that the system can be tailored to meet these requirements. It manages the user’s interface with the system. If a pro- project is to be successful, different stakeholders need to be identified at the beginning, involved in the initial stages and kept involved throughout development and implementation. 2) E-government layer E-government public services utilize very specialized applications that are only available to certain agencies and not all agencies participating in the consortium. The main goal of the e-government layer is to achieve a government that;  does not as...

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

 CLOUD COMPUTING REFERENCE MODEL The cloud computing reference model is a general high-level architecture and is meant for a cloud computing reference architecture provided, which outlines the primary performer/actor and the understanding of the cloud computing needs, uses, features, and standards. An overview of the NIST primary players, as indicated in the figure below. Each performer is an entity that might be a person or a cloud computing activity and role. The NIST cloud computing reference architecture identifies five organization that takes part in a transaction or process and complete duties in cloud computing. 1. Cloud consumer:  The cloud consumer is the cloud computing service's most significant stakeholder. A cloud consumer is a person or organization who has a commercial connection with a cloud provider and consumes its services. A cloud consumer browses a cloud provider's service catalog, requests the right service, establishes service contracts with the cloud pr...
