ICT Infrastructure: Cloud, SOA, and E-Government Architecture

This assignment delves into the intricacies of managing ICT infrastructure, specifically focusing on cloud-oriented e-government architecture (COEGA). It examines how Service-Oriented Architecture (SOA) facilitates high-quality service delivery by leveraging reusable infrastructure components and enhancing information sharing. The assignment also explores the role of SOA in managing Service Level Agreements (SLAs) to ensure quality of service from cloud providers, detailing features like virtualization, service reuse, and VM monitoring. Furthermore, it addresses key issues in developing e-government architectures, such as achieving technical, semantic, and organizational interoperability through data exchange, data normalization, and data security. The implementation of SOA and cloud-oriented services is analyzed for its ability to enhance interoperability, increase agility, and improve service access, ultimately minimizing risks and optimizing service request management. This comprehensive analysis provides insights into the critical aspects of modern e-government infrastructure and the benefits of adopting SOA and cloud technologies.

Managing ICT Infrastructure

Question 1 Cloud Oriented e-Government Architecture (COEGA)
1. Ways in which adoption of a Service-Oriented Architecture (SOA) facilitate the delivery of a
high Quality of Service in this e-Government architecture
 Service-oriented architecture (SOA)is basically the style of the software design under
which the services are being offered to other components through application software or
through the communication protocol.
 SOA has helped in provided infrastructure components like service network devices and
many more as building blocks of COEGA as it has provided COEGA discovery and
reusability of e-government services with the help of re-usable SOA infrastructure.
 This has helped in increasing the reusability of the infrastructure over the internet due to
which efficiency and effectiveness and service quality of service has been improved.
 This has further helped COEGA to enhance their overall sharing of information,
information exchange among various government organizations.
 So, it can be said that SOA has helped in facilitating COEGA in facilitating high service
quality. SOA helps in reusing computing components and cloud computing enables this
technology to become more flexible for architectures that are build on SOA solutions.
2. features of SOA that facilitate the management of SLAs for ensuring the quality of service
from the cloud computing providers
 Service-level agreement (SLA) is generally the contract between service provider as well
as its external or the internal customers which documents that what services will the
provider will furnish as well as defines services standards.
There are many features of SOA that has helped in facilitating SLA management, such as:
 Virtualization feature of SOA has enhanced VM monitoring feature.
 Service reuse feature of SOA has helped in enhancing service requires examining feature so
that interface between service providers and end users is maintained and service request from
end users can directly be send to end users. This has further helped in maintaining service
repository which is sued to provide service to the end users.
Question 2
Adoption of a Service-Oriented Architecture facilitating the delivery of a high Quality
of Service in e-Government architecture.

 The quality of service can be achieved by determining the requirement of functional as well
as non-functional factors.
 The service description describes the functionality of the users requirements. Therefore, in
the case of cloud service the considerable amount of non-functional quality attributes are
comparatively very high.
 Security, reliability, flexibility, usability, time and performance are the applications of
workflow which is based on the most common quality of service requirements. There are
basically two sides of quality of service which includes:
 from the view of government for providing the most appropriate e government services, the
government must have the capacity to fulfil the levels of service demands.
 From the view of customer the quality of service during the usage of e government service by
the citizen of the country.
2. Adoption of a Service-Oriented Architecture by cloud computing providers for facilitating the
 management of SLAs for ensuring the quality of service.
 For any on using cloud computing the aspects of service level agreements are very important.
When an individual uses cloud computing the service level agreement assigns the following
terms .
 The need of service oriented architecture facilitate the management of Service level
agreement in the following terms.
Service request examiner and admission control
When a service request if submitted it interprets the request submitted for quality of service.
Pricing
The prising serve as the channel for the management of demand and supply for the computing
resources of the data of data centre.
Accounting
For computing the final cost that the customer has to bear is recorded on the usage of the service
by customer on demands.
VM monitor
This monitors the virtual machines' availability as well as their resource entitlements.
Dispatcher

Begin the process of accepted services request on allocation of virtual machines.
Service Request Monitor
It monitors the progress of executions of service request.
Question 3 Issue in the development of the e-government architecture
1. Issue that would be required to be addressed in order to achieve a high degree of technical,
semantic and organization interoperability
 Achieving the high degree of technical as well and organizational interoperability is
essential and thus encompasses a variety of issues.
 Issues that would be required to be addressed in order to achieve higher degree of
organizational, technical and systematic Interoperability are: data exchange issue, data or
message formats for achieving structural operability.
 Data normalization is another issue that is required to be addressed in order to achieve
higher degree of systematic interoperability.
 Data security, privacy and compliance is important to be focused as these issues plays a
vital role in achieving higher degree of systematic, technical and organizational
interoperability.
2. Ways in which implementation of a service-oriented architecture, together with the use of
cloud-oriented services, enhance the achievement of a high level of interoperability in this
architecture
 SOA has helped in increasing the reusability of infrastructural components and cloud
computing has further helped in increasing the flexibility of all the services that are
provided through cloud. In other words, together SOA and cloud computing has helped in
achieving higher level of agility.
 It has further helped in removing all the barriers of cloud computing that were faced by
the customers in accessing their desired service.
 It has helped in increasing access to reusable web services over internet which has further
helped in achievement of higher level of interoperability.
 It has further helped in decreasing risks associated with cloud computing services.
 It has also helped in improving Service Request Monitor which helps in monitoring
service request execution. Other than this it has also helped in dividing bigger problems

into smaller service sets due to which problems related to it are solved easily.
 It divides service registry into two service consumers and service providers so that
services can be found, registered and invoked in an easy manner.
