ABSTRACT – Recent economic decline and further predicted decrease in certain countries in Europe have forced their governments into employing important measures to protect its economies. The government reduction in spending as part of her measures has indeed been proposed by the United Kingdom (UK). The UK Metropolitan Police (UMP), an arm of the government, has been hit by these cuts in capital allocations leading to reduction in its proposed budgets and expenditures. Hence an effective use and management of Information Communication Technology (ICT) and its resources while delivering efficient and better police service is of high importance to the UK Metropolitan Police. The Internet provides a more interactive and effective means of disseminating information within its users, but maintaining availability now pose a major challenge of complexity and scalability with increasing operational cost. Cloud Computing technology has helped overcome some of these challenges by making use of the internet and a remote resource centre to manage computer infrastructures, applications and allow users on-demand access to any of these services. Its scalability, simplicity, availability and flexibility do bring a better approach to police services. This research explores the different applications of cloud computing technology in improving Metropolitan police services while reducing their operational cost.
Keywords; Cloud computing, Information communication technology (ICT), UK Metropolitan Police (UMP), Police services.
I. INTRODUCTION
Cloud computing is an emerging
computer technology model in which end users have access to their files, basic
computing infrastructures and can define their own applications regardless of
their location via the internet. Its technology makes computer resources
scalable over the internet, giving users various options of subscriptions .The
technology makes these resources a utility to the end user which is cost
effective as users get to pay for only the amount of services utilized [1]. It
improves service delivery, enables business innovations and most service
providers define the technology to suit the type of services they render to
customers [2]. This paper introduces the basic understanding of cloud computing.
It describes the features expected of a cloud system, how the services are
deployed and the type of services that can be offered. It further gives an
overview of UMP, analyse some various problems associated with their ICT and
finally examines how cloud computing can be integrated into their ICT network;
ease the burden of increasing ICT innovations and advances while reducing its
overall cost on ICT.
II. DEFINITION
Gartner defined cloud computing
as “a style of computing where massively scalable Information Technology
enabled capabilities are delivered as a service to external customers using
internet technology” [3]. It is a web service which allows users the access to
resizable cloud storage capacity, virtual servers and computer applications and
software remotely [4]. The resources, applications and information which are
logically stored in the cloud are shared among users [5].
A.
Features Of
Cloud Computing
Figure1. Cloud Computing System
[1]
These features described by
figure 1 draws a generalized view of what is expected of a cloud system.
1. Broad
Network Access: a minor client or mobile device (iPad, smart phones and
PDAs) should have access to the resources in cloud as they seek them. Laptops,
computing systems all have access to the cloud network and it is independent of
their location. It also allows interoperability between various devices.
2. Measured
Services: each user is measured or charged by the amount of service
rendered to him with a flexible service plan.
3. On-Demand Self Service:
end users have hosted or stored application and major processing functions are
made
available to independent users based on their demand [1].
4. Rapid
Elasticity: cloud computing have the ability to expand its services and
adapt to frequent growing increase in demand for ICT and subsequent
innovations.
5. Resource Pooling:
cloud services make available resources to multiple end users. Some users can
have variable level (normal, optimum or premium) access to specific resources
which varies according to the terms of agreement or subscription plan between
the service provider and the end user [4].
It is important to note that the
cloud infrastructure which comprises of the hardware and software are the
devices that enable the above described features (NSIT). They can be deployed
to the users in different environment depending on the service agreed on.
B. Cloud Deployment
1. Public
Cloud: in this model the service provider makes available the resources to
an external user. The company owns, manages, maintains its infrastructure and
bears the operational cost. Profits are usually generated through advertisement
and some premium services [6].
2. Private
cloud: the service provider renders end users a virtual private network in
which they can host their own services. Both the provider and user coexist
within the same enterprise [2].
3. Hybrid Cloud:
A combination of both public and private
cloud forms a hybrid cloud. It describes a user who decides to utilize both
services from the same company.
4. Community Cloud: describes a
cloud in which certain community of end users from who share similar goals and
views have access and share particular cloud infrastructures [7].
The above described model gives
the user a way to define the architecture of his preferred cloud structure,
however the real services rendered to him does vary according to the need.
C. Cloud Service Delivery
Model
1. Infrastructure as a
Service (IAAS): a computer in the cloud! This service brings to the users a
personalized network structure based on a pay-as-you-use (resources) basis [1].
This provides a virtualized technology (virtual server) in which users define
their own applications and computer specifications Data storage capacity, CPU
speed, compute bandwidth, Operating System (OS) type are some of the defined
instances. Amazon EC2, IBM Smart Cloud and Go-Grid are some typical IAAS
services.
2. Platform as a Service
(PAAS): here the service is targeted for application developers. The
service provider renders to the developers an Operating
System, language debugger and
some other basic programming tools in the cloud. The service allows developers
to design their own applications remotely and deploy them to the cloud for
execution. All the program processing is handled by the cloud network. Examples
of such service are Google App Engine and Microsoft Azure.
3. Software as a Service (SAAS): SAAS describes a cloud service in which applications
and software’s hosted by service providers are made available to the users
through the internet which is accessible by a web browser. In SAAS presently,
the company provides the service freely to the users but actually users at the
other hand, render there information, time and interest area which is very
useful to interested companies.[1]
III. THE UK METROPOLITAN POLICE (UMP)
The British London police
popularly known as the UK Metropolitan Police was established in 1839 with
about 850 police officers and 406 civilian support staffs. Their primary
objective is to prevent and detect crime, punish offenders, protection of live
and property and maintain a unique, respective and interactive co-operation
with the community [8].
The structure of the UMP which
is headed by the Management Board (9 members) is made up of 3-Operational Units
(Op’s) and 4-Directorate. Each of these Units and Directorates has different
departments with specific roles. The Directorate of Information (DOI) is an arm
of the management board that is responsible for providing ICT services to the
grown (51,000 workforce) police officers and staffs [9]. Amongst part of its
(DOI) various responsibilities is the strategic ICT development within the UMP
which aims at integrating new technologies into police services while setting a
foundation for innovations and improvements [10]. The increasing economic
challenges faced in the present government and the force has deemed it
necessary for ICT management to be adaptive to cope with the underlining
trends.
The world is changing,
technologies are improving, more advanced innovations are emerging, the way of
life of people and where they live in are adapting to these changes with the
type of crimes committed different from that of earlier times. Hence, UMP
approach to these sensitive crimes does need to be significantly improved [11].
A. ICT Setbacks In Ump
ICT development is faced with
some drawbacks which were analysed through the type of delivery requirements
needed [11].
1. Effective Mode of Operation: a clear collaboration between the police operational
procedures and the experts with the right tool is a major issue which needs
improvement. These directly affect the frontline officers, inconsistencies and
disruptions in
real time operations due to some
unfavourable services agreements [10].
2. Information Accessibility & Quality of Service (QoS): the type
of ICT architecture makes it difficult for a universal file sharing mechanism
with minimal latencies in assessing data and information. Most of the Boroughs
have their own database, which is very useful due to it closeness but at times
this pose issues especially when retrieving in a congested network. Sometimes
information and data are entered multiple times; multiple authentication on the
same database needed giving rise to a larger database and cost of maintenance
[11].The frontline officers do experience some latency in retrieving
information about suspects, victims, etc. when on duty. This reduces the QoS of
the general Boroughs grid-like ICT network system.
3. Technological Flexibility: technology and
the services that ICT companies render have seen a remarkable increase and
further predicted rise. The demand for it keeps getting stronger making it more
competitive due to the rate and type of crime committed especially the upcoming
2012 Olympics. This variation is a major concern to the organizational
structure of the ICT in the UMP. Some online and mobile devices (internet)
access to police data and services can be limited by different technology
legacy agreement of various companies. It also raises a question of community
policing and flexibility of data access due to the competitive nature of these
agreement.
Figure 2. UMP Network System
B. The UMP Network System
Figure 2 shows the grid-like
network architecture of the UMP and its mode of information dissemination. The
grid architecture does provide good and satisfactory services especially in
dynamic institutions [12]. It is also evident that the effectiveness of the
police services has been improved by this network. They have realized some level
of service quality in ICT and its various applications but as described in the
introduction the need for improvement in their services by an alternative
approach to the network system has been researched on. The Police Cloud does
bring in some recommended solutions to the problems experienced by the police
grid cloud and its management to meet their reduced budget.
Figure 3. The Police Cloud
C. How The Police Cloud Works
A cloud service provider as
earlier discussed could provide these services depending on the service level
agreement and cost. The recommended service is the one that allows IAAS and
PAAS platform as a service or a hybrid of these services.
The police cloud will be made up
of computers network (servers and data storage facilities) called Control Node
and other infrastructures. The control node will be the central point of system
administration; monitors traffic, client (Boroughs, management board and
public) needs and ensures a swift communication. A set of protocols called
middleware (software’s) which is defined by the service provider company is
used as an interface to enable communication. It also allows the servers to be
used at full capacity; virtualization and a dynamic operating system. The
company will provide a huge data storage and backup in case of system failure
or attacks. It is also recommended that a 2nd
backup which should be prioritized on the
level of information importance should be located at the user end (The Scotland
Yard).
IAAS and PAAS are of high
importance to the UMP due to its dynamic operations. These services as earlier
described, will enable the officers and staffs develop a virtual machine with
their own specifications according what they require. A platform in which
applications needed by the force for its operations can be run and executed
will be supported. The SAAS can be dynamically used across all the 32 Boroughs,
Op’s Unit, Directorates, Management Board and other Police offices. This can be
optional as most of these software’s used by the police in ICT are
sophisticated and specifically unique for their services.
In terms of deployment model,
these features are specifically defined and designed by the police and
implemented by the service provider company. The various flexible models allow
information
to be shared, monitored and prioritized between departments, local Boroughs,
management levels and external agencies. The public would also have a flexible
and limited access to information which should be defined by the community
cloud model.
D.
Benefits Of Police Cloud
1. Low Complex Systems: figure 3 which
do show the computer servers in digital storage all embedded into the cloud.
Most of the Borough offices will be eased off the burden of constant expansion
of data storage devices as they are all stored in the cloud. This reduces the
physical amount of storage devices as the bureaus just need mostly application
devices to run the cloud services and a low significant amount of backup
storage. The overall complexity of ICT devices attached to OP’s Unit, Frontline
officers (including cars and mobile devices used) and management board offices
will be minimal. The logistics of these ICT infrastructures especially in
mobility and rapid deployment to support operations work will be enhanced.
2. Data Availability and
Reliability: the previous grid-like structure of the UMP network
system describes a 3-way data access route with The Scotland Yard as the
central node. The cloud architecture in which the cloud serves as a hub ensures
a reduced path of 2-way. This dual route with a central cloud that holds all
the data will make information access readily available. The sophisticated
server farms and architecture will improve service reliability. Server
virtualization in the cloud will enhance interoperability among various network
systems. Most of the companies have an acceptable level of integrity with
reliable infrastructure and redundancy in case of general failure. The traffic
will be minimal as the path route will be reduced. Frontline officers, other units
and security agencies will find it easier to retrieve data from any location as
long as they have access to the internet.
3. Reduced
Burden of IT Personnel: the confinement of data, infrastructures and other
cloud ICT systems in the cloud will be in the region of the service provider
company. Part of the agreement which is the management of these resources is
basically done by the company. ICT maintenance, system upgrades and
troubleshooting will be handled by the company. IT support service rendered by
some of the police staff will be significantly reduced to basic computer
components troubleshooting. The services of these staff can be deployed to
other units to enhance operations and effectiveness of the police force. Issues
that may arise within the cloud will be resolved faster as the company image
and integrity is very important to the customers.
4. Improved
Public Relation: A central infrastructure system coupled with electronic
data and files give the UMP a more sociable and interactive way of policing
while increasing their
confidence. The UMP police cloud model will enhance the police community
relations and improve common channel with the public [11]. The public will be
able to conveniently access information anytime regardless of their location.
Real time information on case progression and security awareness update will be
readily available via the internet. Victims and witnesses can be updated
regularly prior to hearings and sittings.
5. Reduced Cost: cloud computing
does bring a general reduction in operational cost of ICT services in any
organization. The previous discussed benefits show a significant decrease in
resources and improvement of services. This paper also looks at the way cost of
the UMP ICT is influenced by the police cloud; some of these positive impacts
are listed below:
• Less amount of money spent on physical ICT infrastructures
across Borough due to cloud hosting.
• The cost of IT personnel training and infrastructure
maintenance is reduced as provider companies are responsible for the overhead
costs.
• Payment is made for only the
amount of usage of applications, software and other infrastructures which will
give room for a better resource utilization and management.
• Significant decrease in cost of procurement, deployment
and ICT upgrades across the Boroughs.
• Decrease in the cost of
production of customized ICT equipment designed for UMP services. Frontline
officers’ equipment; vehicles and mobile devices are less compact.
IV. CONCLUSION
The UMP cloud computing system
shows a significant workload shift from the Scotland Yard, Boroughs and Units
to a centralized and universal way of operation. Local computers and mobile
devices no longer have to do all the heavy lifting when it comes to running
applications as the network of computers and infrastructures that make up the
cloud handles them instead. The idea of embedding data storage within the
police offices is significantly reduced and mobility of frontline officers is
improved. Offices basically needs cloud computing system's interface software
to be installed on computers and devices which can be as simple as a Web
browser. The Police Cloud technology presented in this paper does bring in an
enhanced police service with all the variable characteristics. Operational cost
will significantly be reduced as the areas that take up extra cost have been
handled. A better foundation for expansion and strategic development is set
while bringing the community closer.
V. CHALLENGES, RECOMMENDATION
AND FUTURE WORK
The biggest challenge police
cloud system will be faced with is Security risk [13]. Due to the nature of the
institution this factor is of uttermost importance as their duty also is to
ensure security is maintained while they secure themselves too. Also the
service requires a high level of internet access and connectivity for optimum
operation. These can affect the data rate and overall system performance.
A sophisticated protocol which
should be easy to implement and universal be established. Interoperability
across different service provider companies should be integrated into the Cloud
system to enhance cloud diversity.
Due to the sensitivity of the
security organization in which this research was carried out on, there were
some limitations to certain information which made it difficult to analyse
further. More research could be carried out as to know how this models and
services can be integrated according to their needs.
