ERP Systems in the Cloud
Introduction
Enterprise Resource Planning (ERP) is a business process management system that provides
an organization with the ability to integrate its business functions and automate the business
operations. The key operations that are carried out in a business enterprise, such as
manufacturing, production, financial, human resources, customer relations, supplier relations,
etc. are managed with the aid of ERP systems. The implementation of an ERP system in an
organization provides it with several benefits, such as increased collaboration, enhanced
accuracy of operations, better scalability, better security of the data sets, and a lot more.
The implementation of ERP systems can be done using a variety of different methods. The
use of cloud is one of the mechanisms that can be used for the implementation of ERP
systems. There are various cloud platforms and models that can be used for this purpose. For
instance, on premise cloud can be used for implementing ERP systems. Hosted ERP systems
and cloud ERP systems can also be used for the implementation.
Statement of Purpose
The purpose of the report is to bring out the involvement of cloud in the implementation of
the ERP systems by discussing various cloud platforms that may be used for implementation
purpose.
Report Structure
The structure of the report includes three major sections as introduction, ERP Systems in the
Cloud and Conclusion. The various cloud platforms that can be used with the ERP systems
have been explained in the second section along with the benefits, drawbacks, features, and
case studies of each. A brief conclusion of the report is presented at the end.
ERP Systems in the Cloud
On-Premise System
Features & Benefits
On-Premise ERP refers to the approach in which a company purchases the license of specific
ERP software and then installs it in their organization. The sourcing of the system is done in-
house and its maintenance is also done at the physical location of the organization. There are
various benefits that are offered by on premise ERP.

ERP Systems in the Cloud
 Data control: The confidential and private data sets of the enterprise are handled by
the ERP systems. An organization may include the information sets, such as
demographic details of the employees and the customers, details of the suppliers,
social security numbers, financial information, and a lot more. With the
implementation of on premise ERP, there is complete control provided to the
organization. The security controls and physical access controls are also applied by
the organization that reduces the probability of security risks and attacks. The other
mechanisms, such as use of hosted or cloud ERP leads to the emergence of increased
number of security risks on the data sets (Mezghani, 2017).
 Less vendor dependency: In the case of cloud-based ERP systems, a majority of the
decisions regarding the technical infrastructure and architecture of the system is taken
by the vendor. In case the vendor moves out of the business, the ERP users are left
confused and the maintenance of these systems cannot be effectively carries out.
However, in the case of on premise ERP systems, the dependency on the vendors is
removed. The system aspects can be changed or modified as a result.
 Limit on-going costs: The initial cost that is associated with the on premise ERP is
higher; however, the overall cost of ownership comes down with the installation of on
premise ERP systems. The only costs that are associated with on premise cloud
energy costs and maintenance costs.
 Foundation for future hybrid cloud expansion: It is possible to integrate the public
cloud applications and services with the on premise cloud. The compromise on the
critical issues, such as data control and security are also not compromised during the
expansion process (Boillat and Legner, 2013).
 Easier customization: There are various applications and services that are pre-
installed in the enterprises. The installation and implementation of on premise cloud
eliminates the need to remove such applications and an opportunity is provided to use
the customization options integrated with the ERP workflow.
Drawbacks
There are certain drawbacks that are associated with the traditional ERP systems. Some of
these disadvantages are as listed below.
 There is an upfront cost that is associated with the on premise ERP systems. This cost
is very high and is paid in the initial phase. The small and medium-sized firms may
not be able to bear this cost due to budget constraints.

ERP Systems in the Cloud
 Apart from the initial costs, there are also a lot many indirect costs that are associated
with the ERP systems. These include the cost of resources, cost of maintenance, and
likewise.
 There is complete control of the traditional ERP systems on the internal employees of
the organization. In case of the unskilled employees, the ERP system may fail to
provide the organization with the due benefits.
Case Studies
There have been several successful case studies that have been recorded with the
implementation of the traditional ERP systems.
One such case study is of The Oman Telecommunication Company (Omantel). The
organization made use of the on premise ERP system to achieve the benefits as higher
accuracy of the operations, faster processing, and enhanced security. The confidential and
private data sets of the enterprise were handled by the ERP systems (Maguire, Ojiako and
Said, 2010). These included the contact information of the clients, employee data, networking
information, vendor details, etc. With the implementation of on premise ERP, there was
complete control provided to Omantel. The security controls and physical access controls
were also applied by the organization that reduced the probability of security risks and
attacks. The other mechanisms, such as use of hosted or cloud ERP could have led to the
emergence of increased number of security risks on the data sets. However, Omantel could
protect its data sets with the implementation of traditional ERP.
Mesfine Industrial Engineering (MIE) Pvt. Ltd. is a company that is based out of Ethiopia
and works in the areas of metal construction and electromechanical engineering. The
company implemented ERP systems in its enterprises and could gain several benefits out of
the same. The legacy systems that were earlier being used in the company were not sufficient
and had issues with the communication between the customers and the suppliers. Also, these
systems were not agile enough to meet the changing needs of the organization. The company
therefore decided to implement ERP systems in its architecture and decided to follow a
phased approach for the purpose of implementation. There were seven phases that were
involved and the project kick started on 17th March 2008 and ended on 20th October 2008
(Boltena and Gomez, 2012). There were various applications and services that were pre-
installed in the enterprises. The installation and implementation of on premise cloud

eliminated the need to remove the necessary applications and an opportunity was provided to
use the customization options integrated with the ERP workflow.
Hosted ERP System
Features & Benefits
The second category of the ERP systems that is commonly seen is the hosted ERP system. In
this case, an organization purchases the license for the ERP system and then deploys the
system on a third-party infrastructure in the cloud. This mechanism is also referred as
Infrastructure as a Service (IaaS) cloud model.
There are various benefits that are provided to the organization with the use of hosted ERP
systems.
 The primary benefit that is offered with the use of hosted ERP systems to the
organization is the lower infrastructure costs. The infrastructure is setup and
maintained by the cloud vendor and the organization is exempted from making any
alterations to the infrastructure. The enterprises are required to pay only for the
capacities and functionalities that they will be utilizing and overall costs come down
as an outcome.
 The requirements of an organization are dynamic in nature. There may be changes in
the enterprises requirements that may be observed due to change in technology,
modifications in the market trends, customer preferences, and likewise. Hosted ERP
systems are scalable and flexible in nature. They can be easily scaled up or down to
meet the needs of the enterprises and the changes can also be made without much
effort.
 Disaster recovery infrastructure is provided by the hosted ERP systems and in the
case of a security risk or an attack, the accountability of the attack is taken up by the
vendor. The organizations are not required to bother about the downtime and the
damage that may result in the occurrence of a security attack.
 Organizations can keep their focus on the business growth and are not required to be
bothered about the technology decisions. These decisions are taken by the vendor.
The installation of the updates is also done by the vendors along with management of
the patches.

ERP Systems in the Cloud
Drawbacks
There are also a few drawbacks that are associated with the use of Hosted ERP systems.
 There is involvement of cloud in the hosted ERP systems. The cloud platforms are
exposed to various forms of security risks and attacks. The ERP data may also be
exposed to the security risks and attacks. Some of the risks that may occur include
malware attacks, data breaches, data loss, data leakage, and denial of service attacks,
man in the middle attacks, eavesdropping attacks, and many more. The occurrence of
these security risks and attacks on the ERP systems may lead to other negative
implications.
1. The clients and the end-users may file legal suite against the organization and
the organization may be required to deal with the legal obligations and
punishments.
2. The satisfaction and engagement levels of the customers will come down.
3. The reputation of the organization and the vendor will be deteriorated in the
market which may have a negative impact on the sales and profits.
 In these ERP systems, the responsibility of managing the backups of the data sets will
be on the organization itself. The vendor will not carry out any of the data backup
activities. The organization may not be able to successfully carry out the backup
activities which may result in data loss.
 There will be use of virtual machines in the hosted ERP systems. Customer will be
responsible for the management of these virtual machines.
Case Studies
Ray Allen Manufacturing is an organization that was set up in the year 1948. The company is
one of the leading manufacturers of canine equipment for military and police departments.
The legacy systems of the company are AS400 and there were issues that were being
experienced by the business executives in the legacy systems. The business executives and
management committee decided to implement hosted ERP solutions in the organization for
enhanced flexibility and integration of the operations (Cdn, 2017). The company made use of
hosted ERP systems and could gain benefits, such as increased collaboration, enhanced
accuracy of operations, better scalability, better security of the data sets, and a lot more. The
requirements of the organization are dynamic in nature. There were changes in the enterprises
requirements that were observed due to change in technology, modifications in the market
trends, customer preferences, and likewise. Hosted ERP systems are scalable and flexible in

nature. They can be easily scaled up or down to meet the needs of the enterprises and the
changes can also be made without much effort. The use of hosted ERP systems allowed the
organization to make changes in its requirements and business operations.
Seaport Capital is another organization that implemented hosted ERP systems in its
organization. The main benefit that was offered with the use of hosted ERP systems to the
organization was the lower infrastructure costs. The infrastructure was setup and maintained
by the cloud vendor and the organization was exempted from making any alterations to the
infrastructure (Cdn, 2016). The enterprise was required to pay only for the capacities and
functionalities that they will be utilizing and overall costs came down as an outcome.
Cloud ERP System
Features & Benefits
It is the ERP system which completely functions in a cloud environment. The company pays
for the subscription of the ERP cloud to the vendor and shares the same with other firms. It is
also referred as Software-as-a-Service.
There are various benefits that are provided by the cloud ERP systems to the organizations
and the end-users.
 The cloud ERP system eliminates the requirement to pay extra for the software
licenses. There is a subscription fee that is attached with the desired period of usage
which may be paid monthly, quarterly, half-yearly, or annually as per the wish of the
organization. The fee that is associated with these systems is usually affordable which
can be handled by the small and medium scale organizations as well. The additional
infrastructural costs, such as that of data servers and hardware are brought down
(Elragal and El Kommos, 2013).
 It is required to upgrade the cloud ERP systems at regular intervals. The cloud
vendors in the market release the updates and installs & manages these updates for the
clients. The upgrade process is done at the time of minimal traffic on the system
which does not bother the usual functioning for the organization. The system is kept
up to date at all time and there is no cost that is associated with these updates.
 The downtime associated with the cloud ERP systems is very low. Thus, the
organizations get the ability to make the complete usage of the application as per their
requirement.

systems are scalable and flexible in nature. They can be easily scaled up or down to
meet the needs of the enterprises and the changes can also be made without much
effort.
 There are several damage and disaster recovery plans and processes integrated with
cloud ERP systems. Backing up of the data sets is done by the cloud vendor to make
sure that the systems run at all times and the data sets are also kept protected.
 There is an option of customization that is offered along with the cloud-based ERP
systems. This allows the organizations to target and meet their current as well as the
future needs.
 There are several cloud vendors to choose from. This allows the organization to carry
out the market study and select the cloud vendor that may fit the best as per their
needs and requirements.
Drawbacks
There are also a few drawbacks that are associated with the use of cloud ERP systems.
 There is involvement of cloud in these ERP systems. The cloud platforms are exposed
to various forms of security risks and attacks. The ERP data may also be exposed to
the security risks and attacks. Some of the risks that may occur include malware
attacks, data breaches, data loss, data leakage, and denial of service attacks, man in
the middle attacks, eavesdropping attacks, and many more. The occurrence of these
security risks and attacks on the ERP systems may lead to other negative implications.
The clients and the end-users may file legal suite against the organization and the
organization may be required to deal with the legal obligations and punishments. The
satisfaction and engagement levels of the customers will come down. The reputation
of the organization and the vendor will be deteriorated in the market which may have
a negative impact on the sales and profits (Abd Elmonem, Nasr and Geith, 2016).
 The overall costs associated with cloud ERP systems are low. However, there are
other costs that are related with Cloud ERP. One such cost is the cost of ownership.
 There may be heavy customizations that may be needed by the organizations without
disturbing their legacy systems. Such a requirement may not be met by the cloud ERP
systems.

SARMED is one of the Greek companies that were founded in the year 1955. The company
deals in the area of logistics and supply chain services. The company implemented Nubis
Cloud ERP system in its organization. The company achieved various benefits with the
implementation of the ERP system. The cloud vendor, Nubis Cloud ERP releases the updates
and installs & manages these updates for SARMED. The upgrade process is done at the time
of minimal traffic on the system which does not bother the usual functioning for the
organization. The system is kept up to date at all time and there is no cost that is associated
with these updates (Nubis, 2018). There are several damage and disaster recovery plans and
processes integrated with cloud ERP systems. Backing up of the data sets is done by the
cloud vendor to make sure that the systems run at all times and the data sets are also kept
protected.
