Introduction
In last few years, companies have been striving hard to maximize efficiency of their ICT infrastructure in order to have high returns on Investment. As a result of this, new Information Systems applications have been developed to enhance the working of the companies by providing them a platform to re-design their enterprise environment. This will create a dynamic and agile enterprise known as virtual enterprise around the interruptions in market. Today’s world is moving towards a global economy on the basis of  e-commerce which is demanding a platform that has web-based and flexible integrated infrastructure known as Virtual Enterprise Resource Planning (VERP) and Federated ERP. These infrastructures are merged with Service Oriented Architecture. To combat with the rising competition, companies have started setting up the ES solutions like cloud computing. This solution aims at providing solutions to the complication issues arise in the traditional on-premise ES.
The current industry literature does not have a formal or a common definition of Cloud ES. This report aims at creating definition and perceptions from Academia and cloud industry. In order to minimize gap between them, this report will intend at contributing to the Cloud ES literature development. This will be done by providing a common platform for defining cloud ES. There are various ambiguous definitions of cloud ES which can create obstacles in defining theories, measurements and models of cloud ES. Hence, this report will start with conceptualizing the cloud ES and then proceed further with the detailed explanation of different types of service model of ES and various different deployment methods. This methods are presented to provide deep understanding of the market offerings. The research will conclude with the advantages and challenges of cloud ES which will allow its clients to prepare their business before going for its implementation in their needs.
RESEARCH METHOD
The review of emerging trend can be done by conducting its systematic review and it includes search process, filter process and classification process. According to the (Levy ), the systematic review has three sequential activities i.e. input, process and output. Along with this (), extensive study of relevant papers can also be conducted to investigate the areas and then identify the patterns in those papers. This will represent the state of art of the problem domain. On the basis of this research method, this research aims at development of conceptualization of cloud ES and it is performed through following steps: First, search on the literature of cloud ES is conducted from famous journals on Information system, conference proceedings and periodical databases. Then relevant articles are selected using keywords such as “Cloud ES”, “Software as a Service” etc.  This resulted in selecting around 45 articles to work upon and get familiar with the cloud ES.
Literature review
The IT systems have undergone a major structural change in the last few years where its internal resources and infrastructure is being standardized and used in the form of cloud service through Internet. This has led to the emergence of phenomenon known as cloud computing. It is a witness which has seen the invention, development and scaling in IT services. In this change, organizations pay only for the services which they use. As a result of which, this study will create literature review on basis of associated domains such as Cloud ED conceptualization, pros and cons of adoption of cloud ES and Cloud ES/SMEs.
Current ES Landscape
The current ES system is an internal information system which is unable to support and face the challenges of e-business and exhaustive requirements of data. As a result of this, ERPII - a new enhanced enterprise system was adopted which allows interaction between the inter-enterprise processes through value chain. It needs the involving companies to use benefits of ES by combining it with the new types of business tools. This combination will benefit both the upstream and downstream chains in order to enhance the capabilities of ES. Apart from this, (Tarantilis) defines a new web-based enterprise IS which is a modular, separable and pluggable system. In the similar manner, cloud computing has revolutionized the ways through which IT service are invented, deployed, updated, maintained and updated. The presence of cloud computing  allows easier deployment of ES methods.
Cloud ES Conceptualisation
All information systems and technologies are mature and have already customized in the form of new emerging technologies. The cloud computing concept is new and being treated as an emerging platform.
Features of Cloud Technology
Following are key features of cloud technology
· On-Demand Self Service - With the help of this features, a customer can take advantage of any computing resource - storage space, application program etc. from the service provider without any intervention by a human.
· Broad Network Access - This feature allows users to access resources from any location and any underlying device through internet.
· Resource Pooling - This resource allows provider to assemble the resources in a service. Even if these resources are spread over a vast area across different data centres. These resources are used by multiple customers. These resources are assigned to the users on the basis of their demand.
· Rapid Elasticity - The customers are free to request more resources in times of high demand and may even release the extra resource in low demand times. The customer will pay only for the resources used.
· Measuring Service - Cloud computing are adaptable in nature,
· Cloud computing systems are adaptive systems. They automatically balance loads and optimize the use of resources. A user is permitted to monitor and control resource usage, thereby providing transparency in bills.
Cloud Delivery Models
There are three different predominant methods of delivery of cloud computing services. The IaaS based model is...
