Discuss about the Cloud Based Architecture and Systems Integration.
The report is prepared for the IT transformation at Dell and with the implementation of system integration engineering. The system integration is used for breaking the system into manageable components and cooperating with the other system such that the link between the systems is identified. There are different technologies used in the system integration such as computer networking, integration of the enterprise application, management of the business process, etc. A conceptual architecture model of the current framework of the organization is created for introducing new ideas and creating guiding principles. In the conceptual architecture the system context and the architectural overview diagram is created in the report.
The main goals of the project is the transformation of information technology in Dell for supporting the expansion of the company. Current information system of the organization needs to be transformed for management of the supply chain and operating as a single enterprise. The conceptual architecture is identify the current information system blocks and find its interaction for transition into a conceptual model.
The system context diagram is used for identification of the boundaries between the system and its environment and demonstrating the entities that interacts with each other. The diagram is able to show a high level view of the current system and it have some similarities with the block diagram. The diagram shows the inputs and the outputs from the external factors and it is used in a project at the early stage for the identification of the scope of the project. It helps in identification of the items included in the requirement for the development of the project.
The architecture overview diagram is created for the company for getting a fine grain view of the high level architecture and identification of the overall elements of Dell. A base terminology needs to be established and it can be used as a reference between the other elements of the information system architecture. The current reference architecture of Dell for the transformation of the IT is needed to be evaluated for reducing the errors in the organization. The data domains and the integration of the information is important for the improvement of the functionality of the system. The connectivity and the functionality between the services and the communication channels used for connecting the services with each other is identified for the creation of the architecture overview diagram.
The logical architecture diagram is created by understanding the technical functionality that is required for the transformation of the information system. The legal issues may arise during the transformation different countries have different standards and thus for the transformation of the information system the universal standards needs to be followed and different service such as cloud hosting services can be implemented for the management of the data and integrating with the new information system for communicating using the connectivity and interoperability services. The nonfunctional services such as the availability, retention, security, quality of service and the capacity are related with each other and demonstrated in the logical architecture model. The different services such as the business process orchestration, collaboration, privacy and security of the information are required to be managed for clearing the relationship between the conceptual architecture and the logical architecture view diagrams created for the transformation of IT in Dell.
The component model is used of demonstration of the relationship between the logical models. The component model is created by grouping a specific set of capabilities that performs a specific functionality. The model is divided into three parts such as component relationship diagram, component description and component interaction diagram.
It is used for the demonstration of the interfaces and their relationship with the components. The elements from the logical model is used as the components and the components are used for populating the diagram to provide the logical function. The components are used as a part of the component model.
There are different types of components used for the development of the component model and it is describes in terms of the service, interfaces, functional and the nonfunctional requirement. Depending on the project needs the description of the project includes a unique ID that is used for the identification, name, description at a high level, description of the service and the interfaces used for establishing the connection between the different processes. For meeting the It transformation at Dell the component collaboration Hub and the information co production hub is different from the enterprise information architecture reference architecture model and described below.
High level Description – It is related with the requirement for the IT transformation at Dell for creating an interaction between the constituents and the government bodies regarding the government policy and the legal issues that should be mitigated for expansion of the current system. The collaboration hub does not helps to provide different collaboration service but it is used for discussing and interacting with the different components. It is used as an interaction gateway at Dell and allowing the organization to control and secure the different components. The constituents are connected to the collaboration service via the collaboration hub for exchanging the information between the different branches of Dell for integration of the data and support the expansion of the information system. For the implementation of the new technology the security of the information system should be considered and the access of the directories must be approved via the means of authorization and authentication mechanism for increasing the reliability of the collaboration service.
Interfaces – At the presentation end the continuous streaming and update of the collaboration service is important. The presentation service can be presented with multiple collaboration such as web portal, dashboard, mobile application web application, etc. as an external presentation. For the internal interface the portals is connected with multiple collaboration services and instances using the connection Hub that is provided by the collaboration services.
High level description – The component information co production hub is interrelated with the requirement for the transformation of the IT in Dell and is used for the presentation of the constituents as a single organization and use a single interface for the management and enabling the constituents of the organization. The information co production hub is used view the consequent request for viewing different services that are interrelated with each other. The information co production hub allows the administrator to view the request of different services and identification of the relation between the services. For example id Dell wants to view the tax information the portals of the company and the interrelated company are integrated to form a virtual portal and return the information on the same generic portal. The presentation service is the main platform that is used for creating a reliable connection and authenticate the constituents as a single on to access all the authorized portals required for returning the data.
Interfaces – Multiple portals are needed to be accessed and presented simultaneously for the presentation of the constituents and providing the different service required for the IT transformation of the organization and expanding the business. The internal gateway or a bridge is required to be configured for creation of a bridge for accessing the data residing at different database of the branches and the other portals of the companies associated with the current business process of thee organization.
It is used for representing the dynamic interaction between the different components that are required for meeting the current scenario of the organization. It is used as a high level interaction for the verification of the components and the configuration of the current business process. The IT transformation needs to access the co-production Hub and firstly administrator should be authenticated for accessing the resources and information of the organization. Appropriate portals are accessed and the data is gathers for creating a backup and integrate it ij the new information system for the transformation of the current information technology of the organization.
The operational model is created form the component model and distributing them to the nodes connected in different geographical locations. The model depicts the flow of the data and the connection. Each of the nodes connected in different location consists of different components as are identified as the deployment units. The component model can be broken down into different functional and nonfunctional operational model.
There are many template available that can be used for the development of the logical operational model. The model is created for increasing the availability of the unstructured data that are gathered from different sources during the transformation of the information technology of Dell. The continuous availability and redundancy of the data is important for reducing the errors in the transformation process and maintain the continuity in the current business process for mitigating all the risk associated with the transformation of the current IT. It can act as the subsystem for the transformation of the current IT at Dell and relating the functional and the non-functional operational models together.
Conclusion
From the above report it can be concluded that with the development of the different enterprise architecture model the current information system at Dell can be easily identified. For transforming the current information system the standards that are needed to be followed and the capabilities of the system can be identified by designing a building block diagram and different architecture overview diagrams The architectural overview diagram provides the non-technical views of the organization for the development of the enterprise information system. The diagram are used for the translation of the concepts into different information system and broken done into different components for describing the log that is tested using the component models. For setting out all the components the operation model can be broken down depending on the location of the nodes connected in the network.
