Online Spatial Delivery System

Question: Write an essay onOnline Spatial Delivery System. Answer: Introduction OSDS is based on the PaaS model of cloud computing. Platform as a Service (PaaS) is a model that provides the platform for the development of an application and all the relevant environmental requirements as well ("What is PaaS?", 2016). The six components that play an important role in the migration of OSDS to a cloud provider are Remote Administration followed by Resource Management and SLA Management. The other three in the list that play a significant role are Application Resilience, Data backup and storage along with the Disaster Recovery. Remote Administration It is a process that allows the controlling and other tasks doable from a location that is remote in nature (cbigconsulting.com, 2016). There are a few shortcomings associated with this component and are described further. There are a number of tools that do not scale properly and that emerges as an issue for the remote administrator. At the computer system level and at the mobile devices level, there are multiple operating systems that are being used by the organizations with Android, Windows and iOS top in the list. These operating systems have varied speeds and characteristics which distinguish them from each other. However, this becomes a problem for remote administration as multi-platform support becomes a tedious task. There are also issues associated with the security measures such as cryptography, authentication measures and the steps taken to control the access (sans.org, 2016). Resource Management Resources are the asset of any organization and there are many resources capable of multiple skills associated with the organization. Some of the resources such as business owner, project manager, database administrator, operations head, networking head and several teams such as those belong to the design, development, testing, networking, support and maintenance departments play a significant role. It is of utmost importance to manage these resources and before the project begines, there needs to be answers in place for the following questions. Does OSDS has a resource tagging strategy or needs to be developed? What is the involvenet of internal structure management? What is the policy and procedure that is followed in the allocation of resources? What happens with the resources if the project is completed before the deadline or gets delayed? What is the position of metadata in OSDS? (s3.amazonaws.com, 2016) There are a number of advantages for resource management as: It would enable a central file server and repository for the resources and their details. All of the information can then be handled from one location ("Project Resource Management Benefits | Innotas", 2016) Assessment of the resource skills would become easy Complete transparency between the workers and the managers Attendence management, leave policy and change management would become handy (Singh, 2013) A strong connect and bridge would be formed between the employee, employer and the set goals of the company ("Human Resource Management (HRM) - duties, benefits", 2016). Increase in efficiency and productivity by a good margin. SLA Management SLA is a contract or a written agreement that defines the services that have been agreed upon between the user of the service and the provider of the service. DSI and cloud provider are the respective parties that would be involved in OSDS as user and provider. SLA is defined and designed at three different levels. The one that is of prime concern in case of OSDS is at the service level (Bose et al., 2011). The following factors would be of prime importance in OSDS: The details of the services such as features and budget associated with the services that have been finalized between DSI and cloud provider Resource allocation process and the roles that have been assigned to each member from low to top management Role of internal partners in the project and services A flow chart depicting the processes in a high level Indicators that define the status of performance (mitsm.de, 2016) Application Resilience Like every other application and project, OSDS also has a set of requirements that are of higher priority than the rest. Such requirements are termed as High Availability (HA) requirements that require well planning and immediate support for execution. The best practice to follow in this case is the development of business strategy that targets the following points apart from the rest: An application that is sure to provide the services at all times in a reliable manner Downtime of the services is minimal Best practices are used in every phase Ample data storage option Cloud architecture Data Storage and Backup Big Data tools and databases such as NoSQL can be used for efficienct storage and backup of the information associated with OSDS. NoSQL is the datbase that can store and analyze the data without any complications. Easy visualizations, rich reporting and flexible modes are the added features of the database. It can also aid in the predictive analysis of data (Pentaho, 2016). Here are some of the examples of NoSQL databases: AmazonSimpleDB The task of dB admin becomes easier with this one and it belongs to the non-relational category (Goes, J. 2016). Terrastore Consistency, scalability and superb performance are the features that come with this one. It offers indexing features too (Big Data Made Simple - One source. Many perspectives., 2014). MongoDB It is an open source agile database that offers scalability, supreme performance and high availability. Elasticsearch RESTful web services can be used with the help of this one as it has the ability to support the same. Disaster Recovery There are a number of risks that are associated with the cloud services and the measures need to be adapted such that the impact of harm in occurrence of such an event is minimum and the services are brough back to normal in a quick turnaround time. These are the measures that should be adopted to avoid the risks at the first place and recover from the same. Preventative These are the primary points of security that must be present in any organization and its architecture such as use of anti-virus, set up of firewalls and physical security measures such as guards at entry points and use if an identity check. Reactive These come in the picture when the event has already taken place. Detective Measures such as intrusion detection and motion detection fall in this category of countermeasures Administrative There are always a defined policy or a set of guidelines that is associated in the business strategy. These measures make sure that all the processes adhere to the same. Disaster Recovery (DR) in cloud computing is the method to have proper backup and recovery strategy in place which focuses upon management of the copies of data on the cloud ("What is cloud disaster recovery (cloud DR)? - Definition from WhatIs.com", 2016). DR would allow the recovery process to be enabled in multiple locations (Kiblin, 2011). There are a number of strategies that have been developed in order to have a correct DR procedure (aws.amazon.com, 2016). Cloud for disaster recovery is a viable option for DSI both from the financial perspective and from the control perspective as well (Dix, 2016). Conclusions Opportunities and Risks Cloud suffers from certain potential and probable risks as well that mainly revolve around data protection and information security. These risks include loss of data, accessing of the data by an unauthorized user, denial of services, attack of malicious software, spoofing, phishing and inadequate due diligence. Such risks possess a threat to the confidentiality, integrity and authneticty of the information, Use of authorizations measures along with proper access controls are mandatory to protect the data belonging to OSDS. The data associated is private and confidential in nature and the landing of the same in unauthorized hands could be extremely adverse for DSI. ("Risks of cloud computing | Queensland Government", 2016). The six components that have been discussed in the migration of OSDS to the PaaS model of cloud computing reolve around the storage of data and the use of best practices in the management of SLA and resources. Remote Administration is one area that suffers from certain major drawbacks associated with the support and scalability. It is recommended to develop a business strategy for every entity and then proceed according to the same. It would not only help in achieving the results but would also provide fault tolerace, availability and reliability of the services.
