Question:

Discuss about the Virtualization and Cloud Computing for Reliability and Maintainability Symposium.

 

Answer:

Introduction
 
The report that is been discussed here explained about different aspects of cloud computing related to Department of spatial information such as service level agreement between the two parties or companies in which one is a service provider, and another one is the client or customer. Detailed information and assessment are required for SLA management and technical evaluation. The report gives us an overview of what risk is there and what are the major opportunities that DSI can observe and identify them. Department of spatial information has already selected the vendor, and a detail report is presented to understand the SLA management and assessments requirements. The document provides a detail information about the backup and recovery plan for Online Spatial Delivery System (OSDS).
 
Requirements for SLA and Resource Management and Remote Administration
 
Resource management:
 
This refers to a method or process which manages the physical resources and the resources such as network bandwidth, CPU cores, and disk space. It is an efficient and active use of the resources and evaluating the price of the resource are the significant aspect that involves resource management (Kaewpuang et al., 2013). This physical components or resources should be shared and sliced among the virtual system running likely with the workload.
 
Elements of Resource Management

It is a control panel, or we can say a portal where the system administrator can access it remotely from anywhere in this globe. The system or computer within the same network can transfer the information or data by using a wireless or Wi-Fi connectivity. The Wi-Fi technology is very basic and standard nowadays in every organization. Moreover, it is the standard requirement for hardware resources management. The Department of spatial information needs to create workstations for themselves.  It is used by only one individual at a single period, but as the systems are connected internally, it can be accessed by some users at the same time. The workstation will be managing the utility of technical and scientific applications (Jhawar et al., 2012).

 

SLA management:

Department of spatial information has decided that they will include the Hybrid cloud based system solution in their organization and a proper document, or paperwork is done which is known as SLA (Service level agreement). The report states that what kind of services and what extra benefits the service provider is going to be provided to the Department of spatial information. The report also clearly explains that what are the fines and penalties that will be imposed on the service provider if they fail to deliver the promised service that is mentioned in the service level agreement and that penalty will be paid to the DSI without any more queries. It is an assurance that the service provider will provide DSI a quality product and service as mentioned in the SLA.

Service level management

The Service level agreement is managed by SLA management, and the DSI needs to present well in front of the vendor so that the supplier can provide a better service as the DSI requirement. The implementation of the agreed solution by the Department of spatial information will add an extra protective layer to their data hosting services and existing systems. This SLA contains all this information in much more details to make the vendor understand the DSI requirements.

Remote Administration:

The resource management, billing management, and service level agreement management system for user interface and tools and infrastructure is provided by the remote administration. It is a process or a method. On remote administrative system, the Department of spatial information can have the control over other administrative systems as mentioned in the below diagram figure 2.  The software that is used for remote accessing is very common and popular because if the user is not present in front of the computer they can access the computer from their current location.

Remote Administration System

It provides several API support and tools by which the vendor can modify and develop many portals for their customers to provide a very user friend experience regarding cloud computing.   They provide that extra power to the user to access the data from their present location. It is used to shut down and reboots another desktop over a network. With the help of the remote administration, Department of spatial information can control their existing administrative applications and tools. It helps in installing software for other system and other system registry settings. Department of spatial information needs to look that the kind of IT resources and cloud services which is required to be integrated into the system through a self-service portal, that will help them to implement the facilities of remote administration.  DSI needs to their vendor first to incorporate the remote administration system in their organization by creating an online portal by which they can customize things as they require.

Describing Resilience, Disaster Recovery, and Data Backup

 


Disaster Recovery and Data Backup

The theory of disaster recovery deals with the process of recovering the data that has been lost due to technical errors. The disaster recovery using cloud system is a new approach to the management of data and information system. The whole procedure of data recovery process is divided into five stages.

Different stages of data recovery process

(Source: Alhazmi & Malaiya, 2013, pp. 4)

Department of spatial information needs to choose the right vendor to make sure that they have the right data recovery and backup plans. The organization has to ensure that the provide techniques and tools for backup and disaster recovery are well tested. This is to be done to avoid any future consequences between the service provider and DSI.  They are implemented to deal with the issues that are either human-made or natural disasters. To decrease the points, there are some key steps that need to be considered.

Reducing the delay of risk:

DSI has to choose the right vendor who has a well-tested recovery plan so that they can protect and recover all the data at the right time and which will decrease the risk.

 


Securing the data:

The data can be retrieved later by using various disaster recovery process, but the main issues are to ensure that data in DSI where the data's are shared in the public and government domains.

Backing up the data at the right time:

The data needs to be ed supported at the right time which means that the natural disaster can occur at any point in time, and the best way is to recover the data from the incident takes place which will inevitably reduce the risk.

Resilience:

It refers to the ability of the complete data center, server, storage system and network.  It is used to quickly recover the data. Department of spatial information should concentrate on resilience process or methods during the integration of Hybrid cloud based solution infrastructure in their present OSDS model. It works when there is a failure of equipment and if there is no power or other interruptions. Through other internal system and components or by datacenter enabling the resilience is obtained. The resiliency is proposed when the planning of the project is presented, and it creates the connection between the data center for disaster recovery and emergency plan. It reacts to all the issues that are related to the web application that is built or developed internally and can provide us the product and best solution for these matters. It is growing in much better speed, and it has also become the major part of the organizations.  The resilience application can be divided into multiple layers that are the server, storage and infrastructure layers (Diez & Silva, 2014).

 


Service Level Agreement Assessment with Erl’s SLA Guidelines

The service level agreement refers to a verbal communication between Department of spatial information and the service provider. The company is looking to implement the Hybrid cloud based solution model that is been done through IaaS method. There are some important aspects that needs to be addressed so that it can be helpful for future implementation enhancement of cloud computing. The service level agreement guideline has to be proper and perfect and that needs to be clear as well so that both service provider and the client can understand it. For example, if there is any new terminology that is been created then it has to be included in the SLA so that both the parties may not get confused. In a cloud based solution, the client uses the API for the End User interface, and the client will use various technologies such as communication with another implementation service and website services for gathering all the information. In SLA, the guidelines which are defined need to be kept updated. It is important to keep the guidelines up to date, and it's the responsibility of the vendor before presenting an agreement to the client. With the implementation of the cloud computing in many organizations and firms, it has been a commonly known by everyone.  As it provides the ease to access the data from anywhere in the same cloud network. SLA has helped the service provider in increasing their quality of service for managing their infrastructure and nonviolent methodology of business management. The authority of the access to the resources with the help of different cloud services can be attained by the implementation of SLA (Chou, 2015).

Conclusion

Cloud Storage and Computing is the most advanced type of data analysis and storage. The report shows the analysis of the different measures that Department of Spatial Information needs to follow for implementing the Cloud based storage structure in its management system. The Recovery supervision, SLA management and wireless administration of the organization DSI are crucial for the implementation of the improved management system. The Recovery supervision, SLA management and wireless administration of the organization DSI are crucial for the implementation of the improved management system. The report explains the reasons for the necessity of the wireless system and SLA management in DSI organization. The cloud based storage structure requires data backup and recovery system, and the structure should be implemented correctly. DSI cloud computing system is benefitted by the proper risk management.
