Question:

Discuss about the Management Backup and DR.

Answer:

Introduction

This report discusses the importance of remote administration, resource management and service level agreement (SLA) management. The report includes operational checklists to assess the results.

It also includes brief discussion on how will one consider application resilience, backup and retrieval for chosen service provider with respect to payroll services and information exchange. It further includes assessment of SLA for the chosen service provider using Erl’s SLA guidelines. Moreover it highlights the major opportunities and risks that are identified during the assessment.

1. Requirement for Remote Administration

Internet Connection: Any computer that is connected to the internet through Local Area Network (LAN), or IP/TCP can be remotely administered. For non-mischievous organization, the client should establish or permit service software in the system of the host for viewing, after that the client will be able to access to the system of the host from different system through the software installed. Generally, both the administrator and the host should be connected through the online network and the IP address of system of host should be known (Subramanya & Iyengar, 2016).

Administrative Tools: An administrative tool is required to be installed by the service provider in the computer of the administrator. When the client connects with the host’s system, a pop-up window of the host appears on the computer of the client, the client could control the activities of the host like the host is physically present in front of the client.

Resource Management

Admission Control: It requires controlling the assignments taken by the system and it also requires having the knowledge of the overall condition of the system.

Capacity Allocation: The administrator is required to allocate tasks to different nodes of the system optimally to ensure smooth functioning of the system (Manvi & Shyam, 2014).

Energy Efficiency: Placing some of the servers in reserve mode and using low power central processing units to ensure efficient consumption of energy.

Quality of Service: Ensuring a standard level of the service provided to the users that is often in service level agreement (Rittinghouse & Ransome, 2016).

Service Level Agreement (SLA) Management

Type of Service: It states the kind of service and any supplementary details of kind of service to be offered. In the case of IP network connection, the service details will illustrate functions such as maintenance of network tools, connection bandwidth being offered, operations (Wu & Buyya, 2012).

Service’s Preferred Performance Level: A dependable service would be the one that suffers least disturbances in a particular period and is available almost all the time. Service with high reliability and good responsiveness will perform at the preferred level.

Report Issues: This component will mention the communication details to state the problem and the sequence that problem needs to be reported.

Issue Resolution Time Period: The agreement will also include the time period within which the issues will be resolved. It includes the time taken by the service provider to investigate the issue and fix it.

Process Monitoring: This component explains the process of supervising and monitoring the performance of the service level. It comprises of collecting various kind of statistics, the frequency of collection of such statistics and how such statistics would be accessible to the users (Carvalho et al,. 2012).

Reverberation for Service Provider: In case a service provider is unable to meet the preferred performance level as specified in the service level agreement, then the service provider is ought to face the consequences.

2. Application Resilience

Every application has certain high availability (HA) obligations and features. AWS offers numerous infrastructure construction blocks to facilitate the organization in achieving its requisitions in cost effective manner. At higher level, competent HA strategy will comprise instance repetition, utilization of many accessibility zones in the territory, monitoring, auto scaling, recovery and load balancing in the territory (Amazon Web Services, 2016).

Critical application must ensure every single points of failure are identified and assessed on the basis of application’s availability requisitions and risk profile. An efficient HA strategy will comprise not only the way of single component recovery but also which HA testing will be performed to ensure that application can retrieve as expected. Following web services can be implemented by the organization:

Automated Scaling for scaling and instance recovery.

Flexible Load Balancing for load balancing throughout compound availability zones.

Flexible IP Address for stagnant IP addresses which could be remapped between instances.

Database Mirroring for taking advantage of synchronized data application technology (Liao, Kuai & Leau,2015).

Backup and Disaster Recovery (DR)

Every application possesses certain disaster recovery requisites that need to be attached to the recovery points and recovery time purposes and geographical requisites that limit the physical nearness between disaster recovery and primary site. An efficient disaster recovery strategy will comprise single component recovery and the requisite disaster recovery testing that would be executed for assurance that the application could be retrieved as anticipated. At elevated level, an efficient DR strategy will include territorial redundancy, load balancing, territorial recovery, monitoring and universal traffic management. Following web services and practices that an organization can take into consideration as a part of DR strategy:

Store data or run multiple instances using multiple AWS region.

Data Log Shipping for leveraging asynchronous data duplication technology.

Preserve DR capacity in different territory through Amazon Reserved Instances.

Using intermediary tools to recover of lost data (Newcombe et al., 2015).

3. Taking into consideration the guidelines for the assessment of the service provider following things can be highlighted:

The service provider respects and encourages the professional wellbeing of its members and organizations, as well as the people they serve and promotes global evolution of the society.

The service provider acts with integrity, rationally and with good faith while serving and imparting values to its clients, employers and vendors (Mathew, 2014).

The service provider offers their high level of satisfaction by maintaining a standard level in its services and consistently acts towards improvement of the services by adding significance to knowledge and information they offer.

It consistently works towards the success of its clients by having a shared vision.

It respects the intellectual properties of its clients, competitors and informs its clients of possible ethical and legal contravention in the provision of services (Mathew, 2014).

4. Opportunities of Remote Administration

Increased Efficiency and Time Saving: Remote administration helps in increasing the overall efficiency by reducing expenditures and saving time the business can allocate their vital resources somewhere else. With an automated IT infrastructure for tracking the performance, all system under monitor is evident on central console offering the organization actual time information.

Receive Proactive Measures: The most vital advantage that remote administration offers is that it helps in monitoring the activities 24/7 and helps in sending an alert whenever there is any irregularity in the network and can be addressed within no time (Bhatt & Choksi, 2013).

Risks of Remote Administration

The only major risk that any organization faces is the risk of cyber threat. With increase in cloud computing and remote administration, the threats of potential cyber attacks have also increased over time. Cyber criminals always seek to breach the security protocol of the companies and acquire critical information of the company (Bhatt & Choksi, 2013).
