Weighted Decision Matrix Analysis

The assignment content discusses a project that compares different hardware devices from various vendors, such as Asus, Synology, and Netgear, for new offices in Tokyo and Osaka. The goal is to select the best options based on requirements and specifications. The content also explores the concept of cloud computing and its advantages, including cost savings, increased productivity, and reduced maintenance needs. It proposes using cloud computing instead of maintaining on-premise hardware, highlighting the benefits of public clouds like Amazon Workspace.

WEIGHTED DECISION MATRIX
PROJECT PURPOSE:
The goal of project is to compare different hardware devices basically
switches, routers and PC from different vendors along with the
specifications and compare them together and select the best out of them that
suits our requirements and our needs.
I will compare here routers, switches and PC’s required for our new offices
in Tokyo and Osaka. I would be looking at various aspects that should fit to
the requirement and specifications given for this office
WDM-HARDWARE RESOURCE REQUIREMENT ANALYSIS
We will give weight and scores to different as per our needs and
specification and then select the best out of them.
WEIGHTS : IMPORTANCE GIVEN TO REQUIREMENTS
1 - Not Important
3 - Very Important
5 - Critical
SCORE- ASSESSING THE OPTIONS
0 – Not Meeting the expectation
2- Partially Meeting the expectation
4 Meeting the expectation
6 Exceeds the expectation

Proposal to use cloud computing to save company’s hardware, services
and energy cost.
Introduction
Cloud computing is the latest trend that is spreading in the market at very fast pace.
Cloud computing has helped companies to save hardware procurement and maintenance
cost and have boosted up productivity by spinning up the required hardware in few
seconds.
The following are the advantages listed below by using cloud computing: -
Hardware/Energy Cost
By using cloud computing you don’t have to procure any hardware for your organization.
The hardware needs to be purchased by the cloud provider and made available to you
using any thin client. This would definitely save time and procurement cost and also the
time that was spent to wait for the hardware to arrive and dependency on vendor.
Also this has definitely save space for keeping these hardware and cost of energy
required using this hardware.
Hardware Maintenance
Whenever we procure new hardware we buy an annual maintenance contract to maintain
the hardware, this can be completely eliminated using cloud. There will be no
requirement of maintaining the in house IT staff in case of any hardware troubleshooting.
Productivity Boost
The cloud software can be deployed quickly using the prebuilt AMI’s and can be ready to
use in some min. So once the software is ready then its immediately available for use and
employees can start working on that. Also since cloud are cost effective there is lots of
cost savings for software deployment and deployments are much faster.
Difference between public and private cloud

A) Replacing ALL workstations within the organisation with thin clients, which will
access a desktop environment provided by a cloud service provider (such as Amazon).
If we consider replacing all the desktop using thin client like Amazon Workspace it is
public and high end desktop comes cheap. User can access these desktop from any where
weather home or office. You can also select software which you require in your desktop
and the cost is very cheap. Also if we see company’s current contract its very high at
$800 where as amazon charges for its workspace as low as starting from $25/ month to
$78 for very high end configuration.
B) Replacing ALL workstations within the organisation with thin clients, which will
access a desktop environment provided by a private cloud infrastructure, created in-house
and based in Seoul.
If we consider replacing all the desktop with private clould architecture they won’t be
much scalable. No guarantee with uptime. Even using interface might not be easy.
Security will always be a concern and pricing might not be as cheap as amazon.
C) If we continue using on-prem desktop:-
There would be no ease of accessibility. We have to pay the maintenance charge as high
as $800 for each single PC. Cost of procuring, then time required to fix these machine if
they are not working. All these factors comes into consideration. So we need to definitely
move to cloud as soon as possible.
