Task: Multi-Tenancy Cloud with a Secured Logical Isolation Storage
1.Proposed topic:
In 100 words identify a proposed topic in your discipline?
Users of a public or private cloud can pool their computing resources in a multi-tenant cloud. Each renter’s personal information is confidential and not accessible to other residents. In a multi-tenant cloud infrastructure, users can store their projects and data. Multi-tenant cloud architecture has several permission levels to ensure users have exclusive access to their data and prevent other cloud tenants from accessing it. If the cloud provider permits you, you may access a tenant’s data (M.V., 2018). Numerous companies can share a single server in a private cloud, but multiple organizations can securely share a single server in a public cloud. In a multi-tenant cloud, more than one user can access the same virtual machine at once. This means that businesses may run fewer servers for less money, making it easier to keep them up and running.
2.Theoretical Background:
What theories covered in the program are associated with your topic?
Theories associated with multi-tenancy cloud storage and logical isolation include information security, access control, and data management. These theories are essential for understanding how to securely store data in a shared environment and ensure that only authorized users can access it. Storage cloud solutions realize economies of scale by serving many customers from a single pool of disks and servers. A single device will be used to hold the information of many different renters (Agade et al., 2012). All tenants’ report is available to a single app, which can then verify a user’s identification and authorization before completing the requested action. A single cloud flaw could compromise all renters’ data. The cloud is considerably less safe than dedicated physical resources because security is only supplied at the application level. For multi-tenancy environments, we offer Secure Logical Separation for Multi-tenancy to achieve security comparable to physical separation while allowing complete sharing of resource usage (SLIM).
3.Population and sampling
What is the population you would like to address? Where will you select your sample from?
The companies thinking about adopting a multi-tenant cloud with protected logical isolation storage are the audience I would like to reach with the information I am trying to spread. To get a sample that is indicative of the whole, I would look for businesses already utilizing cloud services but are interested in increasing the level of safety they offer their customers. Young people in the United States who are just starting in information technology would benefit tremendously from my study’s findings. We would use a range of methods, such as questionnaires, focus groups, and individual interviews, to obtain the data we need (Rowley, 2014).

ASSESSMENT 1 BRIEF Subject Code and Title MIS602 Data Modelling and Database Design Assessment Modelling Report Individual/Group Individual Length N/A Learning Outcomes The Subject Learning Outcomes demonstrated by successful completion of the task below include: a) Examine the role of data in an organisation, and develop solutions related to the creation, storage and management of organisational data. c) Apply contemporary database modelling to identify and address anomalies in data and recommend solutions. Weighting 30% Total Marks 100 Marks Task Summary This assessment requires you to prepare a modelling report that demonstrates your ability to assess business requirements along with a logical design that could be implemented in a relational database management system. Context When preparing to implement a new information system, it is essential that the initial design is well thought out from the outset. Modifying the database after implementation can often be an expensive process in terms of time, effort and cost. Often the first engagement step is to conduct interviews and workshops with end users and business subject matter experts to get a better understand of how the business runs. The output of these workshops becomes the foundation for the database design. Task Instructions

“CDVD enter prises” is a customer driven optical storage m edia producer making about
90.000.000 CDs, Blu -rays and DVDs per year serving about 31.500 different customer s.
Production is divided into five sections: pre -manufacturing, manufacturing, graphics, printing and
packaging. In general, the production can be described as follows:
Pre -manufacturing : Each customer sends an email (or a CD) containing the data to be reproduced
by CDVD enterprises. This data is written to a unique mould a so -called “stamper” which is us ed
to make a disc ingot for further replication. The stamper consists of silicone or glass with a
diameter of about 20 centimeters. The data is written to a silicone – or glassmaster with a laser
beam that “records” the information that is going to be replicated . The information is recorded to
the disc by producing tiny indentations to the polycarbonate known as “pits” and “lands”.
Manufacturing: After the stamper is made the disc replication starts by using molding machines.
Here a syringe injects a he ated liquid polycarbonate (approx. 360 degrees Celsius) producing the
disc which already contains digital information, but cannot be scanned since at this stage the disc
is completely transparent . After a short cooling of the disc , one side of the disc (co ntaining the
information) is covered with a silver, aluminum or gold layer and thereafter is covered with
lacquer which reflects the laser beam in order to read the information from the disc. After a
quality inspection the discs are collected on a spindle.
Graphics: Within the graphics department the covers of the discs are produced according to the
customer’s provided graphic design. Here print stencils are made for the different printing
technologies (serigraphy or offset printing).
Printing: Depending on the quality requirements (high quality offset) the di scs are printed at a
serigraphy – or an offset machine. The difference between these two techniques is mainly that for
the serigraphy printing machines the mesh has to be cleaned after eac h order and that the colors have to be prepared beforehand. The offset printing machines contain the CMYK (cyan, magenta,
yellow, black) colors and therefore only the stencils need to be changed after each order.
Packaging: Within the packaging department , all orders are sent to machines which are either
fully – or semiautomatic. Here the covers, booklets, inlays etc. are a dded to the discs and are
pack ed according to the customer’s need ( boxes, paper bags, trays, etc.).
Since t he pre -manufacturing and grap hics section are very flexible and do not state a planning
pro blem these two sections are not included in the following description. Figure 1 depicts the
workflow through the shop floor which is organized as a flexible flow shop.
Figure 1: Structure of the production system
Work flows from left to right, each product moves through these sections and i n t otal there are 35
machines on the shop floor. The manufacturing section is divided into two parts: CD and Blu –
Ray, DVD production (thereafter DVD) . These two parts consists of seventeen machines; six can
be assigned to the CD and eleven to the DVD division . The machines are fully substitutable
within the two segments which means all DVD -orders can be made on every DVD machine, but an DVD -order cannot be transferred to the CD part . The printing section is structured into three
parts since three technologies are available to print the media: serigraphy division (SD),
kammann – (KOD) and metronic offset division (MOD) . These three parts consists of ten
machines, six of them are serigraphy, three are kammann offset and one is a metronic offset
machine. The SD machines are partly substitutable and the KOD machines are fully substitutabl e.
The packaging section is structured into four parts, the V1 (CD boxes), V2 (shrinking), V3 (DVD
boxes) and V4 (paper, cardboard and plastic bags) packaging and consists of 8 machines (2 for
each part) whereas the machines in V1, V3 and V4 are partly sub stitutable and V2 machines are
fully substitutable. The production operates 16 hours per day , seven days a week in two shifts,
bottlenecks work stations are in the printing and packaging section due to the varying product
mix. The next section describes th e (production) planning tasks and problems at CDVD
enterprises .
2. Production planning and control tasks and problems at CDVD enterprises
In general, p roduction planning and control at CDVD enterprises follows a hierarchical approach.
Figur e 2 shows the hierarchical structure and the planning tasks at the company .
Figure 2. Planning tasks as described in Fleischmann et al. (2008) In the following we will focus on four different problems (problem sets) that the CDVD
enterprises faces. These problem sets should form the basis for student projects which should
develop models or techniques to improve the situation at CDVD enterprises.
2.1 Mid -term problem sets
1) Customer inquiry management
For customer driven manufacturers – like CDVD enterprises – an additional task is included
within the mid -term planning level, namely customer inqui ry management (also see figure 3 ).
Figure 3. Process of a customer driven company
At first, the customers inquiry at the company by stating the desired quantity of product(s)
(CD, DVD, Blu -ray and the corresponding type of packaging) and their desired delivery date.
Here, t he main decisions are whether to accept or reject the customer order s (order
acceptance/rejection) and whether the desired due date of the customer is feasible or whether it
should be renegotiated (due date assignment or also due date setting) .
1.1) Order acceptance/rejection – Problem set 1:
By now the employee in charge of customer inquiry management at CDVD enterprises does
not reject any order which , as a consequence, leads to overutilization of certain machines and
a low service level. Therefore, the task is to analyze the effect of rejecting orders and to show
the potential improvement of certain performance measures.
1.2) Due date assignment / due date setting – Problem set 2:
One has to differentiate between the external due date which is set by the customer (which
might be negotiable) and the internal due date which needs to be calculated by the company in
order to decide whether to accept the external due date. By now , CDVD enterprises uses forward scheduling to set the internal due d ate. Start ing with
the expected date that the customer places the order (Email with the data for the CD/DVD/Blu
ray production) they add a fixed planned lead time of 6 days (3 days production, printing and
packaging , 2 days transport and 1 day buffer) and thereafter accept or renegotiate the due date
with the customer . A major weakness of this approach is that the capacities of the production
departments are not taken into account and thus the 6 days (fixed) lead time are mostly a bad
estimation of the actual lead ti mes.
2.2 Short -term problem sets
2) Shop floor control: o rder release – Problem set 3 :
After order acceptance and due date setting all (accepted) orders are collected in an order pool
(see figure 3 above) . This order pool is a (digital list ) of orders provided to the production
planner who decides (each day) which orders to release to the shop floor .
At CDVD enterprises orders are automatically released by an infinite backward scheduling
approach. Thus, the release date is calculated by subtracting a fi xed lead time of 3 days from
the given (external) due date of an order. Capacities of the machines are not considered which
leads to time -varying loading and thus to changing utilization levels at the machines and as a
consequence to shifting bottlenecks . Thus, high WIP levels and therefore long lead times are
observed which, as a consequence, le ad to a poor service level . The management seeks for an
improved order release mechanism; they are especially fond of an order release mechanism
based on workload c ontrol.
3) M achine scheduling – Problem set 4:
On the shop floor , supervisors need to decide on the schedule of orders on specific machines
that is – allocating orders to resources at a specific time.
Especially at the printing department, scheduling of orders to the nine different printing
machines is important. By now, supervisors make scheduling decisions using a rule of thumb.
Thus the managers and the supervisors request a decision support tool for detailed scheduling
at least for the six serigraphy machines.
Extra problem set – supply of polycarbonate :
In order to guarantee a smooth production, polycarbonate need s to be on stock when needed,
acquired in time and in good quality. Currently, the responsible employee forecasts the
demand for polycarbonate over a planning horizon of 14 days. Therefore, she looks at the
order book, the stock of the material and uses his torical data (simple average) in order to
anticipate the demand. The company looks for an inventory control policy that determines a
reorder point and quantity (the mean lead time of the supplier is 3 days).

Advantages of Using Electronic Health Records (EHRs) in Storage of Patient Information
Computers are now a common presence in almost all aspects of human lives. They have changed the way people, interact, live, and work. One of the industries that have witnessed increased adoption of computing is healthcare in the form of electronic health records (EHRs). The electronic health record is a repository of all the patient medical information stored in an electronic platform in a way that can be stored and exchanged securely across multiple authorized users (Burke & Weill, 2018). The data stored is employed in the documentation of the patient state of health and care provided to them. The use of EHRs in healthcare are associated with numerous advantages.
The major advantages in the use of electronic health records are the reduction of medical errors, improvement of patient outcomes, improvement of clinical outcomes, and increasing the overall efficiency. Hoover (2016) points out that electronic health records (EHRs) have allowed the integration of technological features such as bar code scanning that allows physicians to provide correct medications to patients. This has reduced the chances of the wrong prescription, which has reduced the risks of adverse drug effects by 52%. The effective management of medications has resulted in improved patient outcomes over time. For example, laboratory results can be relayed in real-time, allowing the physicians to make timely decisions and request for further tests if need be. The use of EHRs has also improved legibility that has long been blamed for medication errors. The authors point out that in some cases, 60% of medication errors have been attributed to illegible handwriting. Finally, the EHRs has increased overall healthcare efficiency as it ensures medical examinations and drug prescription are synchronized.
Forms used to Keep Patient Information in EHRs
EHRs system offers a means through which different patient information can be collected and kept in different forms. The forms through which patient information can be stored in EHRs include the consent to treatment, the discharge, and the HIPAA consent forms. The consent to treatment form collects the information for patients that seek medical examination at the doctor’s office or those who are being admitted to the emergency room. The consent form provides the hospital and the doctor with express permission to provide treatment to the patient. The patient has a right to give consent when they accept the treatment or deny one if they refuse the treatment. The discharge forms are employed among those patients who have been in the hospital for more than 48 hours. The HIPAA consent form collects patient information showing their acknowledgment of the receipt of the Notice of Privacy Practices.
The Basic Workflow of a Health Care Organization Using EHRs The basic workflow in a health care organization using EHRs typically starts at the hospital’s primary care office. The primary care office typically has two front desk clerks, one nurse, and two primary care physicians (Pugh, 2019). In the primary care section, the process starts at the front desk where the patient’s appointment is………………………………………………………………………………………………
