COSC2737 Assignment 2: IT Infrastructure in the Cloud.
In this assignment, you will combine 3 different cloud services
to build an application of your choice.
Typically, this might include a web-facing component. The
focus of the assignment is not this content, but
the infrastructure behind it – the “wiring”, if you will.
As part of the assignment, you will create a presentation video.
If this is done well, you will be able to add
these to a portfolio of work that you can demonstrate at job
interviews, etc….
NB. This assignment is focused on Amazon products, primarily
because that is what we teach in ITIS,
but, you are also allowed to use Google or Microsoft products,
or a combination – but only with prior
permission from the Course Coordinator. And we may not be
able to help you if problems between
vendor products arises.
For this assignment, you will provide a simple working cloud

implementation, and submit the contents in a
ZIP file to Canvas, along with a presentation video, a report,
and an initial PDF “pitch” document submitted
some weeks earlier than the deadline.
Note that the web content itself is not evaluated, only how it is
set up. So you can use material from
anywhere (as long as you cite it on the web pages).
List of Amazon Services: https://aws.amazon.com/products/
List of Amazon services available to AWS Educate:
https://s3.amazonaws.com/awseducate-starter-account-
services/AWS_Educate_Starter_Accounts_and_AWS_Services.p
df also available on Canvas.
Submission Details
1. Build a cloud infrastructure using at least 3 components from
the AWS list of products above:
1. This could be a server and storage, or compute, or whatever.
2. One of the components counted could be the use of Alexa
services for query.
2. The topic of the website is up to you, but must have a least
(say) 5 different pages, and must ideally
be some form of B2B flavour.
3. Submission will be the following:

1. Pitch Document – An initial “pitch” where you describe your
proposal in a few paragraphs
(not more than a page)
1. This will be due in week 11
2. Worth 5%, and will provide feedback from your tutor.
2. Report – A PDF report containing the following sections
1. Rationale
- The rationale behind this website or cloud construction. More
or less a copy
of the pitch in its final form.
2. Cost Estimates
- both development, fixed and cloud running and how these
running cost
scales for LOW (1-1000 transactions/day), MEDIUM (1000-
1,000,000), and
HIGH (above 1,000,000+ transactions per day) – hese costs all
to be
itemised and justified
- Imagine you are a professional quoting for the job
3. An installation manual that
- contains instructions to recreate the website(s)
- A marker should be able to rebuild it him/herself from this
4. There is no limit on report size, but a guide is about 10-15
pages including figures,

screen dumps, etc.
.

3. Content – a ZIP file containing all user and generated
content. Web/Cloud content itself not
to exceed (10MB).
1. Using the installation guide, a marker should be able to
reproduce your cloud
construction
4. Presentation
1. Video demo, to be included in the ZIP file, or URL to be
provided in the report.
Max video length: 10 mins. Try to do it for less.
Notes.
• Deadline in end of week 11 (pitch) and start of week 14
(content + video + report),
• Submission to be individual.

• Worth 5+25 = 30% of semester marks
• A more detailed rubric is availble which will further
demonstrate what is required.
• If a particular feature is obvious (such as builtin scalability),
it would be wise for you to mention this in
the report – just in case the marker did not see this.

Risk management techniques used in the oil and gas industries
Within the oil and gas industry there are inherent risks of
accidents occurring at any stage of the
process, from exploration through to the extraction, refining and
final delivery of the product.
These risks include fire, explosion, environmental
contamination and injury to personnel.

Oil and Gas Operational Safety: Safe Shift Handover
In the 1970s, shift patterns in the oil and gas industry gradually
changed from 8-hour to 12-
hour shifts. The view at the time was that inter-shift
communications improved because the
number of handovers was reduced, which in essence meant the
number of occasions when
critical information might not have been passed over was
effectively reduced.

of work in progress

Oil and Gas Operational Safety: Critical equipment controls
Emergency Shutdown (ESD) equipment and systems:
The petrochemical industry, both onshore and offshore,
processes large quantities of
hazardous material within a contained environment.
Consequently, it needs to have in
place systems which will either prevent loss of containment
from happening or mitigate
the consequences of such an event if it does happen.
ESD Functionality:

ESD Typical Actions:

-fighting controls (water deluge,
inert gas, foam system, water mist)
Safety Integrity Levels (SILs):
1 in 10 occasions and 1 in 100
occasions. It is required where the potential for relatively minor
incidents is involved with
limited consequential outcomes.
- Where the acceptable probability of failure is between
1 in 100 occasions and 1 in 1,000
occasions. It is required where the potential for more serious,
but limited incidents is involved
and where the consequences may result in serious injury or
death to one or more persons.

Drainage:
With any process or production facility there will always be a
residual amount of liquid that finds its
way to ground, or there will be a requirement for vessels to be
occasionally drained of liquids of some
sort so they can be maintained.

Oil and Gas Operational Safety: Furnace and Boiler Operations
1 Boiler and furnace:
Boilers are devices which heat large quantities of water in order
provide a constant supply
of hot water, or to turn it into steam. Where steam is generated,
this is captured and kept
in a pressurized state.
Furnaces, or process heaters, are devices which are used to
provide a large source of heat
to various process streams and are used extensively in the oil
and gas industry

and, as such, needs to be addressed as robustly as possible.

Oil and Gas Operational Safety: Marine transport
Case Example 1: Attendant/passing vessels hit the rigs
Mumbai High North Disaster: In 2005 the support vessel, MSV
Samudra Suraksha, was in the process
of transferring an injured worker to the Mumbai High North rig
for medical attention when strong sea
swells caused the vessel’s helideck to strike and sever one of
the gas export risers. Escaping gas soon
ignited and quickly developed into a fire which engulfed the
whole installation. Twenty- two crew
members were lost in the incident and the rig was completely
destroyed by fire after two hours, with
only the stumps of the jacket being left visible.
Case Example 2: Loading and unloading operation
On 8 January 1979, the oil tanker Betelgeuse was discharging
its cargo of oil via an offshore jetty at

Widdy Island in Southern Ireland. At about 1am a rumbling or
cracking noise was heard from the
vessel. This was followed, a short time later, by a huge
explosion. A further series of explosions
followed which broke the vessel in half. Much of the oil cargo
still on board ignited, and this fire
continued for a further 12 hours, after which time the vessel
sank at her moorings. Fifty people died in
the incident. It was determined that a faulty unloading operation
had unbalanced the vessel, causing it
to break its back and thereby rupture several of its empty ballast
tanks. Vapour from the ruptured
tanks then escaped into the vessel and exploded in a fire ball
when it found a source of ignition.
