LO1. Demonstrate an understanding of the fundamentals of Cloud Computing and its architectures
P1. Analyze the evolution and fundamental concepts of Cloud Computing.
I. What is cloud computing?
− Cloud computing is an all-encompassing service that provides IT as a service. It's an Internet-
based computing solution that provides shared resources, similar to how electricity is
distributed on the grid. The cloud's computers are set up to work together, and the various
applications make use of the combined computing power as if they were running on a single
machine.
− The ability of cloud computing to be flexible is based on the ability to allocate resources on
demand. This allows the system's total resources to be used instead of having to assign
specific hardware to each task. Websites and server-based applications used to be run on a
single system before cloud computing. Resources are aggregated as a virtual computer with
the advent of cloud computing. This combined configuration creates an environment in which
applications can run independently of any specific configuration.
II. Why the rush to the cloud?
− The cloud computing paradigm shift has valid and significant business and IT reasons. The
basic principles of outsourcing as a solution are applicable.
− Reduced costs: Cloud computing can reduce both capital and operating expenses (CapEx and
OpEx) because resources are only acquired and paid for when they are used.
− Cloud computing allows valuable personnel to focus on delivering value rather than
maintaining hardware and software, allowing them to focus on what they do best.
− Robust scalability: Cloud computing allows for immediate scaling, either up or down, at any
time without long-term commitment.
III. Benefits of cloud computing
− One of the best things about cloud computing is that it is not an all or nothing approach.
− Companies can choose to use cloud resources as much, or as little, as necessary to fulfil their
needs.
− Let's learn some of the benefits of cloud computing.
1. It is cost-effective
−Cloud computing provides a pay-as-you-go model, which means that you only have to pay
for the resources that you use. This model brings with it many benefits, including.
• There is no upfront cost.
• You do not need to buy hardware and infrastructure.
• You do not need to maintain the hardware.
• You can stop paying for resources that are no longer needed.
• It leads to better cost prediction.
2. It is scalable

Page 9
−You can increase or decrease the resources and services at any given time according to your
needs. You can scale your resources both vertically and horizontally according to your need.
• Vertical scaling, also known as “scaling up”, refers to adding resources to increase the
power of an existing server. For example – adding more GPUs or adding more memory.
• Horizontal Scaling, also known as “scaling out”, refers to adding more servers that
function together as one unit.
3. It is reliable
−Cloud providers often provide services like data recovery, disaster recovery and data
replication services, as data is the most crucial information and cloud providers help to
secure it.
−It is achieved through data redundancy.
−So, if one component fails, a backup component will take its place.
−This is known as fault tolerance.
4. It is secure
−You have physical security – The data centres are equipped with walls, cameras, security
personnel, gates, and so on to protect their assets.
−You have digital security – The cloud providers make sure that your data is secure from any
potential threats and unauthorized users.
5. It is global
−Most cloud providers have fully redundant data centres in various regions throughout the
globe allowing you to replicate your services into multiple regions for redundancy and
locality.
6. It is current
−The cloud hardware is maintained and upgraded by the cloud providers and you can focus
on what matters: building and deploying applications.
7. It is elastic
−Your cloud computing system can compensate for workload changes due to spike or drop-
in demand by automatically adding or removing resources.
−For example – Imagine your website experiences a sudden spike in traffic due to some
reason. The cloud will automatically allocate more computing resources to handle increased
traffic.
−When the traffic is normalised the cloud will automatically de-allocate additional resources
to minimise cost.
III. Main service models of cloud computing
1. Software-as-a-Service (SaaS)
−SaaS applications are the applications that are hosted on cloud servers and users access
then over the internet.

Page 10
−SaaS is just like renting a fully furnished house: you get to use it as your own, but it is still
owned by your landlord.
2. Platform-as-a-service (PaaS)
−PaaS is a kind of service in which the vendor offers you everything you need to build your
application like development tools, infrastructure, operating system.
−You get a complete environment to build, test and deploy your
−application.
−Example: Microsoft Azure, Heroku, Google App Engine
3. Infrastructure-as-a-Service (IaaS)
−It is the most flexible kind of cloud service.
−In this kind of service, a company rents the infrastructure and storage they need from the
cloud vendor and then use that cloud infrastructure to build their application.
−IaaS is like leasing land on which you can build whatever you want.
−Example: Digital Ocean.
4. Function-as-a-Service (FaaS)
−Function as service is also known as serverless computing.
−The main idea behind serverless computing is that your application is broken down into
separate functions that run when triggered by some action.
P2. Design an appropriate architectural Cloud Computing framework for a given scenario.
I. Analysis the technical challenges:
− In recent years, researchers have conducted surveys to gather information about the current
challenges of cloud computing. Since then, risks have risen to the top of the priority list.
1. Security issue:
− In terms of data security, we have no way of knowing where your data is stored or
processed. This raises the possibility of cloud computing risks during deployment or
management.
− This makes it difficult to entrust sensitive and proprietary information to a third party,
highlighting the difficulties of cloud computing.
2. Cost management and containment:
− The cost of cloud computing is one of the next risks.
− An organization can easily expand its processing capabilities in the cloud without having
to invest heavily in new hardware. Instead, businesses can use public cloud providers' paid
models to access additional processing. However, because cloud services are on-demand
and scalable, it can be difficult to quantify and predict quantities and costs.
3. Lack of resources/expertise:
− The lack of specialized resources is one of the cloud challenges that companies and
businesses are facing today.
