Specific Cloud Services
Specific cloud services within Amazon Web Services that I envision using in my cloud
computing strategy are Amazon Elastic Cloud Compute (EC2), AWS Cloud9, and Salesforce.
Amazon Elastic Compute Cloud (EC2) provides scalable computing capacity in the
Amazon Web Services (AWS) Cloud that works within the IaaS security model. Amazon EC2 is
used to launch as many or as few virtual servers as you need, configure security and networking,
and manage storage across the internet in a self-service manner (AWS, n.d.).
Within the PaaS service model, AWS Cloud9 is an integrated development environment
(IDE). It contains a collection of tools that you use to code, build, run, test, and debug software,
while helping you release software to the cloud. AWS Cloud9 offers a code-editor, debugger, and
terminal. Also, the support for several programming languages includes JavaScript, Python, PHP,
and more (Schleifer et al, 2010).
Salesforce, one of the most comprehensive customer relationship management (CRM)
platform, is a cloud-based software that helps organizations to effectively streamline their sales
and marketing operations within the SaaS service model. Salesforce and AWS have partnered up
expand their global strategic partnership that will make it easy for customers to use the full set of
Salesforce and AWS capabilities together to quickly build and deploy powerful new business
applications that accelerate digital transformation (Salesforce, 2021). Organizations from around
the world rely on Salesforce to manage their customer relationships and build new applications
leveraging the Salesforce platform, while using AWS for their compute, storage, and database
needs along with AWS technologies (Salesforce, 2021).

Security Responsibilities
IaaS
IaaS- or infrastructure as a service, is on-demand access to cloud-hosted physical and
virtual servers, storage, and networking – the backend IT infrastructure for running applications
and workloads in the cloud (IBM Cloud Education, 2021). This is provided to the consumer via
virtual machines accessible through the internet. Essentially, it is a virtual data center in the
cloud. IaaS is the lowest level of abstraction, meaning the consumer has a greater degree of
control, but also greater responsibility for security (Van der Vaart, 2021).
With Amazon EC2, AWS is responsible for “Security of the Cloud”. AWS is
responsible for protecting the infrastructure that runs all of the services offered in the AWS
Cloud (Torre & Maria, 2018). This infrastructure is composed of the hardware, software,
networking, and facilities that run AWS Cloud services.
With Amazon EC2, the customer is responsible for “Security in the Cloud”. Customer
responsibility will be determined by the AWS Cloud services that a customer selects. This
determines the amount of configuration work the customer must perform as part of their security
responsibilities. Customers that deploy an Amazon EC2 instance are responsible for management
of the guest operating system (including updates and security patches), any application software
or utilities installed by the customer on the instances, and the configuration of the AWS-provided
firewall on each instance (Torre & Maria, 2018).
PaaS
PaaS- or platform as a service, is on-demand access to a complete, ready-to-use, cloud-
hosted platform for developing, running, maintaining, and managing applications ( IBM Cloud

4COMPARING SAAS, PAAS, AND IAAS PRODUCTSEducation, 2021). Since the provider handles hosting and maintaining the infrastructure and
development platform, developers have more freedom to focus on building and running
applications. PaaS is also similar to other cloud computing services in which “hide servers” from
developers. Some of the most popular AWS services at this level of abstraction include AWS
Elastic Beanstalk and AWS Cloud9.
With AWS Cloud9, AWS is responsible for the privacy safeguards with services and
features that allows you to implement consistent and scalable processes to manage privacy,
including how data is collected, used, accessed, stored, and deleted (Torre & Maria, 2018). Also,
AWS provides a wide variety of best practice documents, training, and guidance that you can
leverage to protect your data.
With AWS Cloud9, the customer is responsible for managing the privacy controls of the
data, control how the data is used, who has access to it, and how it is encrypted (Torre & Maria,
2018).
SaaS
SaaS- or software as a service, is on-demand access to ready-to-use, cloud-hosted
application software (IBM Cloud Education, 2021). SaaS is the highest level of abstraction most
widely-known and understood by the general population, given most people interact with SaaS
applications on a daily basis (Van der Vaart, 2021). For example, Netflix, Salesforce, or
Slack. SaaS removes the need for organizations to install and run apps in their own computers or
data centers and usually offers flexible payment structures, scalable usage, and automatic updates
(Van der Vaart, 2021).

With Salesforce, AWS is responsible for embedded AWS services for voice, video,
artificial intelligence (AI), and machine learning (ML) into its new applications for sales, service,
and industry vertical uses (Goodison, 2021).
With Salesforce, the customer is responsible for buying prebuilt, out-of-the-box solutions
from Salesforce and use the integrated AWS services on a pay-as-they-go basis. Customers, for
example, could activate virtual call centers and empower sales teams with Amazon Connect and
AWS AI/ML services pre-integrated into Salesforce’s Sales Cloud and Service Cloud (Goodison,
2021).

While considering auto scaling and other cloud features, t2.micro EC2 instances are
part of the “T” instance family that are low-cost, general purpose instance types that provide a
baseline level of CPU performance with the ability to burst above the baseline when needed.
T2.micro instances are one of the lowest-cost Amazon EC2 instance options and are ideal for
a variety of general-purpose applications like micro-services, low-latency interactive
applications, small and medium databases, virtual desktops, development, build and stage
environments, code repositories, and product prototypes (Vantage, 2021).
