2. What is AWS Cloud Computing
Cloud computing refers to the delivery of computing services, including servers, storage, networking, databases, analytics, software, and more, over the internet (“the cloud”), (Amazon Web Services, n.d.).
Instead of owning and managing physical hardware, users can access and use these resources on-demand from a cloud service provider., such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS) (Amazon Web Services, n.d.).
3. Types of Cloud Services
- Infrastructure as a Service
- Platform as a Service
- Software as a Service
Each type of cloud computing provides different levels of control, flexibility, and management (Amazon Web Services, n.d.).
Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet.
In an IaaS model, users can rent virtualized hardware, such as virtual machines, storage, networks, and other infrastructure components from a cloud service provider (Amazon Web Services, n.d.).
Platform as a Service (PaaS) is a cloud computing model that provides a platform and environment for developers to build, deploy, and manage applications over the internet.
In a PaaS model, the cloud service provider manages and maintains the underlying infrastructure, including servers, storage, and networking, allowing developers to focus solely on writing and deploying code (Amazon Web Services, n.d.).
Software as a Service (SaaS) is a cloud computing model that delivers software applications over the internet on a subscription basis.
In this model, the software is hosted and maintained by a third-party provider, and users can access it via a web browser or a specialized application (Amazon Web Services, n.d.).

- AWS Lambda
- AWS EC2
- AWS Storage Gateway
7. AWS Lambda
AWS Lambda is a sеrvicе that allows you to еxеcutе codе without worrying about sеrvеr managеmеnt.
It opеratеs basеd on еvеnt triggеrs, such as filе uploads, databasе changеs, or HTTP rеquеsts, which automatically invokе codе.
AWS Lambda automatically scalеs to handlе workloads, еnsuring your application is rеsponsivе.
This sеrvеrlеss modеl is cost-еffеctivе, as you only pay for thе timе your codе runs, еliminating idlе sеrvеr costs. It simplifiеs application dеvеlopmеnt by abstracting infrastructurе managеmеnt.
Key features and characteristics of AWS Lambda:
- Serverless
- You don’t need to worry about server provisioning, scaling, or maintenance. AWS Lambda automatically manages the infrastructure for you.
- Event-Driven
- AWS Lambda is designed to respond to events. It can be triggered by various AWS services, custom applications, or HTTP requests using Amazon API Gateway.
- Supported Runtimes
- AWS Lambda supports multiple programming languages, including Node.js, Python, Java, Go, .NET Core, and more. You can use your preferred language to write your functions.
- Scalability
- AWS Lambda scales automatically to handle a high volume of requests. You don’t need to configure the scaling behavior.
- Stateless
- AWS Lambda functions are stateless, meaning they don’t maintain server-specific information between invocations. This makes it easy to run functions in parallel.
- Integration
- You can easily integrate AWS Lambda with other AWS services to build serverless applications and microservices.
- Custom Code
- You can write custom code to perform specific tasks and execute business logic in response to events. AWS Lambda provides a range of deployment options for your code.
(Amazon Web Services, n.d.).
8. AWS EC2
Amazon Elastic Compute Cloud (Amazon EC2) is one of the core services offered by AWS. It provides resizable compute capacity in the cloud referred to as “instances”.
EC2 enables users to run instances on the AWS cloud infrastructure, allowing users to have full control over the virtual server’s configuration and scalability.

- Various Instance Types
- Can be optimised for specific workloads and requirements (CPU, memory, storage and network performance)
- Operating System Flexibility
- Supports Amazon Linux, Windows, Ubuntu and more
- Security Groups
- Virtual firewalls that control inbound and outbound traffic to EC2 instances
- Elastic IP Addresses
- Elastic IP addresses are static, public IP addresses that you can assign to an EC2 instance
- Elastic Block Store (EBS)
- Instances can be attached to EBS volumes for storage
- Auto Scaling
- A feature that automatically adjusts the number of EC2 instances based on define criteria, such as CPU utilisation or network traffic
