Cloud Providers: AWS, Azure, and Google Cloud Platform

Learning Objectives Define cloud computing and its five essential characteristics. Differentiate between the three main cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Compare the core compute and storage offerings of AWS, Azure, and Google Cloud Platform. Explain the architectural concepts of a 'Region' and an 'Availability Zone' for building resilient applications. Analyze a given application scenario and recommend an appropriate cloud service model. Describe the Shared Responsibility Model for cloud security.

TermDefinitionExample Infrastructure as a Service (IaaS)A cloud computing model where a provider hosts the fundamental infrastructure components, including servers, storage, and networking hardware. The user is responsible for the operating system and applications.Renting a virtual server like an Amazon EC2 instance, an Azure Virtual Machine, or a Google Compute Engine VM. You choose the OS (e.g., Linux) and install your own software, while the provider manages the physical hardware. Platform as a Service (PaaS)A model that provides a platform for customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure.Using a service like AWS Elastic Beanstalk or Google App Engine. You upload your Python or Java code, and the pla...

The Service Model Hierarchy Management Responsibility: IaaS > PaaS > SaaS. Abstraction/Ease of Use: SaaS > PaaS > IaaS. Use this pattern to decide which service model fits your needs. If you need maximum control over the operating system and environment, choose IaaS. If you want to focus only on your application code, choose PaaS. If you just want to use a finished software product, choose SaaS. The Shared Responsibility Model Provider is responsible for security *OF* the cloud. Customer is responsible for security *IN* the cloud. This is a fundamental security principle. The provider (AWS, Azure, GCP) secures the physical data centers, hardware, and core networking. The customer is responsible for configuring their services securely, managing user access, encryp...
