Study Notes

Cloud Computing

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., servers, storage, applications, networking, and services).
These resources can be rapidly provisioned and released with minimal management effort or service provider interaction.
It leverages virtualization and distributed systems to provide scalable and flexible resources to users.
Key characteristics include: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

SaaS (Software as a Service)

SaaS is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted.
Users access software applications over the internet without needing to install or maintain software on their local devices.
SaaS providers manage the infrastructure, software updates, and security.
Examples include Salesforce, Google Workspace, and Microsoft 365.
Key benefits include: reduced upfront costs, increased flexibility, and automatic updates.
Downsides include: potential vendor lock-in, limited customization, and reliance on internet connectivity.

PaaS (Platform as a Service)

PaaS provides a platform for developers to build, run, and manage applications without the complexity of handling the underlying infrastructure.
It offers pre-configured environments, tools, and APIs that developers can utilize to build and deploy applications.
PaaS providers handle server management, operating systems, and databases, allowing developers to focus on application logic.
Examples include AWS Elastic Beanstalk, Google App Engine, and Microsoft Azure App Service.
Typical users are application developers needing a platform to build, run, and manage their applications quickly and efficiently without the heavy lifting of managing an underlying infrastructure.
Advantages often include rapid development cycles, streamlined deployment, and automatic scaling capabilities.
Possible shortcomings are vendor lock-in and limited control over the underlying infrastructure.

IaaS (Infrastructure as a Service)

IaaS is a cloud computing model that provides virtualized computing resources (servers, storage, and networking) over the internet.
Users have greater control over the operating system, storage, and deployed applications.
Customers essentially rent the underlying IT infrastructure, such as servers, storage, and networking components, while having the responsibility for managing the operating systems, applications, and data.
Examples include Amazon Web Services (EC2), Google Compute Engine, and Microsoft Azure Virtual Machines.
Key benefits are high control, flexibility, and cost-effectiveness for certain workloads.
Drawbacks might be management complexity and responsibility for security configurations.
End users benefit from pay-as-you-go pricing, scaling resources up or down based on demand.
