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.
