Flashcards

What is Cloud Computing?

A computing model that provides on-demand access to resources like servers, storage, and software over the internet. This allows for flexible scaling and pay-as-you-go pricing.

Traditional Procurement Process

The traditional way of acquiring computing resources where companies purchase hardware and software upfront. It involves planning for future needs and potential inefficiencies.

Cloud Computing Use Case

The process of using cloud computing for a specific task or service. It involves leveraging the cloud's flexibility and scalability to meet changing demands.

Under Capacity

The challenge of having too little computing power for your needs. This results in poor performance and can impact user experience.

Cloud Computing Concepts

  • Traditional Procurement Process: Traditional systems often "buy first, use later," purchasing server capacity in advance. This may result in under-utilization or over-capacity and thus inefficient spending.
  • Cloud Computing Use Case: In contrast to traditional models, cloud computing scales on demand, allowing for temporary increases in capacity for events like holiday shopping by resellers, and avoid wasting resources on unused capacity.

What is Cloud Computing?

  • On-demand delivery of computing power, databases, storage, networking, software
  • Uses the internet to deliver services
  • Pay-as-you-go pricing
  • No upfront infrastructure investment
  • Provision exactly the right resources as needed

NIST Cloud Computing Model

  • Shows essential characteristics and service models of cloud computing.

Essential Cloud Characteristics

  • On-demand self-service
  • Broad network access
  • Resource pooling
  • Rapid elasticity
  • Measured service

On-Demand Self-Service

  • Services consumed as needed, without human intervention from the cloud provider.
  • Organizations provision resources (servers, storage, web apps) when needed.
  • Organizations can provision resources using their internal IT staff.

Broad Network Access

  • Cloud resources accessible across a network.
