Cloud Deployment Models

  • A private cloud environment is supposed to utilize mainly by a single company. In that model, data-center is accessible off-site or on-premise. Usually, it’s utilized by the companies to host extremely crucial info and data. 
  • In public-cloud, companies are sharing server space. Many of the Info-Tech services are based on the public cloud.
