As test day for the Security+ SY0-401 approaches, I thought it would be good to include a few cloud computing service terms for review.

PaaS – Platform as a Service

  • This service is for users who want some control in their hosting or development
  • Reduces the need for staff to worry about full infrastructure worries
  • It could be niche but in the very least it is a platform that is optimized to work with specific setups
  • Platform delivers servers, operating systems, storage, networks, and the like
  • Think of this as middleware

IaaS – Infrastructure as a Service

  • This service is for users who want complete control in their hosting or development
  • Reduces cost of having on premises hardware, SLA and BC responsibilities, and vendor support contracts
  • Infrastructure delivers full use of provisioned hardware, servers, storage, networks, and the like for staff
  • Third party is often in charge of routine maintenance and software patching though

SaaS – Software as a Service

  • This service is for users who do not need a setup for hosting and development
  • Reduces time and operation cost
  • On-demand software that’s centrally hosted and easily managed on a subscription
  • The Adobe suite is kind of like this, even though there is software that runs locally on your computer
    • Other popular software includes email service providers and MMOs games

Conclusion

That's it for cloud computing service terms. Let me know what else you needed to learn in this topic.
