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 over their hosting or development.
- Reduces the need for staff to worry about full infrastructure worries.
- It could be niche, but at the very least, it is a platform optimized for specific setups.
- The 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 of their hosting or development.
- Reduces the cost of having on-premises hardware, SLA and BC responsibilities, and vendor support contracts.
- Infrastructure fully uses provisioned hardware, servers, storage, networks, and the like for staff.
- However, third parties are often in charge of routine maintenance and software patching.
SaaS - Software as a Service
- This service is for users who do not need a setup for hosting and development.
- Reduces time and operation costs.
- On-demand software that’s centrally hosted and easily managed on a subscription.
- The Adobe suite is similar, even though there is software that runs locally on your computer.
- Other popular software includes email service providers and MMO games.
Conclusion
That's it for cloud computing service terms. Let me know what else you need to learn on this topic.
