Cloud Deployment Models Flashcards
Public, Private & Hybrid
What are Cloud Deployment Models?
Defines where your data is stored, how customers interact with it and where applications run.
What is the Public Cloud?
- Most Common deployment model
- no local hardware to manage
- Share resources with other cloud users
What are the Advantages of public cloud?
- High Scalability/ agility
- Pay-as-you-go pricing
- Not responsible for hardware maintance or update
- Miminal technical knowledge
What are the disadavantages of the public cloud?
Specific security requirements that cannot be met by using public cloud
Government policies, industry standards, or legal requirements which public clouds cannot meet
What is the private cloud?
- Cloud environment in your own datacenter
- A simulation of a public cloud to users, but you remain completely responsible for the purchase and maintenance of the hardware and software services you provide.
What are the advantages of private cloud?
Ensure the configuration can support any scenario or legacy application
Control (and responsibility) over security
Meet strict security, compliance, or legal requirements
What are the disadvantages of the private cloud
- Initial capital expendeture costs
- Must purchase the hardware for startup and maintenance
What is Hybrid cloud?
- Combines public and private clouds
What are the advantages of hybrid cloud?
- Keep any systems running and accessible that use out-of-date hardware or an out-of-date operating system
- Have flexibility with what you run locally versus in the cloud
- Use your own equipment to meet security, compliance, or legacy scenarios where you need to completely control the environment
What are disadvantages of Hybrid cloud?
- More expensive than selecting one deployment model since it involves some capital expendature cost up front
- More complicated to set up and manage
