Azure Fundamentals (Describe the differences between types of cloud computing )
Cloud computing :
Cloud computing is the delivery of computing services over the internet by using a pay-as-you-go pricing model. You typically pay only for the cloud services you use, which helps you:
Lower your operating costs. Run your infrastructure more efficiently. Scale as your business needs change.
To put it another way, cloud computing is a way to rent compute power and storage from someone else’s datacenter. When you’re done using them, you give them back. You’re billed only for what you use. Instead of maintaining CPUs and storage in your datacenter, you rent them for the time that you need them. The cloud provider takes care of maintaining the underlying infrastructure for you.
The Azure Top 10 Most Commonly used Categories.
There are 3 types of Cloud Computing Deployment Models. These are:
Private Cloud : On-premises/company-managed.
Public Cloud : Off-premises/cloud service provider-managed.
Hybrid Cloud : Combination of private + public cloud
The public cloud :
The most common cloud model is the public cloud. In a public cloud model, you use shared infrastructure that is accessible on a public network. The network, storage, and VMs that your application uses are provided by a cloud provider and shared between all consumers of the public cloud. Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform are examples of public clouds.
The private cloud :
The private cloud model provides many of the attractive benefits of the cloud (things like easy scaling and elasticity) in a private environment that is dedicated to a single company. A private cloud can be hosted in an on-premises environment, but it can also be hosted on a thirdparty hosting provider.
The hybrid cloud :
As you might expect, hybrid clouds are a mixture of public and private clouds.
compare and contrast the three types of cloud computing :
Public cloud :
No capital expenditures to scale up.
Applications can be quickly provisioned and deprovisioned.
Organizations pay only for what they use.
Private Cloud :
Hardware must be purchased for start-up and maintenance.
Organizations have complete control over resources and security.
Organizations are responsible for hardware maintenance and updates
Hybrid cloud :
Provides the most flexibility.
Organizations determine where to run their applications.
Organizations control security, compliance, or legal requirements.
