This blog provides the basic understanding of Cloud computing and Microsoft Azure system and its services. You can visit Microsoft link for detail knowledge, https://docs.microsoft.com/en-us/learn/modules/intro-to-azure-fundamentals/.
Cloud Computing-?
For creating, maintaining and delivery of any application,
we require different services like database, network, software, server,
storage. Cloud computing maintain all these services over the internet which
helps in lower operating costs, increases efficiency of infrastructure. End
user. only need to pay for the resources using in cloud which make it
cost-effective and resources can be added and removed anytime as per the user
need.
Microsoft Azure -?
Azure is cloud computing platform which provide multiple
services and by using these services, we can run new or existing application on
Azure virtual machine.
Type of Cloud Computing
There are mainly 3 type of cloud (Public, Private, Hybrid) based on accessibility.
- Public cloud in which data can be access and stored by anyone through internet. Although Public cloud is highly scalable, flexible, no maintenance by user and readily available at low cost, Its main disadvantage is reduction of security.
- Private Cloud in which organization creates its own cloud environment in datacenter and services are only accessible to particular organization users which increase high security and privacy. Only skilled labor is needed to manage the private cloud.
- Hybrid Cloud is the combination of both Public and Private Cloud and so, its makes it partial secure. Most common example of Hybrid cloud are Gmail, Google Drive, MS Office, Amazon web service.
There are 3 models which describe the different
responsibilities that cloud service provides.
- SAAS : Software as a Service
- PAAS : Platform as a Service
- IAAS : Infrastructure as a Service
Azure Services
