An Overview of Cloud for Beginners
Today, a lot of people & companies use the tech term “Cloud”. Firstly, we need to understand what is a cloud? Cloud is not physical, it is a network of servers that are connected to each other. These servers provide online services & allow them to store data and access it, like google drive, dropbox, adobe creative cloud, etc. We use the cloud in our daily life.

Cloud Deployment Models
There are three types of cloud deployment models.
1. Public Cloud
2. Private Cloud
3. Hybrid Cloud
1. Public Cloud
In this model, services are available over the internet for public use. Service providers own & manage this cloud model which may be free or subscription fee required. For example, Amazon web services (AWS) offers online services, Dropbox- a storage space for personal files, google cloud services, facebook cloud service, etc.
2.Private Cloud
Security & privacy is the main concern for every company. A private cloud provides hosted services to limited people or organizations. This model provides the highest security & control level. You can access your data from your laptop, mobile device, or tablets with an Internet connection.
There are two types of private cloud.
A) On-Premise: This cloud is hosted & managed within an organization own facility. It is best for security because one has full control over the cloud system.
B) Externally Hosted: This type of cloud is hosted & managed by a third party. It offers total privacy because you don’t need to share resources.
3. Hybrid Cloud
A hybrid cloud is a combination of public & private clouds. A hybrid cloud offers the benefits of multiple deployment environments in which the company provides and manages some resources in-house and has other resources provided externally.
