What is Cloud?

Cloud services are getting very popular these recent years, most big tech companies store their data on the cloud,  cloud services are making data storage more accessible to users as of 2019 many users are moving to the cloud and knowing about the cloud system is essential. 

What is the Cloud?

Cloud refers to the online storage of data, i.e,  your upload your data online, so that even if you don't have access to your device from which you uploaded the data, you can still access the data from any device because it is stored in servers online. 

Why cloud computing is growing?

Cloud computing is getting very famous and is going to further increase its potential. Many companies like Google, Amazon, and Microsoft provide cloud services.  Most users could not access their data when they accidentally lost their data or damaged their computer but when you store your data(Photos, Videos, files, any software) online( When I say online it is synonymous to storing data on the cloud) you can access them from anywhere from any device(Andiod, Apple device, etc).

All you need is an internet connection and you can access your data from the cloud.

Cloud computing is the delivery of computing devices-  including servers, storage, databases, networking, software, analytics.

There are three types of Cloud computing

There are different types of cloud services each one is different according to the user needs, one type of cloud service cannot be right for everyone so, depending on the scale you use there are three different types of cloud services.

1.PUBLIC CLOUD: Private cloud are those that are provided by third-party owners, they provide services like servers and storage over the internet.  ALL the storage, software, the hardware is managed by the cloud provider. You can manage and use these using a web browser. These services are also known as Iaas(Infrastructure as a service). eg: Microsoft Azure, AWS, etc.

2.PRIVATE CLOUD: Private cloud refers to the services used by one organization. Data is not shared and cannot be accessed by any individual, data security is high in this type of service.

eg:  VMWare, Openstack.

3.HYBRID CLOUD: This type of cloud service uses both Public as well as Private cloud, allowing data and technology to be shared between them. This type of service gives more flexibility and more deployment options. 
eg. COMBINATION of both private and public.

Types of cloud services. (Iaas, Paas, serverless and Saas)

1. Iaas(Infrastructure as a service):  This is also the most basic cloud computing service. With this service, you rent IT infrastructure Virtual Machine, Network, Storage, operating system from a cloud provider on a pay basis.

2.Paas(Platform as a service):  This type of cloud computing service supplies an on-demand environment for developing, testing and delivering and managing software applications. It is generally used for software development.

Common PaaS providers include Salesforce's Force.com, AWS Elastic Beanstalk, and Google App Engine.

3. Serverless; This type of service cloud-only focuses on tasks like building app, software or image processing without thinking about server management. The cloud provider handles the management of the storage capacity and server management for you.

Google Cloud Functions and Azure Functions are examples of serverless computing services.

4. Software as a Service(Saas):  This type of cloud service is used for delivering sofware applications on the cloud. Cloud providers provide the software and handles all the maintenance like software updates and security patches. Microsoft 365 is an example of this service.
