What is Cloud

On-demand service of Compute power, database storage, application, and other IT resources

Its features are Pay-as-you-go Provisions for the right and required size of Computing resource that you need. You can access as many Resources as you need, almost Instantly. A simple way to access server, storage, database, and a set of application services

Traditional IT Overview

How the website works

Client -> Network -> Servers

It's just like a letter-sending process that has the address in the form of the IP address.

What are the Servers Composed of?

1)Compute=CPU

2)Memory = RAM

3)Storage = Data

4)Database = Store data in a structured way

5)Network = Router, Switch, DNS Server

Problems with the Traditional IT approach.

1)Pay for the rent for the data center

2)Pay for power supply, cooling, and maintenance.

3)Scaling is limited. Adding and replacing hardware takes time.

4)The deployment model of the Cloud.

Deployment Model of the Cloud

Characteristics of the Cloud

1)On-Demand Self Service.

2)Broad Network access.

3)Multi-Tenancy and Resource Pooling.

4)Rapid elasticity and scalability.

5)Measured Service.

Different Types of Cloud Computing

1) Infrastructure As A Service

• IAAS(EC2 Elastic Cloud Compute)

• Building block of the IT Infrastructure.

• Have access to networking, computing, and data storage classes.

• Highest level of flexibility.

2) Platform As A Service

• PAAS(Elastic Beanstalk)

• Remove the need for your organization to manage the underlying structure.

• Focus on the deployment and management of your application.

3) Software As A Service

• SAAS(Rekogintion)

• Complete Product that is run and managed by AWS.

AWS Shared Responsibility Model:

Define the responsibility of the user and AWS of the service

Pricing of the Cloud

AWS has 3 pricing fundamentals

Following the pay-as-you-go pricing model

1)Compute: Pay for the Compute time.

2)Storage: Pay for the data stored in the Cloud.

3)Data transfer OUT of the Cloud: Data transfer in the cloud is free

Conclusion:

Cloud computing is a pay-as-you-go, quickly scalable, on-demand service that offers a variety of IT resources. Traditional IT has drawbacks such as high expenses and constrained scalability. There are three types of cloud deployment models: private, public, and hybrid. Broad network access, multi-tenancy, and on-demand self-service are all features of the cloud. Software as a Service (SaaS) and Infrastructure as a Service (IaaS) are two examples of cloud kinds. Pricing for AWS is determined by computation time, data storage, and outbound data transfer. The company uses a shared responsibility approach.
