Introduction to AWS

Hi friends in this post we are going to introduce the AWS (AMAZON WEB SERVICES). Before starting the AWS we must know about the cloud technology. So what is cloud computing.

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Majorly the cloud computing is know as three different variant :

1. IAAS

2. PAAS

3. SAAS

IAAS refer to Infrastructure as a service , For example we are using any virtual machine on cloud , where we are able to install OS like linux or window etc. AWS elastic compute is best example of IAAS.

PAAS refers to platform as a service, here we are able handle all the stuff related to IT infrastructure like storage services , AWS S3 bucket is one of the example of PAAS.

SAAS refers to Software as a service, Here we are able to use cloud software like gmail, Facebook etc. These all are belongs to SAAS.

Next is types of cloud:

There we have three different type of cloud are there:

1. Private Cloud

2. Public Cloud

3. Hybrid Cloud

Private cloud means in-house cloud or DC where these business organizations build there own data centers. These data centers containing Network equipment, Servers, storage etc.

Where as Public cloud is same as private but public cloud is existed some where else on cloud and we can using the services of cloud via Internet or any VPN.

Now the Hybrid cloud is combination of both private and public cloud .

Hybrid Cloud

Why Cloud is best :

1. Time to Deployment

2. Easy to Enhance the Infrastructure

3. Maintenance

4. Elasticity

The best thing about cloud is that we required less time to construct any infrastructure according to our requirement. we can easily enhance the environment . It is easy to maintain.

So let's Start with AWS physical Infrastructure all over the world.

AWS has big infrastructure , Amazon has divided their structure into regions, Availability Zone, and DC .

AWS has 18 regions , 52 Availability Zone, Multiple DC.

Every Single region has multiple Availability Zone and Single AZ has multiple DC . You can find all information about the regions and zones at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html

So in next post i will going to share how to use free tier and IAM in AWS.

Thanks
