🔰 Create a Setup so that you can ping google
but not able to ping Facebook from same system..

In the first step we check connectivity that our system in pinging to google and Facebook .

With the help this command .


We can ping to google successfully .

Now we check connectivity for facebook.

with the help this command .


In this we are going see a product named as kubernetes and what is it ,why we use this, how it is solving problem in the industry .

Kubernetes is a Greek word for helmsman or container of a ship .

Kubernetes is also known as k8s because there are 8 letters between k and s in

the word Kubernetes .

Kubernetes is a container management(orchestration) tool . it is developed by Google lab and later denoted to CNCF (cloud native computing foundation) .it is open source means anyone can do changes in this code . …

🌀 7.1: Elasticity Task

🔅Increase or Decrease the Size of Static Partition in Linux.


for doing this task first we add a physical disk to the virtual machine

OF 10 Gib

for confirming disk is attached or not .

by fdisk -l command

🌀 7.1: Elasticity Task

🔅Integrating LVM with Hadoop and providing Elasticity to DataNode Storage

steps :::

first we make hadoop cluster storage elastic means we can increase the storage in the datanode on run time by using the concept of lvm

first we start the services of name node and data node and lets see how much storage does data node give .

as we see how much storage data node give to name node.

now our next step is to increase the storage of data node so that it give more storage to name node .

so for doing…

🔰 Create High Availability Architecture with AWS CLI 🔰

🔅The architecture includes-

- Webserver configured on EC2 Instance

- Document Root(/var/www/html) made persistent by mounting on EBS Block Device.

- Static objects used in code such as pictures stored in S3

- Setting up Content Delivery Network using CloudFront and using the origin domain as S3 bucket.

- Finally place the Cloud Front URL on the webapp code for security and low latency.



By using the aws cli command by using the key name “gautam”

aws ec2 run-instances — image-id ami-0e306788ff2473ccb — instance-type t2.micro — count 1 — subnet-id subnet-88c8c1e0…

🔅Configuring HTTPD Server on Docker Container

🔅Setting up Python Interpreter and running Python Code on Docker Container


first we configuring webserver we need operating system ,so we launch a docker container with the help of an image/dvd .

Docker is a tool of containerization technology by using this technology we can launch any os in instant time with the help of os image.

we launch os with the help this image .in docker we have a command fot checking how many images we have .

with the help of centos image with latest version we install…

Following are the steps for doing this task .

Step 1. We create a new key pair using the command

Aws ec2 create-key-pair -- key-name

We create key by Gautam name and let’s that we have any key name by such name Gautam already created or not.

In this pic we don’t have any key by Gautam name .

And let’s create key by using the following command .

Let’s first understand what is machine learning ?

Basically machine learning is a branch of artificial intelligence ,we write code in some language like python , for creating a particular model , and give data to that model and model analyse the data, find mathematical relationship between the data and predict new things what we want ,with the help of mathmatical formula (by analysing the relationship between data).

Real life use cases of machine learning .
