Here’s how Red Hat technology evangelist Gordon Haff explains Kubernetes in his book, “From Pots and Vats to Programs and Apps,”
Kubernetes, or k8s, is an open-source platform that automates Linux container operations. It eliminates many of the manual processes involved in deploying and scaling containerized applications.
Containerization: A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another
route -nTo view the routing table for your machine
nslookup google.comNow lets check the IP through which we are connected to google.com and facebook.com
nslookup facebook.comCheck connectivity with each IP
route del -net 0.0.0.0Use the above command to delete the neutral IP which allows the OS to ping to any public IP. Then check connectivity with google IP and facebook IP
You will find that you wouldn’t be able to reach to any
Now we can add google IP address that we obtained from nslookup cmd
route add -net 142.250.76.0 gw 192.168.29.1 netmask 255.255.255.0Now you would be able to ping google but not Facebook
Now lets again add the neutral IP for uninterrupted performance

To understand how first we need to know how much exactly is the data to be processed.
Let's take the example of a few MNCs
Google processes about 20 petabytes of data every data i.e. 10⁹ megabytes of data.
Facebook generates 4 new petabytes of data every data i.e. 10⁴ megabytes of data.
Amazon hosts about 1000 petabytes of data in their servers.
Our traditional databases or data storage methods are not compatible to store or process such are amount of data therefore a new term comes into the picture Bigdata.
What do we mean by “Big Data”?
Big Data refers…
