RedHat Expert Session on Kubernetes and Openshift

USE CASES I LEARN IN THIS SESSION

====> Importance of container in current agile world

====> How container adoption is growing rapidly in the enterprise 

===> container usage for production deployments in enterprise is still constrained by concerns regarding security monitoring data management and networking

====> Benefits and challenges of kubernetes

Benefits ----> scalability,workload portability,stability

kubernetes---->Deployment,Hardening,operations

====>Difference between baremetal virtualization containers

Baremetal ----> install the os on the top of hardware

virtulization----> Virtulization refers to the act of creating a virtual version of something in virtualization on the top of new software layer (hypervisor) install the OS

container------>contanization is the new virtualization on the top of docker engine install the os

====> why container technology is booming?

containers will allow applications to be easily shared and deployed

====> Difference between container and virtual machine

container:--> Guests share the same os "Typical boot time in Seconds"

Virtual machine:--> each guests as its own os "Typical boot time in minutes"

===>Infrastructure and applications of container

==> infrastructure<==

1)Linux operating system features,

2)Linux inside,

3)simpler and lighter than virtual machines

4)High density

5)Need orchestration and management

==>applications<==

1)A self contained package

2)easily add to already build applications

3)easily share containerized components 

=>How docker container as service platform

1) Build => Docker Toolbox

2) Ship => Docker Trusted Registry

3) Run => Docker universal Control Panel

=>what we need more than containers

1) scheduling 2)lifecycle and health 3)Discovery 4) monitoring 5)Authentication 6)Scaling 7) Networking 8) image registry 9) Metrics and logging

=>what is Redhat openshift container platform

ROCP is an open source container application platform based on the kubernetes container orchestration for enterprise application development and deployment

=>Features of openshift

1) pod scaling 2) high avalibility 3) choice of cloud infrastructure 4) responsive web console 5) Rich command line tool set 6)IDE integration 7)opensouce 8)operator hub 9)CI/CD 10) service mesh 11) serverless 12) application topology
