What and Why Kubernetes

Kubernetes basic:

Interesting background: 

• Kubernetes originates from Greek, meaning helmsman or pilot.
• K8s as an abbreviation –> counting the eight letters between the “K” and the “s”.
• Google open-sourced the Kubernetes project in 2014.
• Kubernetes combines over 15 years of Google’s experience running production workloads at scale with best-of-breed ideas

Whats it is:

• Ultimate management for containers
• Open-source platform with wide community
• Portable, extensible and growing ecosystem

Deployment solution:

Old days vs VMs vs Container:

Old era:
– Physical server with limitation for each app for required resources such as CPU, memory.
– Requires multiple machines for different apps

VMs :
– Runs multiple VMs on a single physical machine
– Allows better utilization of resources, costs and isolation of apps

Containerization:
– Same as VMs but lightweight due to shared OS properties
– Comes with lots of features for devops, best fit for micro-services
– Scaling and automatic failover mechanism
