[TBD]Hybrid cloud: A seamless reality with Kubernetes

Introduction

Laymen explanation

Most companies existing from decades have their own IT infrastructure. Cloud offering is very well suited for them, but they like either

• seamless migration or

• co-existent solution which can re-use their existing infrastructure and also it should easy to do

Second approach is good as it will be less disruptive and also it can help to become cloud-native incrementally.

Kubernetes has provided way to make it happen in easy manner.

Technical explanation

On-prem IT system may need to use cloud for following examples

• • Need to use Machine learning cloud offering

  • Enable multi site deployment

  • Enforce IT policy using cloud sign-in technologies

Below diagram shows more use-cases

Technicalities for hybrid cloud offering

• • On-prem and cloud Kubernetes uses same code-bases

  • For On-prem, user can setup load balancer of his/her choice

  • Communication between cloud and on-prem is via network channel. These channels can be VPN, leased lines or dedicated channel.

Anthos case study

• • It has admin cluster and user clusters.

  • Admin cluster is a control plane for all user clusters

    • Admin cluster manages user clusters

  • Admin control plane

    • Anthos config manager handles GKE

  • Anthos provides subscription based payment
