@nikhilch9999 Hi there, you'll need to sign the CLA before we can review your PR– see here: https://api.easycla.lfx.linuxfoundation.org/v2/repository-provider/github/sign/18706487/51478266/50911/#/?version=2. Also, there's no information that you've given on why you've removed this certain sentence from the architecture concepts documentation, so please let us know why you've suggested we do so – I don't think this should be removed, but am open to other opinions.

Thanks for contributing to Kubernetes!
