New cloud architectures: Private clouds and data lakes

After a period of ‘all-in’ public-cloud enthusiasm, many telcos are pulling certain workloads back on-prem or into operator-hosted private clouds. Surveys show a majority of companies are implementing private clouds, citing cost savings and tighter control of sensitive data. Modern private clouds now look and feel like public clouds: Containerised, API-first, pay-as-you-grow, but without the egress fees. For network operators this means lower network-function operating expenditure and a chance to offer sovereign cloud capacity to enterprise customers. This panel discusses architectural blueprints, data-lake patterns and the operational talent mix required to run them.
