In “Microservices: How ‘Cloud Native’ Are Network Vendors Today?”, we looked at some of the unanswered questions around microservices. This blog takes the cloud native discussion a little further by discussing the issues around ‘stateless operation.’ Continue reading “Three Different Approaches to VNF Data Management Could Spell Trouble Ahead”
