Edge computing as an evolution of cloud computing brings application hosting from centralized data centers down to the network edge, closer to consumers and the data generated by applications. It is acknowledged as one of the key pillars for meeting the demanding 5G Key Performance Indicators, especially as far as low latency and bandwidth efficiency are concerned. Moreover edge computing also plays an essential role in the transformation of the telecommunications business, where telecommunications networks are turning into versatile service platforms for industry and other specific customer segments. ETSI ISG MEC is the home of technical standards for edge computing. The group has already published a set of specifications and reports to offer fully standardized solutions to support IoT applications in distributed cloud. The emphasis of this talk is the MEC features in support of IoT use cases and requirements, as well as the MEC integration with 5G system and the MEC expansion to edge federation.
