Do you have an idea for a startup and don't want to pay for scaling it up? Forget about bandwidth problems, servers to install and pay for, with the power of IPFS and the blockchain.
In this talk, we will explore how to build an HTML5 DAPP (distributed application) with EmbarkJS, and figure out how to rethink servers, storage, messaging, data and payments in a distributed and decentralised way with the help of Ethereum's smart contracts and IPFS distributed storage.

  17. 17. 17 (DE)CENTRALISED 
 SERVLESS COMPUTING DISTRIBUTED
 SERVLESS COMPUTING you don’t have to manage servers or services, 
 neither to worry how to scale or allocate them… 
 as long are you able to pay 
 or to cope with the provider’s rules you don’t have to manage servers or services, 
 neither to worry how to scale or allocate them… 
 but you can help build the network
 and been rewarded for it Trust is upon the the provider Trust is upon the network Resilience and scalability 
 through (de)centralised
 clustering, sharding, zoning… Resilience and scalability 
 through distributed networks Alessandro Confetti - November 11th 2017 – Codemotion, Milan
