Too Long; Didn't Read
According to 2019 Forrester report, 49% of companies are using or planning to use serverless architecture in the next 12 months. Serverless is not fewer servers or no servers; it does not relate to or involve running code without servers. The main selling point of serverless is ‘focus on what matters’.Serverless is event-driven, reacting only when something happens. It is not just about containers and Lambdas; package managers like Artifactory play a vital part here as well.
