End of the app serv­er and the ESB

Another great in­de­pen­dent ar­ti­cle on how the app serv­er is dis­ap­pear­ing, with the ESB go­ing along:

Mi­cro ser­vices on light weight con­tain­ers like Dock­er or maybe Drop­wiz­ard or Spring Boot are the end of the ap­pli­ca­tion serv­er that served us so well last decade. If you can scale your ap­pli­ca­tion by start­ing a new process on a fresh VM you don’t need com­plex soft­ware to share re­sources. That means you don’t re­al­ly need a lot of in­fra­struc­ture. You can de­ploy small com­po­nents with neg­li­gi­ble over­head. Key-val­ue data stores al­low you to re­lax con­straints on data that where im­posed by re­la­tion­al data­bas­es. A ser­vice might sup­port two ver­sions of an in­ter­face at the same time. Com­bined with REST, a DNS and a load bal­ancer this is the end of ESBs.
