What is a Stemcell?

A Stemcell is a OS image wrapped with IaaS specific packaging. Amongst other tools, it always contains a BOSH Agent (like a Chef client) running on the VM to which the stemcell is deployed to and listens for instructions from the BOSH Director.

@Configuration

    @Bean
    public FirstClass firstClass() {
        return new FirstClass();
    }
