Spring batch: infrastructure

Question

I am reading Spring user guide. I came across below statement. I confused by statement "let the framework take care of infrastructure". I mean infrastructure means any Hardware..Nw in Spring Batch is framework, where does infrastructure came in picture

Batch developers use the Spring programming model: concentrate on business logic; let the framework take care of infrastructure

Please help me in understanding/

If you will read the complete documentation, you will get:

Figure: Spring Batch Layered Architecture

This layered architecture highlights three major high level components: Application, Core, and Infrastructure. The application contains all batch jobs and custom code written by developers using Spring Batch. The Batch Core contains the core runtime classes necessary to launch and control a batch job. It includes things such as a JobLauncher, Job, and Step implementations. Both Application and Core are built on top of a common infrastructure. This infrastructure contains common readers and writers, and services such as the RetryTemplate, which are used both by application developers(ItemReader and ItemWriter) and the core framework itself.
