In 2012, Amazon opened its first Italian office and its first Italian point of presence (PoP) based in Milan. This includes system integration (SI) and independent software vendor (ISV) partners who have built cloud practices and innovative technology solutions using AWS. Since then, AWS has added another PoP in Palermo in 2017.

The growth in demand for software has consistently outpaced the growth in the supply of software developers. Each major expansion in software development - automation (60s), productivity (80s), internet (90s), mobile (00s) - has been additive to the total stock of software in the world. It's worth looking at why.
