SAP Hybris Commerce Integration Package for Retail

I was going through the blog on overall integration landscape of Retail which seems to suffice my requirement in understanding how different dots talk to each other. However when I try to get into more details by clicking link available within below link it is not active. Please provide link or document which will help understand landscape in detail. Thanks for the help
