There are around 12 Amazon Go / Amazon Fresh in the metro Chicago area. Unless all employees are part-time employees (and assuming around 10-ish employees per store), I seriously wonder how they got around Illinois WARN requirements [1] requiring 60 days advance notice of the closures.
It has at least two (2) ecommerce functions (more if you count B2B Classic / CloudCraze)
1. Salesforce Commerce Cloud B2C - 2016 Demandware acquisition, somewhere in the spectrum of PaaS to SaaS, separate offering compared to the rest of the Salesforce platform. Customizations are done in ISML (JSP/JSTL/JSF-like) and an ECMAScript-like language in modern implementations (not going to cover SiteGenesis, Pipelines, and SiteGenesis Controllers for you old folks here). APIs are provided by the legacy OCAPI layer, and SCAPI layer, which has a thin Mulesoft API layer on top
2. Salesforce Commerce Cloud B2B/D2C - Salesforce-native platform (e.g. native Salesforce objects). Customizations done via Lightning (front-end) and Apex (Java-like language). More-or-less fully integrated into the Salesforce platform. More or less fully SaaS.
Demandware (and subsequently, SFCC) was one of the first ecommerce platforms to pioneer licensing a commerce platform based on revenue sharing (given the SaaS-like model), as opposed to legacy self-hosted platforms (ATG, Hybris, IBM WebSphere) which initially focused on licensing per seats or CPU.
Unpopular opinion: Tab management in browsers originally addressed the shortcomings of OS window management (see Windows XP and IE6, and the original Google Chrome tiling capability replicated into Windows 10/11 OS window management.
Adobe attempted an acquisition of Hybris Software, a Java-based e-commerce platform back in 2013 (see first link). This would have meshed well with their Adobe Experience Manager, their CMS solution (an integration already existed, and was also based on Java/Spring). SAP offered Hybris the opportunity to operate independently for two years, and Hybris was acquired by SAP.
What is surprising is how AEM and Magento will integrate, considering that AEM is a Java/Maven based CMS and Magento is PHP.
