with what IT has
become, and

Serverless Computing Emphasis is now
moving towards “Serviceful Serverless”

https://www.infoq.com/articles/serverless-sea-change
This is a shift away from just
coding Functions (FaaS),
towards using third-party APIs for
Back-end functionality (BaaS) as
much as possible . Here’s why:
1. Using Functions like a glue
between Back-end services
2. requires less Back-end code.
3. Less code = less Complexity
and less Technical Debt.

HBC Tech drives the digital retail/e-commerce and digital customer experience
across all HBC retail banners, including Hudson’s Bay, Lord & Taylor, Saks Fifth
Avenue and Saks OFF 5TH. While it’s clear that the future of retail will rely heavily
on new digital and online innovation, we believe that this best model is an omni-
channel approach to succeed in the coming years. With millions of customers, both
online and in stores, HBC is positioned at the center of this reinvention.
A recent survey of HBC Tech employees about HBC culture revealed the three
most common attributes were “fast-paced,” “team-oriented” and “growth.”
FAST-PACED – Our Associates are constantly tackling new problems and
challenges that result from working in an industry that is continuously evolving.
TEAM-ORIENTED – Our Associates work on small, cross-functional teams with a
high level of autonomy and ownership. Projects are run in an agile environment.
We keep meetings to a minimum so people can focus on getting work done.
GROWTH – Our Associates are encouraged to use 20% of their time for learning
new technologies. HBC Tech also has a strong history of developing our
employees and opening new doors for them to grow their careers.
