👉 What is Identity-Native Infrastructure Access?
What the largest tech companies like Google and Facebook have discovered as they have grown their infrastructure is that traditional access control systems do not scale. Not only does the risk of a breach increase with each secret, but forcing developers to juggle hundreds of credentials to do their jobs limits productivity and encourages insecure workarounds.

The largest companies in the world have discovered that identity-based access is the way out of the dilemma.

This O'Reilly book will explain the concept of identity-based infrastructure access, and how it differs from more common older approaches based on secrets.

You don’t need orm in Go   ✅
Object-relational mapping (ORM) is a technique (a.k.a. design pattern) of accessing a relational database from an object-oriented language.

There are multiple implementations of ORM in almost every language; for example: Hibernate for Java, ActiveRecord for Ruby on Rails, Doctrine for PHP, and SQLAlchemy for Python.

Of course, there are also libraries for Go like gorm or xorm. These libraries are huge and they use a lot reflection package and one of the Go proverbs is reflection is never clear .
