### AI overview

Klarna describes Cloud Inventory, an ecosystem of services for collecting, normalizing, mapping, and serving information about ICT assets across its cloud infrastructure. The article explains how it supports configuration management through automated controls and reports faster control rollout and large-scale infrastructure optimization work.

### Source excerpt

A long time ago, as a punishment for his crimes, Hades, the king of the underworld, made Sisyphus roll a huge enchanted boulder endlessly up a steep hill. Since then, many tech companies have learned to do that at scale by the hardships of cloud configuration management. Consider an Engineer who wants to ensure that the data that moves through their system is encrypted along the way. This is a noble goal, and to achieve it they must identify every classic load balancer in their AWS environment to replace it with an application load balancer that enforces encryption in transit. Now imagine doing that at the scale of a company like Klarna, where teams collectively own more than a thousand AWS accounts? Add to this a multitude of other configuration challenges -- databases that have not been deployed in a multi-availability zone set-up, missing Cloudwatch logs, expired digital certificates, systems running on unsupported framework versions -- the list is endless. Identifying and rectifying violating cloud assets often feels like an endless game of whack-a-mole played blindfolded. This is the steep price tech companies pay to operate their systems securely and confidently, day by day. Klarna Engineering Platform (KEP) has been on a mission to facilitate configuration management for Klarna Engineers. After a few iterations we have built an ecosystem of Klarna services designed to collect, normalize, map, and serve data on ICT assets within Klarna's cloud infrastructure. We call this system Cloud Inventory. Over the last few months Klarna has: Rolled out over 100 automated controls enhancing every aspect of our configuration management (security, governance, and operational excellence), each control aimed to help system owners to identify and fix violations quickly. Reduced the lead time of rolling out a control from several weeks to a matter of minutes And as a result, successfully completed several large-scale cloud infrastructure optimization projects, such as a company-
