The evolution of DevOps automation Since the concept of DevOps emerged around 2007 and 2008 in response to pain points with Agile development, DevOps automation has been continuously evolving. The system analyzes performance patterns and historical data to uncover the specific software bug or resource constraint causing the issue.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

March 26, 2008 doesn't have any delicious desserts associated with it, but that's the day when we launched Availability Zones for Amazon EC2. Zones impact how we build, deploy, and operate software, as well as how we enforce security controls between our largest systems. One is that the latency within a zone is incredibly fast.

The Morning Paper

The storage backend is the software module directly managing the storage device attached to physical machines. In 2008, with the emergence of Btrfs, a new implementation was built taking advantage of Btrfs’ transactions, deduplication, checksums, and compression. RADOS has been through a number of iterations in the preceding decade+.
