2025 was the year that RISC-V readiness gave way to RISC-V adoption. It’s been quite a journey.

Engineering organizations are waking up to something that used to be optional: measurement. Not vanity dashboards. Not a quarterly “engineering metrics review” that no one prepares for. Real measurement that connects delivery speed, quality, and reliability to business outcomes and decision-making.

The average cost of a security breach reached nearly $4.4 million in 2025, according to the publication Cost of Data Breach Report. To proactively address this substantial financial and security risk, Infobip, a global cloud communications platform, used HAProxy Enterprise to implement a security and uptime framework that is both highly modular and highly performant.
