Tetrate launches Industry-first exam for Certified Istio Administrator

Enterprises are increasing their investments in digital transformation and in hiring the right talent to accelerate the journey. According to the 2020 open source jobs report from Linux Foundation, 52% of hiring managers are more likely to hire someone with a certification, up from 47% two years ago. Not so surprisingly, 93% of hiring managers report difficulty finding sufficient talent. Tetrate today announced the public availability of its exam for Certified Istio Administrator by Tetrate (CIAT) that evaluates skill, knowledge, and ability to perform Istio service mesh installation and configuration as well as configure traffic management, resilience and fault injection, and use security features of the Istio service mesh.
