+Splunk has been a heavy Istio user for the last 3 years, using it as their baseline for network ingress, policy and authentication.
+
+In [this talk from IstioCon 2022](https://events.istio.io/istiocon-2022/sessions/istio-at-splunk/), Bernard van de Walle explores how Splunk manages, installs and operationalizes Istio at scale on more than 40 clusters across multiple regions and providers. He describes their journey in detail, including the trade-offs that were taken into account before jumping into Istio, as well as the lessons learned over time. He also goes into detail on how Splunk's internal users are using Istio and how they are supported.

+WP Engine has adopted Istio as a core technology for its internal microservices platform over the past 2 years, enabling internal engineers to ship products and features quickly and reliably. The platform has a multi-tenant architecture and uses various technologies such as containerized builds, GitOps deployments, and automated policy enforcement all in conjunction with Istio to meet their business and technical goals.
+
+The decision to implement an internal platform with Istio has revolutionized the way WP Engine ships software by minimizing the common cross-cutting concerns engineers have to consider in building their applications. Implementing this platform has improved consistency between services, reduced operational overhead across the organization, and enhanced the security and observability of this runtime environments.
+
+In [this talk from IstioCon 2022](https://events.istio.io/istiocon-2022/sessions/how-wp-engine-uses-istio/), Rahul Dhir discusses WP Engine’s journey building a platform with Istio and how its benefits are moving their business forward.

+ZOZOTOWN was launched in Dec 2004 and is currently one of the biggest fashion E-commerce companies in Japan. It was implemented as monoliths, and over the last 3 years a modernization project achieved gradual migration to a Kubernetes-based microservice architecture. ZOZO adopted Istio as a key enabler for the new ZOZOTOWN platform
+
+In [this talk from IstioCon 2022](https://events.istio.io/istiocon-2022/sessions/accelerating-zozotown-modernization/), Yoichi Kawasaki discusses ZOZO’s gradual migration strategy, how they integrated Istio into a platform with an existing in-house API Gateway, their zero-downtime migration, and how further Istio usage is planned to achieve a more sophisticated DevOps experience.
