Support for Kubernetes deployments, elastic search indices migration and terraform changes (AWS)

I am looking for long term support for kubernetes, EKS indices migration and terraform related work on AWS, the urgent issue that needs to be resolved is configuration/routing issues between istio proxy and containers where the access is denied 503 UF errors (upstream connection failure for inbound/outbound calls).
And there is other long term work scheduled related to Elastic search and terraform related.
