I recently worked with a financial services client who required Mutual Transport Layer Service (mTLS) communication across Google Kubernetes Engine (GKE) clusters using separated Istio Meshes. We deployed client-side services in one GKE cluster and the application-side services in the second GKE cluster. Establishing mTLS within one mesh-even across multiple GKE clusters-is easy, but I […]

For example, when creating an ingress rule, you will see new terms such as Tag and Service Account along with the more traditional source IP range. Additionally, you need to specify a target Service Account or Tag instead of the traditional destination address.

Sometimes a client needs to restrict access to Google Cloud Platform (GCP) resources to a specified IP range (also referred to as a trust-list). Trust-listing can be useful for various scenarios, such as limiting GCP access to users on a corporate network or giving auditors access to a requested GCP resource. SADA recommends using Access

Recently we encountered network connectivity challenges between Google Cloud Platform (GCP) resources while working on an enterprise customer migration to GCP. Specifically, users could not connect to cluster services like Google Kubernetes Engine (GKE) and Cloud-SQL running in a peered Virtual Private Cloud (VPC). Utilizing public IP addresses is an option, but that solution did

Introduction If you have been using Kubernetes for a while, you probably know that Kubernetes does not offer any built-in mechanism for defining and managing users. This means that Kubernetes does not store any reference to users or groups to which they belong in its object store ETCD. This allows admins to integrate their organization
