Pod Security Standards (PSS) are a low‑friction way to harden clusters by default. With Pod Security Admission (PSA), you can enforce least‑privilege at the namespace level and prevent risky pods from ever being created. It’s simple, auditable, and fits cleanly into GitOps. Improving your security posture Implementing Pod Security Standards is crucial as it helps reduce the blast radius by blocking privilege escalation and host-level access. It allows teams to catch misconfigurations early during the admission phase rather than after deployments, ensuring issues are addressed promptly.

Introducing Service Accounts in Thalassa Cloud

Service accounts are non‑human identities designed for automated systems, applications, and integrations. In Thalassa Cloud, they are organisation‑level principals with their own roles and one or more access credentials. Use them for CI/CD pipelines, controllers, monitoring, provisioning, or any workload that needs programmatic access. Service accounts separate machine access from human users, enabling least‑privilege policies, independent credential rotation, and clean audit trails. Each service account can hold multiple credentials, so you can rotate keys with zero downtime.

Block Volume Snapshots and Snapshot Policies

We recently introduced Block Volume Snapshots and Snapshot Policies in Thalassa Cloud. This adds simple, reliable data protection and recovery workflows for your IaaS workloads without disrupting running applications. Snapshots is one of the core building blocks for operating modern cloud services in a safe manner. I.g. quickly restoring or cloning a database, or for additional back up strategies. What are Block Volume Snapshots? Block Volume Snapshots are point‑in‑time, incremental copies of a Block Volume.

VPC‑Only Access for Kubernetes Clusters

We’ve added support for VPC‑only access to Kubernetes control planes. When enabled, the cluster’s public API endpoint is disabled and the Kubernetes API is reachable only from within your Virtual Private Cloud. This helps teams meet stricter security and compliance requirements without sacrificing operational access. VPC-only access is valuable for DevOps teams because it boosts security by removing the internet-facing API endpoint, which reduces the attack surface. It also makes network rules and identity limits clearer by using your VPC as the boundary.

Beyond IaaS: Why European Cloud Providers Must Build More Than Basic Infrastructure

European businesses need more than just basic IaaS like virtual machines and storage. These basics are important, but they don’t meet the complex needs of modern applications. To compete globally and keep data within Europe, businesses require a platform with advanced services. Thalassa Cloud goes beyond traditional IaaS by offering a platform with advanced services for modern applications. It provides European businesses with the tools needed for cloud-native applications, ensuring both advanced features and compliance.

Building KMS and Secret Manager for the Dutch Cloud

We’re excited to announce that we’re building Key Management Service (KMS) and Secret Manager for Thalassa Cloud. These security services will provide the foundation for secure application development on our Dutch public cloud platform. Why We’re Building These Services Modern cloud-native applications need more than just basic infrastructure. They require robust security & Encryption services that integrate seamlessly with your development workflow. While we already offer IaaS, Kubernetes as a Service and databases, we’re expanding our platform to include the fine graind encryption services.
