Kubernetes as a Service (K8saaS)
PaaS Cloud provides Kubernetes as a multi-tenant, fully managed service. This means that instead of deploying and maintaining your own Kubernetes cluster on virtual machines, you receive a ready-to-use Kubernetes environment with self-service scaling, automated updates, and built-in tooling.
Compared to KOST
Teams that previously used KOST or similar self-managed infrastructure often find PaaS Cloud more convenient for the following reasons:
| Area | KOST (Self-Managed) | PaaS Cloud (Managed) |
|---|---|---|
| Cluster Startup | Manual provisioning of VMs and cluster setup | Cluster is ready in minutes via the platform |
| Scaling | Requires infrastructure change requests or manual work | Self-service scaling through dashboard or API |
| Lifecycle & Maintenance | Users patch and upgrade nodes and cluster components | Lifecycle managed by the platform team |
| Node Management | Full responsibility for VM and OS management | No need to manage underlying Kubernetes nodes |
Marketplace Out-of-the-Box Services
One of the main strengths of PaaS Cloud is its application marketplace. You can deploy production-grade infrastructure components directly from the dashboard without manually configuring containers or custom charts.
Databases
- PostgreSQL — Managed relational database
- MariaDB — Open-source MySQL-compatible database
- ClickHouse — Column-oriented DBMS for analytics
- FoundationDB — Distributed transactional key-value store
- MongoDB — Document-oriented NoSQL database
- Redis — In-memory data store and cache
- Qdrant — Vector similarity search engine
Messaging & Streaming
- Kafka — Distributed event streaming platform
- RabbitMQ — Reliable message broker
- NATS — Lightweight messaging system
Infrastructure & Tooling
- Harbor — Container image registry with scanning and RBAC
- OpenBAO — Secrets management and data protection
- Load Balancers — TCP and HTTP load balancing
- Virtual Machines — Traditional VMs running inside the platform
- Grafana-Based Monitoring — Dashboards, logs, and alerting for your workloads
Extending the Marketplace
Adding new infrastructure stacks to the marketplace is a team-driven process:
- A user or team identifies a new application or service that would benefit the community.
- The user can contribute requirements, documentation, or Helm chart drafts.
- The cloud team reviews, approves, and deploys the new service into the marketplace.
- Once published, all eligible tenants can deploy the new service just like any other managed application.
This ensures that the catalog remains high-quality, secure, and well-supported.
Summary
PaaS Cloud is ideal for teams that want:
- Managed Kubernetes without operational overhead.
- Fast self-service scaling.
- Quick access to databases, registries, and messaging via the marketplace.
- A clear lifecycle with platform-managed maintenance.
Note
If you need full control of VMs, network topology, and custom images, consider the IaaS Cloud instead.
