How does PaaS security handle multi-tenancy risks in a shared infrastructure environment?

All answers to this question.

Modern PaaS providers use robust "Hypervisor-level isolation" or "Container Sandboxing" to ensure your processes never interact with others. For example, platforms using gVisor or Firecracker microVMs provide a very thin but strong security boundary. For data, look for "Encryption at Rest" and "Encryption in Transit" as standard features where you can manage your own keys (BYOK). If you are in healthcare or fintech, you must ensure the provider is HIPAA, PCI-DSS, and SOC2 Type II compliant. They should also offer a "Private Link" or "VPC Peering" to keep your traffic off the public internet entirely.

Is it possible to get a "Dedicated Instance" on a PaaS if our security team refuses to share the underlying hardware with any other tenants?

• Yes, Michael, most top-tier providers like Azure or AWS offer "Isolated" tiers or "Dedicated Hosts." You still get the PaaS management benefits—like automated patching and OS updates—but the physical hardware is reserved solely for your organization. It's much more expensive, often triple the price, but it completely removes the multi-tenancy risk and satisfies strict regulatory requirements for hardware isolation.

Security in PaaS is a shared responsibility model. The provider secures the platform, but you are still responsible for your application code and API security.

• Great point, Laura. Many people forget that a secure platform won't save you from a SQL injection or a poorly configured IAM policy in your own application code!
