In the previous post in this series, we covered why Virtual Machine (VM) Live Migration in Kubernetes is difficult: a VM’s IP is its identity, and the “new” VM on the destination node has to come up with the same IP, this something that Kubernetes is not known for, and on top of that, traffic has to switch over only after network security policies are in place.

Kubernetes is built for containers, and it’s been doing that since it used to run docker as an engine for its containers. But what if you want to add VMs to the mix? After all, containers are ephemeral and don’t require fixed IPs as they shift the identity toward labels, but VMs on the other hand are tied to IP addresses and in some cases MAC addresses. This brings us to this blog about VM migration and IP preservation.

There’s a question we hear constantly from platform and engineering leaders right now, “which agent SDK should we standardize on for our Kubernetes clusters?” The honest answer is that the question is slightly wrong, and the rest of this post explains why. But it’s a fair question, so let’s compare the contenders first.

We launched Lynx this week. Instead of restating the pitch, I want to explain how it’s built and why we made the architectural choices we did. If you run Kubernetes and you’re starting to put AI agents on it, this is roughly the system you’d end up designing yourself.

For a decade, one idea has guided everything we’ve built at Tigera: How do you secure a dynamic system with a lot of moving parts that is changing rapidly, with a programmatic approach? Calico has applied that idea for Global 2000 companies running the largest Kubernetes platforms in the world, securing tens of millions of mission-critical transactions every day. Today I’m excited to announce the next chapter of that work: Lynx, a unified control plane for Kubernetes-native AI agents.

You know every service in your cluster by name. You know which team owns each one, what it talks to, how it scales, where its logs go. The agents are a different story. That’s not a criticism, it’s an observation, and it’s one we keep running into. Every company we talk to is shipping agents of some kind, from scales of 10s to 1000s. Customer service bots that field tier-one tickets. Internal copilots that draft emails and summarise meetings and write the boring half of every PR.

The first post in this series argued that AI agent governance hasn’t kept pace with deployment. The second laid out the five pillars of accountability, and what is required. The third walked through why network policies, API gateways, MCP/A2A protocols, DIY security patterns, and Role-based Access Control (RBAC) each leave critical accountability gaps. So what does good look like? The five pillars define what AI agent accountability requires.

SIG Network introduced Ingress in 2015 as a minimal way to expose HTTP services from a cluster. That simplicity was an advantage at a time when most workloads were HTTP, clusters were single-tenant, and the occasional gap could be papered over with a vendor annotation.

Kubernetes has come a long way since its debut in 2014. It’s gone from running a couple of containerized microservices to orchestrating fleets of production workloads spanning everything from AI agents to full scale VMs running in pods. As Kubernetes adoption grows, and its use cases stretch to cover more ground, managing its increasingly complex networking and security landscape demands operational maturity and a platform that supports it.

In The Five Pillars of AI Agent Accountability: A Diagnostic Framework for Engineering Leaders, we walked through each pillar of AI agent accountability (traceability, authorization provenance, identity and ownership, policy at scale, and human oversight) and argued that most enterprises today sit at Level 0 or Level 1 of the Accountability Maturity Model. The most common reaction we get when we share that framework is some version of: “We’re already covered. We have network policies.

Containers, Microservices, and cloud-based applications have revolutionized the way companies build and deliver products globally. This has also changed the attack surface and requires very different security strategies and tools to avoid exposure to sensitive information and other cyber attacks. Regulatory compliance has also evolved making it ever so important for companies to adapt to this new paradigm.

Join us as we look at the advantages, but also the practical challenges, of applying modern, policy-as-code ("PaC") approaches in a modern cloud-ready enterprise. This talk will show how Morgan Stanley is drawing upon years of experience in its own proprietary implementation of PaC in its approach to embracing today's ideas. We will look at a diverse set of considerations from GitOps as a method to applying PaC in modern software development and deployment to enforcement of best practices and compliance in the Cloud.

Security as an afterthought is no longer an option and must be deeply embedded in the design and implementation of the products that will be running in the cloud. It is increasingly more critical for many security teams to be almost, if not equally, knowledgeable of the emerging and rapidly evolving technology. Join Manish Sampat from Tigera, as explores the topic in detail with Stan Lee from Paypal.

Compliance automation is a commonly overlooked area of Kubernetes observability. The question is: how do you automate compliance to a security framework that isn’t well understood by DevSecOps teams to begin with? This lack of understanding contributes to mismanaged compliance efforts and in a worst-case scenario, audit exposures and organizational risk. This talk will walk through an example of how to 1) map compliance controls to specific Kubernetes technical configuration 2) automate the assessment of those controls 3) visualize the assessment results. DevSecOps teams will better understand how to incorporate compliance automation alongside security automation.

"Companies of various sizes are building their applications on Kubernetes because it provides significant operational benefits like autoscaling, self-healing, extensibility, and declarative deployment style. However, the operational benefits are only a starting point down the path of building a secure and observable platform that enables the continuous delivery of application workloads. This session shows how to build a fully operational platform, leveraging platform-oriented building blocks to address network security and observability.

As more production workloads migrated to the cloud, the need for Intrusion Detection Systems(IDS) grew to meet compliance and security needs. With the number of workloads in each cluster, IDS needs to be efficient to not take up the shared resources. Techniques such as packet inspection and web application firewalls provide a solid defense against threats and by leveraging the cluster's network control pane, we are able to selectively choose vulnerable workloads and provide an easy way to trace back to the origin of the attack.

Kubernetes is being adopted by every major enterprise on the planet for deploying modern, containerized applications. However, containers are highly dynamic and break their existing security models. Tigera provides zero-trust network security and continuous compliance for Kubernetes platforms that enables enterprises to meet their security and compliance requirements.
Tigera’s technology is recognized and trusted as the de facto standard for Kubernetes network security. Our open source software, Tigera Calico, provides production-grade security, and our commercial offerings layer on advanced security capabilities, enterprise controls, and compliance reporting.
Kubernetes Requires a Modern Approach to Security and Compliance:
- Zero-Trust Network Security: With 40% or more of all breaches originating from within the network, you must always have to assume that something has been compromised. Applications running on Kubernetes make heavy use of the network for service to service communication. However, most clusters have been left wide open and are vulnerable to attack. A zero trust approach is the most secure way to lock down your Kubernetes platform.
- Continuous Compliance: Kubernetes is dynamic and constantly changing. Moments after a compliance audit is completed the environment will have changed again. A continuous compliance solution is the only way to prove that your security controls have been implemented properly now and historically.
- Visibility and Traceability: Applications running on Kubernetes Platforms have constantly changing IP addresses and locations that makes it impossible to use traditional flow logs to debug issues and investigate anomalous activity. The only accurate approach is to use Kubernetes labels and workload identity in your netflow logs.
- Multi-cloud and Legacy: Many applications running on Kubernetes will not be greenfield. Applications often need to communicate securely with other systems outside of the cluster, such as on-premises or cloud-based VMs, bare metal servers and databases. To achieve zero trust security for Kubernetes, your security policies must be capable of expanding beyond the cluster.
