Tigera Introduces Lightweight Service Mesh for Secure Microservices Communication

Tigera, the creator of Project Calico, is introducing Calico Cluster Mesh, delivering on its approach to secure microservices communication.

According to the company, Calico Cluster Mesh delivers the benefits of a service mesh without the added complexity and latency of a traditional service mesh solution.

With Tigera’s differentiated approach, Calico provides the capabilities to address the security and observability challenges organizations face without the overhead of a bespoke service mesh solution. 

“Calico Cluster Mesh empowers today’s IT and security teams with the capabilities they need to achieve their goals, without adding complexities or costs,” said Amit Gupta, chief product officer, Tigera. “Tigera’s lightweight service mesh approach, delivered through Calico Cluster Mesh, reinforces our dedication to providing simple, scalable, cost-effective solutions. We’re proud of the work we’ve already accomplished, helping a major financial organization innovate while upholding compliance and security regulations and mandates.”

Calico enables a single-pane-of-glass unified control to address the three most popular service mesh use cases—security, observability, and control—with an operationally simpler approach, avoiding the complexities associated with deploying a separate, standalone service mesh.

With Calico, users can easily achieve full-stack observability and security, deploy highly performant encryption, and tightly integrate with existing security infrastructure like firewalls, according to the company.

Calico Cluster Mesh provides users with the following capabilities:

  • Seamless service-to-service connectivity across clusters – Calico Cluster Mesh hides network complexity and simplifies service connectivity for developers. The lightweight service mesh provides robust workload connectivity that works with flat, cloud, or hybrid networks, and eliminates network changes with a choice of TOR or Overlay VXLan networking. Additionally, cross-cluster networking is simplified with DNS connectivity.
  • Service discovery and security – Calico Cluster Mesh enables both the discovery of remote services with federated service, and interaction with remote services in a multi-cluster environment. The lightweight service mesh enforces consistent network security controls on local and remote services.
  • Observability and troubleshooting – With Calico Cluster Mesh, users can visualize workload communication and application dependencies across clusters. They can troubleshoot service-to-service communication more quickly, while also identifying security gaps and enforcing network security controls.
  • Multi-cluster security controls – Calico Cluster Mesh includes a single management plane to manage security controls for multiple clusters. The lightweight service mesh provides centralized observability and troubleshooting across clusters.
