Secure mesh has strengthened zero‑trust traffic and improves compliance visibility
The most valuable features for us are automatic mTLS with a strong identity model, which is critical for a fintech environment where encrypted east-west traffic is non-negotiable. Authorization policies are essential because the ability to explicitly define and enforce which services can call each other has been extremely powerful from a compliance and zero-trust standpoint. Operational simplicity is another valuable feature, as Linkerd’s lightweight design and straightforward control plane reduce cognitive and operational load compared to other meshes. Lastly, having enterprise support and stability through a supported enterprise build with security patches and predictable releases gives us confidence in production.

Enhanced microservice security and advanced traffic management and good authentification
When our developers are building the microservices, instead of imposing additional burdens or additional thinking on them, especially as part of network features such as traffic management, security, or observability, we deploy something from the infrastructure side, so developers need only focus…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Buoyant Enterprise provides superb support, and the cost savings from HAZL make the license almost cost neutral."
"Buoyant Enterprise for Linkerd has made it simple for us to deploy and operate Linkerd across our clusters."
"Buoyant Enterprise for Linkerd significantly improved our security posture by enforcing mTLS across all services with minimal operational complexity."
"Security and compliance have been enhanced with Zero Trust featuring mTLS, workload identity, and end-to-end encryption without code changes."
"The tool's mutual TLS stands out. It provides secure communication between services within the cluster. Additionally, Istio offers built-in telemetry and tracing with tools like Jaeger, which aids monitoring and troubleshooting."
"Istio makes all that much easier - traffic splits, percentage traffic splits, doing some sort of chaos testing to see how it works."
"The most valuable features of Istio are the traffic management and the Sidecar they inject, which greatly helps secure the application."
"The load balancing, service application, and monitoring of the life of the service are valuable features. We use it for authentication of call services, load balancing the calls among the service providers on service instances, and monitoring the health of the services."
"Istio's best feature is that it's easy to use."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
"We use Istio for Service Discovery and routing traffic."
"Istio can save you time in terms of network troubleshooting."
 

Cons

"I hope HAZL load bands can be tuned more easily or even automatically."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"If you're a beginner in infrastructure management and networking, learning Istio might pose some challenges. However, if you have some knowledge of networking or service meshes, you should find it manageable. Istio's website offers documentation to guide you through learning."
"Based on my experience, the solution could be improved. They could simplify the learning process so that users can understand how its features work together, especially with components like Kibana. Learning about the different components is necessary. For instance, you need to understand the traffic flow, potential bottlenecks, and the architecture within Istio."
"Istio needs to be more mature and user-friendly."
"For our use case that we applied it to, there were graph queues and the calls that were coming in. There were the things that we couldn't apply at the time, but it kind of worked."
"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."
"It would be beneficial if Istio offered paid support options, similar to AWS's enterprise support, to quickly resolve issues that might affect production."
"Reducing the latency between the control plane and the data plane would be beneficial."
