Linkerd,Fast, secure, and reliable service mesh **Rating:** 4.0/5.0 stars **Reviewed by:** Hamed G. | devops engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** November 05, 2024 **What do you like best about Linkerd?** Lightweight and resource-efficient, ideal for Kubernetes. Automatic mTLS encryption for secure service communication. Instant observability with golden metrics, no extra setup needed. Built-in reliability with automatic retries and timeouts. Kubernetes-native, seamlessly integrated for easy operation. **What do you dislike about Linkerd?** Limited Customization: Linkerd keeps things simple, but that also means fewer advanced options for customizing traffic management compared to some other service meshes. Missing Some Power Features: It doesn’t have all the fancy features like traffic shadowing or complex routing rules that you might find in heavier meshes like Istio. Kubernetes Only: Linkerd is designed purely for Kubernetes, so if you’re running on other platforms or need multi-cloud support, it might not cover all your needs. Smaller Ecosystem: While Linkerd has a great community, it doesn’t have the vast ecosystem and range of plugins you’ll find with bigger meshes like Istio. **What problems is Linkerd solving and how is that benefiting you?** Simplifies secure, reliable communication between microservices in a Kubernetes environment. Provides automatic retries, timeouts, and circuit breaking, enhancing service resilience for business-critical applications. Ensures encrypted, authenticated connections between services with automatic mTLS, supporting strict security requirements. Isolates and manages traffic for multiple teams or business units within a shared Kubernetes cluster. ### 3. Review on Linkerd **Rating:** 4.0/5.0 stars **Reviewed by:** Yousuf N. | Cybersecurity Researcher, Computer & Network Security, Small-Business (50 or fewer emp.) **Reviewed Date:** November 06, 2024 **What do you like best about Linkerd?** It is a lightweightand easy to set up, which works good with kubernetes without slowing things down. It has a security built-in and shows a problem very fast, and it makes easy to manage and fix stuff. **What do you dislike about Linkerd?** It can be limited in features compared to other service meshes. Also it will be difficult for beginners who are new to kubernetes and service meshes. **What problems is Linkerd solving and how is that benefiting you?** It helps by securing data between service with encrypton making it harder for attackers to intercept information. Also it gives quick insights on issues, so that able to respond fast to potential security risks. ### 4. The best product available in the market for service mesh and cross cluster communication **Rating:** 5.0/5.0 stars **Reviewed by:** Sachin A. | Staff devops, Enterprise (> 1000 emp.) **Reviewed Date:** February 27, 2024 **What do you like best about Linkerd?** The ease of setting up and simplicity of the tech stack. It's feature to enable service mirroring in order to provide cross cluster service communication and building the service mesh around the cluster components is a deal breaker. **What do you dislike about Linkerd?** Till version 2.5 it was open source and now it is anounced to be a licensed one. **What problems is Linkerd solving and how is that benefiting you?** It is helping us in mirroring the kubernetes services across the clusters in order to make a cross cluster communication. ### 5. Linkers review **Rating:** 5.0/5.0 stars **Reviewed by:** Hardik S. | ML engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 03, 2023 **What do you like best about Linkerd?** I like how easy it is to install and especially that it is a very light weight service mesh. Compared to other solutions in the industry , it is the most lightweight and have one of the best documentation available **What do you dislike about Linkerd?** I don't particularly dislike anything about it. I have loved working with linkerd and havnt disliked anything. One think is that it sometimes doesn't install for me and i have to reinstall it to work. **What problems is Linkerd solving and how is that benefiting you?** Its providing the very much needed observability in my kubernetes cluster and the applications running inside it. It also let's me configure my own Prometheus and grafana and integrate the same with linkerd installation. ### 6. Simple, Fast, Solid **Rating:** 5.0/5.0 stars **Reviewed by:** Steve G. | Founder & CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** December 05, 2022 **What do you like best about Linkerd?** In the majority of cases, Linkerd can be used with very minimal configuration and provide benefits to a Kubernetes hosted application stack. Some of the best features include elements such as highly effective weighted load-balancing for HTTP and GRPC traffic, and the ability to use security policies to limit which pods can talk to other pods in order to lock down the internals of your cluster. The proxies are very low overhead, especially if you're comparing to an envoy/istio based environment, and having a barely-there footprint means there little to no cost to deploying into most clusters. **What do you dislike about Linkerd?** The multi-cluster experience doesn't handle a few of the scenarios we'd hope for, but this is something that's generally able to be worked around. **What problems is Linkerd solving and how is that benefiting you?** - Inter-application identity and access control - Load balancing of GRPC sessions - Automatic retry of slow requests. ### 7. Linkerd is the easiest Service Mesh you can find **Rating:** 5.0/5.0 stars **Reviewed by:** Eli G. | Director of Platform Engineering, Mid-Market (51-1000 emp.) **Reviewed Date:** December 06, 2022 **What do you like best about Linkerd?** Linkerd is dead simple to use. It is also the fastest (added latency) and the lightest (resource consumption) service mesh. It's great to see how much thought the maintainers put into ensuring "it just works" (especially across releases). **What do you dislike about Linkerd?** It doesn't necessarily have all the features other service meshes have, but releases are frequent, and the community is super involved. But I think most systems don't really need all of the features other service meshes offer. **What problems is Linkerd solving and how is that benefiting you?** First, gRPC load balancing gets a simple solution with Linkerd. On top of that - great visibility over the synchronous communication between services, and monitoring SLOs - latency, success rates and traffic volumes. Lastly, security - encrypted connectivity between pods out of the box. ### 8. The service mesh you can’t afford to not use **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User **Reviewed Date:** December 06, 2022 **What do you like best about Linkerd?** The zero-conf nature with an option to tap into enterprise features like using your own PKI. Also linkerd is super stable and robust and offers great performance **What do you dislike about Linkerd?** Honestly, can't think of anything major. **What problems is Linkerd solving and how is that benefiting you?** Automatic mTLS between all services solves a critical regulatory requirement for us with very little effort. Multi-cluster mesh helps to reduce cloud costs ### 9. Constantly needs restart **Rating:** 1.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** July 31, 2018 **What do you like best about Linkerd?** The system is essentially zero-config for dynamic services and namespaces **What do you dislike about Linkerd?** The pods seem to get into a split brain state very frequently, and we have to perform a rolling restart to bring back stability. It is bad enough now that we have a job perform the restart nightly **Recommendations to others considering Linkerd:** Be ready to evaluate it in your environment compared to other solutions **What problems is Linkerd solving and how is that benefiting you?** It allows us to manage service level routing inside our kubernetes environments ## Linkerd Discussions - [What is Linkerd used for?](https://www.g2.com/discussions/what-is-linkerd-used-for) - [View Linkerd pricing details and edition comparison](https://www.g2.com/products/linkerd/reviews?section=pricing&secure%5Bexpires_at%5D=2026-06-05+23%3A52%3A34+-0500&secure%5Bsession_id%5D=9395cc78-fcf1-4005-a687-43095f65d85f&secure%5Btoken%5D=e54ba4d415cad1eeb0e2097cb44380c3d95a860cefc76f5299b1e10db3f28031&format=llm_user) ## Linkerd Features **Functionality** - Supported Protocols - Container Orchestration - Extensibility - Monitoring **Cloud Visibility** - Data Discovery - Cloud Registry - Cloud Gap Analytics **Networking** - Networking - Load Balancing - Traffic Filtering - Service Discovery **Security** - Data Security - Data loss Prevention - Security Auditing **Protection** - Policy Management - Secure Communications **Identity** - SSO - Governance - User Analytics ## Top Linkerd Alternatives - [Istio](https://www.g2.com/products/istio/reviews) - 4.2/5.0 (18 reviews) - [AWS App Mesh](https://www.g2.com/products/aws-app-mesh/reviews) - 4.3/5.0 (12 reviews) - [HashiCorp Consul](https://www.g2.com/products/hashicorp-consul/reviews) - 4.3/5.0 (20 reviews)
