HashiCorp Consul offers more streamlined and user-friendly features.
Room for Improvement: Users noted Istio's steep learning curve and complexity in setup and configuration as areas needing improvement. HashiCorp Consul requires enhancements in its multi-data center capabilities and better documentation. Istio's areas for improvement are tied to its complexity, while HashiCorp Consul focuses on specific functional enhancements.
Ease of Deployment and Customer Service: Istio has a more challenging deployment process and requires significant expertise, according to user reviews. Customer service is responsive but can be overwhelmed. HashiCorp Consul receives positive feedback for its easy deployment and high-quality customer service. Users particularly value HashiCorp Consul's supportive documentation.
Pricing and ROI: Istio's setup costs are higher due to the complexity and need for skilled personnel, but it delivers substantial ROI in large and complex environments. HashiCorp Consul's lower setup costs and faster time to value make it an attractive option. Users report quicker ROI with Consul, appreciating its cost-effectiveness.
I have seen a return on investment as time is saved because of those features.
At first, I didn't see significant savings, but in the end, I realized that I didn't need as many tools since Istio already contains many aspects and features, which saved me a lot of time and probably money.
Using Istio in a banking environment provides excellent value by ensuring secure microservice communication and minimizing performance issues through traceability and other observability features.
Responses are often received within 24 hours, which is fair given the free nature of the service.
HashiCorp Consul is scaling great; I think we are seeing exactly what we need for communication.
Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance.
I use AWS EKS with a cluster autoscaler, enabling automatic scaling based on load.
The architecture, configuration, and resource management can impact stability.
I rate the stability of Istio as an eight or nine out of ten.
Istio has been stable in my experience.
I think the documentation sometimes can be better; it needs to make it easier for our developers to understand how to interact with it.
HashiCorp Consul can provide some required management such as managing a cluster, certificate, or networking.
They can provide user IAM features, such as identity and access management, allowing more granular access control for DevOps engineers and developers.
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.
Integration with observability tools like Prometheus, Grafana, and Elasticsearch incurs additional costs.
Out of those features, the key-value store and health checking have made the biggest difference for my team because we mostly use the key-value store, and that key-value store has really impacted our product and our use case for storing and keeping our secrets and configurations there.
Integration of security scanning tools with HashiCorp ensures vulnerability detection and pipeline protection, offering observability into whether the code is ready for deployment and tracking historical metrics.
We are looking for our applications to communicate more easily without having to define IP addresses and other configuration details.
Istio provides excellent documentation and support, allowing for easy troubleshooting.
The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable.
