Istio has been around for a while and, yeah, it’s pretty well-established. It does a lot, traffic management, security, observability, but honestly, it can sometimes feel like it’s a bit too much. As microservices setups get more complicated, folks start to think, “Is there a simpler way to do this?” The constant tweaking, configuring, and maintaining can start to wear on you, and you might wonder if there’s something a little less heavy-handed out there.
There are other tools that might make things easier. Some focus on simplifying the setup, others are all about boosting security or handling scalability without all the fuss. They might not be as mainstream as Istio, but they bring something fresh to the table. Let’s take a look at a few that might be worth considering.
1. AppFirst
Managing cloud infrastructure can be a pain. With Istio, it sometimes feels like you’re constantly adjusting configurations and dealing with sidecars. AppFirst aims to take that burden off your shoulders by automating a lot of the setup. It handles provisioning secure infrastructure across cloud platforms like AWS, Azure, and GCP, so you don’t have to constantly dive into configurations.
The beauty of this is that it lets you focus more on your actual app rather than fighting with cloud setup. Plus, with built-in monitoring, logging, and alerting, everything stays in check without needing a bunch of different tools.
Faits marquants :
- No separate infrastructure team required.
- Built-in monitoring and alerting.
- Flexible deployment (SaaS or self-hosted).
- Transparent cost tracking.
- Works across different cloud environments.
Services :
- Secure infrastructure provisioning.
- Audits infrastructure changes.
- Performance optimization tools.

Consul takes a different approach. It’s designed to make communication between services smoother and more secure. Whether you’re working in the cloud or on-prem, Consul helps you discover services and automate network tasks like load balancing and firewall management. It’s a good fit if you need to scale things up while keeping everything secure and working across different environments.
What stands out is that Consul automates a lot of those network tasks that would otherwise take up tons of your time. It’s particularly helpful when you need to secure communication across different data centers.
Faits marquants :

8. Greymatter.io
Greymatter.io treats service mesh as part of the security and networking fabric, not a separate bolt-on. Service traffic, identity, and policy all live in the same control layer, which makes more sense once systems stretch across clouds, data centers, and the edge.
The focus is on consistency. Instead of tuning things cluster by cluster, control and policy are handled centrally, with automation doing most of the heavy lifting. Observability and auditing aren’t extras, they’re built in, which fits environments where tracking change and enforcing rules actually matters. At its core, this is about keeping large, distributed systems predictable, even when the infrastructure underneath is anything but.
Faits marquants :
- Service mesh embedded into a zero-trust networking model.
- Centralized control across cloud, edge, and on-prem.
- Heavy use of automation for policies and components.
- Built-in observability and auditing.
Services :
- Zero-trust networking for distributed systems.
- Service mesh management.
- Policy enforcement tied to workload identity.
- Integrated logging and observability.
