Service Mesh Will Solidify Positioning in Cloud-Native Market

By William Morgan, co-founder & CEO, Buoyant

The world of cloud native computing is rapidly maturing. What was once a wild west of competing container orchestrators, conflicting application design patterns, and an ever-shifting landscape of small projects is now solidifying around a few key technologies. Most prominent among these, of course, are a set of open source offerings hosted by the Cloud Native Computing Foundation: projects like Kubernetes, Prometheus, Linkerd, and other "graduation-tier" projects have coalesced from the fog of confusion to become the pillars of most modern cloud native deployments.

But evolution in the space is far from over. The service mesh, in particular, has come a long way since its (notoriously marketing-heavy) beginnings, but continues to push both organizational and technology boundaries, especially when it comes to security. Having been a part of the service mesh space since its inception, here are my predictions on how this space will evolve over the next year:

Prediction: The service mesh will solidify its role as a critical component of the cloud native stack.

In 2022, service mesh adoption will continue to cross the chasm from early adopters to majority adoption within the cloud native ecosystem. This year, we saw widespread realization that "just throw it on Kubernetes" is not enough for a functioning cloud native application, and that the addition of a service mesh solves fundamental concerns about security, observability, and reliability. Next year, these realizations will come to their logical conclusion and the service mesh will become the norm, not the exception, for Kubernetes applications.

Prediction: the choice of service mesh will be dominated by operational concerns.

Clunky, Envoy-based service meshes will increasingly be seen as a thing of the past. While early service mesh adopters were neophiles who were enthusiastic about the technology for its own sake, the complexity of running Envoy at scale often resulted in failure to actually adopt the technology in practice. In 2022, appetite for memory-hungry and insecure C++ systems will be at an all-time low, and projects like Linkerd-which avoids Envoy, opting instead to use a set of ultralight, minimalist Rust proxies-will be the focal point for adoption. In 2022, increasing performance and reducing operational complexity of the service mesh will be paramount, and simplicity and performance will be the watchwords of the day.

Prediction: Zero-trust network security will rise to the forefront of organizational security concerns.

As organizations fully adopt cloud native, the security surface area of their applications will inevitably require rethinking. Old approaches that rely on network identity, host-based network stacks, and firewalls simply don't measure up to this new world, even when dressed up in the fancy clothes of eBPF. Instead, the "zero trust" model of security will become dominant, with strong workload identity rather than network identity becoming the critical foundation. The service mesh, with its focus on mutual TLS and on workload identity, will provide the most forward-thinking solution here. I predict that we'll see security teams as well as auditors themselves will place increasingly sophisticated demands on the network security of their applications.
