Exoscale vs NATS
A side-by-side editorial comparison of Exoscale and NATS — release velocity, themes, recent moves, and the top alternatives to consider.
Exoscale vs NATS: at a glance
What is Exoscale?
Exoscale lets customers keep their own encryption keys outside its cloud.
Exoscale, a European cloud provider, opened a private preview of KMS External Key Store on 3 November: customers connect Exoscale KMS to their own HSM or key manager through a proxy they host, and Exoscale never sees the key material. It implements the AWS KMS XKS proxy API, so existing proxies work unchanged. This follows a free VPC in every zone in October, object-storage lifecycle rules, asymmetric KMS keys and cheaper IPv6 load balancing.
What is NATS?
NATS keeps two release lines in lockstep while slowly widening multi-tenant routing controls.
NATS maintains 2.14 and 2.15 in parallel, shipping matching patch and RC releases on both. The latest RCs add account-hash subject mapping functions and a new TLS verification option, while the October patches were mostly Go toolchain bumps carrying a certificate-trust CVE mitigation.

Exoscale lets customers keep their own encryption keys outside its cloud.
◆ Current state
Exoscale, a European cloud provider, opened a private preview of KMS External Key Store on 3 November: customers connect Exoscale KMS to their own HSM or key manager through a proxy they host, and Exoscale never sees the key material. It implements the AWS KMS XKS proxy API, so existing proxies work unchanged. This follows a free VPC in every zone in October, object-storage lifecycle rules, asymmetric KMS keys and cheaper IPv6 load balancing.
◆ Where it's heading
KMS has moved fast: asymmetric keys in early October, external keys four weeks later. Together with VPC and lifecycle rules, Exoscale is closing gaps against the hyperscalers, and XKS points its pitch at sovereignty-bound customers who need to prove the provider cannot decrypt their data.
◆ Prediction
XKS will likely widen from private preview to general availability, and the next steps are probably more services encrypting with KMS keys; the entries don't say which services or when.
NATS
5.0DEVOPS
NATS keeps two release lines in lockstep while slowly widening multi-tenant routing controls.
◆ Current state
NATS maintains 2.14 and 2.15 in parallel, shipping matching patch and RC releases on both. The latest RCs add account-hash subject mapping functions and a new TLS verification option, while the October patches were mostly Go toolchain bumps carrying a certificate-trust CVE mitigation.
◆ Where it's heading
The project is in a stabilization phase: JetStream placement limits, gateway compatibility and security patches dominate. The new account-hash mapping functions are the only feature thread, aimed at operators running many isolated accounts and leafnodes.
◆ Prediction
Expect 2.15.3 and 2.14.10 to go final with the account-hash mapping functions, followed by more JetStream placement and limit fixes.
