What is FluxNinja Aperture?
Aperture is an intelligent load management platform for cloud native applications. Aperture provides capabilities such as concurrency limiting, rate limiting and auto-scaling.
Why is flow control needed?
Modern cloud application architectures such as microservices are vulnerable to cascading failures in face of sudden loads, new deployments and performance issues. Reliable operation is impossible without effective flow control. In addition, flow control enables graceful degradation, which is the ability to preserve key user experience pathways even in the face of application failures.
Features
At the fundamental level, Aperture enables flow control through observing, analyzing, and actuating, facilitated by agents and a controller.
-
Aperture Agents live next to your service instances as a sidecar and
provide powerful
flow control
components such as a
weighted fair queuing scheduler
for prioritized load-shedding and a
distributed rate-limiter.
A
flow
is the fundamental unit of work from the perspective of an Aperture Agent. It
could be an API call, a feature, or even a database query. -
Aperture Controller is the "brain" of system. It is powered by always-on,
circuit graph driven policies
that continuously track deviations from service-level objectives (SLOs) and
calculate recovery or escalation actions.
