Thomas Hatch, SaltStack CTO, and Sam Smith, SaltStack director of product development, introduce SaltStack RAET as a new alternative transport medium developed specifically with SaltStack infrastructure automation and configuration management in mind. SaltStack built RAET for customers needing substantial speed and scale to automate management of massive data center infrastructure environments. SaltStack RAET is primarily an async communication layer over truly async connections, defaulting to UDP. The SaltStack RAET system uses CurveCP encryption by default. SaltStack users can now leverage substantial flexibility via either Salt SSH, ØMQ, or RAET to best address numerous use cases.

The need for speed From server closet to Web scale, speed and
flexibility matters;! SaltStack built for speed and scale at any
level;! SaltStack supports:! SSH! Good for limited use cases! 50x
faster than other other SSH-based tools! MQ! Super fast! Good for
many use cases, but! RAET (Reliable asynchronous event transport)!
Even faster! From tens of thousands to hundreds of thousands!
Driven by customer demand (massive infrastructures)! More control
and infrastructure visibility
MQ background and overview MQ! The fastest of the integrated
queuing services! Integrates PubSub Queueing into custom TCP
Sockets! Difficult to observe and manage problems under load! TCP
socket delays, reconnect problems! Suited for multi-process
architectures, context switching overhead, blocking I/O! TCP
connection limits, presence, latency
SaltStack RAET protocol Bringing established automation
technology to Salt;! Built on a precedent of successful automation
concepts;! Support for UDP sockets in addition to TCP;!
Transactions for reliability;! More async;! Built in crypto
(CurveCP);! Built to run on Python2, Python3, PyPy. 5
SaltStack RAET layering Micro-threaded architecture with
non-blocking I/O;! Separates event Pub / Sub queue from
socket-based transport layer;! Optimize queueing and transport
independently;! More modularity;! Better observability of issues
and management of performance under load;! More fine-grained
management of events;! More maintainable code.
SaltStack RAET architecture Modular and nested architecture!
Inter-host communication is transactioned UDP! Inter-process
communication is paged UXD! Unified event-message routing! Fully
signed and encrypted UDP comms
SaltStack RAET Built for massive scale to support SaltStack
Enterprise customer environments;! Go faster;! Driven by customer
and user requirements;! More flexibility (SSH, MQ, now RAET);! Salt
on RAET appears the same to the user as Salt on MQ. 8
