Interruptions and inconsistency in the supply of market data can cause financial firms to lose as much money in a few minutes as they usually make in as many days. This makes market data distribution systems truly mission-critical. Market data needs to quickly flow from exchange feeds to the systems and people that need it with no outages, even through periods of extreme volume or volatility.
Solace’s high-performance messaging solution can route market data to many subscribers with low, consistent latency thanks to routing and filtration that are executed entirely in hardware. Solace’s use of discrete TCP-based client connections eliminates the two most common problems with multicast: slow consumers impacting other subscribers or the system as a whole, and clients wasting valuable CPU cycles filtering unwanted data. Client TCP connections also enable administrators to easily identify and address the root cause of problems at any level of granularity.
Advantages and Benefits
- Fast, predictable performance: Processing market data in hardware eliminates the variable latency associated with processing messages in software running on general purpose servers.
- Lower cost and complexity: Solace’s high-performance messaging appliance can handle the workload of as many as 30 servers, dramatically reducing architectural and operational complexity.
- WAN efficiency: Since Solace’s appliances are aware of subscriptions across the network, data is only forwarded to other appliances with relevant subscribers. And only one copy of each message is sent over the WAN, with fanout happening at the edge.
- Increased client efficiency: Client-specific subscriptions and feeds mean clients get exactly the data they need, so they don’t waste processing power deleting irrelevant packets.
