Financial services forex azul were among the early and enthusiastic adopters of Java - but the jittery Java virtual machines from Oracle and IBM and others before Oracle ate them have been forex azul pain forex azul some.
Azul Systems is hoping to cash in on that grief among big banks, brokerages, high frequency traders, and others in similar businesses, where microseconds drive millions of dollars in profits or losses and you can't wait for the Java Virtual Machines to do garbage collection.
As Sellers explained it to El Reg back in the summer ofwhen Zing was first being previewed, Azul never wanted to get into forex azul business of making its special Vega chips for running JVMs or the Vega Compute Appliances that were sold as Java offload engines for traditional Unix, Windows, and proprietary servers. However, back inwhen Azul was founded, x86 processors didn't have enough virtualization support. This prompted Sellers, Tene, and Shyam Pillalamarri forex azul the firm's vice president of engineering - to fix the garbage collection problem in hardware and then wrap a JVM around it with the Vega appliances, which started shipping in October Many generations of x86 processors have come and gone forex azul then, and the virtualization features in x86 processors from Intel and Advanced Micro Devices are now sufficient to the point that Azul decided to rip its JVM off its own Vega chips and port it to Linux running on x86 iron.
That is, in essence, what Forex azul is. To be more precise, the initial Zing 4 JVM from the summer of had a proxy architecture, which offloaded Java workloads forex azul a virtualized back-end appliance that functioned more or less like the Vega physical appliances. With Zing 5, which debuted in the fall ofAzul got rid of the proxy architecture and tuned up its variant of the HotSpot JVM which was licensed from Sun Microsystems in specifically for Linux operating systems running on modern Xeon and Opteron processors.
The JVM is designed to span multiple cores and threads and to have dynamic, rather than static, heap sizes that can grow to GB in size and substantially eliminate the garbage collection problems that other JVMs have.
This garbage collection issue is a big deal in financial services apps, where service level agreements are getting rougher and tougher. This means that having consistent forex azul — not just for 99 per cent of transactions, but for forex azul of them — is as important as having fast performance.
The secret forex azul is something that Azul calls C4, which is not an explosive but rather short for Continuously Concurrent Compacting Collector. This is what allows the Zing JVM to span forex azul of cores in a system and hundreds of gigabytes of main memory and deliver pauseless garbage collection. In October last year, with the current Zing 5.
Azul has not ported Zing to run natively on Windows, and figures that it doesn't have to with more than 60 per cent of the 8 million servers that support Java workloads using Linux as their operating system, compared to around 30 per cent for Windows, based on estimates that Sellers provided to El Reg.
And the Linux server base supporting Java apps is growing very fast, so the market is forex azul away from Windows and towards Linux as best as Azul can see. That said, the company has conceded that it will probably have to support its JVM running on Microsoft's Hyper-V hypervisor and Windows natively because Windows is still a big part of the Java server base. The FX trader originally used Hewlett-Packard servers when forex azul started, but switched to Dell boxes during last year's transition to Xeon E5 boxes.
The FX trading platform is able to match forex azul, orders forex azul second between currency buyers and sellers, and has peaked at around 40, trades per second under heavy load. This Equinix facility is forex azul where a lot of other financial services firms park their servers and applications, so the latency hop between forex azul is fairly small. And it has a fat and fast pipe into one of the seven Equinix data centers in the New York region this forex azul is in lower Manhattan.
The company is running tests on its applications right now using the Zing JVM, and McDaid says that LMAX Exchange expects the latency to come down and for the jitter issue to be substantially done away with. And, as is typical for super-secretive forex azul services firms, he doesn't want to talk about what kind of improvement he expects to see.
McDaid did say that forex azul software engineers at LMAX Exchange are going to spend less of their time trying to tweak their Java applications to deal with jitter and will be spending more of their time collaborating with software engineers at Azul to goose the performance of Zing and optimize it for low-latency trading environments.
Zing is distributed for free to open-source developers but is not open source so they can play around with it as they are developing code. But the minute you put forex azul in forex azul, you have to get a support contract. By forex azul with the Zing JVM and away from the Vega hardware appliances, Azul is not only trying to broaden its market, but also to forex azul up its business to make it an attractive takeover target from one of the established players in the Java racket.
