As I was working on my review of DeepSQL I received an inquiry from another company claiming to have a scale-out relational database that can handle large-scale (“Cyber Monday shopping traffic”), write-heavy loads, while maintaining ACID compliance and scaling linearly with little to no latency. In other words, this company, Clustrix, had another database more scalable than Amazon Aurora for some scenarios. My response: “There seems to be a lot of that going around.” I must be getting cynical in my old age. Nevertheless, ClustrixDB turned out to be real, a MySQL-compatible transactional database that can be scaled out “hot” ... Read More

It's a well-known fact in the IT world: Change one part of the software stack, and there's a good chance you'll have to change another. For a shining example, look no further than big data. First, big data shook up the database arena, ushering in a new class of "scale out" technologies. That's the model exemplified by products like Hadoop, MongoDB, and Cassandra, where data is distributed across multiple commodity servers rather than packed into one massive one. The beauty there, of course, is the flexibility: To accommodate more petabytes, you just add another inexpensive machine or two rather than ... Read More

Another way to say the same thing is that if we put the cards back, shuffle and deal again, the odds are worse than 1 in 300,000 that we'll deal the same hand again. It's very unlikely. It's also unlikely, less than a 1/4 chance, that even just one of the cards will match between the two hands. And to complete the ... Read More

Feed: AWS Architecture Blog. Author: . Practically every experienced driver has suffered a flat tire. It’s a real nuisance, you pull over, empty the trunk to get out your spare wheel, jack up the car and replace the puncture before driving yourself to a nearby repair shop. For a car that’s ok, we can tolerate the occasional nuisance, and as drivers we’re never that far from a safe place to pull over or a friendly repair shop. Using availability terminology, a spare tire is a kind of standby, a component or system that is idly waiting to be deployed when ... Read More
