Feed: Blog Post – Corporate – DataStax Author: Robin Schumacher I missed it by just a few hours. I tend to always fly Delta because they have the best options for travel given where I live. I landed pretty late in San Jose on Sunday for some training our team is running, and got in under the wire just before Delta suffered a power outage in its Atlanta headquarters that brought its global business to a halt. The downtime that originated in their Atlanta location affected every site in which Delta does business around the world. Such an event puts ... Read More

Feed: Blog Post – Corporate – DataStax Author: Robin Schumacher Like me, I’m sure you’ve come to the world of NoSQL from relational database management systems (RDBMS) such as Oracle, MySQL, SQL Server, etc. And like what happened to me a couple of years ago, maybe you’ve just recently seen that a type of NoSQL database – graph – has been increasing in popularity and getting lots of attention lately. Why is graph gaining ground right now? If you’ve read anything about graph databases, you know they manage and uncover the value in relationships between data objects better than any ... Read More

Feed: Blog Post – Corporate – DataStax Author: Matt Kennedy Two factors critical to the success of any Cassandra / DataStax Enterprise implementation are: (1) a well architected data model; (2) fast storage. While the first challenge is typically solved on a per-application basis, the second is somewhat more general and straightforward to address. Using locally attached solid-state drive (SSD) storage on dense conventional Linux servers is a good first step. SSDs have quickly become the de-facto standard in database applications due to the sheer power of the cost per input/output operation (IOP) compared to legacy mechanical hard drives (HDDs). A ...

We all know the view from the trenches when there’s an operations or security issue. Everything’s on fire, sysadmins are scrambling, information is missing, accusations are flying and no one has a cohesive view of what actually happened. What fewer people know is the view from the C-suite.As a CIO, CISO having risen through the ranks, the inclination is to roll up your sleeves and dive in. The only problem is you have no idea where to dive into. You have dozens of monitoring tools, each with a different sample of a different part of the infrastructure. It’s like looking ... Read More
