Recovery time objective(RTO), and Recovery point objective(RPO) are two important terms businesses use while building fault tolerant applications, and databases.
RPO: How much data are you willing to lose?
RTO: How much time to recovery from a failure?
Disasters are in the news, and it is easy to recognize the value of having the right insurance, Data Insurance.
The Informix Dynamic server implicitly provides you with some basic insurance by automatically maintaining physical and logical logs to provide data integrity should something abruptly stop the server. But that may not be enough when there is a disk failure, corruption, or a flooded server room. While Informix support can help solve many problems, some problems can only be resolved by restoring from a backup.
The Internet of Things (IoT) has taken off and we now see it everywhere. Open Source software packages have been around for many years but recently we have also seen Open Source hardware take off. Now I find myself playing with hardware again after too many years of doing just software development. Open Source hardware has made it so much easier and inexpensive to build electronic gadgets and especially IoT devices. It also comes with a big fun factor.
In this blog, I am going to discuss my first project that was not out of some Arduino or Raspberry PI project cookbook. Here we are going to combine some Open Source hardware along with the Informix database server to collect and analyze GPS data from a vehicle using a homemade IoT gateway.
