Promise Theory

Promise Theory

The way we have created IT systems over the years has been very linear with each individual component being statically configured. If a human makes an error in any one of the many configurations, then the whole system breaks down. ...

Software Containers: Used More Frequently than Most Realize

Whether you have considered trying to secure an application by putting it into a “sandbox” or wondered how a Software as a Service (SaaS) provider keeps your application and data isolated from other customers, you have been...

ARIN Enters Phase 4 of IPv4 Exhaustion

After IANA allocated the final IPv4 addresses to the five Regional Internet Registries (RIRs) on February 3, 2011, the RIRs have been running out of IPv4 addresses over the past three years. APNIC ran out on April 15, 2011; RIPE NCC...
