Platforms as Services (PaaS) are garnering a lot of attention from developers and enterprises these days for a lot of reasons. Knowing that language flexibility is core to PaaS success, Google has the most popular languages covered in Google App Engine now that it has added support for .NET and PHP.
Plivo was founded after its founders, Venky Balasubramanian and Michael Ricordeau, found each other on Github and collectively decided, "[t]elephony is complex." Today, Plivo's focus is simple in statement, but complex in execution: Plivo offers "simple and powerful APIs that make it easier for businesses to develop telephony applications." Plivo's building block APIs allow developers to create telephony applications without learning the nuts and bolts of legacy telephony.
