Pros & cons.

Third party API PaaS• Advantages– Development Costs

• Efficient• Time-to-market (short)• No maintenance

• Drawbacks– Operation Cost

• PaaS provider margin– Lack of flexibility– Lack of control

Owned infrastructure• Advantages– Operation Cost

• No margins to pay– Full flexibility– Full control

• Drawbacks– Development Costs

• Complex• Time-to-market (long)• Maintenance

Some numbers

API PaaS Costs*• API PaaS dependent

– Min around 0.1$ – Average around 0.3$– Max around 3$

Your own infrastructure*• Cloud provider dependent

– Around 0.01$ per video hour

* Costs are calculated in hourly basis, costs assume video 500Kbps video streams

Elastic scalable version of Kurento Media Server– Same API as Kurento Media Server– Leverages the cloud capabilities of AWS– Enhanced cloud features

• Autoscaling• Self-provisioning

– Enhanced media features• Simulcast• Multistream support• Unified plan support (almost ready)• S3 recording

– Enhanced development features• Runtime inspector

Using elasticRTC

http://www.kurento.org - lulop@kurento.org14

1. Open an AWS account• Get your AWS

credentials

2. Execute the elasticRTC script• Provide your AWS

credentials

3. Enjoy• Develop with the same

Kurento API• Transparent

autoscaling

$ ./elasticrtc create \ --region eu-west-1 \ --stack-name mycluster
