UFW is the default firewall configuration in Ubuntu. It provides an easy method to create the firewall for both IPv4 and IPv6 traffic. Wowza Streaming Engine is one of the leading streaming software in the media industry. Using Wowza you can deliver streams through different protocols like RTMP, RTSP, HLS, MPEG-DASH, HDS, Smooth Streaming. Following are the port numbers assigned to the respective protocols
Live transcoding is a CPU consuming process and if you are transcoding/transrating multiple live streams, you need GPU support to manage the load of the server. Recently I got a live transcoding task to do using AWS Ec2 instances. AWS provides two types of GPU based instances (at the time of writing)
In general on fly live transcoding requires more compute cycles for converting multiple bitrate live streaming. After some research, I found a suitable motherboard and Intel quicksync processor for Wowza Streaming Engine live transcoding for one of my project.
I have compiled Wowza with Intel quicksync successfully on linux and now I can see drastic changes in cpu consumption. It almost reduced to 50% from actual usage.

Few days back I was trying to redirect all my http traffic to https by default with help of an elastic loadbalancer mounted with two webservers. I have enabled both 80 and 443 port numbers in listener section and added SSL certificate.
I’m having a personal website hosted at AWS EC2 with ELB. Today I have started my AWS EC2 instances (I had turned off due to non usage and Of course, I can save some cost) and tried to load my website via AWS Elastic loadbalancer public dns url but it was not coming up in my browser, instead of webpage I got a blank white page. So I checked my AWS EC2 instances and ELB services.
Today Amazon Cloudfront announced graph based usage reports for Web HTTP distributions. I was awaiting for this feature for a long time and I’m very happy about it. It’s not available for RTMP based distributions by this time. I hope AWS will enable the graph report soon.
