The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Scalable cluster architecture design - need opinion or an advise

Asked by 7workers in Web Hosting, Unix Networking, Computer Servers

Tags: cluster, mysql, apache, nginx, architecture, design

Hi experts!

I need to design an architecture for the big web application: big news portal + media hosting (pics, video, audio). Need to hold 400k active sessions  (up to 600k in peaks), 50Gb daily video uploads, 10Gb photo etc. Check the picture attached. Doing such thing for the first time. If you can see any flow in here please give me a hint.

Thanks.

The cluster:

Going to use VMWare ESX, real servers are 24 x Xeon Quad Core blade servers.

Storage: VMFS-connected to virtual-servers, HBA FC connected SAN to real servers, stores media files, >2TB

front servers: nginx, connected to shared storage to read static data

app servers: apache+php, serving dynamic HTML, authorization, media upload, connected to shared storage

memecache: memcached servers, session caching, heavy calculation caching etc

mysql cluster: going to run ndb+mysqld+ndb manager on each server, use load balancers

vconv: video converting, ffmpeg, connected to shared storage

admin will be the only one allowed to access all other servers via SSH plus few other thing.


Make me think i did everything right.

Thanks.
