    Default Wowza, Varnish, Apache on a Large EC2 Instance, good idea?

    I have a large ec2 instance running Wowza, Varnish, and Apache. I do experience slow server response (with very few users) few times a week . Is it a good idea to run all 3 services on one single instance? Or should I move the Wowza to a separate instance?

    Thanks!

    Hi
    I think before you make a decision to move any services you should determine what's causing the slow response.
    When you experience low performance can you check to see which service is using the cpu on the server?

    Jason,


    Thanks for your swift response. Yes I have and nothing stood out

    Let me provide a little bit more details;

    EC2 website features:
    1. One to one & Many to Many Video/audio/text Chats
    2. Social Networking
    3. Forums/News Feed/Blogs/Message Posting Feature

    I would like to know what is the best practice to setup instances on amazon as we are expecting good number of concurrent users on our website at the same time. The libraries/services required by our website on EC2 are:
    1. Wowza 3.5 Media Server
    2. Apache Web Server
    3. Varnish Cache Server.
    4. Mysql 5 +

    The problem being faced includes:

    1. Instance showing high system load averages which is causing slow response on the server and increased website load time.
    2. How can we set automatic backups of our website data on the server?

    Thank you!

    Ade

    Hi
    Unfortunately using EC2 does have its disadvantages, the CPU and disks are shared between you and other EC2 customers.
    If you're sharing with another customer who may be overloading the server you'll get slow response times on both CPU and disk I/O.

    This will of course cause system load averages to be higher than normal.
    If this is the case then moving Wowza, or one of the other services to another EC2 server may be your best course of action.
