I am developing a high-traffic java web application. Currently I’m defining its architecture. I have some questions:

  • What are the key elements that we should consider while designing the architecture to handle load?
  • How to prevent web application from getting down or how to ensure high availability?

I expect hundreds of user logging in at a time. I am planning to keep data in application scope (static variables) to avoid lookups in the database. In session I am planning to store 5kB of data.

    I guess key elements I would consider would be:

    • Do you need cluster aware app servers?
    • Do you need hardware or software based load balancers?
    • What parameters will you record to determine the health of a server?
    • Will you load balance your DBs?
    • Will your app be I/O heavy? CPU heavy? Both?
    • Are you looking to utilize a lot of web traffic? If you’re averaging 5K of data per user, how many users will you be able to handle before you consider a link saturated?
    • Scale up vs scale out. Determine which one your app does best and exploit it.
    • Will there be a lot of DB transactions?
    • Will you be using Shared Storage?

    I hope this helps.
