Architecture with Perl Solution
At first, let's look at the picture the following.
you saw Load balancing it might be hardware as F5 BigIP or four layer swith as LVS(Linux Virtual Server).
here we need two machine for that. one is Primary, the other is Secondary. the Primary and Secondary connect to each other by heartbeat. the heartbeat line you might choose serial port(ttyS0) or ethernet(eth1).
secondly, it is cache by reverse proxy. I thought that I needn't said it. we have a lot of node for cache.
next, has three part of cluster on the application.
1. static cluster (html archives)
2. active cluster (perl script)
3. multimedia cluster (image, flash and extra)
we have two way for you.
one way, apache with mod_perl, two way is lighttpd with fastcgi. whichever ways is OK all.
also we have a lot of node for active cluster, and each node to synchronize to each other via csync software.
I used memcached in the between perl script and database.
the database is MySQL Cluster, also has a lot of node.
has some data must be to generate html archive. I also using csync to synchronize to each other node.
I will all of multimedia put on else cluster.
and using DFS(Distributed Filesystem) by storage.
also has a lot of node for multimedia cluster.
welcome to discuss with me.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
