Web application stopped behaving normally after migration from Dedicated servers to Ec2 servers
Old Dedicated Server configuration
systemtype: 32 bit operating system.
RAM: 3.99 Gb Ram
Processer : 1.86 GHZ
New Servers in EC2
systemtype: 64 bit operating system.
RAM: 3.99 Gb Ram
Processer : 2.73 GHZ - 2.31 GHZ
Everthing is working fine in our production server.
But as we migrated our web application from old servers to new servers and transferred the entire network traffice to new servers.Site suddenly stopped behaving abnormally.
Sometimes it's super fast
Some times slow.
sometimes normal
some times super slow
and sometimes no response
This all above happens with a time interval or around 2 - 3 minutes.
This went on happening 8 - 10 hours.
Few differences in old and new servers are
Old servers are using II6 and New servers are using IIS 7.5.
We are using exactly the same code in the old and new servers.
Even the ec2 servers are having higher CPU then older servers but still having lower.
But not sure how this is happned.
Please suggets your views...
