Question - Explain how you can minimize the Memcached server outages?

Answer -

When one instance fails, several of them go down, and this will put a larger load on the database server when lost data is reloaded as a client make a request. To avoid this, if your code has been written to minimize cache stampedes then it will leave a minimal impact
Another way is to bring up an instance of Memcached on a new machine using the lost machines IP address
The code is another option to minimize server outages as it gives you the liberty to change the Memcached server list with minimal work
Setting timeout value is another option that some Memcached clients implement for Memcached server outage. When your Memcached server goes down, the client will keep trying to send a request till the time-out limit is reached
