Setup a database cluster At a certain point you Brother cell phone list will need to setup a database cluster. A database cluster is just a group of servers that all have a copy of your database running. Your website will then connect to a random server in the cluster to get it's data. So if you have a database cluster with 3 servers, each server will handle 1/3 of the Brother cell phone list database traffic. The most common database cluster setup is master/slave, which means that there is one of your servers setup as the master and the rest are considered slaves. The Brother cell phone list master server is the one who is holds the original data and the slaves have copies of that data that they refresh every few minutes.
Separate your data to multiple databases Brother cell phone list Depending on your site and the date it stores, it might make sense to separate your data into a second (or third) database. This can be the same database type as your main application, like MySQL, or something different like MongoDB. Common things to separate are logging or historic data. For Brother cell phone list example with an e-commerce site it might be useful to have all of your product prices in the database but you can keep your historic prices in a separate database since they aren't used as Brother cell phone list ften. Ruby on Rails has support for connecting to multiple databases so it isn't too difficult to set up.
Use a database caching layer The fastest way to Brother cell phone list make your database quick is to never connect to it. This is what a database caching layer does. It sits between your Rails application and the database and will cache queries to your database for a short period of time. This means that instead of hitting your database for the same record 100 times, the Brother cell phone list caching layer will hit your database once and then serve up the cached record the other 99 times. Memcached is used for this most of the time and has great performance, but you need to take Brother cell phone list extra steps to make sure that it clears it's cache correctly.
