Modern cloud applications are built on top of different networks often located in geographic regions where their user base is most active. Latencyĭata replication helps reduce latency of applications by keeping copies of data close to the end user of the application. This means also keeping child nodes up to date with the master node so everyone stays up to date. Keeping a master copy is important, but it is equally important to keep that copy up to date as much as possible for all users.
By replicating the latest changes to other nodes or servers, it should be instantly available to users who are accessing those other nodes. Availability is affected when concurrent sessions do not share or replicate their data effectively. This refers to making sure all data is ready for use when requested, with the latest versions and updates. These particular areas are commonly discussed when talking about cloud data replication: Availability
Then they need ways to keep data secure and located efficiently. These are basic topics that any developer has had to deal with, but they are even more important when applications go global and/or mobile. There are many reasons for building applications that understand replication, with or without cloud support.
