3050: 1834: 25: 1846: 200:, Amazon ElastiCache is designed to simplify the setup, operation, and scaling of memcached and Redis deployments. Complex administration processes like patching software, backing up and restoring data sets and dynamically adding or removing capabilities are managed automatically. Scaling ElastiCache resources can be performed by a single 263:
Leaderboards are an effective way to show a user quickly where they currently stand within a gamified system. For systems with large numbers of gamers, calculating and publishing player ranks can be challenging. Using Amazon ElastiCache with the Redis engine can enable high-speed at scale for

where an operation is allowed because a counter was not updated promptly. Using the ElastiCache for Redis atomic counter functions, where a single operation both checks and increments the counter's value, prevents race conditions.
391:
Using the online management console is the simplest way to monitor ElastiCache with CloudWatch. It allows to set up basic automated alerts and to get a visual picture of recent changes in individual metrics.

Some APIs only allow a limited number of requests per time period. Amazon ElastiCache for Redis engine can use incremental counters and other tools to throttle API access to meet restrictions.

As an AWS service, ElastiCache is designed to be accessed exclusively from within AWS, though it is possible to connect the service to applications and databases that are not hosted by AWS.

Using ElastiCache for database performance acceleration can significantly reduce the infrastructure needed to support the database. In many cases, the cost savings outweigh the cache costs.

require a 1-year or 3-year commitment, which dedicates cache resources to the owner. The hourly cost of reserved nodes is significantly lower than the hourly cost of on-demand nodes.

Amazon ElastiCache was first released on August 22, 2011, supporting memcached. This was followed by support for reserved instances on April 5, 2012 and Redis on September 4, 2013.
