There are not many settings that need to be provided while creating a log group. We can use this log group within other recipes where we log into CloudWatch. A log group is a group of log streams. A log stream is a sequence of log events from the same source. Log streams within a log group share the same retention, monitoring, and access control settings. We can specify which streams to put into each log group. There is no limit on the number of log streams in a log group.
