                 --  Its  a  basically a general purpose time-series metrics repository.

                 --  Many AWS services publish data to Cloudwatch.

                 --  Many AWS services consume and act on metrics published to cloudwatch

                 --  Custom metrics can also be submitted from any where

                 --  Alarms can alert on built-in or custom metrics

                 --   Below are the popular ways to interacting with Cloud Watch.

• CloudWatch Core Concepts

                         i)  Namespaces      :   An abstract container to store and provide context to data while                                 preventing collision of similar metric names.  

                                             --Namespaces looks similar to a unix directory structure.

                                            -- AWS services reside in the AWS/Namespace.

                                            -- Each AWS service has its own namespace such as AWS/EC2/.

                                            -- Custom namespaces can be created for custom metrics.

                         ii)  Dimensions 

                                  --    A name -value pair that contains information to help identify a metric.

                         iii)  Metrics
