 # Why
 
 ECS may often seem expensive when used for personal development purposes, because of the cost of the load balancer.
-The application load balancer is a great service because it is easy to set up managed ACM certificates, it scales, and has dynamic port mapping, 
+The application load balancer is a great service because it is easy to set up managed ACM certificates, it scales, and has dynamic port mappings and so on,

 The ECS service occupies the host port, only one service can be run at a time.
 The old task must be terminated before the new task launches, and this causes downtime on release.

 Also, if you make changes that require recreating service, you may need to manually terminate the task of old the service.
