With Smart EMS you can schedule downtime (nights and weekends) for your non-production environments. You can scale your production environments to include additional web and app servers during the day, and fewer at night. Your environments will autoscale for small variations in traffic during the day and can be massively scaled for known events like registration or reporting.
New environments can be created with very little notice to accommodate ad hoc projects. Your environments are built based on an extremely well tested architecture, so the environments are exceptionally robust. All of the above saves you money and makes you more productive.
