Migrating to the cloud means you should be able to deploy your apps, systems and services quickly with minimal downtime. This tends to be a much simpler process than buying servers, installing the needed operating system, and placing it into a network or data center. Additionally, data centers require physical racking and staff to replace hardware should something fail.
Cloud systems reduce the complexity of the infrastructure that underlies the architecture being used to provision new machines and make them all work together to provide the needed services. monitoring, backup and logging services are extremely important, especially if you need to perform disaster recovery from an outage and see where things went wrong.
With cloud services, your team won’t need to be at a specific location to deploy, update, or fix issues with any of the various machines being used. This makes it a more flexible solution when compared to the necessity of being on-site.
