Pressure points
The client operated a large-scale, heterogeneous AWS environment spanning multiple platforms, including VMware on AWS, EC2, VMware Horizon, and AWS WorkSpaces. Over time, this ecosystem expanded organically, leading to fragmented operations, inconsistent security practices, and lack of cost visibility. This complexity resulted in frequent service disruptions and limited ability to proactively manage performance, security, and costs.
No unified visibility across platforms, leading to siloed operations and reactive incident management
Inconsistent security posture and patch compliance across the cloud estate
Lack of structured cost governance – no reliable chargeback or show back mechanisms for internal business units
High frequency of major incidents impacting service reliability and end-user experience Sonata's Approach
