Hertz Corporation

The client is a global American car rental company, providing quality car rental service for over 90 years.

The client needed a Datacenter/Cloud Network Engineering Consultant to design and implement a multitenant data centre infrastructure, such as creating different service delivery nodes and protected subnets for each tenant. As a Datacenter/Cloud Network Engineering Consultant, our team was responsible for the design, development, integration, testing, deployment, and ongoing maintenance of multitenant data centre and cloud networks.

The client selected EES as their Datacenter/Cloud Network Engineering Consultant due to our proficiency in a wide range of cloud-related fields, including but not limited to: Cloud Infrastructure Design, Cloud Infrastructure Implementation, Security Infrastructure Design, Core Routing Infrastructure Design, Virtualization Infrastructure Design, Compute Infrastructure Design, Storage Infrastructure Design, and Software Defined Network Design.
