Terremark offers Cloud Express, a cloud designed for developmental teams and department needs. This offering permits quick setup and gives their clients access to flexible, high-performance computing, how and when they need it. The client can configure resources exactly as they are needed, and pay as they go.
Terremark cloud users can harness the extra level of security and control in the cloud with the VPN-Cubed Overlay Network. Terremark offers the VPN-Cubed IPsec Free Edition and SSL Free Edition.
Terremark’s main offering is called Enterprise Cloud. It offers precise, dynamic allocation of computing resources, with the scale, performance, and security to handle enterprise-wide applications. Its solutions offer multiuser capacity, dedicated resource pool architecture, and a role-based security model, as well as private network connectivity and physical device integration.
The Enterprise Cloud combines the power and flexibility of IaaS with the expertise, security, and availability that large organizations with mission-critical computing needs demand of their infrastructure. It provides An easy-to-use Web-based management interface that gives its clients command and control over a cloud-based resource pool of compute, storage, and network, built on a fully clustered enterprise-class computing architecture featuring virtualization technology from VMware.
Terremark’s charges are based on resources rather than on large and inflexible server units, allowing for more precise and dynamic allocation of computing resources when and where they’re needed.
The Enterprise Cloud supports more than 450 operating system configurations, including Windows Server 2003 and 2008, Red Hat Enterprise Linux, CentOS, FreeBSD, Solaris, SUSE Linux, and Ubuntu. If you have pre-existing ISOs or custom OS needs, you have the freedom to upload and install on blank virtual machines.
The Enterprise Cloud can be combined with your dedicated servers and managed from the same Web-based interface. Exposing this server in The Enterprise Cloud takes only a few minutes; once a LAN-LAN connection is established, you have complete control over these dedicated resources. This provides the best of both worlds—the elasticity of the cloud combined with the security and compliance of dedicated hardware.
