Cisco Virtualized Multi-Tenant Data Center Solution 2.2
The Cisco® Virtualized Multi-Tenant Data Center (VMDC) architecture is a set of specifications and guidelines for creating and deploying a scalable, secure, and resilient infrastructure that addresses the needs of cloud computing. To develop a trusted approach to cloud computing, Cisco VMDC combines the latest routing and switching technologies, advancements in cloud security and automation, and leading edge offerings from cloud ecosystem partners. Cisco VMDC enables service providers (SPs) to build secure public clouds and enterprises to build private clouds with the following benefits:
•Reduced time to deployment—Provides a fully tested and validated architecture that enables technology adoption and rapid deployment.
•Reduced risk—Enables enterprises and service providers to deploy new architectures and technologies with confidence.
•Increased flexibility—Enables rapid, on-demand workload deployment in a multi-tenant environment using a comprehensive automation framework with portal-based resource provisioning and management capabilities.
•Improved operational efficiency—Integrates automation with multi-tenant resource pools (compute, network, and storage) to improve asset use, reduce operational overhead, and mitigate operational configuration errors.
VMDC 2.2 Solution Highlights
Details of Release 2.2
Validated data center design for enterprise or service provider scalability
Builds on top of the baseline that was established in release 2.0, validating standard data center architectures in a multi-tier, Layer 3-centric network architecture with compact to large scale specifications, using standard integrated compute stacks such as Cisco FlexPodTM and VCE VblockTM Infrastructure Packages.
Enhanced security services for improved secure multi-tenancy
Extends the security model that was established in release 2.0, which among other benefits enabled secure multi-tenancy by adding "defense in depth" strategy using Cisco Virtual Security Gateway (VSG) and Cisco Adaptive Security Appliances (ASA).
Supports the same set of differentiated services defined in release 2.0 and 2.1, Gold, Silver, Bronze, and Palladium.
Multi-media application support
Extends and validates the campus quality of service (QoS) model to the data center, enabling higher quality of experience for multi-media applications such as VoIP, video, and hosted collaboration.
Layer 2 data center interconnect
Validates Virtual Private LAN Services (VPLS) and Ethernet over Multiprotocol Label Switching (EoMPLS) on the Cisco Aggregation Series Router 9000 (ASR 9000) for data center interconnect, enabling SPs to seamlessly connect their data centers through their IP-NGN networks for intra-data center connectivity as well as hybrid cloud support for connecting enterprise data centers.
Builds on top of the release 2.0 baseline and revalidates the scalability of the large pod model for parameters such as VLANs, MAC addresses, Hot Standby Router Protocol (HSRP), routes, contexts, and virtual machines.
Revalidates the end-to-end security validation that was designed in release 2.0 and extended with enhanced security services for secure multi-tenancy.
Revalidates failover scenarios and the high availability of the system as designed in release 2.0.
Validates new platforms such as the ASR 9000 for data center edge, Cisco ACE30 Application Control Engine Module for virtual Server Load Balancing (vSLB), ASA5585X for virtual firewall (vFW), and VSG for virtual machine (VM) security.
