The document discusses Juniper's data center network transformation assessment. The assessment involves reviewing a customer's existing data center environment and goals to evaluate options and plan improvements. It covers key areas like infrastructure, security, applications and management. The methodology consists of gathering requirements, documenting the baseline, analyzing gaps, and providing recommendations. The final report outlines findings, proposed solutions, impacts, and a roadmap. Assessments help customers optimize their networks to meet business needs and take advantage of new technologies.

DATA CENTER ASSESSMENT
What is it?
A review of a customer’s existing networking environment in light of their business and technical
goals.
It enables customers to evaluate technology options and plan their networking/security journey
whilst providing insight as to how a Juniper solution can potentially help meet their business
goals.
The need for an assessment is usually determined during a technical workshop near the start of
the sales cycle.
Juniper assessments are available for all product categories (DC, security, core, etc.) and are
based on a common delivery methodology

JUNIPER ASSESSMENTS:
A STANDARDIZED, GLOBAL METHODOLOGY
• An assessment is a consulting engagement very early in the project cycle. It provides:
• A detailed look at your business and technical goals
• An in-depth review of your existing network and/or security environment
• An analysis of that environment in light of your business and technical goals, identifying gaps
• Detailed recommendations for change, and expected business outcomes of those recommendations, based
on the latest technology options and industry best practices
Technology-specific adaptations

EXAMPLE:
A MAJOR INTERNATIONAL BANK
• Challenges to scale, host new services, or add resources because existing DCs were reaching limits of
Power, Cooling and Space.
• “Legacy” Multi-tier design was complex to manage, causing outages, human errors, and bugs.
• Complexity/Heterogeneity of legacy infrastructures with too many DC sites, contributed to High Capex and
Opex.
Challenge
Solution
Results
• Redesign and overhaul of legacy switching infrastructure, in favor of a high-performance flat DC-Fabric
deployment option.
• Homogeneous redesign of traffic-flows across sites / business-units / and functional segments.
• Leverage existing WAN MPLS network to provide DC Interconnect capabilities, in order to promote
flexibility, scale, and business continuity capabilities.
• The solution proposed delivers 50+ differentiations and improvements in the previously defined network
characteristics, enabling the Business Drivers. This includes:
• Increase 10G-enabled access rate from 1% to 100%
• 93% reduction in maximum East-West oversubscription
• Simplification of the main workflows by 70%
• 100% multi-homed and converged server connectivity
