DESCRIPTION

The VMware Cloud Infrastructure Architecture Case Study Series was developed to provide an understanding of the various components of the VMware Cloud Infrastructure Suite. The goal is to explain how these components can be used in specific scenarios, which are based on real-world customer examples and therefore contain real-world requirements and constraints. The VMware Cloud Infrastructure Suite consists of five technologies that together expand the capabilities and value that customers can realize from a virtualized infrastructure. This case study focuses on vSphere 5.0 and vShield App 5.0

VMware Cloud Infrastructure Architecture Case StudyPurpose and OverviewThe VMware Cloud Infrastructure Suite (CIS) consists of five technologies that together expand the capabilitiesand value that customers can realize from a virtualized infrastructure. CIS is designed to help organizations buildmore intelligent virtual infrastructures. It does so by enabling highly virtualized environments with theautomation, self-service and security capabilities that customers require to deploy business-critical applications,respond to business demands more quickly and move to a secure cloud model. The CIS is based on the VMwarevSphere platform as its foundation in pursuing any type of cloud infrastructure. In addition to vSphere, the CISalso includes VMware vShield App, VMware vCenter Site Recovery Manager Server (SRM Server), VMwarevCloud Director, and VMware vCenter Operations Manager.The VMware Cloud Infrastructure Architecture Case Study Series was developed to provide an understanding ofthe various components of the CIS. The goal is to explain how these components can be used in specificscenarios, which are based on real-world customer examples and therefore contain real-world requirements andconstraints. This document is the first in a series of case studies, with each case study focusing on a different usecase with different requirements and constraints.This document provides both logical and physical design considerations encompassing components that arepertinent to this scenario. To facilitate the requirements of this case study, these considerations and decisionsare based on a combination of VMware best practices and specific business requirements and goals. Cloudinfrastructurerelated components, including requirements and specifications for virtual machines and hosts,security, networking, storage, and management, are included in this document.Executive SummaryThis architecture was developed to support a virtualization project to consolidate 200 existing physical servers.The required infrastructure thats defined here will be used not only for the first attempt at virtualization but alsoas a foundation for follow-on projects to completely virtualize the IT estate and to prepare it for the journey tocloud computing.Virtualization is being adopted to decrease power and cooling costs, reduce the need for expensive datacenterexpansion, increase operational efficiency and capitalize on the higher availability and increased flexibility thatcomes with running virtual workloads. The goal is for IT to be well positioned to respond rapidly to ever-changingbusiness needs.After this initial foundation architecture has been successfully implemented, it can be horizontally scaled andexpanded when cluster limits have been reached, using similar clusters in a building block approach.Case BackgroundCompany and project background:The company is a financial institution.The project was initiated by the local insurance business unit.The vision for the future of IT is to adopt a virtualization first approach and increase the agility and availabilityof service offerings.This first foundation infrastructure is to be located at the primary site.The initial consolidation project targets 200 x86 servers, including 30 servers currently hosted in a DMZ, out ofan estate of 600 x86 servers, which are candidates for the second wave.TECH N I
