The momentum away from on-premise infrastructure to placingworkloads in the cloud is well established.把IT业务负载从本地设施迁移上云的趋势已经非常明朗。
Indeed, many businesses yet to pursue a cloud strategy do soout of concern that the migration process will be too challenging andcomplicated.事实上，很多寻求上云战略的企业仍在顾虑迁移过程面临过多挑战性和复杂性。But in almost every case those issues need no longer be abarrier, particularly as private cloud services have evolved to offer a growinglist of advantages. But, where do the main challenges lie for users ofon-premise infrastructure, and how can private cloud offer a better option?基本上这些问题都不再是难题，特别是私有云服务已经逐步完善可以提供越来越多的优势性能。那么，仍然依赖本地部署设施的客户还面临哪些挑战？私有云怎样才能成为一个更好的选择呢？
Whether they like it or not, many organizations still relyheavily on legacy IT infrastructure that is hosted on-premise. Some are restrictedby budgets – a problem particularly evident across the public sector - whileothers use bespoke, mission-critical applications often seen as incompatiblewith the cloud. There are also many organizations that persist with oldtechnologies because it hasn’t broken - so why fix it?不管喜欢与否，很多企业和机构依然严重依赖目前本地部署的IT设施。有些受制于预算有限-特别是在一些公共部门，另外一些则因使用定制和承载关键应用，貌似不适用公有云。仍有很多企业和机构坚持用过时的技术，因为并没有出现故障-那有什么理由非要解决呢？Here’s one very good example that illustrates the problem withthat approach: in less than two months, Windows 7, still widely used across thepublic and private sector, goes ‘end of life’. On January 14th, 2020, Microsoftwill stop providing security updates and support for it, and users will eitherneed to pay for extended support, upgrade to the current version of Windows orkeep using it regardless of the increased security risks it will present in thefuture.这里又一个很好的例子说明问题的紧迫：在未来2个月内，在公共和私营企业部门目前仍广泛使用的Windows 7将“停止更新”。2020年1月14日后，微软将停止提供安全性更新和技术支持，客户需要为延长技术支持、升级到现有Windows版本而付费，如果继续使用将承受日益增长的安全风险。Clearly, that’s not a viable, long-term strategy, and for thatbig example, there are many similar issues out there on a smaller, but not lessimportant scale. For industries such as finance or government, moving toprivate cloud, where the solution is solely dedicated to the needs of anindividual client or organization, delivers the most up-to-date hardware,software, and services, removing the legacy burden and allowing users tobenefit from the latest product features and performance improvements.很显然，这不是可行的长远之计，除了上面Windows 7的例子，仍有很多稍小但同样紧要的问题广泛存在。对金融业或政府部门而言，迁移到私有云上可以满足个体客户或机构的特定需求，并提供最新的软硬件和服务，解除旧有负担，并让用户从最新的产品功能和性能改进中受益。Even when the age of technology isn’t a factor, investing inon-premise infrastructure where applications and data are located on-sitepresents a range of security risks. The costs of managing on-premise physicalsecurity to a high standard can create a significant financial burden. Incontrast, good private cloud providers will ensure all locations are Tier 3enhanced and ISO 27001:2013 certified. Their physical security measures, suchas 24/7 CCTV, biometric scanners, card readers and video monitors often exceedthose seen in on-premise facilities.即便技术的应用年限不是其中一个因素，仅在运行应用和存储数据的本地设施侧投资也意味着一系列安全风险。管理从本地物理安全升级到更高安全标准在费用上也将成为可观的财务负担。对比之下，好的私有云提供商将确保各托管场所达到Tier 3增强级和ISO27001:2013认证水平。私有云提供商的物理安全措施如24/7 CCTV、指纹/面部生物识别仪器、读卡机和视频监控器等设施都将优于本地部署。Similarly, if backups are only stored in the same building asphysical infrastructure, catastrophic data loss is always a remote possibilityin the event of a serious fire, for example. Migrating to the cloud allowsoffsite backups to be sent to another data center – reducing the possibility ofserious downtime.同理，如果备份只保存在同一栋建筑中以物理设施形式完成，灾难级数据丢失在类似严重火灾情况下就像达摩力克之剑。迁移上云可以实现灾备传送到异地其他数据中心，从而降低了严重宕机的可能性。Purchasing and maintaining software, hardware, servers, andother IT equipment via capital expenditure can be costly, with a high initialinvestment required build on-premise infrastructure. Along with the cost ofequipment, on-premise hosting requires space, electricity, cooling, networking,and physical security. In addition, there’s also the cost of employing theskilled technicians needed to build and maintain on-prem infrastructure.购买和维护软硬件、服务器和其他IT设施的资本开支不菲，而投资建设本地设施需要高额的初始投资。除设备成本外、本地托管还需要场地、电力、制冷和物理安全。此外，招聘技能熟练的本地设施建造和运维技术人员也需要资金投入。Taking the private cloud option is appealing to manyorganizations who don’t want the financial burden. A managed private cloudsolution can help to decrease that initial capital investment (Capex) and anyongoing operational expenses (Opex) by passing on the responsibility ofcreating or maintaining infrastructure to the service provider.选用私有云对很多顾虑财务负担的企业和机构非常具有吸引力。托管私有云方式可以把设施建设和运维交由服务提供商，以降低初始资本投入Capex和很多后继的运营成本Opex。Migrating to private cloud makes it easier for businesses toenhance application performance, reduce downtime and scale computing resources.Organizations running their own hardware on-site run the repeated risk ofbuying equipment that isn’t right for their needs or doesn’t work well withtheir applications. In those circumstances, problems have to be diagnosed andrectified in-house, or at greater expense, with the help of outside expertise.迁移到私有云让企业提升应用性能、降低宕机时间和弹性控制计算资源变得容易。企业和机构在本地硬件投资上可能会盲目购入并非真正所需或与应用匹配的设备。这原有模式下，故障必须要自己定位和排除，或者多花钱请外部专业人士协助。Private cloud migration, however, presents a good opportunityto streamline systems, build a better architecture and load balanceapplications. However, organizations considering their options for privatecloud should look for a partner that can provide a dedicated team of experts, abespoke migrations plan made up of informed recommendations that will deliverthe optimum performance for the entire organization.与此同时，向私有云迁移为精简系统提供了一个良机，可以顺势搭建更好的架构和优化负载均衡应用程序。不过，考虑采用私有云的企业和机构应该寻求可靠的合作方，由专家组参与并根据评审后的建议方案量身定制迁移计划，从而为整个组织实现性能优化。By moving on from the challenges of on-premise infrastructurestrategy and risky legacy hardware, organizations can build a private cloudsolution that blends performance, cost, and security for their precise needs.In doing so, they can arrive at a win-win situation where they have the dedicatedresources that were always the hallmark of on-prem, to a solution that deliversthe ongoing flexibility and power of the private cloud.在解决IT本地部署各种问题的前行路上，企业和机构可以通过私有云方案来解决其对性能、成本和安全性的精准需求。在实现过程中，企业和机构可以实现双赢的结果，在具备与本地部署同样专属资源的同时，升级为今后可以提供灵活性和功能的私有云方案。公众号声明：
