數字化轉型面臨的挑戰
基於開源Kubernetes+Docker技術構建CaaS平臺過程中
客戶IT人員配備、技能要求等方面都遇到了較大挑戰
大資料分析應用已接近投產
客戶急需Production Ready的穩定可靠、快速交付的CaaS平臺以加速Time to Market。
大量的應用系統部署於不同的公有雲
資料散佈在不同的公有雲上難以進行整合的大資料分析

數位化轉型面臨的需求
 IaaS VM需求：
➢ 30 VMs：8C/16G/200G Disk
➢ 30 VMs：16C/32G/500G Disk
 PaaS需求：
➢ 100 large size pods - 1 vCPU/512~1024M Memory for each pod
 其它需求：
➢ 確保平臺高可用能力：支持VM & Container、Disk、Node、DC等多種級別的高可用能力
➢ 提供商業化、經驗證的支援Kubernetes + Docker容器即服務平臺，快速構建，確保不會出現相容性風險
➢ PaaS平臺與IaaS平臺相容，並基於IaaS平臺基礎上進行構建
➢ 運維監控：平臺需提供完善的對IaaS及PaaS平臺的監控告警能力
➢ 售後支持：需要對平臺所有軟硬體提供統一的商業化售後支援服務
➢ 支援自動化部署及全自動化生命週期管理能力，簡化部署及運維的複雜度
