Cloud Computing Principles and Paradigms: 11 t-systems cloud-based solutions for business applications - copy

  1. 1. 27 April 2013 Cloud Computing: principles and paradigms - Part III 1 11-T-SYSTEMS’ CLOUD-BASED SOLUTIONS FOR BUSINESS APPLICATIONS MICHAEL PAULY Cloud Computing Principles and Paradigms Presented by Majid Hajibaba
  2. 2. 27 April 2013 Cloud Computing: principles and paradigms - Part III Introduction • T-Systems • ICT service provider • Offers IT, telecommunications, integrated ICT services • 75 data center • 50,000 sever • Europa, Asia, America, Africa • T-Systems uses Cloud Computing • leverage its services delivered from data centers • aligns cloud computing with the specific requirements • rejecting cloud principles where • conflict with statutory requirements • conflict with security imperatives Presented by Majid Hajibaba 2
  3. 3. 27 April 2013 Cloud Computing: principles and paradigms - Part III 3 Enterprise ~ Cloud Computing Presented by Majid Hajibaba
  4. 4. 27 April 2013 Cloud Computing: principles and paradigms - Part III Dynamic ICT Services • Companies Challenge • need to penetrate new markets • to launch new services • to supply sales models • to make joint offerings with partners • Solution • Dynamic ICT Services (cloud) • Features • Industrialization • Standardization • Automation • Modularization • Integrated creation of ICT services Presented by Majid Hajibaba 4
  5. 5. 27 April 2013 Cloud Computing: principles and paradigms - Part III 5 IMPORTANCE OF QUALITY AND SECURITY IN CLOUDS • Quality • End-to-End SLA • Availability • Important for business • Not serious for ICT services • Weighing up risk against cost • higher service levels come at a higher price • Quality: right levels for each service NOT highest levels • Security • Compliance • Key drawback of cloud computing • legal issues (e.g., privacy and liability) Presented by Majid Hajibaba
  6. 6. 27 April 2013 Cloud Computing: principles and paradigms - Part III Dynamic Data Center • Produce Business-Ready, dynamic ICT Services • Flexibility across all modules Management with manual intervention Flexible Functional modules Adaptable Processing and storage resources Agile LAN,WAN Presented by Majid Hajibaba 6
  7. 7. 27 April 2013 Cloud Computing: principles and paradigms - Part III 7 Toward Dynamic ICT Services • Dynamic (flexible) ICT Service 1. Standardize customer’s environment • Software : single operation system • Hardware : like specific processor generation 2. Technical consolidation • Reduce servers • Reduce storages • Use identical backup/restore mechanism • Close small data center 3. Separating logical from physical • Use virtualization • Process Automation Presented by Majid Hajibaba
  8. 8. 27 April 2013 Cloud Computing: principles and paradigms - Part III Core Cloud Modules • T-Systems • Core cloud modules • Computing • Storage • Communication Presented by Majid Hajibaba 8
  9. 9. 27 April 2013 Cloud Computing: principles and paradigms - Part III Computing CMDB Role Presented by Majid Hajibaba 9
  10. 10. 27 April 2013 Cloud Computing: principles and paradigms - Part III Computing in Cloud • Advantages over conventional ICT environments • Switch customer apps. From server to server • CMDB updated automatically • Enhanced monitoring and reporting • Quality management • Resource planning • Maintain one version of each operating system • To limit number of OS’s • To minimize administrative effort • Virtualized applications • Reduce provisioning time • Quick move among servers • Update independently from OS Presented by Majid Hajibaba 10
  11. 11. 27 April 2013 Cloud Computing: principles and paradigms - Part III Storage • IP-based Storage system • use NAS, neither SAN nor DAS • Linked via Gbit Ethernet • Using fiber channel • BIS • Backup Integrated Storage • Couple backup to storage • Snapshotting • Archive • Different fire zone • Initiated from • Applications • Document management system Presented by Majid Hajibaba 11
  12. 12. 27 April 2013 Cloud Computing: principles and paradigms - Part III Storage resources Presented by Majid Hajibaba 12
  13. 13. 27 April 2013 Cloud Computing: principles and paradigms - Part III Communication • Integrate storage and computing modules • Segregate network by VPN • Customer Network • Customers : Via internet or VPN • Companies : Via unique IP address • Protected by clustered firewalls • Storage Network • A separate storage network • Accessing OS images, application and customer data • Administration Network • Segregated from all others networks • Has no access to customer’s data Presented by Majid Hajibaba 13
  14. 14. 27 April 2013 Cloud Computing: principles and paradigms - Part III Dynamic Applications for Enterprises (T-System) Enterprise Requirement • Communication and collaboration • frequent changes in user numbers • need flexible means of handling communications and collaboration • T-Systems offers two leading email systems via dynamic service • ERP and CRM • Supported by Dynamic Systems • T-Systems offer SAP and Navision • Development and Testing • Use configured systems that are not currently required • Use computing resources are no longer needed • Middleware • Platform as a Service (PaaS) • T-Systems middleware : dynamic database, web server, portal • Front-Ends and Devices • Such as Office applications • T-Systems offers via dynamic desktop service Presented by Majid Hajibaba 14
  15. 15. 27 April 2013 Cloud Computing: principles and paradigms - Part III T-Systems Case Study • Dynamic Infrastructure Service • A mid-sized furniture manufacturer • In average 1500 couches daily • Halved in summer • Outsource resource provisioning to T-Systems (use IaaS) • Scale up or down according number of users • Move at edge of technology • T-System offers private cloud • T-Systems benefit from VMware vCloud Presented by Majid Hajibaba 15
  16. 16. 27 April 2013 Cloud Computing: principles and paradigms - Part III 16 Summary • Cost and Market pressure > call increased productivity • Conventional Outsourcing • Cut cost • No flexibility • Cloud Computing • Flexibility • Straightforward relationship between providers and their customers • On demand resource • Pay per use • Outsourcing factors • Cost, flexibility, privacy, security, legislation, QoS • Solution: • Private cloud: mission-critical systems • Public cloud: non mission-critical and not require service level • Hybrid cloud: large company Presented by Majid Hajibaba
