Businessreasons– Whymoveto the cloud ?
Major driving forces behind utilities transformation
Erosion of old business models means that utilities are looking for:
• new business models, • cutting costs, • improving customer service, • more outward orientation – ability to integrate 3rd parties
IT Challenge – how to support the company within this change
Long term IT strategy to support utility transformation drives cloud adoption
• internal RWE goal: implement long term IT strategy ≈„Commodity IT versus differentiating IT“ & “Manage IT –not make IT”
• get resource flexibility, lean capacity management andstandardize risk, security management and BCMprocesses “out of the box”
• support business leveraging IT market trends & newdevelopment
Business expectations
• improve time to market for IT solutions
• cut operating costs and redirect savings into development in prospective areas
• compete in digital area - raisematurity level of RWE IT solutions
• provide future-oriented IT solutionswith respect to investment/disinvestment
• avoid technological lock-in – clear exit strategy (“Infrastructure as a Code”)
• avoid brand impact due to security & data privacy issues
Considering Cloud Pros and Cons
• Fast availability of resources –agility, scalability (up/down), “infra as code”
• Simplification of support processes (BCM, audit, energy mgmt., HR, innovation, …)
• Standardization of data security (requirements, measures and operating model)
• Cost and usage transparency
• Enforcing interoperability and best practice in application design (de-facto standard)
• Concerns around Data Privacy, Data security and BCM due to loss of the physical proximity
• Dependency on innovation cycle of the cloud provider
• Lack of “best practice” becomes visible due to speed of deployment (in lifecycle mgmt., IT architecture and documentation)
• Little space for custom tailored solutions
• In utilities environment CAPEX might be pushed by „traditionalist“ regulators

UseCase– SAPHRinAWS
Businessreasons– Whymoveto the cloud ?
Use Case SAP HR: Fallback planWe have designed two fallback scenarios for SAP HRP migration to AWS.• Imminent Fallback - when productive migration is performed, on-premise servers and SAP
installation remain intact and in case of negative test results prior to productive go-live on AWS.SAP Solution is started back on-premise without any particular delay.
• AfterGo-LiveFallback - on-premise installationisshutdown Itisnotpossibletostartbackon-premise SAPsolution becauseofchangesonOracle DB.Onlywaytogetthesechangesintoon-premise AIXOracleDBwouldbeexportonAWSandimportbacktoon-premise DB.Thiswouldbeverytimeconsuming.Aftergo-liveregularbackupoperationisput inplaceonAWSsoOracleDBisbackeduptoS3.On-premiseweprepareIntelinfrastructuresimilartoAWSwithOracleonLinux,forcompletenessalsocurrentAIXDBisdepicted.In case of fallback, we restore Oracle S3 backup into on-premise Oracle DB on linux and start on-premise SAP Solution with newly restored latest data.
Use Case SAP HR: Business feedback
• Improved performance of system within the fast close period (inc. fix time), capacity “ondemand” to cover the peaks
• Economic benefits – savings cca. 10 - 12% against on-premises solution
• Ability to switch on/off e.g. testing environment – pay for what you consume - utilization ofHW is not the topic of heated discussions and cumbersome planning & logistics proceduresanymore
• Data security level improved – volume and DB are encrypted
Leassons learned• Apps profiling key to help collect all information for services to be operated – internalhygiene
• Cloudification improved service delivery maturity level and pushed understanding keydrivers of the services
• Helps to increase know–how of IT apps team, attractive for external developers – visibleimpact to team spirit & productivity
• Build strong engineering cloud „crazy“ team – combine internal and external
• Develop internal skills with external partner who has a proven project methodology
