Definitions: On-Premises, Off-Premises, In-The-Cloud

• On-premises: Software is installed and runs on servers in a building, i.e., at a clientOff premises: Often refers to hosted software scenarios • Off-premises: Often refers to hosted software scenarios

• Type of cloud services: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)

• Public cloud: Public accessible cloud service, i.e., Amazon where the user usually does not know where software is physically runP i t l d Cl d i i t ll d i i t • Private cloud: Cloud services are installed on-premise, i.e., at a client and is only accessible internally to the cloud provider, i.e., the client (service consumer)( )

• External private cloud: Secured cloud services provided by a cloud provider dedicated to a client

SAP Imaging and Archiving

• SAP offers integration to archiving solutions through its SAP ArchiveLink and SAP NetWeaver® Information Lifecycle Management interfacesManagement interfaces

SAP ArchiveLink interface: HTTP/S based communication to control documents on compliant repositoriesSAP ILM/BC-ILM 2.0 (WebDAV) interface: Web-based distributed authoring and versioning

SAP ArchiveLink is currently the most commonly used protocol to • SAP ArchiveLink is currently the most commonly used protocol to store scanned or other electronic images connected to SAP

• SAP ILM/BC-ILM 2.0 is relatively new and used in connection with ySAP NetWeaver® Information Lifecycle Management

Risks and Benefits

• Common concerns are:Data integrity (no one is tampering with it)

A hit t d fi d tArchitecture defines secured storageData consistency (SAP data in sync with archive)

Content Server and Link Tables define mapping of SAP Content Server and Link Tables define mapping of SAP transactional data to electronic documents in the archive

Rigorous compliance (retention, security, and availability)Compliance software layer ensures retentionUptime and availability through SLAs

Unification of business process (seamless integration)Business process not interrupted due to SAP’s existing system designsystem design

16

Benefits of Cloud Services

• Higher availabilityDedicated environments guarantee high availability rates

B tt l bilit• Better scalabilityAs you grow, the service grows

• Lower costs• Lower costsBetter pricing on storage and server capacity

• Less complexityp yElimination of a whole set of infrastructure

• Improved elasticityRetrieval power is provided when you need it

• Higher agilityWh d it b ib d l iWhen you need it, subscribe and plug-in

17

Key Benefits of Cloud-Based Computing

• Cloud Computing for SAP archiving allows:… Consuming Archiving-as-a-Service

S i i i i d d … Service provisioning on-demand … Rapid deployment to accelerate business projects

Managing cost w/ flat pricing models like pay-as-you-go… Managing cost w/ flat pricing models like pay-as-you-go… Standardized “custom” deployments… Scalability due to dynamic resources provisioningy y p g… Flexibility (elasticity) to the customer’s business needs… Efficiency due to better utilization… Agility due to subscription model and adaptability

How Does It Work?

How Does It Work? (cont.)

• Service ProviderEncapsulated document/archiving software solution S i ff i f th l t d ft i Service offering of the encapsulated software-as-a-service (SaaS)

• Client/ConsumerSubscribe and consume it as a service (SOA)

Configure https support at the client siteConfigure document management/data archiving in the li t’ SAP tclient’s SAP system

Instantly use it and be compliantInstantly exit and be in controlInstantly exit and be in control

Pricing Models

• On-premiseTypically fully licensed software by client/consumer which is installed locally and

Under internal administration, orUnder outsourced administration

Off premise (cloud: SaaS)• Off-premise (cloud: SaaS)Software and administration are offered as a serviceNo license and maintenance fees are dueNo license and maintenance fees are dueSoftware is owned by service provider and offered for consumption based on a monthly service fee

27

Hosting and Cloud Computing Examples

• Many customers run SAP and their archive solutions in a hosted cloud environment

• Example ALarge consumer goods company

Centralized archive servers and storage for users worldwideFully hosted scenario in an external private cloudFully hosted scenario in an external private cloudSavings over $1.5m annually

• Example BL b d di t Large beverage and condiments company

Centralized archive servers and storage for users with two data centers

One in Canada for North America and EuropeOne in Singapore for all of Asia (due to bandwidth)

Significant savings through worldwide consolidationg g g

Business Case

• Based on one SAP system and 1 terabyte of data $114,000in secured storage savings

over 5yrs!

What About Transitioning? (cont.)

• Legacy documents and data uploadingEffective migration proceduresE t l t l d i tExternal access to cloud environments

• Business processes should be fairly untouched• Technology that makes moving easier• Technology, that makes moving easier

APIs and interfaces give direct access Extract your data at any time

32

Cloud Services Are Not for Everyone!

• How could this work for me?• Answer the following questions: How could we be harmed …

If th t b id l bli d id l di t ib t d?If the asset became widely public and widely distributed?If an employee of our cloud provider accessed the asset?If the process or function were manipulated by an outsider?If the process or function were manipulated by an outsider?If the process or function failed to provide expected results?If the information/data were unexpectedly changed?p y gIf the asset were unavailable for a period of time?

• … and then structure your cloud solution to safeguard against these concerns

33

Service Level Agreements and Other Considerations

• The following should be clearly regulated in your SLA and legal agreements:

The right to retain ownership use and control of one’s dataThe right to retain ownership, use, and control of one s dataThe right to an SLA that addresses liabilities, remedies, and business outcomes: The agreement should comprehensively dd th b i i i li daddress the business issues implied

The right to notification and choice about changes to the consumer’s business process (upgrades, changes to the p ( pg , gprocess)The right to understand the technical limitations or requirements of the service upfrontrequirements of the service upfrontThe right to understand which jurisdiction the provider operates inThe right to know which security processes the provider follows

34

What to Consider …

• Pre-negotiate exit fees• Contractually define an exit strategy

A th ff t t it f t• Assess the efforts to exit upfront• Mitigate the risk of a lock-in

• The good and the bad (examples):Open source: Standard transition interfacepClosed application: No data interfaces available

7 Key Points to Take Home

• Adding business value is most important• Focus on your key business differentiators, consider purchasing

IT services instead of acquiring and managing the infrastructure IT services instead of acquiring and managing the infrastructure • Cloud services allow you to utilize business benefits much faster

compared to owning an on-premise software solution• Choose the implementation which is right for your business:

cloud (SaaS) vs. on-premiseC t t SLA ith l d i id• Create strong SLAs with your cloud service provider

• Conduct a comprehensive risk/benefits analysis• Evaluate your situation and decide what works best for you• Evaluate your situation and decide what works best for you
