Systems on the Edge—Your Stepping Stones into Oracle Public Cloud and the PaaS Platform [CON3122]

2

Overview

• Promises of the Cloud• Edge Systems

– What are they – attributes– Common Challenges– How can cloud help address these challenges

• Use cases and mapping to Oracle Public Cloud Services

• How to get going with edge systems in the public cloud– And pick the low hanging cloud fruit

3

Cloud Benefits

• Ease and Comfort• Cost effective• Flexibility – quick, agile• Quality• Security• Any time, Any place

4

Why is the cloud hot?

• Web Scale for the rest of us– Availability, Scalability, Security, …

• No specific expertise or even effort for consuming services– No need to acquire skills, build up experience and hire special resources

• No physical facilities – room, cooling, cleaning, physical security, power

• No/Low initial investment (low entry level)• Pay per use (no gain, no pain) (CAPEX => OPEX)• Flexible up and down scaling (capacity on demand)• Quick Ramp-Up, Rapid Start• Enterprise functionality for small businesses

– Out of reach in the on premises world• Accessibility from anywhere• Global market place • Lifting the burden from your shoulders

How to get to the cloud?

• Well, that is not the question we will address in this session• It is a bottom up approach, thinking from current systems

– We will get there - eventually

Edge Systems

• What are edge systems?– Systems accessed by parties (people

or systems) from outside the enterprise • Typical characteristics

– Visible to business partners & the general public– Interactions initiated externally – large numbers of

unknown individuals/devices/systems• External entities accessing systems

– Uses data only indirectly (does not store data)• Except application specific data and perhaps for caching reasons

Edge Systems

• Typical Challenges– High availability requirements– Scalability/volume/peaks

• License consequences

– Latency– Security: potentially large numbers of fairly

unknown parties accessing the enterprise realm– Provisioning environments and network

configuration (timely)

How cloud addresses challenges for edge systems

• High availability requirements– Web Scale operations– Multi-site (region)

• Scalability/volume/peaks– Dynamic, rapid, on-demand upscaling/downscaling– Pay per use, no upfront investment

• Latency– Multi Data Center topology, Distributed Content Delivery

• Security: potentially large numbers of fairly unknown parties accessing the enterprise realm– Relocation of the DMZ to the cloud– The only interaction with the enterprise realm is by well-known cloud based systems

– not by many third parties– Web Scale security measures

• Provisioning environments and network configuration– Out of the box, click-next-finish, minutes to completion

16

Edge on Cloud <=> On Premises integration challenges

• Data Pipe– Two way (cloud enterprise)– Synchronous & Asynchronous (event push)– Secure– Approach: SSH or even VPN channel, API Gateway in DMZ, local agent on

premises, leverage message cloud (aysnchronous push and pull)• Data Cache (refresh) & Data Replication• Identity Management – replication of identities & roles• UI Integration

– “mash up” and deeplink navigation– Session sharing and Single Sign On– consolidated search and menu– style & web content synchronization

• Software Delivery – (no more challenging than on site)

18

Case:Monthly Reporting obligation

• Financial institution is faced with the requirement to monthly report events and status to a dozen stakeholders such as government agencies– Each stakeholder receives a customized report

• The challenge: how to deliver the report– Given functional and non-functional requirements

• Options– On paper– Email attachment– (S)FTP server– Read only secure web site– …

• Requirements– Electronic, On line– Archive/history– Searchable– Multi-format

CustomerCustomer


• Developing an application for long term project budget management– Especially for local and regional governments

• Implemented on premises– Done by technical implementation consultants that go on site with customer– Challenging to get servers, network, database => long implementation times

• Objective: – Offer the product to smaller

organizations (increase reach)

– Offer the product in the global market place

• Requirement:– Very rapid implementation

- (turn key == enter URL) without on site consultancy

– Global accessibility– Flexible capacity

• Replace custom or COTS applicationon premises with SaaS offering– More functionality, less effort,

easier admin & maintenance,work anytime any place

– Note: SaaS == Silo as a Service• Move custom or COTS

application from on premises to PaaS – Easier admin & maintenance, better

scaling (up and down), work anytime any place

• Challenges– Existing integrations – both API– UI Mash-up– Single Sign On (and IAM)– Data replication & governance

Case: the ultimate digital user experience

31


• Pension Fund with high ambitions– Themes: Digital, self service, 24/7, paperless, STP , Google fast and Apple friendly– User benefits: higher quality and faster (even pro active) response, great experience– Business benefits: cost reduction, competitive position, new services, agile: quick time

to market• Portal and Customer Experience are crucial in this strategy

– Multiple user groups (employees, employers, financial consultants, …– Multiple brands– Both public (web site) and personal (authenticated portal)– Strong integration with back end enterprise systems– Easy web content management (dialogs, documents, FAQ/knowledge, events& news)– End to end “interaction & process analytics”– Security and compliancy regulations– Multi-channel strategy: portal and B2B are main channels – but not the only ones

(telephone, chat, social, email and for now paper based mail); perhaps mobile as well• Traditionally, most applications are custom built with Oracle technology and

deployed on-premises

Case: IoT

• Collect physical measurements and signals from the real world in real time– Security Sensors, Traffic Flow Signals,

Biomedical Measurements, Weather Conditions, Earth-Movement-Registration, Logistics Recordings,

• Gather, Filter, Analyze, Process signals to data, information and findings

• Challenges:– Availability – real time, 24/7, quick reaction required (sometimes, but very quick)– Accessibility (from many different locations, many outside enterprise reach)– Volume (and real time peak capacity)– Latency (local data drop-off points and decentralized initial processing)

• Conditions– Limited (initial) enrichment– Eventual hand-over of findings to enterprise infrastructure and systems

How to get going with an Edge System on the cloud

• Create an Oracle Public Cloud account + Identity Domain• Subscribe to relevant Cloud Services

– Configure these services to (be able to) work together (associations within identity domain)

• Manage users within identity domain plus service access privileges

40

• Perform development locally (for most cloud services)– ICS, PCS, ABCS and MCS have development through the browser in the cloud– Optionally use the Developer Cloud Service to organize (distributed) development

• Implement automated build and deployment to the cloud (Cloud targeted CD), possibly using Oracle Developer Cloud Service

• All testing is done in the cloud– unit test, system integration test, acceptance test, automated regression test

42


• Implement the bridge between (API calls, navigate/deeplink, UI mash up)– the various cloud services– the final cloud services and the on-premises systems– Also: network configuration to support the bridge

• Arrange for user friendly URLs – for end user User Interface systems• Implement Identity & Access Management for internal and external users

– Integrate with on-premises IAM systems (replicate to cloud?)– Single Sign On across cloud and from on premises to cloud

• Set up Cloud Ops – Operations for the cloud based systems & flows – Oracle Management Cloud

43

Summary

• Do not ask: how to get to the cloud• Starting point is why?

Cloud fulfills a business need or provides a business opportunity – That is the driver and the business case justification

• Edge systems have common requirements, challenges and opportunities– Many of which are dealt with by cloud based solutions– The business case is quickly defined – using speed, capacity, flexibility, availability,

security, functionality and TCO• Typical edge systems use cases include:

– B2B, Portal, Mobility, Silo-as-a-service (lift and shift)• Other low hanging cloud fruit

– Development automation, Back up, Long term archive, Monitoring (real time analytics on log files and operational metrics), BI and Tactical Analytics

• An initial investment is required: time, effort, frustration, learning curve– Opportunity to be an early adopter and reap benefits quickly
