Impact of Cloud Services on the work of Oracle technology experts?

Bio – Andreas

Chatziantoniou• Freelance Oracle Fusion Middleware

Consultant• 17 years Oracle experience/27 years

IT (Unix/C) • Oracle ACE• andreas@foxglove-it.nl

Agenda• Where are we now?• Roadmap– Trial runs– Learn–Use

• Conclusion

Show of hands

DBA’s• Who is a DBA and takes care of the

day-to-day operations and technical aspects of the Database?– Create a DB– Patching– Performance–Housekeeping– Support developers– And so on …

Fusion Middleware/WLS • Who is a FMW Admin and takes care of

the day-to-day operations and technical aspects of the Application Server, J2EE, FMW?– Create Domains– Patching– Performance–Housekeeping– Support developers– And so on …

Infrastructure• Who of you is also responsible for

these fancy topics:– Operating System– Storage–Network (Router, Firewall, etc.)– Everything else that smells like

technology

We are history

Where are we now?• For many years Oracle, our employers

and the market (customers) expected that we knew every tiny detail of the Oracle Productstack

• We delivered– Yeah – we are the EXPERTS!

• Problem–We are too expensive, to slow, not scalable,

want holidays and have our own opinion, …

Will the status quo remain?

• Costs pushes customers into the Cloud

• Time-to-market pushes customers into the Cloud

• Scalability pushes customers into the Cloud

• Technology (complexity) pushes customers into the Cloud

Roadmap• In the years to come a large part of our

current activities will be delivered by Oracle and other service providers – This will happen in the Cloud

• Which activities will remain that we can carry out?

• Where and how will we work in the future? • What do we need to learn and which skills

will the customer require in the future?

Roadmap (2)• Cloud – trial runs• Cloud - learn• Cloud - use

Will it be a walk in the park?

Back-roads(Cul-de-sac?)

Back-roads – Engineered Systems

• How about Exadata, Exalogic, Oracle Database Appliance?– Exa* are good starting points for IaaS,

PaaS, DBaaS– Virtualization– Standardization comes naturally

Back-road – Engineered Systems (2)

• Private Cloud as a start for a migration towards the Cloud– Exa* != Oracle Cloud Services– Exa* = Engineered Systems • It has its own technology

– Oracle Cloud Service = Oracle VM++

Back-roads –Engineered Systems (3)

• Exadata meant a stiff learning curve for the classic DBA (primarily focused on operations)

• Exalogic and Fusion Middleware brought networkadministration to the table

Cul-de-sac• Pretend as if the world does not

change• Pretend that the own company is

unique–Worldwide only very few really are!

• Pretend as if the migration is too complex

• Remember Cobol?

From Exa* into the Cloud

• Exa* offers (partially) the same technology as the Cloud

• Networkconfiguration

Cloud trial runs• Who tried the Cloud already?

Cloud trial runs (2)

Cloud trial runs (3)• At this point in time there are 16

publically accessible Cloud Services that can be tested for free

• For Oracle Partner (Gold and higher) there are even more possibilities

Cloud trial runs (4)• Start with DBaaS – 11g or 12c– SE1, EE, EE High Performance– Do it yourself or let Oracle do the job– SQL*NET, root access, Enterprise Manager,

all DBMS tools – Portable – on-premises & cloud

• Use Case: Dev/Test and “lift & shift” DB applications into the Oracle Cloud

Cloud trial runs (5)• Database Schema Service – Own Schema– Fully managed service – Application Development: • APEX, SQL Developer, Java, RESTful Web

Services • Use Case: Extensions for Oracle

Cloud SaaS applications

Cloud trial runs (6)• Java Cloud Service – Own WLS (cluster) including root

access –HA, on-demand DR – Can be modified for all Java applications

• Use Case: “Lift & shift” WebLogic and other Java applications into the Oracle Cloud

Cloud trial runs (7)• Java Cloud Service – SaaS

Extension – Pre-configured WebLogic VM for faster

application deployment – Built-in Integration for Storage, Messaging– JDeveloper, Eclipse, Netbeans for

development • Use Case: Extend Java EE SaaS

applications

Cloud learning• For Oracle Partners a number of

trainings are available– http://partners.oracle.com

• Developers– https://cloud.oracle.com/en_US/paas_su

pport• Customers– Almost everything on http://oracle.com

Cloud learning (2)• Partner: – Certification (specialization) is partially

available– Lot’s of information for Sales–WebLogic / SOA Suite community–Marketplace

Cloud learning (3)• Developers:– Download Training

Cloud learning (4)• Oracle Learning Library

Cloud learning (5)• Oracle‘s Cloud Stack is growing

rapidly– Is it useful to limit one‘s Cloud Service

exposure?• This could take place alongside the

classic product lines (tech) or Business products

Cloud use• Before moving into the Cloud it

becomes necessary to figure out which Cloud Services are right for me

• Current offerings are almost overwhelming– In addition there are subsets of Virtual

Images, real Cloudsolutions or in-betweenies

Cloud use (2)• Management and Technology– Aren‘t those topics solved already by the

Cloud?–Nothing is less true!

• How can my current applications that remain on-premises work with Cloud applications?

• How about user management?• Network– VPN, Tunnel, etc.

Cloud use (3)• Who is doing what?– Oracle or your own organization?– SLA must still be honored– Backup & Recovery• Backup of the Cloud ;-)

Cloud use (4)• The Cloud should relieve me of most/all

admin activities– How much is the Cloud provider doing?

Contracts?• Expectation is that there is still a need

(albeit limited) for a local DBA• If you start with a Virtual Image (often in

Java Cloud Services) then the Fusion Middleware Administrator will probably do the same as before

Cloud use (5)• Hybrid Systems–No customer will go to the Cloud with a

Big Bang– Small baby-steps with smaller systems

and the bulk remains on premises– This will have a big impact on the work

of the Oracle administrators

Conslusion• Future of Oracle Technologyexperts• Near future will bring a huge playing

field for us (combinations are possible)–Work at a Cloud Provider– Focus on Private Clouds– Support hybrid environments– Consulting on Cloud services– (Cloud) Softwaredevelopment

What is the Cloud?

… meaning• Problems won’t go away– They just move to a different place

• Whenever Oracle says everything will become easier more work for us
