Artikel: Oracle WebLogic Server und Fusion Middleware in der Cloud

German only. Heute exklusiv auf deutsch ein Artikel den ich für das DOAG Magazin im Früjahr 2011 geschrieben habe:
Download: Oracle Fusion Middleware und WebLogic Server in der Cloud (PDF)

  • Cloud Dienste oder Fusion Middleware Features?
  • Was zeichnet eine echte Cloud aus?
  • Architektur Blueprint für die AWS Cloud und Java EE Anwendungen.

Teile des Artikels sowie zahlreiche Grafiken sind aus meinem “Middleware and Cloud Computing” entommen. Viel Spaß beim Lesen!

Usage of Oracle Exadata, Exalogic, Oracle Fusion Middleware and Enterprise Manager within Oracle

Oracle is eating its own dog food.

Here is an interesting slide set from OOW11 about how Oracle is using it’s own hardware and software.

Still a lot of Oracle appserver to see instead of WebLogic..

2-day Amazon AWS Cloud Computing Workshop / Training Course

For an updated version of this workshop see here or contact me directly.

I’ll be offering a 2-day cloud computing workshop 2+3. May 2011 in city center of Munich. A second event is planned for Sydney later this year and will be announced by the Australian Oracle User Group.

After a basic introduction and the discussion of common misconceptions we will cover advanced topics such as how to achieve true elasticity, load balancing in clouds, queueing, notifications and databases in clouds. This workshop is centered around Amazon Web Services (AWS) technologies such as EC2 EBS images, RDS, SQS, SNS, ELB etc.

The workshop includes a free copy of my Middleware and Cloud Computing book, printed course material, a pre-configured lab environment to take home as a virtual image on DVD.

Please contact me via email for registration and further details.

AWS Relational Database Service (RDS): Read Replicas & Multi-AZ Instances

Friday morning. Second cup of coffee. I remember the discussion I had yesterday about the differences of RDS read replicas vs. multi-AZ instances in the Amazon compute cloud.

Actually these concepts are completely different. So it is important to pick the right one that supports your design. Here is a short comparison:

Multi-availability zone instances Read replicas
Purpose Availability Scalability
Number of copies 1 primary + 1 secondary 1 primary + n secondaries
Secondaries used during normal operation? No Yes
Synchronization Synchronous Asynchronous
Use with ELB No (only one active) Not supported
Use with elastic IPs Not supported Not supported
Cost Doubles Per Instance

And don’t forget you can use a combination of both.
