Oracle announcing Oracle Public Cloud – First comments.

I am at S.F. at the Oracle Open World conference right now where Larry Ellison announced the Oracle Public Cloud in an entertaining and rather fun presentation just an hour ago. To see some more photos of the event and my paparazzi shot of Sting who already showed up for some 30 seconds: check out the Facebook site of my Oracle Cloud Computing book.

Larry picked up many ideas that I published earlier this year in my cloud computing book:

He was talking a lot about migrating from one cloud to another (mostly using AWS as an example, so they seem to be on the friend list). Also he emphasized that simple multi-tenant SaaS offers such as with a shared DB are not real clouds and risky (because of the shared DB 🙂 ).

When Oracle’s position about clouds was rather fluffy (should I say cloudy?) even one year ago, I now hear them talking more about elasticity, self-service, chargeback etc.

What I didn’t like: So far this does not include pay-per use yet (one of my 4 criteria of cloud computing). Larry mentioned a monthly subscription during his keynote which was confirmed in the Thu morning keynote. Yet Oracle Enterprise Manger 12c is announced to provide metering at various levels.

I will post an update here as soon as there will be more details out tomorrow.

Apart from announcing the Oracle Public Cloud also Oracle Social Media (a part of Fusion Applications) was announced. See fotos on Facebook.

Oracle Fusion Middleware and AWS Cloud Services

Sydney Conference Center

I yesterday gave a presentation at InSync2011 about Oracle’s cloud computing strategy, AWS cloud services and it’s current limitations. Amazon reacted quickly and updated their offering. We have been waiting for that. Keep going!

AWS outage destroys EBS-based AMIs in Europe region

I always recommend to create your own EBS-based AMIs (e.g. for running complex software such as Oracle Fusion Middleware). This hold true for the classic AMIs as well as for the converted Oracle VM templates. Never rely on the existence of AMIs provided by Oracle because:

– Oracle can change or update (or remove) them any time.

– They often don’t exist for certain AWS regions, they are S3-based or only exist based on 32-bit OEL instead of 64-bit.

– Also, the AMIs provided often don’t exist for a specific version of Oracle products.

So always create your own copy! Yet here is something to consider:

AWS broke an EBS-based AMI of mine by deleting arbitrary block in the image. This is particularly annoying since there is no easy way to create an offline copy an EBS-based AMI. You could rsync the running image to local computer but there is absolutely no support to get this done in a user-friendly way from the AWS console.

The good: They informed me in time (being in Sydney if something happens in the EU regions gives you an advantage) and sent an apology. They also replaced the deleted blocks with empty blocks.

The bad: It cost me several days to create this AMI which was an OEL EBS-based, full-blown installation of Oracle SOA Suite (I still have to check if it will be usable after a file system check).

For a more detailed explanation of what happened take a look at Amazon’s summary of the events. It summarizes to an error in the EBS software that was overlayed with a power outage in Dublin.

Hello Amazon: Why don’t you provide an easy way to have an offline backup of EBS-based AMIs for disaster recovery?

WebLogic JMS with SAF and JMS bridges or SQS : Legacy Integration in the Cloud with Oracle WebLogic, WebSphere and OSB / Apache Camel

An interesting question popped up on my Oracle Middleware and Cloud Computing book site which I like to answer here for the benefits of all the others puzzling at similar integration questions. In the context of using JMS as an integration technology I’d like to summarize the usage scenarios for Oracle WebLogic JMS Store-and-Forward and JMS-bridges (both are included in WebLogic server).

Hi Frank – [ …] We have a requirement to build 2-way asynchronous integration between an application running on WLS in AWS and a legacy J2EE app running on IBM WebSphere in our Data Centre. From your excepts my understanding is that SQS is intended for use only between AWS apps – is this correct ? I think we need to be looking at a full JMS solution for our integration – perhaps using WLS JMS Store-And-Forward – Thanks, Peter D

Hi Peter,

Based on your comment I cannot go into great detail or even provide a solid architecture that anwsers you question (one that will save you from more reading) but here are some important points to consider:

– Amazon’s SQS is not restricted to be only used from AWS instances. SQS is purely based on web services (or language bindings that encapsulate those WS calls) so you can use it from any computer. E.g. you can read or write to SQS queues from remote.

WLS Store-and-Forward (SAF) can only couple WLS instances of the same version and does not bridge to other JMS providers. You cannot use SAF to transfer from WLS JMS to IBM MQSeries (or whatever Websphere might use). JMS is a pretty bad integration technology which requires to have the right messaging classes in your classpath. E.g. when writing messages from Websphere to a WebLogic JMS queue you are required to have the WLS JMS classes in Websphere classpath.

–  You can use the WebLogic’s JMS bridge to solve the somehow messy classpath issues. WLS JMS bridge has to be deployed as JCA adapter (still the jar file from the other provider is required but it is not used in custom code). The bridge will automatically forward from e.g. WLS JMS to MQSeries and even supports transcations. However there is no support to bridge between WLS JMS and AWS SQS.

– Unlike let’s say Oracle Service Bus, if you are looking at Apache Camel there is support to convert incoming JMS messages to outgoing SQS. Note to Oracle’s product manager of OSB: we would appreciate to have SQS as a supported transport protocol or possibly as an SOA Suite JCA adapter. Thanks for considering it 🙂



Ebook Released: Middleware and Cloud Computing











After a couple of fun days playing with (mostly disastrous) tools, converters and the Kindle itself I published the first Kindle edition of “Middleware and Cloud Computing”. It contains more than 100 coloured graphics (well, of course they are not coloured on your b/w Kindle, but on the Kindle reader for your Mac, PC, Android, iPad etc) and more than 100 clickable links to additional resources, publications and tools.

Please spread the word, twitter it to the networked part of the known universe and don’t forget to LIKE its Amazon and Facebook site. Do you you really, really want to support it? Sincerely? The best you could do is writing a review once you have read it.


thanks and best wishes,
