#OOW2013: Jump into the Cloud...

Today we went into the Cloud, with 3 major announcements delivered by Thomas Kurian: a full Database as a Service, a full Java as a Service and a full Infrastructure as a Service in Oracle Cloud, guaranteed, backup and operated by Oracle, depending on different level of services.

Database as a Service

You will be able to provision inside Oracle Cloud a full Oracle Database (12c or 11g) either in single node or in highly available RAC cluster. This Database will be accessible in full SQL*NET, with Root access. This service will be offer in 3 different models :

Basic Service: pre-configured, automatically installed Database Software, managed by you through Enterprise Manager Express.

Managed Service: Oracle Databases managed by Oracle, including :

  • Quarterly Patching and Upgrades with SLA
  • Automated Backup and Point-in-Time Recovery
  • Elastic Compute and Storage

Maximum Availability Service: Oracle manages an highly available Database, including:

  • Real Application Cluster (RAC)
  • Data Guard for Maximum Availability
  • More flexible upgrade schedule

Of course you will be able to move your Data or even you entire Database between your Enterprise Datacenter and Oracle Cloud by leveraging regular tools like SQL loader or Data Pump for example.

Java as a Service

In the same model as the Database as a Service, you will be able to deploy dedicated Weblogic cluster(s) on our Compute Service. Full WLST, JMX and Root access will be provided as well. The 3 different models of services will be the following:

Basic Service: pre-configured, automatically installed weblogic software, with a single node Weblogic Suite (12c or 11g), managed by you using Enterprise Manager.

Managed Service: Oracle manages one or more Weblogic domains in the same way as the Database as a Service's Managed Service.

Maximum Availability Service: Oracle Manage an Highly Available environment, with the following characteristics :

  • Weblogic cluster integrated with RAC
  • Automated Disaster Recovery and Failover
  • More flexible upgrade schedules
  • Additional staging environment

So now let's have a quick look at the constituents of our Infrastructure as a Service layer.

Infrastructure as a Service

Compute Service: will provide an elastic compute capacity in Oracle Cloud, based on 3 different type of requirements : Standard, Compute Intensive or Memory Intensive. The management will be based on REST API, and providing as well Root VM access. This Compute Service will provide network isolation and elastic IP addresses. And of course, it will be highly available.

Storage Service: will store and manage digital content. The management will be through Java and REST API (OpenStack Swift). It has been designed for performance, scalability and availability.

 All those new or enhanced services, are complementing all the Oracle Software as a Services already existing and adopted with success by many of our customers, like was shown in many testimonies during Thomas Key Notes. This provides a Platform for our partners who are leveraging our technologies to build their own services in Oracle Cloud. That's why we also created an Oracle Cloud Market Place, enabling the delivery of our partners applications, as well as their combination/integration tailor to your specific needs directly in Oracle Cloud.

Let's Jump into the Cloud....

Oracle VM virtualization on T4-4 : architecture and service catalog

Last Tuesday, during the SPARC Showcase event, Jean-François Charpentier, François Napoleoni and Sébastien Flourac delivered very interesting uses cases of deployment of latest Oracle Systems at work : Oracle VM virtualization project on T4-4, intensive financial trading on T5-2 and a complete Information System migration to Oracle SuperCluster.

I will start to cover in this post the main points that Jean-François Charpentier focus on to build a consolidated T4-4 platform, effective for his Business users.

Oracle VM virtualization on T4-4 Architecture

As often, Mr Charpentier had to handle existing environment, that needed to be taken into account when building this new virtual platform. First he had to be able to provide a platform that could consolidate all the existing environments, the main driver here being :

  • total memory requirement of existing asset
  • multi-tenant capability to share the platform securely between several different networks
  • comply to strong SLA

T4-4 was the best building block to cover them :

  • memory : up to 2 TB
  • multiple networks connection : up to 16x PCIe extension
  • Oracle VM built-in with redundant channels capability and live migration
  • Solaris binary compatibility to enable easy consolidation of existing environments

Overall Architecture Design

The deployment choice have been to setup 2x Oracle VM T4-4 clusters per sites as follow:


To cover his SLA requirements, Mr Charpentier built redundancy not only by providing multiple T4-4 nodes per Oracle VM clusters, but also at the Oracle VM itselfs. For Oracle VM, he chose to make redundant storage and network virtual access layer as display in the following 2 diagrams.

Oracle VM Virtual Mutlipathing with alternate I/O Domain


Oracle VM Virtual Network Access through IPMP


 All of this virtual network layer being link to different network back-bones, thanks to the 16x PCIe extension of the T4-4, as illustrated in the following diagram.


Another option could have been to deploy Oracle Virtual Network, to enable the disk and network access with only 2x PCIe slots at the server layer.

Oracle VM on T4-4 Service Catalog

Beside the architecture choice, that needs to comply with strong SLA. The development of a service catalogue is also very key to bring the IT toward a service provider. And it is exactly what have been put in place by Jean-François Charpentier, as follow :

 By putting in place this new virtual platform with its associated service catalog, Mr Charpentier was able to provide to his Business better agility thanks to easier and faster deployment. This platform has become the standard for all Solaris deployment for his business unit, and they expect to reach a 90% to 100% Solaris virtualization by 2014.
