Oracle’s data integration product landscape outside of GoldenGate has with the arrival of Oracle Cloud been confusing at times. This has meant finding the right product documentation can be challenging, and knowing which product to use in your own technology road-map can be harder to formulate. I believe the landscape is starting to settle now. But to understand the position, let’s look at the causes of disturbance and the changes that have occurred.
Why the complexity?
This has come from I think a couple of key factors. The organizational challenges triggered by Thomas Kurian’s departure which has resulted in rather than the product organization being essentially in three parts aligning roughly to Infrastructure, Platform and Applications to being two Infrastructure and Apps. Add to this Oracle’s cloud has gone through two revolutions. Generation 1 now called Classic was essentially a recognition that they needed an answer to Microsoft, Google and AWS quickly (Oracle are now migrating customers off classic). Then came Generation 2, which is a more considered strategy which is leveraging not just the lowest level stack of virtualization (network and compute), but driving changes all the way through the internals of applications by having them leverage common technologies such as microservices along with a raft of software services such as monitoring, logging, metering, events, notifications, FaaS and so on. Essentially all the services they offer are also integral to their own offerings. The nice thing about Gen2 is you can see a strong alignment to CNCF (Cloud Native Compute Foundation) along with other open public standards (formal or de-facto such as Microprofile with Helidon and Apache). As a result despite the perceptions of Oracle, modern apps are standard a better chance of portability.
Impact on ODI
Oracle’s Data Integration capabilities, cloud or otherwise have been best known as Oracle Data Integrator or ODI. The original ODI was the data equivelent of SOA Suite implementing Extract Load Transform (ELT) rather than ETL as it meant the Oracle DB was fully leveraged. This was built on the WebLogic server.
Along Came Cloud
Oracle cloud came along, and there is a natural need for ODI capabilities. Like SOA Suite, the first evolution was to provide ODI Cloud Service just like SOA Suite had SOA Cloud Service. Both are essentially the same on-premises product with UIs to manage deployment and configuration.
ODI’s cloud transformation for the cloud lead ODI CS evolving into DIPC (Data Integration Platform Cloud). Very much an evolution, but with a more web centered experience for designing the integrations. However, DIPC is no longer available (except possible to customers already using it).
Whilst DIPC had been evolving the requirement to continue with on-premises ODI capabilities is needed. Whilst we don’t know for sure, we can speculate that there was divergent development happening creating overhead as ODI as an on-prem solution remained. We then saw the arrival of ODI Marketplace, this provides an easier transition, including taking into account licensing considerations. DIPC has been superseded by ODI Marketplace.
Oracle has developed a Marketplace just like the other major players so that 3rd party vendors could offer their technologies on the Oracle cloud, just as you can with Azure and AWS. But Oracle have also exploited it to offer their traditional products normally associated with on-premise deployments in the cloud. As a result we saw ODI Marketplace. A smart move as it offers the possibility of exploiting on-prem licensing into the cloud along with portability.
So far the ODI capabilities in its different forms continued to leverage its WebLogic foundations. But by this time the Gen2 Oracle Cloud and the organizational structures behind it has been well established, and working up the value stack. Those products in the middleware space have been impacted by both the technology strategies and organization. As a result API for example have been aligned to the OCI native space, but Integration Cloud has been moved towards the Apps space. in many respects this reflects a low code vs code native model.
Earlier this year (2020) Oracle launched a brand new ODI product, to use its full name Oracle Cloud Infrastructure Data Integration. This is an OCI native (i.e. Gen2 solution leveraging microservices technologies).
This new product appears to be a very much ground up build as it exploits Apache Spark and Function as a Service (FaaS) as foundational elements. As a ground up build, it doesn’t inherit all the adapters the original ODI can offer. This does mean as a solution today it is very focused on some specific needs around supporting the data movement between the various Oracle Cloud storage and Database as a Service solutions rather than general ingestion and extraction processes.
Products are evolving, but the direction of travel appears to be resolving. But we are still in that period where there are capability gaps between the Gen2 native solution and the traditional ODI via Marketplace solution. As a result the question becomes less which product, but when and if I have to invest in using ODI Marketplace how to migrate when the native product catches up.
