Monsanto Increases Throughput by 100x with Oracle Coherence

In the video below Andrew Montgomery, Solutions Architect at Monsanto, how Monsanto uses Oracle WebLogic Server and Oracle Coherence to drive new products forward. Andrew give Coherence credit for increasing the throughput of one their application by 100x, being the cornerstone of horizontal scalability and a major piece of technology in new applications at Monsanto. Take a look: 

2013: The Year of The Data Grid and Beyond

The SDTimes just published an article entitled "In-memory data grids see 2013 as a big year" predicting that the in-memory data grid market will hit the $1 billion mark by 2016. While the article includes a number of perspectives on reasons for such growth and the future direction of the market, this singular point hits home for me and puts the past twelve years in perspective.

As employee #1 at Tangosol, I have seen the Coherence product come into being, watched it define a new market, innovate and lead that new market. This market continues to mature, customers continue to find new ways to apply the technology, influence and define new markets such as NoSQL and BigData and the ecosystem around Coherence continues to grow at a rapid pace. I personally look forward to 2013 and beyond as Coherence continues to lead the market growth towards the $1 billion mark.

I would be remiss if I did not point out one final quote in this article:

"[Oracle Coherence is the] in-memory data grid cited as the most popular by [Massimo] Pezzini [vice president and fellow at Gartner Research]"

Focus On The Community: Avoiding Multiple Simultaneous Database Calls When Using the Cache Aside Pattern

There are certain scenarios where you are not able to us Coherence's Read-Through capabilitiesIn such cases the Cache Aside pattern is most commonly used.

The "cache aside" pattern is perhaps the easiest way to introduce caching to an existing application. It usually requires the least disruption to code and can even be "injected" without code changes using AOP. Although it can seem trivial there are a few "gotchas". For example, when using the cache aside pattern, multiple simultaneous cache requests for the same piece of data across your environment will result in multiple database requests.

Here you can find a great article by Andrew Wilson from RBS explaining how this pattern has been implemented in a "real-world" solution and how to avoid these potential problems.
