Editor's Notes
- #3 Put simply, there are two big questions that I think define and drive in-memory computing: How can we process data s fast as possible by leveraging in-memory speed at it’s best? Secondly, what are the possibilities if we could?
- #4 Why do we care about speed? It matters in a lot of cases… In the Financial world, it matters in areas like High Frequency trading, which is estimated to account for 50-70% of trades in the past 5 years. HFT platforms transact a large number of orders at very fast speeds, and often use complex algorithms to analyze multiple markets and market conditions Typically, the traders with the fastest execution speeds are more profitable than traders with slower execution speeds.
- #5 Research by Enterprises and Analysts correlating performance, online experiences and revenue are well documented. I list a few here from some Analysts and Amazon, but there are other public studies from Google and Walmart demonstrating the same Well known study by Aberdeen Group discovered: A 1-second delay in page load time equals 11% fewer page views, a 16% decrease in customer satisfaction, and 7% loss in conversions translated to dollars, if your business earn just $100,000 a day, this equates to $2.5M in potential sales annually. – faster is better. Slow online experiences translate to lost opportunities and we as users and consumers can relate.
- #6 So, how fast is in-memory? Here’s the rough units that best measure data access times across different storage mediums. Click If we normalize to 1s, it is clear that the magnitude in speed is drastic between RAM and even fast SSD storage.
- #7 Some may already be nodding their heads… RAM isn’t new technology, and we’re aware that the price of RAM has dropped drastically over the decade. By 2010, the sharp decline in average cost has made RAM “generally affordable” for mainstream use; however, it is far from cheap especially when we consider the data volumes that we work with today.
- #8 However, prices continue to fall, and an average price of $4.37 in 2015 make RAM an option even at scale for greenfield projects that need the speed.
- #9 IOT is certainly not a space short of innovation and possibilities, and the ability to scale in-memory performance only makes possibilities more exciting. I came across an article where Audi is discussing their plans for their connected self-driving car, and their intentions to send data collected from various sensors on the car back to the cloud where they will leverage ML to process data to send back to the car so that it can learn and better adapt to complex situations. “…machine learning it will mean adverse weather conditions, such as snow, which can affect sensors will be less of a problem as cars will have a thorough understanding of the piece of tarmac it is traversing” Consider the future, the scale of every vehicle on the road, the amount of data collected that needs to be processed. In-memory computing solutions will be needed to process big data fast especially in the world of smart cars where information will drive important decisions in real-time.
- #10 Despite the significant increase in the amount of RAM you could put on a single server in the past couple of years, there are still limits, and the data volumes that we work with today continue to grow due to the type of applications we build, and the type of data sources we analyze and data mine. For many organizations, the bulk of workloads are being moved to or are in the cloud, and the ability to scale on cloud infrastructure is critical. The ability to scale-out to fit large data-sets in RAM across servers is critical. If not, data volume, then compute to support large scale services in the cloud.
- #11 We previously discuss how cost has lowered dramatically, and while it is an option at scale, it can still be cost prohibitive for certain projects. Consider AWS’s X1 instance. Impressively provides nearly 2TB of RAM, but at a hefty price. At a scale of 100TBs, $1.74M just for infrastructure isn’t an option for certain projects. Question is, does the problem really require to have all your data in RAM?
- #12 While memory is magnitudes faster than other storage mediums, the difference in relative cost is also significant. With that said, in-memory solutions shouldn’t be designed around needing your Enterprise data-architecture or even application to run entirely in-memory. The value of the data and the problem you’re solving should dictate what is the right medium, and an in-memory solution should seamless integrate into a Enterprise Data Architecture that supports all storage mediums.
- #13 Generally, when we talk about memory we refer to what is readily available-- volatile memory; if you server goes down, then the data stored in that server’s RAM is lost unless it has also been put on durable storage like disk. Trading off data-loss for speed, in most use cases, isn’t acceptable. A good in-memory solution needs to provide fault tolerance, and it needs to synchronize with durable storage, and just as importantly, simply and reliably (which often isn’t the case for some solutions like external distributed caches).
- #14 As fast as RAM is, it doesn’t remedy bad design. More importantly, any in-memory computing technology shouldn’t introduce new bottlenecks into the architecture, or limit your data architecture to addressing the biggest performance bottlenecks in your system. For instance: Does your in-memory computing solution require you to move large volumes of data around? If so, is that creating bottlenecks in other ways? How does your solution bring data into RAM? Is there an efficient caching algorithm, and is relevant data selected and filtered efficiently? How is your data being processed in RAM? Is there an efficient algorithm? Is it introducing inefficiencies and new performance bottlenecks by shuffling data unnecessarily across a distributed system?
- #15 So know that we understand the challenges and core requirements around introducing in-memory technologies into your Enterprise Data Architecture, let’s understand how MongoDB fits into the big picture and what it can offer in this area.
- #19 Let’s hone in on the product catalog and customer session management parts of the system as the problem is most clear. Customer session management component is key to driving customer experience like personalization, and effective personalization needs to be based on full picture of the customer – realistically, in an Enterprise, customer touch points and information is siloed across many systems, and rarely is there one place in an Enterprise where an operational system can get everything it needs to know about the customer. Likewise, with the Product Catalog, information about products will be siloed. Perhaps some info is stored within the ecommerce platform, but likely has to be synchronized with external systems like PIMs, and Supplier systems. Additionally, a modern platform should also be able to keep availability up to date as part of the product search, so problems aren’t caused downstream around order fulfillment. Finally, the business analysts will also need to analyze the same data sources. Consolidating these systems isn’t realistic Integration is necessary, and ideally it shouldn’t involve heavy redundancy; for instance, across operational and BI environments. Federated data access of these systems isn’t an option on many fronts due to performance and scale. Sufficient integration of data into the DW via traditional ETL is a huge effort and likely too slow to make happen.
