In 2018, that found the compute power used by the largest AI training runs has doubled every 3.5 months since 2012. From autonomous vehicles to DNA analysis, there's little doubt the demand for machine learning and AI is driving the supply of increased computing power today. OpenAI released a study This can leave many organizations priced out of the AI race. You're at a distinct disadvantage if your competitors can afford the computing power to train models and apply them more quickly than you - so why bother? But AWS announced in the summer of 2019 that , which can help make effective machine learning more obtainable for more organizations. SageMaker can now manage Spot instances without needing additional tooling are Amazon's unused cloud computing capacity AWS sells at a steep discount. They are the exact same as On-Demand EC2 instances in terms of capabilities and infrastructure, except that AWS can reclaim the Spot instance and sell it back to On-Demand customers when necessary. How much of a discount and how frequently the Spot instance is interrupted can depend on the instance type and Availability Zone. Spot instances To get a better estimate on how much more computing power you could harness at lower prices, check out the . For example, a Spot p3.16xlarge in the US East, Ohio AZ costs 70% less than On-Demand and is interrupted by Amazon less than 5% of the time. In the EU, Frankfurt AZ, a Spot g3s.xlarge also costs 70% less than On-Demand, but is interrupted much more frequently at >20%. While in the newer Middle East, Bahrain AZ, no P instances are even offered and g4s are the only available accelerated computing instance offered on Spot. Spot Instance Advisor here Amazon regularly updates the Spot Instance Advisor based upon market trends, but Spot no longer relies on a complicated, frequently-changing bidding process. You simply tell AWS the maximum price you're willing to pay for the Spot instances and if they're available - at a price less than the maximum - you get them at the current Spot price. This makes the cost and interruption trends more stable and easier to predict. You can read more about this . change in Spot's pricing model on the AWS Blog here So depending on the requirements of a workload and how well it can manage interruption, Spot instances may not always be right fit - but it's almost always a good fit for SageMaker. As the ,  it's a "no-brainer" to use Spot for transient workloads like machine learning. , now with support for Spot, it's making it easier to implement and more affordable. AWS Podcast noted in their discussion on Spot instances SageMaker already made managing distributed training relatively easy Before, engineers would have to do the extra work of checkpointing and restoring interrupted workloads, as . Now, with a simple adjustment in the settings wizards or SDK, SageMaker will copy checkpoint data over to S3 when a Spot instance is interrupted - and restore the data and resume when the excess computing becomes available again. described on Hacker Noon by Vadim Fedorov here Recently the . Not only is the inherent batch workloads of machine learning a challenge for traditional on-premise infrastructure, but Cinnamon AI had separate development environments for their products that they were able to consolidate all onto AWS. AWS Blog shared about how Cinnamon AI and their migration of their machine learning workloads from on-premise to SageMaker After optimizing their training to run on and On-Demand P2 and P3s, Cinnamon AI then able to take advantage of its integrated Managed Spot Training feature. Today, almost all their model trainings run on Spot, which reduced their compute costs by 70%. They were able to invest those savings into running 40% more daily jobs, while still lowering their overall machine learning costs. SageMaker So don't assume just because you don't have the big bucks, doesn't mean you can't get the big insights of machine learning. With the discounts of Spot instances and the new ease of their integration with SageMaker, more and more savvy engineers can take advantage of AI. I hope this has been a helpful primer on one way your organization can effectively join the AI race - better than your competitors.
