Ten years ago, a database was needed to scale out for both reads and writes to meet the long-term needs of a growing business. The Amazon Dynamo database was developed and WERNER VOGELS, CTO of Amazon.com explains how its has grown from then.
It all started in 2004 when Amazon was running Oracle’s enterprise edition with clustering and replication. We had an advanced team of database administrators and access to top experts within Oracle. We were pushing the limits of what was a leading commercial database at the time and were unable to sustain the availability, scalability and performance needs that our growing Amazon business demanded.
Our straining database infrastructure on Oracle led us to evaluate if we could develop a purpose-built database that would support our business needs for the long term. We prioritized focusing on requirements that would support high-scale, mission-critical services like Amazon’s shopping cart, and questioned assumptions traditionally held by relational databases such as the requirement for strong consistency. Our goal was to build a database that would have the unbounded scalability, consistent performance and the high availability to support the needs of our rapidly growing business.
A deep dive on how we were using our existing databases revealed that they were frequently not used for their relational capabilities. About 70 percent of operations were of the key-value kind, where only a primary key was used and a single row would be returned. About 20 percent would return a set of rows, but still operate on only a single table.
With these requirements in mind, and a willingness to question the status quo, a small group of distributed systems experts came together and designed a horizontally scalable distributed database that would scale out for both reads and writes to meet the long-term needs of our business. This was the genesis of the Amazon Dynamo database.
The success of our early results with the Dynamo database encouraged us to write Amazon’s Dynamo whitepaper and share it at the 2007 ACM Symposium on Operating Systems Principles (SOSP conference), so that others in the industry could benefit. The Dynamo paper was well-received and served as a catalyst to create the category of distributed database technologies commonly known today as “NoSQL.”
Of course, no technology change happens in isolation, and at the same time NoSQL was evolving, so was cloud computing. As we began growing the AWS business, we realized that external customers might find our Dynamo database just as useful as we found it within Amazon.com. So, we set out to build a fully hosted AWS database service based upon the original Dynamo design.
The requirements for a fully hosted cloud database service needed to be at an even higher bar than what we had set for our Amazon internal system. The cloud-hosted version would need to be:
- Scalable – The service would need to support hundreds of thousands, or even millions of AWS customers, each supporting their own internet-scale applications.
- Secure – The service would have to store critical data for external AWS customers which would require an even higher bar for access control and security.
- Durable and Highly-Available – The service would have to be extremely resilient to failure so that all AWS customers could trust it for their mission-critical workloads as well.
- Performant – The service would need to be able to maintain consistent performance in the face of diverse customer workloads.
- Manageable – The service would need to be easy to manage and operate. This was perhaps the most important requirement if we wanted a broad set of users to adopt the service.
With these goals in mind, In January, 2012 we launched Amazon DynamoDB, our cloud-based NoSQL database service designed from the ground up to support extreme scale, with the security, availability, performance and manageability needed to run mission-critical workloads.
Today, DynamoDB powers the next wave of high-performance, internet-scale applications that would overburden traditional relational databases. Many of the world’s largest internet-scale businesses such as Lyft, Tinder and Redfin as well as enterprises such as Comcast, Under Armour, BMW, Nordstrom and Toyota depend on DynamoDB’s scale and performance to support their mission-critical workloads.
DynamoDB is used by Lyft to store GPS locations for all their rides, Tinder to store millions of user profiles and make billions of matches, Redfin to scale to millions of users and manage data for hundreds of millions of properties, Comcast to power their XFINITY X1 video service running on more than 20 million devices, BMW to run its car-as-a-sensor service that can scale up and down by two orders of magnitude within 24 hours, Nordstrom for their recommendations engine reducing processing time from 20 minutes to a few seconds, Under Armour to support its connected fitness community of 200 million users, Toyota Racing to make real time decisions on pit-stops, tire changes, and race strategy, and another 100,000+ AWS customers for a wide variety of high-scale, high-performance use cases.
With all the real-world customer use, DynamoDB has proven itself on those original design dimensions:
- Scalable – DynamoDB supports customers with single tables that serve millions of requests per second, store hundreds of terabytes, or contain over 1 trillion items of data. In support of Amazon Prime Day 2017, the biggest day in Amazon retail history, DynamoDB served over 12.9 million requests per second. DynamoDB operates in all AWS regions (16 geographic regions now with announced plans for six more Regions in Bahrain, China, France, Hong Kong, Sweden), so you can have a scalable database in the geographic region you need.
- Secure – DynamoDB provides fine-grained access control at the table, item, and attribute level, integrated with AWS Identity and Access Management. VPC Endpoints give you the ability to control whether network traffic between your application and DynamoDB traverses the public Internet or stays within your virtual private cloud. Integration with AWS CloudWatch, AWS CloudTrail, and AWS Config enables support for monitoring, audit, and configuration management. SOC, PCI, ISO, FedRAMP, HIPAA BAA, and DoD Impact Level 4 certifications allows customers to meet a wide range of compliance standards.
- Durable and Highly-Available – DynamoDB maintains data durability and 99.99 percent availability in the event of a server, a rack of servers, or an Availability Zone failure. DynamoDB automatically re-distributes your data to healthy servers to ensure there are always multiple replicas of your data without you needing to intervene.
- Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases. In addition, DynamoDB Accelerator (DAX) a fully managed, highly available, in-memory cache further speeds up DynamoDB response times from milliseconds to microseconds and can continue to do so at millions of requests per second.
- Manageable – DynamoDB eliminates the need for manual capacity planning, provisioning, monitoring of servers, software upgrades, applying security patches, scaling infrastructure, monitoring, performance tuning, replication across distributed datacenters for high availability, and replication across new nodes for data durability. All of this is done for you automatically and with zero downtime so that you can focus on your customers, your applications, and your business.
- Adaptive Capacity –DynamoDB intelligently adapts to your table’s unique storage needs, by scaling your table storage up by horizontally partitioning them across many servers, or down with Time To Live (TTL) that deletes items that you marked to expire. DynamoDB provides Auto Scaling, which automatically adapts your table throughput up or down in response to actual traffic to your tables and indexes. Auto Scaling is on by default for all new tables and indexes.
Ten years ago, we never would have imagined the lasting impact our efforts on Dynamo would have. What started out as an exercise in solving our own needs in a customer obsessed way, turned into a catalyst for a broader industry movement towards non-relational databases, and ultimately, an enabler for a new class of internet-scale applications.
As we say at AWS, It is still Day One for DynamoDB. We believe we are in the midst of a transformative period for databases, and the adoption of purpose-built databases like DynamoDB is only getting started. We expect that the next ten years will see even more innovation in databases than the last ten. I know the team is working on some exciting new things for DynamoDB – I can’t wait to share them with you over the upcoming months.
Welcome to world of 2099
The world of 2099 will be unrecognisable from the world of today, but it can be predicted, says one visionary. ARTHUR GOLDSTUCK met him in Singapore.
Futuristic structures tower over the landscape. Giant, alien-looking trees light up with dazzling colours amid the hundreds of plant species that grow up their trunks. Cosmetic stores sell their wares via public touch-screens, with products delivered instantly in drawers below the screens.
This is not a vision of the future. It is a sample of Singapore today. But it is also an inkling of the world we may all experience in the future.
Singapore was the venue, last week, of the World Cities Summit, where engineers, politicians, investors and visionaries rubbed shoulders as they talked about the strategies and policies that would enhance urban living in the future.
As part of the Summit, global payment technologies leader Mastercard hosted a small media briefing by one of Singapore’s leading thinkers about the future, Dr Damian Tan, managing director of Vickers Venture Partners. The company’s slogan “We invest in the extraordinary,” offers a small clue to Tan’s perspective.
“We look as far forward as 2099 because, as a venture capital firm, we invest in the long term,” he tells a group of journalists from Africa and the Middle East. “Companies explode in growth because there is value in the future. If there is no growth, they won’t explode.”
The big question that the Smart Cities Summit and Mastercard are trying to help answer is, what will cities look like in the year 2099? Tan can’t give an exact answer, but he offers a framework that helps one approach the question.
“If you want to look at 81 years into the future, and understand the change that will come, you need to double that amount and look into the past. That takes us to 1856. The difference between then and now is the difference you can expect between now and 2099.”

Street art goes electric
Kaspersky Lab and British street artist D*Face have unveiled the first-ever “art helmet” design at the Formula E finale for electric cars in New York.
The ‘Save The World’ helmets will be raced by DS Virgin Racing’s drivers, Sam Bird and Alex Lynn, as they traverse the New York street circuit during the final races of the Formula E season.
The announcement signals the first art helmet by a Formula E team, continuing the heritage of art in motorsport and the cybersecurity brand’s commitment to contemporary art, creativity and innovation. D*Face took inspiration from Kaspersky Lab’s tagline, “A Company To Save The World”, and hopes that his colourful work will inspire people to take positive action.
D*Face will announce his first-ever art car design with a custom-made livery for the DS Virgin Racing Team. Its design will be released at the “Art Goes Green” event after Saturday’s race. The helmets and art car are the latest installations in the “Save the World” collection, following a major permanent public mural that was installed in Brooklyn, New York, in May.
D*Face, whose real name is Dean Stockton, said: “It is exciting to work with Kaspersky Lab on this project and create art with a real message of hope for a better future. After all, this is our world and we need to look after it. It will take every one of us to make a real lasting, impactful change. I love the mentality of the DS Virgin Racing Team and that of Formula E by showcasing sport in a way that doesn’t harm the environment, but is still just as exhilarating and fun.
“It is time for us all to stand together and make a change… be that stopping data steals, climate change, plastic waste or using damaging fuels. I want everyone to make a pledge to do one thing that will help make a change.”
As a sponsor of DS Virgin Racing Team, Kaspersky Lab is responsible for protecting the team’s devices against cyber threats. The company sees the technical environment in the global sport of Formula E as the next frontier in furthering its research and development of new technologies to keep vehicles secure in the digital world.
Sylvain Filippi, Managing Director at DS Virgin Racing, said: “The whole team fully supports this great initiative and our thanks got to Kaspersky and D*Face for their collaboration. It’s an honour to have such an innovative artist bring his talents to bear in our team ahead of the season-finale; the car, drivers’ crash helmets and mural all look amazing.”
Aldo Fucelli Pessot del Bo, Head of Global Partnerships and Sponsorships at Kaspersky Lab added: “There is a need for innovation on a global scale, both in contemporary art and in the fast-growing sport of Formula E. Now, for the first time ever, Kaspersky Lab is proudly bringing together the two sectors in an effort to Save the World and unleash creativity, encourage freedom of expression and further innovation.”
