By Werner Vogels on 05 March 2012 02:01 PM. AWS today announced a substantial price drop from March 1, 2012 for many of the Amazon EC2, Amazon RDS, and Amazon ElastiCache instances types around the world. We continuously apply all our innovative skills to the design of datacenters, servers, storage, network, etc.

The best part is that we are also significantly expanding the free tier many of you already enjoy by increasing the storage to 25 GB and throughput to 200 million requests per month. We designed DynamoDB to operate with at least 99.999% availability. In 2012, we launched Amazon DynamoDB, the successor to Amazon Dynamo.

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.

DynamoDB has come a long way in the 5 years since we announced its availability in January 2012. DynamoDB was the first service at AWS to use SSD storage. I've had a chance to interact with many of these customers on the design of their apps. When you write an application, you might not need or design for caching on day one.

When we released Always On Availability Groups in SQL Server 2012 as a new and powerful way to achieve high availability, hardware environments included NUMA machines with low-end multi-core processors and SATA and SAN drives for storage (some SSDs). Our design needed to scale and be adaptable to the modern hardware on the market.

The benefits to apps that adopt WebView-based IABs are numerous: WebViews are system components designed for use within other apps. Here, native apps are doing work related to their core function; storage and tracking of user data are squarely within the four corners of the app's natural responsibilities.

Internally DBCC CHECK* uses a page scanning coordinator design (MultiObjectScanner.) SQL Server 2016 changes the internal design to (CheckScanner), applying no lock semantics and a design similar to those used with In-Memory Optimized (Hekaton) objects, allowing DBCC operations to scale far better than previous releases.

To provide some coherence to the music, I decided to use Taylor Swift songs since her discography covers the time span of most papers that I typically read: Her main albums were released in 2006, 2008, 2010, 2012, 2014, 2017, 2019, 2020, and 2022. This choice also inspired me to call my project Swift Papers.
