My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Designed with High Availability in mind. We designed the framework to minimize database impact. Passive instances across regions are also possible, though it is recommended to operate in the same region as the database host in order to keep the change capture latencies low. Dumps can be taken any time, via a provided API.

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 cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. If those specs sound eerily familiar, it's perhaps because they're identical to 2016's $200USD Moto G4 , all the way down to the 2011-vintage 28nm SoC process node used to fab the chip's anemic, 2012-vintage A53 cores.

So when we launched in January 2012, we provided simple query functionality that used hash primary keys or composite primary keys (hash + range). When designing a new application that will operate in the AWS cloud, first take a look at DynamoDB when selecting a database. Since then, we have been working on adding flexible querying.

SEPTEMBER 26, 2016

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. CCT's core design is sound and has enormous potential if made mandatory in place of WebView IABs by the Android and Play teams. There's reason to worry that this is unlikely.
