From the post:
Aerospike – the first flash-optimized open source database and the world’s fastest in-memory NoSQL database – will be at Amazon Web Services (AWS) re:Invent 2014 conference in Las Vegas, Nev.
An ultra low latency Key-Value Store, Aerospike can operate in pure RAM backed by Amazon Elastic Block Store (EBS) for persistence as well as in a hybrid mode using RAM and SSDs. Aerospike engineers have documented the performance of different AWS EC2 instances and described the best techniques to achieve 1 Million transactions per second on one instance with sub-millisecond latency.
The Aerospike AMI in the Amazon Marketplace comes with cloud formation scripts for simple, single click deployments. The open source Aerospike Community Edition is free and the Aerospike Enterprise Edition with certified binaries and Cross Data Center Replication (XDR) is also free for startups in the startup special program. Aerospike is priced simply based on the volume of unique data managed, with no charge for replicated data, for Transactions Per Second (TPS) or number of servers in a cluster.
Aerospike is popularly used as a session store, cookie store, user profile store, id-mapping store, for fraud detection, dynamic pricing, real-time product recommendations and personalization of cross channel user experiences on websites, mobile apps, e-commerce portals, travel portals, financial services portals and real-time bidding platforms. To ensure 24x7x365 operations; data in Aerospike is replicated synchronously with immediate consistency within a cluster and asynchronously across clusters in different availability zones using Aerospike Cross Data Center Replication (XDR).
This is not a plug for or against Aerospike. I am mostly posting this as a reminder to me as much as you that cloud data prices can be remarkably sane. Even $1.68 per hour could add up over a week but if you develop locally and test in the cloud, you should be able to meet your budget targets.
For any paying client, you can pass the cloud hosting fees (with an upfront deposit and one month in advance) to them.
Other examples of reasonable cloud pricing?
