Interview With Ofer Bengal, CEO Of Garantia Data, On Redis And The NoSQL Landscape

Cloud Computing Today recently had the privilege to interview Garantia Data CEO Ofer Bengal about the positioning of Redis within the larger landscape of NoSQL databases. Redis is an an open source, in-memory, key value data store. In his responses to the questions below, Bengal remarks on the ability of Redis to “serve a very high volume of write and read requests…at sub millisecond latency,” its “single threaded event-driven architecture,” and protocols that, in collaboration with its other features, render it 5-10 times faster than other in-memory databases. Bengal also elaborates on the richness of data structures within the Redis platform that empower developers to write more elegant and streamlined code.

Garantia Data’s core offering consists of the Redis Cloud and Memcached Cloud on well known cloud platforms such as Amazon Web Services and Windows Azure. Its Redis Cloud platform provides a fully managed service for Redis deployments that includes handling of scalabilty and failover considerations. Garantia Data recently acquired MyRedis, a production-grade deployment of Redis that runs on Heroku and AppHarbor.

1. Cloud Computing Today: Why, in your view, will Redis become the preferred database technology platform?

Ofer Bengal: NoSQL databases like Redis are becoming increasingly popular. According to a 451 Research report, Redis adoption is projected to increase from 11.3 percent today to 15.9 percent in 2015. Redis in particular will become a preferred database technology because it is faster than any other database and it has rich data structures – which are very similar to those of today’s high level programming languages. Leading companies like Twitter and Pinterest use Redis, which shows it is highly useful for companies with rapidly growing datasets.

2. Cloud Computing Today: What differentiates the performance of Redis from other datastores?

Ofer Bengal: Redis is an in-memory database designed from the ground up to serve a very high volume of write and read requests (over 100K ops/sec on a typical cloud instance) at sub millisecond latency. This, in most cases, means two orders of magnitude faster than other disk-based databases. Versus other in-memory databases, Redis is based on a single threaded event-driven architecture which frees it from lock mechanisms. In addition, its protocol is simple and fast to process – making Redis 5x-10x times faster than any other in-memory database available today.

3. Cloud Computing Today: What makes developing apps with Redis a much simpler task than with other database platforms?

Ofer Bengal: Redis has a rich set of data structures which are very similar to those of today’s high level programming languages. Users are also able to do more with Redis as an in-memory database because it is less complicated to manipulate than the same data structure on disk. This means developers do far less damage to the concepts of their programs when using Redis, resulting in faster development, improved code quality and more attractive code.
