AWS launches new time series database

AWS announced a new time series database today at AWS re:Invent in Las Vegas. The new product called DynamoDB On-Demand is a fully managed database designed to track items over time, which can be particularly useful for Internet of Things scenarios.

“With time series data each data point consists of a timestamp and one or more attributes and it really measures how things change over time and helps drive real time decisions,” AWS CEO Andy Jassy explained.

He sees a problem though with existing open source and commercial solutions, which says don’t scale well and hard to manage. This is of course a problem that a cloud service like AWS often helps solve.

Not surprising as customers were looking for a good time series database solution, AWS decided to create one themselves. “Today we are introducing Amazon DynamoDB on-demand, a flexible new billing option for DynamoDB capable of serving thousands of requests per second without capacity planning,” Danilo Poccia from AWS wrote in the blog post introducing the new service.

Jassy said that they built DynamoDB on-demand from the ground up with an architecture that organizes data by time intervals and enables time series specific data compression, which leads to less scanning and faster performance.

He claims it will be a thousand times faster at a tenth of cost, and of course it scales up and down as required and includes all of the analytics capabilities you need to understand all of the data you are tracking.

This new service is available across the world starting today.

The Cloud Native Computing Foundation adds etcd to its open source stable

The Cloud Native Computing Foundation (CNCF), the open source home of projects like Kubernetes and Vitess, today announced that its technical committee has voted to bring a new project on board. That project is etcd, the distributed key-value store that was first developed by CoreOS (now owned by Red Hat, which in turn will soon be owned by IBM). Red Hat has now contributed this project to the CNCF. Etcd, which is written in Go, is already a major component of many Kubernetes deployments, where it functions as a source of truth for coordinating clusters and managing the state of the system. Other open source projects that use etcd include Cloud Foundry and companies that use it in production include Alibaba, ING, Pinterest, Uber, The New York Times and Nordstrom. “Kubernetes and many other projects like Cloud Foundry depend on etcd for reliable data storage. We’re excited to have etcd join CNCF as an incubation project and look forward to cultivating its community by improving its technical documentation, governance and more,” said Chris Aniszczyk, COO of CNCF, in today’s announcement. “Etcd is a fantastic addition to our community of projects.” Today, etcd has well over 450 contributors and nine maintainers from eight different companies. The fact that it ended up at the CNCF is only logical, given that the foundation is also the host of Kubernetes. With this, the CNCF now plays host to 17 different projects that fall under its ‘incubated technologies’ umbrella. In addition to etcd, these include OpenTracing, Fluentd, Linkerd, gRPC, CoreDNS, containerd, rkt, CNI, Jaeger, Notary, TUF, Vitess, NATS Helm, Rook and Harbor. Kubernetes, Prometheus and Envoy have already graduated from this incubation stage. That’s a lot of projects for one foundation to manage, but the CNCF community is also extraordinarily large. This week alone, about 8,000 developers are converging on Seattle for KubeCon/CloudNativeCon, the organization’s biggest event yet, to talk all things containers. It surely helps that the CNCF has managed to bring competitors like AWS, Microsoft, Google, IBM and Oracle under a single roof to collaboratively work on building these new technologies. There is a risk of losing focus here, though, something that happened to the OpenStack project when it went through a similar growth and hype phase. It’ll be interesting to see how the CNCF will manage this as it brings on more projects (with Istio, the increasingly popular service mesh, being a likely candidate for coming over to the CNCF as well).
