Setting up Etcd cluster with DNS discovery

Setting up an etcd cluster with DNS discovery may be challenging. There are several building blocks:

  • Etcd – a distributed key value store
  • Amazon EC2 – cloud computing provider
  • Cloudflare – DNS provider
  • Chef – for configuring individual nodes

Each of them has their pitfalls, we will guide you through whole process.

DNS discovery

Any clustered system needs a way to maintain a list of nodes in a cluster. Usually you need to specify all cluster members when starting a node. This is the way zookeeper and consul works. Effectively you have redundancy in configuration – the list of nodes is stored on every node. The list must be consistent and it’s difficult to maintain it especially if the cluster …

We are big fans of automation which is also one of the reasons why we started TwinDB. We want to remove the pain around manual redundant jobs and automate them so that you can focus on what is important for your business.

Why Chef?

Awesome Chef

Chef is a great example of how automation can be successfully applied to infrastructure such that your infrastructure becomes easily deployable, manageable, testable and well documented. Whenever, I talk about the benefits of using Chef, I greatly highlight how writing Chef cookbooks essentially documents your infrastructure. Isn’t it great to have a well documented infrastructure, that anyone can reference to? How many times have I not heard someone tell me how they have no idea how a particular service was deployed, or what was deployed on a particular machine? Many many times, …

New Webinar: A DevOps Guide to Database Infrastructure Automation for eCommerce

For an online shop, the website is the cash register. It has to be open for business 24 hours a day.

As the ops person on duty, when you get a call at 3am after your website went down, your priority number one is to restore the service asap. But why can we not have our application stack automatically recover, and not have the pager wake us at all? Why do we still stick to tedious manual processes, which take up time and resources, and hinder future growth?

Infrastructure automation isn’t easy, but it’s not rocket science either, says Riaan Nolan. Riaan has been in operations for the past decade, and has built over a dozen eCommerce properties. Automation is a worthwhile investment for retailers serious about eCommerce, but deciding on which tools to invest in can be a confusing and overwhelming process.

Join us for this webinar to understand the key pain points that online retailers experience which indicate it’s time …

The Tools To Use

Over the past couple of years, several tools have come up to solve some of the long standing problems for developers, DBAs and operations teams. This list is no where near exhaustive and your mileage may vary.

These tools should let you get up and coding, saving your code to a central place.

I run (Mac/Windows), I need a Linux server to learn some of this cool stuff, right?

Not exactly. VirtualBox is a virtualization project for multiple platforms (Mac, Win, Linux, Solaris) that allows you to run a guest OS right from your laptop or desktop. There are repositories of images (alternative here) that you can use to get yourself going quickly, or you can provision your own.

I set up (cool open source package here) and now my team …
