Super-Resilient Images – Served From Around The World

Project Snow Cloud: Making dotMailer's Images More Resilient Than Ever

When I first came to work for dotMailer, we worked in a compact and anonymous office. But the company has grown unstoppably, and as we grew, we grew our digs too. Today I write this blog whilst looking out from our modern 20th floor office, over a cloudy London horizon. Pretty apt, as we’re about to move some of dotMailer’s infrastructure into the cloud, too.

What is the ‘cloud’?

Simply put, it’s a way to use very large scale computing resources that are distributed around the world. You’ve entrusted us with many millions of your images, and we need to make sure they’re always available – and always accessible – wherever in the world you are. We’ve been looking after these in our own data centres up until now, but the cloud offers us so much more.

And we’ll hold our hands up – we’ve recently had problems with image availability. This caused a number of you some frustration, and frankly, that wasn’t good enough.

This has led us to partner with Amazon, whose 99.99% availability and 99.999999999% durability convinced us it was time to move. This erstwhile online bookshop has grown into a behemoth of a computing services platform, and many thousands of companies now entrust Amazon with online storage duties. With huge data centres in dozens of countries, they’re ideally placed to handle our increasingly international workload.

As a recipient of an email sent with dotMailer, this change means you’ll see images appear faster than ever. If you open a dotMailer campaign, its images will no longer load from our London data centre, but will instead come from the Amazon data centre nearest to you – whether that’s Seattle, Seoul, Stockholm, or Sydney.

We’ll be rolling this change out gradually to all account holders over the next few weeks, so stand by for even faster speeds.
