What is an AWS region?

The AWS Global infrastructure is built around Regions and Availability Zones (AZs). AWS Regions provide multiple, physically separated and isolated AZs which are connected with low latency, high throughput, and highly redundant networking. These AZs offer AWS customers an easier and more effective way to design and operate applications and databases, making them more highly available, fault tolerant, and scalable than traditional single datacenter infrastructures or multi-datacenter infrastructures.

AWS Regions and AZs.

Why having multiple AZs in a single Region is important?

While each AZ is fully independent from one another, with redundant power, networking and connectivity, and housed in separate facilities, AZs are connected through low-latency links allowing for latency of approximately 1-to-2ms between each AZ. Such a low latency allows for synchronous replications between the different AZs. This is a foundational principle for high-availability and fault-tolerance on AWS. Indeed, if one of the AZ in a particular region would experience intermittent issues, the other AZs, independent, would be able to continue operating.

Why an AWS region in the Nordics?

It’s no surprise that AWS would want to add the Nordics into our collection of what is now 20 geographic regions around the world. And no, it’s not because of the ridiculously low temperatures we hit in the winter, but because it’s home to a thriving startup community churning out innovative technologies and companies.

Why does it matter for startups?

Having an AWS region in Sweden will further accelerate the development of new startups as they will now have access to all the cutting edge technologies available in an AWS Region; think machine learning, compute, storage, Internet-of-Things and all the data processing services to name a few, with very low latency. This will be a massive boost for those industries the Nordics has a particularly strong foothold in: Fintech, Gaming, Media, Automotive and of course Sustainability.

Longer ski run …

But don’t just take out my word for it. Having the AWS region in Sweden helped the Vilsta ski slope in Eskilstuna, Sweden add 10 more meters — just in time for the winter season! Yes, you read that right. Thanks to the shaft masses from the construction of the datacenters in Eskilstuna, the Tunafors Ski Club raised their ski slope and improved the ski run by 30 meters with four to five more turns at the Vilsta ski resort — now that Rocks-as-a-Service my friends!
