Brief notes from AWS Community Day Nordics

On last Wednesday the tradition began at Clarion Helsinki. Over 300 AWS enthusiastics witnessed the arrival of the AWS Community Days to Nordics. The structure of the one day event was following to the typical seminar day, with keynotes and multitrack sessions. Slides are expected to be available afterwards. Tracks were titled with ‘Main’, ‘Serverless’, and ‘Data + ML’ and for the two latter ones the content were pretty self-explanatory. I participated in Serverless track but unfortunately, I was not able stay for the whole day due to the other commitments. The serverless approach was also present in the first keynote where Martin Buberl from Trustpilot discussed the journey they have had towards serverless architecture. The number of EC2s has been decreased as tasks have been processed by Lambdas instead. And as a EC2 is typically replaced by more than single Lambda, it is expected that the number of Lambdas is growing faster than the number of EC2 is shrinking.

The first session at Serverless track was hosted by Paul Lyons from Nordcloud and it focussed on Serverless framework. The demo was about serverless backend but the content was not the most interesting element. The framework was somewhat familiar for me in advance but the discussions strengthened my understanding that for the serious serverless approach the Serverless framework is a great tool. Serverless Framework can be used with various plugins and the related community is active. For example there is plugin for a rather new service called AppSync (my personal favorite service currently). Paul mentioned during his show that S3 event trigger for Lambda is not working well at the moment with Serverless and one have to activate that in the console. Using console is something that is not preferred when using Serverless…

Fellows from Zalando, Uri Savelchev & Ruben Diaz, discussed about Kubernetes. They have built custom deployment tool as they had found all available tools cumbersome to some extent, at least out-of-the-box. Zalando has independent teams and these teams operate in various sites in Europe. As a result they have numerous AWS accounts. Zalando seems to utilize AWS a lot.

It was a great day and I got lots of new ideas. Hopefully the next Community day is not too far away.
