Summary description of the AWS technical and contractual setup:
The eServices platform is hosted on Amazon Web Services (AWS) cloud servers. The servers are in
Stockholm, Sweden (EU-North-1 region), each with redundant power, networking, and connectivity, housed
in separate facilities. This ensures that if one data center is down, the service can be picked up by another
one, thus reducing the risk of service interruptions.
The eServices platform uses a microservices architecture. Microservices means the system is divided into
smaller, independent services that work together. AWS provides auto-scaling, load balancing, and multi-
availability-zones (AZ) deployments. This means the eServices platform’s workload can be automatically
spread across multiple servers and availability zones. Therefore, if one server or zone goes down, the
overall system still stays operational since the work is distributed.
Data is neither transferred outside the EU, nor is it shared with third parties. Only external users with
authorized rights can see the personal data contained in e-Register and ESIS. Internally, only users with
defined access rights can see personal information.
The migration of the above applications to the eServices Platform and thus to AWS cloud is planned to start
in December 2024, with the migration of the public User Interface (front-end) of the two applications, after
which the back end will follow.
AWS is being utilized by Nasdaq for Infrastructure-as-a-Service (IaaS) platform. Nasdaq has an enterprise
agreement with AWS that establishes a master service agreement covering all Nasdaq group companies
including NCSD. This ensures consistent terms and conditions when using AWS cloud infrastructure
services.
Nasdaq Stockholm has entered into an agreement with Amazon Web Services, Inc., (“AWS, Inc.”) and an
affiliate of AWS, Inc., Amazon Web Services EMEA SARL L (together with AWS, Inc., “AWS”) related to
generally available services made available by AWS through the AWS Management Console (hereinafter
– AWS Cloud).
AWS Customer Agreement is available at: http://aws.amazon.com/agreement (as updated from time to
time). Additionally, Nasdaq has signed addendums for, among others, data processing (data processing
requirements and restrictions) and financial services (outsourcing related requirements).
Nasdaq Stockholm has outsourced the AWS Cloud through a sub-outsourcing arrangement to Nasdaq
CSD SE and other affiliates on December 21, 2022.
The outsourcing chain used by Nasdaq CSD was assessed according to the outsourcing policy in place
and brought to the Management Board for approval on November 19th, 2023. The assessment concluded
that the outsourcing was not critical considering that only the submission of corporate actions (CA) was in
scope. The results of the assessment were communicated to the Estonian Ministry of Finance.
