Failover Conf – A sense of normalcy

In early March when the Coronavirus had started to impact us in many different ways, one of which being that tech conferences all over the world was being cancelled or postponed, our good friends over at Gremlin started planning for a virtual conference with the goal of helping everyone maintain a sense of normalcy.

    Migration of Branäsgruppen AB to AWS


    The Challenge

    Ski resorts are inherently seasonal, since we can only ski when there is snow!  During these times, the vast majority of the group’s trade is made.

    Branäsgruppen’s outgoing IT infrastructure was based on VMWare’s ESXi solution, supported by technicians skilled in managing on-premises solutions, from Opsio.  The ski window is usually between December and April each year, meaning 5 months of extremely high traffic to the Branäsgruppen’s websites and online applications.
    They use their IT estate to host their websites and information, including webcam images from the slopes.  These resources are heavily relied upon, and so need to be reliable.
    Scaling of the web front-ends, middleware, and most challenging of all, back-end databases needed to be done manually, and in response to demand.  This meant that before a scaling event, performance of the group’s IT estate would drop below the high standards set by the business.
    Connected to the issue of scale, was a problem of deploying new software to the now fragmented virtual server estate.  Technicians would need to bring the whole environment down to be able to update the software deployed across the VMWare estate.
    A new solution to the problem of flexibility needed to be found, which is where Opsio helped.

    The Solution

    Opsio understands that serverless technology is a game changer, and so deployed AWS Aurora serverless as the back-end database solution. This enables the back-office processes to scale across availability zones, and across as much compute and storage resource as required.  Not only does this solve the scalability issue being felt so keenly by the client, but improves the availability of service and durability of their business-critical data, which was another key requirement.


    The Results

    Branäsgruppen measure the success of the AWS deployment project by the customer engagement they receive from their online presence, andsatisfaction feedback they receive from their customers.
    Uptime of the web applications has improved, and so has latency for those clients who are actively engaging with the applications.  Since studies show that a more responsive web application experience manifests in higher conversion rates, this was of key importance to Branäsgruppen, and we are pleased to be able to report a 40% improvement in average page responsiveness.

    About The Company

    Branäsgruppen one of the largest ski resort groups in Sweden, and has a prestigious brand to uphold.  Since taking over the resort in 2004, the group has strengthened the business, and increased visitor numbers to 15,000 riders per day at peak times.
    Their ski packages are renowned for their quality and reliability, meaning their online presence has to match their corporate image.

    Migration Of ETNetwork To AWS


    The challenge

    ETNetwork infrastructure was hosted from one datacenter, with inadequate redundancy and resilience when weighted against their growing customer base and with that the increasing demands on performance, availability and security.  The nature of their business is such that they need to store millions of small files, and this was causing issues for their storage tier.

    The business also demanded the highest standards for security, great performance, high availability, scalability and speed to market, and these goals were becoming difficult to achieve with in-house resources.  It was also clear that a partner was needed to help with this digital transformation and to keep that continuous transformation. ETNetwork reached out to Opsio because of their status as an AWS Advanced Consulting Partner and their unique managed services offering.

    The goal had to be to secure and grow the ETNetwork business, and to use the AWS global network and their nordic presence with datacenters in Sweden to achieve this.


    The solution


    As per Opsio’s strong culture of DevOps, everything we created for ETNetwork was deployed using CloudFormation.  We achieved a flexible, redundant and complete infrastructure by developing separate CloudFormation templates for the core infrastructure, another for the continuous integration/continuous deployment pipeline for Code Commit and Code Build and lastly a template for the tasks running in AWS’s managed Container service, ECS.


    The Results 

    Managed Support

    Now that ETNetwork’s Kwick solution has been migrated into the AWS cloud, they are able to take advantage of Opsio’s talented and experienced resources as part of the managed service. ETNetwork now have access to AWS certified technicians to monitor and manage their platform 24/7, with fast response times whenever intervention is required, and as per the agreed Service Level Agreement (SLA).

    ETNetwork also have access to CloudOps and DevOps engineers who ensure continued use of automation and continuous optimization of the platform. And all of this is managed by a dedicated Service Delivery Manager, which works closely with the client to ensure their business flourishes as a result of a well delivered managed cloud service.

    Cost Effectiveness

    As existing environment was running in an hosted VMware environment without autoscaling possibilites Opsio where able to decrease the monthly cost by 30% by following AWS Well Architected Framework.


    ABOUT The Company

    ETNetwork are the company behind the revolutionary new digital receipt application, Kwick. Based in Sweden, and serving the whole Nordic area, the company has experienced huge growth, with many more merchant and corporate partners joining the technical revolution created around the Kwick application.

    Their technologies reach from capturing digital receipts from smart credit and debit cards, all the way to helping amusement parks cut their paper consumption by 80% and increasing user’s convenience by deploying paperless technology for the park guests.

    In Sweden alone, 60,000 trees are cut down every year to fulfil the demand for paper receipts. ETNetwork saw the opportunity presented, whereby they could help cut the environmental impact of this, and to increase the efficiency of businesses at the same time. Since the Swedish tax agency’s decision to accept digital receipts as of December 2013, the time was right for ETNetwork to facilitate the positive change they wanted to see.

    Their mission is to provide high value services around transactions and have a positive effect on the environment.



    Opsio were the obvious choice for ETNetwork to use as their cloud architecture partner because of our rich culture of DevOps and reputation for working with high-profile clients who depend on Opsio-built solutions for their line of business applications every day.

    Being one of the more established cloud solutions organizations, Opsio understands what is important to businesses, and has the ability to shape technology solutions around business problems – not the other way around. The Opsio team are able to work with client organizations at all levels to help project manage, resource, deploy and test solutions. ETNetwork needed a partner to work with who could deliver a full solution.
