Why Cloud Infrastructure Matters More Than You Think
Cloud infrastructure is not just a technical detail. It directly affects revenue. A one-second delay in page load can reduce conversions by 7%, according to research by Akamai. Downtime during a campaign launch or Black Friday event can cost you tens of thousands of SEK per hour. And a data breach caused by poor server configuration can damage trust permanently.
For ecommerce specifically, your infrastructure needs to handle unpredictable traffic patterns, serve assets quickly across geographies, and support the integrations that keep your business running—ERP, PIM, payment gateways, and shipping providers. The right cloud setup gives you the headroom to grow without rearchitecting everything every 18 months.
Most ecommerce teams we work with at Nordic Web Team fall into one of two camps: those on fully managed SaaS platforms like Shopify who want to understand what is happening under the hood, and those running self-hosted platforms like Shopware or Magento who need to make real infrastructure decisions. Both groups benefit from understanding the fundamentals. This guide covers the landscape so you can make informed choices regardless of where you start.
Hosting Models: SaaS, PaaS, and Self-Managed
The first decision is your hosting model. Each comes with trade-offs in control, cost, and operational complexity.
SaaS (Software as a Service)
Shopify is the clearest example. You do not manage servers. Shopify handles hosting, scaling, security patches, and uptime. You trade control for convenience. This works well for merchants who want to focus on products, marketing, and customer experience rather than infrastructure. The limitation is that you cannot tune server-level configurations or choose your own CDN provider.
PaaS (Platform as a Service)
Norce operates as a headless commerce platform hosted on Azure. You get managed APIs and do not run your own commerce backend servers. But you still need to host your frontend, which typically runs on Vercel, Netlify, or a cloud provider like AWS or Azure. This split model is increasingly common in composable commerce setups.
Self-Managed Cloud
Shopware and Magento / Hyvä can be deployed on AWS, Google Cloud, Azure, or specialised ecommerce hosting providers. You control the full stack. This gives maximum flexibility but requires DevOps expertise. Managed hosting providers like Hetzner, Platform.sh, or AWS with Terraform templates can reduce the burden significantly.
Scaling Strategies for Ecommerce Workloads
Ecommerce traffic is inherently spiky. You might see 10x normal traffic during a product drop or seasonal sale. Your infrastructure needs to handle these peaks without manual intervention.
Horizontal scaling adds more server instances behind a load balancer. This is the standard approach for Magento and Shopware deployments on cloud providers. Auto-scaling groups on AWS or Azure Virtual Machine Scale Sets can spin up new instances based on CPU usage, request count, or custom metrics.
Vertical scaling increases the resources of a single server. This is simpler but has hard limits and usually requires downtime. It is rarely sufficient as a primary strategy for high-traffic stores.
CDN and edge caching offload static assets and even full pages to globally distributed servers. Cloudflare, Fastly, and AWS CloudFront are popular choices. For Magento with Hyvä, the lightweight frontend theme reduces page weight dramatically, which means your CDN cache hit rate improves and origin server load drops. Shopify handles CDN automatically through its global edge network. For Norce-based headless builds, your frontend hosting platform typically provides edge caching out of the box.
Plan your scaling strategy before you need it. Load testing with tools like k6 or Gatling gives you concrete data on where bottlenecks appear.
Security and Compliance in the Cloud
Ecommerce stores handle sensitive data: personal details, order history, and payment information. European merchants must also comply with GDPR, which adds requirements around data residency and processing.
Data residency matters. If you sell to EU customers, your data should be stored within the EU. AWS has regions in Stockholm and Frankfurt. Azure has data centres in Sweden. Shopify stores data primarily in North America, though their infrastructure is globally distributed—check their data processing agreements if this is a concern for your compliance team.
PCI DSS compliance is required if you handle credit card data directly. Most modern setups avoid this by using payment service providers like Klarna, Adyen, or Stripe, which handle card data on their own PCI-compliant infrastructure. Your cloud environment still needs to be secure, but you avoid the heaviest compliance burden.
Basic security hygiene includes:
- Automated patching of operating systems and dependencies
- Web application firewalls (WAFs) in front of your store
- Encrypted connections (TLS) everywhere, including between internal services
- Regular penetration testing, at least annually
- Role-based access control for your cloud console and deployment pipelines
On Shopify, most of this is handled for you. On self-hosted platforms, it is your responsibility or your hosting partner's.
Platform-Specific Infrastructure Considerations
Each ecommerce platform has its own infrastructure profile. Here is what to keep in mind.
Shopify
Fully managed. No infrastructure decisions beyond choosing your plan tier. Performance is consistent. The constraint is customisation—you work within Shopify's architecture. For most B2C merchants, this is a strength, not a weakness.
Norce
Norce runs on Azure and provides APIs for commerce logic. Your frontend is separate. This means you need a clear strategy for frontend hosting, build pipelines, and monitoring. Teams using Norce often pair it with Vercel for the frontend and use Azure API Management or a gateway layer. Budget for DevOps capacity or a partner who can manage this stack.
Shopware
Shopware 6 runs well on standard LAMP or Symfony-compatible stacks. Popular hosting options include AWS with managed RDS for the database, Elasticsearch or OpenSearch for product search, and Redis for caching. Shopware also offers a cloud-hosted version for teams that prefer a managed setup.
Magento / Hyvä
Magento is resource-intensive. It requires Elasticsearch, Redis, Varnish, and a well-tuned MySQL or MariaDB instance at minimum. Pairing Magento with Hyvä reduces frontend complexity and improves performance significantly. Adobe Commerce Cloud provides a managed option, but many merchants run Magento on AWS or dedicated hosting for better cost control.
Cost Management and Monitoring
Cloud costs can grow quickly without visibility. A mid-size Magento store on AWS can easily cost 15,000–30,000 SEK per month depending on traffic, redundancy, and environment count (staging, production, QA).
Key practices for keeping costs under control:
- Right-size your instances. Many stores run on larger instances than they need outside of peak periods. Use auto-scaling to match capacity to demand.
- Use reserved instances or savings plans. If your baseline traffic is predictable, committing to 1-year or 3-year reserved capacity on AWS or Azure can save 30–40% compared to on-demand pricing.
- Monitor actively. Tools like Datadog, New Relic, or open-source alternatives like Grafana and Prometheus give you visibility into both performance and cost drivers. Set alerts for anomalies.
- Separate environments wisely. Development and staging environments do not need to mirror production sizing. Scale them down or shut them off outside working hours.
For Shopify merchants, costs are simpler—your plan fee covers hosting. But app fees, API call limits, and Shopify Plus costs for higher-volume stores still need tracking.
At Nordic Web Team, we help merchants build infrastructure that fits their actual workload—not an over-engineered ideal. The goal is reliability, performance, and cost efficiency in balance.
