Arc
A pre-built headless platform with multi-region load balancing, zero-downtime deployments and proactive anomaly detection. Greenfield builds go live in roughly 10 to 15 days, inside your own Azure tenant.
Legacy Sitecore XP and XM carry years of customization, and the platform work around them never gets simpler on its own. Dataweavers managed hosting runs your DXP inside your own Azure tenant, with SLA-backed uptime and a 24/7 operations team. Sengo is a Dataweavers partner: we architect the move, migrate the workload, and stay accountable for what runs on top.

Automated platform management for Sitecore XP and XM on PaaS, and for Optimizely CMS on Azure. Upgrades, disaster recovery and cost visibility stop being quarterly firefights.
On-demand incremental static regeneration for Next.js. Content published to Sitecore Experience Edge appears immediately, with no rebuild and no cache guesswork.
We design the target platform before anything moves: environments, networking, identity and release flow. That decision belongs inside a wider upgrade plan, not in isolation.
Years of XP and XM customization rarely lift cleanly. We sequence the move onto Dataweavers managed hosting, decide what to keep, rebuild what should not survive, and cut over without a weekend outage.
Already running on Azure? We review architecture, security posture, release process and cost before you commit to a platform change you cannot easily undo.
We bring your developers and content teams onto the new release flow, so the platform never depends on the one person who remembers how the pipeline works.
We tune performance, caching and Azure spend after go-live, because the first month of real traffic always disagrees with the plan.
Dataweavers operates the platform. We stay accountable for the Sitecore build running on top of it, in English and in French.
Platform comparisons
Side-by-side comparisons with fair verdicts, pricing models and migration paths.
Fusion covers Sitecore XP and XM on PaaS, plus Optimizely CMS on Azure. Arc covers headless implementations and works with Sitecore, Optimizely and Contentstack. Spark adds on-demand regeneration for Next.js front ends publishing through Sitecore Experience Edge.
Yes. Dataweavers deploys into your Azure subscription rather than a shared vendor estate, so infrastructure and data stay under your control and your compliance regime. Their published stack covers web application firewalls, DDoS protection and role-based access control.
This is the common case. Years of customization make a jump to SaaS look impossible, so the estate stays put and the operational load keeps growing. Dataweavers managed hosting stabilises the platform in Azure first. The migration decision then happens on evidence rather than under pressure — which is the same posture we bring to any upgrade.
Yes. Sengo partners with Dataweavers to deliver enterprise Sitecore on Azure, alongside our implementation partnerships across Sitecore, Optimizely, Contentful, Storyblok, Kentico, Coveo, Netlify and ai12z. Holding partnerships across the stack is exactly what lets us tell you when a different answer fits better.
If you are moving fully to a vendor-run SaaS DXP and have no requirement to keep infrastructure in your own Azure tenant, a managed platform layer adds cost without adding control. The same is true for a small single-site estate that never justified a dedicated platform team. We will say so rather than sell you the layer.
