Read guideRecommended reading order
1
Choose the platform
Start with data center, SLA, colocation, VPS, dedicated server, Cloud Pro or private cloud.
2
Plan migration and compliance
Then verify DNS, mail, SSL, backup, service window, rollback and GDPR/NIS2 requirements.
3
Match the sector or problem
Use sector pages and problem pages to connect the infrastructure decision with real business workloads.
4
Operate and monitor
Finally plan administration, backup/DR, diagnostics, documentation and periodic reviews.
First architecture decisions
Then migration and operations
Parallel DNS and mail checks
Frequently asked questions
Where should I start in the DataHouse knowledge base?
Start with the infrastructure decision: data center, colocation, dedicated server, VPS, Cloud Pro or private cloud. Then move to migration, DNS, mail, backup, compliance and diagnostics.
Does the knowledge base replace a service proposal?
No. The knowledge base organises technical decisions and links to DataHouse services, configurators and tools, but it does not replace individual sizing, pricing or architecture work.
How should I use problem pages and sector pages?
Use problem pages for tasks such as relocation, backup, NIS2/GDPR, accounting systems or KSeF, and sector pages when the workload belongs to finance, public administration, healthcare or another regulated environment.
Will DataHouse build an IT and data-center glossary?
Yes. The roadmap now includes a glossary for data center, cloud, networking, DNS, mail, security, backup, virtualization and compliance terms.
