Cloud is a tool.
Architecture makes the difference.

No. Applications, data and services can run locally, in a private cloud, as SaaS or in a public cloud. A deliberate combination is often the best fit.

When business applications, large data volumes, low latency, predictable cost or specific integrations support that choice. Operations, backup, maintainability and a recovery path still need to be planned.

Hybrid connects local or owned infrastructure with cloud services. Data, identities, applications and access are deliberately divided between operating locations.

A private cloud provides standardised, often virtualised resources for one organisation. It can run on site or in a data centre and remains clearly assigned organisationally.

Software as a Service means using an application as an ongoing service. The provider largely handles operation and updates, while configuration, permissions, data and integrations remain company responsibilities.

No. It can avoid upfront investment and scale flexibly, but it creates recurring costs. Users, storage, data transfer, additional features and administration must be considered together.

No. Providers can offer powerful security functions. Misconfigured permissions, missing MFA, unsafe sharing and unclear backup arrangements still create real risks.

Yes, when performance, support, security and recoverability fit the purpose. Introducing cloud services does not automatically require replacing working infrastructure.

Technically, often yes. It only makes sense when responsibilities, identities, file locations, licences and the user experience do not become unnecessarily complex.

Yes. Both productivity services can be planned, migrated and administered. The choice follows working practices, applications, contracts and the existing environment.

Examples include scalable applications, development environments, data processing, identity services or infrastructure that is not sensible to operate locally. The specific service must fit the task.

Cloudflare can provide DNS, protection, acceleration, access control and other infrastructure services. The useful functions depend on the website, applications and security design.

That depends on the operating model. Local services may continue, while SaaS services usually cannot be reached. Secondary links, mobile fallback and defined emergency procedures can reduce the impact.

First, we establish what recovery the provider already offers. Versioning, separate backups, retention and tested recovery are then added to match the risk.

Depending on requirements, yes. Retention and recycle bins are not the same as an independently planned backup. The need follows the data, retention periods, failure scenarios and required recovery path.

Through central identities, roles, MFA and clear administrative responsibilities. Joining, moving and leaving employees must be handled as an ongoing process.

No. Phased migrations often reduce risk. Pilot groups, separate data areas and defined fallback options make the transition easier to control.

Yes. Powerful workstations or servers can remain local and be used remotely, while communication and other services operate in the cloud.

Depending on the requirement, through site-to-site connectivity, secure internet access, SD-WAN, VPN or directly protected cloud access. Network, identity and failure behaviour are planned together.

In many cases, yes. The contract, tenant, licences, roles, billing and current responsibilities are clarified first. Changes follow only after a controlled handover.

Often, yes. Before moving back, data export, formats, applications, identities, integrations, operations and cost are reviewed. An exit is easier when data and dependencies were documented during the original introduction.

By inventorying users, plans, storage, add-ons and actual use. Unused accounts and overlapping services can then be removed without indiscriminately disabling required functions.

Yes. Depending on collaboration, data volume, sharing and operations, local file services, NAS, private cloud or products such as Nextcloud may fit. Synchronisation, permissions, mobile access and backup must be considered together.

Yes. Mailboxes, files, calendars, contacts, identities and sharing can be moved in controlled stages. Self-hosted mail is technically possible too, but requires ongoing responsibility for deliverability, security, backup and operations.

Beyond base licences, include user growth, storage, data transfer, add-ons, backup, support, administration and possible exit costs. A useful comparison therefore covers several years and internal operating effort.
