Choosing a cloud based lims: what moving the server to the vendor removes from your workload, what a cloud based lims system adds in dependency and in contract, and the questions that decide whether lims cloud hosting is the right shape for you

What changes and what does not

1. The vendor takes the infrastructure work. Server provisioning, operating system patching, database administration, backup and restore and availability monitoring stop being yours. For a laboratory with no dedicated information technology staff that is the whole argument, and it is usually a sufficient one.
2. You keep the configuration and the validation. Hosting does not configure your workflow or validate your system for its intended use. Where the work is regulated, the validation obligation remains with you, and the vendor's own qualification documentation is an input to it rather than a replacement for it.
3. Availability becomes a contract term, not a control. When the system is down you wait. Read the availability commitment, what it excludes, what maintenance windows look like and what the remedy is, and decide whether the laboratory can work on paper for that long.
4. Data location and access become questions you must answer. Where the data physically sits, who at the vendor can see it, how it is encrypted and what happens in a legal request are questions a regulated or clinical laboratory will be asked. Get the answers in writing before, not during, an audit.
5. Exit is the term nobody negotiates and everybody needs. What an export contains, in what format, whether it includes the audit trail, how long data is retained after termination and what assistance is included. Test the export during the trial rather than trusting the answer.

Single tenant against multi tenant, and why it matters

In a multi-tenant system every customer runs the same version and upgrades happen on the vendor's schedule. In a single-tenant deployment you have your own instance and can hold a version, which matters a great deal for validated systems.

Ask which model you are buying and what control you have over upgrade timing. A validated system upgraded without notice is a revalidation you did not plan.

Cost over five years

Subscription pricing converts a capital purchase into an operating cost and usually costs more in total over a long life, while removing the server refresh, the administration time and the upgrade projects. Model both honestly rather than comparing a licence figure with a monthly one.

Ask what renewal increases have looked like historically. The rate you sign is not the rate you will be paying in year four, and this is the question hosted vendors are least often asked.

Security questions worth asking specifically

Encryption at rest and in transit, access control and how vendor staff access is logged, penetration testing frequency, incident notification timelines and sub-processors. Ask for the most recent independent assessment rather than a summary page.

For clinical or human-subject data, add the data processing terms and the breach notification obligations. These are contract questions and they are much harder to add after signature.

Common questions

Is a cloud based lims suitable for regulated work?

Yes, routinely, provided the vendor can supply its qualification documentation and you perform validation for your intended use. Hosting does not transfer the regulatory obligation, and a vendor claiming it does is worth questioning.

What does a cloud based lims system remove from my workload?

Server provisioning, patching, database administration, backups and availability monitoring. It does not remove configuration, user administration, validation or training, which are the larger part of the effort in most implementations.

What happens if the internet connection fails?

The laboratory stops using the system. Ask what the documented fallback is, keep a paper or local procedure for the critical path, and test it, because a connection failure at a busy moment is when the procedure is needed and never rehearsed.

Can I get my data out?

Only as well as the contract and the product allow. Ask for a full export including the audit trail in an open format, and run it during the evaluation. This is the single most useful hour of a hosted software trial.
