Infrastructure

Server support and systems administration

Windows and Linux systems that are built carefully, kept current and understood, rather than left running and hoped for.

Sound familiar?

  • A server is out of support and nobody wants to touch it.
  • No one knows exactly how your systems are configured.
  • Performance is poor and the cause is unclear.

Many business servers are held together by undocumented changes and a fear of restarting them. Systems administration brings them back under control through a clear inventory, safe patching, sensible access and monitoring. New builds are configured in a repeatable way so that they can be recovered or replaced with confidence.

Common questions

Do we still need a server, or should we move to the cloud?

It depends on your applications, connectivity and budget. Many small businesses can retire on-premises servers, while others benefit from keeping one. You will get a recommendation based on your setup.

Can you take on a server nobody has documented?

Yes. The first step is a careful audit of what is running, followed by backups and documentation before any significant changes.

What do you do about an end-of-life server?

Unsupported systems no longer receive security fixes. Kaynai can plan an upgrade, a migration or a retirement, with isolation measures in the meantime.
