When a service is distributed to multiple independent servers, an individual server receives fewer requests. This improves not only the throughput or latency but also the fault tolerance. Should one of our <a href="https://208.fi/en/term/dns/">name servers</a> slow down or hang, others would guarantee continued service.</p> <p>In theory, the source of a disruption does not actually matter. By far, the most probable <q>fault</q> of our name servers ought to be the regular update of service containers and the content, which will disable one server at a time for a short duration. Because the function of the updated device will be checked before proceeding to the next one, the update can harm at most one device. If necessary, it can be rolled back to the pre-update state. During this time, other servers will keep the service available. In our case, all this happens automatically in <a href="https://208.fi/en/blog/private-gitlab-erp/">our GitLab based ERP system</a>.</p>https://208.fi/en/blog/private-gitlab-erp/Sat, 12 Sep 2026 12:45:00 +0300https://208.fi/en/blog/private-gitlab-erp/<p><a href="https://projectorganisationhelsinki.fi/en/continuity/">Business continuity management</a> is one of our lines of business. How do we practice it ourselves? The <q>brain</q> of the company is an <em>enterprise resource planning</em> (ERP) system that is in charge of all business related activity, such as the publication of this blog post.</p> <p>Based on prior experience we chose GitLab. Not the service <a href="https://gitlab.com">gitlab.com</a> but an <a href="https://docs.gitlab.com/install/">installation</a> of the open source software in our private network.</p> <p>To ensure data security, we run our own LDAP service and private key infrastructure (PKI). The containers of all services are built based on GitLab pipelines and schedules in closed <code>gitlab-runner</code> containers running in an isolated environment. Situational awareness is provided by a centralised logging service. This is also how the <a href="https://208.fi/en/products/gitlab/">GitLab service</a> that we offer to our customers works.</p>
