Running a traditional content management system comes with system administration jobs that might affect the availability of service:
- installing CMS patches and avoiding breaking plug-in dependencies while doing so,
- updating staging and production systems,
- CMS and operating system updates, relaunches,
- expanding tables in the database,
- monitoring system integrations,
- fixing failed integrations,
- invalidating caches,
- re-deploying the website.
All these tasks and many others lead to planned or unexpected downtimes. Since the availability of the content to be delivered is vital for customers and employees, the unavailability of a server can cause serious damage. It is not about a single shopping transaction that fails or a small piece of important information that can’t be provided to the customer. It is worse: the customers’ trust or the employees’ motivation may be damaged in a way that has expensive long-term effects.
Therefore, planned or unplanned CMS system downtimes are no longer acceptable. The internet operates 365/24. Hence, the CMS as a content hub must be permanently available, and a corresponding service level agreement (SLA) must exist. The software architecture of SaaS CMS Scrivito is fully based on distributed, fault-tolerant web services, many critical ones on the Amazon Web Services (AWS) infrastructure. Scrivito’s modern architecture includes monitoring, self-healing, and a scaling shared-nothing architecture distributed over different data centers, also known as availability zones. The web services powered by the enterprise SaaS CMS Scrivito are accessible at the highest possible standard: this is guaranteed by AWS and included in the SLA. There are no breaks in content delivery, even during blackouts and natural disasters. SaaS CMS Scrivito is even used in critical infrastructure like in aviation and medical environments.
Some Scrivito customers have been running their system for 5+ years without experiencing a single minute of downtime. Thanks to the architecture of the cloud-native SaaS CMS Scrivito, organizations can expect to measure a service availability of over 99.95% per month.
