Increased scalability, reliability, security

In setups running high-quality applications, application servers and database servers are separated from one another. This design gives you freedom in terms of scalability, reliability and security. In addition to the operation of the application servers, noris network of course also takes over the operation of the databases in its data centers.
noris network supports virtually all common SQL and NonSQL database types running in architectures that are precisely tailored to your needs, such as Active / Active, Active / Passive, AlwaysOn, or RA clusters.
Examples of databases currently run by us:
- MariaDB on Galera clusters
- MS SQL
The databases and database clusters are installed and configured by our IT experts. They monitor the entire system on 24/7 basis and operate it as part of an active update, patch, capacity, and incident management. In the case of high-availability clusters, the database architecture ensures that no transactions get lost in the event of an error condition. In less complex architectures, a consistent state of the database is restored from the backup.
With the operation of your Oracle databases we offer you flexibly scalable solutions. In doing so, we fall back on three different variants:
single node system
We set up and run an Oracle instance on a node. This is the simplest and most cost-effective way to have your orcale database run in safe hands.
RAC (Real Application Cluster)
We are also happy to set up a whole cluster for you! In this way we enable you to be fail-safe: but how? Several nodes of a cluster access the same database. If one node fails, the others take over its functionality.
data guard system
We install and operate one or more other Oracle instances. This means that all changes to data can be sent to a spatially separated database. This additional instance can then take over operation in the event of a planned or unplanned outage. This ensures continuous operation. In this variant, Active Data Guard can be used optionally, as long as the additionally required license is provided.
