What is Auto-Clustering. Out-of-Box Clusterization for Databases and Application Servers
In the modern world, the importance of data availability cannot be underestimated. Herewith, you want to maintain immediate access to any required information at a moment’s notice. Thus, for any production solution of any meaningful size, it is highly recommended to configure a cluster. Software clustering is the technique of using at least two instances for a service. Such redundancy not only provides reliability (the system can withstand a failure of at least one instance) but also helps to handle high load.
Based on the experience, the configuration of a cluster can be a challenging process that requires quite a lot of time investment. In order to help you out, Jelastic PaaS automates some of the most popular clusterization solutions and can perform them for you on-demand directly from topology wizard. Such automation immensely simplifies and speeds up the creation of a reliable production-ready cluster for your project.
Enabling Auto-Clustering
Currently, the following templates support the Auto-Clustering feature via the topology wizard:
- application servers — GlassFish, Payara, Jenkins, WildFly
- SQL databases — MySQL, MariaDB, PostgreSQL
- NoSQL database — Couchbase, MongoDB
- storage server — Shared Storage Container
Tip: In addition to the Auto-Clustering option in topology wizard, a number of prepackaged clusterization solutions can be found under the Clusters category of the Jelastic Marketplace.
1. Select one of the listed stacks in the topology wizard. The appropriate Auto-Clustering switcher will be available in the central part of the frame.
2. You can hover over the hint icon for additional information on this particular stack auto-clustering implementation. Within the description, you can find the Learn More link to documentation with a more extensive overview.
3. Also, after enabling Auto-Clustering, some additional configs can appear for further customization of the cluster. For example, MariaDB auto-cluster allows to choose replication Scheme and add dedicated ProxySQL load balancer exclusively for this database cluster:
