By clicking on “change environment typology” you can change all the settings for the Cluster, both to scale the resources allocated to it (vertical scalability) and to increase or decrease the number of nodes (horizontal scalability). You can also set limits for automatic scalability so that your costs are always under control.
This scalability is made possible thanks to Docker container technology, which means you can run applications according to the Container as a Service model (CaaS), and Cloudlets, units corresponding to 400Mhz of CPU and 128MB of RAM, which you can use to define the size of your environments, thus ensuring maximum efficiency in terms of the resources used without any waste caused by services not being used.
In particular, vertical scalability is especially flexible thanks to the differentiation between reserved cloudlets (which are always active, regardless of workload) and dynamic cloudlets, in other words the maximum amount of resources that can automatically be assigned to the node if needed.
Added to this is horizontal scalability, which can be automated according to configurable triggers: in practical terms, it means that, for example, the number of nodes can be increased or decreased if the system registers a load on the application server above or below a certain threshold continuously for a set number of minutes. The service is available on a pay-per-use basis on an hourly basis, as well as in preconfigured plans, with fixed monthly fees.
CONFIGURE YOUR ENVIRONMENT
Jelastic Cloud offers a convenient solution to all your needs with peak traffic, making scaling possible even on the database, so that you can always rely on the highest performance levels, thanks to an automatic horizontal and vertical scalability system, based on traffic.
Each environment is configurable as a whole and for core components, and can be fully monitored, from configuring SSL certificates and DNS records to creating complex, automated node structures. The pre-configured WordPress cluster is available on the Marketplace with a series of installation options, including the SSL certificate to guarantee a highly secure connection and the MariaDB Galera cluster. It only takes a few minutes!
