Your Jelastic environment is spread across a set of servers that hosts your application.
Jelastic monitors and maintains your environment. For example, we will move instances that need more resources to more powerful hosts. Jelastic sends you an email notification whenever it makes any modifications to your environment.

Create your Jelastic environment
To create your Jelastic environment, do the following steps:

- Click the button OFF/ON under the option Requests to switch on/off SSL.
- If you need to distribute the load switch on the balancer nginx by clicking the button under SSL (it is automatically enabled if you use more than one server). Specify cloudlets limit for vertical scaling in the middle section of Environment topology dialog box. If you need external IP address switch on Public IPv4 (note that this service is on a paying basis).
- Under the balancer the runtime execution container (REC) is placed.
Click the REC to see Application logic section in the middle area of Environment topology dialog box. Change the cloudlet limit per server for vertical scaling.
Click the second and the third REC or use +/- buttons between them to change horizontal scaling. Also for that you can use Horizontal scaling option in the Application logic section.
- If you need switch on High Availability and Public IPv4.
- In the first drop-down list under the RECs choose type and version of application server (Jetty6, Tomcat6, Tomcat7, GlassFish3) or use Software option in the Application logic section.
- In the second drop-down list choose JDK version (JDK6, JDK7) or use the option JDK version in the Application logic section.
- To build a node click the button Maven and specify cloudlet limit for vertical scaling in the middle section of theEnvironment topology dialog box.
- Click the next button to activate SQL Database. Choose necessary database from the drop-down list: MariaDB, MySQL 5.0, PostgreSQL 8.4. Specify cloudlet limit in the middle section of the Environment topology dialog box. If you need switch on Public IPv4.
- Click the next button to activate NoSQL Database. Choose necessary database from the drop-down list: MongoDB 1.8, CouchDB 1.1. Specify cloudlet limit in the middle section of the Environment topology dialog box. If you need switch on Public IPv4.
