How to Create your Jelastic Environment

To host your application you need to create an appropriate environment firstly. It will be spread across a set of servers, chosen according to your app's requirements and programming language it is written in. Herewith, every instance in Jelastic environment (like database, app server etc.) represents an independent virtual machine (container).

Jelastic monitors and maintains your environment. For example, if instances need more resources, they are moved to more powerful hosts without the necessity of your manual intervention. In addition, Jelastic sends you an email notification whenever it makes any modifications to your environment.

The following guide will help you to pass through the steps of environment creation, describing the available software stacks and additional possibilities the Jelastic Cloud provides. So, proceed to the steps below:

1. Log in to the Jelastic dashboard with your credentials.

2. Click New environment in the upper left corner of the dashboard.

3. The Environment Topology dialog box will be opened. To start with, choose your programming language by clicking on the appropriate tab in the upper part of the dialog box:

4. Here you can fully customize your environment settings.

Now let’s consider each of the available blocks in more details:


If you want to set up the load balancing, simply pick the NGINX-balancer node by clicking the Balancing button (also, it is automatically enabled if you use more than one server). Then, specify the resources limits for vertical scaling of your server (fixed and dynamic amount of cloudlets you want to use) in the center section of the Environment topology window.

If you need an external IP address, switch on the Public IPv4 option (please note: this is a paid add-on).

Application Servers

Click the Application servers button.

  • In the first drop-down menu choose the application server you want to use (GlassFish 3.1, Jetty 6.1, TomEE 1.7, Tomcat 6/7, Apache 2.2, NGINX 1.6, Node.js 0.1, IIS 8 or any other one available by means of cartridge added by your hosting provider).

    You can change the cloudlet limits per server (vertical scaling) using the sliders (for fixed and dynamic amount of cloudlets separately).

    Use the +/- buttons between the application server icons to scale your server horizontally (more or less nodes).

    More info:
  • In the second drop-down menu choose the desired Engine version:

    In case of NodeJS or .NET usage, the only available version (Node.js 0.10 or .NET 4 correspondingly) will be chosen automatically.

  • If you need it, you can switch the High Availability on for your Java or .NET application server. You can also attach the Public IPv4 address to your app server, regardless of the used programming language (please note: this is a paid add-on).

    More info:


Using the Cache icon, you can add a Memcached node.

Use the sliders to change the cloudlet limits for its vertical scaling.

More info:


There are two sets of databases available: SQL and NoSQL databases.

Additional Options

There are a few additional options available: VPS, Maven and SSL.

  • If you want to use an Elastic Virtual Private Server (VPS), click on the same-named VPS icon, choose the required one via the appeared drop-down list (Centos 6.6, Windows 2012 or Windows 2008) and scale it vertically by changing the cloudlet limits.

    Note that VPS containers are provided with the automatically attached external IP address by default.
    More info:
  • To use a Maven build-node (for Java projects), click the Build icon and specify the cloudlet limits for its vertical scaling using the sliders.

    More info:

  • If you want to activate an SSL for your environment, click on the corresponding icon at the top part of the wizard frame (above topology blocks).

    Jelastic gives you an opportunity to choose between Jelastic SSL (only application server is required) and Custom SSL (application server/NGINX balancer with Public IP is required).

    More info:


In addition to the variety of available programming languages, the environment wizard contains one more special Docker tab, intended for creation of containers, based on Docker templates. Inside, you’ll find four equal blocks with different layer names to the left, where you can select any amount of Docker containers with required software (added either within just one section or to different ones).

Once a particular template’s slot is chosen (at the bottom part of the frame), you can specify the resources limits for it using the cloudlets sliders, attach the Public IPv4 address (please note: this is a paid option) or perform some basic container configurations through a separate graphic tool (Edit button).

Also, the abovementioned SSL option is available for Docker-based environments (currently only the Jelastic SSL certificates are supported).

Summary List

On the far right of the wizard, in the Resources (cloudlets) pane you will see the overall amount of selected cloudlets for all nodes in your environment, your discount, and approximate Total monthly cost.

Use the Cost details and Quotas&pricing links for getting more detailed information on resources consumption and price.

Finally, type a name for your environment and click the Create button. Your environments will be listed in the upper pane of the admin panel alongside the information about its status, deployed files and resources usage.
