  • New groups creation via JCA

With this release you can create your own groups of users via JCA. To perform this navigate to Billing > Groups, where you will see the list of already existing groups. Click the Add button in the upper panel and in the opened window specify new group Name, Type, Source Group and Description.

Source Group defines the welcome email, values of quotas and the pricing model for a new group. All these options will be copied from the source and can be edited based on the requirements.

After new group creation in Localization > Email Templates > Hivext section new welcome email with following name will appear:
hivext_welcome_for_{name of the group}.

If there is no specific welcome email for the chosen Signup Sources, the default welcome email of the chosen Type will be used as a template.

Using &group={group_name} parameter in the signup link you can configure assigning the users to a specific group. More details about setting a registration link can be found in the Signup Sources document.

  • Recharge cards managing

Recharge Cards are one-time fee service plans used for charging Jelastic accounts and sold to your Jelastic users through Cleverbridge and PBAS billing systems.

Starting with Jelastic 1.9.2 you can use the JCA > Recharge card option to configure the list of these one-time fee service plans. In the Recharge card window you can see the list of already existing service plans with information about:

  • Price (the one you state as setup fee/base price)

  • External card id (Product ID/One-Time Fee Hosting Plan ID)

  • Description

  • Enabled (availability for users)

  • Default (offered to users by default while refilling)
    Here you can Add a new recharge card and Edit or Remove the existing one.

  • Manage Application Packaging via JCA

Jelastic App Packaging is already well known and as experience shows us, it is a demanded feature. It helps the users to skip many steps of manual installation. And for hosters, it is a good way to improve the application’s distribution and sale, and to reduce application support and management costs. Now, working with Jelastic App Packaging becomes easier not only for end-users but also for hosters. In this release, Jelastic provides you with the ability to manage this feature through JCA.
Right now, we are beta testing this functionality and that is why it can be optionally enabled by adding the following parameter to your JCA link:

As a result, the Applications option will be displayed in the left menu of JCA. Using this option you can find a list of default packages provided by Jelastic and you can also add your own.

Writing the code using the given template, adding a package to the system, testing and publishing in production - all these steps can be now easily done, right in JCA. Want to attract more users? Just place a widget for automatic deployment of your project on your site or anywhere you wish, using our special code.

Resolver High Availability

To increase high availability of the system, Jelastic uses several Resolvers for receiving requests simultaneously. There can be several entry points for users' environments used at the same time. In this way the load can be effectively distributed.

The data source for all Resolvers is the Database Server (MySQL). They do not use the numerous data files located directly on the file system. Their synchronization is performed using master-slave database replication. Storing all of the data in a single place makes Resolver instances fully interchangeable in the case of any errors are in one of them. The Database Server guarantees data integrity and its easy and faultless synchronization.

Own OS template

We have built our own basic OS template - a set of packages used to populate a container. It consists of system programs, libraries, and scripts needed to boot up and run the container, as well as some very basic applications and utilities. Our OS template will be applied for all new Jelastic containers instead of Parallels VZ templates, used before. The main advantage is that all containers use RPM packages for cache only from the Jelastic repository. It makes the process of upgrading packages fully controlled and ensures that all the nodes have the same versions of packages.

Universal Adapter to integrate with in-house billing systems

The Jelastic platform has an internal billing system, Jelastic Billing, which acts as a source of primary billing data. An External Billing is fully fledged billing which is connected with Jelastic Billing to provide a full billing lifecycle for the customer, including legal payment performance. The existing external billing systems which Jelastic has integration with are Parallels Business Automation (PBA) and Parallels Business Automation Standard (PBAS). Using Universal Adapter you can integrate Jelastic Billing with your inhouse billing system (External Billing) to provide customers a unified billing interface via the Jelastic Dashboard.

GIT & SVN Auto-deploy

To greatly increase your productivity as a developer, Jelastic provides you with the possibility to set periodical automatic deployment of your project based on the changes you’ve committed via GIT/SVN repository. You can work in GIT/SVN without ever leaving it. Simply update your code, make a commit and all of the changes in your VCS project will be automatically pushed to your production environment after a specified interval of time. To set automatic updates of your project due to your commits in GIT tick the Check and Auto-deploy Updates checkbox in the Add project window and specify the interval for checking in minutes. That’s all! Just make a small configuration while adding your project to the Jelastic Cloud and continue working with your code through GIT/SVN without even coming back to our dashboard again, being sure that everything is up-to-date on your production automatically!

Adding automated bonuses after upgrade

To increase the conversion rate from trial to paid, we offer to use a bonus system after upgrade. To set the bonuses you need to navigate to JCA > Billing > Groups > Quotas and configure the following quotas:

  • - an amount of bonus based on the percentage of the first payment provided by a user after the upgrade;
  • - a number of days after sign up when the reward system starts;
  • - a number of days after sign up when the reward system ends.

After upgrade the user reaches quota and then the reward system starts. Now the user can receive a bonus percentage from the first payment ( if he converts and replenishes the account during the stated time ( In this case the refilled money goes to the main balance (cash) and the reward goes to the bonus balance. If a user has converted due to the rules of the reward system, a notification about a bonus charge will be sent. It contains full details about the amount of money put on the account: refilled, bonus and total sums.

SSO integration

Single Sign On (SSO) is intended to simplify the processes of balance refilling and opening of support tickets for all billing customers, if a hosting provider has a custom billing system. SSO to billing and support portals is the mandatory feature for the commercial launch if a hosting provider uses an inhouse billing system. The hosting provider has to implement a special SSO service that returns a one-time link to its billing and support portal for a particular user. After that Jelastic team implements the adapter for this service and enables it on the production environment.

Firewall for end users' containers

A firewall is considered a first line of defense in protecting private information. It helps to prevent unauthorized SSH access and to defend your data against various brute force or DDoS attacks, rootkits and botnets. This functionality is implemented to limit the number of opened ports on users' containers. A firewall is configured for each container which you add to your environment. Every container has its own list of necessary ports which must be opened. Also each container includes limited SSH access which is available only from an internal IP address of the Jelastic core. When a container is started a special script indicates the appropriate rules on the basis of the container type and decides if the port can be opened. Those that do not meet the specified security criteria will be blocked.

ActiveCampaign mailing system

While looking at Jelastic hosting companies that have higher conversion rate from trial to paid, we have identified that one of the influential factors is the right upgrade campaign. Instead of just sending a welcome email and then a few emails at the very end of the trial period, it is recommended to have an automated campaign that sends various types of tips and promotional messages almost every day during a trial period (obviously with the ability to unsubscribe). To achieve this we have created and released integration with the ActiveCampaign service. If you already use another service - you can probably get one of your engineers to adapt our integration scripts. If you do not have such a mailing service yet, you can easily switch on and configure using ActiveCampaign in Jelastic.

Cleverbridge billing system integration

Cleverbridge is an online billing system based on the SaaS model. It’s hosted externally from a hosting provider and built upon multi-tenancy architecture. Cleverbridge provides a single access point to all payment processing centers and doesn’t require the signing of contracts with a hosting provider. Cleverbridge allows you to build a distribution network of resellers and affiliates. In terms of Jelastic, Cleverbridge allows you to create a master account for the main hosting provider and then a list of accounts that are subordinate to it, affiliates. Affiliate management is for setting up revenue sharing models and reseller management is to offer discount ordering for special customers. From a customer prospective integration looks like our existing PBAS or PBA integrations.

Ruby Support

Jelastic has begun beta testing of Ruby hosting support. Be the first to try it out. You can activate Ruby hosting for all of the users, or for some groups or for just a specified user:

  • for separate users
    Navigate to your JCA > Users > Quotas.
    Choose a user and activate beta.enable_ruby quota by changing the value to 1.

  • for a specified group
    Navigate to your JCA > Groups > Quotas
    Choose a group and activate beta.enable_ruby quota by changing the value to 1.

  • for all users Navigate to your JCA > System settings > User Interface.
    Find the LANGUAGES_ENABLED parameter and add “ruby” to the list of available programming languages.

Note: as we are beta testing Ruby now, we recommend to only activate it for separate users. The reason behind the Jelastic Cloud and Ruby hosting cooperation is that we have a very similar philosophy - “simple in appearance, but complex inside”. Developers call Ruby a beautiful, artful language. And yet, it’s handy and practical. The same applies with Jelastic’s intuitive dashboard panel and a wide range of complex features.

Enjoy the benefits of the balance between simplicity and power with the Jelastic Cloud and Ruby on Rails. These seem bold claims, but we are sure that after trying Ruby on Rails with Jelastic you’ll agree with us.

There’s no better way to experience the true power and elegance of the Jelastic Cloud and Ruby on Rails collaboration, than to fire up your own Jelastic environment and deploy your Ruby application.

  • Container Packages Central Management and Stacks Update

    For now we centrally manage the packages for containers and perform updates of the software stacks at the hardnode by ourselves. Update of the stacks is processed automatically at all hosting platforms. After this the hoster receives an email notification with request to reboot the stacks if it is needed.
