This document is preliminary and subject to change.
In this document you can find all the new features, enhancements and visible changes included in the PaaS 1.9 release:
For detailed information on using any of the platform’s features, please refer to the users' documentation.
New Features
- FTP support
- Software stacks versions
- TomEE support
- MariaDB 10.0.0 support
- Caching in NGINX
- PBA integration
- Pricing System
Also 1.9 release includes the PHP improvements and other features added in previous releases.
FTP support
File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another over a TCP-based network.
For secure transmission that hides (encrypts) the username and password, and encrypts the content, it is used FTP secured with SSL (FTPS).
The platform supports both FTP and FTPS.
FTP advantages:
- fast sharing of files (applications and/or data),
- indirect or implicit use of remote computers,
- shielding from variations in file storage systems among hosts,
- reliable and efficient transfer of data etc.
To benefit from FTP with the platform, you need to meet two requirements:
- to have FTP client installed (for example, FileZilla)
- to switch Public IP for the node in your environment

TomEE support
Tomcat is the most popular open source application server among our developers, but for those of you who need more enterprise-ready server, we added TomEE.
TomEE is an all-Apache stack aimed at Java EE 6 Web Profile certification where Tomcat is top dog. Apache TomEE provides application developers with the best technology stack that can be deployed to a simple Java EE container. This application server combines several enterprise projects including Apache OpenEJB, Apache OpenWebBeans, Apache OpenJPA, Apache MyFaces and more. In one word: Tomcat + Java EE = TomEE.
TomEE is a full-blown app server, but at the same time it stays simple and avoids architecture overhead. “Less is more” is the philosophy of Apache TomEE. It delivers Java EE 6 Web Profile in the simplest way possible. So, this application server runs without any additional runtime requirements or startup time for larger applications and it’s compatible with most of Tomcat-aware and Tomcat-tested tools.

MariaDB 10.0.0 support
MariaDB 10.0 is the development version of MariaDB. It is built on the MariaDB 5.5 series with backported features from MySQL 5.6 and entirely new features not found anywhere else. And now it is supported in the PaaS.
MariaDB 10.0.0 is an Alpha release targeted on those who might want to test it.
Do not use alpha releases on production systems.
If you want to try MariaDB 10.0 in the platorm, just add it as your database while creating your environment.

Caching in NGINX
Caching in NGINX is the process of storing data in front of web servers. For example, the files a user automatically requests by looking at a web-page can be stored in your NGINX cache directory. When a user returns to a page he’s recently looked at, the browser can get those files from the NGINX cache directory rather than the original server, saving time and traffic.
So caching improves performance while accessing to a resource in two ways:
- reduces the access time to the resource by copying it closer to the user.
- increases the resource building speed by reducing the number of accesses. For example, instead of building the homepage of your blog at each request, you can store it in a cache.
With the platform, you can use caching in both NGINX-balancer and NginxPHP server using /var/lib/nginx/cache directory which was specially created for this purpose.

PBA integration
Now except PBAS, the platform offers one more Parallels billing solutions - PBA (Parallels Business Automation). It is a more full-featured set of capabilities designed for larger hosting services that offer more services or larger-scale deployments.
Parallels Business Automation is the leading hosting and cloud services delivery system used by thousands of service providers worldwide, from the largest telecom operators in the world to top hosters and providers of vertical solutions. Parallels automation delivers a combination of great software, thousands of hosting and cloud services, and the expertise to help build a highly profitable business.
Integration with Parallels Business Automation provides many abilities, here are just some of them:
ability to convert user from trial to paid right from the platform dashboard
ability to refill PaaS account right from the platform dashboard
more payment methods: except cards and paypal the payment can be made through diners club or through any bank using cash
payment method management option (add, view,set default, delete)
autorefill for direct payment plugins (Diners)

Pricing System
The platform offers a flexible system of pricing which is called hybrid. At the same time the price can be differentiated due to some specific conditions using the system of tiers.
Hybrid pricing is a combination of two pricing types when you can state two cloudlet limits at the same time.
The first limitation is a reserved amount of resources. The payment for reserved cloudlets does not depend on the amount of actually consumed resources. It depends on the first stated cloudlet limit. That means that you are going to pay for the stated amount of cloudlets each hour even if the environment consumes less.
The second limitation is a dynamic amount of resources. That means that the first limit can be outsteped for the environment to be able to consume more resources but all extra cloudlets are going to be charged due to another tariff. At the same time instances are scaled automatically up and down, so you only pay for what is actually consumed over reserved amount.
In such a way you can state an appropriate amount of cloudlets you are ready to pay per hour on an ongoing basis and also some standby cloudlet number in case of resource consumption increase.
