(The Hosting News) – Jelastic, Inc., the company behind the ultra scalable and interoperable cloud hosting platform for Java, today announced the launch of its highly anticipated PHP hosting service. Jelastic’s PHP Platform-as-a-Service (PaaS) runs applications without code changes and offers advanced options for experienced programmers.
Jelastic is known for its advanced functionality that is both easy to use, and flexible and powerful enough for experts. Unlike most PaaS offerings, it does not require code adaptation, so anyone can deploy a PHP application in the cloud in just a few clicks. However, experienced IT specialists will find the advanced features necessary to satisfy their demands. Jelastic recently won the Duke’s Choice Award, the “Oscar” of Java community, for this feat, and is proud to announce it’s accomplished the same for PHP.
“We are very excited to announce Jelastic for PHP, with the features and flexibility to host and scale complex PHP applications. We’ve made it easier than ever to develop and run PHP apps, without vendor lock-in, in the data center of your choice, worldwide,” said Ruslan Synytsky, CEO of Jelastic. “For innovative hosting companies, our channel program offers the next-level cloud services needed to compete with the big guys.”
PHP cloud hosting with Jelastic offers numerous advantages:
High Availability and Horizontal Scalability: When visitor demand requires deploying PHP applications across multiple nodes, Jelastic ensures high availability and horizontal scalability with just a few clicks. Built-in cluster management capabilities enable applications to easily scale up or down.
Smart automatic vertical scaling: Applications receive as much CPU and RAM as needed for each server node. If load increases, resources are instantly reallocated to meet demands. Jelastic users never overpay for unnecessarily large “server instances,” and do not need to manage resources.
High level of security and isolation: Each server node executes in a virtual container in complete isolation, even when it runs on the same physical server. Container isolation provides security and resource usage protection of applications from one another.
Simple cloud setup: Select (and easily switch between) PHP versions, configure PHP settings, network ports, public IP addresses, and more. Unlike Infrastructure-as-a-Service (IaaS), Jelastic manages everything for you, so you stay focused on your application and not on your environment.
Flexible for any application: Select Apache or NGINX application servers, SQL (MariaDB, PostgresSQL, MySQL) or NoSQL (MongoDB, CouchDB) databases, and Memcached. Multiple PHP extensions and most modules are available. Git/SVN integration makes deployment simple.
Application lifecycle management: Easily test, stage, and deploy applications to production without code changes and swap or clone environments for production pushes or troubleshooting.
PHP for Jelastic is currently available in the US with ServInt, Russia with Rusonyx, Germany with dogado, UK with Layershift, Japan with Tsukaeru, Finland with Planeetta, Websolute in Brazil. Developers can test their PHP applications on Jelastic for free at http://jelastic.com.

In our previous post we have emphasized that the cloud, by definition, offers minimal management or provider support to deliver the information technology infrastructure to the user. That means, the user will not undertake the lengthy process of obtaining an IT service nor she will bother with the complexities of it. What she needs is just getting her work done without having to listen to the IT jargon. She can request one or any combination of the following services:
In the IaaS case, the cloud provider offers the “computing resources” to the customers. The cloud provider can be the company’s IT department or an outside company who charges you for the use of these resources. In any case, the user receives the service: she is not bothered with the lengthy processes of obtaining a server for her accounting department to accommodate the heavy load of upcoming fiscal-year-end accounting calculations. She knows that her department will be working hard and she needs more computing power. She fills out the form, details what she wants and receives the server in some hours. When the hard times are over for her department, she delivers the server back.
In this scenario, the IT department has offered the IT infrastructure (servers, storage, network infrastructure) to the company and the accounting department used some part of it. The accounting department is (incrementally) charged by only the use of the resources for a specific time, meaning that when the hard times are over, there will be no additional charges.
If you have beared with me so far with the cloud articles, you have just caught that the company’s private cloud is offered as an infrastructure.
The question here is if anybody else can offer this service. Yes, whomever that has made the necessary investments can. You can purchase resources from providers such as Amazon Elastic Compute Cloud for deploying your own servers or just storage such as Amazon Simple Storage Service.
Platform as a Service is one layer on top of the infrastructure. The computing resources and the solution stack running on top of the resources are delivered to the customer. The solution stack here means the platform. PaaS is for companies that develop applications, databases or integration services. The typical offers are:
That also includes multi-tenant architecture, collaboration environment for application developers and reporting facilities.
There are various companies who offer different platforms:
Software as a Service offers the software, the data that the software uses and the means for allowing the user to access the service via a web browser. In many cases all the users of the service uses the same software version but sometimes a second version, most probably a beta for the upcoming release, is provided. In today’s world, almost all of the Internet users are using at least one SaaS offering, such as Google Applications, Hotmail, Evernote, Google+, Facebook.
SaaS brings the following benefits to its users:
SaaS is the top level that is reached by the cloud. All that is needed to get the job done is a web browser – the hardware and the software that is running the browser is irrelevant. This is really what the users need.
