The advantages of both Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) are that both service models are completely located in the cloud. Instead of purchasing hardware, networking equipment and software needed to operate enterprise-class IT infrastructure in-house, cloud computing allows users to access applications vis-a-vis the Web, via a high-quality, broadband Internet connection. In such an environment, all applications and processing occur in servers located in geographically distributed data centers.
Platform as a Service, often simply referred to as PaaS, is defined as a category of cloud computing that provides an environment and platform to allow developers to build applications and services over the Internet. PaaS services are hosted in the cloud and accessed by users simply by way of their Web browser. With PaaS, a service provider like Webhosting.net manages and delivers all your programming languages, frameworks, libraries, services and tools for your organization, so that you can create and deploy applications.
Webhosting.net also manages and controls the infrastructure, including network, servers, operating systems and storage. Under a PaaS framework your organization is additionally given control over the deployed applications and configuration settings of the “application hosting environment”.
The PaaS application hosting environment can enable operating systems, server-side scripting environments, database management, server software, support, network access and storage, tools for design and development and data hosting.
Infrastructure as a Service, often simply referred to as IaaS, is a complementary provisioning model in which enterprise-class functions are also performed in the cloud. With IaaS, an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. In such a scenario, a service provider such as Webhosting.net, owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis. As a result, IaaS is also sometimes referred to as Hardware as a Service, or HaaS.
Webhosting.net offers both PaaS and IaaS in a single, combined package called Jelastic for its enterprise-class customers. “Jelastic Platform-as-Infrastructure” combines the flexibility of IaaS with the simplicity and speed of deployment of PaaS, together in a single offering, delivering a turnkey private cloud at a fraction of the cost of other virtualized environments.
Jelastic provides a private cloud that can deploy any application (including Java, PHP, Python, Ruby and GIT) within minutes. A private cloud has been described as a computing platform that is accessible within the corporate firewall, typically under the control of the IT department. A private cloud can offer the same features and benefits of public cloud systems, but specifically addresses a number of challenges for enterprises, including control over corporate and customer data, worries about security, and issues connected to regulatory compliance.
Jelastic platform provision by Webhosting.net allows larger sized enterprises to address all of these challenges, so that they can take advantage of the raw, scalable hardware and computing power that cloud-based applications and processing can provide.
Jelastic Platform-as-Infrastructure also offers a single-point of management for both applications and infrastructure, allowing for simplified control over resources, resulting in dramatic cost savings for enterprise customers. As a result, both PaaS and IaaS constitute a distinct advantage for corporate customers.
