How Platform As a Service Can Transform Businesses
Cloud computing is one of the most common forms of service delivery in the enterprise. There are three basic categories of cloud services: infrastructure-as-a-service (IaaS); platform-as-a-service (PaaS); and software as a Service (SaaS.) Each offers differing degrees of flexibility and control. They each have their pros and cons. IaaS and PaaS offer the lowest cost per application, but also the greatest degree of control and customization. SaaS is significantly more expensive, but provides access to a large base of expertise and technology.
IaaS is a concept of offering on demand delivery of applications, services, and hardware within an integrated platform. This platform is supported by a number of industry-standard interfaces, which allow customers to use common applications from various providers without requiring the developer to learn and write code for each. Platform as a Service is based on the idea that applications written for a web browser can be accessed through a web browser using the same language. Platform as a Service is an offshoot of the more general-purpose Internet-based software development models, such as HTML, PHP, Ruby on Rails, and ASP. It allows customers to rapidly develop new applications without needing to understand and write code for each.
In contrast to IaaS, PaaS is a suite of products that combine the benefits of IaaS: its platform-as-a-service model and a number of middleware development tools. Because PaaS consists of a number of products, each with its own independent component and dependency, it can be more difficult to deploy. Middleware development tools are used to integrate the different aspects of a platform. For example, a CRM may use an Adobe Connect plug-in, an ASP application may use an Extensible FXPanel plugin, and so on. Middleware vendors offer their plug-ins and extensions at an affordable price.
One of the primary advantages of using middleware development tools for a platform as a service platform is cost. Since middleware is written in languages other than the platform’s native programming language, the vendor’s costs for developing it are correspondingly lower. These savings are then passed on to the customer, who pays only a portion of the total cost. The vendor maintains and updates the platform’s source code in a timely manner, while offering customers support for issues they might have. In addition, a vendor who offers a platform as a service can provide technical support for its own applications and for those of third-party customers.
Another advantage of using a platform as a service model is portability. Because the applications hosted on the platform are written in a user-friendly programming language, many developers find it easy to write and deploy applications once they have learned how to do so. By being easily customizable through a GUI, it allows businesses to quickly move from one platform to another whenever the need arises.
The use of a cloud-based platform also means that security is provided at the service level. The need for security is not at a premium because users do not need to be connected to the underlying server in order to run their apps. Rather, all that is required is that they have an account with the provider and that their security requirements have been fulfilled. Thus, even if a business does not have a dedicated server, it can still use a cloud-based platform. Moreover, developers can continue to work on the platform while others are busy working on their servers.
Platform as a Service allows companies to run mobile and web applications with fewer users and resources than would otherwise be necessary. This results in operational costs going down, because there is no need to rent extra computers or hire additional staff to man these machines. Furthermore, by allowing for easy updates and alterations, it can be expected that new applications will become available. Thus, it is likely that application development tools will begin to play a more prominent role in business IT services going forward.
With the right cloud computing platform, a business can expect to reduce costs, eliminate waste, improve productivity, and increase agility. These improvements can result in fewer repetitive tasks being performed, and this can have a significant impact on profitability. This also means that more business owners will have the time and resources available to focus on building a stronger business. The right platform as a service can help to create a positive impact on any business, regardless of the size or industry that it serves.
