Shorter term recurring capital and maintenance costs include servers and networking infrastructure such as firewalls, routers, switches, along with the building infrastructure such as the air conditioning units. Objective In our last chapter, we discussed Software as a Service.Here, we are going to learn about Platform as a Service (PaaS), a type of Cloud Computing. Cloud early, cloud often: Four words to say that now is the time to embrace cloud services. Exploring advantages and disadvantages of Cloud: IAAS PAAS SAAS by Mark Satterfield Cloud service providers are in the news every day. SaaS services are usually available with a pay-as-you-go (which means subscription) pricing model.

PaaS stands for ‘platform as a service,’ providing developers with a complete environment for developing and deploying apps over the internet. Configuration is simple: Create an email address, secure it with a password, and then transact with emails. Due to rapid elasticity, the business is not at risk of purchasing and maintaining large unused data centers. There is always a learning curve but there are tremendous benefits of moving to these platforms. The Host company provides the physical security to the servers and data center.

First, we’ll define the continuum of primary “as a service” technologies. Platform as a service (PaaS) is essentially a layer between infrastructure as a service (IaaS) and software as a service (SaaS). Examples of PaaS services are Heroku and Google App Engine. SaaS, Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) are the three main categories of cloud computing. In yesterday’s model of hosted computing, the IaaS model would be where the customer has direct control of the hardware that is in a “private cage” in the service provider’s data center. The drawbacks are a little less clear cut, however, and generally are specific from one product to another based on the perspective of individual companies and their respective needs. Itâs like having a set of tools that you can use for constructing the item you need. SaaS vs. IaaS vs. PaaS vs. on-premise: Whatâs the difference?

The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. Also, it has a minimum service from its service provider, since it is also responsible for operating systems and certain licenses, such as databases. As with SaaS and PaaS, IaaS services are available on a pay-for-what-you-use model. In PaaS solutions, the service provider offers the platform or the operating system in the form of a service and is in charge of managing it … In addition, once the application has been deployed it is easy to make updates, so long as there is an internet connection.

Despite Iaas being cost-saving, having on-demand scalability, running even when the server is down, it has some disadvantages as well in terms of security control for the enterprise, upgrade and maintenance. We believe that clear and transparent workflow is a key to success. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).
