2) IaaS computing platform model is dependent on internet availability. 3) It is also dependent on the availability of virtualization services. 4) IaaS cloud computing platform can limit the user privacy and customization options. Some pinpoint about IaaS cloud computing layer IaaS computing platform cannot replace traditional hosting method but it provides more than that and each resources which are used are predictable as per the usage. IaaS cloud computing platform may not eliminate the need for an in-house IT department. It will be needed to monitor or control the IaaS setup. IT salary expenditure might not reduce significantly, but other IT expenses can be reduced. Breakdowns at the IaaS cloud computing platform vendor's end can bring your business to at the halt stage. Assess the IaaS cloud computing platform vendor's stability and finances. Make sure that SLAs (i.e. Service Level Agreement) provide backups for data, hardware, network and application failures. Image portability and third-party support is a plus point. The IaaS cloud computing platform vendor can get access to your sensitive data. So, engage with the credible companies or organizations. Study their security policies and precautions. Amazon Web Services, Tata Communication Cloud Computing Platform as a Service (PaaS) is a developer programming platform which PaaS cloud computing platform is created for the programmer to develop, test, run and manage the applications. A developer is able to write the application as well as deploy it directly into this layer easily. PaaS extend and abstract the IaaS by removing the hassle of managing the individual virtual machine. In PaaS cloud computing platform, back end scalability is handled by the cloud service provider and the end user does not have to worry about to manage the infrastructure. All the infrastructure to run the applications will be over the internet. Advantages of PaaS cloud computing layer
