Cloud computing is one of the most hot topics[1] used now a days which will help enterprises especially smaller ones to reduce the cost and increase efficieny.If we consider switching from the data centers to the clouds there are lot of benefits including the cost reduction and resource utilization. There are three models of cloud services, software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS).

Firstly, Software as a service is the most used option for smaller enterprises if they are looking to convert to cloud. It uses the internet for delivering the tools but they don’t manage that in this, they are managed by third party vendor. Most of the applications in the sass kind of service will run through the browser. This will help in reducing the time and also reduces the cost spend by the enterprise in tedious tasks such as installing and managing the data centers. Salesforce is the primary example for this kind of cloud

Business process the board is a methodology that intends to make an organization's work process increasingly compelling, proficient and versatile to new advancements. This sort of work process empowers organizations to be progressively adaptable and to diminish their spending.

Conventional Business Process Management Systems (BPMS) coordinate business procedures and monitor running occasions of these procedures. A BPMS arranges the execution of a business procedure bit by bit. Each procedure occasion is checked by the BPMS and gives clients experiences into every procedure progress and show on the off chance that they are finished effectively, or if they have smashed. If there should be an occurrence of an accident, the BPMS indicates where the procedure had issues. By observing, assessing and recognizing where business procedures come up short, organizations have the chance to act proactively and upgrade their procedures. This will at last lead to lower expenses and better consumer loyalty.

Business Process as a Service (BPaaS) is a business process outsourcing model which is based on the cloud computing service model [1]. It is a type of horizontal or vertical business process. BPaaS implies that the business process is being automated through a remote delivery model. The pricing model of BPaaS is consumption-based or subscription-based. As a cloud service, the BPaaS model is accessed via Internet-based technologies.

Like any other cloud services BPaaS also suffers from the threat. The transition to cloud service slashed costs but at the same time also allowed easy access to business apps from any location. This has increased attack surface [1]. Before attackers had to gain access to the corporate network in order to attack applications. With the introduction of cloud, malicious users can now easily attack from any location and any device [2]. BPaaS organization must rely upon a vendor to implement storage defense and fix vulnerabilities that arise quickly.

In order to concentrate on their core business, companies often outsource non-core activities. Such as payroll or IT incident management, to a service provider. This is usually referred to as Business Process Outsourcing (BPO) [3]. Traditional BPO becomes BPaaS when the outsourced business processes are delivered by service providers using the cloud computing paradigm [2]. Companies access their outsourced processes using standard internet technologies, such as web browsers and mobile apps. In addition, the Migration of large data might for the result in significant cost. New businesses and small firms could like IaaS to evade dispensing time and money on getting and making equipment and code. Bigger firms could like better to hold total administration over their applications and framework; in any case, they require to purchase exclusively what they truly expend or need. firms encountering rising simply like the quantifiability of IaaS, and that they will correction out explicit equipment and code just as their needs advance.
