IAAS (Infrastructure as a Service)

Foundation to enterprise cloud consulting services, IAAS enables Cloud service buyers to rent or lease a virtual space on a server with the help of an IAAS provider, instead of purchasing space in an expensive data center or server. They will have access to the data server via the internet. They have to bear cost only for those resources used by them, such as RAM, Processor, Server, or Storage space. The major benefit of renting a space on a service is you do not have to bear the expenses in case of hardware-software failure.

Much of the time, companies or people regularly deal with their own virtual Cloud server data management centers, systems and (the cloud supplier deals with the equipment, systems, and virtualization layer) applications, including upkeep of the product and OS condition. The IAAS supplier assumes liability for the equipment and plays out all the support to guarantee the servers run effectively. Since an endless number of custom applications can be produced and sent and keep running on IAAS, it winds up noticeably unimaginable for a cloud specialist organization group to oversee and investigate the majority of the product and equipment. CSS Corp is one of the companies in cloud infrastructure service providers.

SAAS (Software as a Service)

One of the four wings of Cloud Computing Services, SAAS (Software as a Service) is a Cloud Computing software distribution model wherein the third party hosts applications and facilitates them for customers with the help of internet. It helps the organizations to get rid of the burden of running or installing applications on their server space, thus saving both their time and storage space on the server. Some of the benefits of SAAS are:

#1 Flexibility in terms of payment

Instead of buying a separate software, and a hardware to support it, prospects can subscribe to SAAS by paying a certain fee on a periodical basis. Moreover, they can unsubscribe from such services anytime as they wish without having to worry about losses.

#2 Automatic Updates

The fact that SAAS provides automatic updates to customers relives the businesses of the responsibility to buy new software packages-update and patch management tools. As a result of it, the decreases the dependency level of the IT team to a large extent, and they can focus on their core responsibility.

#3 Fair Accessibility

What you need to have access to the software is an Internet-enabled gadget with location. Since companies have to depend on an external body for the maintenance of the software, any disruptions in the software or bug can damage the experience of the customer- this is one of the disadvantages of SAAS. Further, the company can create its software tools as per the customization requirement and integrate them with the SAAS offerings to ensure smoothness and efficiency in the operations.

PAAS (Platform as a Service)

PAAS (Platform as a Service) is a form of cloud computing which delivers Applications on the internet. In this type of cloud computing, a cloud supplier provides equipment and programming tools - typically those required for application improvement - to its clients as an administration. A PAAS supplier launches both the software and hardware on its own servers. Thus, PAAS liberates clients from incurring cost on in-house software and hardware requirements

Though PAAS does not form the entire infrastructure of a company, a PAAS provides the company with certain key benefits such as Application hosting, operating system, middleware like servers, defining user access, and then add finally add the application to the existing application management database. However, PAAS carries few disadvantages with it. In case, the provider comes up with a roadmap to change or modify its servers or the technology itself, the company may have to undergo changes according to the changes adopted by the provider. For instance, if the provider changes a programming language, the company will also have to bear these changes by changing the language. In addition to this, the company may face downtime during the disruption or developmental process of the system by the provider.

PAAS is one of the four main classifications of Cloud Computing, the other three being IAAS (Infrastructure as a Service), SAAS (Software as a Service) and TAAS (Testing as a Service). Salesforce.com, being one of the significant providers of CRM services, is a popular PAAS provider to companies.

TAAS (Testing as a Service)

As the name itself suggests, TAAS (Testing as a Service) is cloud computing model wherein the testing activities pertaining to the business of an organization are conducted by the outside vendor, which ultimately saves the time and money of the company by freeing the company of these activities, and making them focus on their core business instead. Many companies- especially e-commerce companies- outsource their testing services to outside vendors as the process of testing involves more time consumption, employees engagement with the process unless the testing is successful, and deployment of other resources- which may deviate the company from focusing on their business.

Despite the company outsourcing its testing services to an outside vendor, it may still like to test a few of the applications on its own as the need arises. It may also involve meeting consultants to provide support to employees or outsource the entire wing to the vendor itself- the choice is up to the company. Some of the testing services that are outsourced to vendors by companies are performance testing, regression testing, security testing, applications testing, ERP testing along with testing and monitoring of other cloud-based applications.
