Scalability: Cloud-based mobile application testing allows testing teams to scale up or down their testing resources quickly and efficiently. They can easily add or remove testing resources based on their current requirements. As a result, developers can complete the testing process faster and more effectively, and adapt their resources to suit a project of any size or type.

Cost-effectiveness: Cloud-based mobile application testing teams do not need to invest any of their budget in hardware and infrastructure. The entire testing process can be done in the cloud, using rented resources on a pay-per-use basis. In this way, money and resources can be saved, and the process is cheaper and more cost-effective. On-premise testing is a capital-intensive enterprise. You would first have to pay to acquire and set up the hardware, and then cover ongoing operational costs. Instead of focusing on testing and fine-tuning a new app, the QA team would waste a lot of time customizing and reconfiguring your setup to operate on each new app. Imagine if an app needed to be tested across five different OS versions and 50 different phone models. Bringing all that testing capacity onto your premises would be incredibly expensive. There are so many variables involved with app testing, from the number of screens to the types of testing to the number of test cycles and the number of devices, among others, that it is difficult to estimate a general price, but suffice it to say that applying all these variables in the cloud, as opposed to on your own hardware, will yield incredible savings.

Flexibility: Testing teams have the ability to set up customized testing environments with relative ease. Whatever their specific user scenario and network conditions may be, they will have the resources they need to create an environment that perfectly suits their needs. On-premise infrastructure is likely to have inherent limitations that may inhibit the expansion of projects outside of the original specifications for which the system is designed. When you test a new app, you may have to upgrade your on-premise system, generating more costs and taking up more preparation time.

Collaboration: With cloud-based mobile application testing, your team, even if it is spread across many different locations and time zones, can collaborate effectively. They can easily share test results, collaborate on testing activities, and communicate with each other in real time. Collaboration helps teams to work more efficiently and effectively. On-premise testing is more of a closed system, in which collaboration is limited to team members working on-site. Of course, remote collaboration is possible with on-premise systems, but, again, this would entail additional costs.

No maintenance or updates necessary: Without any on-premises devices, you will not need to worry about repairing hardware, updating software, or ensuring the right device mix.

Security: Testing data is stored in the cloud, potentially making them accessible to more people, and thus susceptible to cyber-attacks. These security concerns do not make cloud-based testing unfeasible, however; it just means that adequate security measures need to be put in place. Effective encryption is usually enough to ensure that data is kept safe. A good cloud operator that provides a platform for data-sensitive functions, such as app testing, should provide end-to-end encryption that protects all data and strictly limits access only to authorized personnel.

Reliability: Testers need to be able to trust that the cloud infrastructure they are using is reliable. Downtime or technical issues can disrupt the project and lead to unnecessary and unplanned costs.

Data Privacy: Cloud-based mobile application testing involves sharing sensitive data with third-party service providers. Any time data is shared, it is potentially vulnerable, which may raise concerns about data privacy and data protection. Again, cloud platform operators have an obligation to ensure data security through measures such as encryption, and strict configuration principles. Users can further strengthen security by protecting all the devices they use to access the cloud, using careful permission and password management, avoiding the use of public Wi-Fi connections, and the use of up-to-date anti-malware products.

Integration: Cloud-based mobile application testing may require integration with different systems and platforms, such as the testing framework, automation tools, and testing tools. Integrating all these different parts may require additional configuration and setup, which may be time-consuming and complex.
