Tech leaders are continuously adopting cloud IT strategies to leverage the profitable advantages that include speed, agility, scalability, accessibility, flexibility and innovation. Implementation of cloud computing is more and more being considered by organizations as the most suitable and promising choice in the recent years.
According to a Gartner, Worldwide Public Cloud Services Market is expected to reach $250 billion by 2017.
Another insight discussed in “Digital Business says that, over 60 per cent of enterprises were expected to have at least half of their infrastructure on cloud-based platforms by 2018.
Enterprises are becoming more receptive than ever, by accepting cloud computing for their product, solutions, applications, and infrastructure. Due to exponential growth of adopting digital business strategy, the IT industry is observing a strong growth of cloud adoption showing a shift from legacy IT services to cloud-based services.
IDC predicts cloud IT infrastructure spending will grow at CAGR of 15.1% from 2014 to 2019, reaching $53.1B billion by 2019.
Cloud adoption necessitates cautious planning, execution and management for the long term to grow the desired results. The process of cloud implementation begins with identifying the right cloud service application or solution provider. Then, data transitioning takes place from the existing servers / web server to the cloud. Finally, a suitable automation tool is adopted to allow data migration, while giving importance to testing; to ensure that the data/software migrated to cloud is working as planned. Businesses have to evaluate the appropriateness of cloud deployment models available – private cloud, public cloud and hybrid cloud (an integrated cloud with both private and public clouds) and choose the best option to bring in line with their business goals. Similarly, there are three cloud service models namely SaaS, PaaS, and IaaS to be evaluated.
Gartner predicts that the highest growth will come from cloud system infrastructure services (infrastructure as a service [IaaS]), which is projected to grow 45 per cent in 2017.
Cloud testing – Need for it

From the essential characteristics of cloud computing, one can arrive at the number of risks immediately. The risks in cloud application development can be categorized as below-
- Load/Performance
- Security
- Availability & Continuity
- Functionality
- Testing Data Privacy
- Compatibility
- Business Logic
- Maintainability
- Interoperability
- Regulation & Compliance
To determine the required test measures, all risks have to be mapped. Firstly, conduct a product risk analysis to find out the areas that are important to test. We indicate which test measures can be taken to cover the respective risk.
Types of Cloud Testing
Functional Testing: Functional testing is performed for both remote and local applications. It involves testing all features and functions of the system/application. The different types of functional testing are; System testing, integration testing and User Acceptance Testing.
Non-functional Testing: In this, testing is done to ensure that the application meets the specified performance requirements. It includes Security testing, Stress testing, Load testing, Performance Testing, Browser testing, Latency testing, Availability testing, Business Requirement testing, etc.
Cloud Testing Tools
The accurate choice of testing tools really depends on client application architecture, context, and client requirement. Some of the most commonly used cloud testing tools have been given below.
Load Test and Performance Monitoring Tools
- Perfecto Mobiles, Keynote (Test Center Enterprise)
- Monitis, Cloudsleuth
- BrowserMob, CloudTools, GFI
- LoadStorm, CloudHarmony, InterMapper, BlazeMeter
Web Functional/Regression Test Tools
- Windmill, QEngine, Soasta CloudTest, Selenium, LoadStorm (Web & Mobile), etc.
Cloud Security Testing Tools
- Nessus (Detect Vulnerabilities), Wireshark, Nmap, App Thwack (for testing Android, iOS, and web apps on actual devices), Xamarin Test Cloud, etc.
Finally, it is true that the future for all businesses will be cloud computing on a very large scale. Thus, innovative cloud testing approaches and techniques are required to support on demand testing services in a cloud infrastructure.
