Easy ways to perform Cloud Testing

  1. 1.     Cloud testing is a form of software testing in which web applications use cloud computing environments (a "cloud") to simulate real-world user traffic

Principles of cloud computing – “On demand availability”, “As a service” and “Pay for the usage”.

  1. 2.     Cloud testing typically involves monitoring and reporting on real-world user traffic conditions as well as load balance and stress testing for a range of simulated usage conditions.  
    Cloud testing services from companies can conduct a complete analysis of a company’s cloud computing strategy and provide the results to the company in the form of interactive real-time dashboards that detail conditions under both existing and simulated peak usage.
           The cloud has mainly three types of delivery models or components that provide “as a Service”      capabilities:
    • Infrastructure as a Service (IaaS): This is the most fundamental layer which forms the building block of the cloud. It mainly comprises of physical resources such as Storage, Network devices, compute servers, etc. All these computing resources are available on demand, where a user pays as per his usage.
    • Platform as a Service (PaaS): The central layer in the cloud Is the platform. Here there is no control over the underlying infrastructure but you can access the deployed applications. Hence this provides the entire run time environment on demand which could be a development or test environment. Hence in this model, most commonly you would have a VM that contains the complete environment like OS, required middle ware, etc. available when you need it.
    • Software as a Service (SaaS): The topmost layer here is the application layer, which is generally visible to any user. Here, applications / products are available to the user on demand via the internet. Hence instead of having to acquire licenses for a particular user, this proves to be the most cost effective way of making sure that the license is always in use. Examples of this are Gmail, Google docs, Photo shop, etc.
    Types of cloud
    There are 3 types of cloud formations: public, private and hybrid clouds:
    • Public clouds are where services are available to everyone, where the resources are allocated and provisioned dynamically as per request.
    • Private clouds are generally managed within firewall rules of a particular organisation and are available only to the users within the company.
    • Hybrid clouds are a mixture of private and public cloudsOrganisations can decide what services they want to expose to everyone and what services they want to expose to only the users within the organisation.
    Cloud testing refers to testing of resources such as hardware, software, etc. that are available on demand. Even the testing here can be viewed “as a service”. For cloud offerings it’s essential to make sure that the service (product) not only meets its functional requirements but also nonfunctional requirements. With the range of applications in the cloud it is now becoming essential to develop cloud testing strategy.

    Cloud computing has today become one of those “big bangs” in the industry. Most organisations are now leaning to adopting the cloud because of its flexibility, scalability and reduced costs.
    Using the cloud for testing is immensely helping organisations to acquire the required tools, software licenses, infrastructures at a very low cost without having to set it up themselves and then worry about its maximum utilization.
