• Cloud Computing: Its based on internet platform that provides some computing services like hardware, software and other computer-related services.

    Cloud Computing is in three flavors:

    • SAAS(Software as a service)
    • PAAS(Platform as a service)
    • LAAS(infrastructure as a service)

    1.SAAS: it is the topmost flavor of which we develop the application on which application is generally visible to any user. Ex-Gmail, google doc etc.
    2. PAAS-it is the second or central flavor of cloud. its provides runtime platform on demand.
    3.IAAS-its the last or most fundamental layer of cloud. its provides all infrastructure like physical resources, storage,  network devices etc on demand.

    Types of the cloud:
    1.Public clouds-in which services are available to everyone where the resources are allocated as per requested.
    2.Private clouds-in which services are available only those used within the company.generally its protected by the firewall.
    3.Hybrid clouds-its combination of both type of clouds in which organization provides the permission for using services.

    Cloud Testing Forms:
    It can be divided into 4 different categories;
    1.Testing of the whole cloud: in this, we test cloud as a whole entity based on its features, specification, and testing is carried out based on that.
    2.Testing within a cloud: in this, we test that inside the cloud by checking each of its internal features.
    3.Testing across the clouds: this testing is based on specification and based on different type of clouds like a public, private and hybrid.
    4.SaaS testing in a cloud: in this, we test functional and non-functional testing as per requirement.

    Testing types in the cloud:

    • Performance
    • Availability
    • Compliance
    • Security
    • Scalability
    • Multi-tenancy
    • Live upgrade testing
    • Load
    • Functionality
    • Regression
    • Retesting 
    • Network Testing

    Benefits of cloud testing:

    • Low cost
    • Dynamic availability of testing environment
    • scalability
    • Easily customizable

    Cloud testing tools:
    Tools for Performance Testing in the Cloud: this tool is used for performance, load and stress testing and some tools are used for functional testing

    • SOASTA CloudTest
    • LoadStorm
    • CloudTestGo
    • AppPerfect.
    • Jmeter
    • Cloudslueth
    • CloudTestGo
    • AppPerfect

    cloud security testing tools:

    • Nessus
    • Wireshark
    • Nmap
