 Cloud The “cloud” in cloud computing can be defined as the set of hardware, networks, storage, services, and interfaces that combine to deliver aspects of computing as a service. Cloud services include the delivery of software, infrastructure, and storage over the Internet. A cloud service is any service made available to users on demand via the Internet from a cloud computing provider's servers as opposed to being provided from a company's own premises servers explained before, the most common cloud service is that one offers data storage disks and virtual servers, i.e. infrastructure. Examples of Infrastructure-as-a-Service (IaaS) companies are Amazon, Rackspace, and Flexi scale. Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet).  Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct...

What is software quality assurance? What are the various quality concepts of SQA? Explain.

Image
Software Quality Assurance    - Software Quality Assurance (SQA) is simply a way to assure quality in the software. It is the set of activities that ensure processes, procedures as well as standards are suitable for the project and implemented correctly.  - Software quality assurance (SQA) is a planned and systematic plan of all actions necessary to provide adequate confidence that an item or product conforms to establish technical requirements. - Software Quality Assurance works parallel to the development of software. It focuses on improving the process of development of software so that problems can be prevented before they become major issues.  - Software Quality Assurance is a kind of Umbrella activity that is applied throughout the software process. Software Quality Assurance has: - A quality management approach - Effective Software engineering technology (methods and tools) - Formal technical reviews that are tested throughout the software process - A multitie...

What is Software Requirement Specification Specification(SPS) ? Mention the characteristics and principle of SRS.

Image
Software Requirement Specification - The production of requirements stage of the software development process is Software Requirements Specifications (SRS) (also called a requirements document). This report lays a foundation for software engineering activities and is constructed when entire requirements are elicited and analyzed. - SRS is a formal report, which acts as a representation of software that enables the customers to review whether it (SRS) is according to their requirements. Also, it comprises user requirements for a system as well as detailed specifications of the system requirements. - The SRS is a specification for a specific software product, program, or set of applications that perform particular functions in a specific environment. It serves several goals depending on who is writing it.   -  First, the SRS could be written by the client of a system. Second, the SRS could be written by a developer of the system. The two methods create entire...

What are the major task of requirement engineering? Explain.

Image
Requirement Engineering - The process of collecting the software requirement from the client and then understanding, evaluating, and documenting it is called requirement engineering. - Requirement engineering constructs a bridge for design and construction. # Requirement engineering consists of seven different tasks as follows: 1 . Inception - Inception is a task where the requirement engineering asks a set of questions to establish a software process. - In this task, it understands the problem and evaluates the proper solution. - It collaborates with the relationship between the customer and the developer. - The developer and customer decide the overall scope and the nature of the question. 2. Elicitation - Elicitation means to find the requirements from anybody. - The requirements are difficult because the following problems occur in elicitation. ° Problem of scope : The customer gives unnecessary technical detail rather than clarity of the overall system objective. ° Problem of und...
