CHAPTER-I 1.Introduction 1.1 What is agile Methodology? Agile Methodology is a kind of Project Management Process which predicts the changes and allows much more flexibility than traditional method. Clients can make small changes which doesn’t modify their budgets and schedules. 1. This group of software development methodologies based on iterative development. 2. There is collaboration between self-organizing cross functional teams which evolve requirement and solutions. 3. The iteration time is 1-4 weeks, instead of single pass development process so development process is adjustable with changing business needs. 4. It promotes adaptive planning, evolutionary development, early delivery and continuous improvement and encourages rapid …show more content…
Cloud computing focuses on satisfying user requirements and providing all the necessary applications whenever they are needed. Agile helps in discovering user’s requirements and necessity detection. This also reduces the size of the project by breaking it into small modules which are achievable. This helps in getting users feedback at all levels. These small modules are planned and tested at every level independently so that they can ac The mixture of both agile development with cloud computing provides us highly collaborative as well as interactive environment. To eliminate the lengthy feedback cycles as soon as developers finalize a feature they put it as cloud services so users can analysis instantly and give feedback . this also reduce the probability of misstated and misunderstood requirements hieve high standards. There are so many iterations one for each component and develop a mutual relationship between the developers and end users. At each level we get feedback as the process is completely transparent to …show more content…
It collects instantaneous feedback and make quick changes based on that feedback. The inherent benefit of cloud computing, the rapid development cycle are impossible to implement in traditional development model due to huge cost of distribution. Customer’s feedback is very important because todays idea may drive tomorrow’s functionality. Therefore team only supports only present release and the next release not the legacy releases of years. So many user access the code in a day so if there is any change then everyone come to know immediately. So there is no time waste in merge and integration process. 5.BENEFITS TO COMPANY BY CLOUD Cloud computing is beneficial for business as it provide much more flexibility. It allows you to to connect your business anytime, anywhere with ease to access to data. The main benefits of cloud computing are: 1. Reduced IT cost cloud computing reduces the cost of managing and maintaining the IT system. If we are using cloud computing we don’t need to buy all the expensive system and equipment’s we can use all the equipment’s provided by the cloud service
Flexibility: The basis of agile is to accommodate change as software related projects are constantly changing. If there were a change in market or the emergence of a new product, the product could be easily updated. It also enables new ideas and innovation to be implemented mid-project even after the scope has been defined.
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.
When comparing and contrasting waterfall and agile, they both use the same type of building blocks for the project: scope, cost, schedule and performance. They both also analyze, design, build, test, and deploy the requirement needed for the end result. The difference in these terms for each method is that when using waterfall for scope, cost, schedule, and performance, it sets the scope up front and then allows the cost, schedule, and performance to change depending on what is needed. An agile method will set the cost, schedule, and performance upfront and then have the scope vary, depending on what the company’s requests are after a working prototype. The waterfall is an iterative method meaning the next step cannot begin until the current one is completed. Once the current step is completed, it cannot be revised in anyway unless the project is scrapped and begin again. If the waterfall method is chosen, then the project team
Agile Project management is one of the industries dominating methodology for project management in IT. It is an incremental and iterative way to manage the build and design activities for constructing an IT product, services, and project development in manner which is highly interactive and flexible. In this methodology, scope is defined in granularity that is appropriate with time horizon and checked with the agreement on each feature with the customer. In this methodology work steps are divided with feature breakdown structures. In order to track the progress of the project progress charts are used instead of Gantt charts. Cross-functional and test-driven development teams starts working from the very beginning of the project to provide quality assurance and quality control till the completion. Process of finding and removing bugs is done through iterations and then present to the customer. With the help of Agile approach teams can easily address the core risks of the project throughout the course of development (Thummadi, 2012).
This paper also discusses problems in other Software Development Approaches, How Agile Discovered and why Agile Development Approach is best or why we use Agile Development Approach
1. Once a step has been completed, developers can’t go back to a previous stage and make changes.
...Implementation of cloud systems can be implemented in stages with costs that coincide with usage. The ROI outweighs the issues or problems that could occur. Cloud computing gives a competitive advantage of being able to keep up with changes in technology without having the cost involved. Amazons cloud computing allowed companies like Ericsson to remain competitive and thrive.
Most of the software development projects change just during the development is in process. This is the reason that agile methodology is best for these projects. There is a room for change in them. Software developers follow these methods and this is the reason that they have further modified these methods according to the different types of projects they confront in their development time.
Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.
Agile Development came about as a possible solution to the disadvantages of the Waterfall Model. It borrows heavily from the Iterative Model along with the customer –centric and team-centric approaches to software development frameworks. Instead of handling all the planning upfront, Agile focuses on being lean (reducing waste) and producing minimum viable products (MVPs) over set periods of time.
Cloud computing is able to increase the speed of business. Cloud computing offers the speed to make computing resources on an instance basis, not just need to first survey time and skilled resources in design and implement infrastructure and applications to deploy and test it. Cloud computing can engance revenue, share bigger market, or other advantages.
Agile life cycle contains mainly six phases in its development i.e. Pre project planning (first cycle), Start,
Imagine trying to develop banking software and you have representatives of cashiers, back office operators, finance, human resources, data processing, vault management, online banking and reconciliation all making their individual demands for improvements and corrections throughout the entire process cycle there will be
