Remarkable developments in the IT sector have created a vibrant business environment worldwide. Improvement in fields like virtualization and consolidation has promoted the IT growth rate to a level that is unprecedented. However, to make the most of these favorable IT advancements, human advancement is vital to create a win-win situation both for consumers and producers. Cloud computing can be quite effective in terms of achieving this common goal, through reduction of complexity in the IT mechanism. If applied properly, it can create a shared environment and can help any business organization, small or large, save time and space.
Advantages of Cloud Computing in Business
‘Cloud computing is a better way to run a business’ – This is how SalesForce.com, one of the most notable cloud service providers, described the emerging IT trend. It may sound like a slimy sales pitch to you if you don’t consider the ‘Say No to Software’ symbol in the website of SalesForce.
In short, cloud computing is a chance for businesses to operate applications through a shared information center. It gives organizations an edge over the ones that use conventional software development methods, such as Oracle and Microsoft, which have too many processes like installations, testing and failovers. Cloud computing, on the other hand, is fast and effective. Here are some of the major benefits of cloud computing.
- It doesn’t require any software or hardware (other than access to a browser) It follows a simple process, facilitating faster integration with different business solutions It’s allows quick operations and reduces chances of failovers It creates a flexible IT environment, where solutions can be customized as per specific requirements of any business with ease It helps in obtaining maximum utilization of resources
With all these advantages, cloud computing is steadily becoming accepted among organizations around the world. In fact, some businesses are limiting their IT infrastructure in order to keep in tune with the settings of Cloud computing, as reported by SalesForce.com.
The Lean-Agile Approach
Lean and Agile are two major production techniques, used widely in businesses. The Lean approach originated from the production methodology of Toyota, post World War II. It’s a biological process stressing mainly on:
- Producing only what is required Removing irrelevant things that does not contribute value Discontinuing production when something is wrong
The Agile approach has contributed exponentially to the developments in the software industry. In this process, software is built in parts and is tested individually before proceeding further. The purpose of using this method is to build an immediate feedback loop between the creators and the users. However, use of the Lean method has become more extensive than the Agile method after 2008. As a result, a new trend that combines both the methodologies emerged. The need for this amalgamation rose primarily due to certain drawbacks in the Agile methods. The Agile method skips any discussion regarding the process of organizing stability of software between different wings of the business. The Lean process can be quite useful in terms of dealing with this. It breaks down development tasks into smaller streams, so that the output of one stream can create the next value stream. Therefore, this combination enables to create a more process-oriented approach to software development; thus, yielding better results.
The Waterfall Approach
The Waterfall Approach has been quite effective for developing software since 1970, when it was first introduced. The method is combination of various steps. The first stage is, understanding the requirements of the customer. To achieve success in this stage, it is important to communicate with clients. The next stage is to design and implement ideas. This is followed by an evaluation process. The phenomenal success of the Waterfall method has been due to the following benefits it has to offer:
- Potential changes can be easily recognized Development can be facilitated even in a large team The budget can be easily chalked out, as the process defines stages clearly Time and energy is saved due to the linear approach
Because of its impeccable track record, the Waterfall method has been able to outdo other methodologies of its time, including the incremental and spiral approaches. However, there are some pitfalls to the method as well. The effect of these drawbacks can go all the way to hamper the growth of the software industry. Its name itself is symbolic of its biggest shortcoming. Much like when the water crosses the edge it cannot retreat, similarly if a fault has been overlooked in a stage, it cannot be corrected.
Agile in Cloud Computing Environment
There is a lot of similarity in the approaches of Agile and cloud services towards application development. The Cloud approach is well known for delivering end-to-end services in application development. Likewise, the Agile method focuses on the requirements of end users. In order to achieve this goal, the Agile method breaks down the task in small parts. This facilitates detail orientation. Planning, developing and testing of each segment is done individually, which helps to remove bottlenecks in the process and maintain high quality standards. Moreover, the Agile process focuses on building a two-way beneficial environment for developers and end users. This creates ample scope to obtain and implement feedbacks as well as make the required changes at every stage.
A highly interactive environment can be created for developers as well as users by integrating Agile and Cloud. Once the developers start utilizing the cloud service, the users are instantly able to review it and give feedbacks on the process. Therefore, stages like patch installations and distributions can be eradicated, which eventually helps in saving time and energy of the organization. One of the leaders in IT consulting and technology outsourcing services, Capgemini, conducted a survey in 2010 in order to measure industry trends regarding incorporation of Agile process in cloud computing.
This study which was conducted by CapGemini in collaboration with HP on around 30,000 quality assurance managers, cloud experts, engineers, and IT managers, employed across leading firms in Asia, North America, and Europe. According to study, as much as 60% of the organizations that participated in the survey are likely to incorporate Agile methods as a part of operations for upcoming cloud projects and services. Some key advantages of integrating Agile with cloud computing are:
- Improvement in the quality of application Maximum utilization of available resources Lower time to market More cost effective
Jonathan Rende, the Vice President and General Manager, Business Technology Optimization Applications, Software and Solutions, HP says ‘IT providers are facing intense pressure to develop new applications that provide competitive edge, bring greater efficiency and generate measurable results.’
Agile and Cloud Computing Integration: The Best of Both Worlds
Cloud computing has become a buzzword in the software industry. The immense benefits of the cloud technology have even forced Microsoft to invest heavily in enterprise cloud solutions. However, combining cloud computing with the Agile methodology can be even more rewarding, helping make the best of both worlds. If you hire a cloud computing expert for your business, it is necessary to enquire about their know-how of the Agile process as well. Knowledge on Agile is very essential to achieve the optimal results with application development.
As noted by the founder and CEO of Cyrus Innovation (an Agile consultation company), Bruce Eckfeldt, ‘The greatest strength of Agile methodology is that it is self-adaptive’. This is why having someone on board who is experienced with both cloud and Agile methodologies can be a great boon for any business. The cloud technology is experiencing a dynamic paradigm shift, and the cloud technology is gradually becoming more demand-focused.
It is time for application developers in the barcoding, mobility and point-of-sale space to adopt these new approaches to application development if they intend to remain relevant in the future.
