What is cloud Application Development?

To clarify Cloud computing is a network for data storage and online processing.Also In cloud computing groups of servers work together to perform the tasks.

Cloud application is the smart application which can be accessed from any device and from anywhere due to its advanced technology.

Furthermore With the advancement in business world, the role of cloud Application Development has immensely increased.

Role in big companies

For instance Cloud Application development is used by almost all big companies as it saves money, time and human work force.Most importantly Cloud Application development is user friendly, convenient and manageable. In addition It saves the companies data and information in a well-managed order and easily accessible way.

Furthermore With the advancement in technology the companies try their best to stay up to date with the technology.

Cloud application and its types

stackscale.com

For example In the present times almost all companies use cloud Application Development and with the increasing use of cloud computing various types of cloud application development have been developed these types include

• SaaS
• PaaS
• IaaS

 Software as a service (SaaS)

Firstly SaaS is the most used and most convenient type of cloud application. It does not require any skills and techniques and is ready for the user to be used anytime.

It is accessible from multiple devices.It demands a stable internet connection to work. Google drive is a well-known example of SaaS.

Platform as a service (PaaS)

Secondly PaaS gives the user the ability to run, process, manage and develop the applications it is a bit complex than SaaS as it requires an application code by the developer. Its examples include AWS, Heroku etc.

Infrastructure as a service (IaaS)

Thirdly Out of all the three types IaaS is the least user friendly as it requires the provider’s tools for development. IaaS plays a part in security, backup location and scaling etc. Its examples include Oracle virtual Box, Xen and Hyper V etc.

The development process

The cloud application development can be better understood by the SDLC which is an abbreviation for the software development life cycle.

This life cycle has various stages.These stages give us a better understanding.These stages are listed below:

• Requirement analysis
• Design
• Development
• Testing
• Deployment
• Maintenance

Now we will further explain these steps in terms of cloud application development:

Requirement Analysis:

This is the first stage for the development. This includes the analysis of all the things required.For instance the time and the cost needed.

Design:

Firstly After analysing the basic requirements. We make a design.This includes the prototype of the infrastructure.This would cover the basic elements.

Development:

Secondly the development.If the design covers all important aspects.the design takes the form of an actual program through development.

In this step programmers do the workmost effectively and efficiently. We consider this as the longest stage.Also This step includes the coding of the program.

Testing:

Thirdly After development we pass the program through  a series of testing.Here we  debug it and test it for any faults. This is a very essential stage.In this stage we ensure the best quality development for the program.

Deployment:

Moreover we send the program to Deployment for installation and activation.

Maintenance:

Also in this stage we repair any damage in the program after we sell it to the user.

Technological tools to develop cloud application:

We use Back-end and front-end technologies for cloud application development, in the back-end technologies we have Java, PHP, .NET etc. and in front-end technologies we have react and angular etc.

Back-End Technologies

Now we will explain the back end technologies.

existek.com.                                                                  Java:                                                                               Most programmers use Java language. It is very well known.. Many IT specialists use java all around the world.

The reason why java is suitable for cloud application development is that it saves time, is effective and can run on any device.

Java is also used in mobile and web development. Java is considered expensive otherwise it is ideal for cloud application development.

PHP:

PHP is another amazing choice as it is perfect for start-ups and small or mid-sized projects. It can create software in different domains and variety.

We consider it a great choice.because a specific interpreter processes its code on the web server.

.NET:

Microsoft has developed. NET. It is a hybrid framework as it provides the programmers with the opportunity to use different tools, languages and

libraries for desktop mobile and web development. .NET provides variety of languages and tools and we consider it excellent for cloud application development.

Front end technologies:

React and angular and explained below

React:

Facebook created React. React is a very good choice for cloud application development. Also it saves time and is easily understood.Even the people who never worked with JavaScript can understand this.As it has a JavaScript library for building single page solutions.

Moreover, React is fast simple and very efficient, it uses reusable UI components which make it cost and time effective as it can rebuild the whole application in case of any accident.So it is considered excellent for cloud application development.

Angular:

Another JavaScript framework is angular which is also a great choice for cloud application development.

Angular is more convenient than others because of its JavaScript and convenient component based architecture but it might be a bit complex when it comes to its learning curve.

Benefits of cloud application development:

We can get various benefits from Cloud computing. For instance business, IT, economy and many other fields. Moreover we describe the few important benefits of cloud application development as follows:

Data backups

Companies as well as individuals have important data they don’t want to lose, one major benefit is that cloud

computing can store data on the cloud and in case we lose our data we can still recovery it from the cloud.

Restore data

Also  we can restore Lost data from the cloud.

High speed;

And We get more effective data transfer and storage, with cloud computing we can access our data in seconds.

Cost effective

Furthermore Cloud application development is cost effective as we will not need additional hardware for storage and less human workforce will be required to maintain and manage the cloud.

Saves time

This also provides us access to the latest applications in a few minutes giving us quick results hence saving our time.

Unlimited storage capacity

Also The best thing about cloud computing is that we can have unlimited data storage capacity on it this also saves money and energy as we will not need a new device,a hard disk or a memory card and the energy used in transferring and managing data is saved.

Reliable and effective

Moreover security of data on the cloud makes it more reliable. Also we can manage and easily access our data.

Easy access

Another benefit is that we can access  the data from any device even in remote areas with a stable internet connection.

Cost of cloud application development

digitalplussolutions.com

We cannot estimate the exact cost for cloud computing .but we can calculate the estimate overall cost.

from the factors such as program used, programmers cost, application, experience and location of services.

Different regions offer different costs for programming.For example in the US the quality of development is far better than that in Asia.

however, it might not be affordable so a country which can develop an affordable and a good quality program is selected for outsourcing for instance Ukraine helps in attaining both, an affordable price and a good quality.

A single person cannot do the development of cloud application. A team performs this task.

tasks together to save time and work more efficiently, this team includes the project manager, business analyst, UI/UX designer, server side developer, front end developer, QA specialist.

We can summarise the  salary of all these team members to estimate the cost of cloud application development.

Moreover For a rough estimate if we consider that all the specialists have 4 years’ experience we can have an overall estimate if we consider their salaries as listed below:

• Project manager-$60
• Business analyst-$60
• UI/UX designer-$50
• Backend developer-$70
• Front end developer-$70
• QA Specialist-$40

Keeping in view the experience of the developers, the complexity of the application, the programing tools and the design we have:

Three different types of applications

• A simple web application’s cost will vary from $30k to $100k
• A medium complexity cloud application’s cost will vary from $120k to $250k
• The most complex enterprise application’s cost will vary from $250k and more
