Why should i use Ruby on Rails?


Previous yesterday(22 Feb, 2014) we had Delhi NCR Ruby Meetup on Open Source Saturday – How can I contribute to Ruby on Rails?. There i had opportunities to meet few college student, Once of them asked to me – Why should i use Ruby on Rails? Yeah, That’s really good question 🙂 So let’s talk, why should we use Ruby on Rails when dozen of language and frameworks are available.

1. Ruby on Rails provides a consistent approach to build your web applications. If you have already experienced with other web development language or framework, you can understand, how tough it was process, you typically need to survey and ask with expert to choose your various software components to solve the common architectural problems of persistence,  build scripts, testing, logging, database setup, application configuration, web tier components and rest of software life cycle. Using the Ruby on Rails framework these decisions are already made for you, now you can spend more time to understanding software business problem and quickly build a working prototype. By using Rails you become productive in minutes not weeks or months.

2. Ruby on Rails follow CONVENTION OVER CONFIGURATION pragmatic philosophy, this apply in all layers of your software development architecture with the highest productivity gains noticeable in the relationship between the model and the database(ORB- Object Relationship Model). Once the developer understands the rules and constraints, Rails MVC magically connects your view to your controller and model, and your model to the database. That’s awesome .!! You do not have to write any script or tool to manage all this ==> MVC – Model View and Controller.

3. When we talk about OOP’s, Ruby is a fully featured object-oriented language and in addition Ruby come with mix-ins modules which contain independent code to inject into your classes and block. Ruby is an extremely dynamic/run time language, which means that code can be generated and executed on the fly. It’s dynamic nature includes the definition of new classes & methods, as well as the overloading of operators etc. Apart from this you can re-open, redefine and removed existing classes on fly.

4. Unlike other web language and framework, rails has build in templating support, json/xml document and email service.

5. Rails comes with ActiveRecord, Association and ActiveModel(object relationship mapping), which provides seamlessly persisted interface to database like transactions, inheritance, validation, scope and caching.

6. Rails includes support for a variety of web technologies like JavaScript libraries, JQuery, REST, Embedded ruby, HAML, CoffeeScript etc. with configuration in development, test and production environments. If you are planing your application into Web 2.0 space, Rails provides a rich abstracted interface to implementing AJAX operations.

7. Most important rails gives us flexibilities to perform database migration and rollbacks between environments and across development until project at mature stage. However with the Rails framework you will be delighted with the implementation of database migrations for applying and rolling back database changes. You only need to enter your update and rollback scripts in Ruby, framework understands the current version & can move forwards or backwards to any database version.

8. Getting started with Rails is easy as generators/migration will propel you along. DRY(Don’t Repeat Yourself) principle of Rails encourage experience developer to write less code by using the metaprogramming features of Ruby. Overall less code to write means higher productivity, less bugs and minimum complexity.

Why do people use App42PaaS when AWS is present?


Recently i came across question: Why do people use App42PaaS when AWS is present?

It’s really interesting 🙂

Firstly, let me tell you, AWS and App42PaaS are different kind of cloud service providers. There should not be any comparison between them as AWS provides IaaS(Infrastructure as a Service) where as App42PaaS provides PaaS(Platform as a Service).

Now you must thinking what are the differences between them. Right?

In very short, IaaS gives you instance of Virtual Machine where you need deploy your application on top of it. PaaS gives you an environment where you just push code with some basic configuration by choosing them.

Let’s talk in details:

AWS:

Now a days, people are used to refer IaaS as HaaS(Hardware as a Service) as name suggest, IaaS provide us hardware, servers and networking components including storage. Once you own the instance, its become your responsibilities for housing, running and maintaining it and you typically pays on a per-use basis.

App42PaaS:

App42PaaS basically help developer to speed the development of app, saving money and most important innovating their applications and business instead of setting up configurations and managing things like servers and databases. Other features buying to use App42PaaS is the application deployment process such as agility, High Availability, Monitoring, Scale / Descale, limited need for expertise, easy deployment, and reduced cost and development time.

Hopefully, i answered above question, if still you have question let me know in the comments.

What is cloud computing? When to use a cloud?


Hi Friends, Sorry i was quite busy from previous couple of months So don’t get time for post. It’s really great experience working on cloud computing, basically on PaaS(Platform as a Service), BaaS(Backend as a Service) and IaaS(Infrastructure as a Service) with ShepHertz. I came across multiple questions, people asking about cloud computing segment. So i thought of write a blog on Cloud Computing.

Let me explain cloud computing segments in details to understand Cloud Computing.

Cloud computing: Cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

Cloud Computing Segment:

IaaS(Infrastructure as a Service) – Infrastructure as a Service is a provision model of cloud computing in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis. Ex- Amazon Web Services, BlueLock, Cloudscaling and Datapipe

PaaS(Platform as a Service) – Platform as a Service is one of the GROWING sector of cloud computing. PaaS basically help developer to speed the development of app, saving money and most important innovating their applications and business instead of setting up configurations and managing things like servers and databases. In one line I can say Platform as a service (PaaS) automates the configuration, deployment and ongoing management of applications in the cloud. Ex: Heroku, EngineYard, App42 PaaS and OpenShift

SaaS(Software as a Service) – Software as a Service, SaaS is a software delivery method that provides access to software and its functions remotely as a Web-based service. Ex: Abiquo’s and Akamai

BaaS(Backed as a Service) – Backend as a service (BaaS), also known as “mobile backend as a service” (MBaaS),is a model for providing web and mobile app developers with a way to link their applications to backend cloud storage while also providing features such as user management, push notifications, and integration with social networking services. Exp: Kinvey, StackMob, App42 API and Parse

Hopefully this post makes it much easier to understand cloud computing. Let me know in the comments if you love it or find any difficulties to understand.
