Which programming language for cloud computing

Question

Now that the new cloud computing-era is coming  and I am going to learn to program  I don t know which programming language the clouds support   I think what the support Java  ASP NET  PHP  Python  Ruby  Perl etc  and not the low-end languages  like C  C   etc    Or am I wrong  If that is so software companies will have to re-develop their software  Is this the time you can start a project  and you have no big software company as a competitor   I want to know which language I should focus on learning  so that I can develop for the cloud

As for what programming languages  any browser-based or server-based language is likely to be used  Javascript  PHP  ASP  AJAX  Perl  Java  SQL   Let s say you need to implement a new programming language and BCL designed specifically for operating in the cloud  it won t be used on client machines ever   It should be optimized for cloud computing  easy to learn  fast  efficient  powerful  modern   The biggest way i   ve seen cloud hosting products help out developers is the ability to launch and increase the size of a server  without having any kind of delay  Developers are able to create the application in a completely customized environment  and then expand it into a production machine with a significant hassle  If things don   t work as wanted  they can then destroy that machine with relative ease   Most of the Cloud Computing Providers used JAVA and C-Sharp  to make cloud server

Obviously there is no  better  -- or more worth learning -- language at all  Which language you use is is just a matter of what you like AND what your server supports  You should not learn a language that wouldn t be supported by any server or is said to be dying in the near future  On the other hand it is obvious too that there will be even better languages in the future and that those will be more useful  So learn one that is fast  convenient and that you like and where learning it wouldn t be a too big effort because  as said  you re likely to change in less than 3 years   I  personally would be considering an  open-source   not proprietary  one  because the web is open to everyone and open-source is more likely to be supported by every-one   Which means PHP in this case

This is always fascinating   I am not a cloud developer  but based on my research there is nothing significantly different than what many of us have been doing off and on for decades   The server is platform specific   If you want to write platform agnostic code for your server that is fine  but unnecessary based on whoever your cloud server provider is   I think the biggest difference I ve seen so far is the concept of providing a large set of services for the front end client to process   the front end  I m assuming is predominantly web or web app development   As most browsers can handle LAMP vs Microsoft stack well enough  then you are still back to whatever your flavor of the month is   The only difference I truly am seeing from what I did 20 years ago in a highly distributed network environment are higher level protocol  HTTP vs  TCP UDP    Maybe I am wrong and would welcome the education  but then again I ve been doing this a long time and still have not seen anything I would consider revolutionary or significantly different  though languages like Java  C   Python  Ruby  etc are significantly simpler to program in which is a mixed bag as the bar is lowered for those are are not familiar with writing optimized code   PAAS and SAAS to me seem to be some of the keys in the new technology  but been doing some of this to off and on for 20 years

Depends on which  cloud  you would want to use  If it is Google App Engine  you can use Java or Python  Groovy too is supported on Google App Engine which runs on jvm  If you are going with Amazon  you can pretty much install any OS  Amazon Machine Images  you would like with any application server and use any language depending on the application servers support for the language  But doing something like that would mean a lot of technical understanding of scalability concepts  Some of the services might be provided off the shelf like DB services  storage etc  I heard about ruby and Heroku  another cloud application platform   But dont have experience with it   Personally I prefer Java Groovy for such things because of the vast libraries and tools available

That is a very interesting question   On the Lang Next conference there was a very interesting discussion about this topic  in which authors of several programming languages participate  Scala  Dart  C    There was not a clear consensus at the end  but from my point of view there is one message   The ideal language for this  cloud age  should be object oriented  because that is how we understand and are able to model the world  and also embrace functional programming    The code in  cloud age  is almost always distributed  running on several cores machines  in the cloud center  or just the client server separation  And it is also asynchronous  We do not block the code when waiting for WS response  The callbacks come in any time   When using standard imperative programming languages  handling the asynchrony and the distribution really complicated  You have to always take care of the  current state  and when the callbacks come in  you have to decide what to do  in dependences of this state   Functional programming helps to eliminate the  state  and is much better suited for this new situation   So I would say  In cloud computing the code is distributed  state-less  asynchronous  Functional programming can help you with that  Object oriented is almost a must to be able to model the world   I have wrote a blog post about it  if you are interested  I like C   but actually I would say Scala  Clojure  F  might fit even better   On the other hand C   will always be there  and lately is being modernized and getting more attention

Your question is a bit vague about what you are actually thinking about doing   Cloud computing  can mean almost anything  If you re looking for languages with specific cloud computing advantages  Java has several because it s a compiled language that compiles to operating-system independent byte code   I also chime in with the others about C   being a low-level language  Yes  it is  But you re always going to have more than just the C   language  If you separate both Java and C   from the classes that come with them  Java and C   are extremely similar  You have to adopt some rigid criterion like  pointers   low-level  garbage collection   high-level  to make the distinction stick   And  of course  you can make pointers smart and invisible in C   and you can use garbage collection in C   too if you want to

Cloud computing  is more of an operating-system-level concept than a language concept   Let s say you want to host an application on Amazon s EC2 cloud computing service -- you can develop it in any language you like  on any operating system supported by EC2  several flavors of Linux  Solaris  and Windows   then install and run it  in the cloud  on one or more virtual machines  much as you would do on a dedicated physical server

Of the languages you mention Java  PHP  Python  Ruby  Perl are certainly more platform independent than C C    and ASP NET     Lots of platform-specific differences also come from what libraries are available for a given platform   In practice however  I think you will always develop on the same or at least very similar platform  operating system flavour  as the system where your code will run  i e  the cloud will not take source code and compile it for you before running it   Personally I would go for Java or Python  probably also Ruby  as they have a vast number of libraries available for all kinds of tasks and are very platform independent
