Hi Developers,
Let me introduce my self here, i am new to this cloud community. I am thinking to developing a small Application in cloud, which is related to Bookmarks and it is completely Freeware, can some one please let me know, where i have to start and what Libraries i have to use in C#.Net and how to get the free space in Cloud..
Being a Freelancer, just want to give some utilities as freeware as my passion. Please some one help me with the following
1. How to get free cloud space
2. Libraries for the same in C#
3. Get started with some samples and implement them with visual studio...
Thanks in Advance...

Hi folks,
I have been developing desktop applications in C# for two years. But, after I read some about cloud computing, I was very interested in pursuing my career so that I can develop apps on the cloud. Currently I am studying my Masters in Computer Science. I have also done two web apps(one in PHP and the other in JSF).. I don't have that much experience in web development.
Do you think it is possible for me to get a job so that I can develop on the cloud without having an experience in web development? Or do you recommend me to develop we apps(get a job in web development) for 2-3 years and then start working on the cloud? Please give me your personal opinion.
Thank you

That's essentially the same thing... web apps are working on the cloud (unless its a download/ run locally type of thing).
I'd recommend you get as much experience in whatever it is you want to do before trying to find a job in that field. Most people will not want to hire someone with absolutely no experience. If you need some suggestions for projects, maybe look to the open source community and try to help where you can.

I agree - and brush up research, find reasons to code in JavaScript. Then look into libraries like jQuery and such. AND of course, HTML5 - as that will bring a lot of functionality to cloud computing.

I don't really think that you need experience in web application to start working in cloud. Your 2 years experience in windows application can give you a real kick start. All you have to do is get some personal trainings and hands on experience in cloud computing.

To be honest, I dont think that is true because, I have learned web application 3 months before and now I am starting to develop apps on the cloud and if I haven't had a web knowledge, it will be very difficult to work on cloud computing. You need to have at least the basics.
Any ways, thank you for your suggestion.

Dear all,
This is my first message to the forum.
I'm a beginner to developing cloud computing apps. I have a small
question please. I understood that in order to develop a Cloud
Computing application, I need to develop it using PaaS (like Google
app engine, Amazon web services or Microsoft Azure) and I knew that
there are some open source frameworks like Hadoop or Eucalyptus, that
could help me develop a parallel application that would run easily on
the cloud. My question is, is what I understood correct? Is there any
other way to developing Cloud applications?
I'd be grateful if you could help me.
Thanks and best regards,
Nermine Naguib

Four days and you still haven't tried this[^]?

Of course Richard the first thing I've done even before sending this question was googling it! but I only could find the methods I mentioned in my message, I just wanted to make sure that I understood them correctly and that I didn't miss anything else because I'm required to make a report about all the alternative techniques of cloud applications development. I have no one to ask... I know no one with experience in cloud computing and I was waiting for a more professional reply from people with more experience in this field. Thanks anyway... although honestly I didn't like the way you replied to me.

I think perhaps you misunderstand what the CodeProject is about. You posted a question asking for information about tools and techniques for Cloud computing. After four days with no response you posted a follow up. The lack of response means one thing: nobody on the site has the information you are looking for so you need to go and do some research for yourself. I'm sorry you don't like the answer, but everybody who gives advice here does so in their own time and at no cost to the people who ask the questions. You could always try a professional Cloud consultant, you will get a better answer but it will not be free (or even cheap).

I'd like to thank you for your reply and apologize for misinterpreting your first message...
I love CodeProject since I was in the first year at college and maybe that's why I was very happy to find the cloud computing forum and sent my question here in the first place 
thanks again for trying to help!

Well not necessarily, you could code your own framework from the ground up (  ).
Jk, find a system that you feel comfortable with and work with it. Google's framework and Microsoft's Azure platform are good starts. I think the latest Linux based cloud frameworks are still immature for commercial use.
Actually, in all honesty, if you take away the bells and whistles you could build your own framework. The abstraction of the propagation of resources between platforms into a "cloud" is easy enough to code. I'd recommend sticking with a tried and tested system for business and work related development, but the aforementioned could be a fun code project.

Iam very new to the cloud computing concepts.....may i know how it is used and why ?
|
|
|
|
|
Cloud Computing is an architectural concept that will drive us into 70's VT-100 terminals but with an HTTP client built-in 
It's the concept of software exposed as service over the internet, only that.
|
|
|
|
|
It's amazing that with new technology, the theme is always the same (dumb terminals vs. web browsers, client server vs web services, etc). I wonder what new technology will be for the punch card.

OK, this is by no ways a very informed answer and it's not particularly my field... but during the Customer Test Program phase of Microsoft Azure coming into being I created an account and had a play. During that time I could immediately see some obvious applications, and recently when I was looking at actual enterprises that have gone with Azure some were very much along the lines of what had gone through my mind. By the way, why Azure and not some other solution would almost certainly have to do with whether ones's business was already aligned to MS technologies, such as .NET development. Writing apps for Azure is not significantly different to writing any other .NET applications.
One application for example was an event ticketing site (if that is the right term.. ticketing of sports events, concerts etc).
That specific application has certain aspects that might suggest the cloud as a very cost-effective solution. It is likely idle for much of the time, but could have extreme demands at others... thousands of people trying to snap up concert tickets in a few minutes. To maintain one's own infrastructure to support this application would not be trivial! And it's definitely not something that you plop onto a typical web-hosting site, it would break in a minute flat. But the underlying Azure platform takes care of the scaling of that workload (e.g. creating new VM instances for large volumes of workflows), and the cost is basically "pay for what you use". Your infrastructure cost is, crudely speaking, proportionate to use (and we presume that during that use you are making money).
Without getting into it, I was also intrigued by the service bus component of Azure. Again, pretty crude playing, but it seemed relatively easy to host aplications on my machine that were exposing WCF service endpoints on the worldwide web (Azure) to other networks. I could immediately think of some possibilities for "out of the box" apps communicating with other business entities.. perhaps exchanging EDI documents as an example. Of course there would be other ways of doing that, but I could see some definite uses for Azure to (I think) greatly simplify some things. Remember, I am a .NET developer so Azure made sense to me. I doubt that what they offer is really unique, it is MS particular cloud solution.
This is just one example, and I have not really defined "what is the cloud?" to which you will get a million different answers. Whether an application is suited to cloud hosting gets down to a lot of factors and would require a great deal of analysis and cost analysis.
And like you, I have really only investigated this stuff a bit... you would probably get a thousand conflicting opinions and many of them by more informed people. But I think platforms such as Azure definitely have their place.

I have my own feelings on the Cloud computing movement, but I have to earnestly research it as a fiscally pleasing alternative to a hardware purchase needed for a large database solution I am developing. Amazon's AWS is the suggested service.
After researching the pricing of the service, it appears that it may quickly become costly for a server that must remain up 24/7/365 and is constantly updated in batches of 10-100k rows per second. The kicker is that this database server is for internal use only so if we hosted it in our network, it would not increase our in/outbound bandwidth, however if hosted in the cloud, it would, and we would also get charged for this from AWS's side.
According to their site, storage costs are:
Amazon EBS Volumes
• $0.10 per GB-month of provisioned storage
• $0.10 per 1 million I/O requests
While data transfers are:
Data Transfer In US EU Regions APAC Region
All Data Transfer $0.10 per GB $0.10 per GB
Data Transfer Out US EU Regions APAC Region
First 1 GB per Month $0.00 per GB $0.00 per GB
Up to 10 TB per Month $0.15 per GB $0.19 per GB
Next 40 TB per Month $0.11 per GB $0.15 per GB
Next 100 TB per Month $0.09 per GB $0.13 per GB
Over 150 TB per Month $0.08 per GB $0.12 per GB
Also, I won't be able to accurately estimate volume usage, IO's or data transfers until the system were to go into production. However, it can't go into production until I have chosen a hardware solution. The cloud's pricing system is making it more difficult because I could end up racking up huge bills once it goes prod.
My question is: Is it possible to make the decision to go with a cloud service for a new system? Or is it only viable for systems where X, Y and Z are known? And if this is the case, why not just stay with the current physical hardware?

Following are the 10 special reason to use cloud
1: Familiarity of Windows
Azure is based on Windows, so you can write applications in the same programming languages you’ve used for Windows apps: Visual Basic, C++, C#, etc. You can also use familiar tools such as Visual Studio, along with ASP.NET and other familiar Windows technologies. This makes it easy for organizations to find developers who already have the skills to create applications for the Azure platform. And because the Azure environment is much like the standard Windows environment, it’s easier to create a cloud version of an existing Windows application.
2: 64-bit Windows VMs
Applications running on Azure run in virtual machines, with each instance of the app running in its own VM on the 64-bit Windows Server 2008 operating system. The hypervisor on which they run is designed specifically for the cloud. You don’t have to supply your own VMs or deal with managing and maintaining the OS because apps are developed using Web role instances or worker role instances that run in their own VMs. The apps interoperate with other Azure components through a Windows Azure agent that runs in each VM. With Azure, you can focus on the code and don’t have to worry about the hardware.
3: Azure SDK
Microsoft provides the Windows Azure software development kit (SDK), which includes a version of the Azure environment you can run on your own computer. It’s called the Windows Azure Development Fabric, and it includes the Azure agent and storage. You can work locally when developing and debugging an application and then move it to the cloud. You can download the tools for Vista Studio 2008 and 2010, along with the SDK, from Microsoft.
4: Scalability and flexibility
Using Azure, you can easily create applications that run reliably and scale from 10 to 10 thousand or even 10 million users — without any additional coding. Azure Storage provides scalable, secure, performance-efficient storage services in the cloud.
After you create a Web app, you can specify the number of processors for the application to use. If the application needs to scale up to meet growing demand, it’s easy to change the settings to use more processors. The “pay as you go/pay as you grow” approach lets you bring your new apps to market sooner and respond more quickly to changes in your customers’ needs.
5: Cost benefits and pricing model
Taking advantage of resources in the cloud allows you to decrease your costs for building and expanding your on-premises resources. You can also reduce the cost of IT administration because the hardware is being taken care of for you, off-premises. The cost of creating, testing, debugging, and distributing Web-based applications goes down because you have to pay only for the computer processing time and storage space you need at a given time.
Windows Azure pricing will be based on consumption, with a per-hour fee that’s dependent on the size of the instance for Azure computing services and per-month or per-transaction fees for Azure storage services based on data size. For pricing details, see the Microsoft Web site.
6: Data center in the cloud
SQL Azure provides organizations with all the benefits of an enterprise-class data center without the hassle, headaches, and cost of maintaining such an entity. You get high availability and reliability with redundant copies of your data and automatic failover. No more worries about backing up data yourself.
It’s a relational database model that stores data in the same manner as SQL Server (tables, indexes, views) and thus will be familiar to Windows DBAs, but your SQL Azure Server is spread across multiple physical computers for more flexibility. For information about the differences between SQL Azure and SQL Server, see Similarities and Differences - SQL Azure vs. SQL Server.
7: Support resources
Because Azure uses the same familiar tools and technologies as other Windows platforms, you can take advantage of the well-established support structure within Microsoft and company-provided resources, such as TechNet and MSDN, along with the huge ecosystem of Windows developers outside the company. There will always be someone to turn to when you have questions or problems.
8: Interoperability
With Azure, you can develop hybrid applications that allow your on-premises applications to use cloud services, such as the cloud database and storage services. Communications services work between on-premises applications and the cloud, as well as mobile devices.
Azure supports open standards and Internet protocols, such as HTTP, XML, SOAP, and REST. There are SDKs for Java, PHP, and Ruby, for applications written in those languages, and Azure tools for Eclipse.
9: Security
Knowing that security is one of the biggest concerns for companies considering a move to the cloud, Microsoft designed Azure with security in mind. The .NET Access Control Service provides a way to integrate identities, and Security Assertion Markup Language (SAML) tokens are used by applications to determine whether a user is allowed access. Microsoft has designed its compliance framework to meet regulatory requirements. For more details, see my article Microsoft Azure: Security in the Cloud.
10: Something for everyone
Windows Azure can benefit hosting providers, ISVs, systems integrators, and custom software developers. Hosting providers can expand their services to areas where they don’t have existing infrastructure and add new services without more infrastructure investment. ISVs can use Azure to create, deploy, and manage Web apps and SaaS without large capital expenditures, and they can scale those applications more quickly and cost effectively. Systems integrators can take advantage of Azure’s ability to work with existing on-premise infrastructures. Custom software developers can create software solutions for customers who can’t afford the costs of in-house development, including hardware costs, and they can deliver their applications to customers as services without building and maintaining an expensive data center.

I'm having real difficulty figuring out whether this is the next big thing or the next big flash in the pan. I'm also unclear on the (nebulous you might say...) concept, papers on the subject don't really carify it for me.
My questions are specifically:
- Software as Service: How is this really different from a well designed SOA archtecture over, say, WCF, other than where the code runs
- Who owns the code?
- Who writes the code?
- Where does your code reside and how do you test it? How "transportable" is the code?
- Are you locked into a vendor? If so, the dangers this raises surely outweigh than any efficiency gains you might find.
- How are security concerns addressed?
- Is this really different than outsourcing a company's hardware function (other than the frameworks involved?)

I don't think it is.
You do.
You do.
On Microsoft Servers as I understand it. Published I believe via VS2010.
yes. Microsoft.
Not very well last time I read about it. They're addressing it, but it still needs work.
I don't think it is. The idea is that Microsoft takes care of all that stuff for you. You buy the level of service you need and the number of instances you want. It gets very contractual. Think their licensing agreements.
I've stayed away from it for the time being because I can't see any sizable company wanting to allow Microsoft to have control and hostage taking power over their data and livelihood. It sounds like a real downer.

Thanks for the reply, after one week, an answer! This isn't meant as a criticism of you, it just screams volumes about the amount of work going on in the cloud I think.
People keep screaming "next big thing" on the cloud, but when I look at it, the security concerns and the "ransom effect" will prevent business such as banks (who tend to be the drivers on such things) from ever using it. I hadn't considered Miscrosoft's Byzantine pricing structure, even for something as "simple" as VS2010 we had to get an external consultancy in to find the best deal for our company.Their cloud pricing must be horrific. Some people are really fired up about this, and I've been wrong about technologies in the past (Windows devs are resisting WPF, which I think far superior to traditional Winforms), but I think this is a dud, at least in the medium term. My post was really a last-gasp should I take a look at this tech, or should I do something else question.
Cloud Computing might have a use for SMEs though: the security provided will probably be better than can be acheived in-house,but I suspect Google is a better option.
