So, if we talk about cloud computing, it is the delivery of computing services that includes database, networks, storage, software, and analytics.
Types of Cloud Computing:-
1. SaaS
2. Paas
3. IaaS
Cloud computing works by enabling users access to add data on any selected device.

Hi, I am developing a C# based desktop application which has GUI developed using WPF.
My application has some SQLite database where I save users data.
1) Now I want to place this database in the Cloud so that if user lost it in local device, it can be fetched from cloud from anywhere.
2) Every time whenever local database changed it should be synchronized with data which is there in Cloud. i.e., there should be bidirectional synchronization.
Now I have two options. One is Windows Azure and other is Microsoft Sync Framework.
Please tell me which one I can go for now?
Though Windows Azure is not free, I can go for it. But is it useful?
Since my application is C#/WPF desktop application, can I go with Azure?
Any help please?
Thanks

Hi there .. Im new to Cloud computing but I have developed much apps in C#. I want to develop a SaaS application in Java, plz tell me what I need to learn in java except its basics which I have learnt. Should I call SaaS a web application? do i have to learn JavaScript to develop SaaS ?.
Is that essential to use a PaaS or IaaS provided by google, amazon and Microsoft? I just learned that there is a library or Framework named "CloudSim" Which can be used to create your own cloud on a server by using cloud architecture and by a VM. I dont know how to use them, and is this is good to have your own cloud than using others infrastructure ?

Hello, thanks for providing a detailed question which many members don't bother to do.
However, your question is more towards the basics and I would recommend you start by reading about cloud computing and virtualization. Just start with some free videos on youtube and read some blogs. There are plenty of them out there.
In your case you would most likely go with an PaaS or IaaS by the mentioned vendors unless your company has a data center of its own - which means a private cloud.
In theory, a SaaS application isn't something magical compared to a general app that you would build. Just that it is hosted on a cloud (yes on a VM mostly) and is being marketed to multiple customers.
Whether to have your own cloud or use MS, Amazon, Rackspace - it depends on how much money you want to spend vs how much money you can make.

We are running payroll application in web forms .
Now we are in the stage to move to SAAS model and to use azure.
Searched in internet but could not find proper information to start.
Is azure support multitenant by itself or we need to create in web application?
We plan to create separate database for each tenent.
Please Advice.

I am not 100% sure what you mean by this, but I suggest you get a bit more familiar with Azure, as it's not only Web sites.
In fact, I don't see why you could not just port what you already have to Azure, THEN see if you want to switch to an SAAS model.

Azure is a platform that supports building and running multitenant applications. Architecting the right kind of azure data storage strategy is the key in getting your application run in multitenant mode on Azure.
To answer your question, Azure platform supports applications that can run in multitenant applications.

if your current payroll application is running as single tenant application then you have to build the necessary support in your system to support multi tenancy such as how you want to isolate the date between the tenants in storage level and how authentication should be handled for different tenants and customization's you want to provide in your app e.g separate site logo for each tenant like that there are many things to consider during the design. There is no direct way to convert the single tenant app to multi tenant system.
Have a nice day

I've got an ASP.NET Web Pages site that draws fractals, it uses a SQL Compact database and works fine locally.
But now I want to publish it to the Azure Cloud and I get an error in the Database.cshtml that it doesn't work.
Is it true that SQL Compact doesn't work in the Azure Cloud?
The URL is: http://aljo-fractals.azurewebsites.net
Error: Failed to find or load the registered .Net Framework Data Provider.
I use WebMatrix 3
I guess I need to add the framework to use the database, where do I get that?
This must be easy to fix, but how...

.NET CF is for PDAs and Embedded devices.
Use the regular Desktop frameworks.

Do I need to use NuGet? What is the exact name of the framework I need?
The point is, it works fine locally in Webmatrix.
Does it have to do with a connectionstring in de configuration file?

SQL Compact cannot be used in Windows Azure.
You need Windows Azure SQL Database for this.
|
|
|
|

That was the general response I originally gave you.
So you got things fixed then?

I read this just now, I would have reacted immediately otherwise.
Compact SQL works just fine on Azure. You just need to deploy the proper DLLs. I have a site (test) working fine with it.
Now, another question would be, beside "working", to ask if SQl Compact is "adapted" to Azure, and the answer would be NO!
Simply because, beside working, you need to be able to follow easily the main feature of Azure, which is scaling (up or down) by creating instances of your site. Compact being purely local, you would end up having as many DBs as Instances, which is not great.....

can someone give me a compact equation which i can use to project a 3-d object on to a 2-d plane? For example if i have a cube, how can i calculate the x,y co-ordinates of the 6 vertices on a 2-d plane when its rotated 360 degree, moved towards or away from the projection plane, etc. I want to use this formula to code a c# application. Please help me!

Just wondering if anyone uses IaaS (I guess Amazon EC2 would be the frontrunner) or maybe even PaaS?
What are the key things you look for in terms of services in either of the two? Perhaps region, price, or the services available?
|
|
|
|

From IaaS/PaaS perspective, you should look at the
1) Range of available Options : Is the infrastructure providing faster computing resources OR storage OR database services OR a combination of many.
2) Pricing : Fixed Pricing or Pay as you Go. Later being the best.
3) The current trend of incoming and outgoing traffic of the provider: Most chosen by customers or not.
4) SLA : On the situation of an outage, what is their policy? Refund ? History of outages ?
5) Scaling systems in place : Are load balancers installed by the providers which keep the service instances always up.
