Cloud Computing

Go to https://www.apponfly.com/en/[^] it works pretty well!

Thank you for your reply.It's usefull to me.

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

There won't be much different in deployment perspective. But you will get additional cloud benefits such as auto scaling of resources , no maintenance worries, basic fail overs and so on.. Not sure what kind of specific information you are looking for, could you be specific. Have a nice day

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.

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.

And what is your question? Use the best guess

ok, strange and unexpected. :omg: interesting... :thumbsup: :-D

the idea with cloud computing is to have all of your application and your files on the internet (the cloud). This way you have some advantages: -it should be less expensive since you don't pay for maintenance of your own server, you only pay for what you need when you need it (you can choose how much resource you want to pay and you can scale it up easily) -you can have your application and files everywhere you go, on whatever device you find (since it's all on the internet you don't need to download anything or at least anything big and can get in from any computer) -you're granted with a really high up time and high security The are disadvantages: -You have to be connected to the internet -you don't have any control over security

Well you can try a Google search for open source projects that offer solutions to your problem, or you can write some code. Though I do not see what this has to do with Cloud Computing. One of these days I'm going to think of a really clever signature.

You should never need to create a new database based on new users resgistering. I suugest that you look at your databade design. However if you really need to do this you will probably have to script it on the database server. What type of database are you talking about here? mySQL, SQLServer ...? You could for example get your code to write a dynamically generated script file to the server and then run it to create your required database. Kind Regards Julian Mummery
