My boss wants me to test our web application to demonstrate how much traffic the web site can handle.
The app is a JSF/JPA/Oracle application, everything is running on one rack mounted server at a local hosting company's data centre.
The truth is, we don't know how much traffic it can handle before it gets unresponsive or shuts down altogether.
What would be a good way to pound on the web app from the internet, simulating tonnes of traffic? I was thinking of setting up a number of different Amazon EC2 virtual machines and getting them to pretend to be web visitors, but is there some kind of software I can run on these machines so they behave like lots of web visitors?
Also, it doesn't have to be free, I'd be willing to apy for a solution or a tool.
Any suggestions or help is greatly appreciated!
Thanks, Rob
Try this, mate:

Did you try setting up Selenium-Grid to run tests in parallel. This will simulate actual user actions on the application and in-turn can stress the app server. You can install a performance monitoring utility on the server to monitor the load generated.
Or you could also use J Meter to simulate multiple users accessing your application. You can talk to your network admin team to route this traffic via internet instead of your local internet.

I'm new to web development and just built my first website with .Net Core. It's primarily HTML, CSS, and JavaScript with a little C# for a contact form.
Without recommending any service providers (question will be taken down), how do I go about deploying the website? The more details the better as I have no idea what I'm doing haha.
Edit: I am definitely going to go with a service provider, however the business I am building the website for doesn't have a large budget so I want to find the best provider at the lowest cost.
Daniel,
As you suspect, this is a bit of a loaded question as there are so many approaches. One approach is to use App Services within Microsoft Azure. You can create a free trial Azure account to start that includes a 200.00 credit, which is more than enough to do all of this for free. Then, using the Azure Management Portal, create an App Service (also free) on an App Service Plan in a region that makes sense for you (i.e. US West). Once you do that, you can download what is called a Publish Profile from within the App Service's Management Portal in Azure.
If you're using Visual Studio, for example, you can then right click your project and "Publish" it (deploy to the cloud, or the App Service you just created). One option in that process is to import an Azure Publish Profile, which you can do with the one you just downloaded. This makes it really simple. The Publish Profile is really just connection information to your Azure App Service (open it in Notepad to see). It will chug for a bit and then publish and load the app for you. You can also get to the hosted version of your app by clicking the Url of the app in the App Service management portal on the main page.
This may be oversimplifying what you need to do, but this is a valid direction to take. AWS and others have similar approaches.
Again, tons of ways to do this, but this is a free approach. :-) I don't consider Azure a Service Provider in the sense that you asked us not to. Instead, I wanted to outline one turn-key approach with specific details on how to get there.
You can find specific steps in a lot of places, such as this link:
https://www.geeksforgeeks.org/deploying-your-web-app-using-azure-app-service/
DanielG's answer is useful, but you mentioned you don't want use any services from service provider.
Usually, there are only three ways to deploy the program,
first one is the app service provided by the service provider mentioned by DanielG,
**Benefits of using service provider products:**
1. Very friendly to newbies, follow the documentation to deploy the application in a few minutes.
2. It offers a very stable, scalable service that monitors the health of our website.
3. We can get their technical support.
**Shortcoming**
It is a paid service, and although Azure's service has a free quota, it will run out.
**Suggestion**
It is recommended that websites that are officially launched use the services of service providers.
second one is to use fixed IP for access (it seems that fixed iPv4 IP is not provided in network operations),
**Benefits of using fixed IP:**
If there is a fixed IP address, or if the carrier supports iPv6, we can deploy our website, and the public network can access it. And if you have domain, it also can support https.
**Shortcoming**
1. There are cybersecurity risks and are vulnerable to attack.
2. Without perfect website health monitoring, all problems need to be checked by yourself, and it is very troublesome to achieve elastic expansion.
**Suggestion**
It is generally not recommended because there is no fixed IP under normal circumstances. Broadband operators used to offer it, but now it doesn't.
If you are interested, you can try ipv6 to test.
the last one is to use tools such as ngrok or frp for intranet penetration.
**Benefits of using intranet penetration:**
Free intranet penetration services such as ngrok, the URL generated by each run is not fixed, and there are some limitations, such as a new URL will be generated after a certain period of time, which is enough for testing.
Of course you can purchase the service of this tool, which provides fixed URLs and supports https.
**Shortcoming (same as the second one)**
**Suggestion**
The functional implementation is the same as the second suggestion, and the physical devices used by the website are all their own. The intranet penetration tool (ngrok, or frp) solves the problem of not having a fixed IP, providing a URL that you can access.
There are few users and the demand for web services is not high, so it is recommended that individual users or small business users use ngrok and frp in this scenario. Generally suitable for OA use in small businesses.
I am trying to build a middleware application ( you know...retrive data from a webservice and store to db in cPAnel and send the data to the webservice hosted from here)
Is it possible to run an application in cPanel?
If it is possible what is the prefferedlanguage for this purpose and
why?
If I am trying to run an application which has to update this fetch
hourly automatically form code.is it possible.means i want this
application to be in running state for an indefinite time.Is it
possible?
My thoughts are:
1. cPanel is not a jumping off point for applications. It is simply a shared hosting management console. It gives you the ability to do some management. You can fire off applications by making a cronjob.
Generally you have two choices, you can use shell scripting or PHP invoked from a shell.
Now this narrows it down further. PHP is configured to have a maximum execution time to stop people hogging the processors.
If you are going to write some proper middleware, I'd suggest that you either get yourself an Amazon, Jelastic or some other cloud hosting provider. You will get the ability to deploy a real application, on a full operating system - rather than "hacking" a solution.
cPanel based installs are really for those people who just want to put a website, whack up a blog, or do some low bandwidth hosting. Running something constantly is going to have you violate the terms of service on these accounts very quickly.
I wrote a small application which needs access to Google API with OAuth2 and which is typically run on maybe a Raspberry Pie to reduce power consumption since it needs to run pretty much 24/7. The device my application runs on is typically connected a LAN at home.
The user controls the application using a web interface from a PC/Tablet/... in the same network. However the web application is reachable from the LAN only, it cannot (and should not for security reasons) be accessed over the Internet, because it hides behind a NAT and/or a firewall.
The documentation states that I have the following options:
Web server applications
This forces me to use a redirect URL which must be known in advance. Since my app is most likely accessed by a dynamic private IP address, there is no way I know the URL in advance.
Installed applications
Yes, that would work. I just need people to copy and paste the returned code into a web form of mine. However that is somewhat uncool.
Client-side (JavaScript) applications
This does not give me a refresh token which I totally need.
Applications on limited-input devices
Polling? Well... If it works... However it requires the user to match a code shown on the device with a code displayed in the webbrowser. If I use that I can just as well ask the user to copy&paste the code returned by the installed app mode.
As far as I can see the copy&paste the code with installed app is my best chance. Is it really? Or is there is possibility to get along without that bit?
I'm looking for a platform with Web UI access that allows me to do the following:
Maintain a list of computers and add / remove based on their IP address.
Provide the SSH information for each computer machine.
Monitor if the machines are up ( ping ? )
Restart the machines with a web UI using the ssh information on the backend of the application.
I'm close to start making such an app myself since I can't seem to find anything close to that in the internet. Any clues if such an application exists ?
You might want to take a look at MeshCentral: https://meshcentral.com/ - you can add systems that you are managing and do some remote operations.
http://info.meshcentral.com/: Meshcentral is open source and is both a peer-to-peer technology with a wide array of uses and web service that is targeted for remote monitoring and management of computers and devices. Users can manage all their devices from a single web site, no matter the location of the computers or if they are behind routers or proxies.
If you are looking for source code you could take a look at the "Open Manageabilty Developer's Toolkit" http://opentools.homeip.net/open-manageability. This tool was built for managing systems with Intel Active Management Technology, but it does a lot of what you are looking for. You can download the source and see if you can use any of it if you decide to write your own UI.
I am ready to deploy my rails 3 site to a server. Who would be the best provider to go with? I need it to be easy to deploy and low cost. Does anyone have any experiences they can share?
http://railsplayground.com is cheapest, they are charging $5/month
heroku.com is free for subdomain hosting ie., http://example.heroku.com
the above two are only for testing purpose if your are going live deployment then
either choose AmazonEc2 or rackspace.com/cloud/

I did it with my first 2 applictions, they have low cost service and online 24 hours support, they send by mail all the credentials to acces your vps or whatever service you have. But if you are new at deploying they can offer to place the app for you, you just send the app by ticket to them and they'll do it.
I have a VPS at railsplayground now, and I pay about 35usd/month, but I have 2 apps on this server and I can have more.. as much as the server can take it, when it reaches the limit, you can upgrade it.
http://www.heroku.com/ is much easier to use, but if you have an app that do uploads on server, heroku will not do it. they store only application.
I am pleased with railsplayground for now.
