Now we can click “Launch Instances”.Īll good. From the drop-down menu we choose “Proceed without a key pair”, and check the box below. Check that the “AMI details” are correct and then click “Launch”.īefore launching the instance, we are asked to select a key pair. We click on “Review and Launch” and we land on this page. Thus, before launching the instance, we need to go on the tab 6 (“Configure Security Group”), and select “HTTP” from the drop-down menu. To access to Rstudio in the cloud with our browser we need to configure the security in the right way. The “Free Tier” instance is already selected, so we do not have to do anything. Now we landed on the AWS page of the AMI we choose. Here is the Wikipedia page about AMI (Amazon Machine Image) if you want to know more, but you do not need to. Go to this webpage and choose one of the AMI on the right of the page, according to the geographic location (in my case: EU West, London). Ideally, we would like to run it on a (virtual) computer with RStudio installed.
Now we want to run our script in the Amazon cloud. (In any case, Amazon probably already knows our credit card number.) (2) Launch the AMI
It asks us some personal data, including the address and, annoyingly, a credit card number, in case we use products that are not free, or exceed the usage limits. Let’s go to the AWS webpage and create the account. However, some products - including the one we will use - are free. Amazon Web Service “provides on-demand cloud computing platforms to individuals, companies, and governments, on a metered pay-as-you-go basis”. So, follow this short instructions, and you can close your laptop and have your script running for you somewhere else! Step-by-step tutorial (1) Create an AWS accountįirst of all, we need an AWS account. If you do not trust me, most material comes from here, but it is not explained step-by-step, some information are possibly not relevant for a non-expert (as myself) and, mostly, the AWS interface has been changed from when the page was written. However, I just found out that launching your RStudio script on Amazon Web Service ( AWS) is quite easy (and it is free).Īs the information needed is scattered on the web, I put together a short tutorial. Sometimes - as it happens to me now, running this individual-based model - you do not have this option. If you are lucky, you may have access to a cluster, or a remote computer, where you can run your script. Here a situation that may have occurred to some of you: your R script (a model analysing a big dataset, a simulation where you test many parameter combinations) needs hours to run.
