The best way to get started with AWS is to enhance and speed up your WordPress site by using two of Amazon’s web services, S3 and Cloudfront. S3 is a service which allows you to upload files to a remote server that Amazon runs, and then serve them up to users across a distributed network, making download speeds of larger files (like media files) a lot quicker. Cloudfront is an optional extension of S3, and is a fully fledged CDN (Content Distribution Network). A CDN takes your sites static assets, and caches them on servers around the world. When a user downloads that asset from your site, it is pulled from the server that is geographically the closest, and assets are downloaded as quickly as possible.
Pricing for both S3 and Cloudfront is based entirely on use, and costs are kept fairly low. For a medium sized blog with a good amount of traffic, you might spend $2 – $5 / month for both services. However, this will vary based on how many assets your site has, and what kind of traffic it receives. You can use the AWS calculator to estimate your costs. The service itself works by exposing the servers you purchase to an easy to use API, which you can use to programmatically upload and access files. So if you’d like to use S3 and Cloudfront with WordPress, the first step is to set up that API.
Setting Up AWS
The first thing to do is actually create an AWS account. You can do so by visiting the signup page and using your Amazon credentials. You will be automatically signed up for all available services, though you only pay for what you use.
We want to start by creating an S3 bucket where we will store files from our WordPress site. Click on the S3 button in the main Amazon dashboard. This will bring you to the blank S3 console, with an option to “Create a Bucket”. Click this to create your cloud storage space.
You will need to give it a name, using alphanumeric characters and no spaces, that is unique across all users of S3. That means if any other user has already chosen a bucket name, it is off limits for all users. When choosing a name, try and pick something unique to your site, like your domain name.
For now, we are just going to leave our bucket empty and move on to Cloudfront. Cloudfront is not required for some of the solutions we will discuss below, but it can speed things up quite a bit for your users. It will also cost a bit more each month.
To set up Cloundfront, return to the main AWS dashboard and click on the Cloudfront service link. On the next screen, click the “Create Distribution” button. From the next screen, select “Get Started” under the Web option. The next step will ask for an Origin Domain where it should serve files from. Here, you can select the S3 bucket you just created to sync the services up. There are lots of other options here, but most can be left at their default or blank. Finally, click “Create Distribution” to actually start the service.
With everything set up, the last thing you need to do is get access to your API keys. These will allow WordPress services to connect with your AWS cloud without needing to authenticate every time they do. To get your API keys, you will need to create an IAM user that has access to your AWS account. First, go to the IAM console and click on the “Groups” tab.
You will need to create a new group and user to grant access to. Click “Create New Group”, give your group a name, and then select “Administrator Access” in Policy Template step, and create your group. Next, click on the “Users” tab and click “Create New User”. Once again, give your user a name, and make sure the “Generate an access key for each user” box is selected. Once you’ve created the users, you will be provided an access key and secret access key. Make sure to store these somewhere, or click “Download Credentials” to download them to your computer. The last step is to connect your user with your Group by click on the user that you just created and selecting the “Add User to Groups” option, and selecting the group you created in the first step. This will ensure that the access keys associated with this user have access to your account.
Amazon S3 and Cloudfront Plugin
If you are not looking for a full-featured caching plugin, and would simply like to offload static assets to AWS, you can use the Amazon S3 and Cloudfront plugin, which should be downloaded on top of the Amazon Web Services plugin. The latter will connect your WordPress site to AWS, and the former will store your media files in the cloud. The plugin is limited to just media files from the media library, but these are the heaviest files on your site, and therefore most suited for a CDN.
To set the plugin up, you will need your Access Key and Secret Access Key to your site’s wp-config.php file. Open up wp-config.php for your site, and add in these two lines:12define( 'AWS_ACCESS_KEY_ID', '*****************' );define( 'AWS_SECRET_ACCESS_KEY', '*************************************' );
Make sure to replace the stars with your created user’s access key and secret access key.
Once you’ve added these keys and saved your settings, you can customize the plugins functionality in AWS -> S3 and Cloudfront. On this screen, you can customize which S3 bucket you want to use for your media files, and optionally add support for Cloudfront distribution. The plugin will work just fine without this, but it will speed things up considerably for you if you chose to use it.
There are also a few more settings for the plugin, such as whether or not to store files locally and in the cloud, and whether or not to serve files over SSL. You will need to check off these boxes in order for the plugin to begin working with the cloud. Once everything is set up, future files will be uploaded and served to users according to your settings. At the moment, the plugin does not support uploading existing files to AWS. The plugin keeps things fairly simple, makes set-up easy and does most of the work for you behind the scenes.
