Quick and Dirty PHP website hosting using Aws Lambda
The developer of this repository has not created any items for sale yet. Need a bug fixed? Help with integration? A different license? Create a request here:
Host your website on Aws Lambda with full PHP 7 support (i.e. pay by requests instead of paying a fixed monthly hosting fee).
Now it's possible for you to host dynamic PHP files, static HTML files, css files on AWS Lambda (serverless) just like an Apache server running modphp. Any files you put inside the
publicdirectory will be accessible as if they were hosted on an Apache server with `modphp`. There are no handlers to write or config files to maintain.
For example, put two files, index.php and deep/other.php inside your
publicfolder. The type
lambdaphp deploy -v. Once deployed you should be able to access them online at https://yourdomain.com/index.php, https://yourdomain.com/deep/other.php, etc (details below).
The Difference is you don't have to pay any monthly hosting fees because they're running on AWS Lambda which means you are billed only by the number of requests. This includes 1 million free requests per month and 400,000 GB-seconds of compute time per month (details here).
With just a simple command your updates are live instantly.
Aws Lambda can scale from 0 to virtually infinite instances without any extra code or setup. So whether your site gets one hit or a million hits a day it can handle all scenarios easily.
Are you hosting your site on a $500 server yet not fully utilizing all server resources? AWS lambda is billed by number of requests not by monthly usage, so for a site that gets less than a million requests per month it is virtually free forever!
Are you spending a lot of time configuring load balancers, docker containers, etc to handle loads? Now you don't have to since it's all done for you.
Why make a user in India connect to a server thousands of miles away in America? Even if your site is super fast, the download will still be slow because of network latency. Aws Lambda Edge makes it possible for users to connect to the nearest server making the downloads super fast.
Since the lambda instances (or web servers) are created on demand and destroyed after each request, it makes it virtually impossible to hack your web server or install any malware on it.
Same as above. No need to patch or upgrade packages as they are managed by the vendor. Plus the server is read-only an created and destroyed after each request, making it virtually impossible to exploit or install malware on it.
To install, just type this on your command line (terminal)
composer create-project lambdaphp/lambdaphp
This should create a project-name directory inside which there is a
publicdirectory. Any files, including any PHP files you put in the
publicdirectory can be accessed directly from your web browser.
Once you're done putting files in the
publicfolder, just type this on your command line to deploy your site on AWS Lambda:
lambdaphp deploy -v
You may need to enter your AWS credentials as described here (same as aws-cli).
If everything goes as expected, you should see this message:
Website deployed! To access your site visit: https://XXXX.execute-api.us-east-1.amazonaws.com/web/<any-file-in-public-folder><.php>
(If you get a "command not found" error, make sure you have./vendor/binin your PATH)
That's it! LambdaPHP will give you the URL using which you can access your site just like any other site hosted on Apache. It is possible to use your own custom domains with https too (details here).
Using LambdaPHP you can now use AWS Lambda to:
file_put_contents, etc works seamlessly with AWS S3 (using S3 stream wrapping)
Sessionsand works right out of the box! (DynamoDB session wrapper under the hood)
You can also use your own domain to host these demos
In previous version of lambdaphp you had to upload the PHP executable and a bunch of files (min 32MB) every time you made even a small change to any php file. Starting with this version lambdaphp now uses AWS Lamba Layers. It even creates a seperate layer for the
vendordir (inside public directory) to ensure that minimum amount of update is needed to deploy.
By default it uses the PHP layer which I've compiled with PHP 7.3 (with most mods including ImageMagick) but if you want to use a custom LayerARN, just modify your
lambdaphp.ini, create a
[php]section and set the
layerArnvalue to your own Layer's ARN. Read the FAQ for more info.
So anyway, what this means to you is that previously it meant even a small update took 40MB and 5 minutes to deploy, the same can now be done in 1kb under 1 sec! How's that for speed improvements? :)
This is still in beta so bear with me. But here are some remedies:
AdministratorAccessin your IAM (if you're in a hurry). Though it's better to enable the following access instead (requires full access):
Api Gateway(for invoking lambda via http).
Try to clear composer's cache and re-installing it (composer sometimes picks old versions)
Currently it supports PHP 7.3 with most mods including PDO, GD and ImageMagick.
Yes, you get 1 million free requests per month and 400,000 GB-seconds of compute time per month. Currently lambdaphp runs very fast with 128MB RAM and has an average response time is 20 to 50ms. So using the pricing calculator here, you can process about 1,000,000 (1M) requests per month free of cost. YMMV. Also remember every asset on your page creates a new request, so factor that in and bundle them together using Webpack.
The average load time is 25ms (via pingdom). Use Webpack to reduce the number of requests per page (bundle CSS, JS, Font files, etc into a single js file). This will also make sure to reduce the number of requests per load helping you stretch your 1M requests even more.
Theoretically speaking AWS Lambda scales very well so it should be able to handle a lot of traffic easily. It performs better with more traffic since that reduces the load time. But for anything above 1M requests / day, you may consider a dedicated instance instead.
I've currently compiled php using the most popular PHP extensions. If you need to a custom extension, just using the Dockerfile in Robert's project below.
It's a quick and dirty way to get simple PHP website online without paying any monthly hosting fees. Also a great resource if you wish to learn Amazon's amazing services like API Gateway, AWS Lambda, S3, DynamoDB, Cognito (which work together under the hood of lambdaphp) for your own sites.
Open (or create) file
lambdaphp.ini(it should be inside your project's root folder) and create a section called
crontab. To add cron jobs just use the following format
job_name = 'cron(rate_expression)',php_file.php,enabled|disabled
So let's say you want to ping your site every 5 minutes. Here is how your
[crontab] ping = 'cron(*/5 * * * *)',ping.php,enabled
After you run
lambdaphp deploy, this will create a cron job to run
publicdirectory) every 5 minutes!
To remove this cron job, just remove it from your
lambdaphp deployagain (alternatively you can mark last column as
disabledto temporarily suspend a cron job without removing it)
The timing of your cron job is controlled by the rate expressions as described in the link.
It could theoretically at least with some tweaks but I haven't had the time to test it. Maybe if you do, do let me know too!
This was just a weekend project for my own amusement but I will definitely add more features
