AWS Lambda is a serverless computing service that allows developers to run code without provisioning or managing servers. One of the biggest advantages of AWS Lambda is its pay-as-you-go pricing model. You are charged only for the compute time your code actually consumes. When your code is not running, you are not billed, making it a cost-effective solution for many modern applications. Instead of maintaining infrastructure, you simply upload your code. AWS then handles running, scaling, and managing the execution environment. AWS Lambda is well suited for a wide range of application scenarios. Developers can write functions using supported programming languages such as Node.js, Java, Python, Go, and C#. Once deployed, these functions run within the AWS Lambda runtime environment. …

What is PHP-FPM? PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that makes a website capable of handling strenuous loads. By setting specific amounts of resources, it even allows a host to process a domain’s requests. To accomplish this, the PHP-FPM maintains “pools” (workers available to respond to PHP requests) where these “pools” of workers allow the website to handle more requests than it normally could. PHP-FPM is faster than traditional CGI-based methods such as SUPHP for multi-user PHP environments. It does not overload a system’s memory with PHP from Apache processes as ruid2+php-dso does. This method is useful when a user receives extra traffic that requires resources to process it. For example, your website may …
