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 …

How to Enable and Customize PHP-FPM Directives/Pool for a Domain or Server Wide :: cPanel
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 …
HAProxy stands for High Availability Proxy. It is a very fast and reliable solution for high availability and load balancing. HAProxy is used as TCP/HTTP Load Balancer and for proxy Solutions. The HAProxy application will share the workload with multiple servers. Steps for Installation and Configuring HAProxy =========== Step 1: Before proceeding with the installation of HAProxy in the server, we need to install the epel repository on our system depending on the operating system version using the following command.
In today’s digital world, change is inevitable. The technology and processes that are currently working for your business aren’t guaranteed to work for you in the future. Because of this, it is imperative that you are always planning ahead.
OpenStack is a set of software tools for building and managing cloud computing platforms for public and private clouds. Mostly deployed as an infrastructure-as-a-service (IaaS). Deploy virtual machines and other instances that handle different tasks for managing a cloud environment on the fly. It makes horizontal scaling easy, which means that tasks that benefit from running concurrently can easily serve more or fewer users on the fly by just spinning up more instances. So we can say OpenStack is the future of cloud computing. OpenStack began in 2010 as a …
A “Smart Host” (also known as a relay host) is a type of mail relay server which allows an SMTP server to route e-mail to an intermediate mail server rather than directly to the recipient’s server. This improves the performance of your server and the reliability of your e-mail delivery. Exim Server (Forwarding Server) This server will be forwarding all emails to the SmartHost for relay for final delivery. If you are not using cPanel / WHM, then you will simply edit ‘/etc/exim.conf’ instead of using cPanel / WHM’s interface. …
Pluggable Authentication Module (PAM) handle the authentication tasks of applications/services on the Linux system. In other words, it allows us to configure how applications use authentication to verify the identity of a user. In this article, we are mainly dealing with the configuration file format. The PAM configuration files are located under the directory /etc/pam.d/ which describes the authentication procedure for an application. Each file in this directory has the same name as the application for which the module provides authentication. /etc/pam.conf was the configuration file used in earlier versions …
CloudLinux is one of the widely used Operating System nowadays due to the high-level stability and advanced server security it provides, which makes it the first preference for hosting providers, especially in a shared hosting environment. LVE (Lightweight Virtual Environment) is a kernel-level technology developed by the CloudLinux team. It is lightweight and transparent. The goal of LVE is to make sure that no single website can bring down your web server. The kernel makes sure that all LVEs get a fair share of the server’s resources, and that no …
The Network File System (NFS) was originally developed by SUN Micro-systems that allows communications between Linux/Unix systems. It allows you to mount your local file systems over a network and remote hosts or clients to interact with them as they are mounted locally on the same system. Benefits >> Central Data Management. >> Allows local access to remote files transparently. >> Very good for local or reliable connections Important NFS configuration file /etc/exports : All files and directories which need to be exported are defined in this which is located …
