Time and money are two of the most valuable resources for entrepreneurs building the next big product in today’s fast-changing technology landscape. Choosing the right cloud platform plays a critical role in saving both. One common dilemma businesses face is whether to choose a lower-cost server option or invest in a more scalable and efficient cloud platform. While cheaper solutions may reduce upfront costs, they can slow down development and impact long-term performance. This makes the decision between platforms like AWS and OpenStack more complex. Pricing Considerations Public cloud platforms like AWS are optimized for short-term and dynamic workloads. They are ideal for environments where demand fluctuates, allowing businesses to scale resources up or down as needed. However, for long-term …
After the dot com bubble and information technology explosion, data and information are available and accessible around the globe. Making your website live is like unlocking the door to your premises with your office and safe open. Things are just the same, except that you will never see anyone come to your website unless you have protection systems in place. Data thieves are invisible and fast, searching for your website for details of your customers’ account data, especially for their e-payment information. You have a legal obligation to protect this data from theft and to report if security breaches occur, particularly when dealing with cloud security and compliance requirements Stealing your data or information is not the only thing …
Cloud computing has transformed how businesses deploy and manage infrastructure. Instead of maintaining physical servers, organizations now rely on scalable cloud platforms that can dynamically allocate resources as demand changes. One of the most powerful open-source solutions enabling this transformation is OpenStack. What is OpenStack? OpenStack is an open-source cloud computing platform used to build and manage public and private clouds. It primarily delivers Infrastructure-as-a-Service (IaaS) capabilities, allowing organizations to: With OpenStack, administrators can spin up or shut down instances on demand, making it ideal for environments that require flexibility, automation, and scalability. Brief History of OpenStack OpenStack was launched in 2010 as a joint initiative between Rackspace Hosting and NASA. The project is now governed by the OpenStack Foundation …
Did you know? Digital Realty Trust uses more renewable energy than any other data center provider, followed by Equinix, according to the US Environmental Protection Agency’s new data. Companies that use providers like Digital and Equinix are increasingly interested in data center services powered by renewable energy, partly because of their own corporate sustainability programs and partly because energy generated by sources like wind and solar has gotten a lot cheaper in recent years. In response, the providers have been sourcing more renewables to address the demand.
In today’s digital world, messaging applications have become an essential part of everyday communication. Millions of people use platforms like WhatsApp, Messenger, Skype, Telegram, and Snapchat to share personal conversations, photos, business information, and sensitive data. But the important question remains: Are Your Private Messages Safe Online? Many users assume their conversations are completely private. While modern messaging services offer various security features, the reality is that online communications still face risks from cybercriminals, data leaks, and surveillance activities. This blog explores how private messaging works, the risks involved, and how users can better protect their online conversations. The Growing Importance of Message Privacy Messaging platforms are no longer used only for casual chats. Today they are widely used for: …
A serious vulnerability named Dirty COW has been discovered recently which has put the Linux kernel under risk. It is said that this vulnerability was noticed nine years ago (since version 2.6.22 in 2007) and remained unnoticed throughout this time. A researcher named Phil Oester was the man behind the detection of this serious threat. According to him, the vulnerability is described as a race condition where the Linux kernel’s memory subsystem handles the copy-on-write (COW) breakage of private read-only memory mappings. In this way, the attackers gain write access to read-only memory updates and this paves the way to their increased privileges on the system.
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. However, if the server is running cPanel / WHM you must edit the configuration file through the GUI as cPanel / WHM will revert your changes automatically over time.
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 of PAM and is now deprecated. We can create or add new PAM modules at any time and the programs can immediately use these newly created module and password method …
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 customer can use more than the limits set for that customer. Today we can limit CPU, Memory (virtual and physical), IO, number of processes as well as the number of …
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 in server. Setup Need to have two CentOS systems : NFS Server NFS Client Server yum install nfs-utils nfs-utils-lib chkconfig –levels 235 nfs on service nfs start Here we are …
