Azure Virtual Machines (VM) is one of several types of on-demand, scalable computing resources that Azure offers. Typically, you choose a VM when you need more control over the computing environment than the other choices offer. This article gives you information about what you should consider before you create a VM, how you create it, and how you manage it. An Azure VM gives you the flexibility of virtualization without having to buy and maintain the physical hardware that runs it. However, you still need to maintain the VM by performing tasks, such as configuring, patching, and installing the software that runs on it. Azure virtual machines can be used in various ways. Some examples are: Development and test – Azure VMs offer a quick and easy way to create a computer with specific configurations required to code and test an application.  Applications in the cloud – Because demand for your application can fluctuate, it might make economic sense to run it on a VM in Azure...

Disable SELinux. Prior to starting our install, we need to disable SELinux. #setenforce 0  Modify  #vim /etc/selinux/config and change enforcing to disabled. Install Prerequisites. We now need to install the programs that Core will need in order to function / install properly. #yum install httpd php php-cli gcc glibc glibc-common gd gd-devel net-snmp openssl-devel wget unzip -y Now, let's create a user and group for Nagios to use. #useradd nagios #groupadd nagcmd #usermod -a -G nagcmd nagios #usermod -a -G nagcmd apache Download and Install Nagios This is where we will download the required .tar.gz files for Nagios and Nagios Plugins. #cd /tmp #wget https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.1.1.tar.gz wget #http://www.nagios-plugins.org/download/nagios-plugins-2.1.1.tar.gz Now that the files are extracted, let's start compiling Nagios! #./configure --with-command-group=nagcmd #make all #make install #make install-init #...

The Azure Backup service provides simple, secure, and cost-effective solutions to back up your data and recover it from the Microsoft Azure cloud. What can I back up? Why use Azure Backup? The Azure Backup service provides simple, secure, and cost-effective solutions to back up your data and recover it from the Microsoft Azure cloud. On-premises - Back up files, folders, system state using the Microsoft Azure Recovery Services (MARS) agent. Or use the DPM or Azure Backup Server (MABS) agent to protect on-premises VMs (Hyper-V and VMWare) and other on-premises workloads. Azure VMs - Back up entire Windows/Linux VMs (using backup extensions) or back up files, folders, and system state using the MARS agent. Azure Files shares - Back up. Azure File shares to a storage account. SQL Server in Azure VMs - Back up SQL Server databases running on Azure VMs. SAP HANA databases in Azure VMs - Backup SAP HANA databases running on Azure VMs.

Each Region is completely independent. Each Availability Zone is isolated, but the Availability Zones in a Region are connected through low-latency links. A Local Zone is an AWS infrastructure deployment that places select services closer to your end users. A Local Zone is an extension of a Region that is in a different location from your Region. It provides a high-bandwidth backbone to the AWS infrastructure and is ideal for latency-sensitive applications, for example machine learning. The following diagram illustrates the relationship between Regions, Availability Zones, and Local Zones. Regions. Each Amazon EC2 Region is designed to be isolated from the other Amazon EC2 Regions. This achieves the greatest possible fault tolerance and stability. When you view your resources, you see only the resources that are tied to the Region that you specified. This is because Regions are isolated from each other, and we don't automatically replicate resources across Regions. When...

Amazon Elastic Compute Cloud                                                                                                                   What Is Amazon EC2 ? Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) cloud. Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster. You can use Amazon EC2 to launch as many or as few virtual servers as you need, configure security and networking, and manage storage. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, reducing your need to forecast traffic. Features of Amazon EC2. Am...
