Docker overview: Docker is an open source project to pack, ship and run any application as a lightweight container. The idea is to provide a comprehensive abstraction layer that allows developers to containerize or package any application and have it run on any infrastructure.  Docker leverages LXC (Linux Containers), which encompasses Linux features like cgroups and namespaces for strong process isolation and resource control.  Terminologies: IP: An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication Virtual IP: A virtual IP address (VIP or VIPA) is an IP address that doesn't correspond to an actual physical network interface (port). Uses for VIPs include Network Address Translation (especially, One-to-many NAT), fault-tolerance, and mobility. Bridge: A bridge device filters traffic at a network boundary....

I will start by giving a short introduction about hyper-converged infrastructure. It is a virtual computing infrastructure solution that integrates discrete data center services in a product’s form factor, which accelerates its speed and agility of deploying virtualized workloads. It also reduces the complexity, improves operational efficiency, and lowers the overall operational costs.  This feature rich, infrastructure provides a powerful virtual server environment that can be set up often in an hour or less, and is simple to operate and scale. The overall hyper-converged market is based on a model known as Open Storage Platform (OSP).This was initially developed by large Web companies to store and manage their enormous amounts of data, generated by their social media and Internet-based channels.  There are some key drivers for the Hyper-converged infrastructure market but I feel these are the ones which impact the most: Legacy Infrastructure cost – Enterpri...

There is one simple question to ask, to determine whether business needs a backup and disaster recovery plan: “Can business continue to function with any critical data, applications and operations being lost?” Yes is the only answer that would indicate that it does not need a feasible and reliable disaster recovery plan. Let’s face it, any system has its data at risk. There could be a machine error, a virus, a human error, or even a natural disaster, which could just ruin systems data. Not having the proper backup plan in place could mean losing all your critical data. Because data is the heart of the enterprise, it's very crucial to protect it. And to protect organization's data, there is need to implement a data backup and recovery plan. One practical example for this situation is "The VMware App Volume BCDR Manager" . VMware's App Volume is an application delivery system through which applications are delivered to virtual environment like virtual deskto...
