With the digital transformation, the volume of data is and the number of devices used is increasing. This trend will continue with more and more IoT applications. This requires new possibilities in orchestrating and managing networks - which will not work without automation. Software-Defined Networking (SDN) promises the solution at this point. As a Software-Defined Data Center has already proven … [Read more...]
Is Virtualization a Prerequisite for the Cloud?
Virtualization is repeatedly in this website mentioned as the basic technology for cloud computing, but it is not a prerequisite for cloud computing. Distributing hardware resources to virtual machines is one of several possible strategies to achieve multi-tenancy. With software as a service, in particular, large players show that virtualization is not a prerequisite for the provision of cloud … [Read more...]
Why JVM is Called Virtual Machine?
The virtual machine part inside the phrase "Java Virtual Machine" often confuses many peoples with full virtualization. A Java Virtual Machine is an example of application virtualization. The Java Virtual Machine converts the compiled Java code into machine language to run it on the host computer. At that time, there was a concept named WORA (Write Once Run Anywhere). Today, we still have the idea … [Read more...]
Key Points to Plan Virtualization and Cloud Migration Migration Rightly

Technologies such as IoT, edge computing, blockchain, machine learning or software-defined data centers also characterize the current IT change. We explain the basics and what you have to consider in Cloud Migration, Virtualization etc. According to IDC and Gartner, cloud computing is the primary option for digital … [Read more...]
What is Virtual Tape Library?
Tape drive is the only storage media of choice for an economically-valid archive strategy. In order to understand what is virtual tape library, we need to understand the original physical tape drives and tape libraries. Tape Library is a storage device containing one or more tape drives, slots to hold tape cartridges, and barcode reader to identify the tape cartridges. Tape drive is a data storage … [Read more...]
What is Hyper-converged Infrastructure (HCI)?
It is common to find what is Hyper-converged Infrastructure (HCI) in plain English. Hyper-converged Infrastructure is software-centric architecture which is based on the processors, memory, network virtualization and other closely interrelated technologies. Standard hardware with commercial off-the-shelf (COTS) components can be used as hardware. Often, such hyperconvergent systems are offered and … [Read more...]

Here is the Second Part of Virtualization Requirements for DevOps. In this article, will give brief idea about the benefits of virtualization such as efficiency and reducing costs, … [Read more...]
Virtualization Requirements for DevOps : Part 1
This article mainly refers to the technical side of the DevOps idea. However, if one wants to implement them in own company, the employees must be trained accordingly. In addition, DevOps is more likely to target larger projects where a lot of coordination is needed. In order to be able to react quickly and flexibly to new business requirements, development and operations must work together better … [Read more...]
Mainframe Server Virtualization : Basics
Mainframe, UNIX and real physical terminal mean real powerful computing. Mainframe server virtualization avoids maintaining many racks of servers with cables adds scalability, savings in long term in green way. The reason mainstream server businesses can not run mainframe as servers is partially initial higher cost of purchase and partially due to lack of knowledge. 5-6 years ago from today we … [Read more...]
Container Virtualization Growing With Challenges
In older articles we talked about container virtualization and quite related application - OpenVZ virtualization. In general, when we talk about container, we mean Docker. We can actually run Docker on OpenVZ which is called nested virtualization. The containers seem to guarantee improvements in the application development. Distribution of applications faster reduces the deployment effort. More … [Read more...]
