Kubernetes Networking Internals

Kubernetes works on the principle of assigning IP addresses to pods, called as “IP-per-pod” model. The IPAM (IP address management) task is left to third party solutions. Some of these solutions include Docker networking, Flannel, IPvlan, contive, OpenVswitch, GCE and others. The Kubernetes architecture consists of master node, replication controller..

Future of Networking : Software Defined Networking (SDN)

There have been a lot of innovations in the virtualization domain which has benefited compute and storage. However those benefits are constrained due to limitations in the traditional network model. It is becoming increasingly difficult task to manage infrastructure which needs rapid network provisioning and also can be a time consuming.

Docker Container – A Silver Bullet for IT Industry

You might have heard word ‘Docker’ much frequently. All the noise is happening IT industries because most of the companies are adopting Docker technology at a noteworthy rate. So what actually Docker is? In a simple sentence, “Docker is an open source, container technology“. Using this technology you can easily create, deploy and run your Linux application

Getting Started with Network Function Virtualization (NFV)

First question that comes to mind is whether SDN and NFV are same or different or related technologies? SDN and NFV are independent technologies. SDN creates a separate management plane which sits a floor above the traditional control plane so as to get wider view of the network and orchestrate using network protocols like OpenFlow. So, with the SDN approach

Securing Docker Containers

Docker is a great technology which simplifies the development and deployment of distributed applications. While building dockerized applications, security at various points needs to be considered. Due to lack of CPU/Hypervisor, Docker security is fully implemented in Software. Let us look at all prominent security aspects of kernel and container applications

Software-Defined Networking (SDN) in 2017

2017 looks to be a promising year for software-defined networking (SDN) enthusiasts. According to recent research by IDC, the worldwide SDN market is expected to grow to $12.5 billion by 2020. This includes physical network infrastructure, control software, SDN applications, and last but not least professional services. Software-defined networking gained

An Introduction to Docker Technology

Containers are tools that run multiple applications on a single host. Docker is one such open source tool which runs on Linux. Docker technology is very similar to Virtualization, except the fact that containers are more efficient and cost effective while virtualizing the operating system because they run multiple workloads on a single host. Docker
