How to create a custom resource with Kubernetes Operator

While developing projects on the Kubernetes platform I came across an interesting problem. I had quite a few scripts that ran in containers and needed to be triggered only once on every node in my Kubernetes cluster. This could not be solved using default Kubernetes resources such as DaemonSet and Job. So I decided to write my own resource using Kubernetes Operator Framework. How I went about it is the subject of this blog post. When I confronted this problem, my first thought was to use a DaemonSet resource that utilizes initContainers and then starts a dummy busybox container running `tail -f /dev/null` or another command that does nothing.

Network monitoring challenges in heterogeneous environments

The growing complexity of network environments poses great challenges to effective network monitoring. This should come as no surprise: such environments can include bare metals (on-prem solutions), data centers, private and public clouds. Additionally, automation, orchestration and SDNs can greatly enhance your network management, but at the same time add yet another level of complexity. In this blog post, we will discuss the main challenges related to monitoring and how to solve them to streamline the entire monitoring process.

P4-programmable smartNIC controlled by ONOS (video)

The traditional NIC (Network Interface Card) is a relatively simple device equipped with Ethernet interface(s) and used to enable connectivity between machines. SmartNICs, by contrast, offer much more sophisticated capabilities and allow you to perform advanced operations on packets. SmartNICs are thus perfectly suited to optimize network performance in a data center, especially those that are programmable and offer the computing resources required.

SDN vs traditional networks: revolution or evolution?

SDN is definitely a buzzword in the networking world. Software-defined networks are now gaining momentum among enterprises. But is this a truly disruptive technology that is going to replace legacy networks? Or is it a logical step forward in the evolution of the network? In this blog post I will discuss these questions. As I see it in the introduction to SDN, this is an evolutionary step for networks, not a revolution. Considering the benefits SDN technology offers or even starting to adopt it does not mean sweeping aside the traditional network as we know it.

What are the benefits of SD-WAN? In a word, legion

Software-defined WAN is becoming increasingly popular, and for good reason—it effectively solves a number of important challenges posed by traditional WAN architecture. Reduced costs, increased application performance, more flexible network topology, faster deployment and improved security are the main benefits SD-WAN offers. Read on to learn more.A WAN, or Wide Area Network, is the computer network spanning a wide geographical area (regions, countries or even world). You need a WAN when you have a number of geographically distributed local networks that need to communicate with each other.

Edge computing and virtualization — living on the edge

Cloud offers considerable benefits to businesses. Yet in some cases where low latency is critical, it has serious drawbacks. An emerging paradigm of edge computing is the answer to these problems. In 2016, Cisco announced the beginning of the Zettabyte Era. Since then, the amount of data produced and processed has increased zettafold, if you will. This is especially true when you look at M2M applications (machine-to-machine or more commonly referred to as Internet of Things—IoT) such as video surveillance, healthcare monitoring, the smart home, smart meters and the like.

The difference between SDN and NFV — a simple guide

Network Function Virtualization (NFV) and Software Defined Networking (SDN) technologies are similar and can easily be mistaken for one another. Given their growing popularity of late, it is good to know what SDN and NFV stand for, why they are so popular and what business benefits you can expect from them. In 2016, Cisco published the report “The Zettabyte Era: Trends and Analysis” announcing that by the end of 2016 annual global IP traffic would pass a zettabyte. To be mathematically precise, a zettabyte is a measure of storage capacity equal to 1021 (1,000,000,000,000,000,000,000) bytes.

How to create a WordPress custom theme for better site performance

Wordpress is no doubt the most popular blog platform. It’s easy to learn and set up even for people without technical skills. Additionally, you can use plenty of themes both free and premium. However, using premium Wordpress themes may result in decreasing load time and thus hamper your website’s performance. Lower performance means bad user experience and a lower place in SERP rankings. In this blog post, you will find a tutorial on how to create a custom Wordpress theme and improve your website’s performance.
