Kubernetes is an open-source platform that is portable and extensible, designed to managed cointainerized applications. There are two ways to deploy the container platform, on-premises and public cloud infrastructure. Deploying Kubernetes on premise is often a primary choice but it doesn’t apply in all situations.
But first, a short overview of Kubernetes.
In this article, you will learn about the origins of the popular open-source project and why it matters.
Kubernetes can be likened to a cluster or datacenter OS that manages an entire cluster’s resources. It doesn’t matter whether the nodes are in the cloud or on-premise, Kubernetes takes care of the underlying details so developers don’t have to worry about them.
That is, they only need to develop an app for Kubernetes and not have to think about whether the right amount of resources are located or where the app will run.
What are the differences between deploying Kubernetes on Premise and in the cloud?
On-premises environments need to be repurposed so that they will integrate well with Kubernetes. In some cases, you not only need to create clusters on top of virtual machines but create a new infrastructure as well.
This also means you’ll be able to plan for the right networking and storage equipment to ensure automated networking and storage components.
Implementation in public cloud environments is less complicated as deployment tools of Kubernetes can natively integrate with them. This makes configuration of networking and storage services easy for day-to-day operations.
Public cloud deployments are not applicable to all instance types, however.
The best course of action is a hybrid implementation of both on-premises and public cloud deployment.
More about deploying Kubernetes on Premise via kublr
What are the objectives of deploying Kubernetes cluster on-premise?
- To configure kubectl
- To deploy for demo purposes a simple master (single) and worker node (single) cluster.
- To use Helm to deploy WordPress to a cluster
What are the system requirements for deployment?
- x86 64-bit hardware
- 100Mbs stable internet connection
- Root access to each node
- Supported OS on nodes: RHEL 7.2+ or Ubuntu 16.04 LTS
- Nodes are connected in your network and Kublr Demo/Installer configured IP is accessible from these nodes (ping)
- From these nodes, traffic to Kublr Demo/Installer on ports 9080 / 9443 should be allowed by firewall rules

Multimedia gadget brands such as Lumantek, Angelbird, and Boxcast have been relentlessly polishing their product lines. The reason is that creatives’ needs are continuously evolving—and so do their roadblocks.
As a creative, you might be facing different hurdles such as bad clients or creative blocks. While those are inevitable, you can rely on your armor—your gadgets.
The roadblocks that the right gadget can overcome
1. Lack of confidence
Creativity is the ability to create despite having limited resources; however, if you’re a beginner, it’s hard not to want a crutch. This is typical. Besides, who wants to feel limited by their gadget?
For instance, if you need to stream the live event on a giant monitor, you would want the output to be as sharp as possible, right?
Having a dependable professional video switcher, you will feel more confident about directing the event. With this switcher on your side during events, you’ll eventually establish yourself as a professional—an expert who can produce high-quality output for any event’s attendees.

2. Loss or misplace of data
Another roadblock for today’s professionals is losing important data. This is a common fear among most creatives—putting in their effort, time, tears, and blood—only for their output to vanish in thin air. See here at 3D HD Gear
How do you even explain delays to an already agitated client?
For example, you’re a commercial director who’s filming a scene in a tight, crowded market area. Your crew had two extra memory cards; however, you’ve used up both of their storage spaces. And you still have three scenes left to film.
The problem is that your deadline is in a few days. Going back to this location just to film those scenes will be another expense at your end.
What a dilemma, right? That is why you have to invest in the right storage devices. You want the big boys who can handle loads of data.
According to the ERAC (Electrical Regulatory Authorities Council), 15 people die every year due to home related electrical accidents. In addition to that, around 300 people are hospitalized each year due to the same reason stated above. As these are accidents, these things mean that they can happen to any household including your own house. So, before calling the electrical service Perth has, read on to this article.
On a report made by the DFES (Department of Fire and Emergency Services), around fifteen thousand residential fires are caused by faulty electrical wirings. Although this number is very alarming, most households take electrical wirings for granted. This is why these mishaps are so prevalent; basically because people fix it when it is too late. It is important to make sure that damaged and cut wires are replaced immediately. All octopus connections should be properly arranged to avoid short circuits. Additionally, every household should avoid overcrowding of wires to avoid accidents.
Electrical Outlets and Plugs
These two things might be minute in stature; however, they are common culprits when it comes to starting a fire. An electrical service Perth has as your choice should be able to ensure that water will not be able to penetrate them. Plugs should be tight as well to avoid fire and other accidents.
In an ideal world, extension cords are not made to be a solution to your house’s lack of electrical outlets. They should only serve as a temporary solution when you are not able to have them at the moment. If you don’t know how to install electrical outlets, have the electrical service Perth has to install them for you. Make sure that the installed electrical outlets have safety covers and are water impenetrable especially during floods and plumbing mishaps.
Electrical Panel Boards
Electrical panel boards serve one purpose: to protect you and your family members from electrical accidents. However, if they fail, that means that your house is more vulnerable to electrical accidents. The panel board is usually composed of fuses and circuit breakers. Ensuring that they are functioning well will benefit you a lot because not only does it protect you from physical harm, it protects your appliances as well making you save money on buying new appliances due to accidents.
Partial discharge testing is one of the most important techniques applied in the protection of electrical assets. It is mainly concerned with the monitoring and the measurement of the quality of the insulation materials that have been used in the cable power systems.
If the power cable insulation mechanism has broken down or is in the process of breaking down, it will produce partial electrical discharges which can be detected, monitored and analyzed using specialized partial discharge testing equipment. The partial discharge testing or PD testing is generally mostly applied in the extruded insulation materials on the cables.
Partial discharge testing can be carried out in two main modes. One form of the testing and the monitoring includes measuring all the discharges that are occurring in the cable system. On the other hand, the testing geared at monitoring a particular spot on a power cable. This will be applicable in cases where you need to locate an individual discharge point in the cable system as opposed to measuring all the discharges in the cable system.
Measurement of the PD
This is one of the most significant tests generally carried out on the power cables before they are released into the marketplace. It is done in order to ensure that they are highly reliable. The tests are carried out at power frequency in order to predict the cable’s behavior when it is deployed in the real world high voltage high-frequency applications.
When testing is done at the factory, the manufacturers generally apply a voltage frequency that is slightly higher than the actual voltage frequency that will be used in the ground in order to guarantee the reliability of the power cable insulations. Low frequency partial discharge testing is also carried out in order to detect the imperfections in the power cables.
But factory tests are not sufficient and may not detect 100% of the imperfections in the cable insulations. Besides, as the cable is used in the real-world environment, it will undergo a slow degradation and create new imperfections that will lead to partial discharges and which may grow into something more serious if it goes unchecked.
