Monitoring Legacy Virtual Machines, and Its Applications — the “Kubernetes Way”

Kubernetes has indeed become a defacto standard when developing containerized apps as it provides a vast set of functionalities out-of-the-box that helps developers build scalable and resilient systems.

Everything is beautiful if you are developing something from scratch, but we all know that’s not how it works for most companies! As time pass, a lot of legacy systems have become some sort of gigantic monolith monster that doesn’t run on containers, but on Virtual Machines. It’s really hard to refactor those systems for various reasons:

  • Technical reasons (e.g., depends on old operational systems or kernels)
  • Business reasons (e.g., time to market, cost of conversion)
  • Difficulties with vendors (e.g., vendor does not provide the solution in the container format)
  • Or, believe it or not, new applications can indeed still be designed to run on Virtual Machines instead of containers

This shouldn’t stop you from using Kubernetes, and KubeVirt is the right tool for bringing those VMs to the Kubernetes world. KubeVirt is a virtual machine management add-on for Kubernetes. The aim is to provide a common ground for virtualization solutions on top of Kubernetes. With KubeVirt, you can manage Virtual Machines as a Kubernetes resource, similar to pods. You can declare, start, stop, delete, scale, and…monitor them! The Kubernetes way.

In this particular blog post, I won’t be covering KubeVirt itself with too many details, but how to monitor your virtual machines similarly to how you monitor your containers inside k8s. KubeVirt has an awesome user-guide if you want to know more about it.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

(State of Kubernetes and Container Security, 2020)

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Top 5 Strategies for Legacy System Migration

The people who can truly understand the data are the business people who can decide what data to keep and what data can be thrown away. During the mapping exercise, it is important to involve someone from the business team for future backtracking. It is also helpful to record the mapping decisions and their reasons.

The Rising Value of Big Data in Application Monitoring

In an ecosystem that has become increasingly integrated with huge chunks of data and information traveling through the airwaves, Big Data has become irreplaceable for establishments.

From day-to-day business operations to detailed customer interactions, many ventures heavily invest in data sciences and data analysis  to find breakthroughs and marketable insights.

Plus, surviving in the current era, mandates taking informed decisions and surgical precision based on the projected forecast of current trends to retain profitability. Hence these days, data is revered as the most valuable resource.

According to a recent study by Sigma Computing , the world of Big Data is only projected to grow bigger, and by 2025 it is estimated that the global data-sphere will grow to reach 17.5 Zettabytes. FYI one Zettabyte is equal to 1 million Petabytes.

Moreover, the Big Data industry will be worth an estimate of $77 billion by 2023. Furthermore, the Banking sector generates unparalleled quantities of data, with the amount of data generated by the financial industry each second growing by 700% in 2021.

In light of this information, let’s take a quick look at some of the ways application monitoring can use Big Data, along with its growing importance and impact.
