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.

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.

Kubernetes in the Cloud: Strategies for Effective Multi Cloud Implementations

Kubernetes is a highly popular container orchestration platform. Multi cloud is a strategy that leverages cloud resources from multiple vendors. Multi cloud strategies have become popular because they help prevent vendor lock-in and enable you to leverage a wide variety of cloud resources. However, multi cloud ecosystems are notoriously difficult to configure and maintain.

This article explains how you can leverage Kubernetes to reduce multi cloud complexities and improve stability, scalability, and velocity.

Kubernetes: Your Multi Cloud Strategy

Maintaining standardized application deployments becomes more challenging as your number of applications and the technologies they are based on increase. As environments, operating systems, and dependencies differ, management and operations require more effort and extensive documentation.

In the past, teams tried to get around these difficulties by creating isolated projects in the data center. Each project, including its configurations and requirements were managed independently. This required accurately predicting performance and the number of users before deployment and taking down applications to update operating systems or applications. There were many chances for error.

Kubernetes can provide an alternative to the old method, enabling teams to deploy applications independent of the environment in containers. This eliminates the need to create resource partitions and enables teams to operate infrastructure as a unified whole.

In particular, Kubernetes makes it easier to deploy a multi cloud strategy since it enables you to abstract away service differences. With Kubernetes deployments you can work from a consistent platform and optimize services and applications according to your business needs.

The Compelling Attributes of Multi Cloud Kubernetes

Multi cloud Kubernetes can provide multiple benefits beyond a single cloud deployment. Below are some of the most notable advantages.

Stability

In addition to the built-in scalability, fault tolerance, and auto-healing features of Kubernetes, multi cloud deployments can provide service redundancy. For example, you can mirror applications or split microservices across vendors. This reduces the risk of a vendor-related outage and enables you to create failovers.

Guide to Contributing to Jakarta EE 10

This high-level guide outlines some possibilities for Jakarta EE 10 as well as how you can contribute.

Java EE has been transferred to the Eclipse Foundation and Jakarta EE 9.1 is behind us. The next step in the journey is Jakarta EE 10. This write-up outlines some possibilities for Jakarta EE 10 as well as how you can contribute.

Ways of Contributing

There are many ways of contributing to Jakarta EE 10, depending on what your time and interest allow. You can always start simple and get more engaged over time.

You can simply follow a Jakarta EE technology that interests you. The easiest way to do that is by subscribing to its mailing list. All the Jakarta mailing lists are available here. We specifically link the mailing lists for some likely key Jakarta EE 10 technologies below. You should feel free to join discussions that interest you. Contributing your opinion as an end-user is one of the most valuable things you can do.
If you have a specific feature you would like to advocate for, you should do so on the mailing list to start with. It may be necessary to record an issue detailing the feature if it does not already exist. Each project has a GitHub repository where you can record issues. You should be able to find the issue tracker for projects from here. We specifically link the issue trackers for some likely key Jakarta EE 10 technologies below.
If you want to help implement a change in the technology, you should look through the issue trackers and ask to pick up an issue on the mailing list. You can contribute an API change, a TCK change, or a change in one of the technology implementations (such as GlassFish, Jersey, Mojarra, OpenMQ, or EclipseLink). Providing a proof-of-concept if you can is a great way to advocate for change (although this is clearly not an expectation from everyone).
If you are unsure where to start, just get on a mailing list, introduce yourself and say you want to help. There should be a Jakarta EE Ambassador present to engage you. You can also reach out through the Jakarta EE Ambassadors Google Group.
