Kubernetes is an open-sourced system and automated software deployment technology. Originally designed by Google, the system now belongs to the Cloud Native Computing Foundation. Kubernetes software streamlines the development and management of containerized applications by breaking software down into containers for more accessible launches.
Application containers are aspects of software coding that allow applications to run effectively in any environment. Containers have become increasingly popular as they help applications run more efficiently and allow for consistent updates and improvements.
Kubernetes can streamline your IT operations, but it comes with a bit of a learning curve. Here are five benefits and challenges to consider when it comes to a hosted Kubernetes solution.
Key performance features
Contents
Kubernetes performs several functions that help with operational efficiency within application development. Some features include:
Automated rollouts (and rollbacks)
Kubernetes automatically adapts by rolling out new changes to existing applications or configurations. If something goes wrong, it will roll back and eliminate that change.
Self-improvements
Kubernetes automatically recognizes faulty containers and either eliminates or replaces them.
Environmental flexibility
Kubernetes operates similarly across different servers and platforms, making it a highly versatile tool for transporting data and technology. The software is capable of running on virtually any platform.
Easy to add features
Users can add new features and extensions to Kubernetes clusters without changing the source code.
Though Kubernetes is designed to make your life as an IT professional easier, that doesn’t mean that you can’t use further solutions to help manage your Kubernetes platform. Tools like Rancher Hosted can help you leverage your hosted Kubernetes architecture to its fullest potential.
Scaling
Another benefit of Kubernetes is the role it plays in scaling operations. One of the core strengths of the Kubernetes platform is its ability to automate tasks and system updates. Kubernetes orchestrates and directs application containers, eliminating time-consuming manual tasks. With this technology, systems can adapt and grow much faster.
Security
As is the case with integrating most technology, tracking security concerns for Kubernetes are imperative. Constant updates and configurational changes that make the technology compelling and dynamic also represent significant security challenges.
Some potential obstacles include:
- Compromised images
- Compromised containers
- Lack of visibility (if dynamic container changes are unmonitored)
- Compliance Concerns
The pros of Kubernetes can outweigh the cons, but that doesn’t mean you should go into your deployment unaware of the potential risks.
Data storage
There are a few different storage methods during the application development and management process. One includes persistent data, which logs and captures everything. Another is ephemeral data, which is more temporary.
The constant creation and deletion of containers in Kubernetes can impact specific applications. This guideline is particularly true when it comes to storing persistent data. Using ephemeral data can help eliminate inconsistencies within containers and is the default setting.
Drawbacks
To weigh whether or not to use Kubernetes, IT professionals should access their current application configurations and weigh out the necessary updates. There are clear benefits to Kubernetes in terms of productivity and stability at the forefront. However, that doesn’t make it the right fit in every case.
Kubernetes is a complex system that may not be right for simple application technology. Implementing Kubernetes is also an extensive process. More advanced technology systems often need to be changed or adapted to run Kubernetes. Higher costs may also be a consideration for smaller companies.
Wrap Up
When it comes to the complex nature of Kubernetes technology, there is a lot for IT professionals to consider. It will take a skilled and knowledgeable team and constant monitoring and surveillance to run successfully.
