8 Cloud-based Kubernetes and Docker Monitoring Solutions
An efficient Kubernetes and Docker monitoring solution can help you measure crucial metrics of your applications, including their health, performance, speed, cost, and resource utilization.
In fact, in the modern DevOps infrastructure, both Kubernetes and Docker hold significant positions. Docker lets you containerize your applications and run them, while Kubernetes allows you to manage those containers.
Although you can use a Docker CLI to manage the containers that can range thousands in numbers, it’s highly challenging.
That said, using Kubernetes and Docker for the above processes can be a huge relief and make things simpler. But it’s not a cakewalk. It needs you to observe the containers properly and analyze them to ensure the application performs well without hitches.
And to make that possible, you must monitor the applications and containers, log the activities, trace inefficiencies, and debug them to ensure the services run with optimal performance, uptime, and reliability.
In this article, I’ll discuss some of the reliable Kubernetes and Docker monitoring solutions so you can optimize your applications.
But first, let’s talk about,
What Are Kubernetes, Docker, and Containers?
Kubernetes is an open-source system that enables you to orchestrate or manage containers for automating application deployment, management, and scaling. It was developed on June 7th, 2014, by Google, but now the Cloud Native Computing Foundation maintains it.
Kubernetes works with different container runtimes like Docker, CRI-O, and Containerd. A lot of cloud services provide a Kubernetes-based PaaS or IaaS where you can deploy Kubernetes.
Docker refers to a set of various PaaS or Platform-as-a-Service products that leverage OS-level virtualization to offer software or applications in packages known as containers. And the software hosting the containers is Docker Engine.
Docker was developed by Docker Inc. and released in 2013. It can package software applications along with their dependencies. It also stores them in a virtual container that can run on Windows, Linux, and macOS. This enables the software to run in various locations on a public cloud or on-premises.
Containers are executable units of software where application code gets packaged with its dependencies and libraries so that it can run anywhere on the cloud, traditional IT, or desktop.
Containers leverage OS virtualization to allow multiple applications to share the operating system by separating processes while controlling the resources like CPU, disk storage, and memory that those processes could access. They are isolated from each other and bundled with their respective libraries, code, software, and configuration files.
However, they can still interact via a defined channel. Furthermore, all the containers use a single OS kernel, and they consume fewer resources compared to a virtual machine (VM).
What Do You Mean by Kubernetes or Docker Monitoring?
Kubernetes or Docker monitoring means observing and analyzing a Docker or Kubernetes-based software regularly to optimize its performance, health, cost, and efficiency. Software teams perform this by measuring the metrics that the application outputs. These metrics may include:
- Kubernetes cluster metrics like running containers, state, resource consumption, and network input/output
- Running and deploying Kubernetes pods
- CPU, disk, and memory utilization
- API server, data stores, scheduler status, and controller life cycle metrics
- Cost per cluster, team, and product
Monitoring is a crucial part of gaining observability in application development. And analyzing metrics like these can help you obtain valuable information.
Why Monitor Kubernetes and Docker Containers?
If you don’t monitor your Kubernetes and Docker systems, it can be difficult to tell whether all the processes are running well due to limited observability or visibility into vital metrics. It can also be challenging to figure out issues that may impact your application or take immediate action within time before the situations become worse.
As a result, it can invite various risks in terms of security, data privacy, app performance and health, network, and cost.
Therefore, monitoring your application is necessary. But Docker and Kubernetes monitoring can be challenging as it requires an efficient strategy.
This is why you need an excellent monitoring solution to ease the process for you. The monitoring tool can offer wider observability into each aspect of your application. To ensure the application performs optimally, you can track critical metrics like health, cost, resource utilization, and more.
Let’s see what all benefits you can expect out of a good monitoring tool in detail.
Identifying and Resolving Issues Proactively
An efficient monitoring tool for your Kubernetes and Docker systems can monitor all the processes proactively. It will provide you with accurate insights on every little change and the running processes.
With 360-degree visibility, you can easily track the inefficiencies that can impact the systems. On catching any issues, bugs, or errors, the tool will also inform you quickly so you can fix the problems before any damage occurs. Plus, it can keep an eye on systems to help prevent system outages due to unnecessary resource utilization, which in turn, saves cost.
Optimizing App Performance
One of the main reasons for using the monitoring tools is to improve application performance. The tools work by gathering insights and dependencies of an application, creating a performance benchmarking.
These insights help the tool identify abnormalities and root causes of the issues and inform the same to the software teams. This allows the team to take quick actions and steps to improve the app performance.
Implementing Changes Safely
As the monitoring tools can observe the issues when they arise and notify the team in real-time, you can understand the app vulnerabilities quickly and resolve them.
Otherwise, if you don’t have such tools available, any change you may perform to the app can worsen its performance as you don’t know the underlying issues in the application. These vulnerabilities can impact the application’s security and make it prone to viruses and malware. And in this age of cyber threats, you certainly can’t afford that.
So, use a monitoring tool to keep your apps secure and robust so you can implement changes easily and make them live.
When it comes to choosing Kubernetes and Docker monitoring tools, cloud-based solutions can be a great alternative to a self-hosted monitoring solution. It’s because it will give you the power of the cloud so you can enable real-time monitoring no matter where you are, resolve issues immediately, make changes, and avail many more benefits.
