Periodic Table of DevOps Tools

What is the DevOps Periodic Table?

It’s a framework where various DevOps tools are categorized and arranged in groups and categories based on their characteristics or roles within the DevOps methodology.

The main aim of the DevOps periodic table is to provide a visual representation that helps the DevOps teams understand the interconnected nature of DevOps practices.

In other words, it’s a grouping of DevOps tools arranged according to their abilities and costs in various categories. Some of the important and well-known DevOps tools include Jenkins, Docker, Git, Kubernetes, Puppet, Ansible, Gradle,Docker,Github etc to name a few.

The DevOps periodic table showcases the DevOps tools list across various categories ordered by their functionality and also the pricing model (Open Source, Free, Freemium, Paid, Enterprise). 

Every single element in the Periodic table shows a general aspect of DevOps as like Automation, Collaboration,Continuous Integration, Monitoring, Security etc. These all elements of periodic table are merge and interact with each other to build an overall approach to DevOps (Development & IT Operational )

What is Container Monitoring? Popular Container Monitoring Tools 

The use of container technology is at its peak. The benefits of containers for cloud-based microservices are infinite. Container Monitoring is the process of tracing the performance of applications that are built on a microservices architecture. Containers are complex and more challenging to keep an eye on compared to traditional applications running on virtual servers.

Monitoring the performance of containerized applications to ensure application continuity is crucial. Monitoring becomes more effective through analyzing metrics, obtainer from any sources like host and demons logs, and monitoring agents installed on each node.

Container monitoring tools track container performance, collects event data, and measures the effects of container-sharing resources. Now Monitoring practices can be either proactive, reactive or adaptive. While Proactive monitoring sets protocols to prevent container failure, in Reactive monitoring we alert users by raising events when the containers fail. Adaptive monitoring continually assesses container performance and impacts from new components.

Importance of Monitoring Docker Containers

Like any other technologies, Containers are subject to performance degradation. The health of containerized applications directly impacts the health and business efficiency of a business. Monitoring application performance ensures that both the containerized applications and the infrastructure are always at optimum levels.

Monitoring Docker Containers helps in:

  • Detect and solve issues at an early stage.
  • Proactively avoids the risks at the production level.
  • Implement changes safely as the whole environment is monitored.
  • Optimize resources allocation.
What Resources to monitor

Host based Metrics

  • Host CPU
  • Host Memory
  • Host Disk Space
  • Total Number of Running Containers

Container-based metrics

  • Container CPU – Throttled CPU Time
  • Container Memory Usage
  • Container Memory – Fail Counters
  • Container Swap
  • Container Disk I/O

How DevOps can benefit from the Open source

Around 2009, the term DevOps introduced an approach that enhances the collaboration between developers and operations groups. It came as a successor to the Agile method and ensured improvement to the Application Lifecycle Management process. You can consider DevOps as a strategy or principle that every company should implement within their delivery pipeline.

To implement DevOps, you should have the right tools and processes at your disposal to make it work efficiently. There are a variety of open-source DevOps tools that help in streamlining the development and deployment process. These open-source tools are built with enhanced collaboration that improves performance and allows you to handle different market needs.

Why do DevOps need Open-source?

Well, many companies across the globe have started adopting the DevOps approach for effective and faster delivery. However most companies still shy away from implementing open-source software within their organizations to enhance the DevOps approach. Also, companies restrain their developers from contributing to open source libraries, so they miss a huge opportunity for success.

We are sharing some  key reasons why a company should focus on the Open-source adoption for Devops implementation.

♠ Open-source is Free or low-cost

Open-source means it is available freely or at a lower cost than other closed-source systems.

♠ Based on open standards

With open-source, you can find each tool, source code, and related troubleshooting documents easily. If you are still using traditional proprietary software, it will be difficult for your organization to evolve.

♠ Open-source is self customizable

Open-source offers customizability where you can use tools and products that are way more efficient and light-weight than other available closed-source options. You can freely choose your framework and easily migrate and automate processes with open-source tools and frameworks.

♠ The open-source community is expanding

The open-source community is now expanding, with millions of contributors and developers writing open code and development. Now companies are even supporting its exposure to their DevOps process. By joining open-source, you will become part of the most dynamic group that provides a better solution for every problem.

♠ No Vendor monopoly or Vendor lock-in

Since open-source tools are free from any proprietorship or licensing from any vendor, there is definitely no pressure of monopoly or being vendor locked-in. Whenever you feel to opt out of the open-source tool, you can move out without any restrictions.

♠ Abundance of Talent pool

Since open source software and tools are free and easily available, the number of people with an expertise on popular open source solution is more as compared to licensed tools( because fo the cost involved). So when looking for available expert talent pool in the market for your Devops toolchain, you have higher chances of success with open-source solutions.

How DevOps success aligns with Open-source

There is no doubt that opting for open-source as a part of your DevOps process is beneficial to your organization. But if you are still using highly-proprietary and old traditional IT solutions, you may not achieve the success you are working for. Open source has opened the gate for DevOps to work efficiently. Below are the reasons why DevOps success aligns with the Open-source system, tools, and practices.

  • DevOps groups should go for open-source because the tools and techniques available in the open-source community are either off the shelf or built at some other organization. This will eventually save you time and cost of developing the required tools at your end.
  • If you avail open-source, then you can choose any of the open-source frameworks to work on. You can easily migrate your project from one framework to another without any proprietary lock-in or vendor secrets. It allows your software delivery agile, which is essential in the DevOps process.
  • DevOps mainly focuses on the visibility of the project or application progress within the team members. If you add the open-source within the DevOps process, it ensures the visibility is maintained even to the code level of all the tools you use.
  • Suppose we get any problem during continuous delivery. In that case, there is no time that you contact proprietary vendors to resolve the issue as proprietary tools require expertise to look into the troubleshooting process. But if you go with open-source, you can resolve the issue by yourself as most of the problems are documented publicly for reference.
  • With closed systems, you cannot leverage various tools you are using by integrating them and making the system entirely automated. But with an open-source system, integration and automation are pretty efficient and straightforward.
Common Open-source DevOps tools

You can accelerate an existing system by using open-source tools within your DevOps. Below is the list of the open-source DevOps tools.

Ansible

This tool offers software-related services like application deployment, configuration, etc. It allows you to automate IT tasks. You can easily integrate it with other DevOps tools. You can find its free version on GitHub, where Red Hat offers three different paid versions of Ansible.

Watir

Chef

If you want to handle both traditional and cloud environments using a single tool, Chef is the right choice. This tool comes with the development kit that allows you to deploy and test the automation code locally before deploying it to production.

Docker 

Docker offers portability due to its containerization technology that transforms IT environments. It packages libraries, tools, runtime everything required for an application to run irrespective of the deployment location.

Git

This open-source tool helps to maintain the source code and to host open-source projects. Git stands out of other tools due to its ability to handle merging and branching. This tool is used by many developers and has become popular in recent years. It offers plugins to integrate it with Jenkins for supporting deployment and integration.

Bitbucket

Similar to GitHub, BitBucket is another tool that helps manage project code throughout the SDLC cycle. While the core functionality of BitBucket resembles that of GitHub, features such as easy integration with Jira and Trello, inbuilt CI/CD functionality tend to give this tool by Atlassian an edge.

Puppet

With Puppet, you can follow a standard way of managing and delivering software. Puppet enhances audibility, reliability, and agility. It offers continuous automation and delivery during complete SDLC. With the introduction of various new features, it allows you to handle dynamic systems with great ease.

Prometheus

It is an open-source systems monitoring and alerting toolkit.It comes with a dimensional data model, flexible query language, efficient time series database and modern alerting approach

These tools will help to bridge the gap between the development and production environment. You can choose any tool that suits your business requirement.

Terraform

Best Open Source.. Monitoring an application’s current state is one of the most effective ways to anticipate problems and discover bottlenecks in a production environment. But it is also currently one of the biggest challenges faced by almost all of the software organizations across the globe. [Best Open Source]

Why Kubernetes is considered as the De facto standard for container orchestration?

Kubernetes has taken the container ecosystem by storm, and for good reasons. Kubernetes functions as the brain for your distributed container deployment. Kubernetes is a production-ready, open-source platform designed by Google’s using its accumulated experience in container orchestration.

Kubernetes has over 58K stars on GitHub & 2200+ contributors around the world. With the new ways of building & running applications, monitoring and observability strategies need to change.

Also monitoring Kubernetes, both the infrastructure platform and the running workloads, is on everyone’s checklist as we evolve beyond day zero and move into production.

What to Monitor?

We can try monitoring the following Kubernetes  pod, node and cluster level metrices:

  • Container CPU and Memory Usage
  • Kubernetes Pod CPU and Memory Usage
  • Node CPU and Memory Usage
  • Namespace CPU and Memory Usage
  • Cluster CPU and Memory Usage
  • Container CPU and Memory Requests
  • Pod CPU and Memory Requests
  • Node CPU and Memory Requests
  • CPU and Memory Limits at Pod, Node and cluster levels
  • Kubernetes Resource Capacity

So here we bring for you some of the most popular Open-source monitoring tools to work with Kubernetes.

1. Prometheus


Originally built at the sound cloud, Prometheus is a monitoring and alerting toolkit. It is quite popular in the development community. Now, it is governed by the CNCF (Cloud Native Computing Foundation). Prometheus simplifies the process of pulling numerical metrics based on a time series from a given metrics endpoint. 

It has three elements: Prometheus server, Alert manager, and Exporters. Prometheus servers look after service discovery and pulling metrics from the exporters. The alert manager is responsible for setting up alert rules, analyzing the data in the Prometheus Db. It sends alert messages to multiple receivers if a certain rule is triggered. Exporters are independent containers that can be run on your target resource to generate & export metrics via metrics API. 

Prometheus is developed to collect time-series data via a pull model over HTTP. Here, multiple modes are available for graph and dashboard support.

2. Grafana


You can monitor your Kubernetes cluster’s performance using Grafana. It is mostly used for matric analysis and visualization suite. It allows creating custom dashboards using data taken from multiple sources. 

The monitoring capabilities of Grafana include:

  • Cluster metrics: Pod, capacity/usage, memory capacity/ usage, CPU capacity/usage, Disk capacity/usage, an overview of nodes, pods, and containers.
Node Metrics: CPU, memory available, Load per CPU, Read lops, write lops, %Util, network traffic/second, packets/second, error/second.
  • Pod/container Metrics: Memory usage, Network traffic, CPU usage, Read lops, write lops.
Grafana offers an associated product called ‘LOKI’. Loki aggregates logs in Kubernetes and integrates well with the Grafana UI.
3. The ELK Stack




The ELK or Elastic stack is one of the most popular open-source solutions for logging Kubernetes. The ELK consists of the following things:

  • Elastic search- scalable and well-performer. It can handle the storage and search across millions of docs.
  • Logstash- Aggregate and process logs and send the processed data for storage.
  • Kibana- It is an analysis interface to help users make sense of data.
  • Beats- These are the lightweight data shippers.

The enterprise version of ELK stack ships with X-pack, a set of additional tools that enables reporting, alerting, and role-based access control (RBAC). You need to use the previously mentioned enterprise version of the ELK stack to enable RBAC.

4. Fluentd


Fluentd is governed by a cloud-native computing foundation (CNCF). It is a specialized data collector that unifies data collection & consumption. Fluentd helps to better understand & use of data.

Additionally, Fluentd offers built-in metrics and general purpose output interfaces for centralized collectors. It is quite popular among Kubernetes users to Logstash’s facilities, especially those performances-related. Fluentd is a high performing, scalable &reliable.

It is quite easy to add new inputs or outputs with very little effect on performance. It uses disks or memory for buffering and queuing to handle transmission failures or data overload. It supports multiple configuration options to ensure a more resilient data pipeline.

5. cAdvisor




cAdvisor is used to collect, process, and export resource usage and performance information about running containers. Like other agents, cAdvisor is not deployed per Pod but on the node level. It’s a basic tool but a very useful one.

cAdvisor is built into Kubernetes and integrated into the Kubelet binary. It automatically detects every running container on a machine and collects system metrics like memory, CPU, network, etc.

cAdvisor is capable to support multiple endpoints despite having limited functionality. However, there are some cons of cAdvisor like it’s very basic, lacks analytical depth, and has limited functionalities.

6. Kubewatch

Kubewatch watches the specific Kubernetes events and pushes notifications on these events to various endpoints. In simple words, Kubewatch is the go-to tool to receive push notifications on available collaboration applications or notification channels. 

Kubewatch is easy to configure and can be deployed using either helm or a custom deployment. It will take care of changes made to specific Kubernetes resources that you ask it to watch, like daemon sets, deployment, Pods, replica sets, replica controllers, services, secrets, and configuration maps. 

Users need to run it in their K8s cluster, and the event notifications will be received via webhooks.

7. Kube-Ops-View

Kube-Ops-View is not exactly a monitoring tool. It can’t be used to monitor and alert on production issues, it can give you a nice operational picture of your Kubernetes clusters. It will also have a look at the different nodes deployed and their status along with different Pods running on the nodes.
Kube-Ops-View provides a common operational picture for multiple K8s clusters. It shows the capacity and resource usage for nodes and individual pods with animation. However, it is not a replacement for Kubernetes Dashboard or a monitoring solution. It simply helps the users to quickly figure out the usage metrics without doing too much hustle.

8. Jaeger

It’s an end-to-end distributed tracing solution. Jaeger is widely acknowledged by Kubernetes practitioners as monitoring and troubleshooting best practices. The brief history of Jaeger is that it was developed by Uber, inspired by OpenZipkin and Dapper, and donated to CNCF. 

When a service failure occurs, you have no idea how the requests have gone from service to service over the network to complete a single business transaction. Debugging is extremely difficult in such conditions. Jaeger user tracing to enable root cause analysis, performance, and latency optimization. Jaeger is easy to use and provides a seamless user interface along with different instrumentation options.

9. Weave Scope

Weave Scope is a troubleshooting and monitoring tool for Docker and Kubernetes. It was developed by Weaveworks. Weave Scope allows you to gain operational insights into your Kubernetes clusters. It takes a few steps ahead of Kube-Ops-View by providing a much easier and nicer user interface. 

It also provides the ability to manage containers and run diagnostic commands within the interface. Users can see the application, monitor the infrastructure. It is deployed on, and the relationships between the different components. 

Weave Scope is an effective tool for gaining context on your deployment. The only drawback of Weave Scope is that it lacks analytical depth.

10.  Kubernetes Dashboard

It’s a Web-based, UI add-on for Kubernetes clusters. Users can create and manage workloads as well as do discovery, load balancing, configuration, storage, and monitoring. Kubernetes dashboard offers numerous features and is quite useful for small clusters & for people starting to learn Kubernetes. 

This tool offers different views for CPU and memory usage metrics aggregated across all nodes. This Dashboard is widely used to monitor the health status of workloads like pods, deployments, replica sets, etc. the installation process is quite easy and can be done using readymade YAML files.

11.  Kube-state-metrics

Kube-state-metrics is a Kubernetes-native metrics service designed to listen to the Kubernetes. It generates metrics without any modification to Kubernetes API. Hence, users can rely on the same grade of stability as offered by Kubernetes API. 

Kube-state-metrics is an extremely essay to use and is only a metrics service. It requires a few more bit and pieces to become part of a complete monitoring solution for Kubernetes. 

Kube-state-metrics exports the metrics on the HTTP endpoint in a plain text format. Real-life Kubernetes practitioners recommend Kube-state-metrics if someone is struggling to use Prometheus for K8s monitoring.

Conclusion

In this blog post we have discussed the importance of Kubernetes monitoring and also outlined an extensive list of open-source monitoring tools for kubernetes. Finally choosing a tool depends on your monitoring needs and use cases. Open-source solutions have the advantage of being backed up by large communities driven to improve existing solutions.
