The synergy of Development and Operations Teams is DevOps. DevOps has exponentially grown in recent years, citing numerous benefits that transformed the entire Software Development Lifecycle (SDLC). DevOps has brought Development and Operations teams together on a single platform for better collaboration and improved transparency. DevOps professionals who have undergone a DevOps course may use many tools for different purposes. What are these distinct purposes? The DevOps lifecycle! and they are:
- Continuous Development
- Continuous Integration
- Continuous Testing
- Continuous Monitoring
- Continuous Feedback
- Continuous Deployment
- Continuous Operations
Essential elements of DevOps:
Many tools serve similar purposes in the DevOps Lifecycle. To rate them among the best tools is a difficult job, as each tool solves a particular problem, needs an appropriate team and gives the best results in a tailor-made project. No DevOps tool is a one-size-fits-all type. Check out this DevOps Course tailor-made for professionals who wish to break into the DevOps domain. Let’s first mention the primary elements of DevOps that we will discuss here:
- Source Code Control
- CI/CD and Configuration Management
- Container Platforms
- Cloud Computing and Storage
- Monitor, Alert, and Incident Response
Here I haven’t mentioned some significant elements of DevOps like Live Conference Call, IT Ticketing, Status Page, and Service Updates. I have not included them only to make this list concise and include only the top seven. So without any further adieu, let’s jump to the top DevOps tools.
Top 7 DevOps tools are:
I have selected one tool each for all the elements of DevOps. And also mentioned similar tools in brackets that have a comparable level of acceptance in the DevOps community. So, the top 7 tools according to DevOps Elements are:
Source code control: Git (GitHub, GitLab, BitBucket, etc.)
CI/CD & Config. Management: Jenkins (Ansible, Puppet, Chef, etc.)
- Source Code Control: Git (GitHub, GitLab, BitBucket, etc. )
- CI/CD & Config. Management: Jenkins (Ansible, Puppet, Chef, etc.)
- Container: Kubernetes (Docker Swarm, etc.)
- Cloud Computing & Storage: AWS (GCP, Azure, etc. )
- Monitoring, Alerting & Incident Response: Splunk Cloud (AppDynamics, SignalFx, Raygun, Prometheus, VictorOps, Catchpoint, etc.)
- Testing: Selenium (Gremlin, etc.)
- Communication: Slack (Microsoft Teams, etc.)
Git- Git is a very famous open-source distributed DevOps tool in version control systems that can handle any size of the project. Git tracks your filesystems every time and records the changes made. Git helps in enhancing visibility across the development pipelines and aids in more communication across the teams.
GitHub is the largest repository of open-source projects where developers collaborate.
Jenkins- This tool is used in the CI/CD pipeline and helps in building solid deployment automation. Jenkins is also used for app deployment and configuration management. Relatively, teams also use Ansible in place of Jenkins. And a portion of them uses both these tools suiting different use-cases. Chef is used for Configuration Management, whereas some also use Puppet. So decide the means you will need based on the toolchain, team structure, tool architecture, etc.
Kubernetes- Containers are a critical part of DevOps today. Every organization doesn’t have to adopt containerization. But none can discard the fact that containerization brings efficiency and speed. As with this process, you are splitting an enormous software into small microservices running on containers. What do you get by dividing the heavy software? You get the massive benefit of developing software quickly in a small time window and reliability. In this case, you can either use Docker Swarm or Kubernetes for orchestrating containers.
AWS- Since there is no requirement to choose a cloud vendor on a DevOps team. Choosing one does help them to increase their agility and flexibility. It is a highly advantageous position that these DevOps teams can be in. So, coming to Cloud Vendors, these teams can adopt any Cloud Strategy suiting their needs. Public Cloud, Private Cloud, Multi-Cloud, or even Hybrid-Cloud Strategy. The top three Cloud Service Providers are AWS, Azure, and GCP. And all offer nearly similar services and at the marginal difference in costs.
Splunk Cloud- Many tools can monitor your systems, software, infrastructure, applications, etc., to mitigate any threat or reliability issues. These tools will alert you the moment something trips off. Some of the tools are VictorOps, Prometheus, Raygun, Catchpoint, AppDynamics, SignalFx, etc., that can design visualization on the dashboards for faster incident responses, prepare reports, show metrics like performance, etc.
Selenium- DevOps is incomplete without the testing phase. For testing purposes, we have some of the fantastic frameworks, Selenium, Gremlin, etc. They offer full-scale test automation features. Automation Testing has taken the testing process by storm, as it helps in reducing the time that is lost to Manual testing earlier.
Slack- Communication tools like Slack, Microsoft Teams, and many more, offer a lot of functionalities to the DevOps community. These tools offer you real-time chat capabilities along with other integration options with the toolchain. Some tools offer you the option of running commands and writing scripts all in your chat tool itself. Slack is popular, while Microsoft Teams is gaining popularity among big companies.
All these tools have very high usage across the DevOps community. So, if you wish to enter the DevOps domain, make sure to check out these tools and learn them if needed to break into the DevOps industry.
