In the quest to build best architectures, we have conducted extensive research in order to establish the best DevOps tools for companies. Due to our vast experience in the IT field whereby we are concerned with infrastructural upgrade, we have managed to come up with the right decision on the best tools to include in DevOps toolkit. From building a petabyte-scale, data analytics infrastructure, architectures , tools , and processes have become key components of our technology and operations. As a company provides DevOps services, we have carefully done our selection process through a rigorous benchmarking process and we’re always committed to improving our tool selection process.
The following are the most essential tools to include in a DevOps toolkit:
Jenkins is a very popular DevOps tool. Although its not the best in terms of speed and other factors , its ease of use and network of plugins and add ons make it to stand out. This tool is optimized to make customization easier. Jenkins is configured to perform various functions such as building code, creating Docker containers, running tests and push to production. Just like any other tool, Jenkins has its shortcomings and this are pointed out in its scaling and performance. Other good solutions are Travis and CircleCl, which are both hosted solutions that don’t require any maintenance
Docker can be best described as a transformative tool in the IT industry. We use Docker in production of a greater part of services. Basically, this tool has completely made configuration management easy. Besides, it’s used to control various issues and scaling. This way, it eases the process of moving containers from one place to another. However, like other tools that I have already mentioned, Docker has a few negative aspects. Our team notes that it has some downsides. Our company has managed to build our SaaS solution with a twelve-layer pipeline of data processing. Using both Docker and Jenkins, our team has managed to run a full pipeline across all layers on a single Mac. One of the downsides of Docker is that it takes a relatively more amount of time to build even small containers. However, our company is fully committed to see that our developers like the tool so that they are in a position to work optimally. The intensive management associated with storage, security, networking and everything surrounding containers poses some challenges.
This open-source DevOps tool is well-known for giving the best service as well as configuration in current and flexible applications that are developed from micro-services. Consul applies modern technology to provide internal DNS names for service. Basically, this tool functions as a conduit to help you sign and register names and gain entry to specific names as opposed to specific machines. In a case where you have a collection of multiple machines , this tool allows you to register them as a single entity under Consul and access the cluster without any complications. Generally, this tool is efficient although it requires more improvements.
Ansible is a simple configuration management tool that is similar to Chef and Puppet. Although they are quite complex to use, Chef and Puppet have more features. Today, its common to find DevOps engineers substituting configuration management using Ansible with the option of killing and spinning new application instances using a Docker container. Docker creates a situation where we don’t see the need to upgrade machines and instead we choose to spin new machines . This reduces one’s need to upgrade EC2 cloud instances. This tool is generally used for deployment configuration. It is used to push changes and re-configure newly-deployed machines. Additionally, it features a great ecosystem which has an easy option to write custom applications.
Puppet offers an exceptional way of automating IT with an aim to discover, configure, and manage company infrastructure. This tool is very popular among system administrators as it helps them to work faster and more efficiently.
Chef is a great tool that helps to convert infrastructure into code. The good thing about Chef is that it operates from any kind of IT environment . Moreover, it automates the configuration , deployment and management of infrastructure regardless of its size.
Prometheus & Icinga
Just like InfluxDB and Graphite monitoring systems, the Prometheus, an open-source monitoring system tool built by Soundcloud stores all its data in a time series database. The main advantage of this tool is that it produces more accurate reports. However, Prometheus has one complication in the sense that it makes it difficult for system administrators to polish up the definition of their metrics as it offers a multi-dimensional data-model and a powerful query language. The Prometheus project also incorporates two other tools: PromDash and experimental AlertManager. PromDash is a browser-based tool that develops custom dashboards and an experimental AlertManager that is used to send alerts via e-mail, Flowdock, Slack, and HipChat . Another tool worth mentioning is Icinga which was originally created as a branch of Nagios. Developers intend to improve Nagois by incorporating new features and a modern user experience. However, various issues are being raised on the efficiency of Nagois within the open source community but we’re not going to substitute it with anything else as we are contented with its performance. But still, we may consider switching to advanced tools such is Icinga in the future if need be.
Git is a renowned source management tool in the IT field. Git (GitHub) was developed 10 years ago when the Linux community was in need of a Source Control Management Software (SCM) to support distributed systems. After a series of tests we found out that GitHub works well with our team. This tool has many advantages including great forking , pull request features , and many plugins that can connect with Jenkins to speed up integration and deployment. All in all, GitHub is a very valuable tool in the modern IT world.
With the IT industry advancing at rapid rate, numerous open source tools have been developed in the DevOps world. From our intensive research, we can confirm that the aforementioned tools are efficient and reliable. These tools are therefore recommended for DevOps engineers.
