How an organisation uses tools to achieve efficient, scalable, automated workflows defines the role of a DevOps professional. A DevOps Bootcamp, however, teaches students how to use these tools and how to create powerful CI/CD pipelines, how to manage containerised environments, and how to orchestrate services. We look at the tools you’ll master in a DevOps Bootcamp and why they’re so important in the tech industry.
Docker Tool The Foundation of Containerisation
Docker is the heart and soul of modern application deployments, allowing developers to take entire applications and their dependencies in lightweight, portable units.
Key Characteristics
- Isolation: Containerised applications and their packages so that they can execute in isolated containers that ensure constant behaviour across different environments
- Portability: Containers are deployable on any system, whether local, cloud, or virtual machine-based.
Why Is It Essential?
It eliminates the “it works on my machine” problem and thereby becomes a must-know tool for aspiring DevOps engineers: it simplifies software delivery.
Jenkins An Automating the CI/CD Pipeline
Jenkins is an open-source automation server that is crucial to the realisation of continuous integration and delivery pipelines.
Key Characteristics
- Customisability: Provides hundreds of plugins to support building, deploying, and automating projects.
- Pipeline as Code: Enables users to define CI/CD processes in code, which ensures repeatability and version control.
Why Is It Essential?
It assists in the bending development cycles by automating redundant tasks and making sure the software arrives on the production platform as before without a lot of human involvement.
Kubernetes An Orchestrating Containers at Scale
Kubernetes is a system that manages and orchestrates containerised applications over a cluster of machines.
Key Characteristics
- Scaling: Scales applications based on demand automatically.
- Self-Recovery: Restarts dead containers and replaces them without the administrator’s intervention.
Why Does It Matter?
In managing large containerised environments, Kubernetes offers Kubernetes, which ensures high availability and fault tolerance and must, therefore, be an essential item in cloud-native DevOps workflows.
Ansible The Simplifying Configuration Management
Ansible is the automation tool for provisioning and managing software and configuring applications.
Key Features
- Agentless: Doesn’t need any agent software in target machines; reduces overhead.
- Declarative Language: Uses YAML to write configuration, thus friendly with the user.
Why Does It Matter?
Ansible automates infrastructure setup, maintaining consistency in settings and minimising chances of errors in configuration.
Git An Version Control and Collaboration
Git is a distributed version control system that allows us to find out what changed, when and by whom.
Key Features
- Branching and Merging: Allows developers to work on features independently and integrate them without any problems.
- History Tracking: Tracks all the changes made so that it becomes easy to debug and roll back.
Why Is It Important?
Git ensures that teams can collaborate efficiently, maintain a clean codebase, and avoid conflicts during integration.
Prometheus and Grafana for Monitoring and Visualisation
These tools, in coordination, offer system and application monitoring and visualisation.
Key Features
- Prometheus-Collect metrics from systems. Store metrics in a time-series database.
- Grafana: Build interactive dashboards for visualisation to identify the problems.
Why Is It Important?
Only effective monitoring ensures prompt issue detection and issue resolution to guarantee system reliability and performance.
Terraform the Infrastructure as Code (IaC)
Terraform is an IaC tool that declares and provisions infrastructure in the cloud.
Key Features
- Multi-Cloud Support: Seamless support across cloud providers AWS, Azure and Google Cloud.
- State Management: Tracks the current state of infrastructure to be sure updates are applied correctly
Why Is It Essential?
Terraform enables teams to manage complex infrastructure setups efficiently while ensuring repeatable and scalable deployments.
Conclusion
A DevOps bootcamp is more of a hands-on experience offering the theoretical knowledge of industry-leading Docker, Jenkins, Kubernetes, etc. With these technologies, master students can streamline workflows to automate processes and scale applications almost effortlessly.
The London School of Emerging Technology (LSET) is offering a comprehensive DevOps Bootcamp that combines the best of theoretical foundations with real-world projects. The bootcamp is 25% off until New Year (December 31). It’s, therefore, the right opportunity to boost your DevOps skills. More information about the bootcamp is here: LSET DevOps Bootcamp.
