Kubernetes & Helm Kubernetes, the container orchestration platform, is one of the most transformative tools in SRE automation. In 2025, Kubernetes remains an essential tool for automating deployment, scaling, and management of containerized applications. Kubernetes automates much of the manual work involved in managing containerized applications, such as load balancing, service discovery, scaling, and rolling updates. Helm, the package manager for Kubernetes, takes Kubernetes automation a step further. Helm simplifies the deployment of applications on Kubernetes by packaging them into reusable charts, which define everything needed to run an application. Helm charts make it easy to automate the process of deploying, managing, and upgrading applications across different environments. SRE Training Online With Kubernetes and Helm, SREs can automate the deployment of complex microservices architectures, ensuring consistency and scalability across environments. These tools not only reduce the manual effort needed to manage containers but also provide enhanced flexibility in scaling and updating systems, which is crucial in the fast-moving tech landscape of 2025. 4. Ansible Ansible is a well-established automation tool that is still widely used by SRE teams in 2025. It provides a simple, agentless automation solution for tasks such as configuration management, application deployment, and orchestration.

3. Ansible’s YAML-based playbooks make it easy for SREs to define the steps required to configure and deploy applications or systems. The simplicity of Ansible allows for seamless integration into CI/CD pipelines, where it can be used to automate deployment workflows and infrastructure provisioning. One of Ansible's strengths is its ability to integrate with a variety of systems, including cloud platforms, virtual machines, and networking devices. For SREs, this means automating tasks across heterogeneous environments, ensuring that systems are correctly configured and compliant with standards without requiring manual intervention. Ansible is also used for incident remediation, where playbooks can be written to respond automatically to specific failure conditions, such as restarting services or scaling resources up or down in response to load changes.
