Terraform is an open-source infrastructure as code software tool created by HashiCorp.

• Terraform allows users to define and provision infrastructure using a declarative configuration language.

• It supports multiple cloud providers such as AWS, Azure, Google Cloud, and more.

• Terraform uses 'terraform plan' to create an execution plan and 'terraform apply' to apply the changes.

• It helps in automating the creation, modificatio...read more

Azure DevOps is a set of development tools provided by Microsoft to help teams collaborate and deliver high-quality software.

• Azure DevOps includes services such as Azure Repos, Azure Pipelines, Azure Boards, Azure Artifacts, and Azure Test Plans.

• It allows for version control, continuous integration/continuous deployment (CI/CD), project management, and testing.

• Teams can plan, build, test, and deploy applications using ...read more

CI/CD pipelines automate the process of building, testing, and deploying code changes.

• CI/CD stands for Continuous Integration/Continuous Deployment

• Automates the process of integrating code changes into a shared repository and deploying them to production

• Helps in detecting and fixing integration errors early in the development process

• Enables faster delivery of software updates and improvements

• Popular tools for CI/CD pip...read more

Docker is a platform for developing, shipping, and running applications in containers. Kubernetes is a container orchestration tool for managing containerized applications across a cluster of nodes.

• Docker allows developers to package applications and their dependencies into containers for easy deployment.

• Kubernetes automates the deployment, scaling, and management of containerized applications.

Kubelet is the primary node agent that runs on each node in a Kubernetes cluster.

• Kubelet is responsible for managing the pods on the node, ensuring they are running and healthy.

• It communicates with the Kubernetes API server to receive instructions and report the status of the node.

• Kubelet also monitors the health of the node and takes actions if necessary, such as restarting pods.

• It interacts with container runtimes li...read more

Config map and secrets are Kubernetes objects used to manage configuration data and sensitive information.

• Config map is used to store non-sensitive configuration data in key-value pairs

• Secrets are used to store sensitive information like passwords, API keys, and tokens

• Both config map and secrets can be mounted as volumes or used as environment variables in Kubernetes pods

Application load balancing is a method used to distribute incoming network traffic across multiple servers.

• It helps improve the performance and reliability of applications by evenly distributing the workload.

• Load balancers can be hardware-based or software-based.

• Common load balancing algorithms include round-robin, least connections, and IP hash.

• Examples of load balancers include NGINX, HAProxy, and Azure Load Balancer

CI/CD pipeline automates the process of integrating code changes and deploying them to production.

• Continuous Integration (CI) involves automatically building and testing code changes as they are committed to a shared repository.

• Continuous Deployment (CD) involves automatically deploying code changes to production after passing tests in the CI phase.

• CI/CD pipelines help in achieving faster and more reliable software del...read more

Autoscaling in cloud allows resources to automatically adjust based on demand, optimizing performance and cost.

• Automatically adjusts resources based on demand

• Optimizes performance and cost

• Commonly used in cloud environments like Azure, AWS, and Google Cloud

• Examples include scaling up virtual machines during peak traffic times and scaling down during off-peak hours
