Docker offers several benefits that make it a popular choice for modern application development and deployment.
✅ No Pre-allocation of RAM → Docker containers use only the memory they need, optimizing system resources.
✅ CI/CD Efficiency → Containers ensure consistency across all stages of development, testing, and deployment. Docker enables you to build container image and use the same image across every step of the deployment process.
✅ Cost-Effective → Reduces infrastructure costs by using fewer system resources compared to traditional VMs.
✅ Lightweight → Containers share the host OS kernel, making them more efficient than VMs.
✅ Flexible Deployment → Can run on physical hardware, virtual machines, or in the cloud.
✅ Reusable Images → The same image can be used multiple times across different environments.
✅ Fast Startup → Containers take seconds to launch, unlike VMs that take minutes.
Despite its advantages, Docker also has some limitations.
❌ Not Ideal for GUI Applications → Docker is mainly designed for command-line applications, making it less suitable for GUI-based applications.
❌ Difficult to Manage Large-Scale Deployments → Managing thousands of containers requires orchestration tools like Kubernetes.
❌ Limited Cross-Platform Compatibility → Containers are OS-dependent (e.g., a container built on Windows won’t run on Linux without modification).
❌ OS Dependency for Development & Testing → Works best when the development and testing environments use the same OS; otherwise, VMs may be required.
