Serverless vs Containers

Serverless

Serverless computing in Cloud Computing technology is the concept where the computing resources are completely handled in BTS (Behind the Scenes), where the programmer or developer mainly focuses on writing the code logic to handle specific events. This code is wrapped as a serverless function or method and invoked or triggered by the serverless runtime as many times as necessary to fulfill the incoming requests. Serverless works on the architecture of Function as a Service (FaaS). The deployment model used in Serverless is small, stateless functions that are executed in response to specific events. Resource Management is completely managed by the cloud provider dynamically. The pay-as-you-go cost model is adapted to Serverless computing....

Containers

Containers in Cloud Computing are the lightweight and portable units of software that wrap the applications and their associated dependencies together. Containers allow the software to run efficiently and consistently across various computing platforms and environments, like development, staging, testing, building, and production. Containers are purely based on the technology of containerization, with Docker being one of the most used containerization platforms. Containers provide a fixed amount of resources to the application with the container. Developers need to externally specify these resource limits during containerization. Docker is the best tool for containers....

Best Practices for Choosing Between Serverless and Containers

Choosing between Serverless and Containers relies on different constraints and factors like Application requirements, development team expertise, scalability needs and many more. Below are some of the best practices that can help to choose between Serverless and Containers:...

Serverless vs Containers

Parameter Serverless Containers Architecture Follows Function as a Service (FaaS) Application and Dependencies are packaged together Cold Start Slight latency is seen during the first execution. Faster startup times is been seen as compared to Serverless. Cost Model The Pay-as-you-go Cost model is been adapted. Constant cost is been adopted in Containers. Scaling Automatic Scaling is used based on demand. Manual or Automatic scaling of containers has been used. Portability Limited, potential Vendor Lock-in. High Portability across container platforms and runtimes. Use Cases Small Tasks, Microservices, Event-driven apps. Complex workload applications, steady workloads. DevOps Overhead Minimal management and infrastructure concerns are seen in Serverless. Additional Management complexity is needed in Containers....

Conclusion

In conclusion, choosing and using between Serverless and Containers can be a critical decision that is dependable on various factors. For making the right choice between these two technologies, it is important to initially understand the application requirements, ita cost requirements, and many other factors. By analyzing all these aspects and aligning them with our development goals, we can determine whether the requirement is fulfilled by Serverless or Containers....
