A container is an isolated unit of software running on top of an operating system. Containers are getting popular among startups because containerized applications are portable, have built-in scalability and fault tolerance, are more secure, and promote faster development cycles. That’s why startups prefer containers for new application development to gain a business advantage over competitors who are still using VMs for application deployment and packaging.

We have completely updated our migration guide from Heroku to AWS. This guide covers everything needed to migrate from Heroku to AWS a complete stack of applications and databases.

CI/CD is now an inevitable need of every modern application. Many startup companies adopt CI/CD with a good cloud vendor. Still, they do not follow the guidelines needed for successful deployment, and even if they do that, they find difficulty scaling the application. Here in this article, we will go through a comprehensive checklist to help you perform stable and successful production deployments on AWS.

Imagine this: You are an engineer at a startup. You are responsible for keeping all the applications running smoothly and safely in production. At first, you have things under control, but soon enough things start getting more complex.
