Automation on Cloud Migrations
Pedro Faria, Tomás Simões, Yan Qianmin · 2024
While it looks obvious that moving from on premise infrastructures to cloud infrastructures is the only way all companies should do, the process and confidence on the systems seem slower than we expect once we know how these systems work. Data centre cloud digitalisation process started with uploading simple documents but now, it’s much more special because cloud infrastructures are far more secure and allow us to scale with no physical upfront costs. All seems obvious but the resistance occurs on the process itself. Cloud providers offer solutions such as serverLess solutions which don’t take much time to make the migration, but still the process is sometimes unknown to cloud migration team. This current paper has the intention to show, how easy migrations of software can be with the result of a tutorial in AWS Lambda, including testing before deployment and reducing the risk and extra upfront costs over scaling. As a result of this paper, a new term is used and called as Systemless which refers to the automation process of architecture in the cloud, in which it is possible to use Serverless systems and patterns to deploy everything in a few minutes, no matter how complex it is.
