The Paths Forward In Container Portability: Part2: Code Portability Today, we discussed how there are no regression tests, there is no complete interface standard, there is definitely pain ahead if we think we can use today’s container images (level 3B) on tomorrow’s container hosts (level 3A), 10 years from now. So, what’s the solution? With
Code Portability Today In Container Portability: Part 1: A Brief History in Code Portability, we explored the genesis of code portability and visited structured computer organization to highlight the six commonly found levels in modern computing. Revisiting the six layers – nobody debates the portability of the upper two layers – Application Programmers know that C
Background As legacy applications are redesigned for the cloud, they are converted to run in a stateless manner. In newly designed applications, data flows between application code, messaging infrastructure, caches and databases seamlessly even during individual node failures of any one subsystem. When an active node fails, a new one is instantiated and placed back
