Several organizations rely on monolithic applications developed 10-20 years ago using outdated technologies, causing security and compliance issues. In addition, these legacy applications and architectures restrict businesses from scaling, impair agility and hurt customer experience.
As technology organizations embark on their cloud transformation journey, different paths could be pursued with varying timelines of implementation and TCO. These range from re-hosting (lift-and-shift), re-platforming, re-factoring to take advantage of containers and re-writing using cloud-native technologies. For example, re-host is the quickest and cheapest way of cloud adoption with very high TCO. On the other hand, cloud re-write is the most expensive and time-consuming option for implementation, delivering the most benefits of cloud, including the lowest TCO — other options like re-factoring and re-platforming fall in between.
There are costs and benefits of going cloud platform-specific vs. staying cloud-agnostic.
Choosing the right path is not a trivial task and has near-term and long-term implications. Cloud workload assessment and analysis are critical steps to decide on the right path to cloud, considering the future business and technical requirements.
