Welcome to the first article in our AWS Migration Considerations Series. You can find the start of the series here.
Digital system migrations have occurred since the dawn of digital services.
Every digital service that has endured for more than a couple of years has had a migration of some type. They are called many things, but servers, storage, and even data centres have been swapped out to new solutions over time.
A full data centre (to classical data centre) was often timed to be before the expiry of both existing IT equipment warranty expiry, and the lease expiry or renewal period. The process would start a year prior from the proposed end-date, with fresh equipment being reviewed and priced. Data centre visits would then be undertaken to inspect the new building and a standard set of mundane checks would be done:
And then a synchronised dance would happen:
You will note that we started paying for the new data centre, and the kit, well before the cut over. Even without a data centre change, there is the risk of doing something like a Storage Access Network (SAN) migration:
All that work required resources. The cost of this as well as the cost of having new equipment while not yet using it, and old equipment that is no longer in use but not yet sold, represents a massive cost of operation.
You will find that because you have replaced a SAN it does not make people use your service or buy your product anymore; it is not a key differentiator in your market. We are doing this effort to maintain the technical environment.
These migrations within deployed solutions are continuous. Operating Systems, Hardware, Programming languages, Data Centres, Telcos & Internet Service Providers, DNS registries, CDN operators, database versions; the list is endless for the maintenance that is often overlooked or accumulating as Technical debt.
