I work for a company that does about 100M revenue per year. Run everything on prem, we did the numbers if we moved to AWS, it was almost 10 X of our current spend. Again , depends on your business, ours is complex and compute intensive.
But at scale, on-prem always wins.
Different numbers, but almost the exact same 10x spend difference moving all to AWS. We are data/compute heavy with low bandwidth use. We still use Lambda for bursty traffic if it works for the use case.
I work for a 100M rev/year company as well and we used to run our ecommerce site on-prem as well. We knew of the increase to cost for moving our infrastructure to AWS but we're happy to bite that bullet for the vast array of services we now leverage in AWS as well as faster site response times and increased reliability.
