On the future of cloud services and BYOC — Jack Vanlightly

This great convenience and productivity booster also brings a whole new form of lock-in. Hybrid/multi-cloud setups, which seem to attract many architects' attention these days, are a good example of the kind of things you'll have to think of when dealing with lock-in. Let's say you have an application that you'd like to deploy to the cloud. Easy en... See more

• Effort : This is the additional work to be done in terms of person-hours. If we opt to deploy in containers on top of Kubernetes in order to reduce cloud provider lock-in, this item would include the effort to learn a new tool, write Docker files, configure Kubernetes, etc.


• Expense : This is the additional cash expense, e.g. for product licenses,

For example, many architects favor not being locked into a database vendor or cloud provider. However, how likely is a switch really? Maybe 5%, or even lower? How much will it cost you to bring that switching cost down from let's say $50,000 (for a semi-manual migration) to near zero? Likely a lot more than the $2,500 ($50,000 x 5%) you can expect ...

Architecture lock-in : You may also be locked into a specific kind of architecture. For example. when you use Kubernetes extensively, you are likely building small-ish services that expose APIs and can be deployed as containers. If you want to migrate to a serverless architecture, you'll want to change the granularity of your services closer to si
