Learn how to Migrate to Serverless and Make it Work Post-Transition. Migrating to serverless? We’ll be taking you through the steps and what to bear in mind in each stage of migrating to serverless – from preparation to migration and post-transition.
In this article, we’ll be taking you through the steps and what to bear in mind in each stage of migrating to serverless – from preparation to migration and post-transition.
To understand more easily the wider context of migrating legacy systems into a serverless form, we should first understand the cloud spectrum. This spectrum ranges from on-premises workloads to virtual machines, containers, and cloud functions. Serverless typically falls within the cloud functions area, as function as a service (FaaS), but now it’s an umbrella term growing to include back-end as a service (BaaS), such as fully managed databases.
The first thing when looking at _**_legacy transitions_ is _understanding where you are on the cloud spectrum**.
Despite being four or five years old, we are starting to get into a cycle where even serverless apps are becoming legacy systems as well. Anybody that writes Node.js knows that if you make no updates for two years, you’re going to have dependencies breaking all over the place.
The next question to ask is: does your team already have serverless experience?
There are two different routes here:
Yes – We already have serverless experience, we already have cloud experience. In this case, you need to identify the key team members who can help drive and evangelize the serverless migration, including training, pattern development, and so on. The engineering hours involved in the transition can all be streamlined by having the patterns, the documentation and the training.
No – If you don’t have that serverless or cloud experience internally, you would benefit from finding a consulting partner that specializes in serverless migrations (such as Serverless Guru or Theodo) or serverless adoption to help retrain and retool existing employees and help them grow.
