Part 1: How does the SuperTokens managed service work and why does it need to change.
\nPart 2: Using multi-tenancy to cut our AWS infra costs by by more than 50%
\nIn this part we will go over SuperTokens Multi-tenancy feature and how it evolved our deployment cycle to cut our AWS billing by 50%.
\nHere’s what we covered in our last post:
\nAs mentioned in Part 1, “We saw multi-tenancy as an opportunity to optimize the utilization of our EC2 instances by consolidating our core instances. This would cut down our costs while also providing the expected performance”… But what does that mean? Let’s break it down. Multi-tenancy is a feature, typically used by B2B SaaS companies to allow multiple organizations to sign up to their SaaS app, with the ability for each organization to have their own login methods or SSO configurations. Additionally, user pools can also be segmented. Here’s how it helped us.
\nWith multi-tenancy, we re-architected the way we host and manage our users. Initially, whenever a user signed up and created an app with SuperTokens, it would trigger the following flow:
\nIn this process, each development and production SuperTokens core ran in it’s own separate EC2 instances. With Multi-tenancy we now treat all SuperTokens customers as tenants. This means that we could now host multiple users on a single SuperTokens instance. Our deployment process now looks like this:
\nWell, the biggest difference post this change is the cost savings.
\nHere’s a bill for the month of July before the multi-tenancy changes kicked-in:
\nWhen compared, its 54% down
\nAnother improvement was app startup time. In the new architecture, creating a new user is as simple as creating a new tenant. When compared to the old process, the new architecture is about 94% faster and new apps can be created in seconds.
\nMulti-tenancy with SuperTokens is a powerful feature that enables businesses to create unique authentication flows for their customers, segment users into unique user pools and automatically create new tenants. For SuperTokens, multi-tenancy allowed us to consolidate our user applications to save on resources, but, your use case maybe very different.
