Anyone who has worked with databases in the past has probably encountered the CAP theorem. The CAP theorem states that your distributed database can have any 2 of Consistency, Availability and Partition Tolerance. Relational Databases are traditionally often "CP" forgoing availability and NoSQL databases may be "AP" sacrificing consistency for the sake of availability.
Fast forward a few years and cloud databases make this not quite so black and white. PACELC was introduced to factor in latency and provides 4 possible database configurations.
When building a data architecture (particularly for multi-tenant applications) there are a few more considerations that go into your decision around which data store(s) to pick and how to configure those data stores.
We put together a loose framework to guide this decision called "S.C.A.L.E".
S.C.A.L.E stands for Scalability, Consistency, Availability, Latency and Evolution and exists as a rubric to decide which data technologies to adopt for your applications requirements:
TenetQuestions
S = Scalability“Are you able to use computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes.”
C = Consistency“How do you know that your data changes have been made successfully, and will persist”?
A = Availability“The ability of a system to recover from infrastructure or service failures, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfiguration or transient network issues.”
L = Latency“Are your tenants happy (in terms of performance). How do you know? If not, what can you do about it?
E = Evolution“Will your SaaS application survive the journey from Client/Server through APIs, Microservices to the future”?
Based on the tenets of this framework, we're pleased to share a new series of on-demand videos available discussing some of the key concepts around building data architectures for SaaS applications on AWS.
Check out the first 4 here on YouTube (and be sure to subscribe so you know when the next batch get added!).
The first 4 episodes cover:
Episode 1: Introduction - Grant walks us through S.C.A.L.E and what to expect from the series
Episode 2: Scaling relational databases for SaaS - I take a dive into the vertical and horizontal scaling strategies for relational databases
Episode 3 - Why Consistency matters in relational databases - Venkatesh explores the concept of consistency and how this translates into modern data architectures
Episode 4 - Tenant backup and restore - Extracting individual tenants for backup and restore purposes is a common ask of SaaS applications. Dave shows us how!
I hope you enjoy the first 4 episodes. Please let us know what topics you'd like to see next and be sure to subscribe to hear about the next 4 soon!
