HA in PostgreSQL databases delivers virtually continuous availability, fault tolerance, and disaster recovery. Also, in general terms, a high availability PostgreSQL solution must cover four key areas: Infrastructure: This is the physical or virtual hardware database systems rely on to run. there cannot be high availability.

High availability works through a combination of the following: No single point of failure (SPOF) : You must eliminate any single point of failure in the database environment, including physical or virtual hardware the database system relies on that would cause it to fail. there cannot be high availability. Is Planet Earth Flat?

Consider an example where a company is running multiple virtual machines (VMs) on a cloud provider. Whether you're scaling storage solutions like S3 buckets, compute resources like EKS clusters, or content delivery mechanisms via CDNs, Terraform offers a streamlined approach. ‍For CDNs, redundancy is really important.

Resource consumption & traffic analysis. Lift & Shift is where you basically just move physical or virtual hosts to the cloud – essentially you just run your host on somebody else’s hardware. What is the network traffic going to be between services we migrate and those that have to stay in the current data center?

Technically, we have to split our existing application into microservices virtually. By “virtually” I mean that in general, you don’t need to change your existing application physically: it’s enough to have structure settled in any form even if only on paper. From now on, we’re directing HTTP traffic to our React subfolder.

s web-based applications often encounter database scaling challenges when faced with growth in users, traffic, and data. Behind the scenes, Amazon DynamoDB automatically spreads the data and traffic for a table over a sufficient number of servers to meet the request capacity specified by the customer.
