# Scaling Solution

SolRazr is built to be fast, highly available and scalable right from the beginning. Here are some of the key considerations we had while building SolRazr’s application.\
\
Here is the overview of the architecture of our application.

**Highly available:**\
Application is behind load balancer that auto scales servers based on the load. We have run load tests to make sure we are always available.\
\
**Custom RPC endpoints:**\
We have a set of custom RPC endpoints that exclusively serve only SolRazr’s requests. This makes sure SolRazr is available even when Solana mainnet RPC endpoints are overwhelmed.\
\
**Fast content delivery:**\
We have also enabled cloud CDN to make sure the application is blazing fast\
\
**Secure connection:**\
Content on SolRazr is always delivered securely via HTTPS. Also, every asset is behind VPC and is inaccessible for unwanted actors.
