At Squared Paper we employ a number of open source/freely available technologies. We believe this brings us and you many benefits, including that there is a large amount of documentation and regular updates available. Not to mention this means our software is cheaper to you.

Java

Java is a general-purpose, class-based, orientated computer programming language. Using Java allows us to develop multi-threaded cross-platform compatible applications and services.

TypeScript

TypeScript is an open source programming language developed and maintained by Microsoft. It is a typed superset of JavaScript that compiles to plain JavaScript. Using TypeScript in all of our JavaScript based applications and services means we can implement best practice and object-orientated modules.

Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment. Node.js has an event-driven architecture capable of asynchronous I/O. Using Node.js allows to quickly and efficiently write and deploy both server side and client side applications, sometimes making use of modules which have been contributed by the JavaScript community via npm.

npm

npm is the package manager for Node.js. The npm registry contains hundreds of thousands of modules for Node.js contributed by the JavaScript community. Using npm allows us to use some pre-existing code as the basis for some of our modules, giving us a head start and getting your software to you more quickly.

PostgresSQL

PostgreSQL is an object-relational database (ORDBMS). We use PostgresSQL when we need to persist data in a relational database format for later use.

Elasticsearch

Elasticsearch is primarily a search engine. At Squared Paper we use it to store our JSON configuration data, which it is very well suited to. It is fast, simple to use, reliable and easy to cluster and scale. We also use Elasticsearch for some customers to store log files for later interrogation and analysis.

Apache Cassandra

Apache Cassandra is a distributed database management system which can handle large amounts of data across many servers. It provides high availability with no single point of failure. We use Apache Cassandra as part of Busby Big Data.

Centos

Centos, based on Red Hat Enterprise Linux, is an operating system widely used for servers. It is reliable and updated regularly. We recommend Centos to customers when specifying operating environments for Busby systems.

RabbitMQ

RabbitMQ is an open source message broker software. Written in Erlang, it implements the Advanced Message Queuing Protocol. RabbitMQ is fast, reliable and easily clustered. We deploy Busby Core using RabbitMQ as the messaging layer.
