Heroku is one of the first cloud platforms operating as a Platform as a Service (PaaS). Its functioning is based on containers used to host a web application in a serverless service. Initially based on the Ruby programming language, but today it also supports Node. js, Java, PHP, Python, Go, Scala or Clojure. It allows fast and relatively simple construction and management, as wel
l as automatic scaling of modern applications without having to deal with infrastructure and server configuration. During compilation, language and system stacks are continuously updated and monitored, preventing conflicts and ensuring that the application is ready to run.
Developers creating web applications with Heroku implement them using popular tools like Git Hub or Continous Integration. The platform has a user experience-focused management panel that provides transparency and easy monitoring of application performance. Also, the tool allows integration and expansion of the entire application with new functionality offered through related add-ons - Redis Heroku, Postgres and Apache Kafka on Heroku. The platform prioritizes the security of data transferred by developers, so it focuses around ISO, HIPAA or PCI compliance, and regular audits are conducted over it.
Heroku also aims to relieve developers' workloads and help solve the most common problems. It is equipped with tools for automatic error notifications and scaling applications if tasks exceed user-specified time thresholds.
