Cloud Native applications are a combination of existing and new software development patterns. The existing patterns are software automation (infrastructure and systems), API integrations, and services oriented architectures.

Cloud Native Applications consist of microservices architecture, containerized services,and distributed management and orchestration.

• Ensure the desired number of Pods are running and available

• Automatically replaces Pods that fail or are evicted from their nodes

• Automatically associates new Pods with the storage resource, resource requests

#vFORUMAU

Trying to run these in Kubernetes?

• Databases

• Postgres, MongoDB, MySQL, MariaDB, Redis, Cassandra

• Search, Analytics, Messaging

• ElasticSearch, LogStash, Kafka, RabbitMQ

• Content Management

• Wordpress, Joomla, Drupal, SugarCRM

• Service Discovery

• Consul, Zookeeper, etcd

• Continuous Integration and Delivery

• Jenkins, GitLab, SonarQube, Selenium, Nexus

• Custom Applications
