IBM Bluemix supports various programming languages, such as Java, Node.js, PHP and Python and can be extended to support other languages. The Bluemix platform also includes middleware services, and automatically provisions new instances of those services. Developers can also scale their applications in Bluemix as workload demands change.
Bluemix provides access to other IBM cloud tools and services, such as those for data analytics and security. Developers can also use the IBM Bluemix Catalog to access services for the internet of things, IBM Watson and more.
- Public: A public cloud environment in which applications can access over 100 pre-built services from both IBM and third-party vendors. Developers can choose to deploy their applications in one or multiple Bluemix geographical regions. Deploying applications in multiple regions can help reduce latency and ensure availability; if one Bluemix region goes down, applications can continue to run in other regions.
- Dedicated: A single-tenant, private cloud environment available in over 25 IBM data centers across the globe. Developers connect to the environment using a direct network connection or virtual private network (VPN), and IBM manages the platform.
- IBM Bluemix Local: An IBM Bluemix instance that an organization deploys in its own data center, behind a firewall.
