WSO2 Stratos - 100% Open Source Cloud Platform for Enterprise Applications

WSO2 Stratos

WSO2 Stratos is the most complete, enterprise-grade cloud solution. Offering an open Platform as a Service (PaaS), it supports more core services than any other available PaaS today. WSO2 Stratos is the perfect answer to enterprises who seek to extend the flexibility and innovation achieved from implementing heterogeneous environments on-premises, into the cloud.

The open nature of WSO2 Stratos makes it the perfect environment for hosting companies, ISVs and System Integrators to build and customize Industry-specific PaaS and Software as a Service (SaaS) platforms for vertical markets; for example, creating a Mobile PaaS for telecom companies.

WSO2 Stratos offers a polyglot PaaS and polyglot programming experience, delivering the ability to mix-and-match application platform capabilities into an customized application Platform as a Service (aPaaS).

At the core of WSO2 Stratos is the WSO2 Stratos PaaS Foundation, which provides cloud-native capabilities, such as multi-tenancy, elastic scaling, self-service provisioning, metering, billing, and resource pooling, among others.

Running on top of the Foundation are pre-integrated, fully multi-tenant WSO2 Carbon middleware products that deliver a range of PaaS services. These include WSO2 Enterprise Service Bus (WSO2 ESB), WSO2 API Manager, WSO2 Application Server, WSO2 Governance Registry, WSO2 Business Activity Monitor, WSO2 Business Process Server, WSO2 Business Rules Server, WSO2 Identity Server, WSO2 Complex Event Processor, and WSO2 Message Broker.

Similarly via the WSO2 Stratos cartridge architecture, you can easily plug in any runtime as a service. Traditional, non-cloud-aware application platform containers, such as PHP and MySQL, can be extended into a multi-tenant cloud deployment.
