Designed to implement and support industry best practices for Enterprise Architecture and Cloud deployment, WSO2 Middleware Platforms and Platform-as-a-Service (PaaS) give customers the best platform to write highly-available and scalable applications.

WSO2 is the only company that can provide you with a complete middleware platform that can be run on-premise, in the private cloud, and is also available as a Service (PaaS). Enterprise-grade and cloud-scale middleware is now accessible to all.

Java PaaS
On-premise on physical or virtualized environments. Cloud-native (multi-tenant and metered), can be deployed as a private or public PaaS. Public and Java PaaS operated by WSO2.
Includes a full suite of products including WSO2 ESB, WSO2 Governance Registry and more – everything you need to develop enterprise apps and business processes; start with what you need and easily add new capabilities. Enterprises and ISVs get the full benefits of leading-edge cloud infrastructures – going from just using VMs to quickly building higher level PaaS or multi-tenant, self-service and elastic SaaS applications. SMBs get instant access to powerful enterprise middleware services.
In production at 100+ Fortune 1000 enterprises, handling over 1 Billion messages per day at eBay. Business units, regional offices, SMBs and tenants can self-provision and use PaaS APIs (ESB-as-a-Service, Governance-as-a-Service and more) and SaaS Apps. Pay for what you use, simple monthly billing and SLAs.
Common Code Base:
  • Complete middleware stack – application server, ESB, governance, identity, BPM, BAM, portal…
  • OSGi-based componentized platform
  • 100% open source and standards-based

  • To completely protect from lock-in, all WSO2 platform technology is completely Open Source and based on Open Standards.
  • The WSO2 middleware platform offers a full range of core services: application server, enterprise service bus (ESB), governance registry and repository, identity and access management, business process management (BPM), business activity monitor (BAM), portal server and more.
  • Developers can build distributed and composite applications – Web apps, Java services, BPEL flows, server-side JavaScript, rules, complex event processing (CEP) and legacy integrations – with more speed, flexibility and ROI.

OSGi-based Componentized Architecture & Consistent User Experience

Unlike bloated, proprietary middleware platforms cobbled together from acquired technologies, WSO2’s lean , OSGi-based componentized platforms share a common code base and repository. Start with just the functionality you need – an ESB, identity management solution or governance registry – and grow the system over time. All products – the WSO2 Application Server, WSO2 Enterprise Service Bus (WSO2 ESB), WSO2 Governance Registry and more – are configured and managed in a common, consistent manner – making it easy to add new functionality.

Open & Infinitely Flexible

Unlike proprietary middleware stacks and closed public platforms, the 100% open source and standards-based WSO2 platforms and Java PaaS give developers maximum protection against lock-in. Enterprises, ISVs and SaaS providers have the freedom and flexibility to respond to changing business requirements by migrating apps and data across on-premise and cloud infrastructures and from one cloud provider to another.

The platform interoperates with existing and new purchases of standards-based components, integrates with a wide variety of legacy and packaged apps, and enables easy access to databases and file systems. Developers can extend the platform, customize code and use any programming model they like. Instead of forcing you to adapt your systems to the middleware platform, WSO2 platforms adjust to your environment.
