Deploy ESB as a Service

In today’s business environment, increasing agility and lowering cost is a business imperative.  Forward thinking development teams are deploying shared services (e.g. ESB-as-a-Service) instead of traditional middleware silos.  Our total cost of ownership calculation indicates organizations can save significant software subscription cost, operations management effort, and infrastructure expense when deploying multi-tenant, shared container based application platform middleware services.

Many WSO2 clients run several WSO2 Enterprise Service Bus instances in production today, and we encourage our clients to evaluate how implementing ESBs within a Cloud Platform-as-a-Service environment reduces time to market and decreases ownership cost.

Moving eGovernment to Cloud

For any Government organization needing to do more with less, eGovernment is the answer. eGovernment solutions cost effectively deliver information and enable transactions among citizens residing within a local geography.  An eGovernment solution may also link various governmental groups supporting constituents. However, the role of eGovernment has been traditionally limited by the inherent cost and complexity of developing, integrating, and managing traditional server-based systems. To overcome these hurdles, government agencies are looking to cloud solutions as a way to radically scale service delivery while simultaneously minimizing the expenses related to IT infrastructure, application development and deployment, and operations. WSO2 has published a white paper examining demands faced by government agencies and how the cloud-native WSO2 eGovernment solution provides a powerful, highly flexible, and extensible platform that addressing eGovernment requirements in a cost effective manner.

Cloud Native PaaS or Cloud Washed PaaS

With mainstream vendors (e.g. RedHat OpenShift, IBM Cloud Application Services, Oracle Public Cloud, ActiveState Stackato) promoting quickly pushing bits into the Cloud, smart development teams have established a clear Cloud Platform comparison criteria and a process to determine if the run-time PaaS will exhibit cloud characteristics and offer a Cloud Native instead of a Cloud Washed experience.

Changing the Cloud Developer Experience; User, Workspace, API, Channel, and Service

PaaS and DevOps tooling is an opportunity to raise infrastructure abstraction.  DevOps tooling integrated with PaaS should shield developers from hardware infrastructure concerns and expose business entities.  The Cloud washed PaaS environments commonly do not shield application developers, integrators, and architects from infrastructure details (i.e. memory configuration, location, number of machine instances). While short-term benefit is derived by ‘quickly pushing bits into the Cloud’, the design and development experience remains the same.

Cloud Native PaaS realizes Cloud Characteristics

Cloud Native PaaS run-time environments should significantly exhibit essential Cloud characteristics. The NIST Draft – Cloud Computing Synopsis and Recommendations defines Cloud characteristics as:

  •  On-demand self-service
  •  Broad network access
  • Resource pooling
  • Rapid elasticity
  • Measured service

How do these characteristics influence run-time behavior and determine whether PaaS offerings are cloud washed or cloud native?

Cloud languages and me-too vendors

Sinclair @sschuller has triggered a lively debate over at Cloud U on Linkedin.   Sinclair’s blog post questions why PaaS providers “want to add as many languages as possible as quickly as possible. ”   Sinclair questions the business value obtained by polyglot language support and whether development teams will see through the hype and “walk away disenfranchised.”

Searching for Cloud Architecture….

Does Platform as a Service (PaaS) exhibit a distinct cloud architecture model?  What specific cloud reference architecture components are required?

The WSO2 vision of Cloud-aware applications and WSO2 Cloud Reference Architecture is found in a blog post here.  Read this blog post to review cloud architecture alternatives.

Will IT culture kill Cloud?

The doctors are circling.   My Gartner colleague Lydia Leong has an interesting Cloud prescription, ‘to become like a cloud provider, fire everyone here,’  and industry watchers are picking up the message.

In her post, Lydia describes a Cloud conversation with corporate IT stakeholders and diagnosing:

“If you’re going to operate like a cloud provider, you will need to be willing to fire almost everyone in this room.”

Ghost in the machine

What PaaS capabilities and components are required to migrate your application into the Cloud?  WSO2 announced the  WSO2 Stratos cloud middleware platform version 1.5.2 release.  Besides enhancements to 12 service components (i.e. application server, data service platform, enterprise service bus, identity service, governance service, gadgets, business activity monitoring, business process, business rules, mashups, message broker, complex event processing),  core platform enhancements include an innovative service-aware load balancer and ghost deployer.
