These standards alone, however, did not address the problem of transmitting messages in a secure and reliable way. Indeed, businesses do not want to send critical or sensitive data over the public Internet in a way that cannot be secured or where there are no guarantees that requests are completed. WSE implements:. The key benefit of WSE is that it allows the quick implementation of these specifications and relieves the developer from having to code the low-level XML details that would otherwise be required to implement them.

The next iteration of. Advanced Web services support in Indigo will provide secure, reliable, and transacted messaging along with interoperability. According to Microsoft, Indigo will deliver a programming model and implementation based on service-oriented concepts. Net provide capabilities to achieve this goal but they approach this in different ways.

Microsoft has embraced the SOA by the introduction of their. NET initiative. Microsoft describes. NET as "an open language platform for enterprise and Web development". SOA is an architecture which evolved from the distributed and the components architectures and has become the new one to solve complex problems around the enterprise environment. Microsoft is entering in this new area and is actively working in specifications, products and interoperability efforts.

It is recommended to follow the development in this new approach henceforth. View All. Service-Oriented Architecture and Microsoft. John Charles Olamendy Updated date Oct 13, What is Microsoft. NET consists of:. NET Framework as the core component. Developer Tools, such as Microsoft Visual Studio. Client software, such as Windows XP, Windows CE, and Microsoft Office XP, that helps developers deliver a deep and compelling user experience across a family of devices and existing products.

From a more developer perspective, the concepts behind Microsoft. NET are: It is a new environment for developing and running applications. It provides the framework for an Internet-centric industry standard that makes it possible to implement a service-oriented architecture by tying together applications, information, and data sources using Web Services.

It enables software to become platform- and device-independent. What is Service-Oriented Architecture? The principles of SOA require that the services should: Have behavior that is clearly defined by a published interface contract.

Have network addressable interfaces or endpoints. Be dynamically discoverable and usable. Emphasize interoperability. SOA deployment. The steps involved can be grouped into three phases: Exposing the existing systems as core services.

Building business services from these core services. Using the business services to achieve business process modeling. Service-Oriented Architecture and Web Services. Participated in recruiting and training new developers for project needs. Joined scrum review sessions every week with the project manager and customer to update them with status, progress and issues. Set up a network load-balancing system to improve the availability and performance of web-based applications that could serve thousands of concurrent users.

Team Lead - Designed and built a dynamic form-based application using C and XML which can easily be extended and modified to meet UI and UX requirements without having to change the codes.

Widely applied asynchronous communications between end applications and services to give users the best experiences. Led a small team of six developers to work mostly on end applications. Coordinated with the services and databases team to ensure development priorities and planned are aligned together efficiently.

Worked together with the QA team and customers to evaluate requirements, to review and continuously improve the application. Teaching Assistant - Developed and created a digital library for the faculty using Greenstone open-source software. Assisted in giving lectures to students in various areas of computer and information systems.

Chris Marisic Chris Marisic I think the reference to the ". See this link: microsoft. For direct connections, the service needs to also open up port on its machine something that may involve a one-time user prompt.

Hybrid, the communication starts as a relay via the relay service. If direct connection between the client and the service is possible, the relay service will promote it to direct connection.

Otherwise, it will remain as relayed. The relay service can promote to direct even as the message is being relayed without any loss of data. The hybrid mode should be the preferred connection mode over the TCP relay binding. However, it has one drawback: both the direct and the hybrid modes require the binding to use Message security, and as you will see in the next installment of this column, Message security requires additional configuration and setup.

And while these are simple steps, they do preclude hybrid as a working option by default. I mentioned it already, but it's worth highlighting the fact the TCP relay binding supports duplex callbacks through the relay. Setting up the duplex calls and accessing the callback reference is identical to the regular TCP binding.

Presently, the TCP relay binding is the only relay binding that supports duplex callbacks see Figure 6. Like the regular WS binding it uses text encoding by default, and when Message security or reliable messaging is employed, it will maintain the transport session over the relay.

The scheme for the address is either http or https. As far as capabilities and use, the WS relay binding is just like the TCP relay binding, except it supports only relayed connection. You should use this binding either when the TCP ports used by the TCP relay binding are blocked or when you have an explicit need to interoperate. The one-way relay binding allows the client to send its message to a buffer maintained at the relay service, rather than the service itself, and later have the relay service try to deliver the message to the service.

To control the load on the. No reply from the service is possible and in fact, the one-way relay binding verifies that all operations on the endpoint's contract are defined as one-way operations. In the case of both the TCP and the WS relay bindings, when the client calls the relay service, the service itself must be listening or the client will encounter an EndpointNotFoundExcpetion exception, just as with non-relayed WCF this is the case even when the operations are defined as one-way.

In the case of the one-way relay binding, the client can issue the call regardless of the presence of the service, and there may not even be a service listening at all. As a result, you should choose the one-way relay binding whenever the service's state is unknown. The downside is that the client has no guarantee of delivery of its messages, nor is there any guarantee of the order of the calls dispatched to the service.

In addition, because of the inherent disconnected nature of the one-way relay binding, there is never a transport session. Just as with the TCP and the WS relay binding, there can be only one service monitoring the relayed address, while there could be any number of clients calling that service.

For the schema, the one-way relay always uses sb:. It allows any number of services to monitor the same URI in the relay service. Once a client sends a message to the relay, all monitoring services receive it. Given the fact there is no limitation on the number of clients, this in effect provides for N:M communication where both N and M can be any natural number including zero, similar to UDP multicast.

Since the specialization is on the service side, the client can use either the one-way relay binding or the event relay binding while the services must use the event relay binding.

In addition, unlike any other relay binding, you can also have services listening concurrently on nested URIs. As with the one-way relay binding, there is no guarantee of order of messages or of delivery itself. By far, the canonical case for using the event relay binding is event publishing and subscription, as show in Figure 7. The clients, now called publishers, call the relay service now acting as an events hub, delivering the events to any number of services, now called subscribers.

In reality, the events relay binding is indented to provide only a lightweight, ready-made, cloud-assisted event distribution solution for delivering events to running services. The more powerful features of administrative support for adding and removing subscribers, events filtering, and events queuing to enable both queued publishers and queued subscribers all require the use of queues and routers, which I will discuss in an upcoming column.

If you merely want to publish events to running subscribers over the relay service, then treating the relay service as your events hub will suffice.
