A Case for the Service Orchestrator:
Enabling Ubiquitous Ecosystem Performance
(Why ACID and BASE Transaction Consistency Will Not Be Enough)

Mark Skilton

Mark Skilton

Not "one size fits all". A common misconception in cloud computing is the ability to use select and go IT services at will as if they are Lego bricks that plug together like a model set of processes. Nothing could be further from the truth in practice. From a consumer perspective, a cloud may involve this user experience of self-service usability on-demand, and the purchasing contracts, terms and conditions may define and constrain the use of these services. But from the provider perspective, the technical service architecture that enables consistency in performance availability and security, let alone if this then becomes an integrated solution, is not trivial. Cloud computing is a distributed architecture connecting different devices, networks and computing components together with different management and control systems to provide software, hardware and content management...


Hybrid Cloud Solutions: Combining On-Premise and Cloud Components to Build Reliable, Secure, and Scalable Applications

Dan Rosanova

Dan Rosanova

Cloud-based solutions are increasingly gaining traction, although technical, regulatory and attitudinal reasons are preventing many systems from transitioning to the cloud. Combining existing on-premise solutions with cloud-based components will increase flexibility and reach, while improving reliability and security. This article explores hybrid cloud scenarios that combine cloud with traditional delivery methods; these include cloud-based front-ends, secure service tunneling, elastic computing and cloud-based disaster recovery. Cloud is a force to be reckoned with-its technology and architecture are steadily maturing and becoming increasingly more stable. The market is healthy and expanding, guided by industry experts with the influence and sophistication to successfully man the changeover. There are, however, several major...


Governing Shared Services On-Premise and in the Cloud (Video)

Thomas Erl

Thomas Erl

Shared services are high-value IT assets that now have the potential to reap greater long-term returns by taking advantage of the vast resources offered by cloud platforms. They can be more robust, scalable, and more rapidly configurable and therefore can directly realize concrete levels of organizational agility in support of business automation goals. Charting a strategic path for shared services requires establishing governance controls as early on as the modeling stage and, from thereon, never looking back. By referencing techniques from the acclaimed book "SOA Governance", this session highlights some of the key considerations pertaining to the governance of shared and reusable services with an emphasis of how governance approaches can differ with the utilization of cloud computing.


Semantics Enabling Next Generation SOA – Part II

Johan Kumps

Johan Kumps

This is the second article in a two-part article series. Read the first part of this article here. In some cases, as the consumer requirements shift towards more complex functionality, they cannot be fulfilled by a simple atomic service. This shortcoming can be handled by service composition, that is the appropriate combination of certain atomic services in order to achieve a complex goal. There are several kinds of service composition. Traditionally a manual approach is used where an analyst tells the system which services should be executed in which sequence. Processes are defined using a process execution language like BPEL. This invocation plan is pretty fixed at design time although business rule engines can be used to route through the plan based on parameters only known at runtime. The problem...


EAI and EDI in the Cloud: Prospects of Azure Service Bus
EAI & EDI – Part II

Manfred Steyer

Manfred Steyer

This is the second article in a two-part series that discusses how in the future, the EAI features of Azure Service Bus will offer the transformation and routing of messages to integrated systems on a pay-per-use basis while maintaining its usual high availability. Moreover, standards like EDIFACT and X12 will also be supported in the same way as the integration into local systems via relaying. To read the first part of this article series, click here (link). To enrich data in a bridge, actions which extract values from the message and subsequently map them to other values can be configured. These actions are to be performed in the framework of the Property Definitions feature which is offered by the enrich stages of a bridge. So-called lookup providers are used for the mapping of values. The present CTP only contains...


New Cloud Computing Design Patterns at CloudPatterns.org

http://www.cloudpatterns.org/

Descriptions of over 50 cloud computing design patterns and 28 technology mechanisms are being published to the new CloudPatterns.org Website. This community site is dedicated to establishing and growing the official cloud computing design patterns catalog. Rough draft versions of the initial set of patterns have been made available now, with further revisions to be carried out over the next few days. Additional patterns will be published throughout the upcoming weeks. This site allows for the submission of candidate patterns that can be published for public review and commentary, and potential consideration for inclusion in the master patterns catalog.
