Cloud gives ESBs a new lease of life

ESBs have become the cornerstone of many SOA deployments, providing a reliable and flexible integration backbone across enterprises. However, the Cloud Computing model has given ESBs a new lease of life as the link between the safe, secure world behind the firewall and the great unknown of the Cloud.

As ESB vendors look for more reasons for users to buy their products, the Cloud model has emerged at just the right time. Companies looking to take advantage of Cloud Computing quickly discover that because of key inhibitors like data location, they are forced to run applications that are spread between the Cloud and the Enterprise. But the idea of hooking up the safe, secure world of the enterprise, hiding behind its firewall, and the Cloud which lies out in the big, wide and potentially hostile world is frightening to many. Step forward the ESB – multi-platform integration with security and flexibility, able to hook up different types of applications and platforms efficiently and securely.

More and more ESB vendors are now jumping on the ‘Cloud ESB’ bandwagon. Cast Iron, now part of IBM, made a great name for itself as the ESB for hooking Salesforce.com with in-house applications; Open Source vendor MuleSource has been quick to point to the advantages of its Mule ESB as a cost-effective route to cloud integration; Fiorano has tied its flag to the Cloud bandwagon too, developing some notable successes. Recently, for instance, Fiorano announced that Switzerland’s Ecole hôtelière de Lausanne (EHL) had adopted the Fiorano Cloud ESB to integrate 70 on-premise applications with its Salesforce.com CRM system.

Over the next few months, we expect to see a growing number of these ‘cloud ESB’ implementations as more companies realize the potential benefits of combining ESBs and Cloud.

IBM acquires Cast Iron

castironI am currently at IBM’s IMPACT show in Las Vegas, where the WebSphere brand gets to flaunt its wares, and of course one of the big stories was IBM’s announcement that is has acquired Cast Iron.

While Cast Iron may only be a small company, the acquisition has major implications. Over the past few years, Cast Iron has established itself as the prime provider of Cloud to Cloud and Cloud to on-premise integration, with a strong position in the growing Cloud ecosystem of suppliers. Cast Iron has partnerships with a huge number of players in the Cloud and application packages spaces, including companies such as  Salesforce.com, SAP and Microsoft, and so IBM is not just getting powerful technology but also in one move it is taking control of the linkage between Cloud and anything else.

On the product front, the killer feature of Cast Iron’s offering is its extensive range of pre-built integration templates covering many of the major Cloud and on-premise environments. So, for example, if an organization wants to link invoice information in its SAP system with the Salesforce.com sales force environment,  then the Cast Iron offering includes prepared templates for the required definitions and configurations. The result is that the integration can be set up in a matter of hours rather than weeks.

So why is this so important? Well, for one, most people have already realized that Cloud usage must work hand-in-hand with on-premise applications, based on such things as security needs and prior investments. On top of this, different clouds will serve different needs. So integration between clouds and applications is going to be a fact of life. IBM’s acquisition leaps it into the forefront of this area, in both technology and partner terms. But there is a more strategic impact of this acquisition too. Noone knows what the future holds, and how the Cloud market will develop. Think of the situation of mainframes and distributed solutions. As the attractions of distributed systems grew, doomsayers were quick to predict the end of the mainframe. However, IBM developed a powerful range of integration solutions in order to allow organizations to leverage the advantages of both worlds WITHOUT having to choose one from the other. This situation almost feels like a repeat – Cloud has a lot of advantages, and some misguided ‘experts’ think that Cloud is the start of the end for on-premise systems. However, whether you believe this or not, IBM has once again ensured that it has got a running start in providing integration options to ensure that users can continue to gain value from both cloud and on-premise investments.
