SaaS: integration in cloud

Ingres then selected a core group of enterprise products that included the Salesforce CRM suite, accounting software from Intacct and human resources solutions from ADP. “In our selection process, we gave priority to SaaS software products that were compatible with other products,” says Doug Harr, CIO of Ingres. “We wanted to use best of breed, rather than a SaaS product that tried to do everything but left some of our users unhappy.”

Getting each of those applications in place was just a first step; Ingres then sought a method for integrating them so that they would function together. Ingres narrowed the choices down to the products, each of which had different strengths. Overall, Harr found that AtomSphere from Boomi was the farthest along in its ability to integrate SaaS products. “Boomi already had connectors for the software we were using,” Harr explains, “and it was a true multitenant SaaS product, not a hosted ASP solution.”

Ingres integrated employee-oriented applications such as Salesforce and the HR software from ADP so that activities such as expense reporting could begin as soon as new employees were hired. Next, the company plans to integrate additional products and move its business intelligence (BI) functions to Amazon.com.

“The innovation of the Amazon EC2 service is its elasticity, which allows dynamic provisioning of enough computing and storage capacity to hit peak workloads, and then allows a scale-back,” Harr says. “That elasticity provides greater agility than traditional managed services environments and is priced on a variable cost basis.”

Boomi was founded in 2000 with the goal of simplifying the integration process, and developed products with a graphical interface that eliminated the need to write code by using drag-and-drop techniques to define linkages. In 2006, the company decided to address the issue of integration in the cloud. “We looked at SaaS and were convinced that integration was posing some significant problems,” says Bob Moul, CEO of Boomi. “And without good integration, the full potential of the cloud could not be tapped.”

Launched early in 2008, AtomSphere is an integration PaaS that is used most often by Boomi to integrate cloud and on-premise applications. Only about one-fourth of Boomi’s customers are exclusively in the cloud at this point, according to Moul. Boomi focused on the most popular SaaS software. Connectors have been built for several dozen products ranging from small business software such as Intuit’s QuickBooks, to enterprise products such as Oracle’s Business Suite.

Since AtomSphere itself is a SaaS product, it embodies all the advantages of SaaS, including rapid updating. “When an API is modified, we make the change and everyone gets it at once,” Moul says. AtomSphere also offers ease of use that is consistent with Boomi’s original mission of simplification, with wizards that lead the user through the process of configuring connectors, so that business users are able to define and implement business processes.

Gartner predicts solid growth over the next few years for both SaaS applications and cloud service brokerages. “Organizations have come to the point where they are frustrated with internal IT departments and with the large financial outlays for on-premise software,” Plummer says. “They are actively looking for alternatives, and cloud computing holds a lot of promise for alleviating these problems, as well as providing innovative options for improving business operations.” 

Goodbye SaaSHello SlaaS?

In 1998, eGain launched its suite of e-services in the then-nascent application service provider (ASP) market, precursor to today’s software as a service. Hosted software pioneer and eGain co-founder Ashutosh Roy believed everything belonged on the Web but discovered customers wanted the option of a license, so eGain added on-premise solutions as well.

As time went on and the company grew, “managed services” were added, which bridge the gap between on-premise and hosted environments, allowing customers to still purchase a software license inside the firewall after a hosted contract for, say, a year or two.

Now along comes solutions as a service (SlaaS). “The biggest difference in SlaaS, as the client sees it, is the fact that we are not locking them into a contract. We give them the flexibility to go up and down on a usage-per-month basis, and they can stop their use of eGain whenever they want to,” Roy says.

What’s the catch? He explains, “Customers are ‘paying more for a drink,’ but they still have the option of migrating to a long-term contract when the need arises.”

Building trust in the cloud

Users of individual SaaS products have generally become confident that their vendor is proficient in maintaining security, ensuring that data is backed up and carrying out other support tasks. However, venturing more broadly into “the cloud,” where many applications may be used as services, is a different matter; establishing trust with numerous third-party suppliers is a complex process.

To help address the problem, Vordel introduced the Vordel Cloud Service Broker in November 2009. It manages multidomain cloud services by registering them in a single repository to facilitate monitoring and policy enforcement. Cloud Service Broker also optimizes performance by providing caching, acceleration and data transformation.

A large retailer is using the Vordel Cloud Service Broker to manage connections to an Amazon service, the Amazon Gift Codes on Demand (AGCoD). That service replaces plastic gift cards by distributing them via e-mail, HTML or paper. It is accessed through a Web Service API that exposes Amazon’s technology to other systems. The Vordel Cloud Service Broker provides the necessary authentications and digital signatures. The monitoring capability lets the retailer track service frequency and usage via Flash-based metrics and Web-based reports.

“With the emergence of SaaS and storage as a service, customers wanted to create composite applications that included components from the cloud,” says Vic Morris, CEO of Vordel. “But with this complexity comes the need for monitoring and management.”

Although many companies start with non-mission-critical applications for their cloud services, use is expanding rapidly. “It is a compelling model,” Morris says, “and one that is growing rapidly in the KM space.” Vordel, which has a history in XML and SOA integration, is also exploring the opportunities for matching customers with the burgeoning list of available cloud services.
