... to fit on a mobile device for end-user access. Instead, turn application access into message processing. That notion comes from ClairMail Inc. in Novato, Calif. According to CEO Joseph Salesky, people are mobile, but desktop applications aren't, and IT's attempt to give the apps some mobility has been like "trying to squeeze an elephant into the doghouse." For example, a lot of desktop software is dependent on using multiple windows on a monitor, Salesky says. But, he points out, small handheld displays mean that "mobile devices don't window well." That's why his start-up company is offering a message- access process for mobile users beginning this week. End users put application access links into their devices' contact lists. When they need access, they simply click on a link, like they would to make a phone call or send an e-mail. Data can be retrieved or entered based on a user's rights, which are checked against the privileges stored in a company's network directories. A ClairMail appliance sits behind the corporate firewall and handles all of the message transactions, so no client-side software is necessary, Salesky says. He adds that combined with an application's user-authentication processes, the ClairMail appliance's knowledge of the "trusted path" to a specific device adds two-factor security, since both the user's identity and the handheld are verified. ClairMail is releasing its technology with scripts for accessing software and services from vendors such as Salesforce.com Inc., Business Objects SA and BMC Software Inc. 's Remedy unit. Next year, the company will release access scripts for Siebel Systems Inc. and SAP AG apps, Salesky says. Annual fees start at US$60 per user.
Forget about the engineer, but still ...
... get long-distance fault tolerance. Ron McCabe, CEO of MiraLink Corp. in Portland, Ore., quips that traditional WAN-based fault-tolerant systems "are so complex, they ship with an engineer." On the other hand, McCabe claims that his company develops appliances that handle fault-tolerant needs and don't require a BSEE grad to tag along with the technology. "Anyone who can manage an IP address or SCSI drive can use it," he boasts. MiraLink's data-mirroring devices use the company's IntelliBuffer software to write data to remote servers while saving the information to the primary system, McCabe says. He adds that in the event of a primary server crash, databases can be rolled back to the transaction processed just before the server hiccup. MiraLink's high-end unit can handle up to 120GB of data per hour. Next month, the company will roll out a low-end appliance, Model 400, which will be able to save as much as 8GB of information to remote servers hourly. It will be priced at under $4,000.
Or virtualize your apps to achieve ...
... local fault tolerance. That's the approach taken by Appistry Inc. in Crevecoeur, Mo. CEO Kevin Haar argues that "applications should transcend the infrastructure" and be virtualized to achieve fault tolerance. Appistry does that through its Enterprise Application Fabric software, which will be updated with a 3.0 release in Q1 of next year. The new version will dynamically store data in memory on multiple servers on a LAN segment, much like a RAID storage system secures saved data to multiple disk drives. When one server fails, the Appistry software, which maintains the state of every transaction, simply grabs needed data from another machine in the fabric so transactions can continue unaffected. What's more, says Haar, the software can automatically provision a new server when it's attached to a LAN segment. Subscription-based pricing starts at $1,950 per CPU on an annual basis.
