Two examples are Appriss’ flagship VINE (Victim Information Notification Everywhere) and NPLEx (National Precur sor Log Exchange) solutions. VINE alerts victims of crime when the criminals who preyed upon them are released from prison. NPLEx is an electronic service that monitors the sale of over-the-counter cold medications containing pseudoephedrine, a key ingredient in the manufacture of methamphetamine. If an individual trying to buy one of these drugs is beyond the legal limit in his or her purchasing history, NPLEx alerts the cashier, blocking the sale.
In short, Appriss solutions require speed, reliability and high availability to be able to process the data and notify users in near real-time, potentially 24x7x365. Because of these demanding conditions, Appriss has faced several IT challenges over its 20 years of business. About ten years ago, Appriss decided to rewrite its software on JAVA to improve its solutions’ performance and enable the software to make automated calls and emails, a critical functionality today. At the time, its solution functionality ran on Windows, but Appriss needed a platform that could run Java faster and more efficiently.
More recently, after years of running its massive Oracle databases on HPUX, it was time for a change. Oracle support for HPUX was phasing out. Running HPUX entailed other limitations as well. Travis Eckert, Infrastructure Manager at Appriss, says, “As a technology manager at Appriss, I look to avoid vendor lockin. When we were on HPUX, we were not only tied into Hewlett Packard for their software, but tied to the hardware as well.”
That was not the only issue. Ackert explains, “I had to assign two dedicated personnel to HPUX and send them to special training.” One day, the unthinkable happened. Both HPUX specialists were sent to a conference and were in flight when an HPUX issue occurred. Although they were able to fix the problem from 30,000 feet, the handwriting was on the wall for HPUX
Appriss’s successful business growth and the resulting virtual and physical server expansion produced the third challenge. Ackert explains: “Every year we come up with maintenance tasks, a list that needs to be done just to keep things running. That list always includes patching the servers quarterly. A couple of years ago, we were lucky to patch all of the servers every two years.”
In all of these cases, Appriss chose SUSE solutions. Due diligence in replacing its Windows servers revealed that Linux was the fastest and most efficient operating system for running JAVA-based applications. Appriss liked the affordable SUSE subscription model—and chose SUSE Linux Enterprise Server to replace its Windows servers.
To replace HP-UX as the operating system running its databases once again Appriss chose SUSE Linux Enterprise Server. Ackert says, ”SUSE is based on open source and uses standards-based technology; there’s no vendor lockin.” In addition, with SUSE Linux Enterprise Server the entire Appriss IT team of nine could handle the SUSE OS.
What’s more, the price of a SUSE subscription was right and conducive to growth. “The SUSE unlimited virtual machine license allowed us to scale cost-effectively by adding an unlimited number of virtual machines to a licensed physical server at no extra charge,” says Ackert. He also liked SUSE support. When the company migrated to SUSE Linux Enterprise, it had some performance issues with the databases. SUSE sent in high-end technical consultants who fixed the problem at no charge.
SUSE helped with other improvements, too. When Ackert joined the company, it was experiencing outages in its Citrix Xen hypervisor. The company switched to SUSE’s Xen hypervisor and purchased and installed the SUSE Linux Enterprise Server High Availability Extension (HAE). This eliminated outages and improved uptime. The High Availability Extension sits on top of SUSE Linux Enterprise Server and enables Appriss to create a robust, redundant virtual platform on two physical servers where Appriss has spun up many instances of SUSE Linux Enterprise Server for individual services. If one of those two pieces of hardware were to fail, all the VMS running on it can be started up on the other system instantly—maintaining availability.
Today Appriss has 500 to 600 servers (a combination of physical and virtual machines), running the SUSE Linux distribution. These servers run the company’s JAVA applications, databases and web, FTP and email workloads. Most of these servers are located in two data centers in Louisville, Kentucky. In addition, Appriss has been spinning up virtual instances to the Amazon Web Services (AWS) public cloud.
ACCELERATING SYSTEM MANAGEMENT
The final piece of Appriss’ SUSE solution is SUSE Manager, which automates updating, patching, updating and configuring Linux servers across physical, virtual and cloud environments from a single console. When Appriss saw SUSE Manager at a SUSE event, the product immediately clicked as the remedy to the company’s time-consuming maintenance burden. Appriss bought and installed the product and today manages all its servers faster and more accurately with SUSE Manager.
Also quantifiable is the time savings generated by SUSE Manager. Ackert says,” SUSE Manager has improved our patching process dramatically. Before, I was lucky to get every server patched within two years. Instead of spreading out the patching among all the engineers, now I have one engineer who can patch all of them quarterly.”
Faster patching also means better security. “The initial reason to buy SUSE Manager was its ability to respond quickly to issues that need patches, such as OpenSLL vulnerabilities,” Ackert says. In one such incident, after SUSE rapidly sent the security patch, using SUSE Manager, a single member of the IT team patched the entire SUSE Linux environment in four hours—and expressed surprise at praise from the company chief security officer: “I clicked ten buttons in SUSE Manager and all the servers started patching themselves. I was done within four hours, so I don’t know what they’re thanking me for.”
High availability (HA) is another benefit. The High Availability Extension helps minimize unplanned as well as planned down time. If one machine in a cluster has an outage, the extension switches processing to another machine in the cluster, preventing downtime. And it is now looking at adding the SUSE Live Patching technology, which can patch servers without downtime.
Finally, a key benefit for Appriss is the flexibility they get from SUSE’s open source, standards-based technology. “SUSE is very adaptable,” says Ackert. “That allows us to build on top of SUSE as a platform. Appriss is now looking at some open source software that will allow it to move its virtual machines from one data center and network to another or to and from AWS and not be tied into a physical infrastructure. “It’s all about flexibility,” Akert says.
