F5 Ensures High Availability for Leading Software-as-a-Service Provider

F5 Networks, Inc. (NASDAQ:FFIV), the global leader in Application Delivery Networking (ADN), today announced that Varolii, market leader in Software-as-a-Service (SaaS) Customer Interaction Management (CIM) solutions, is using F5 products to guarantee the highest application availability for its customers, including prominent Fortune 1000 and Fortune 500 companies.

“F5 technology gives us much stronger reliability and redundancy for our cloud services, so we can confidently deliver B2C customer interaction applications that demand near 100 percent uptime. These applications are being used to communicate in a time critical manner with over three million U.S. consumers per day,” said David McCann, President and CEO of Varolii.

One major U.S.-based airline depends on Varolii to send its passengers updated flight information via personalized voice, text, or email messages. Another airline uses a Varolii automated communication application to adjust flight and ground crew schedules when necessary. During Superstorm Sandy in November 2012, more than 150 large U.S. organizations used Varolii solutions to send critical communications to their employees, crisis teams, state and local emergency responders, utility customers, and students.

Prior to implementing F5 technology, Varolii relied on slower, expensive network systems and had to manually redirect web traffic to alternate data centers by configuring each application. But several years ago, the organization installed BIG-IP Local Traffic Manager (LTM®) devices, which enabled Varolii to quickly and easily direct network traffic across multiple servers to guarantee the highest application availability. Varolii also deployed several BIG-IP Global Traffic Manager (GTM™) devices, which help the company provide near-instantaneous geo-redundant operational capabilities.

“We looked at several different technology vendors, but F5 was the only one that offered the combination of great features, platform flexibility, and manageability,” said McCann. “Every customer application we support goes through BIG-IP LTM and GTM. F5 has become an essential part of our entire infrastructure—and our Fortune 500 clients expect world class SLAs and applications that are always running and must work at critical times.”

The F5 solution has also helped Varolii reduce the service recovery window for one of its most critical applications from 45 minutes to 30 seconds. In addition, with BIG-IP LTM, Varolii has eliminated up to four hours of monthly planned maintenance outages for customers because it no longer has to manually redirect traffic. The F5 technologies have also played a role in the organization’s data center consolidation, which reduced the number of servers by 40 percent.

“We recognize how critical performance, availability, and reliability are to SaaS vendors like Varolii and other enterprises that deliver cloud-based services to hundreds of thousands of customers,” said Jason Needham, Vice President of Product Management and Product Marketing at F5 Networks. “Using F5 BIG-IP LTM and GTM, Varolii has the peace of mind knowing they can always deliver highly reliable applications that perform at the fastest levels and flexibly handle peak workloads. And they never have to worry about downtime.”

Containers are all the rage among developers and web companies, but they also represent two very substantial benefits to larger organizations. First, they have the potential to dramatically accelerate the application lifecycle from software builds and testing to deployment and upgrades. Second they represent the first truly hybrid-approach to consuming infrastructure, allowing organizations to run the same workloads on any cloud, virtual machine or physical server. Together, they represent a ver...

Overgrown applications have given way to modular applications, driven by the need to break larger problems into smaller problems. Similarly large monolithic development processes have been forced to be broken into smaller agile development cycles. Looking at trends in software development, microservices architectures meet the same demands. Additional benefits of microservices architectures are compartmentalization and a limited impact of service failure versus a complete software malfunction....

With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...
DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, will explore HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.
The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.
