First Bank获得了35％的申请性能，并通过Aruba EdgeConnect SD-Wan Edge Platform每年节省100万美元

To meet high customer expectations, St. Louis-based First Bank has fully embraced digitalization, building a hybrid cloud IT infrastructure to run everything from its core banking platform and voice system to mortgage applications and productivity solutions like Microsoft Office 365. Naturally, the bank’s wide-area network (WAN) plays a pivotal role in connecting users to these critical applications.

随着第一银行的增长，穿越WAN的数据量超过了可用的带宽并拖延了性能。第一银行首席信息安全官马克·阿什沃思（Marc Ashworth）解释说：“我们拥有一个非常传统的MPLS网络，其中大部分是T1线路。试图推动数百个兆字节的数据，只是淹没了我们的电路。”

EdgeConnect通过质量和可靠性测试

第一银行评估了SD-WAN作为对带宽问题的潜在解决方案，但没有一个供应商可以符合关键要求：在不放置语音呼叫的情况下失败了电路。因此，阿什沃思（Ashworth）咨询了当地的IT服务提供商安全数据, who told him about Silver Peak (acquired by Aruba, a Hewlett Packard Enterprise company).

彻底测试Aruba EdgeConnectAshworth总结说：“ EdgeConnect是我们遇到的第一个真正做到的产品。我们的语音系统在两个电路上运行，一个电路，我们没有拨打电话。”

Network Flexibility With Consistent Security

Following the successful test, Ashworth and his team deployed EdgeConnect appliances across all of the bank’s 105 branches, dozens of ATM locations, several home offices, and even in the data center of its cloud-based voice provider. Most sites are linked by bonded DSL and broadband circuits, or a pair of broadband circuits with LTE for backup—MPLS is completely gone.

The EdgeConnect platform also enabled First Bank to retire its conventional branch routers and leverage the built-in stateful zone-based firewall to enable adaptive breakout to trusted SaaS and cloud applications, as well as provide secure guest Wi-Fi access at the branches. Ashworth points out, “Local breakout at each branch improves overall application performance and provides a better quality of experience for our employees.”

Ashworth also foresees extending the SD-WAN with a secure access service edge (SASE) to ensure consistent security for the bank’s growing number of remote staff. “With remote users being such a big component of our environment today, leveraging SASE with the EdgeConnect platform will provide a faster, more efficient way for them to securely access assets across our network and in the cloud.”

Accelerates opening new branch locations

Ashworth notes, “We consolidated quite a bit of legacy infrastructure at the branch as we rolled out the EdgeConnect appliances. But when it came to the EdgeConnect deployment itself, that only took about 15 minutes per site. We’d just plug it in, centrally apply the business intent overlay, and we were done.”

Ashworth adds that the ease of deploying EdgeConnect will help First Bank accelerate branch openings as it continues to expand. “It depends on the availability of circuits, but typically our lead time for bringing a new branch online has gone from about 90 days to a couple weeks since having the SD-WAN.”

Boosts Application Performance and Network Uptime

The EdgeConnect SD-WAN edge platform has brought a whole new level of application performance and network uptime to First Bank. Available bandwidth has soared from 3 Mbps to as much as 200 Mbps at many sites. Ashworth quips that for First Bank employees “it’s so much bandwidth they don’t know what to do with it all.”

Greater bandwidth alone has increased application performance dramatically. In addition, First Bank implemented optionalAruba BoostWAN optimization to accelerate performance for things like HTTP traffic, file sharing, and branch backups.

Ashworth reports that for backups in particular, Boost is achieving up to 98 percent compression, and for other applications 70–80 percent compression. This translates to 35 percent higher application performance on average.

Assured WAN uptime helps serve customers better

Ashworth advises that one of the biggest benefits of the Aruba SD-WAN solution has been improved WAN availability, especially for branches where basic circuit quality is not very reliable.

“We’ve had some branches that lost both their main circuits and still kept running because they failed over to the LTE backup,” he says. “The people in the branch didn’t even know there was a problem. Maintaining that uptime is essential for our people to do their jobs and serve our clients with the best quality of experience possible.”

有力的投资回报率有节省的时间和金钱

在EdgeConnect上合并已大大简化了Wan Edge，节省了时间和金钱。阿什沃思指出，从管理的角度来看，它节省了很多时间，因为不必担心单独的分支路由器和防火墙的其他配置，更新或维护。此外，通过中心管理SD-WANAruba Orchestratormanagement console, everything from new deployments to firmware updates and network monitoring is easier.

“Overall monitoring and administration is so much easier now than with a traditional router-centric model,” Ashworth remarks. “The insights we get through Orchestrator have been really valuable for troubleshooting system or voice issues. It’s definitely freed up time for my team to focus on optimizing each branch instead of maintaining equipment.”

With less edge equipment to own and upgrade, combined with a revamped voice system, Ashworth estimates a 30–40 percent return on investment over five years. Even more dramatic, he notes, “We’ll be saving over $1 million per year compared to our previous MPLS network.”

Building Ongoing Value From EdgeConnect

Ashworth is continually exploring additional ways to benefit from EdgeConnect. For example, using physical and virtual EdgeConnect appliances, he and his team enabled certain branches to act as regional data center hubs to reduce application traffic heading to SaaS and cloud applications, as well as easing backup traffic being backhauled to the primary data center.

These new capabilities have greatly improved the bank’s disaster recovery (DR) testing. Ashworth and his team simply use adaptive breakout to point branches to the nearest data center based on geographical location. “We reduced our DR testing time by about 70 percent because of how many applications we can now run in both data centers at the same time,” Ashworth notes. “This is possible by connecting sites to the data center with the lowest latency and then failing over to the other data center if needed.”

Ashworth总结说：“ EdgeConnect SD-Wan Edge平台使我们能够做很多以前无法做到的事情。在云中使用PERM或虚拟的物理edgeconnect设备的能力使我们灵活地扩展了网络。”
