Five questions you should ask to detect and fix app and network performance issues

Selecting the right end-to-end performance management solution to help you “detect & fix” problems faster

QUESTION #1 - How many business-critical applications do you have and how quickly do you need to troubleshoot them when they’re slow?

Determining the types and number of business-critical applications your business uses every day can help you to narrow your focus when selecting a performance management vendor. Focus on how fast you need to Detect and Fix network and application problems – maybe even before they impact your users. Just finding all the applications running RIGHT NOW across you network can often lead to some unexpected discoveries and insights. For example, shadow IT apps that your users have downloaded and are being used on an ad hoc basis could be consuming more bandwidth than you anticipated. SteelCentral network performance management (NPM), in conjunction with SteelHead application acceleration, can help by quickly and automatically identifying all the applications on your network – business and recreational – so you can effectively troubleshoot, plan for growth, and police the network, if necessary.

QUESTION #2 – Do you have the ability to guarantee the performance of your business-critical applications?

Business-critical applications that are being crowded out by a couple of individuals in your branch office listening to streaming radio can cause a slowdown that you cannot afford to endure. You caught and stopped them this time, but how do you prevent this from happening again? If you are using SteelHeads to optimize the branch traffic, you could implement QoS to make sure latency-sensitive apps like VoIP and video get top priority, business-critical apps come next, and recreational apps are delegated to the best-effort category.  But is that enough? How do you make sure that QoS is working as expected – that your VoIP phones in the sales office aren’t experiencing jitter because someone accidently mismarked the local router? Only SteelCentral NPM provides centralized reporting and monitoring of SteelHead QoS classes and sites to ensure proper categorization and easy troubleshooting.

QUESTION #3 – Do you have the necessary resources to devote to the day-to-day operation of your business-critical applications?

Balancing strategic projects with day-to-day operational needs is challenging at the best of times.  Throw in a few “fires” to put out and the best laid plans go by the wayside. Establishing your solution requirements for troubleshooting and fixing application slowdowns and outages—for example, focusing on gaining comprehensive visibility of your most business-critical applications—is crucial in ensuring that you get the best “fit” for your business goals. Be sure to think up front about factoring in any needed implementation services, as well as ongoing maintenance and other support.

Riverbed Professional Services offers a full complement of training, implementation, and ad hoc consulting services. You can also engage resident consultants to fill-in any people or skills gaps that you might currently be experiencing.

QUESTION #4 - What will your business need from IT to handle growth and future business goals?

No business can, or at least should, remain static for long. Therefore, as with any solution that you plan to keep for a while, you should plan not only for what you need now, but also what need in the foreseeable future. A good place to start is to understand the trends of overall application consumption and bandwidth usage. You need to get a handle on historical data for which apps are being consumed, by whom, where in the network (for example, branches vs. data centers or cloud), and by what type of networks (MPLS, Internet, and with or without VPN). This will show you how scalable a solution you’re going to need in order to keep a close watch over how those applications get delivered to the business.

SteelCentral works with SteelHead to deliver analysis and reporting of the benefits achieved through WAN optimization and to identify additional sites that could benefit. Together they help troubleshoot performance issues in remote offices without the need to send expensive IT resources onsite and provide visibility for making good decisions about when to select one network path versus another to help balance the tradeoff between performance and cost.

Application Visibility

Figure 3: SteelCentral NetShark and SteelHead automatically recognize more than 1100 business and recreational applications so you know what’s running on your network. In this case, BitTorrent is using one-fifth of the bandwidth!

QUESTION #5 – What is comprehensive end-to-end application visibility worth to your business?

Of course, the answer to this question can be quite complicated. For example, even if you don’t want to pay for a robust, full-featured troubleshooting solution, you will still need to figure in the costs of your IT people’s time (and it’s never just one person, there’s usually a “war room” full of people!) and effort to do the job manually. A complete ROI analysis also needs to include the costs and risks associated with slow or unavailable applications, which in many cases may directly impact revenue, sway employee and customer satisfaction, or damage your business reputation. Will the “cheaper” solution really be cheaper if it can’t help find the problem and help you get your application running at full speed quickly?
