The biggest buzzword in the network industry is Cloud: the majority of organizations have a strategy to use cloud-based services and applications, whether it be Public or Private clouds. Organizations have come a long way since ’migrating to the cloud’ discussions began . Take a look at this video recorded just a few years ago when cloud was still an enigma:
But Cloud has never been a new concept: IT professionals have been migrating applications to centralized datacenters for decades now…mainly to share recourses and save money by having less IT personnel supporting branch offices. Unfortunately, application performance as well as reliability and uptime requirements quickly became barriers to this centralization. Read More »
As we start off this New Year, how about including a resolution to improve application delivery? In Best Practices for Application Delivery in Virtualized Networks – Part I , we covered key application delivery challenges that have come up due to the complexities of managing the many types of applications that enterprises use today, and further complicated by data center consolidation and virtualization. We then covered some best practices, courtesy of Dr. Jim Metzler’s 2011 Application Service Delivery Handbook, which recommended taking a lifecycle approach to planning and managing application performance.
A key step to the lifecycle approach is to implement network and application optimization tools, such as WAN Optimization solutions and Application Delivery Controllers, including server load balancers. Of course, these solutions are not new to the market and already address many of the needs that exist with delivering enterprise applications in virtualized data centers -- namely, the need to ensure network reliability, availability and security for users accessing these applications. In this post, we will discuss a recent study by IDC, where IT decision makers across Europe and the US spoke out about their strategies for using server load balancers to deal with emerging challenges.
. What important attributes do you look for in your server load balancers?
3) Growing adoption of virtualization/cloud technologies
And each of these deserves a bit more exploration. Today, I will focus on offshoring and leave the other two for future blogs.
Moving IT operations to low-cost parts of the world has been a very lucrative exercise for the past two decades. However, the financial benefits that were obvious 10 years ago are mostly gone thanks to increasing salaries in India, China, and other emerging countries combined with rising hassle costs (compliance, regulations, security, communications, language, and management) associated with off-shoring. Here is a quote from Sramana Mitra who wrote a very well publicized and much debated article in 2008 titled “The death of Indian outsourcing” (http://www.sramanamitra.com/2008/01/22/death-of-indian-outsourcing/). She writes “Rising wages in the most popular offshore centers (especially Bangalore), are eroding the cost advantage that drove this business to India in the first place. When the practice began, there was a 1:10 cost advantage. Today, this has dropped to 1:3. Over the next 5 years, perhaps, it won’t make sense to send work to India anymore.” Further complicating the offshoring play is the 20-40% attrition rates seen in many of these low-cost countries.
So it’s more or less official: the recession ended in June 2009. Anyone watching IT departments this year could have told you that. When the economy ramps up, there’s a shift in focus from cost savings and maintenance (back when I was an IT manager, we called it “bunker mode”) to innovation that moves the business forward. And in 2010 we’ve certainly observed that. IT departments are concentrating not only on streamlining operations and lowering costs—an absolute mandate of the recession—but also on innovation that leads to better business operations, greater productivity, and increased revenues—a clarion call of recovery. Now, this innovation can be in business practice or improved technology—and most likely both—but it almost always begins with IT. Streamlining IT functions, managing assets carefully, and ensuring uninterrupted operations can lower costs, increase reliability, and free resources for research, development, and innovation.
So it’s back to business as usual running IT departments and data centers in an expanding recovery, right? Wrong.
You’ve probably seen the spinning “loading” wheel or the dreaded “hour glass” quite often in your Internet browsing experience, especially on rich media sites where videos download to your browser. You blame your ISP and move on. Lucky you.
Imagine if you are a store clerk manning the cash counter at a local big box store on Black Friday. Your POS application just went down, and the “self-service” counters have just blacked out. A collective sigh that goes up in the line doesn’t help either.
Now whom do you blame?
There are many layers to this problem. A typical business information ecosystem combines hardware—storage, servers, large computing capabilities; software applications—graphic interface driven information manipulation solutions; and the glue that connects them all—networking.
