LATEST INTELLIGENCE Devising a Cloud Strategy that Doesn’t Cast a Shadow on App Performance IT Evolution to a Hybrid Enterprise Drives the Need for Location-Independent Computing The move to the cloud comes with visions of always on applications, happy, productive users, and anytime, anywhere access. It touts itself as the answer to all of your on-premises application problems, providing a highly scalable and secure infrastructure on which to host your most critical applications. But that same move is actually burdened by performance issues like low response times or high latency, at a time in our industry when users have the highest level of expectation around application speed and availability. Performance is the penalty that you pay in exchange for the agility, flexibility and cost savings of the cloud. All this leads to poor end-user experience and can cause a resulting negative impact on the organization’s ability to operate efficiently and effectively. Enterprise IT has gone through several waves of evolution since the birth of computing. The computing platform has evolved from mainframe computing to minicomputers, shifted to client/server computing, and finally moved to Internet computing in the cloud era. Each transition saw computing evolve in the following ways:  • The cost of computing fell by orders of magnitude, enabling businesses to deploy more compute resources to handle almost every business process. • The primary computing location has continued to change. Compute resources have shifted from the data center to the campus and branch office, back to the data center, and now to endpoints and the cloud. IT has had to continually adapt as the primary compute location has changed. • The network has continued to grow in importance with each successive compute transition. Historically, the network has tied all of the compute resources together. The network plays a more important role today, though, as increasingly more applications have become network centric. The network can optimize application flows and provide the necessary visibility required to manage emerging compute models such as mobile and cloud. • Core network infrastructure has expanded. Historically, routers and switches were the building blocks of the network because they created the connections between points. However, connectivity alone isn’t enough to run the business efficiently. The network must provide users with an optimized experience to maximize productivity. Because of this, technology such as WAN optimization and network management tools now must be considered core network infrastructure. Whether you’re moving to the cloud, or are already there and are trying to figure out a better way to do the cloud, the question becomes is there a way to utilize the cloud that ensures the highest level of performance possible? You fall neatly into one of two camps when reading this paper — either you have an application on-premises and are looking for the best way to move to the cloud, or you are already in the cloud and are experiencing performance issues, causing you to look for a better way. Regardless of which camp you belong to, you’re still in the same position of looking for the right way to have an application hosted in the cloud with the highest level of achievable performance possible.
