THE DATA CENTER JOURNAL | 23 www.datacenterjournal.com We are in the midst of a once-in-a-decade shift in the technology landscape. Industry experts anticipate a 44 percent annual growth in cloud-based workloads over the next several years, and the cloud infrastructure market is expected to grow by 19 percent annually over the next two years. Despite this explosive growth, most businesses and IT professionals have acknowledged that although the cloud might be for everyone, it's not for everything. By kong yang The Top Three Hybrid IT Myths Debunked t he compromise, a strategy known as hybrid IT (mov- ing some IT services to the cloud while continuing to maintain some critical services on site), offers organi- zations the best of both worlds and is considered the future of IT. But many misconceptions and concerns about its operation remain. Here are three of the most prevalent myths about hybrid IT debunked. myth 1: the cloud won't deliver the same level of performance and availability as my on-premises infrastructure. ere's certainly an element of truth to this one, but like most myths it was made to be busted. Several years ago, when cloud computing had just taken off, consistent performance and high availability were notable issues and legitimate barriers to adoption. But with the natural maturation of the technology and the introduction of critical cloud performance monitoring, man- agement and tuning tools, organizations can rest easy knowing the cloud can meet the performance and availability require- ments of even some of the most demanding applications. Consider cloud storage as an example: a couple of years ago, shared storage systems in the cloud delivered very unpre- dictable performance, which sometimes slowed to a crawl. But the architecture of today's cloud storage systems—oen based on SSDs, storage-optimized instances and guaranteed performance options—offer up to 48,000 IOPS, which is more than enough performance to satisfy most organizations' processing needs. And although just a few years ago outages and downtime in the cloud were commonplace, today's cloud-provider SLAs— combined with the simplicity of setting replicas, standby systems and the durability of data stored in the cloud—oen exceed what IT departments can deliver with an average on-premises system. Nevertheless, IT professionals are still ultimately responsible for overall performance and availability. To that end, it's critical to monitor resource contention and bottlenecks and to strategically
