Data centers trends and challenges

With the explosive growth of Web 2.0, software-as-a-service (SaaS), cloud computing and other emerging Web-based applications, datacenter workloads have increased exponentially. The business opportunities that are created from the deployment of these new applications are substantial, but the demands they place on the datacenter are daunting. Challenges include:
Unprecedented data growth. Recent studies indicate that the amount of data managed by today's datacenters will quadruple every 18 months. To complicate matters, online users are getting much more sophisticated, and response time expectations are at an all time high. But with the large increases in data volume, user interaction times are actually increasing for many datacenters.
Severe capacity constraints. Datacenter managers are struggling to manage huge increases in rack, power and network utilization. They are constrained by limited datacenter power and space and are seeking cost-effective ways to expand capacity without increasing the datacenter footprint.
Increasing data complexity. Organizations have too much data to process in a time-sensitive and consistent manner. Information management requires extensive data partitioning and application-level mapping, caching, replication/recovery and load balancing. Existing data management tools are complex and existing commodity, non-application-specific hardware is difficult to use and manage.
Lack of scalability. Current datacenter environments lack the ability to scale effectively to manage peak demand. Even in multi-core server environments, many datacenters have already scaled to the point they are memory and disk bound.
Underutilized resources. Estimates of current datacenter equipment utilization rates run between five and 30 percent. Kilowatt-hours are very expensive and inefficient. Underutilized hardware translates into wasted capex and opex, as well as increased power consumption.
Severe budget constraints. Budgets are tighter than ever. Only solutions that are able to provide quick return on investment (ROI) are now being approved. Traditional approaches to datacenter expansion are no longer viable.
Corporate mandates to go green. According to the 2007 EPA Report to Congress on Server and Datacenter Energy Efficiency, the energy consumption of servers and datacenters has doubled in the past five years and is expected to almost double again in the next five years to more than 100 billion kWh, costing about $7.4 billion annually. Datacenter managers are working hard to save energy, reduce datacenter space requirements and protect the environment
To overcome these challenges consult a datacenter hosting service or managed hosting service.
