Explosive growth of Smart Meter (SM) deployments has presented key infrastructure challenges across the utility industry. The huge volumes of smart meter data has led the industry to a tipping point which requires investments in modernizing existing data warehouses. Typical modernization efforts lead to huge capital expenditures for DW appliances and storage. Sizing this new infrastructure is tricky and can lead to underutilized or poorly performing hardware. The Cloud is the catalyst to solving these Big Data challenges. Utilizing a Cloud architecture delivers huge benefits by: Maximizing use of existing architecture Minimizing new CapEx expenditures Lowering overall storage costs Enabling scale on demand
