![]() Preventable disaster deathsĬountries with effective early warning systems have disaster death rates that are eight times lower than countries without, suggesting most disaster deaths are preventable.Įarly warning systems offer a relatively cheap and effective way of protecting people and assets from hazards, including storms, floods, heatwaves and tsunamis. The World Meteorological Organization (WMO) and the United Nations Office for Disaster Risk Reduction (UNDRR) are spearheading the initiative, with UN technology agency ITU and the International Federation of Red Cross and Red Crescent Societies (IFRC) also providing crucial input. In response, EW4All is promoting programmes to strengthen climate mitigation in developing countries. People in Africa, South Asia, South and Central America, and small island states are 15 times more likely to die from climate disasters, according to UN statistics. “When disaster strikes, people and communities can turn to technology as a lifeline,” said Doreen Bogdan-Martin, Secretary-General of the International Telecommunication Union (ITU), which is leading one EW4All pillar.Īs the impact of climate change becomes ever more apparent, vulnerable developing countries are paying the heaviest price. ![]() Today, half of countries still lack early warning systems, while fewer have regulatory frameworks linking early warnings to emergency plans. The UN Early Warnings for All Initiative (EW4All) aims to ensure everyone on Earth is protected by early warning systems by 2027.ĭigital technologies form an increasingly crucial component of national disaster-readiness infrastructure, enabling effective dissemination of early warnings. “We needed to be able to write or load data into our data storage solution very quickly without interfering with the reading and querying of the data at the same time.The people least responsible for climate change are suffering most from extreme weather, United Nations officials noted this week while stepping up plans to ensure everyone worldwide receives adequate warnings as natural disasters increase. Data loading delayed the delivery of our reports,” says Hunt. “We have to both load and consume the 30 billion records in a time period between market close and the following morning. More sophisticated trading practices lead to a massive growth in data and it was critical that Nasdaq started planning to evolve a new architecture to continue to achieve the performance standards and operational excellence that the ecosystem expects. “When market volatility increased in early 2018, data volumes for the warehouse grew substantially, peaking at about 55 billion records per day in 2018,” says Hunt. Users rely on the data to complete billing, reporting, and surveillance. The overnight batch processing that runs against the warehouse caused challenges in processing enormous volumes to meet stringent deadlines. Over time, growth in data led to a change in approach for managing that data for analytics. By 2018, the solution ingested financial market data from thousands of sources nightly, ranging from 30 billion to 55 billion records and surpassing 4 terabytes. Between 20, this Amazon Redshift cluster grew to 70 nodes as the company expanded the solution to support all its North American markets. ![]() In 2014, to increase scale and performance and lower operational costs, Nasdaq moved from a legacy on-premises data warehouse to an Amazon Web Services (AWS) data warehouse powered by an Amazon Redshift cluster. Every night, Nasdaq receives billions of records that need to be loaded for billing and reporting processes before the markets open the following morning.Īs automated trading platforms have entered the market, the pace and volume of transactions has grown. “This data includes orders, quotes, trades, and cancellations,” says Robert Hunt, vice president of software engineering for Nasdaq. Nasdaq relies on an internal application to capture and store all protected exchange data. ![]() The Nasdaq Stock Exchange is the largest equities franchise globally by volume, and it manages the matching of buyers and sellers at high volume and velocity, while providing data feeding the price quote for stocks in electronically entered trades. It is home to nearly 4,000 listed companies globally across its markets and also provides its mission-critical technology to other market infrastructure operators located in 50 countries. Nasdaq operates a total of 27 markets, a central securities depository, and clearinghouse across a variety of asset classes in North America and Europe. ![]() Nasdaq is a multinational financial services and technology corporation that owns and operates the Nasdaq Stock Exchange. ![]()
