VoltDB lance la réplication croisée de centres de données sans perte Active(N)

Une capacité brevetée permet à la plate-forme de données VoltDB de répliquer les données dans plus de trois centres de données à la fois tout en atténuant les conflits de données

BEDFORD, Massachussets, 31 août 2021/PRNewswire/ — En réponse directe aux besoins de ses principaux clients, travaillant avec certains des plus grands opérateurs télécoms du marché, VoltDB, la principale plate-forme de données de niveau entreprise construite pour permettre une prise de décision rapide en matière de données, a annoncé aujourd’hui l’introduction de sa réplication croisée de centres de données (XDCR) Active(N)tm Loseless. Active(N) Lossless XDCR donnera aux opérateurs de télécommunications et aux entreprises qui cherchent à mettre en place des cas d’utilisation de la 5G un avantage considérable en augmentant la résilience de leurs réseaux contre les pannes et les risques de sécurité, ainsi qu’en ajoutant une protection supplémentaire contre la perte de données.

Active(N) Lossless XDCR réplique les données en temps réel dans quatre centres de données ou plus à la fois, ce qui permet d’obtenir une disponibilité « cinq neuf » (c’est-à-dire 99,999 %), qui devient rapidement indispensable à l’ère de la 5G.

« Nous venons d’élever la barre en matière de cohérence, de résilience et d’évolutivité des données », déclare Dheeraj Remella, directeur des produits chez VoltDB. « Nous pouvons maintenant offrir un niveau de réplication de centre de données qu’aucune autre plate-forme de données ne peut offrir, et cela permet vraiment aux entreprises d’avoir une disponibilité et une résilience infaillibles intégrées à leur architecture afin qu’elles puissent augmenter considérablement leur succès dans la monétisation de la 5G. »

La promesse de latence ultra-faible de la 5G crée de nouveaux cas d’utilisation qui obligent les données à être à la fois immédiatement disponibles et cohérentes, quelle que soit la localisation de l’utilisateur. Ce nouveau paradigme conduit inévitablement à des conflits de données. La solution XDCR unique de VoltDB offrira aux opérateurs de télécommunications et aux entreprises la possibilité unique de résoudre les conflits à la fois au niveau de l’application et de la base de données, afin de maintenir la résilience et la cohérence des données, même à des latences inférieures à 10 millisecondes et quel que soit l’endroit où les données sont stockées, dans un seul ou plusieurs centres de données

« N’importe qui peut effectuer des transactions rapidement », a déclaré Remella. « Nous donnons à nos clients les moyens de les faire rapidement tout en observant puis en corrigeant les inévitables conflits qui surviennent lorsque le même enregistrement est modifié dans plusieurs centres de données en même temps. Cela place les opérateurs de télécommunications et les entreprises qui utilisent VoltDB dans une position unique pour fournir une protection sans précédent contre les défaillances des centres de données et les cyber-attaques, tout en fournissant un accès aux données incroyablement rapide pour leurs applications distribuées dans le monde entier, y compris les applications critiques. »

Avec Active(N) Lossless XDCR, VoltDB enrichit sa plate-forme de données de niveau entreprise avec une fonctionnalité sans précédent pour aider les clients à se différencier dans la feuille de route vers l’automatisation et la transformation numérique et à construire des réseaux robustes qui permettent un déploiement et une monétisation plus rapides des cas d’utilisation de la 5G.

UN Study: Weather Disasters Increased Fivefold in Last 50 Years

A new report released Wednesday by the United Nations indicates extreme weather events have increased fivefold over the past 50 years, while the number of fatalities related to those events has dropped.

Officials from the U.N.’s weather and climate agency, the World Meteorological Organization, introduced the report during a briefing from the agency’s headquarters in Geneva. The report shows weather-related disasters have occurred on average at a rate of one per day over the past five decades, killing 115 people and causing $202 million in losses daily.

Mami Mizutori, U.N. special representative for disaster risk reduction, told reporters she found the report “quite alarming.” She noted that this past July was the hottest July on record, marked by heat waves and floods around the world. The study shows that more people are suffering due to this increased frequency and intensity of weather events.

Mizutori said 31 million people were displaced by natural disasters last year, almost surpassing the number displaced by conflicts. She said on average, 26 million people per year are pushed into poverty by extreme weather events. Now, the COVID-19 pandemic is compounding the problem.

The U.N. disaster risk specialist said, “We live in this, what we call, the multihazard world, and it demonstrates that we really need to invest more in disaster risk reduction and prevention.”

WMO Secretary-General Petteri Taalas said the good news in the report is that during that same period, fatalities related to these disasters dropped by nearly three times, due to early warning systems and improved disaster management.

But the study also shows that more than 91% of the deaths that do occur happen in developing or low-income countries, as many do not have the same warning and management systems in place.

The WMO officials said the economic losses associated with these disasters will worsen without serious climate change mitigation. Taalas said if the right measures are put in place, the trend could be stopped in the next 40 years. WMO called on the G-20 group of world economic powers to keep their promise to reduce greenhouse gas emissions.

Four Killed, Dozens Kidnapped in Eastern Congo Ambush

BENI, DEMOCRATIC REPUBLIC OF CONGO – Four civilians were killed and dozens were taken hostage Wednesday in eastern Democratic Republic of Congo when suspected Islamist militants ambushed a convoy and set fire to the vehicles, the government said.

Congo’s army has freed more than 50 of the hostages in Ituri province and operations are underway to recover the remaining captives from the Allied Democratic Forces (ADF), a Ugandan Islamist group, the communications ministry said on Twitter.

The ministry did not say how many people were still being held hostage. A local lawmaker said earlier that about 80 people were believed to be missing after the attack on a convoy of about 100 vehicles that was traveling with army protection on the road between the cities of Beni and Butembo.

Attacks by the armed groups operating in eastern Congo’s borderlands with Rwanda and Uganda have continued unabated despite the government’s imposition of martial law in Ituri and North Kivu province at the beginning of May.

The installation of army generals as provincial governors was meant to quell a surge in violence that the military largely attributes to the ADF.

But the number of civilians killed in such attacks has increased, according to the Kivu Security Tracker. Survivors of Wednesday’s attack recalled a hail of gunfire as the convoy passed near the village of Ofaye.

“Bullets started flying in every direction,” one of the survivors, Malanda Dague, told Reuters. “Some vehicles were hit and then burned.”

Jean-Paul Ngahangondi, a member of parliament in North Kivu province, where the convoy started, criticized what he said was the army’s slow response, a frequent complaint of local people.

“The army just waits for the rebels to kill the population and only then pursues them without any positive results,” he said.

Eastern Congo has been plagued by violence since regional wars around the turn of the century. Islamic State has claimed dozens of killings blamed on the ADF, although U.N. experts say they have not found conclusive evidence that IS has control over ADF operations.

Thousands of Zimbabwean Teachers Strike Over COVID-19 Concerns

HARARE, ZIMBABWE – Zimbabwe resumed in-classroom teaching this week, but thousands of teachers are protesting salaries that are below the poverty level and a lack of personal protective equipment against COVID-19.

Zimbabwe’s Amalgamated Rural Teachers Union says it will only call off the strike when the government addresses the concerns.

“And there is negligence on the part of the authorit(ies) to make sure that there is enough safety to guarantee our teachers and learners from the pandemic,” said Robson Chere, secretary general of the teachers union. “They should have been providing adequate water supply, enough PPEs. Arcturus Primary School, which is down here, hasn’t even water. It’s messy. It’s a disaster. We are sitting on a time bomb for both learners and teachers.”

Authorities did not allow VOA into Arcturus Primary School, which is about 40 kilometers east of Harare.

Some students around Harare have been going to school since Monday to try to learn among themselves, as there are no teachers.

The teachers union warns that classrooms may turn into COVID-19 superspreaders. But Taungana Ndoro, director of communications and advocacy at Zimbabwe’s Education Ministry, says the government has been working to ensure classrooms are safe.

“We have been putting in new infrastructure to ensure that we decongest the existing infrastructure to ensure that there is social and physical distancing for the prevention and management of COVID-19,” Ndoro said.

“We have also made sure that our schools have adequate supplies of sanitizers and water. So, it is looking good. We have got single-seated desks now, instead of two- or three-seated desks. This is to encourage social distancing. We do not have bunk beds anymore in our boarding schools. We have got single beds and spacing of at least one-and-half to two meters. So, it is encouraging.”

UNICEF Zimbabwe has been helping students and the government during the COVID-19 lockdown.

“The two-key approaches were, one: How we can support the loss of learning as a result of school closure. The second one was: How to keep the school safe and ready for children to return to school,” said Niki Abrishamian, UNICEF Zimbabwe’s education manager. “We managed to produce more than 1,600 radio lessons as part of alternative learning approaches. We had to look at how to take learning to the children, especially when they were at home and did not have access to schooling.”

Zimbabwe’s teachers hope such organizations can assist the government and supply the resources they require — adequate PPEs against COVID-19 and salaries that allow them to live above the poverty line.

Zimbabwe currently has 124,773 confirmed coronavirus infections and 4,419 deaths, according to Johns Hopkins University, which is tracking the global outbreak.
