Microsoft and Oracle partner to link cloud services

Microsoft Corp. and Oracle Corp. on Wednesday announced a cloud interoperability partnership enabling customers to migrate and run mission-critical enterprise workloads across Microsoft Azure and Oracle Cloud. Enterprises can now seamlessly connect Azure services, like Analytics and AI, to Oracle Cloud services, like Autonomous Database. By enabling customers to run one part of a workload within Azure and another part of the same workload within the Oracle Cloud, the partnership aims to deliver a highly optimized, best-of-both-clouds experience.
“As the cloud of choice for the enterprise, with over 95 percent of the Fortune 500 using Azure, we have always been first and foremost focused on helping our customers thrive on their digital transformation journeys,” said Scott Guthrie, executive vice president of Microsoft’s Cloud and AI division.

“With Oracle’s enterprise expertise, this alliance is a natural choice for us as we help our joint customers accelerate the migration of enterprise applications and databases to the public cloud.”
“The Oracle Cloud offers a complete suite of integrated applications for sales, service, marketing, human resources, finance, supply chain and manufacturing, plus highly automated and secure Generation 2 infrastructure featuring the Oracle Autonomous Database,” said Don Johnson, executive vice president, Oracle Cloud Infrastructure.
“Oracle and Microsoft have served enterprise customer needs for decades. With this partnership, our joint customers can migrate their entire set of existing applications to the cloud without having to re-architect anything, preserving the large investments they have already made.”


YORK’s sustainable cooling solutions in Grand Mosque

YORK’s sustainable cooling solutions in Grand Mosque

HVAC company Al-Salem Johnson Controls (YORK), which operates the “Ajyad” and “Al-Shamiya” cooling stations located in Makkah’s Grand Mosque, ensured that pilgrims performing the Hajj rituals this year did so in a cool and pleasant atmosphere inside Al-Haram.
“YORK is proud to serve the guests of Allah in Makkah Al-Mukarramah by accompanying the pilgrims in their Hajj rituals and providing a fresh and cool ambience throughout their Hajj journey, especially in Makkah’s Grand Mosque,” the company said.
According to YORK, the total cooling capacity of the two cooling plants is 159,000 tons (equivalent to the cooling required for 15,000 medium-sized apartments). YORK chillers pump the chilled water to more than 1,000 Saudi-made air handling units (AHUs) located inside the Grand Mosque, which then distribute 100 percent fresh and cool air that reaches every corner of Al-Haram. The chillers’ latest technologies and the AHUs’ highly efficient filtration system help to maintain the required temperature and humidity levels necessary for ensuring a comfortable ambience for the pilgrims.
The cooling capacity is regulated by the number of pilgrims and worshippers inside the Grand Mosque. Thus, owing to the reduced number of pilgrims this year, the total cooling capacity was halved to nearly 80,000 tons (equivalent to the cooling of 8,000 medium-sized apartments), provided through 63 YORK chillers located inside the Ajyad and Al-Shamiyah cooling plants.

Owing to the reduced number of pilgrims this year, the total cooling capacity was halved to nearly 80,000 tons, provided through 63 YORK chillers located inside the Ajyad and Al-Shamiyah cooling plants in the Grand Mosque.

The company has designed a highly efficient and smart ventilation, air conditioning and refrigeration system for Al-Haram, taking into account the crowded nature of the location as well as the ability of the cooling stations to adapt to the Grand Mosque’s ongoing expansion project.
The Al-Shamiyah plant, which is one of the two world’s largest cooling plants of its kind, contains 24 YORK OM centrifugal chillers. The chillers have been customized and engineered especially to meet the requirements of the Grand Mosque. Its special industrial design helps in long-term operation with high efficiency, while the variable-speed drive (VSD) technology contributes in reducing the annual energy consumption by about 30 percent, in addition to reducing the amount of sound.
These chillers feature “smart control,” which enables the chillers to estimate the rate of congestion inside Al-Haram by calculating the difference between the temperature of the water that is pumped to and from the mosque. Accordingly, the chiller increases or decreases the cooling capacity in proportion to the size of the crowds inside the mosque. The plant offers sustainable cooling solutions as its chillers use a chilled water system with an eco-friendly refrigerant.
In addition to the more than 100 operation and maintenance technicians stationed around the clock inside the Grand Mosque to ensure the efficient operation of the cooling stations and quick handling of any untoward incidents, the company dedicated an additional response team during Hajj to quickly respond to any maintenance requests or emergency situations.
