Stock market investors often rely on financial risk theories that help them maximize returns while minimizing financial loss due to market fluctuations. These theories help investors maintain a balanced portfolio to ensure they’ll never lose more money than they’re willing to part with at any given time.

Inspired by those theories, MIT researchers in collaboration with Microsoft have developed a “risk-aware” mathematical model that could improve the performance of cloud-computing networks across the globe. Notably, cloud infrastructure is extremely expensive and consumes a lot of the world’s energy.

Their model takes into account failure probabilities of links between data centers worldwide Â— akin to predicting the volatility of stocks. Then, it runs an optimization engine to allocate traffic through optimal paths to minimize loss, while maximizing overall usage of the network.

The model could help major cloud-service providers — such as Microsoft, Amazon, and Google — better utilize their infrastructure. The conventional approach is to keep links idle to handle unexpected traffic shifts resulting from link failures, which is a waste of energy, bandwidth, and other resources. The new model, called TeaVar, on the other hand, guarantees that for a target percentage of time — say, 99.9 percent — the network can handle all data traffic, so there is no need to keep any links idle. During that 0.01 percent of the time, the model also keeps the data dropped as low as possible.

In experiments based on real-world data, the model supported three times the traffic throughput as traditional traffic-engineering methods, while maintaining the same high level of network availability. A paper describing the model and results will be presented at the ACM SIGCOMM conference this week.

Better network utilization can save service providers millions of dollars, but benefits will “trickle-down” to consumers, says co-author Manya Ghobadi, the TIBCO Career Development Assistant Professor in the MIT Department of Electrical Engineering and Computer Science and a researcher at the Computer Science and Artificial Intelligence Laboratory (CSAIL).

“Having greater utilized infrastructure isn’t just good for cloud services — it’s also better for the world,” Ghobadi says. “Companies don’t have to purchase as much infrastructure to sell services to customers. Plus, being able to efficiently utilize data center resources can save enormous amounts of energy consumption by the cloud infrastructure. So, there are benefits both for the users and the environment at the same time.”

Joining Ghobadi on the paper are her students Jeremy Bogle and Nikhil Bhatia, both of CSAIL; Ishai Menache and Nikolaj Bjorner of Microsoft 

Research; and Asaf Valadarsky and Michael Schapira of Hebrew University.

On the money

Cloud service providers use networks of fiber optical cables running underground, connecting data centers in different cities. To route traffic, the providers rely on “traffic engineering” (TE) software that optimally allocates data bandwidth — the amount of data that can be transferred at one time — through all network paths.

The goal is to ensure maximum availability to users around the world. But that’s challenging when some links can fail unexpectedly, due to drops in optical signal quality resulting from outages or lines cut during construction, among other factors. To stay robust to failure, providers keep many links at very low utilization, lying in wait to absorb full data loads from downed links.

Thus, it’s a tricky tradeoff between network availability and utilization, which would enable higher data throughputs. And that’s where traditional TE methods fail, the researchers say. They find optimal paths based on various factors, but never quantify the reliability of links. “They don’t say, ‘This link has a higher probability of being up and running, so that means you should be sending more traffic here,” Bogle says. “Most links in a network are operating at low utilization and aren’t sending as much traffic as they could be sending.”

The researchers instead designed a TE model that adapts core mathematics from “conditional value at risk,” a risk-assessment measure that quantifies the average loss of money. With investing in stocks, if you have a one-day 99 percent conditional value at risk of $50, your expected loss of the worst-case 1 percent scenario on that day is $50. But 99 percent of the time, you’ll do much better. That measure is used for investing in the stock market — which is notoriously difficult to predict.

“But the math is actually a better fit for our cloud infrastructure setting,” Ghobadi says. “Mostly, link failures are due to the age of equipment, so the probabilities of failure don’t change much over time. That means our probabilities are more reliable, compared to the stock market.”

Risk-aware model

In networks, data bandwidth shares are analogous to invested “money,” and the network equipment with different probabilities of failure are the Â“stocks” and their uncertainty of changing values. Using the underlying formulas, the researchers designed a “risk-aware” model that, like its financial counterpart, guarantees data will reach its destination 99.9 percent of the time, but keeps traffic loss at a minimum during 0.1 percent worst-case failure scenarios. That allows cloud providers to tune the availability-utilization tradeoff.

The researchers statistically mapped three years’ worth of network signal strength from Microsoft’s networks that connects its data centers to a probability distribution of link failures. The input is the network topology in a graph, with source-destination flows of data connected through lines (links) and nodes (cities), with each link assigned a bandwidth.

Failure probabilities were obtained by checking the signal quality of every link every 15 minutes. If the signal quality ever dipped below a receiving threshold, they considered that a link failure. Anything above meant the link was up and running. From that, the model generated an average time that each link was up or down and calculated a failure probability — or “risk” — for each link at each 15-minute time window. From those data, it was able to predict when risky links would fail at any given window of time.

The researchers tested the model against other TE software on simulated traffic sent through networks from Google, IBM, ATT, and others that spread across the world. The researchers created various failure scenarios based on their probability of occurrence. Then, they sent simulated and real-world data demands through the network and cued their models to start allocating bandwidth.

The researchers’ model kept reliable links working to near full capacity while steering data clear of riskier links. Over traditional approaches, their model ran three times as much data through the network, while still ensuring all data got to its destination. The code is freely available on GitHub.

There has been a paradigm shift in the role of fitness in our daily lives. Initially, fitness was more of a time spending activity. The role of fitness is ever increasing, thanks to the engrossing culture of junk food, an unhealthy lifestyle which gained a lot of acceptance at the beginning of the 21st Century. People are building awareness and recognising the need for fitness. Be it gym, pilates, yoga, functional movements, sports- fitness in different forms offer a ray of hope for people suffering from body image issues. Rampant Capitalism has ensured that companies bank on this complex for their gains. Unhealthy food, overconsumption of food, negligence of proper macronutrients, untimely meals, empty calories, skipping meals- they all contribute to the cause.

Mansi Bagla, for the longest time, has been heading the realm at “Mini Homes”, one of the leading Mumbai-based real estate investment firm. The young entrepreneur has now ventured into a new business as she’s put her foot into the world of showbiz. 

She recently announced her dream project, a production house called ‘Mini Films’. The production house recently made its first announcement with Ad Filmmaker Lloyd Baptista as they are all set to introduce an Urban-Mytho-Superhero film, K 7 – the story of seven immortals.

 Mansi who has always been a cinema lover, said, “I have been in the real estate industry for years now. But I’ve always felt the desire and need to pursue my dream of creating good valuable content-driven cinema. I am a total cinema lover and have studied and supervised scripts as a hobby. But with Mini Films, I have decided to take a step forward and I am looking to entertain the masses with good storytelling. When you walk with purpose, you collide with destiny. And I know I will write my own.”

Mansi’s Mini Films have already signed on a few directors for upcoming projects which will be announced soon. By her Birthday which is on 31st August, she plans to announce a few more projects ranging from 10crore to 100 crore bracket.

Today, we have unfortunately become a world where everything is about money, mistrust, deceiving others, getting in wrong businesses etc. But, someone has shown us hope. Even when many of them are on the wrong path to become successful, a person has shown us today what it is to be a good human being first. What it is to be a man with love in his heart & compassion in his work. 

We are talking about Dr Brajesh Yadav, who has many feathers on his hat. He is not only a Doctor but also an Entrepreneur, Producer in the film industry, Trader, Liasoner, Tech-savvy & most importantly, a Social worker.

Ever imagined what all goes into the mind of a person who is donning so many hats, who knows there are many responsibilities that he must fulfil so that he is successful in doing something for the society as a whole for their betterment.

Well, Dr Brajesh’s mere thought of making the society a better place to live in & thinking only about the welfare of people goes to show what an incredible human Dr Brajesh is. He teaches us that humanity has no language. That anybody & everybody must first become a good human being & must always think of other’s welfare to become successful in their own lives eventually.

Dr. Brajesh Yadav comes from a small village called Etah from Uttar Pradesh. He did his primary education from Bhadki (Uttar Pradesh) & completed his secondary school from Etah. He got his degree from Agra & for higher studies got shifted to Pune.

After completing his education, he started his IT business by opening his software company & named it Techno Thoughts IT services. Today his company is spread across so many cities in India as well as other countries. In India, it is spread across Gujarat, Haryana, Andhra Pradesh, Karnataka, West Bengal, Gurugram etc. And, also it is making a name in countries like Dubai, Malaysia, America, etc.

This man at a very young age has done so much of social work for the society that it is hard to believe in today’s world. Also, he credits this attitude of his to his parents. His parents were equally a part of societal welfare. They used to work a lot for their village & their people & Dr Brajesh has been following their footsteps ever since.

He is the one who has made electricity available in many villages. He is the one who did not take any dowry in his wedding whereas taking or giving dowry is commonplace in remote areas of India. He is also working towards providing jobs in all the villages. 

He has won many accolades and many universities have honored with Doctorate for his contributions for the welfare of people.

Dr Brajesh Yadav is doing so much for the society in his own way. He is doing great work not only with his IT business but also in the healthcare industry for the betterment of the needy. He also aspires to join politics soon so that he reaches more & more people & can work towards their betterment. What a good cause & what a good man. Truly humanity at it’s best. 

There is so much to learn from people like Dr Brajesh Yadav. That, no matter what position you are at no matter how far you can help a needy, important is to go ahead & help people around you in whatever way you can & have compassion for them & the attitude of doing something for their betterment.

Can you be unique yet ordinary? Or can you be different yet unique?  Well, Saanya Bajaj, a lawyer by education and a creator of digital content, has perfected these skills and amalgamated the same into a perfect life for herself along with her dashing army officer husband. Saanya, 26, projects a deep understanding of life so far, which probably stems from the fact that this budget-traveler couple put aside a month every year to visit a new place. So far, Saanya, with her hubby, has visited more than 15 countries, some of which are France (there is an interesting story behind it), Spain, Italy, Vietnam, Sri Lanka, and Thailand. 

Based in Pune, Maharashtra, this bubbly girl treats life as one long journey, where the destinations keep changing every year. And all this is reflected on her Instagram handle – @thatordinarycouple! Together, Saanya and her husband have created a vibrant world on this social medium, through which they inspire would-be travellers with amazing glimpses of their travelling life! Though Saanya loves her work that requires her to create digital content for brands and help upcoming brands in finding their feet in the market, she looks forward to that one month of being footloose somewhere out in the world! 

The social media bug bit Saanya back in 2016, when she started blogging and put up her current Instagram profile picture – a romantic kiss against a bright Paris sky atop the Eiffel Tower! No prizes for guessing that the photograph went viral immediately, surprising the couple. It was then that Saanya realized what a wonderful career social media could be turned into. However, for her, life on social media is not about frivolous party hopping or mindless posing in front of the camera. She has carefully crafted a social media personality through her accounts and blog, which acts like a glimpse into her daily life. Here, it is important to mention that their happening life is dominated by their little terrier – lovingly christened pixiethemixie! 

Having met her then boyfriend-now husband as well pixiethemixie on Facebook, Saanya believes it is useless to fret over the future. Instead, she knows life can be unpredictable, so she lets life take her wherever it wants to. Between budget travelling and living life as an army wife, Saanya doesn’t forget to enjoy the ordinary things in life. Her life story, so far, is not only relatable among the millennials but also inspiring for everyone looking for something extra in life. Her philosophy in life – “If I can help even one person feel happy about their day, then I think my job is done!” Sweet, yet profound, no!

It is rightly said a person who is never afraid of failure wins every battle of life. Failures are stepping stone for more concrete and stable business life. The best example is EMRE CAN AYAYDIN.

Emre Can Ayaydin is very flexible, and that is the reason for his success until now. He is a different kind of entrepreneur; he knows how to pass every hurdle of business. According to him, only you can lift and help yourself in life; no one will come and help you in a tough situation.

Emre is planning to expand his business in Asian countries. He feels India is the place where he will get a considerable market to showcase his new design jewelry and other accessories. So he is planning to launch his ASHLEY brand in India in a short time. To start any company we all know, you need a good marketing strategy. Time has changed, and we have come a long way from print media; now people are looking at everything in mobile and computers. So he needs faces which can give a good start in India so that people can identify themselves with the brand.

Rumors say Emre is in touch with one of the most renowned personalities of India, Mohit Kathuria. His name comes from the fittest and he is considered the most handsome man of India. He runs the magazine called Fit look, and he is one of the topmost fitness consultants of India. He has transformed many lives with his fitness program.

Emre wants the face like Mohit for his company, ASHLEY in India. He feels it would be great if he and Mohit collaborate for his dream project in India. It can benefit both of them. Mohit will get the chance to work for an international company and Emre will get a perfect face for his brand, which can give an ideal start to his company in India.

Time will say whether both personalities are collaborating or not in the near future. But if they work, then it will surely benefit both Emre Can Ayaydin as well as Mohit Kathuria.

Malvika Gupta is one of the emerging players in the blogging game. She is an advertising student who is living her life in the blogging world. Her main forte is beauty, fashion and travel blogs. She strongly feels that her travel stories, make-up videos and the exemplary sense of style are what defines her. Blogging has always been her passion and she feels happy about it as her work speaks about it today.

She did her schooling from Delhi Public School. She pursued Bachelor’s in Journalism and Mass Communication and did her masters in the field of advertising. She even worked for a popular website for 3 months but later she realized to start something of her own. That’s when she came up with her blog ‘Styleonwings’ and today it has been 6 years she has been in the blogging industry. 

Talking about the content on her blog, she believes to create the content not just for brands but also for the audience; thus keeping a proper balance between the two. However, her first collaboration was a barter with a jewelry brand and since then there has been no looking back for Malvika. From traveling to London for London Fashion Week to collaborating with international brands like Swarovski, Adidas, Aldo, Loreal, Maybelline among others, she has surely come a long way. 

When asked about how she sees herself as a competition among other bloggers, she said, “There is competition everywhere. But I compete with myself and I like improving my work and staying dedicated to myself. I do what I really want to. People must understand to be themselves rather than trying to be someone else.” On being such an influential personality on the social media, Malvika thanked her fans and followers who for making her what she is today.

Mimi Ikonn has been a true inspiration and the force of the motivation for her. Taking her blog to the next level, Malvika wishes to have her own app which will bring her one step closer to her followers. She has special advice for all the aspiring bloggers. Malvika Gupta was quoted saying, “Do it if you love it. Nothing worth having comes easy so keep going.”

Modeling has always been tempting to every individual. It is not just fame or popularity but also the way you carry yourself. There are millions of people who try their hand in modeling but only a few get to be the one. The main quality one must possess to get into modeling is good looks. With good looks, one must also have the confidence to walk the ramp. Well, there’s a model named Prafful Meghwanshi who has been making noise in the modeling world.

Hailing from the city of lakes, Udaipur, he was a part of Frankfinn Institue of Modelling and Acting. He has walked the ramp at several shows and has become a significant name in a very short period. He has been everyone’s first choice to walk as a showstopper in fashion events. Before getting into modeling, Prafful wanted to be an engineer and he completed his civil engineering from Jaipur. 

However, his inclination towards modeling saw him opting for modeling as a career. Till now, he has won many big fashion shows in Rajasthan and New Delhi. He had been a part of the men’s fashion show which was directed by Liza Verma in the capital city of our country. While Prafful has been into this field for a long time now, he makes sure to keep himself fit as it is a pre-requisite to be a top model. Apart from having good looks, the young lad is blessed with a sharp mind. 

Looking at his confidence and self-belief, we don’t mind saying that he will become one of the top models soon. Talking about his love for modeling, Prafful said, “Modelling has been my forte and I love to take over the stage. I have always loved to experiment with my looks and going in sync with the latest fashion trends is what I love the most.” When asked about his future plans, he revealed that he is preparing himself and wants to represent himself as a model on an international level.

Cricket is not just a sport but a religion in India. Whenever there is any cricket tournament, the fans from every nuke and corner of the country go crazy for the sport. The game of cricket is said to be the most loved sport. In today’s time, there have been many sports platforms where people or say sports experts give their opinion about any particular game. Anurag Dwivedi is one of the most talked names when we speak about cricket experts. He has been widely followed by the people on social media. 

Based on the game of cricket, there are many fantasy and sports gaming platforms out of which Dream11  is one of the most popular platforms. Anurag Dwivedi has been actively a part of the Dream11 contest and is widely considered as the best cricket expert today. In this fast-paced world, the young lad keeps his followers notified about the happenings in the world of cricket, be it on-field or off-field.

Moreover, Anurag is known for his previews and predictions ahead of any match. Right from domestic cricket to international cricket, he has always kept his followers updated about the game. As far as the contests and challenges are concerned in fantasy cricket, he has most of the times been accurate. That is what has made him a genius expert in the field of cricket. He enjoys a great fan following on YouTube and his channel has more than 117K followers. One of the best things about his YouTube videos is that he has been giving timely updates about any particular game and his advice for the Dream11 team has made many people win many contests in the fantasy game. 

The young entrepreneur has been very fond of cricket and speaking about the same, he said “Since my childhood, I have been following the game of cricket. It gives me real joy when people consider my advice as expert advice. More than that, I feel happy because as per my knowledge I try to make them win the fantasy game and it is a great feeling when people start recognizing me as a known cricket expert.”
