Google Meet reached 100 million daily meeting participants

Google has revealed how it scaled its Google Meet to meet the demand for online meetings during the coronavirus pandemic.

“As COVID-19 turned our world into a more physically distant one. Many people began looking to online video conferencing to maintain social, educational and workplace contact.” – Samantha Schaevitz, staff site reliability engineer at Google explained, in a blog post. “The virus’s growing impact on how people were working, learning and socializing with friends and family translated to a lot more people looking to services like Google Meet to keep in touch.”

On Feb. 17, Google’s Meet Site Reliability Engineering (SRE) team was being notified about regional capacity issues on the service. “Because Google’s user-facing services are built with redundancy, these alerts didn’t indicate ongoing user-visible issues.” – Schaevitz explained, in the blog post. “But it soon became clear that usage of the product in Asia was trending sharply upward.”

“The SRE team began working with the capacity planning team to find additional resources to handle this increase. But it became obvious that we needed to start planning further ahead, for the eventuality that the epidemic would spread beyond the region,” Schaevitz added.

Italy began its COVID-19 lockdown shortly after, as it attempted to combat the novel coronavirus. Usage of Google Meet in Italy also picked up.

As the Mountain View, Calif.-based firm prepared Google Meet for the demands of the pandemic. Many aspects of the situation were still unknown.

“Most of the social effects of COVID-19 were unknown or very difficult to predict,” Schaevitz added. “Our mission was abstract: we needed to prevent any outages for what had become a critical product for large amounts of new users, while scaling the system without knowledge of where the growth would come from and when it would level off.”

How Google Meet bulked up capacity.

Like many companies around the world, Google was also transitioning to employees working from home. “Without the ability to sit in the same room as everyone else, it became important to manage communication channels proactively to ensure we all had access to the information needed to achieve our goals,” Schaevitz explained.

They set up incident commanders, communications leads and operations leads in both North America and Europe. Schaevitz was an incident commander.

They set up workstreams around capacity, dependencies, bottlenecks and ‘control knobs’ to handle any outages and production changes.

They used Google’s 21 data centers around the world to double the available capacity of Google Meet. However, it quickly became clear that resources would be needed as Google began working toward a 50x growth forecast.

In addition to scaling up its server capacity, Google also sought to make the process of supporting Google Meet more efficient. Schaevitz described this as “the most requests handled at the cheapest resource cost, without sacrificing user experience or reliability of the system.”

This enabled the service to handle 100 million daily meeting participants a day, according to Google. In April, Google CEO Sundar Pichai said the tech giant adding 3 million new users a day, which was a 30-fold increase since January.

Google racked up more than 600 million daily Meet participants in a single week, according to Pichai. (During the company’s second fiscal quarter, which ended on June 30).

Other teleconferencing services have also experienced massive growth as a result of the coronavirus lockdowns and work-from-home orders. Zoom, for example, reached 300 million daily participants by the end of April.

How Nintendo Will Be Celebrating Mario’s 35th Anniversary

This year marks the 35th anniversary of Super Mario Bros. But Nintendo has been particularly quiet for most of this year.

Despite this being a major anniversary for their company’s defining character. Nintendo does not have any major plans in the works to celebrate Mario’s 35th anniversary. Or at least, there are no official plans announced yet.

Rumors have swirled for months as to how Nintendo would be celebrating Mario’s anniversary. With many believing a Super Mario All-Stars Collection could be their big plan. From the news gathered, All-Stars collection is in the works. But there’s no word as to when it might be released. Leaks have also revealed that Super Mario 3D World port will also be coming to the Switch. But again, there is no confirmed release date.

Normally, Nintendo Direct would announce games of this magnitude. But it’s been nearly a year since the last official, full Nintendo Direct and there doesn’t seem to be any planned for the near future. It’s safe to say COVID-19 threw a wrench into Nintendo’s plans for this year.

Still, their company’s Fall and Winter lineups look particularly barren. Which would imply they still have some games yet to be announced. There could be a Nintendo Direct in the works that fans have no knowledge of, or Nintendo could simply announce the game through Twitter, as they did with Pikmin 3’s Switch port.

Nintendo - The 35th anniversary of Super Mario Bros
The 35th anniversary of Super Mario Bros

Super Mario Bros

On September 13th, 1985, An Italian plumber named Mario with a propensity for jumping on mushrooms and turtle shells introduced to the world. From that day on, the platforming genre was the never the same. Since the release of the original Super Mario Bros. Mario has become one of the most recognizable characters in all of gaming and has helped turn Nintendo into the gaming juggernaut they are today. This year marks the 35th anniversary of Nintendo’s signature character and they will roll out the red carpet in celebration.

While it would be surprising if Nintendo completely overlooked Mario’s 35th Anniversary, especially after LEGO and Hasbro made it a point to celebrate, there are only so many months left in the year. If Nintendo wants to make this the year of Mario and celebrate the 35 year anniversary of Super Mario Bros. They’ll need to do something sooner rather than later.

Reverse proxy vs Forward proxy

Proxy hay Proxy Server làm nhiệm vụ đứng giữa client và web server ứng dụng. Nó có vai trò bảo vệ client hoặc webserver tùy theo loại của chúng. Có 2 loại proxy là Reverse proxy vs Forward proxy:

1- Forward proxy thường được sử dụng trong các doanh nghiệp. Nó cùng với với tường lửa, router để bảo vệ, kiểm soát người dùng ra ngoài Internet. Proxy này ghi log, cho phép người dùng được truy cập các trang web nào, thời điểm nào… Đảm bảo tính ẩn danh của người dùng trước các web ghi lại thông tin người truy cập.

2- Reverse proxy thì ngược lại, nó tiến hành bảo vệ web server trước các client. Nó tiến hành ghi log, đứng trước bảo vệ các webserver đằng sau, ngăn không cho client gửi yêu cầu tới webserver trực tiếp. Nó cũng đóng vai trò như các bộ điều hướng, kiểm soát các client để phân bổ tới các ứng dụng định sẵn. Hơn nữa Reverse proxy có thể đóng thêm vai trò cân bằng tải (Load Balancer)

Tìm hiểu tiếp phần này thấy có khá nhiều thứ hay ho. Ta mở rộng thêm các khái niệm về Load Balancer, High-Availability đi kèm là HAProxy và Keepalived.

Đối với Apache thì có các module Proxy, module HAProxy, module Keepalived để làm Cân bằng tải.
Chuyên biệt hơn ta có Piranha Load Balancer, với cấu hình trực quan để làm Load Balancer.

Ta cũng có thể sử dụng NGINX làm proxy cho Apache.
