Taiji: managing global user traffic for large-scale Internet services at the edge

The Morning Paper

Taiji: managing global user traffic for large-scale internet services at the edge Xu et al., It’s another networking paper to close out the week (and our coverage of SOSP’19), but whereas Snap looked at traffic routing within the datacenter, Taiji is concerned with routing traffic from the edge to a datacenter. Traffic load is measured using requests per second for stateless traffic, and as the number of user sessions for sticky traffic.

How It Works: BULK INSERT (BCP) TDS Traffic

SQL Server According to Bob

Yesterday I had a discussion with a customer and realized that the BCP, TDS pattern could use a bit of documentation. Customer Scenario/Question: I am using BCP.exe to import a large data set. BCP.exe takes 15 minutes to complete but I only see a few seconds for the BULK INSERT command when monitoring dm_exec_requests. What is taking so long if the BULK INSERT is only showing a few seconds in dm_exec_requests? The customer was correct in her observation.

Why Load Balancing Is Important for Web Servers?

DZone

In the web hosting service industry, it is commonly used for balancing the HTTP traffic across multiple servers which act together as a web front-end.

In case if one of the server nodes fails, the traffic can be programmatically distributed to other nodes without any service interruption. What is Load Balancing?

Redis vs Memcached

Software Architecture

Memcached is very good at handling high traffic websites. Redis can not handle heavy traffic on read/write. Memcached is in-memory key value store whereas Redis is in-memory data structures store.

Evolving Regional Evacuation

The Netflix TechBlog

In the event of an isolated failure we first pre-scale microservices in the healthy regions after which we can shift traffic away from the failing one. This pre-scaling is necessary due to our use of autoscaling, which generally means that services are right-sized to handle their current demand, not the surge they would experience once we shift traffic. So, if we evacuate South American traffic to North America, demand for CE and Android DRM won’t grow uniformly.
