One model at a time: Integrating and running Deep Learning models in production at EyeEm
This is a guest by Michele Palmia, now @EyeEm, good times @IBM, @UniPd and @UCC.
We’ve now been running computer vision models in production at EyeEm for more than three years – on literally billions of images. As an engineer involved in building the infrastructure behind it from scratch, I both enjoyed and suffered the many technical challenges this task raised. This journey has also taught me…

New Book: Explain the Cloud Like I'm 10
New Book: Explain the Cloud Like I’m 10
What is the cloud? Why is it called a cloud? How does the cloud work? What does it mean when something is ‘in the cloud’?
I wrote a new book: Explain the Cloud Like I’m 10, answering those questions for the complete beginner. It makes the perfect gift for Halloween. And Thanksgiving. And Christmas. Oh, and birthdays too!
The irony is, if you read HighScalability, you’re not the target audience 🙂

Results of some googling over concerns about AWS Elastic Load Balancers' ability to handle 30K+ concurrent requests/sec. Research indicates this is not a problem (depending on how quickly that traffic grows):
http://www.rightscale.com/blog/cloud-management-best-practices/benchmarking-load-balancers-cloud # the canonical benchmark of LBs on AWS
https://harish11g.blogspot.com/2012/07/aws-elastic-load-balancing-elb-amazon.html # see point 4, but this was also 4 years ago
https://www.jayway.com/2015/04/13/600k-concurrent-websocket-connections-on-aws-using-node-js/ # EC2 without ELB, using node.js and kernel tuning
http://blog.flux7.com/blogs/aws/must-know-facts-about-aws-elb
http://shlomoswidler.com/2009/07/elastic-in-elastic-load-balancing-elb.html # testing elasticity in ELB (mostly overlaps with AWS whitepaper below)
https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html # service limits for AWS in general; useful reference
https://aws.amazon.com/articles/1636185810492479 # AWS whitepaper on best practices for evaluating ELB
https://aws.amazon.com/documentation/elastic-load-balancing/ # formal ELB documentation
https://lab.getbase.com/how-we-discovered-limitations-on-the-aws-tcp-stack/
https://coderwall.com/p/__z9ia/scale-php-on-ec2-to-30-000-concurrent-users-server
https://blog.unitedheroes.net/archives/p/4633/how-many-sockets-does-aws-support-anyway/ # AWS EC2 websockets support per instance
tl;dr - ELB is effectively unlimited, but you need to pre-warm the ELB if you are expecting an abrupt spike in traffic (see https://aws.amazon.com/articles/1636185810492479#pre-warming)
