Last Week on ipSpace.net (2019W12)

Spring started for real, so it was time for some early-spring cleaning and I managed to complete two webinars during last week:

Both webinars are part of standard ipSpace.net subscription

Amazon Aurora: design considerations for high throughput cloud-native relational databases

Amazon Aurora: design considerations for high throughput cloud-native relational databases Verbitski et al., SIGMOD’17

Werner Vogels recently published a blog post describing Amazon Aurora as their fastest growing service ever. That post provides a high level overview of Aurora and then links to two SIGMOD papers for further details. Also of note is the recent announcement of Aurora serverless. So the plan for this week on The Morning Paper is to cover both of these Aurora papers and then look at Calvin, which underpins FaunaDB.

Say you’re AWS, and the task in hand is to take an existing relational database (MySQL) and retrofit it to work well in a cloud-native environment. Where do you start? What are the key design considerations and how can you accommodate them? These are the questions our first paper digs into. (Note that Aurora supports PostgreSQL as well these days).

Here’s the starting point:

In modern distributed cloud services, resilience and scalability are increasingly achieved by decoupling compute from storage and by replicating storage across multiple nodes. Doing so lets us handle operations such as replacing misbehaving or unreachable hosts, adding replicas, failing over from a writer to a replica, scaling the size Continue reading

Relentless Competition Drives Down Ethernet Switch Costs

If you want to see what real competition might look like at some point in the future of the server racket, look no further than the Ethernet switch market, where switch ASICs and the companies that build switches alike have to fight for every dollar and make it up in volume every year without pause. … “Relentless Competition Drives Down Ethernet Switch Costs”

Heavy Networking 437: Melding Policy And Technology With The Internet Governance Project

On today's Heavy Networking we explore the intersection of policy, politics, and technology with the Internet Governance Project (IGP), which connects tech and policy experts to help bridge gaps in understanding between these two communities, with the goal of influencing outcomes on issues such as free expression, privacy, and security.

The post Heavy Networking 437: Melding Policy And Technology With The Internet Governance Project appeared first on Packet Pushers.

A Full CI/CD Pipeline for Workers with Travis CI

A Full CI/CD Pipeline for Workers with Travis CI
A Full CI/CD Pipeline for Workers with Travis CI

In today’s post we’re going to talk about building a CI/CD pipeline for Cloudflare Worker’s using Travis CI. If you aren’t yet aware, Cloudflare Workers allow you to run Javascript in all 165 of our data centers, and they deploy globally in about 30 seconds. Learn more here.

There are a few steps before we get started. We need to have a Worker script we want to deploy, some optional unit tests for the script, a serverless.yml  file to deploy via the Serverless Framework, a .gitignore file to ignore the node_modules folder, and finally, a .travis.yml configuration file. All of these files will live in the same GitHub repository, which should have a final layout like:

----- worker.js
----- serverless.yml
----- test
      . worker-test.js
----- node_modules
----- package.json
----- package-lock.json
----- .travis.yml
----- .gitignore

The Worker Script

In a recent post we discussed a method for testing Workers. We’ll reuse this method here to test a really simple Worker script below which simply returns Hello World! in the body of the response. We will name our Worker worker.js.

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request))
})
async function handleRequest(request) {
  return new  Continue reading

However, under some circumstances, BGP communities can be used to drop and redirect traffic. In principle, the same effect can be achieved via BGP hijacks, but community-based attacks are way harder to spot and almost impossible to attribute. —Florian Streibelt

Register an abandoned DNS server domain, and you can redirect querying clients to any destination of your choosing. —Kaan Onarlioglu

The Optical Transport Network (OTN) architecture is now almost two decades old, and some pundits are proclaiming that its role as a distinct transport layer will soon give way to an IP-over-DWDM architecture. —Jonathan Homa
