Google And Friends Add Prometheus To Kubernetes Platform

There are a lot of moving parts in a modern platform, and in this regard, they are no different from the platforms made a generation earlier. But a modern platform has a lot more automation and is handling more dynamic workloads that are popping into and out of existence on different parts of a cluster like quantum particles, and it takes a higher level of sophistication to monitor and manage the stack and the apps running on it.

Frustration with existing open source monitoring tools like Nagios and Ganglia is why the hyperscaler giants created their own tools – Google …

Using the CloudFlare API via Python

Very early on in the company’s history we decided that everything that CloudFlare does on behalf of its customer-base should be controllable via an API. In fact, when you login to the CloudFlare control panel, you’re really just making API calls to our backend services. Over time that API has matured and improved. We are now on v4 of that API.

The current CloudFlare API is documented here and it’s used by both the CloudFlare control panel and directly by umpteen customers every minute of every day. The new API is designed with a clean naming structure and consistent data representation for data. It’s also extensible.

This blog entry introduces python-cloudflare, a Python wrapper providing full access to the CloudFlare v4 API.

An example

Let’s get right into the thick-of-it with the simplest coding example available to show python-cloudflare in action. This example lists all your domains (zones) and also checks some basic features for each zone. 

#!/usr/bin/env python
import CloudFlare  
def main():  
    cf = CloudFlare.CloudFlare()
    zones = cf.zones.get(params={'per_page':50})
    for zone in zones:
        zone_name = zone['name']
        zone_id = zone['id']
        settings_ipv6 = cf.zones.settings.ipv6.get(zone_id)
        ipv6_on = settings_ipv6['value']

How the skills shortage is transforming big data

In the early days of computing, developers were often jacks of all trades, handling virtually any task needed for software to get made. As the field matured, jobs grew more specialized. Now we're seeing a similar pattern in a brand-new domain: big data.That's according to P.K. Agarwal, regional dean and CEO of Northeastern University's recently formed Silicon Valley campus, who says big-data professionals so far have commonly handled everything from data cleaning to analytics, and from Hadoop to Apache Spark.To read this article in full or to leave a comment, please click here

Next Generation Supercomputing Strikes Data, Compute Balance

Although the future of exascale computing might be garnering the most deadlines in high performance computing, one of the most important stories unfolding in the supercomputing space, at least from a system design angle, is the merging of compute and data-intensive machines.

In many ways, merging both the compute horsepower of today’s top systems with the data-intensive support in terms of data movement, storage, and software is directly at odds with current visions of exascale supercomputers. Hence there appear to be two camps forming on either side of the Top 500 level centers; one that argues strongly in favor of …

Sunsetting API v1 In Favor Of CloudFlare’s Current Client API: API v4

Today we’re announcing the sunsetting of CloudFlare’s first client API, API v1. Starting November 9th, 2016 at noon Pacific Time (20:00 UTC), CloudFlare will no longer be supporting API v1.

While it is bittersweet to let our first API from CloudFlare’s early days go, we are so excited to show you all of the great things about our latest API: API v4. We’re confident that once you get started using it, you’ll see how easy API v4 makes managing your CloudFlare settings.

(For those of you who are curious where CloudFlare’s API v2 and v3 went, they ran away with IPv5 and PHP 6.)

If you are using API v1 and need to migrate to API v4, we’ve written extensive migration docs here for you to follow. They contain every API call from v1 and their equivalent in v4 side by side.

What will happen after the sunset?

After CloudFlare discontinues support for API v1 in November 2016, any calls to API v1 will return the HTTP status code 410 Gone with the message: “This API has been deprecated in favor of API v4, available at https://api.cloudflare.com.”

What can you do with API v4?
