AWS, Google and Azure are in a price war; and seem committed to matching on-demand prices. That is good, but not the whole story.
The under reported price is that of the AWS spot market; which can be up to 10 x cheaper than on-demand prices.
On-demand / month
Spot / month
There are only 2 differences between AWS spot and on-demand instances.
1. Spot instances take longer to start (5 min vs 1 min)
2. Spot instances “fail” more frequently; when spot prices move above your bid price your instance gets terminated.
You might think that ( 2 ) would prevent you from using spot to host “always on” services like Cloud Foundry.
At the April Cloud Foundry Advisory Board meeting the Performance Acceptance Test (PAT) project, contributed by IBM, was accepted as a new Cloud Foundry incubator project. The idea behind PAT is that there should be a super easy way to test performance of Cloud Foundry installations so that any intended improvements can be proven, and regressions can be caught before the new code goes live.
High level overview of the PAT tool
PAT was originally created at the start of 2014 when it was noticed that a previous load testing tool project called Stac2 had gone stale, leaving an important gap in the Cloud Foundry CI/CD story that needed filling.
Pivotal CEO Paul Maritz wrote about Cloud Foundry back in February when we announced our intention to form the non-profit Cloud Foundry Foundation. The Foundation aims to formalize Pivotal’s commitment to the open governance of a new platform that serves businesses in a multi-cloud world, anchored around Cloud Foundry.
I’m delighted with Pivotal’s announcement of the eight new Gold level members who have stated their intention to join the Cloud Foundry Foundation when it launches this Fall. They include Accenture, BNY Mellon, Capgemini, Ericsson, GE, Intel, NTT and Verizon, bringing the total level of Platinum and Gold members to 17.
Software continues to disrupt every aspect of the consumer and enterprise experience.
