    re:Invent 2020 Liveblog: Andy Jassy Keynote

    I’m always ready to try something new! This year, I am going to liveblog Andy Jassy‘s AWS re:Invent keynote address, which takes place from 8 a.m. to 11 a.m. on Tuesday, December 1 (PST). I’ll be updating this post every couple of minutes as I watch Andy’s address from the comfort of my home office. […] [Read More]

    New –  Attribute-Based Access Control with AWS Single Sign-On

    Starting today, you can pass user attributes in the AWS session when your workforce sign-in into the cloud using AWS Single Sign-On. This gives you the centralized account access management of AWS Single Sign-On and ABAC, with the flexibility to use AWS SSO, Active Directory, or an external identity provider as your identity source. To […] [Read More]

    Introducing Amazon Managed Workflows for Apache Airflow (MWAA)

    As the volume and complexity of your data processing pipelines increase, you can simplify the overall process by decomposing it into a series of smaller tasks and coordinate the execution of these tasks as part of a workflow. To do so, many developers and data engineers use Apache Airflow, a platform created by the community […] [Read More]

    New – Code Signing, a Trust and Integrity Control for AWS Lambda

    Code signing is an industry standard technique used to confirm that the code is unaltered and from a trusted publisher. Code running inside AWS Lambda functions is executed on highly hardened systems and runs in a secure manner. However, function code is susceptible to alteration as it moves through deployment pipelines that run outside AWS. […] [Read More]

    New – Multi-Factor Authentication with WebAuthn for AWS SSO

    Starting today, you can add WebAuthn as a new multi-factor authentication (MFA) to AWS Single Sign-On, in addition to currently supported one-time password (OTP) and Radius authenticators. By adding support for WebAuthn, a W3C specification developed in coordination with FIDO Alliance, you can now authenticate with a wide variety of interoperable authenticators provisioned by your […] [Read More]

CloudLinux OS is too slow

CloudLinux OS has been invented to throttle (down) the speed of a server, by limiting the maximum CPU amount an account can use. This is was relevant before (when PHP-FPM did not exist) but today it became completely useless. Overall it is even worse: the CPU time used by CloudLinux OS is even slowing down the server even more! 🕓

It is very easy to understand why:

  • let’s say that you have a spike of traffic and you need 20 seconds of CPU time to serve this spike
  • because of the throttling by CloudLinux OS: typically you only have access to 25% of the max CPU (could be even less!) 💩
  • it is now easy to understand that it will take 4 times longer for you to get your 20 seconds of CPU time because of CloudLinux OS. 🐌

You can consider this graphic which sums it up perfectly:

CloudLinux VS non-CloudLinux OS

CloudLinux will take 4 more times
