VMware commercialized the idea of virtual machines, and cloud providers embraced the same concept with services like Amazon EC2, Google Compute, and Azure virtual machines. Serverless computing is a cloud-based, on-demand execution model where customers consume resources solely based on their application usage.

Google Cloud and Microsoft Azure released Scope 3 data in 2021. The last number I saw was “over 20GW”, and Amazon has much better global PPA coverage, including India and China, than Google Cloud and Microsoft Azure, who have very few PPAs in Asia. This session revisits the pillar and its best practices.

Label-based access control is a security mechanism that allows companies to control who can access specific metrics based on their labels. To simplify access management : Label-based access control can simplify access management by allowing companies to assign labels to metrics. Which approach should I use when assigning roles?

You’ll try this with a few other algorithms, and their respective tuning parameters–maybe even break out TensorFlow to build a custom neural net along the way–and the winning model will be the one that heads to production. Especially when you consider how Certain Big Cloud Providers treat autoML as an on-ramp to model hosting.

Key user-centric metrics often depend on the size, number, layout, and loading priority of images on the page. Smaller file size directly impacts the Largest contentful Paint (LCP) metric for the page as image resources needed by the page get loaded faster. However, you should ideally replace such images with videos.
